Methods Data from 1000 untreated adults (age > 18) collected in Beijing from January 2000 to January 2001 were utilized in the analysis. Half of the subjects were examined by Gingival Bleeding Index (GBI) and the other half by Sulcus Bleeding Index (SBI). The data were sorted out and calculated according to CPI teeth and random half-mouth teeth methods. The results of the 2 methods were separately compared with those of full-mouth examination. Results There was a significant difference between CPI teeth method and full-mouth examination (P<0.05) in both GBI and SBI. In contrast, compared with full-mouth examination, significant difference was not observed in diagonal or ipsilateral half-mouth results in SBI (P>0.05), nor in diagonal half-mouth results in GBI (P>0.05) Conclusions The results of CPI teeth method on gingival bleeding could not reflect the full-mouth situation. Ipsilateral and diagonal half-mouth results can serve as a substitute for full-mouth results in SBI, while diagonal half-mouth results in GBI.展开更多

Methods: A total of 156 patients with gingival pain and swelling after root canal therapy due to dental pulp necrosis were included in the study and randomized into the control group (n=78) and teh treatment group (n=78). The patients in the control group were given metronidazole tablets. On the above basis, the patients in the treatment group were given local injection of neurogrowth factors. 10-day treatment was regarded as one course, and the patients were continuously treated for 2 courses. The improvement of clinical symptoms before and after treatment in the two groups was evaluated. Gingival sulcus index and serum inflammatory cytokines before and after treatment in the two groups were detected and compared. Results: When compared with before treatment, the periodontal soft tissue swelling, tooth mobility, and periapical pain scores after treatment in the two groups were significantly reduced, and those in the treatment group were significantly lower than those in the control group. When compared with before treatment, the gingival sulcus bleeding index 1 and 2 courses after treatment in the two groups was significantly reduced, and that 2 courses after treatment was significantly lower than that after 1 course treatment. The gingival sulcus bleeding index 1 and 2 courses after treatment in the treatment group was significantly lower than that in the control group. When compared with before treatment, the serum IL-8 and IL-6 levels after treatment in the two groups, and TNF-α level after treatment in the treatment group were significantly reduced, and the above indicators in the treatment group were significantly lower than those in the control group. Conclusions: The neurogrowth factors in the treatment of gingival pain and swelling in patients with dental pulp necrosis after root展开更多
