[Periodontal status in patients with oral submucous fibrosis].

OBJECTIVE

To investigate the periodontal status in patients with oral submucous fibrosis (OSF), and to provide reference for the treatment and prophylaxis in patients with OSF and betel chewers.

METHODS

Fifty samples clinically and pathologically diagnosed as OSF patients were selected as the OSF group, another 50 age-matched healthy volunteers in the similar living condition were compared with the OSF patients and non-betel nut chewers were classified as the control group. The 5 periodontal clinical parameters were collected and recorded, including plaque index, periodontal probing depth, clinical attachment loss, gingival index, and tooth count of bleeding of probing.

RESULTS

There was a significant difference in plaque index (PLI) between the OSF group (2.14+/-0.64) and the control group (1.7+/-0.89) (P<0.01). Periodontal probing depth (PD) was (1.98+/-0.70) mm in the control group, and (5.57+/-2.39) mm in the OSF group, with significant difference in PD (P<0.01). There was no significant difference in clinical attachment loss, gingival index, and tooth count of bleeding on probing between the 2 groups (P>0.05).

CONCLUSION

OSF patients tend to accumulate plaque, and have deep periodontal pocket, periodontal inflammation or severe periodontal damage.
