CHITOSAN BASED PERIODONTAL POCKET INSERTS - FORMULATION, IN VITRO AND PRELIMINARY CLINICAL EVALUATION
Department of Pharmaceutics, Institute of Technology Banaras Hindu University, INDIA
The present paper concerns tlle in vitro and clinical evaluation of chitosan based periodontal inserts of ciprofloxacin hydrochloride (CPH). The effects of polymer concentration plasticizer drug loading and type and concentration of cross-linking agents (formaldehyde and glutaraldehyde) on CPH release were studied. The release of CPH followed a Q vs t1/2 profile. An increase in the plasticizer concentration (propylene glycol and glycerol) and drug loading resulted in a higher rate of CPH release; but the type of plasticizer did not show any significant effect on drug release,where as retardation was observed with fin increase in polmer concentration and cross-linking. Clinical evaluations of the inserts were carried out in patients suffering from periodontitis witll an average pocket depth of > 5 mm. Significant improvements were observed in various clinical indices as: Peridontal Index (PI), Bleeding Index (Bl), Periodontal Disease Index (PDI), Shick- Ash Modification of Plaque Criteria (SAPC) and Gingival Index (GI) and microbial paratmeters (%of G (+)and G (-) bacteria and Total Bacterial Count, (TBC) at the device inserted site thus affirming the therapeutic value of the inserts in the treatment of periodontal pocket formation.
