Effectiveness of Controlled Release Chlorhexidine Chip as an Adjunctive to Scaling and Root Planning for the...

Chlorhexidine is considered one of the options for the management of periodontal diseases. This present study was conducted to assess the usefulness of controlled-release chlorhexidine chip in addition to scaling and root planning (SRP) while comparing with SRP alone in the treatment of chronic periodontitis clinically, microbiologically and radiographically.

This study included 20 patients age ranged from 30 to 55 years with chronic periodontitis. A total of 40 sites were selected. Two bilateral pockets with probing depth 4-6 mm were put in test and control groups in all subjects. SRP plus Periochip™ was used in the test group and SRP alone in the control group. In all subjects, all the analysis such as clinical parameters, the radiographic and anaerobic culture of P. gingivalis, T. denticola, and T. forsythia were performed and compared in both groups at baseline and 3 months interval.

There was a significant improvement in all clinical and radiographic parameters in the test group in comparison to control group. Total colony counts also reduced significantly. At baseline, Tf was recovered from 15 test group sites and 16 control group sites, Pg from 14 test group and 14 control group sites, Td from 16 test group and 15 control group sites. At 3 months, Tf was recovered from 4 test group and 10 control group sites, Pg from 3 test group and 9 control group sites, Td from 4 test group and 8 control group site.

Periochip™ placement as an adjunct to SRP, showed promising results when compared to SRP alone.

Periochip is considered the best treatment option in the treatment of chronic periodontitis.
