Aim: The aim of this study was to evaluate and compare the efficacy of three types of plaque control methods among 13- to 35-year-old subjects receiving fixed orthodontic treatment in Coorg Institute of Dental Sciences, Virajpet, Coorg district, Karnataka, India. Materials and Methods: A total of 111 subjects who fulfilled the inclusion and exclusion criteria were randomly included in the study. The subjects were recalled after 1 month of the commencement of fixed orthodontic treatment for the recording of baseline data including plaque index (PI), gingival index (GI), and modified papillary bleeding index (MPBI). After recording of the baseline data, the subjects were randomly allocated into each of the intervention groups, i.e., group A (manual tooth brush), group B (powered tooth brush), and group C (manual tooth brush combined with mouthwash) by lottery method. Further, all the subjects were recalled after 1 and 2 months for recording the data. Results: Regarding plaque levels, it was seen that there was a highly statistically significant difference between the three groups (P = 0.001), with the manual tooth brush combined with chlorhexidine mouthwash group recording the lowest mean PI score of 0.5±0.39. A comparison of the mean GI scores among the groups at the end of 2 months shows a highly statistically significant difference (P = 0.001). The mean MPBI scores at the end of 2 months were highly statistically significant among the three groups (P = 0.001), with the group C recording the lowest mean MPBI score of 0.3±0.3. Conclusion: The powered tooth brush group subjects exhibited significantly lesser PI, GI, and MPBI scores than the manual tooth brush group at the end of 2 months, whereas the manual tooth brush combined with chlorhexidine mouth wash group subjects showed maximum improvement, having significantly lesser PI and GI scores than the powered tooth brush group.

Even though orthodontic treatment is indispensable for nearly 16-20% of the whole world population with functional efficiency, structural balance and aesthetic harmony as its main advantages and rationale, the treatment particularly with a range of removable, fixed, functional and extraoralorthopaedic appliances can cause various deleterious hard tissue and soft tissue injuries in particular, intraorally. These intraoral and extra oral hard and soft tissue injuries can be iatrogenic, self-induced, caused by bad patient compliance or just by accidents intervened by the patient while wearing the appliance. These traumas/injuries are not uncommon since an orthodontic treatment are mainly done with stainless steel [metal] and the treatment usually continues for a long period of time ranging from 6- 36 months in themajority of the cases. The high pervasiveness of individuals with dental trauma preceding to orthodontic treatment justify the safety measures that should be followed before a...

Drug-induced gingival overgrowth is frequently associated with three particular drugs: phenytoin, cyclosporin, and nifedipine. As gingival enlargement develops, it affects the normal oral hygiene practice and may interfere with masticatory functions. The awareness in the medical community about this possible side effect of nifedipine is less when compared to the effects of phenytoin and cyclosporin. The frequency of gingival enlargement associated with chronic nifedipine therapy remains controversial. Within the group of patients that develop this unwanted effect, there appears to be variability in the extent and severity of the gingival changes. Although gingival inflammation is considered a primary requisite in their development, few cases with minimal or no plaque induced gingival inflammation have also been reported. A case report of gingival overgrowth induced by nifedipine in a patient with good oral hygiene and its nonsurgical management with drug substitution is discussed in...

AIM The present study aimed to assess the efficacy of different dental varnishes in prevention of demineralization of enamel along the orthodontic brackets. MATERIALS AND METHODS A total of 60 premolars that do not have caries and were extracted for orthodontic purposes were used in this study. Transbond™ Plus was used to bond premolar brackets onto the treated surface of enamel. The teeth were then divided into three groups. Group I: Profluorid varnish, group II: CPP-ACP varnish, and group III: Duraflor™ varnish. A Vickers diamond indenter was used to assess the microhardness of the surface of enamel at baseline, fourth day, and seventh day.

In the last decades, Guide Tissue Regeneration (GTR) technique has been applied for the treatment of various periodontal defects such as intrabony defects, furcation involvements and localized gingival recession defects. From early days of using membranes with the simple aim of minimizing toxic response in the host, membranes have come a long way. Third generation membranes not only act as barriers but also as delivery devices to release specific agents. Many clinical trials have focused on using membranes as delivery devices for antibiotics and growth factors. In this article we take a brief look at the evolution of barrier membranes and future avenues with regard to third generation membranes.

The aim of this study was to evaluate the mechanical properties of the platelet-rich fibrin (PRF) membrane and to compare these properties with that of commercially available collagen membranes used for guided tissue regeneration (GTR) procedures. Scanning electron microscopic (SEM) examination of PRF membrane was also performed to determine the cell distribution pattern within the different regions of the membrane. Modulus of elasticity and hardness of (i) PRF membrane (ii) bovine collagen membrane and (iii) fish collagen membrane were assessed by performing surface indentation test using T1 950 Triboindenter. The in vitro degradation tests were conducted by placing the (i) PRF membrane (ii) bovine collagen membrane and (iii) fish collagen membrane of equal sizes (10 mm × 5 mm) in 5 ml of pH 7.4 phosphate buffer solution on a shaker set at 40 rpm for 1-week. The degradation profiles were expressed as the accumulated weight losses of the membrane. SEM evaluation of the PRF membrane was done under both low and high magnification. Young&amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;amp;#39;s Modulus of elasticity was found to be 0.35 GPa for PRF membrane, 2.74 GPa for bovine collagen membrane and 1.92 GPa for fish collagen. The hardness was 10.67 MPa for PRF membrane, 110.7 MPa for bovine collagen membrane and 90.5 MPa for fish collagen membrane. PRF membrane degraded by about 36% of initial weight after a 1-week in vitro shaking test. Fish collagen membrane degraded by about 8% of initial weight, bovine collagen membrane degraded by about 3% of initial weight. Dense clusters of platelets formed due to extensive aggregation, and few leukocytes were observed in buffy coat area. The preliminary findings from the assessment of the mechanical properties of PRF membrane showed that it was lacking in several desired properties when compared to commercially available collagen membranes. Lack of rigidity and faster degradation may limit its application in GTR procedures.

Introduction Bone removal is necessary for extracting the third molars that are erupted, partially erupted, and/or impacted in bone. Hence, it is necessary to choose a surgical method or instruments that conform to anatomic landmarks and are based on physiological principles. Many authors have reported injuries to the adjacent tooth, especially the distal part of periodontium after removal of second molar. Hence, the present study was undertaken to assess and compare the surgical and postsurgical outcomes of third molar removal using piezoelectric surgery and rotary bur. Materials and methods A total of 30 healthy adult individuals who were in need of prophylactic removal of impacted mandibular third molar tooth with ideal condition were included for the study. Individuals were divided randomly into study groups of 15 each, so that the difficulty of surgery will be the same in both the groups. Group I – piezoelectric osteotomy technique and group II – rotary osteotomy technique. The...
