Periodontal plastic surgery often involves palatal donor site, thereby creating an open wound that is prone to postoperative complications such as bleeding, pain, and slow healing process. To prevent the same, platelet-rich fibrin (PRF) and gelatin sponge (GS) were utilized equally at the donor site in six patients. Patients were monitored at the 1, 2, 3, and 4 weeks after surgery for postoperative discomfort (D), consumption of analgesics during first postoperative week, alteration of sensitivity (AS), change in feeding habits (CFH), complete wound epithelialization (CWE), and healing index (Landry 1998). Two patients in the GS group showed significantly early CWE, higher healing index score, and less D, AS, and CFH postoperatively in comparison to the PRF group. It was suggested that GS can also be considered as an effective, economical, and biocompatible dressing material of choice to enhance wound healing and to minimize postoperative complications associated with the donor site.

Pyogenic granuloma is a non-neoplastic, exuberant, reactive lesion seen in response to local irritation or trauma caused by dental calculus, bacterial plaque, caries and restorations, with a strong predilection for the gingiva. It is among the frequently encountered oral lesions, occurring at a challenging oral site, the gingiva. Herein, we report a 71-year-old medically compromised Caucasian female who presented with a relatively large lobulated pyogenic granuloma on the buccal gingiva of the maxillary molar-premolar region. Total surgical excision was performed with an 840nm diode laser followed by the placement of hyaluronate gel and relevant periodontal dressing. Two weeks after surgical excision, complete healing was observed, but patient denied replacement of dental restoration. After 4 months of follow-up, an overall reduction of associated teeth mobility was also observed, with a minor recurrence in gingival inflammation. The objective of this report is to briefly review clinical, radiographic and histological findings of pyogenic granuloma along with a detailed discussion on its management through a diode laser.

This study evaluated the effect of antimicrobial photodynamic therapy (aPDT) on the endodontic treatment of apical periodontitis (AP). AP was induced in 48 premolars of 6 dogs. After biomechanical preparation, the teeth were divided into 4 groups: Calcium-Hydroxide (CH)/120d and CH/180d: root canals filled with CH-based dressing for 15 days before obturation; aPDT/120d and aPDT/180d: conditioning with phenothiazine photosensitizer (10 mg/mL) for 1 minute and irradiation with diode laser in the same session as obturation. Root filling was performed with AH Plus sealer. After the experimental periods, animals were euthanized and teeth were submitted for histology. HE staining was performed for descriptive analysis of the periapical region, measurement of apical periodontitis and for inflammatory cells, and blood vessels count. Immunohistochemistry was performed for osteopontin (OPN) and alkaline phosphatase (ALP). Data were analyzed statistically by two-way ANOVA and chi-square test (α = 5%). Teeth in Group CH/120d presented only a slightly enlarged periodontal ligament (PL) with advanced repair. Group aPDT/120d presented the PL moderately enlarged, with moderate inflammatory infiltrate and few collagen fibers. The same pattern was observed at 180 days. AP lesions in CH-treated groups were smaller than those in aPDT-treated groups (p < 0.001) with more blood vessels (p < 0.0001), regardless of the evaluation period, without significant differences in the number of inflammatory cells (p > 0.05). CH-treated groups showed significantly more intense immunostaining for ALP and OPN (p < 0.001) in both periods. Although aPDT stimulated angiogenesis and expression of bone formation markers, the two-session endodontic treatment with CH-based dressing promoted better apical periodontitis repair.
