Research paper thumbnail of Improvement of Periodontal Parameters with the Sole Use of Free Gingival Grafts in Orthodontic Patients: Correlation with Periodontal Indices. A 15-Month Clinical Study

Methods: A total of 19 patients underwent periodontal examination before orthodontic treatment. Patients received oral hygiene instruction and professional hygiene therapy. Where needed; full periodontal treatment was completed. Only periodontally stable patients were included in the study. Periodontal indices and keratinized tissue were recorded at time 0 (T0) (delivery of orthodontic appliances), and at three months (T1) during orthodontic therapy; when surgery was performed. At T1; orthodontically treated sites with minimum keratinized tissue (≤1 mm) received a free gingival graft to enhance the band of keratinized tissue. At three months after surgery (T2), new measurements were recorded. The orthodontics-treated sites after three months (T1) were used as control. The same sites were used as a test thr...

The aim of this investigation was to evaluate the results obtained with the combination of autogenous bone grafting plus calcium sulfate and to compare this outcome with the results obtained using autogenous bone grafting with a bioabsorbable membrane. Methods: Twelve subjects participated in this split-mouth trial. Twelve 2-or 3-wall periodontal defects were treated with a combination of autogenous bone grafting plus calcium sulfate (test) and were compared to 12 defects treated with autogenous bone grafting with a bioabsorbable membrane (control). Before surgery, subjects were instructed in oral hygiene techniques, and scaling and root planing were completed. Surgery was identical for both groups except for the regenerative material. After healing, subjects followed a periodontal maintenance program. Probing depth (PD), clinical attachment level, and bleeding on probing were recorded at baseline, 6 months, and 6 years. Results: There were no statistical differences between test and control defects at baseline. At 6 months, there was a PD reduction of 4.3-1.0 mm in the control group and 4.4-1.1 mm in the test group. There was a clinical attachment gain of 3.5-1.1 mm in the control group and 3.6-1.0 mm in the test group. At 6 years, there was a PD reduction of 3.3-1.0 mm in the control group and 4.2-1.2 mm in the test group. There was a clinical attachment gain of 2.6-1.2 mm in the control group and 2.4-1.1 mm in the test group. Differences between treatment groups were not statistically significant at 6 months or 6 years. Conclusion: Both therapies led to significant short-and long-term improvements in the outcome variables assessed.

Its biocompatibility and resorbability give it significant advantages in the treatment of periodontal and endodontic defects. Clinically guided tissue regeneration procedures have demonstrated significant positive clinical change, beyond that achieved with debridement alone, in treating intraosseous defects. The aim of the present investigation was to evaluate the clinical results obtained with autologous bone plus calcium sulfate, and to compare them with the results obtained using autologous bone plus membrane. A total of 12 patients were treated in the present investigation. A split-mouth design was utilized. Twelve 3-wall periodontal defects were treated with calcium sulfate plus autologous bone graft (test) and compared with 12 contra-lateral defects treated with a bioabsorbable membrane plus autologous bone graft (control). Before the surgical procedure, patients were instructed about oral hygiene and scaling and root planing (SRP) was completed. Probing depth (PD), clinical attachment level (CAL), and bleeding on probing (BOP) were recorded at baseline and 6 months. There were no statistical differences between test and control defects at baseline. BOP was 58% and 50% for control and test defects, respectively. Mean PD was 7.75+/-0.96 mm (control) and 8.0+/-1.28 mm (test). Mean CAL was 8.58+/-1.31 mm (control) and 8.83+/-0.91 mm (test). At 6 months, mean PD was 3.41+/-0.51 (P = 0.0022) for control defects and 3.58+/-0.51 (P = 0.0022) for test defects. CAL showed a mean gain of 5+/-0.85 for controls (P = 0.0022) and 5.25+/-0.75 for test defects (P = 0.0022). Thus, there was a mean reduction of PD of 4.33 mm (56%) for control sites and 4.42 mm (55%) for test sites. The mean clinical attachment gain was 3.57 mm for control sites and 3.58 mm for test sites. As there were no sham-operated controls, it is not clear that the healing of these test or control-treated sites was any better than similar 3-walled defects sham operated. Both therapies led to short-term improvement of the measured parameters; neither was superior to the other.

The radiolucency was asymptomatic, round, presented distinct margins, and was not in contact with the roots of the adjacent teeth. These teeth were vital. Under local anesthesia the lesion was separated with some difficulty from the bone tissue and enucleated. Macroscopically the lesion had a hard consistency. The following may be considered in differential diagnosis: periapical granuloma, radicular cyst, periapical cemento-osseous dysplasia in the early lytic stage, traumatic bone cyst, odontogenic fibroma, unilocular ameloblastoma, unicystic ameloblastoma, adenomatoid odontogenic tumor, calcifying odontogenic cyst, ameloblastic fibroma, myxoma, and central giant cell granuloma. You are asked to consider the differential diagnosis for this case during the next month. In the next issue of the Journal the possibilities will be discussed and the most likely interpretation given.
