Influence of nervous tendencies on oral health status and lifestyle habits.

Abstract

It is presumed that people with nervous tendencies brush their teeth for long durations, and, we aimed to investigate how nervous tendencies affect oral health status and lifestyle habits. Three hundred and sixty patients who visited the Senri Dental Clinic, affiliated with the Sunstar Foundation, and were being treated for periodontal diseases between 11 January 2017 and 10 April 2017 were enrolled. A total of 323 respondents (101 men and 222 women) were considered eligible. Nervous tendencies were investigated using the Fujinami neurotic index (FNI) and its derivative, the neurotic index (NI). Patients with NIs of ≥20 were included in the 'needs caution' group, whereas those with NIs of <19 comprised the 'healthy' group. The plaque score; periodontal pocket depth; bleeding on probing degree; gingival recession; crevice defects; oral conditions, such as cervical fillings and lifestyle habits were compared between the groups. No statistically significant differences in oral status were observed between the groups. On the other hand, the needs caution group had significantly longer brushing durations and lower usage of auxiliary teeth cleaning tools than the healthy group. Sleep duration was significantly shorter in the needs caution group than in the healthy group. Patients with strong nervous tendencies had long oral brushing durations and low usage of auxiliary cleaning tools. However, these factors did not negatively affect oral health status. These results could aid in understanding patients with strong nervous tendencies and in developing appropriate dental health guidance measures.
