Present study evaluated the efficacy of laser activation to control intra- and post-operative pain in single-visit root treatment for mandibular molar teeth with acute irreversible pulpitis following 2% lignocaine inferior alveolar nerve block. Ninety-eight patients presenting with pain were randomly divided into two anesthetic groups. Group-I inferior alveolar nerve block plus buccal infiltration and intra-ligamentary injections, Group-II inferior alveolar nerve block followed by laser irradiation focused directly on the pulp tissue. Intra- and post-operative pain intensities were assessed on a 10-point scale.The mean intra-operative pain scores in group-I was 6.62 ± 1.6 and in group-II before and after laser irradiation pain scores was 6.94 ± 2.1 and 1.3 ± 2.04, respectively. Post-operative pain scores at 24-hrs in the laser group were significantly higher. Laser irradiation applied directly on pulp tissue for control of intra-operative pain was effective, thereby negating the need for additional local anesthesia.Clinical relevanceLaser activation was effective method to control intra-operative pain in irreversibly inflamed pulp.Laser irradiation did not cause adverse post-operative pain.

Furcal perforation management in root canal retreatment is often challenging as the outcome of the perforation sealing depends on several parameters. The recent introduction of several bioactive cements and magnification systems has made the sealing of perforations easier and the outcome more predictable. This study highlights the clinical outcomes of furcal perforation management in root canal retreatment using biodentine.

Aim: The primary aim of this clinical trial was to observe the clinical success in conservative management of symptomatic deep proximal caries in permanent molar teeth with two treatment pulpotomy with Biodentine and indirect pulp capping with calcium hydroxide. Materials and Methods: A total of 71 patients who reported to department for the management of symptomatic proximal deep carious lesions in molar teeth participated in the trial. Posttreatment clinical success at 18 months was defined as asymptomatic teeth positively responding to cold pulp sensibility test (only in indirect pulp capping) and absence of periapical infection. Chi-squared test and Kaplan–Meier survival analysis were done. Results: Chi-squared test revealed no significant association between pulp status and posttreatment follow-up in both the treatment groups. Kaplan–Meier survival analysis showed mean survival of pulpotomy procedure for moderate and ambiguous pulp as 66.16 and 67.77 weeks, respectively, with no significant difference for two different pulp statuses. In indirect pulp capping procedure, there was significant difference (P = 0.038) (Log-rank Mantel-Cox) between the two pulp status category with moderate pulpitis having mean survival period of 69.27 weeks and ambiguous pulp with 42.83 weeks. Conclusion: Pulpotomy with Biodentine yielded better results than compared to indirect pulp capping.

This article aims to present about the restorative strategies to be adopted for the management of root canal-treated traumatized maxillary incisors incorporating the contemporary minimal invasive options. Each root canal-treated tooth poses a unique challenge to be addressed in an individual manner. This presentation highlights the restorative assessment and technique to be adopted for restoring the root canal-treated maxillary incisor.
