The goal of this clinical trial is to evaluate and compare the short-term effectiveness of two minimally invasive treatments-Atraumatic Restorative Treatment (ART) and Silver-Modified Atraumatic Restorative Treatment (SMART)-in managing dentine caries lesions in the primary molars of children aged 3 to 7 years with Early Childhood Caries (ECC). The main questions it aims to answer are: * Which treatment method (ART or SMART) results in higher clinical success after six months? * How do ART and SMART treatments affect the Oral Health-Related Quality of Life (OHRQoL) of the children? The researcher will compare teeth restored using ART with those treated using SMART (which includes the application of silver diamine fluoride before restoration) to see if one approach leads to better restoration outcomes and to assess how these restorations will impact the quality of life. Participants will: * Receive both types of treatments in different teeth (split-mouth design). * Undergo clinical evaluation of the treated teeth at baseline and six months to assess success based on restoration retention, integrity, and absence of secondary caries. * Have their parents complete a quality-of-life questionnaire (A-ECOHIS) at the start and at the six-month follow-up.

Aim of the Study in details: Primary Aim This study aims to evaluate and compare the clinical outcomes of Silver-Modified Atraumatic Restorative Treatment (SMART) and conventional Atraumatic Restorative Treatment (ART) in the management of carious primary molars in preschool children. This comparison includes: * Success rate: which include restoration integrity, marginal adaptation, absence of secondary caries, and tooth vitality. * Retention rate: Determined by monitoring whether the restoration remains fully or partially retained over time * Caries arrest: where arrested lesions present with hard, darkened surfaces and no progression in lesion size Secondary Aim * To describe the change in oral health-related quality of life of preschool children before and after placement of ART and SMART restorations Randomization The sample size was specified by using the G\* power test, assuming a statistical level of significance of 95% and power of 80% with normal distribution, and effect size calculated from means and standard deviation of 2 groups obtained from a previous similar study (Jiang et al.,2021). The original sample size was 64 molars and was increased up to 80 to avoid any drop out. Eligible molars were randomly and equally assigned to either the SMART or ART group using a randomization software (Random.org). Calibration: One calibrated examiner was responsible for all the dental examinations. The intra-examiner agreement was assessed by re-examining 10% of the sample. The Kappa statistic for intra-examiner reliability was 0.87 which indicates consistency in the application of scoring criteria over the study period. Blinding and Outcome Assessment Follow up assessments were done by the operator at 6 months. Complete blinding was not feasible in some cases particularly where GIC restorations where lost due to noticeable staining of the cavity with SDF. However, blinding of the data analyst was done where all study data was labelled with non-identifying Alphabet letters to reduce risk of bias. Data Collection: At baseline, parents completed a two-part questionnaire: Part 1 gathered general demographic information, while Part 2 included the validated Arabic version of the Early Childhood Oral Health Impact Scale (A-ECOHIS) validated by Farsi et al in 2017\[20\]. At the second follow-up visit. parents completed the same questionnaire again. Statistical Analysis Data were statistically analyzed through SPSS 28 (SPSS IBM statistics, USA). Based on the results of the Shapiro-Wilk test, most of the data were determined to follow a normal distribution. The significance level was set at p ≤ 0.05. Fishers exact test was used to compare the outcomes between ART and SMART at a single time point. Categorical data like the relation between the success rate of both treatments and the type of the cavity was analyzed by using the Chi-Square Test of Independence. Paired Samples t-Test was used to assess the changes in ECOHIS scores at baseline and after intervention.
