Abstract: Background: Restoring an ideal proximal contact in direct Class II composite resin restorations is challenging due to polymerization shrinkage, absence of condensability of composite materials, thickness of matrix bands, and the use of various separation techniques, retainers, and bands. Aims: The aim of this study was to evaluate the proximal contact tightness that is achieved by various matrix systems used to restore a direct Class II cavity with comp… Show more

Context: Sectional matrix systems, namely, Garrison and Bioclear with contact rings, are valuable aids to establish proximal contact tightness and contours in Class II composite restorations when compared with the circumferential matrix system Tofflemire. Aims: This study aimed to compare the proximal contact and contours of Class II restoration in premolars and molars restored with Tofflemire, Garrison, and Bioclear matrix system by FDI criteria of approximal anatomical form using floss or 25-µm metal blade and radiographic examination. Subjects and Methods: Sixty Class II patients were selected, and a preoperative bitewing radiograph was taken. Initially, caries removal was done by round diamond bur, followed by 245 carbide bur. Samples were divided randomly into three groups based on the type of matrix system used for restoration. Group 1 (n = 20): Tofflemire, Group 2 (n = 20): Garrison matrix system, and Group 3 (n = 20): Bioclear matrix system. Matrix systems were applied according to the manufacturer’s instructions, and composite restoration was done. The clinical evaluation of proximal contact and contour was done by a blinded observer immediately after placement of composite restoration using FDI criteria by passing dental floss or 25-µm metal blade, whereas marginal gaps and overhangs were checked using a radiograph. Results were statistically analyzed. Statistical Analysis Used: The statistical analysis was done using the Statistical Package for the Social Sciences (SPSS for Windows, Version 19.0). Descriptive statistics was calculated as frequency and percentage. The comparison of characteristics of the contact points, contour, and radiographic examination was carried out using the Chi-square test. Multiple comparisons were done by comparing column proportions with Bonferroni adjustments. The level of significance for the present study was fixed at P < 0.05. Results: There were significantly higher proportions of normal contacts in Garrison (60%) and Bioclear (70%) compared to that in the Tofflemire (20%) matrix system (Bioclear > Garrison > Tofflemire). Comparison of contours showed normal contours with Garrison (50%), Bioclear (50%), and Tofflemire (15%) matrix system (Bioclear = Garrison > Tofflemire). In radiographic examination, harmonious transitions between the restoration and the tooth were similar in Garrison (30%) and Bioclear (30%) compared to the Tofflemire (15%) matrix system (Bioclear = Garrison > Tofflemire). Conclusions: Garrison and Bioclear sectional matrix systems established superior contacts and contours than the Tofflemire circumferential system.

Aim: This clinical trial aimed to compare the clinical success of coronal pulpotomy and indirect pulp capping (IPC) in managing symptomatic deep proximal caries in molars with moderate pulpitis over a 12-month period. Materials and Methods: A total of 108 vital mature permanent molars with moderate pulpitis were randomly allocated to the IPC (n = 54) or coronal pulpotomy group (n = 54). Dycal and Biodentine were used as pulp-capping materials, followed by composite restoration. The absence of periapical infection and asymptomatic teeth that positively responded to the cold pulp sensitivity test (only in IPC) was considered posttreatment success at 12 months. Data from the study were analyzed using the Chi-square test and Kaplan–Meier survival analysis. Results: There was a statistically significant difference between preoperative symptoms and the cold pulp sensibility test response (P = 0.000), indicating an association between symptoms and pulp sensibility. The average remaining dentine thickness (RDT) value was 0.48 ± 0.5 mm, with no statistically significant difference found between the location of caries and RDT (P = 0.084, P > 0.05). Compared to the IPC group, the pulpotomy group had a greater number of patients at 12 months after treatment that required no intervention. The Kaplan–Meier survival analysis revealed that the mean survival duration for pulpotomy was 48 weeks, and for IPC, it was 42.3 ± 2.35 weeks. Conclusion: Coronal pulpotomy with Biodentine proved more effective in reducing symptoms, achieving radiographic success, and ensuring tooth survival compared to IPC with calcium hydroxide.
