The aim was to report the use low-level laser therapy (LLLT) in the management of hypersensitivity in an adolescent with molar incisor hypomineralization (MIH) and the impact of LLLT on his oral health-related quality of life (OHRQoL). Clinical examination revealed severe MIH with hypersensitivity, in all first permanent molars and incisors. The treatment proposed was desensitization with fluoride and esthetic rehabilitation of the affected teeth. Then, LLLT was applied perpendicularly in a continuous mode (wavelength of 808 nm, power of 100 mW, dose of 1 J, and fluence of 35 J/cm2). The visual analogue scale was applied each session of LLLT. The child perceptions questionnaire (CPQ11-14) was administered at the beginning and the end of the treatment. It was concluded that LLLT can be indicated in the management of hypersensitivity in an adolescent with severe MIH to control pain and to improve his OHRQoL.
目的在于报告在一名患有磨牙和切牙牙釉质发育不全（MIH）的青少年的管理中使用低水平激光疗法（LLLT）的情况，以及 LLLT 对其口腔健康相关生活质量（OHRQoL）的影响。临床检查显示所有第一恒磨牙和切牙均有严重的 MIH 和过敏症状。提出的治疗方案是用氟化物脱敏和对受影响的牙齿进行美学修复。然后，以连续模式（波长 808nm，功率 100mW，剂量 1J，通量 35J/cm2）垂直应用 LLLT。每次 LLLT 治疗时都使用视觉模拟量表。在治疗开始和结束时，使用儿童感知问卷（CPQ11-14）进行评估。结论是，LLLT 可用于治疗患有严重 MIH 的青少年的过敏症状，以控制疼痛并改善其 OHRQoL。
