The main purpose of this study was to analyse the temperatures generated during the bone bed preparation, given the internal structure of the bone bed, the geometry of the hole, and the treatment parameters such as the type of cooling and the rotational speed of the drill. The investigated material was domestic pig ribs, in which holes were drilled three times using two drill bit systems used for Hiossen® and Paltop® dental implantation. The ThermaCAM® P640 thermal imaging camera was used for measurement of drilling temperatures. After the holes were drilled, each rib was examined using the 1172 SkyScan microtomograph, Bruker®, to compare the geometry of the machined holes. The presented study proved that larger diameter drill bits (Hiossen® drill bits) generate more heat during the machining process, as evidenced by higher temperatures obtained for the Hiossen system in each case. It was proved that rotational speed, drill bit diameter and cooling system have a significant effect o...

Since the Komodo dragon has been included on The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, it is crucial to know in detail its biology as there is a limited availability of research material on these animals—mainly those who died in zoos or whose remains were found in the wild. Anatomy is essential for understanding physiology, identification of diseases, adaptations in the environment, and behavior. In this dissection study, the relationship of individual anatomical structures was analyzed, the anatomy of the active and passive movement system of the thoracic limb was described, photographs were taken, and a radiographic examination was conducted. This species has its own differences, even within closely related lizard species. Varanus komodoensis possesses triceps muscles with three heads, and the wrist is extended with additional bones for greater flexibility of the hand. The muscles of the forelimb are analogous to the hind limb; howev...

There are many cysts and tumors which might occur in the mandibular and maxillary bones. Their origin can be either odontogenic or non-odontogenic. One of the most common odontogenic cysts is the odontogenic keratocyst (OKC). Its nomenclature and classification have changed many times over years, from a tumor to, finally, a cyst. Nowadays, its treatment has not greatly changed, however, it is related to a potential recurrence rate more than any other cyst of odontogenic origins. OKC size, localization, and possible cortical expansion towards adjacent soft tissues might influence the scope of treatment and possible reoccurrence in time. Each case is quite individual, and after removal of the pathology in some cases there can be a necessity for either bone grafting or any other reconstruction method to restore proper bone continuity. The size and the placement of OKC might influence pathological fracture occurrence or inappropriate healing if the bone cavity after cyst removal is not ...

Introduction. The presence of bone septum in the maxillary sinus is one of the most common anatomical findings. So-called Underwood septa (US) are an atypical bone formation in the maxillary sinuses. Mostly they are quite easily found in CBCT studies and have major importance in sinus lift procedures in dental surgery. Furthermore, the shape, location, and size of the bony septa are important in each maxillary sinus surgery. Material and methods. A retrospective study of 120CBCT scans from the authors’ own database was conducted. Results. Approximately 37.5% of each CBCT was associated with the occurrence of US, while just 25% had a full septum, and a total of only 14 patients had a half septa. More females have US, while healthy pneumatized maxillary sinus is most commonly found (82.22%). There is no correlation between the occurrence of silent sinus syndrome (p = 0.174), mucosal thickening (p = 0.325), or retention cyst formation (p = 0.272). Most sinuses are without any opacifica...

The buccal fat pad, also called the Bichat’s fat pad (BFP), is an encapsulated fat mass located in the cheek. This type of specialized fat mass can be used both as a pedicular or free graft in various surgeries and approaches. Due to its easy access from the oral cavity approach, it is commonly used for oroantral and palatal fistula closure. The knowledge of its anatomy and surrounding tissues plays a role in its mobilization and suturing onto the desired defect in the palatal or maxillary region. The BFP is mostly associated with the primary approach used for a fistula or bone surgery. Alternatively, the procedure can be performed with a single approach incision, which does not compromise the appearance or the function of the operating or adjacent areas. The most important inclusion criteria for BFP usage and surgical limitations are highlighted. The BFP is used for multiple purposes in reconstructive and oncology surgery and also has its use in esthetic and facial contouring proce...

