Chitosan Nano-hydroxyapatite Hydrogel in Non-Surgical Treatment of Intrabony Defect

October 6 University24 enrolled

Overview

The aim of this study was to evaluate the clinical effect of Chitosan with nano-hydroxyapatite hydrogel in the treatment of periodontal intrabony defects.

Periodontitis is a chronic inflammation of the periodontium that extends beyond the gingiva and involves the destruction of the connective tissue attachment of the teeth. Treatment modalities of periodontitis includes local drug delivery such as chitosan which is a derivative of the exoskeleton of many arthropods including prawns, lobsters and crabs. Chitosan has been used in guided bone regeneration, hemostasis of surgical wounds, and coating of dental implants, in reconstruction of temporomandibular joint disc and guided periodontal tissue regeneration. Moreover, chitosan has been used for preventing demineralization. HA also called hydroxylapatite, is a naturally occurring mineral form of calcium apatite with the formula Ca5(PO4)3(OH). The OH- ion can be replaced by fluoride, and carbonate, producing fluorapatite or chlorapatite. It crystallizes in the hexagonal crystal system.

Interventions

Nano-HAP/Chitosan hydrogelOTHER

The periodontal pockets more than or equal 3-5mm were isolated. Chitosan and nano-HAP hydrogel were prepared in the same steps that were mentioned in the methodology and then the prepared gel was applied to the test site of patients with the deepest probing pocket measurement once per week for 3 weeks. Periodontal dressing (Coe-pack) was to secure the hydrogel in place.

Outcomes

Primary Outcomes

Gingival index

Gingival index (GI) used for the assessment of prevalence and severity of gingivitis. A score from 0 to 3 is given to each area of the tooth.0.1-1.0 = mild inflammation; 1.1-2.0 = moderate inflammation from, and 2.1-3.0 signifies severe inflammation. It was evaluated for every patient included in the study, 3 and at 6 months after treatment.
