The fluctuation of periodontal indexes during the same day: a pilot study.

Aim: This was to determine if periodontal indexes, from which we choose the periodontal therapy, can be influenced by the time of day they are collected. Material and Methods: Using specific inclusion and exclusion criteria, we enrolled 21 patients. The study involved the comparison of the full-mouth plaque score (FMPS), full-mouth bleeding score (FMBS) and periodontal screening and recording (PSR) index in three successive stages of the same day, (8.30-T1, 11.30-T2, 14.00-T3) during the maintenance phase. Oral status of the patients and lifestyle were also considered. Results: Comparing T1, T2 and T3 it can be seen that the FMBS was significantly different in each phase: T1 (m ± SD 9,17 ± 6,61), T2 (6,95 ± 6,50) and T3 (5,77 ± 5,95). T1-PSR (0,91 ± 0,21) was greater than T2 (0,81 ± 0,26) and T3 (0,80 ± 0,25). The evaluation differential resulted positively conditioned by the number of teeth with a negative prognosis (NPT) for PSR and for females for FMPS. The NPT affected the PSR negatively and the FMPS and FMBS positively. Years of smoking and the number of cigarettes per day affected the FMPS and FMBS negatively whilst being a smoker clinically improved the FMPS and FMBS. Conclusion: The FMBS and PSR show significant fluctuation during the day. In order to achieve more reliable data of the indices, multiple recordings during the day should be taken. The NPT and smoking are able to influence, in a complicated way, the periodontal indices and their fluctuations. Abstract N P0229 ISSN:1600-051X (Electronic)