Introduction. Facial asymmetry might have many etiological factors. Most known and recognized factors are related to hemimandibular hyperplasia, elongation, condyle-related pathologies hemifacial microsomia, laterogenia, and others. In some cases, however, facial asymmetry has a different origin within the maxillary sinus (MS) bones. This rare entity as a silent sinus syndrome (SSS) causes secondary midfacial and maxillary asymmetry because of the retraction of the sinus walls. The authors present their own proposal for SSS/CMA (chronic maxillary atelectasia) classification and possible maxillary sinus disease alterations related to the scope of changes in the maxillary sinus walls, asymmetry, opacification, and related features. Material and Methods. The study consisted of 131 CBCT images which were evaluated. The authors focus on fourteen retrospective cone beam-computed tomography studies (CBCT) performed to establish and evaluate sources of facial asymmetry. Results. Neither pre...

The usage of xenograft material is widely used in almost all oral cavity bone defects for regenerative and reconstructive purposes. The presented xenograft usage in the following care report enabled good bone defect healing and enabled the preservation of affected premolars. It is quite common to use any possible variations of bone materials to ensure bone defect improved healing. In some cases, the scope of surgeries requires the removal of each cyst within close proximity to various nerves and vessels. The inferior alveolar, infraorbital, lingual, and mental nerves are those most commonly adjacent to most operating sites in jaw bones. The usage of some additional materials such as collagen sponges, bone substitutes, resorbable membranes, or other additional materials are useful in each bone defect reconstruction but should be handled with care, as described in the following case. Before planning their usage, it is important to perform each surgery with close cone beam computed tom...

The international problem of poaching and illegal trade in rhino horn has led to the formulation of standards defining human duties towards the natural environment and animals, especially the endangered species. The smuggling of animals and animal products, as well as historical, artistic or archaeological exhibits, required legislators to come up with more stringent and faster penal measures against crime, which also involved the introduction of uniform methods of identification and marking. The movement of personal goods, as well goods exchanged between scientific units has been subjected to stricter control, in which scientific knowledge and consulting bodies play a more important role. This had a definite positive effect on nature conservation in general. In the case of rhinoceroses, however, protection and attempts to restore them to the environment have encountered significant difficulties, which posed both technical and ethical dilemmas for these activities. Other unintended ...

The coronoidectomy approach is a known but still quite underestimated procedure focused on the removal of the coronoid process of the mandible. Most cases related to outer-joint-related factors causing limited mouth opening (LMO) might be related to a great variety of factors. Quite often, patients suffer a lot from the inability to fully open their mouths. During this time, they are scheduled for limitless conservative, pharmacological, and diagnostic steps to estimate the cause of LMO and increase patients’ mouth opening. In those cases, a diagnostic coronoidectomy might be useful to estimate the potential cause of such a problem. On the other hand, a prophylactic coronoidectomy is still quite randomly described in the world literature and mostly selected for a limited number of special cases. Herein, we would like to present a special issue of the major trauma in the temporal bone, middle cranial fossa, and zygomatico-malar area that resulted in temporal muscle contusion, scarrin...

The present study aimed to characterize the macrostructure and microstructure of the mandibular teeth of the Komodo dragon (Varanus komodoensis) and the methods it uses to obtain food. Examinations were performed using a stereoscopic microscope, autofluorescence method, histological method and computed microtomography. A detailed macro- and micro-structural description of V. komodoensis mandibular teeth were made. The mandibular teeth are laterally flattened along their entire length and the dental crown is hooked caudally. The part of the nasal margin of the tooth crown is irregular, while the caudal margin of the tooth is characteristically serrated, except for the tooth base area. There are longitudinal grooves on the lingual and vestibular surfaces up to the lower third of the tooth height. The mandibular tooth is surrounded by a cuff made of the oral mucosa, containing the opening of the venom gland. In the histological structure of the tooth, the enamel covering the tooth crow...

