Healing of Periapical Bone Lesion After Periradicular Surgery And Graft Placement- Clinical And Radiographic Evaluation

Objectives: 1.To clinically evaluate the healing process following periapical surgery with Chitra granules 2.To radiographically evaluate healing, following periapical surgery with Chitra granules. 3.To compare the bone healing in the study group, clinically and radiographically following the modalities of treatment, with that of the control group (without graft). Materials: 1.Chitra hydroxyapatite granules. 2. Gutta-percha — for root canal obturation by lateral condensation. 3. High Copper amalgam used as retrofilling materials. To evaluate healing after periapical surgery using Chitra granules, 22 patients were selected from out patient section of Department of Conservative Dentistry and Endodontics, Govt. Dental College, Kozhikode,based on clinical and radiographical evaluation. The study group consisted of 13 males and 9 females. All were of the age group 15-35 years. After selection they were randomly divided into two groups A and B. In group A the Chitra granule were placed in the bony defect and in group B the defect were left as such after surgery. Results: Clinical parameters showed better early symptom free condition in group A compared to group B. But data found statistically insignificant (t-7.27,df-1.8, P >0.05). Radiographical evaluation data analysis showed statistically significant difference among group A and group B. Conclusion: Biocompatible Chitra granule not only obliterates the cavity but act as a scaffold for bone growth and prevent scar tissue formation.It is osteoconductive. In comparison to the conventional periapical surgery, the placement of Chitra granules facilitates bone regeneration more easily. The material is found to be very cost effective, easily available, easy to manipulate and involves least complication to both clinicians and patients.
