Abstract

Use of saliva for periodontal screening has been the subject of considerable research activity. Aspartate aminotransferase (AST) is a cytoplasmic enzyme present in saliva and has been studied as marker of periodontal disease. The purpose of this study was to determine AST levels in saliva in patients with periodontal disease before and after therapy.

Sixty subjects (30 control or healthy and 30 patients of inflammatory periodontal disease; mean age 37 years) were enrolled in this study. Measurements of clinical parameters, which includes recording community periodontal index of treatment needs (CPITN) scores, and collection of non stimulated whole saliva were performed at base line and 3 weeks after scaling and root planing. Saliva was biochemically analyzed for AST levels. Statistical analysis was performed by using paired t test and One way ANOVA.

Median value and interquartile range of AST in saliva in CPITN group C0, C1, C3 and C4 was found to be 31.25 U/l (28.98–37.35 U/l), 32.6 U/l (27.42–39.15 U/l), 38.0 U/l (34.42–40.75 U/l) and 96.5 U/l (88.57–107-30 U/l) respectively. No statistically significant difference was found between C0, C1 and C3 except for C4. (p < 0.05). Statistically significant difference was found between healthy and inflammatory periodontal patients (90.6 ± 19.69 U/l) regarding their AST levels in saliva (p < 0.001) but no significant difference was observed between healthy and treated patients (35.36 ± 9.79 U/l).

Our results suggest that AST levels in saliva increases in severe periodontal disease condition and decreases after treatment and is comparable to healthy subjects.
