RESUMO

OBJECTIVE: Pediatric endodontics has witnessed many advances in recent years, thus facilitating a faster and efficient treatment option in root canal therapy in children. This in vitro evaluation aims to determine the amount of dentin removal in primary mandibular first and second molars instrumented with hand and rotary files using cone-beam computed tomography (CBCT). MATERIALS AND METHOD: Sixty primary mandibular molars were divided into two groups: Group I was prepared by manual instrumentation using K-type files and Group II was prepared with rotary instrumentation using 0.04 Hero Shaper Classics. Both these groups were further divided into two subgroups, namely (a) primary mandibular first molar and (b) primary mandibular second molar. All the root canals were prepared up to size 30 using the stepback technique. They were mounted on silicone-based impression material and subjected to CBCT scans for the evaluation of dentin removal before and after instrumentation. Dentin removal was calculated by superimposing images using the InVivo 5.1 Anatomage software. Data were statistically analyzed using independent samples t- test. RESULTS: An average amount of dentin removed was found to be significantly higher in manual instrumentation compared to rotary instrumentation in both primary mandibular first and second molars (P < 0.001). CONCLUSIONS: Rotary technique serves as an efficient alternative to the traditional manual instrumentation by overcoming its shortcomings in terms of conservation of the remaining dentin thickness and the time required for its preparation.

RESUMO

This narrative aims at reviewing the available literature for mineral trioxide aggregate (MTA) pulpotomy to understand the procedure better and eventually improve the clinical and radiographic outcomes. An electronic search was conducted in PubMed, Cochrane, ScienceDirect and ClinicalKey databases with the following keywords: MTA pulpotomy, clinical outcomes, radiographic outcomes, primary teeth. No specific inclusion or exclusion criteria were applied as to what articles would be included in this review. The time period for the search began from 2001 with respect to MTA pulpotomy. However, this was not restrictive during the search. MTA pulpotomy has been a successful treatment modality in primary molars with proven success over the years. There is limited literature to support its success in primary incisors.
