Detaljert beskrivelse

Thirty patients ranging in age from 20 to 35 years will be enrolled into the study. This study will be designed as a randomized controlled clinical trial including patients requiring six Class I restorations. Participants will be randomly allocated into six groups according to the type of dentin replacement material used: Group I (Biodentin), Group II (Activa Bioactive), Group III (Glass ionomer cement), Group IV (Ever x posterior), and Group V (Flowable resin). Restorations will be placed following standardized cavity preparation and manufacturer instructions. Clinical evaluation will be performed at baseline and 6, 12, and 18 months using modified FDI criteria, assessing retention, marginal integrity, surface roughness, anatomical form, postoperative sensitivity, and secondary caries. Data will be collected and statistically analyzed

Tiltaksbeskrivelse
Tidsramme
marginal adaptation
Tidsramme: 18 months
Clinical evaluation of marginal adaptation was conducted in accordance with the World Dental Federation (FDI) criteria by two calibrated examiners at baseline and after 6, 12, and 18 months. Each restoration was assessed and categorized according to the degree of conformity with the established criteria as follows: score 1, clinically excellent; scores 2 and 3, clinically satisfactory; and scores 4 and 5, clinically inadequate. Scores of 1-3 were considered indicative of clinical success, whereas scores of 4 or 5 were considered indicative of failure. Visual assessment was performed under adequate illumination using a high-intensity light source and a dental magnifying loupe to facilitate accurate evaluation. For statistical analysis, the Friedman test was used to assess within-group changes in restoration outcomes across the different follow-up periods. The Kruskal-Wallis test was applied to compare restoration outcomes among the different groups at each corresponding follow-up.
