Analyzing working time and efficient caries removal using a novel bioactive caries detecting dye and air polisher prophy for caries excavation: randomised clinical trial

Abstract

Objectives: This study aims to analyze the working time consumed during caries excavation and pain perception while using a novel Bioactive caries-detecting dye solution (BCD), an Air Polisher Prophy and a combination.

Materials and methods: Four groups (in each group, n = 20 permanent teeth) were selected from 60 people between 17 and 40 years of age. The study included teeth with occlusal dentinal caries in the molars with cavity entrance sizes of less than 2 mm (clinically and radiographically). Randomization software was used to assign patients to various groups. Group A: Conventional Rotary Drilling, Group B: BCD + Mechanical Excavation (Spoon Excavator), Group C: Air Polisher Prophy, and Group D: BCD + Air Polisher Prophy 0.5 mL BCD was applied with a micro brush to the carious tooth surface for 40 s in groups B and D. After that, radiographs were performed to see if the radiopaque extension was visible. For mechanical caries extraction, a spoon excavator was used for group B, and an air polisher prophy was employed for group D. For mechanical caries extraction, a spoon excavator was utilized for group B. An air polisher prophy was employed for group D. Multiple applications of the BCD were used in the event of residual caries. Working time and pain experienced during caries excavation were registered using the Verbal Pain Scale (VPS) (score 0-4), and caries removal was clinically graded using the modified Scale (score 0-5).

Results: The time taken was Group A, Group D, Group B, and Group C, according to statistical analysis using ANOVA and the Post Hoc Test (275.02, 403.8, 461.98, 615.41 s, respectively). Group A had the highest mean VPS (1.85), whereas Group B had the most minor pain (0.6), followed by Group D (1.2) and Group C (0.6). (1.45). Group C (2.35), followed by groups D (1.75), B (1.30), and A (1.30), had ineffective caries eradication (0.90). (p < 0.05).

Conclusions: compared to group C, groups B and D took less time and had less/no pain while excavating caries. Compared to traditional mechanized caries removal methods, the chemo-chemical BCD can diagnose and aid in successful caries removal with minimal pain.

Clinical relevance: The outcomes of the present study demonstrated that the chemo-chemical bioactive caries detecting dye solution has the potential to identify and help in effective caries removal before mechanized caries removal methods.
