Brief summary: Molar incisor hypomineralization (MIH) is a developmental defect of enamel affecting the first permanent molar and frequently the incisors with a prevalence of 16-16.9% in Malaysia. They presented with many problems such as hypersensitivity, increase susceptibility of caries, need for recurrent complex dental treatment, and difficulty to achieve pain control. Silver Diamine Fluoride is a new form of topical fluoride that has been extensively used and recommended for the management of caries in children and adolescents. The influence of organic material removal from artificial dentine lesions by means of surface pre-treatment with deproteinizing agent show favoring result of its use on subsequent remineralization with and without fluoride. The purpose of this trial is to study the clinical outcome of SDF and papain based gel on hypomineralized teeth restored with HVGIC.

Detailed description: This is a three-arm parallel randomized controlled trial and will be performed in participants between the age of 5 to 15 years presented with hypomineralised molar of MIH in origin.

Clinical assessment, radiograph, and photographs will be taken for assessment. Patients that fulfilled the inclusion criteria will be invited to the study. After that, the patient will be explained and a Patient Information Sheet (PIS) will be given. Once consent obtained and the patient randomly allocated for the treatment group, treatment will be done as below:

For group 1, any caries if present will be removed using a hand instrument. The tooth then will be filled with High Viscous Glass Ionomer Cement (HVGIC) following the manufacturer's instruction. If the participant is assigned to group 2, after caries has been removed using a hand instrument, silver diamine fluoride (SDF) will be applied for 1 minute on the affected area prior to restoration with HVGIC following the manufacturer's instruction. If the participant is assigned to group 3, papain-based gel (Papacare Duo) will be applied as a deproteinizing agent, caries will be removed using a hand instrument if present. Then, silver diamine fluoride will be applied for 1 minute on the affected area prior to restoration with HVGIC following the manufacturer's instruction.

The patient will be followed up after 6 and 12 months. The teeth and restoration will be assessed clinically by an assessor that is not involved in the provision of treatment. Sign and symptom of pain, tenderness to percussion, presence of swelling or fistula, the scale of sensitivity using Schiff Cold Air Sensitivity Scale (SCASS), quality if restorative assessment using Atraumatic Restorative Treatment (ART) Index