The occurrence and manifestation of each ameloblastic fibro-odontoma (AFO) is quite rare and uncommon. Mentioned odontogenic tumor classification had changed over the years; however, the treatment possibilities for this lesion remain the same. In most cases surgical enucleation is sufficient enough; however, bigger lesions might require bone curettage with sometimes performed bony ostectomy, which is a quite sufficient and effective method of treatment. In the presented case report, a panoramic radiological evaluation indicated an impacted molar tooth surrounded with mixed radiolucent/radiopaque areas. The 10-year-old Caucasian girl was scheduled for an incisional biopsy. The bone cavity in the mandible after tumor removal might be left for spontaneous healing or grafting techniques, depending on the shape and size of the defect. In the presented case report, the usage of PRF/iPRF in the mandibular bone cavity, and healing improved the overall final result.

Nowadays, maxillo-facial surgery procedures are greatly dependent on good general anesthesia and adequate maintenance care of the airways. Nasotracheal intubation (NTI) is one of the most common ones, especially in orthognathic surgery, temporomandibular joint-related surgeries, or others. Nasotracheal intubation itself is not a problem; however, maintaining its stable and safe position, regardless of the excess of surgical maneuvers in the facial skeleton, is important. There are a lot of techniques, personal modifications, and materials used to support tube placement. It is quite common that either plaster or a bandage roll can be useful with a combination of various forms of sponges or wipes in different shapes, sizes, and elasticity to support the tube’s adequate position, especially when maintaining a good shape and position of the nose and symmetry line and avoiding unnecessary tube flexion. In the following paper, one of the tube support alternatives with an anti-bedsore heel...

In order to fully evaluate and establish the degree of bone overgrowth, various radiological studies are essential in the careful planning of the amount of surgical excision. In the presented paper, the authors use self-designed anatomo-topographical reference points for planning the surgeries. Routine panoramic radiographs and low-dose computed tomography based on anatomical landmarks help in measuring the proportions of mandibular bone overgrowth with the following preoperative anatomical landmarks: (Go-Go), (Go(Right)-Gn), (Go(Left)-Gn), and (Me–Gn). Measurements taken at selected points and landmarks (gonion-gnathion/gnathion-menton) are easy to conduct. In the authors’ proposal, the main key factor is total chin correction, which is necessary in cases of severe overgrowth; when F0 > C and Go-Gn>, there is >7 mm of vertical bone overgrowth, and the mandibular canal is positioned <5 mm from the inferior mandibular border—MIB. Larger overgrowths (>7 mm) have a great...

Simple Summary The present study aimed to determine the possibility of limiting potential dioxin disorders of the structure of hard tissues in the offspring of intoxicated rat mothers by simultaneous administration of α-tocopherol (vitamin E) or acetylsalicylic acid (ASA). The levels of magnesium (Mg), calcium (Ca) and phosphorus (P) contained in bone tissue as indicators of the process of mineralization of hard tissues were also determined. The chaps were harvested from the offspring of eight female Buffalo rats for testing. Selected morphological, chemical and physical parameters of the teeth of the offspring of female rats from the experimental groups were analyzed. The analysis showed the effect of vitamin E and ASA for the content of Mg, Ca and P. In combination with 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), vitamin E and ASA, they positively inhibit the inflammatory process, preventing the leaching of Ca and Mg from the bones. ASA counteracted this phenomenon much more effec...

Horse withers height is frequently estimated based on skeletal remains during archeozoological analyses. The routinely used methods (Vitt and Kiesewalter) do not allow withers height estimation without complete long bone and skull osteometry. The modified Wyrost and Kucharczyk formula is based on the internal dimensions of the cranial cavity. This method can be used even when the neurocranium is the only surviving portion of the skull. Earlier investigation demonstrated that it can be used as a substitute for the Kiesewalter method. The statistical analyses of the results achieved using metapodial bones are strongly correlated with the results achieved using the Wyrost and Kucharczyk method. A unique horse skull assemblage, dating back to medieval times, was unearthed from several archeological sites in Poland (Silesia, Kuyavia, Grater Poland, Western Pomerania, and Eastern Pomerania). This study aimed to estimate the withers height of this assemblage using the modified Wyrost and K...

