Aim: To evaluate and compare the clinical outcomes of Cention-N (CN) and stainless steel crowns (SSCs) as restorations for pulpotomised primary molars, and to study clinical and radiographic outcomes of pulpotomies restored with these materials. Methods: The study was conducted on 60 pulpotomised molars with occlusoproximal caries. These were randomly divided into two groups and restored with either stainless steel crowns or Cention-N. Clinical performance of restorations and clinical and radiographic success of pulpotomy was examined at 6, 9 and 12 months. Results: The mean scores for marginal integrity deteriorated significantly at 6, 9 and 12 months in both groups but in comparison were insignificant. The mean for proximal contact deteriorated significantly for the Cention-N group, whereas the mean for gingival health deteriorated remarkably for the stainless steel crown group at successive evaluations. No tooth in either group showed secondary caries or discomfort on biting, except for one tooth in Cention-N group which presented with secondary caries. The clinical success rate for pulpotomised molars was 100% for both groups until nine months, although this had reduced by the end of 12 months. Radiographically, the success rate was 79.3% for Cention-N, while it was 86.6% for stainless steel crowns at 12 months. There was no significant difference in clinical and radiographic success between either group. Conclusion: Cention-N and stainless steel crowns are comparable for marginal integrity. However, crowns maintain significantly better proximal contacts while Cention-N was notably better for gingival health of the restored tooth. Both materials do not show secondary caries and discomfort on biting and are comparable in clinical and radiographic success of pulpotomy at the end of one year.

Background: This study was done to evaluate the applicability of the Tanaka-Johnston method of prediction of mesiodistal widths of permanent canines and premolars in North Indian population. Methods: 202 dental casts were obtained and mesiodistal widths of permanent lower incisors, canines and premolars were recorded using vernier calipers to nearest of 0.02mm. The predicted values of mesiodistal widths of permanent canines and premolars were obtained using Tanaka Johnston method. These values were put to statistical evaluation using Student't' test and Pearson's coefficient of correlation. Results: The results revealed that the differences between the actual and predicted values of permanent canines and premolars were statistically significant in maxilla and mandible in both sexes. Conclusion: The present study suggests that Tanaka Johnston mixed dentition analysis overpredicted the mesiodistal dimension of unerupted premolars and canines in both male and female subjects and tooth dimension show sexual dimorphism with males having larger mesiodistal tooth dimensions than female

Background: Lead accumulations have been found in teeth and related to behavior deficits in children, but there is a dearth of studies in exploring the role of zinc and manganese dysregulations in autism spectrum disorders (ASD) using the primary tooth as biomarker. Aims: The objectives of the study were to evaluate and compare the concentrations of zinc and manganese in the primary teeth serving as biomarker, in typically developing children and children with ASD. Settings and Design: Twelve primary incisors indicated for extraction were collected from children between the age group 6 and 9 years, for the study. Six primary incisors were obtained from children who had been diagnosed with ASD (study group). The other six teeth were obtained from typically developing children, in the similar age group. Methods: The primary incisors obtained were analyzed for metal concentrations using the technique Inductively Coupled Plasma Optical Emission Spectrometry. Statistical Analysis: This study was statistically analyzed by student's t-test. Results: It was observed that there are significant differences in metal concentrations found between tooth samples of ASD children and typically developing children. Zinc concentrations were double and manganese concentrations were three times, in teeth of ASD children group as compared to the children in the control group. Conclusions: Results of the current study indicate that there are considerable differences in concentrations of zinc and manganese between the two groups and support the contention that there might be an association between metal exposures of a pregnant mother and child during early years of childhood and incidence of ASD.

Aim: To Compare patient and parental preference between nitrous oxide sedation and conventional behaviour management technique for dental treatment. Material and Methods: This cross-over split mouth study design was performed on 30 children (6-12 years old) who require a bilateral treatment involving inferior alveolar nerve block. 15 children were enrolled in a group A & 15 children in a group B. Thereafter, the outcome of preference of technique was assessed by parent and child after both techniques were performed. Results: The collected data was statistically analysed. The majority of children and parents preferred nitrous oxide inhalation sedation to conventional behaviour management techniques. Conclusion: Study concludes that nitrous oxide was preferred by both children and their parents over conventional behavior management techniques.
