- Brief Summary
Introduction: Photobiomodulation (PBM) shows promising results for the complementary treatment of dentin hypersensitivity; however, few studies have evaluated this treatment specifically for teeth affected by molar incisor hypomineralization (MIH). The aim of this study was to assess the effects of photobiomodulation combined with glass ionomer sealant on hypersensitivity in molars with MIH. Methods: Forty-nine children six to twelve years of age with a molar affected by MIH (Grade 3, 4a or 4b) of the MIH-TNI (Treatment Needs Index) criteria were randomly allocated to two groups - Group 1 (control group) (n = 25): toothpaste with fluoride concentration ≥ 1000 ppm (Parts Per Million) twice per day, glass ionomer sealant and simulated PBM; Group 2 (study group) (n = 24): toothpaste with fluoride concentration ≥ 1000 ppm twice per day, glass ionomer sealant and active PBM. Data collection involved the record of MIH, Schiff cold air sensitivity scale (SCASS), visual analog scale (VAS), the simplified oral hygiene index (OHI) and the colour, coverage, caries (CCC) sealant evaluation system. Results: Forty-six children completed the study and were evaluated one month after the onset of treatment. A significant reduction in the Schiff Cold Air Sensitivity Scale (SCASS) was found only in the active PBM group. Reductions in Visual Analog Scale (VAS) scores were observed in both groups, with a statistically significant difference between the groups at the 48-hour and 1-month assessments following PBM application. Similarly, significant differences in the Oral Hygiene Index (OHI) were found only in the active PBM group when comparing baseline values to those after 48 hours and one month. A significant difference between the groups was noted for sealant durability at one month, with better scores in the active PBM group. Conclusion: The administration of photobiomodulation combined with glass ionomer cement improves hypersensitivity and oral hygiene in molars with MIH. The improvement in oral hygiene increases the quantity of remaining sealant on teeth with MIH.

Group Intervention Description Control Group Use of fluoride toothpaste Participants in this group received toothpaste with fluoride concentration ≥ 1000 ppm (Parts Per Million), glass ionomer sealant and simulated low-level laser. Control Group Simulated Laser Therapy Participants in this group received toothpaste with fluoride concentration ≥ 1000 ppm (Parts Per Million), glass ionomer sealant and simulated low-level laser. Control Group Sealant application Participants in this group received toothpaste with fluoride concentration ≥ 1000 ppm (Parts Per Million), glass ionomer sealant and simulated low-level laser. Study Group Use of fluoride toothpaste Participants in this group received toothpaste with fluoride concentration ≥ 1000 ppm (Parts Per Million), glass ionomer sealant and active low-level laser. Study Group Photobiomodulation Participants in this group received toothpaste with fluoride concentration ≥ 1000 ppm (Parts Per Million), glass ionomer sealant and active low-level laser.

- Primary Outcome Measures
Name Time Method Changes in pain - Visual analog scale (VAS) Baseline, 48 hours after the procedures and 1 month after. The perception of pain in children was assessed using the Wong-Baker Faces Pain Rating Scale. This scale facilitates communication, allowing for a more accurate assessment of the pain reported by the child.
Changes in the Schiff Cold Air Sensitivity Scale (SCASS) Baseline, 48 hours after the procedures and 1 month after. The (SCASS) will be used to assess subject response to this stimulus (0=no response to the stimulus; 1=no response to the stimulus, patient considers stimulus to be painful; 2= response to stimulus, patient moves from the stimulus; 3= response to the stimulus, patient moves from the stimulus and requests immediate discontinuation of the stimulus).
- Secondary Outcome Measures
Name Time Method Changes in the Simplified Oral Hygiene Index (Greene and Vermillion) Baseline, 48 hours after the procedures and 1 month after. Analysis of soft plaque deposit:
Code 0 = no deposits or pigmentation Code 1 = deposits covering less than 1/3 or presence of pigmentation Code 2 = deposits covering more than 1/3 but less than 2/3 Code 3 = deposits covering more than 2/3 of tooth surfaceSealant Assessment System Baseline, 48 hours after the procedures and 1 month after. The retention of the sealant was evaluated after 1 month using the CCC Sealant Evaluation System. For statistical purposes, the following classification was considered: A: sealant present; B: Sealant present on 50% of fissure pattern but some missing; C: Sealant present on 50% of fissure pattern.; D: no sealant present.
