Background:
Hypersensitivity from Molar Incisor Hypomineralisation (MIH) negatively affects children's oral health-related quality of life (OHRQoL).
Aim:
To evaluate and compare the effectiveness of photobiomodulation (PBM) by low-power laser, resin-based (Fisseal), and glass ionomer (Fuji TRIAGE) sealants on hypersensitivity in children with MIH and their impact on OHRQoL.
Design:
Forty-five children aged 6-10 with one first permanent molar affected by MIH and hypersensitivity were randomly assigned to 3 groups: Group 1 (n = 15) PBM, Group 2 (n = 15) Fuji TRIAGE, and Group 3 (n = 15) Fisseal. Hypersensitivity was assessed before and 15 minutes postintervention, with follow-ups at 1 week, and 1, 3, and 6 months. Pain and sensitivity were measured using the Wong-Baker Faces Pain Rating Scale (FPS) and the Schiff Cold Air Sensitivity Scale (SCASS). OHRQoL was evaluated with the Child Perceptions Questionnaire (CPQ8-10).
Results:
No significant differences in SCASS or FPS scores were found between groups. Significant reductions in SCASS and FPS were observed over time (P < .001), with PBM and Fisseal showing notable FPS improvements at 6 months. All groups showed significant OHRQoL improvements (P < .001), particularly Fisseal.
Conclusion:
Both glass ionomer and resin-based sealants and PBM are effective in reducing hypersensitivity associated with MIH.
Clinical Significance:
PBM is a noninvasive therapy for managing hypersensitivity in children with MIH offering an alternative for apprehensive patients.
