Material and Method: Thirty-six primary mandibular molars from 4- to 8-year-old children requiring pulpectomy were randomly split into two groups of 18 teeth each, that is, manual file K-file (Group I) and Kedo-S rotary file (Group II). Children’s pre- and postoperative pain was assessed using a four-point scale at different time intervals. Results: From the result of the present study, it was observed that the Kedo-S group showed significantly less pain after 24, 48, and 72 h. Conclusion: It was concluded from the present research that patients enrolled in the Kedo-s group experienced less pain.

Severe facial disfigurement or asymmetry in TMJ ankylosis is very distressing that can cause difficulty in breathing (dyspnoea), eating (dysphagia), speech (dysarticulation) and social reciprocation. Early ankylosis of TMJ in children deteriorates normal mandibular growth. Henceforth, early diagnosis along with immediate surgical intervention and management of TMJ ankylosis should be the necessity of the hour. True ankylosis is osseous or fibrous adhesion between the TMJ surfaces, limited within the articular capsule. Meanwhile, false ankylosis may be caused by conditions not directly related to the joint but due to factors like enlargement of the coronoid process, post surgical scars, irradiation, infection, etc. Formation of a bony mass replacing the articulation is archetypal pathology of TMJ ankylosis ensuing restricted mandibular movements. Consequ...

Rate of abnormal growth of the condyle determines the severity of facial asymmetry causing distress and rarely pain. It has a multifactorial etiology with increased prevalence in females. Two basic growth vectors occur with CH: horizontal growth vector (type 1) and vertical growth vector (type 2). The prevalence ratio between types 1 and 2 is approximately 15:1. Type-1 condylar hyperplasia increases anteroposterior dimension of mandible causing crossbites and Type-2 increases vertical height of mandible causing openbite. Facial asymmetry due to growth disturbances of the mandible mostly requires orthognathic surgical corrections, and asymmetries treated by this method have a high success rate and long-term stability. However, in very severe cases of facial asymmetry associated with condylar hyperplasia (CH), a partial or comple...

Materials and Methods: Sixty children with a treatment plan which included pulp therapy were recruited for the study. Children categorized 3 and 4 of Frankl behavior rating scale and American Society of Anesthesiologists health status I and II were included for the study. Children were distributed into study group (Group-I) and control group (Group-II) by fishbowl randomization. Children in Group-I were induced inhalation sedation using a preadjusted mix of 30% N2O and 70% O2 through rapid induction technique, and children in Group-II were exposed to inhalation sedation by conventional slow induction technique. Parameters such as least oxygen saturation, sedation levels by Richmond Agitation–Sedation Scale, time taken to achieve ideal sedation, maximum N2O concentrations used, and adverse events were recorded and evaluated for each procedure. Data were analyzed using independent sample t-test and Chi-square tests. Results: Analysis of data showed statistically significant difference between both groups in time taken to achieve ideal sedation (P < 0.001). No significant difference was seen in incidence of hypoxia (P < 0.512), maximum N2O concentrations used (P < 0.118), and occurrence of any adverse events. Conclusion: None of the children from both groups exhibited hypoxia. Sense of detachment was seen in one child each from both groups. Rapid induction by preadjusted mix resulted in ideal sedation in 57% children of the Group-I; rest had achieved these levels at 40% N2O. There was a significant difference in the time taken to achieve ideal sedation by rapid induction which was almost half the time taken with slow induction.

Black in early 1900’s. It stressed more on cutting of a healthy tooth structure along with carious tissue in order to provide adequate retention. Nowadays with the increased quality of the restorative materials retention is no longer an issue related to cavity formation. G.J. Mount and W.R. Hume in 1997 proposed a newer classification of carious lesion and cavity preparation which dealt with cutting of only the demineralised carious region. Several techniques like: chemomechanical caries removal, air abrasion, lasers and ozone evolved along with the minimal cavity preparation which was summarised to be known as minimal intervention dentistry or minimal invasive dentistry.

Staphylococcus aureus, Streptococcus viridans, Streptococcus faecalis, Bacteroides melaninogenicus and mixed bacterial culture; obtained from infected non-vital deciduous anterior teeth. The antimicrobial sensitivity was checked on BHI-agar plates using well method. The results showed that all the 4 materials were distinctly different from each other in their antimicrobial activity. Maisto's paste was invariably the superior most in its antibacterial efficacy (in comparison to all the 5 micro-organism strains). Iodoformized zincoxide eugenol appeared to be the second best followed by Kri paste. Vitapex showed the least antibacterial activity.