The study was carried out on 10 swine of 20-30 kg body weight. Five animals were assigned to each of 2 groups. An aneurysm of the abdominal aorta was created experimentally in animals from the first and second study group. After 4 weeks, animals from the second group were subject to aneurysm repair using an aortic prosthesis. During the experiment, we measured the myoelectric activity of the muscular layer of the abdominal aorta and aneurysmal lesion with the ultrasonographic technique. Measurements of the aorta and aneurysmal lesion and histopathological analyses were carried out post-mortem. We found a statistically significant decrease in the myoelectric activity of the aorta on the aorta-straight prosthesis interface and a significant decrease in the thickness of the muscular layer of the aorta on the aorta-prosthesis interface. No similar changes were found for experimentally induced aneurysms of the abdominal aorta. A straight prosthesis graft may not be the perfect option in ...

Investigation of the effect of α1-adrenergic receptor subtypes on the contraction of the abdominal aorta will allow for more effective treatment of hypertension by use of selective antagonists. The aim of the study was to evaluate the participation of α1-adrenergic receptor subtypes in the contractility of the aortic smooth muscle cells in rabbits. The in vitro experiments were performed in isolated tissue preparations from 30 adult female New Zealand rabbits. The abdominal aortic sections were placed in organ bath chambers and contracted with increasing doses of non-selective α1-adrenergic receptor agonist phenylephrine without pre-incubation or after incubation in α1-adrenergic receptor subtype-selective or non-selective antagonists. Separate sections were incubated with increasing concentrations of antagonists. Phenylephrine caused maximal rise in arterial smooth muscle tone to 4.75 ± 0.47 mN. The most potent in blocking phenylephrine induced contraction was 5-metylurapidil (α1A-...

The aim of the study was to evaluate electrical properties of the mammary gland of dairy cow during manual and mechanical milking and to adapt the electrographic method for analysis of udder physiology. Udder myoelectrical activity was measured on 10 healthy highly productive dairy cows of Slovak Pied cattle breed. The electrical activity of four quarters of the udder was recorded simultaneously using four bipolar electrodes. The udder was stimulated by delicate two-finger massage, manual milking and mechanical milking. During the experiment the duration of the reaction for stimulation and the amplitude of spike dischargers were listed. The udder stimulation through palpational massage of the teat end, manual and mechanical milking caused immediate reaction. The udder responded to stimulation with an increase in myoelectrical activity: increase in discharge frequency to 2.33 ± 0.6 per min and an increase in discharge amplitude with the average of 457 ± 147 µV. The average count of s...

Knowledge about horses from early medieval (10th–13th c.) Poland has been largely based on historical and archaeological data. Archaeozoological information has only been used to a limited extent. Therefore, this article aims to present the current state of knowledge on this subject, drawing on archaeozoological data from studies of horse bones. Apart from confirming earlier reflections regarding the sacred significance of the horse, additional information was obtained about specific individuals who were the subject of magical treatments. It turned out that sites with horse skeletons and skulls are few compared to the familiar presence of horse remains among kitchen waste. This contrasts with the neighbouring regions, where horses were buried more frequently among the Germans, Scandinavians and Prussians. Some new data have been obtained thanks to taphonomic analyses, which demonstrated that horse skulls of apotropaic status were not only exposed to public viewing but were also depo...

This study aimed to evaluate the impact of single and triple administration of levamisole on the dynamics of hematological parameters during experimental pleuritis. The experiment was performed on female Buffalo rats. Rats were randomly assigned to two equal groups that received 1 and 3 doses of levamisole every 2, 24 and 48 h, respectively. Following the experiment, blood samples for the measurement of hematological parameters were collected. The study group receiving three doses of levamisole observed a significant reduction of red blood cell count at 48 h post administration and an increase in mean corpuscular volume compared to the control inflammation group. The administration of a single dose of levamisole results in a significant increase in hematocrit at 72 h, an increase in white blood cell count at 24 h and 72 h, and an increase in neutrophil count at 72 h compared to the control inflammation group. Administration of a single and triple dose of levamisole showed statistica...

