Effect of gingival biotype on total crown repair and gingival crevicular fluid inflammatory factors

Shanghai Kou Qiang Yi Xue. 2023 Dec;32(6):668-672.ABSTRACTPURPOSE: To explore the effect of thick and thin sputum on the restoration of oral anterior teeth and the index of gingival crevicular fluid.METHODS: A study was conducted on 80 patients (130 teeth) who underwent full-ceramic crown treatment for anterior tooth restoration in Jiangnan University Affiliated Hospital 's oral clinic. The patients were divided into thick gingival type (42 cases, 67 teeth) and thin gingival type (38 cases, 63 teeth) according to their gingival biotype. The two groups were compared before and after the restoration with improved plaque index (mPI), modified bleeding index (mBI), probing depth (PD), clinical evaluation score of oral prosthesis, tumor necrosis factor-alpha (TNF-alpha) and IL-1 β(interleukin-1β) in gingival crevicular fluid. Statistical analysis was performed with SPSS 21.0 software package.RESULTS: Before treament, there were no significant differences in mPI, mBI and PD between the two groups (P＞0.05); 12 months after treament, mPI, mBI and PD of the thin gingiva group were significantly lower than those of the thick gingiva group(P＜0.05). Before treament, there were no significant differences in TNF-α and IL-1β levels in gingival crevicular fluid between the two groups(P＞0.05); 12 months after treament, TNF-α and IL-1β levels of the thin gingiva group were significantly lower than those of the thick gingiva group(P＜0.05). Six months after treament, there were no ...
