Aims: Aim is to evaluate the clinical and radiographic outcome of Intentional Replantation of teeth utilizing Atraumatic extraction technique and Biodentin as root end restorative material Materials and Methods: Any patients irrespective of age & sex who reported to the Department of Conservative Dentistry & Endodontics, D. J. College of Dental Sciences & Research with the post endodontic treatment periapical pathology where orthograde retreatment and apical surgery was unfeasible or declined by patients and where extraction be the last resort was selected for the procedure. Informed consent was taken. Retention and healed status without complications (periapical radiolucency, external root resorption, ankylosis, signs/symptoms, probing <6 mm) was recorded and analyzed with Kaplan-Meier survival analysis and Cox proportional hazard regression model (P < .05). Bivariate associations of the investigated variables with the main complications (ankylosis, periapical radiolucency, external root resorption) evaluated.  Results: Cumulative healed rates from 60% at 6 months to 92% at 12months seen. Complications leading to extraction observed in 1 of 15 attending teeth. The Kaplan-Meier survival function suggested an expected 1-year cumulative retention rate of 92%. Among the 15 teeth, 1 tooth with complication was due to persistent periapical radiolucency and mobility. Null hypothesis was that IR is to preserve the natural dentition, there by upholding the main goal of Conservative treatment. Conclusions: Within the limitations of this study, after analyzing the results and obtaining a complete follow up of 12 months radiographically and clinically, it can be concluded that Intentional replantation is an alternative treatment and should be included in the savior procedures as it has shown a success rate of 92%.

Objective: To assess primary molars early loss in mixed dentition prevalence. Method: A study was carried out in children aged 6 to 12 years. Deciduous molar loss was considered early when it occurred before Nolla stage 6 (full formed crown) of the permanent successor or one year before its physiological exfoliation. Periapical radiographs were obtained to verify the presence of the permanent successor and the level of root formation, as well as the need for placement of fixed space maintainer lingual arch or Nance button. For the study of frequency distribution of early dental loss in relation to gender and dentition, we used the Chi-square test of 5% probability level and the non-parametric Mann-Whitney test for adequate statistical analysis. Results: Of the 315 children examined, 159 (50.47%) were male and 156 (49.52%) were female. Only 25 (7.9%) presented multiple dental losses in the posterior region, 19 in the lower arch and 6 in the upper arch. In the inferior one there was predominance of first and second deciduous molars loss. There was no difference in the association between genders and the occurrence of multiple dental losses (χ² (1) = 0.03, p>0.05). Conclusion: The prevalence of deciduous teeth premature loss was of 7.9% and the most affected teeth were the first and second molars in the lower arch. Lingual arch space holders were installed in 6 children, who will remain with it until the permanent successors erupt into the oral cavity.