A lateral periodontal cyst (LPC) is a rare finding. Patients diagnosed with LPC younger than 40 years of age are not that common. Mostly asymptomatic LPCs can be discovered on routine radiographs as an oval radiolucency between two mandibular premolar teeth roots and can vary in shape and size. Most cases are treated with enucleation, bone curettage, or a combination of both, greatly depending on the surgeon’s preference. Because most LPCs are quite small, lesions do not require any regenerative procedures. In the presented case, because of cortical expansion of the lesion and loss of vital bone bridge surrounding two adjacent maxillary teeth, a guided bone regenerative procedure (GBR) with xenograft bone substitute was used. Despite that small lesions can heal on their own, nowadays the approach of full-mouth therapy (FMT), including direct soft or hard tissue reconstruction in the oral cavity, seems to be a wise treatment. The presented paper presents and describes an unusual LPC ...

The study presents an analysis of a horse skeleton discovered in the timber and earth frame of the rampart surrounding the ducal stronghold in Gda nsk. The body of the animal was deposited sometime from the beginning of the 11th to the mid-12th century. The male horse was aged 8-9 years old and had an estimated withers height of 128 cm (12.6 hands). The dentition and lesions on the skull suggest that the horse was used for riding. Two types of skeletal injuries are visible-the first resulted from the use of the horse and is visible on the skull, teeth, vertebrae, and limb bones. Such bone lesions are described in modern literature on equine medicine; therefore, their aetiology and clinical manifestation are described. The second group of injuries are lesions located in topographically distant areas: the skull, thoracic vertebrae, ribs, and limb bones. Their common feature is a proliferative periosteal reaction. Their aetiology cannot be definitely stated on the basis of the available material. They may be considered an effect of mechanical load-bearing resulting from the excessive use of the horse but also may reflect a generalized infection.

Healing of osteoporotic defects is challenging and requires innovative approaches to elicit molecular mechanisms promoting osteoblasts-osteoclasts coupling and bone homeostasis. Cytocompatibility and biocompatibility of previously characterised nanocomposites, i.e Ca5(PO4)3OH/Fe3O4 (later called nHAp/IO) functionalised with microRNAs (nHAp/IO@miR-21/124) was tested. In vitro studies were performed using a direct co-culture system of MC3T3-E1 pre-osteoblast and 4B12 pre-osteoclasts. The analysis included determination of nanocomposite influence on cultures morphology (confocal imaging), viability and metabolic activity (Alamar Blue assay). Pro-osteogenic signals were identified at mRNA, miRNA and protein level with RT-qPCR, Western blotting and immunocytochemistry. Biocompatibility of biomaterials was tested using bilateral cranial defect performed on a senescence-accelerated mouse model, ie SAM/P6 and Balb/c.

This paper considers the observation of pathological changes in animal skeletal remains from four archaeological sites in Sirmium and one rustic villa (Vranj) located near the city. Before the pathological analysis, skeletal elements, as well as insight of taxonomic and age of animals were determined. 13599 bones or bone fragments were examined. In 72 specimens various abnormal changes have been observed. Most of the pathological changes were present in skeletal remains of cattle and horses. Macroscopic and radiographic analysis of pathological changes in the animal bones established that the lesions had proliferative and chronic character. Proliferative changes in the bones of cattle and horses indicate that these animals were used as draught animals and/or carrying cargo. Considering that most of the horses skeletal remains are from the Hippodrome, it is very possible

Caričin Grad is located in southern Serbia, on the eastern slopes of the Radan Mountain, 30 km southwest of Leskovac. The remains of Caričin Grad are associated with the important Early Byzantine city Justiniana Prima, founded ex nihilo in the AD 530s by the emperor Justinian I (527– 565), in order to perpetuate his birthplace. Situated in a rural area in the western part of the province of Dacia Mediterranea, the city presents a unique example of late urbanisation in the northern provinces of Illyricum. Since it lasted for a very short time – only 80 years – and the area has remained uninhabited until today, the site has yielded well-preserved monuments and remains of material culture. Animal bones showing pathological changes come from three locations in the city: the complex of the south-eastern corner tower of the Lower town, the intramural housing in the Lower town and the intramural housing in the Upper town. The main part of the material originated from occupation layers dated to the second half of the 6th century. This paper presents the analysis of animal remains with pathological changes from Caričin Grad, discussing their significance for economy and social status in Justinia Prima.

