Twenty-three sites, belonging to 13 consecutive patients (7 females, 6 males, age =50±11) were studied. All patients were affected by chronic periodontitis presenting at least one vertical infrabony defect affecting a single–rooted tooth. Infrabony defects associated with perio-endo pathology were excluded. All sites were treated with endoscopic-assisted (Dental View-DV2, CA, USA) S+RP and than simply maintained.

The following measurements were registered: the distance between interproximal cement-enamel junction (CEJ) and base of the defect (BD), the distance between bone crest (BC) and BD and the angle of the defect defined by the previous two lines. Results Significant mean reduction of CEJ-BD and BC-BD distances were registered: 1.13±0.22mm (95% CI:0.68-1.59) and 0.82±0.19mm (95% CI:0.42-1.22) respectively (Student T for paired data: p=0.0001). The defect angle showed a significant mean increase of 6.29±2.71° (95% CI:0.67-11.92) (Student T for paired data: p=0.03). Bone remodelling occurred after non-surgical endoscopic-assisted periodontal therapy, led to a partial fill of the defect and opening of the defect angle. Conclusions The present work confirms the radiographic improvement of vertical bone defects also after endoscopic periodontal therapy. Randomized controlled studies are strongly demanded.

Abstract

Introduction The primary goal of non-surgical therapy (S+RP) is to remove subgingival deposits. The recent introduction of the endoscopy to this procedure has opened new effectiveness opportunities. Aim The aim of this work is to analyse the radiographic response of infrabony defects to endoscopic-assisted S+RP. Materials and methods Hypothesizing a difference between the means of the distances not inferior to 0.8 mm, with a power of 80% at an α level of 0.05, a minimum number of 12 patients was needed. Twenty-three sites, belonging to 13 consecutive patients (7 females, 6 males, age =50±11) were studied. All patients were affected by chronic periodontitis presenting at least one vertical infrabony defect affecting a single–rooted tooth. Infrabony defects associated with perio-endo pathology were excluded. All sites were treated with endoscopic-assisted (Dental View-DV2, CA, USA) S+RP and than simply maintained. Standardized x-rays were taken before and one year after the treatment. Each subject subscribed a specific informed consent. Radiographs were scanned and evaluated using an image analyser (Scion Image Analyzer, Scion, Frederick, MD, USA). The following measurements were registered: the distance between interproximal cement-enamel junction (CEJ) and base of the defect (BD), the distance between bone crest (BC) and BD and the angle of the defect defined by the previous two lines. Results Significant mean reduction of CEJ-BD and BC-BD distances were registered: 1.13±0.22mm (95% CI:0.68-1.59) and 0.82±0.19mm (95% CI:0.42-1.22) respectively (Student T for paired data: p=0.0001).
