Anethesia Efficacy on Teeth With MIH (Molar Incisor Hypomineralisation)

Kocaeli University70 enrolled

Overview

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

Interventions

PhotobiomodulationPROCEDURE

In experimental groups, before topical anesthesia, PBMT was applied by utilizing a diode laser (EpiX; Biolase technology, inc., USA) with a continuous wavelength of 940 nm on a 400-μm fiber with only biostimulation properties. In accordance with the recommendations of the device's manufacturer, it was applied using circular motions in a manner as slowly as possible (an average of 33-36 circular movements in 60 s)

PlaceboPROCEDURE

In the control group (placebo), the laser probe was directed to the mucosa for (buccal and palatal area), but not activated, and the sound of the laser device previously recorded on the mobile telephone was played for the same time of experimental group in order to provide similar conditions

Outcomes

Primary Outcomes

Evaluating efficacy of anesthesia with using the Face, Legs, Activity, Cry, Consolability (FLACC) Scale

Anesthesia efficacy was evaluated objectively with the FLACC scale during the cavity preparation. Behavioral parameters were recorded during the cavity preparation (dentin cutting handpiece ) FLACC scale comprises of five sub-parameters. They are Face, Legs, Activity, Crying and Consolability. Each sub-parameter is given a pain score of 0 to 2. So total behavioral pain score range 0-10 as follows: 0 = relaxed and comfortable (no pain); 1-3= mild discomfort; 4-6 = moderate pain; and 7-10 = severe discomfort and/or pain. Success was achieved if patients experienced mild pain or no pain during the preparation of the cavity

Time frame: Through study completion, an average of 24 weeks

Evaluating need of supplementary anesthesia

The subjects with moderate/higher pain need supplementary anesthesia
