Abstract

BACKGROUND: In order to prove the idea that topical application of drugs can improve the clinical parameters affecting periodontal disease, a sound comparison should be made between topical therapeutic models. The aim of the present study was to assess the clinical efficacy of photodynamic therapy (PDT) and Salvadora persica (SP) gel as adjuncts to scaling and root planning (SRP) in the treatment of chronic periodontitis.

METHODS: The selected patients were divided into three groups, Group I (PDT + SRP), Group II (SP + SRP) and group III (SRP alone). Clinical inflammatory periodontal parameters including plaque index (PI), bleeding on probing (BOP), probing depth (PD) and clinical attachment level (CAL) gain were assessed. Assessment of crevicular fluid interleukin (IL)-6 and tumor necrosis factor alpha (TNF-α) was performed using enzyme-linked immunosorbent assay technique. All measurements were recorded at baseline, 3 months and 6 months follow-up periods, respectively.

RESULTS: A total of 73 patients completed the study. A significant improvement in the BOP was seen in Group II at both follow up visits when compared with other groups (p < 0.05). Only in Group-I that showed statistically significant reduction in moderate periodontal pockets at 3 months (p = 0.021), and significant reductions in deep pockets at 3-months (p = 0.003) and 6-months (p = 0.002), respectively. CAL gain also was reported to be seen in group-I at both visits (p < 0.05). Group- I and II significantly reduced the levels of IL-6 at 3-month period compared to Group-III. This reduction was further maintained by group-II and group-III at 6 months, respectively. TNF-α showed statistically significant decrease in Group II as compared to Group I and Group-III and this reduction was maintained by the end of 6-month visit (p = 0.045).

CONCLUSION: Both the treatment modalities PDT and SP helped in reducing periodontal inflammation. PDT reported significant gain in clinical attachment level, whereas the SP significantly reduced the bleeding levels.
