Molar incisor hypomineralisation
Conditions
Interventions
The participants will be divided in three groups based on the researcher view that resin infiltration alone should improve the aesthetic appearance of their incisors. OR would benefit from bleaching a

DMG, Hamburg, Germany) will be applied to the lesion for 120 s, the tooth washed for 30 s using triplex water spray
ethanol applied for 30 s to desiccate the lesion (Icon Dry

| To evaluate the impact of this condition on oral health quality-of-life (OHQoL), using the Parental-caregiver perceptions of child OHQoL P-CPQ (for ages 6 to 14 years; Jokovic et al., 2003, Peruvian Spanish version 2013) This questionnaire has 31 items divided into four sub-scales: oral symptoms (6 items), functional limitations (8 items), emotional wellbeing (7 items) and social wellbeing (10 items). A five-point Likert scale will be used, 0 – never; 1 - once/twice; 2 – sometimes; 3 – often; 4 - every day/almost every day. For the 31 items, the final score ranges from 0 to 124, for which a higher score will indicate a greater degree of the impact of oral conditions on quality of life of the child. (Jokovic et al., 2003, Peruvian Spanish version 2013) [it will be measured before treatment, one week, one month and 3 months after treatment] Participant and parental/guardian direct visual perception of the lesions will be measured using the Extended Visual Rating Scale for Appearance Match (EVRSAM) Rating Scale. (Ostervemb 2011) [Before, immediately after treatment and 1 and 3 months later] Digital photographic images will be taken under standardised camera and lighting settings. These images will be inspected and rated by a panel consisting of four dentists (two specialist paediatric dentists with experience in MIH (including the student researcher), one general dentist with experience in MIH, one paediatric postgraduate student in training (with limited experience in MIH) and one layperson with no dental training or MIH experience. The examiners, blinded regarding the timepoint at which the image was taken and whether the teeth were bleached before resin infiltration, will grade aesthetic appearance according to EVRSAM. The three images of the treated tooth will be displayed side-by-side in a single Powerpoint® (Microsoft Inc., WA, USA) slide, in randomised order, under standardised lighting and screen brightness settings. Tooth images will be graded using the | — |
