Objective:The purpose of the present study was to assess the knowledge of General dentist regarding the management of dental traumatic injuries of primary teeth.Materials and Methods:A total of 100 general dentists were selected and a validated questionnaire was distributed among the dentist to assess their knowledge on treatment strategies regarding traumatized primary teeth.Statistical Analysis:Data were entered into SPSS version 20.0 for percentages. The correct answers were tested in relation to the dentists’ years of experience using the Chi-square test.Results:Analyzing the questionnaire for knowledge, 49% of dentists answered accurately regarding avulsed primary teeth, 36% of dentists answered appropriately regarding crown and root fractures, and 55% of dentists gave appropriate answers regarding luxation injuries. Chi-square test showed a statistically significant difference only for 2 questions in relation to the dentist's years of experience (P < 0.05).Conclusion:There is a lack of consistency in the knowledge among general dentist regarding traumatic dental injuries of primary teeth. There is a need to create awareness and education regarding traumatic injuries of primary teeth.

Objective:In permanent dentition, different rotary systems are used for canal cleaning and shaping. Rotary instrumentation in pediatric dentistry is an emerging concept. A very few studies have compared the efficiency of rotary instrumentation for canal preparation in primary teeth. Hence, this study was performed to compare the obturation quality and instrumentation time of two rotary files systems – Protaper, Mtwo with hand files in primary molars.Materials and Methods:Forty-five primary mandibular molars were randomly allotted to one of the three groups. Instrumentation was done using K-files in Group 1; Protaper in Group 2; and Mtwo in Group 3. Instrumentation time was recorded. The canal filling quality was assessed as underfill, optimal fill, and overfill. Statistical analysis was done using Chi-square, ANOVA, and post hoc Tukey test.Results:No significant difference was observed in the quality of obturation among three groups. Intergroup comparison of the instrumentation time showed a statistically significant difference between the three groups.Conclusion:The use of rotary instrumentation in primary teeth results in marked reduction in the instrumentation time and improves the quality of obturation.

<p><strong>Objective:</strong> Despite the tortuous course of primary root canal system, a paradigm shift occurred from conventional hand files to rotary system, which lead to faster, cost-effective, uniform and predictable fillings. One of the many advantages being, reduction in post-operative pain with the use of rotary system. Many rotary file systems were introduced, with the recent one, the Kedo-S. So the present study aimed to compare and evaluate the post – operative pain after pulpectomy using K-files, MTwo files and Kedo-S files in deciduous molars. <strong>Material and Methods:</strong> 75 teeth were randomly divided into three groups (group A – K-files, group B - Kedo-S files and group C - MTwo files) for pulpectomy of primary molars. Post – operative pain was assessed every 6,12,24,48 and 72 hours using facial pain scale. <strong>Results:</strong> 44% of volunteers in K-file group had moderate pain followed by Kedo-S group that is 8% and then MTwo files that is 4%. <strong>Conclusion:</strong>  The least post-operative pain was found in Mtwo group followed by Kedo-S group and K-file group.</p><p><strong>Keywords</strong></p><p>Pulpectomy; Post-operative pain; MTwo; Kedo-S.</p><p> </p>
