Effect of Nonsurgical Treatment on Salivary HGF Levels in Population with Periodontal Disease: A Quasi-experimental Study

AIM: To assess the effect of nonsurgical treatment on salivary hepatocyte growth factor (sHGF) levels in a population with periodontal disease: a quasi-experimental study. METHODS: Eighty-one patients (aged 30–70 years) were divided into three groups based on the gingival index, probing depth, clinical attachment loss, and radiographic evidence of bone loss: healthy (group I), gingivitis (group II), and chronic periodontitis (group III). Saliva samples were collected from these groups at baseline. At 8 weeks, saliva samples were collected again from group II and group III after the patients went through nonsurgical periodontal treatment. The levels of HGF were estimated using enzyme-linked immunosorbent assay (ELISA). The clinical parameters and HGF levels among all groups were analyzed using a one-way analysis of variance (ANOVA) using SPSS 17 version. RESULTS: At baseline, the highest mean HGF concentration in saliva was observed for group III (3455.83 ± 1463.44 pg/mL), and the least in group I (469.43 ± 317.13 pg/mL). Following nonsurgical periodontal treatment, the mean HGF concentration decreased significantly in group III and group II (p < 0.05). A significant positive correlation between clinical parameters and HGF levels was also seen (p < 0.05). CONCLUSION: HGF concentration showed a positive correlation with the progression of periodontal disease. CLINICAL SIGNIFICANCE: Following nonsurgical periodontal therapy, the levels of HGF decreased significantly, suggesting that HGF could be useful for monitoring the response to periodontal therapy.
