SO SÁNH MỨC ĐỘ ĐAU SAU ĐIỀU TRỊ NỘI NHA TRÊN RĂNG CÓ SANG THƯƠNG QUANH CHÓP VỚI BIOROOT™ RCS VÀ AH PLUS®

Abstract

Objectives: To compare the levels of spontaneous pain and pain on biting after root canal obturation with either a calcium silicate-based sealer (BioRoot™ RCS) or a resin-based sealer (AH Plus®) at 6, 12, 24, and 72 hours post-obturation. Subject and methods: This was a randomized controlled clinical trial conducted on 40 single-rooted teeth from 32 patients diagnosed with periapical lesions. The patients were evenly divided into two groups of 20 teeth each. Group 1 received root canal obturation with calcium silicate-based sealer (BioRoot ™ RCS), while Group 2 received resin-based sealer (AH Plus®). The study was conducted at District 1 Hospital, Ho Chi Minh City. Pain levels were assessed after obturation using the Visual Analog Scale (VAS). Results: The average age of participants was 53.6 years, with females accounting for 35% of the sample. A total of 37.5% of patients presented with periapical abscesses. After three months, 100% of the treated teeth showed resolution of abscesses and no remaining clinical signs. The highest average levels of spontaneous pain and pain on biting were recorded immediately after root canal obturation (Group 1: 2.9 and 3.0 points; Group 2: 2.9 and 3.6 points, respectively). Pain levels decreased progressively at 6, 12, and 24 hours, reaching their lowest at 72 hours (Group 1: 0 points; Group 2: 0.3 points) (p < 0.05). Conclusion: Calcium silicate-based sealer (BioRoot™ RCS) demonstrated clinical effectiveness comparable to epoxy resin-based sealer (AH Plus®) in the treatment of chronic periapical lesions.
