Besides, the early healing of the gingival and periodontal wounds in oral cavity should be emphasized to promote the treatment outcome. Several studies pointed out a potential positive effect of silver nanoparticles (NPs) on the healing process of skin wounds. The present work aimed to design silver NPs periodontal dressing and then, evaluated its effects on gingival wound healing following operation. Methods: Thirty healthy adolescent female rabbits were used in this study. They had intact teeth and the clinical and radiographic examination revealed no periodontal disease. Silver NPs were added to carbonate methyl cellulose as base with two different concentrations of 25% v/v (Group A) and 50% v/v (Group B). On the basis of simple randomized allocation, gingivectomy was performed at the buccal gingiva of the left and right mandibular incisors and subsequently, untreated wounds in the control area were covered with periodontal pack and periodontal dressings A and B were applied in the test regions. Histological changes were monitored in day 4 and 7 post operation to evaluate the inflammatory and repair stage of healing process. Results: We observed significant difference in the inflammatory and repair parameters of the healing process between surgical sites treated with this periodontal dressing and control group. Besides, wounds treated with silver NPs dressing in general terms had all the hallmarks of relatively complete healing one week post operatively. Conclusion: The results indicated positive potential therapeutic effects for this new formulation of periodontal dressing on acceleration of surgical wound healing that led to improvement of periodontal treatment consequences following operation.展开更多

This is of a reactive rather than neoplastic nature and its pathogenesis is uncertain. PCOF predominantly affects adolescent and young adults with greatest prevalence around 28 years. We report here a rare clinical case of PCOF of the mandible, 1 cm mesiodistally and 1.5 cm occluso-gingivally in diameter, which caused difficulty in eating and speech, in a 42-year-old female patient. She was asymptomatic for 1 year and on follow-up for 6 mo post surgically showed gingival health and normal radioopacity of bone without any recurrence. Clinical, radiographic and histological characteristics are discussed and recommendations regarding differential diagnosis, treatment and follow up are provided. The controversial varied nomenclature and possible etiopathogenesis of PCOF are emphasized.展开更多

Anamnesis revealed that she experienced laser gingivectomy to have remarkable teeth. Clinical examination showed that maxillar alveolar bone was partially uncovered with gingivae and periosteum. Interproximal necrosed area was observed. She had sensitivity at her maxillar anterior teeth. Furthermore, she was so anxious and depressed. In order to ensure more blood supply and clot formation, perforations on uncovered cortical bone was prepared. Avoiding from infection antibiotic, antiseptic gel and for epithelization vitamin E gel were prescribed. During one month she was recalled every third day. Recall times diminished periodically, as new tissue evolves. Although laser's irreversible photothermal effects on soft and hard tissue, after a year all denuded areas were covered with healthy tissues without any surgical procedures. Histopathologic comparing showed severe lymphocyte infiltration and increased fibrosis and kollagenization in restored gingiva, additionally epithelial loss was observed. Since there is not a case report about the complications of laser gingivectomy in litera-ture, we tried to represent a treatment plan that may be elucidative for clinicians.展开更多
