About

Difficulty in achieving anesthesia in teeth with molar incisor hypomineralisation (MIH) is a frequently reported clinical problem. The effect of low-level laser on the efficacy of anesthesia in teeth with MIH has not been studied yet. Aim of this study is to evaluate the effect of the Photobiomodulation on the efficacy of anesthesia of maxillary permanent molar teeth with MIH.

Design: The current study was conducted as a prospective, parallel-arm control, randomized, triple-blind clinical trial in children aged between 7to12 years. Maxillary permanent molar teeth with MIH requiring pulpotomy treatment were included. 70 participants were divided randomly into 2 groups as experiment (with PBMT) and control (Placebo) according to the anesthesia technique. In the experimental group, before local infiltration anesthesia was administered, PBMT (a diode laser: 940 nm; continuous mode; 0.5W; 78 J/cm2) was applied perpendicular to the root surface at buccal and palatal area for 60 sec each). In the control group, the laser probe was directed to the mucosa for (buccal and palatal area), but not activated. Evaluation of the pain scores were performed during the access cavity preparation of the pulpotomy treatment using the Face, Legs, Activity, Cry, Consolability (FLACC) Scale. Also, additional anesthesia requirements were assessed for both groups while working on the dentin and pulp
