Abstract
OBJECTIVE: This multicenter randomized controlled clinical trial aimed to compare the outcomes of stepwise excavation (SW) and partial caries removal (PCR) regarding the maintenance of pulp vitality in deep caries lesions over 5 years. METHODS: At baseline, 299 permanent molars with deep caries lesions were randomly assigned to control or test groups. The control group received the stepwise excavation treatment (SW), while the test group received partial caries removal from the pulpal wall followed by restoration in a single session (PCR). Treatments were conducted in two centers located in the cities of Porto Alegre (South Brazil) and Brasília (Midwest Brazil). Survival analysis was performed to compare PCR and SW over time (Weibull regression models). The primary outcome of this study was pulp vitality, determined by the combination of the following characteristics: positive response to cold test, negative response to percussion, absence of spontaneous pain, and absence of periapical lesion (radiographic examination). RESULTS: This 5-year study includes data pertaining to 229 teeth: 121 teeth actually examined at the 5-year appointment, and 108 teeth contributed with data collected in previous follow-ups (18 months or 3 years). Survival analysis showed success rates of 80% in PCR group and 56% in SW group (p < 0.001). Failure was significantly associated with treatment [PCR, HR=0.38; 95%CI=0.23-0.63)] and region [South, HR=2.22; 95%CI=1.21-4.08]. CONCLUSION: PCR significantly reduced the occurrence of pulp necrosis when compared with SW. CLINICAL RELEVANCE: This study supports the PCR as a single-visit technique to manage deep caries lesions in permanent teeth.
