Comparing the preventive efficacy of conventional cavity fillings to Silver Diamine Fluoride pretreated cavity filings on adjacent molars in children

INTERVENTION: Intervention1: Silver modified atraumatic restorative treatment: Dentist first removes the decayed and soft tooth structure followed by application of liquid medicine called silver diamine fluoride . The cavity is then filled with restorative material called glass ionomer cement. Total duration for the procedure will be 10‐15 minutes Control Intervention1: Atraumatic restorative treatment: Dentist removes the decayed and soft tooth structure followed by the filling of clean tooth cavity with restorative material called Glass Ionomer Cement.Total duration for the procedure will be 10‐15 minutes CONDITION: Health Condition 1: K026‐ Dental caries on smooth surface PRIMARY OUTCOME: Presence and extent of new carious lesion on the proximal surface of adjacent tooth .Timepoint: Presence and extent of new carious lesion on the proximal surface of adjacent tooth assesed at 6 and 12 months. SECONDARY OUTCOME: 1. Progression or non progression of existing precavitated carious lesions. ; 2. Clinical success of the restoration.Timepoint: 6 month and 12 month INCLUSION CRITERIA: 1. Apparently medically healthy children in the age group 4 to 8 years with frankl behaviour rating scale positive or definitely positive presenting with asymptomatic dentinal cavitated lesion on occlusoproximal surface in at least one primary molar in either maxillary or mandibular arch with no carious lesion or precavitated ICDAS code 1 and 2 lesion in proximal surface of adjacent tooth . 2. Radiographically occlusoproximal caries should not extend beyond the middle third of dentin. 3. Children whose parents have consented to take part in this study and whose parents accept to report for the scheduled followup.
