The effect of chlorhexidine gluconate chips on clinical status of peri-implant mucosa and plaque formation on healing abutments following single-stage implant surgeries.

Background: An experimental study was designed to evaluate the effect of chlorhexidine gluconate chips on clinical status of peri-implant mucosa and plaque formation on healing abutments following single-stage implant surgeries. Materials and Methods: Twenty-eight single-stage implant sites were grouped into 14 test and control sites. The study commences from the time of suture removal following surgery, designated as day 0. Chlorhexidine chip insertion into peri-implant sulcus in test sites was done on day 0, 10, and 20. Peri-implant crevicular fluid was collected on day 0, 10, 20, and 30 for biochemical estimation of aspartate aminotransferase (AST). The modified sulcus bleeding index (mBI) score was obtained in both test and control sites on day 10, 20, and 30. On day 30, all the healing abutments were unscrewed and sent for stereomicroscopic analysis to assess the plaque formation on its surface. Results: Statistically significant difference was not observed in AST levels and mBI in both test and control groups in various time intervals. In the stereomicroscopic assessment of healing abutment, mild grade of plaque accumulation was seen in three samples in test group, one sample in control group, and severe grade was seen in six samples in test group and nine samples in the control group. Conclusion: Inflammatory condition of peri-implant mucosa and plaque retentive properties on healing abutment surface were found to have reduced with the usage of chlorhexidine gluconate chips. However, the study failed to establish a statistically significant correlation of these observations.

A combined periodontal - prosthetic treatment approach to manage unusual gingival visibility in resting lip position and inversely inclined upper anterior teeth: a case report with discussion.

Excessive gingival visibility during smile is a common esthetic complaint in dentistry, but excessive gingival visibility in resting lip position is relatively uncommon condition. Several exclusive radical to conservative surgical treatment or its combination with orthodontic therapy to treat this condition are within the reach of every patient nowadays. A case report of an excessive gingival visibility because of altered passive eruption along with inversely inclined maxillary anterior teeth is presented here. A relatively simple treatment approach combining periodontal and restorative therapy is used here to achieve the desirable aesthetic results. The gingival exposure resulting from altered passive eruption was completely managed by a gingivectomy, but the inclined appearance of teeth was still an aesthetic complaint. After complete healing of gingivectomy surgery, appropriately designed crowns were given to rectify the inversely inclined appearance. A complete rehabilitation of patient's smile could be achieved, the case was followed up for 3 years and the condition was found satisfactory.

Inflammatory myofibroblastic tumor of maxilla showing sarcomatous change in an edentulous site with a history of tooth extraction following periodontitis: A case report with discussion.

Inflammatory myofibroblastic tumor (IMT) is a rare tumor of uncertain origin with variable biological behavior ranging from reactive lesions to highly aggressive malignancy. Oral IMTs are extremely rare and only 25 cases had been reported so far. A case of IMT with sarcomatous transformation in an extraction site with a history of tooth extraction following tooth mobility of an upper left molar tooth is presented here. The tooth was extracted following a complaint of gingival swelling and mobility of tooth. Though malignant transformation in IMTs had been documented in the extra oral sites, wide search of associated literature suggests, this is the first case of oral IMT showing malignant change associated with gingiva. The case report attempts to highlight the variant possibilities of tooth mobility other than periodontitis and the importance of assessing the primary cause of such conditions.

Clinical attachment level gain and bone regeneration around a glass ionomer restoration on root surface wall of periodontal pocket.

A case describing perio-restorative management of an accidental trauma in the mid portion of root on an upper left canine tooth following an ostectomy surgery is presented here. The traumatized root area was undergoing fast resorption and a chronic periodontal abscess had developed in relation to the lesion. The article illustrates the clinical and radiographic photo series of a periodontal flap surgery done to gain access into a subgingival region for the placement of Glass ionomer restoration on the root and its periodic follow up. The clinical condition of the area suggests 8 mm clinical attachment gain over the restoration and the review radiographs at definite intervals up to 18 months revealed evidence of consistent bone regeneration around the restoration. The article also highlights the various other possibilities, where this restorative material can be effectively used in conjunction with periodontal surgical procedures.