Hemimandibular hyperplasia (HH) and elongation (HE) are the most common pathologies present in the mandible. Presented condylar hyperplasias have their own radiological and clinical features. In most cases, patients suffer from various forms of malocclusion. From a total of 150 asymmetrical jaw radiographs evaluated, 46 were evaluated and included in this study. A retrospective study on the data of 46 selected patients treated, diagnosed, and consulted from various forms of mandibular and skeletal asymmetry based on routine diagnostic panoramic radiographs evaluated typical and atypical radiological and anatomical symptoms of condylar hyperplasia. The presented evaluation focused on mandibular, maxillary, and other bones, in order to distinguish condylar hyperplasia from other forms of mandibular asymmetry. The degree of maxillary downward growth followed by the occurrence of an open bite on the affected side estimate the degree/presence or cessation of growth in the affected condyl...

Background: Linen dressings were invented a few years ago but are still being worked on. Methods: The obtained fabrics from the traditional variety of flax (Nike), two transgenic types of flax (M50 and B14) and the combination of these two flax fibers (M50 + B14) were tested in direct contact in cell cultures. Cell viability tests were performed, and the proliferation potential of cells on Balb3T3 and NHEK cell lines was checked using the Sulforhodamine-B (SRB) test. Moreover, the effect of new linen fabrics on apoptosis of THP-1 cells, as well as on the cell cycle of NHEK, HMCEV and THP-1, cells after 24 h of incubation was assessed. Results: All tested linen fabrics did not raise the number of necrotic cells. The tested fabrics caused a statistically significant decrease in the total protein content in skin cancer (except for 0.5 cm of Nike-type fabrics).

Background: The aim of this study was to evaluate the usefulness of a thulium-doped fiber laser and a diode laser in zero ischemia kidney surgery, by carrying out a comparative study in a pig model. Material and methods: Research was carried out on 12 pigs weighing 30 kg each. A thulium-doped fiber laser (TDFL) and a diode laser (DL) operating at wavelengths of 1940 and 1470 nm, respectively, were used. The cut sites were assessed both macroscopically and microscopically. The zone of thermal damage visible in the histopathological preparations was divided into superficial and total areas. Results: During partial nephrectomy, moderate to minimal bleeding was observed, which did not require additional hemostatic measures. All animals survived the procedure. On day 0, the total thermal damage depth was 837.8 µm for the TDFL and 1175.0 µm for the DL. On day 7, the depths were 1556.2 and 2301.7 µm, respectively. On day 14, the overall thermal damage depth for the DL was the greatest (680...

The ergonomics of transport is a topic widely described in the literature. One of the fields of ergonomics that researchers are engaged in is vibrometry (both laser and accelerometry) of travel and its translation into NVH (Noise, Vibration and Harshness). However, so far, the influence of baby carriage movement on the generated vibrations has not been described in more detail. The topic seems to be particularly important considering occurrence of vibrations with significant amplitudes, whose frequency range can have a direct bearing on the resonance frequencies of the child’s internal organs. The article presents the results of research consisting in the measurement of vibrations to which an infant, lying in two different types of prams, may be exposed when being transported on different surfaces. The author’s measurement system, based on accelerometry, was used for the research. The obtained weighted RMS acceleration values not only exceeded human comfort level in all cases (accor...

During pre-operation planning, an implantologist has to decide about the location of a dental implant based on the available bone, anatomical structures and future prosthetics. The aim of this study was to provide an overview of the configurations of the junction zone of the pterygoid process, maxillary tuberosity and pyramidal process among the population and to determine the usefulness of 3D model visualization in regard to precision of anatomical structure projections for clinical planning. A total of 72 cases were analyzed for seven measurements (lateral, medial, rostral, caudal, area, line-1 longitudinal, line-2 transverse) on both body sides—right (R) and left (L). In 57 cases, age and sex of the patient were given. In 15 cases this information was missing. Among the group of 57 cases with complete data, there were 30 females (F) and 27 males (M). A total of 57 models of upper jaws including the adjacent pterygoid process of the sphenoid bone were taken for investigation. The ...
