ABSTRACT
Aims and Objective: The present study aimed to evaluate 2 bone graft materials, that is, biphasic hydroxyapatite and ??tricalcium phosphate, in the treatment of periodontal vertical bony defects. In term of attachment level, probing depth and radiographic bone level changes. Also, a new digital method of radiographic assessment was used for measurement of vertical bone defect. Material and Methods: Ten subjects with periodontitis and having two or more vertical bony defects were enrolled in the study. Patients were classified randomly into 2 groups. Group I consisted of the experimental site where defect was filled with biphasic hydroxyapatite and ??tricalcium phosphate graft and Group II consisted of control site where only the open flap debridement (OFD) was carried out. Clinical parameters were evaluated at baseline, 3 and 6 months; Radiographs were taken at baseline and 6 months after surgery. Results: Overall, by the end of 6 months, biphasic hydroxyapatite and ??tricalcium phosphate and OFD treatment groups exhibited a significant reduction in probing depth almost by 75% and gain in clinical attachment level at follow?up. In the biphasic hydroxyapatite and ??tricalcium phosphate group, radiographic bone level gain appeared to be greater than in the OFD group. Conclusion: In the present study, biphasic hydroxyapatite and ??tricalcium phosphate have shown promising results and have showed reduction in probing depth, a resolution of osseous defects and gain in clinical attachment level when compared to open flap debridement.
ABSTRACT
The primary goal of periodontal therapy is to restore the tooth supporting tissues lost due to periodontal disease. The aim of the present study was to evaluate the efficacy of xenogenic bone graft with open flap debridement (OFD) in treatment of periodontal intrabony defects. Methods: Twenty intrabony defects were surgically treated. The defects were randomly assigned to treatment with OFD + bone graft (Group B) or OFD alone (Group A). The clinical efficacy of two treatment modalities was evaluated at 9months postoperatively clinically and radiographically. Results: Statistically significant intra group improvements were seen with all the hard tissue and soft tissue parameters in both test and control groups. Statistically significant improvements were seen in group B with clinical parameters and the mean defect fill (AC-BOD) when intergroup comparisons were made. Conclusion: Treatment with bone graft + OFD led to a significantly more favorable clinical outcome in intrabony defects as compared to OFD alone.
ABSTRACT
Objectives: The purpose of this clinical study is to determine the efficacy of Fisiograft as a bone graft materialin the treatment of three wall vertical defects in generalized chronic periodontitis patients and theirclinical and radiological evaluation. Materials and methods: Twenty patients (with 30 defects) diagnosedwith generalized chronic periodontitis having two or more three wall vertical defects were selected for thisstudy. Clinical parameters like plaque index, gingival index, probing pocket depth and clinical attachmentlevels were recorded at different points of time over six months. Radiographic evaluation included the depthof the bone defect and the percentage of bone defect fill, and was carried out for both the groups at baseline,three months and six months. After recording clinical parameters and administering phase-1 therapy, thesites were randomly treated either with Fisiograft or open flap debridement only. Results: At the end of sixmonths there was a significant reduction in the plaque and gingival scores in both test and control groups.There was 64% decrease in probing pocket depth for the test site as compared to 55% decrease seen for thecontrol group. Similarly there was an 85% gain in clinical attachment level from the baseline to six monthspost operatively for the experimental group in comparison to 69% gain for the control group. Furthermore,44% bone fill was observed for the experimental site whereas only 18% of bone fill was evident in the controlsite. Conclusion: Fisiograft improves healing outcomes, leads to a reduction of probing depth, a resolutionof osseous defects and a gain in clinical attachment, compared with open flap debridement by itself.
Objetivo: O objetivo do presente estudo clínico foi determinar a eficácia do Fisiograft®, como material de enxerto ósseo, no tratamento de defeitos ósseos verticais de três paredes em pacientes com periodontite crônica,bem como avaliações clínica e radiográfica. Materiais e métodos: Vinte pacientes (com 30 defeitos)diagnosticados com periodontite crônica generalizada, portando dois ou mais defeitos ósseos verticais detrês paredes foram selecionados para o estudo. Parâmetros clínicos como índice de placa, índice gengival,profundidade de bolsa à sondagem e níveis clínicos de inserção foram registrados em diferentes intervalos de tempo até seis meses. Avaliações radiográficas incluíram a profundidade do defeito ósseo e a porcentagem de preenchimento do defeito ósseo, sendo realizadas em ambos os grupos imediatamente (baseline),em três meses e seis meses. Após registrar os parâmetros clínicos e administrar a terapia de fase-1, os locais foram tratados aleatoriamente com Fisiograft® ou retalho de espessura total somente. Resultados: Ao fim do período de seis meses houve redução significativa nos índices de placa e gengival em ambos os grupos,controle e experimental. Houve redução de 64% na profundidade de bolsa à sondagem para os locais de teste comparado, 55% de redução no grupo controle. Similarmente, houve ganho de 85% no nível clínico de inserção do baseline para o período de seis meses de pós-operatório para o grupo experimental em comparação ao ganho de 69% para o grupo controle. Adicionalmente, um preenchimento ósseo de 44% foi observado para os locais experimentais, enquanto somente 18% de preenchimento foi evidente nos locais de controle.Conclusão: O Fisiograft® melhora os resultados de cicatrização, promove redução na profundidade de sondagem,constitui uma resolução para os defeitos ósseos e aumento na inserção clínica, comparado ao retalho de espessura total somente.

To evaluate the efficacy of the polylactide-polyglycolide copolymer Fisiograft® as a bone graft material in the treatment of interproximal intrabony defects clinically and radiographically. Methods: A total of 22 intrabony defects in 8 patients with chronic periodontitis (4 males and 4 females) aged 20 to 55 years were recruited and divided equally into two groups: control (open flap debridementalone) and experimental (open flap debridement with Fisiograft®). Recordings of probing pocket depth (PPD), clinical attachment level (CAL), gingival margin position (GMP) and radiovisiographic assessment was done at baseline and 6 months. Results: Statistical analysis was done by Wilcoxon Signed Rank test for intra-group comparisons and Mann-Whitney U-test for inter-group comparisons. The clinical parameters PPD, CAL and GMP were found to be statistically significant(p<0.05) within each group. Inter-group comparison showed only the CAL gain to be statistically significant (p<0.01). In relation to hard tissue changes, statistically significant (p=0.05) result was seen for the percent filling of the original defect, comparing the experimental and control groups 6 months postoperatively. Conclusions: Placement of Fisiograft® resulted in better healing of intrabony defects as assessed clinically and radiographically when compared to open flap debridement alone.
