Options to avoid the second surgical site: a review of literature.

As esthetics gain importance, periodontal plastic surgical procedures involving soft tissue grafts are becoming commoner both around natural teeth as well as around implants. Periodontal soft tissue grafts are primarily used for the purpose of root coverage and in pre-prosthetic surgery to thicken a gingival site or to improve the crestal volume. Soft tissue grafts are usually harvested from the palate. Periodontal plastic surgical procedures involving soft tissue grafts harvested from the palate have two surgical sites; a recipient site and another donor site. Many patients are apprehensive about the soft tissue graft procedures, especially the creation of the second/donor surgical site in the palate. In the past decade, newer techniques and products have emerged which provide an option for the periodontist/patient to avoid the second surgical site. MucoMatrixX, Alloderm(®), Platelet rich fibrin, Puros(®) Dermis and Mucograft(®) are the various options available to the practicing periodontist to avoid the second surgical site. Use of these soft tissue allografts in an apprehensive patient would decrease patient morbidity and increase patient's acceptance towards periodontal plastic surgical procedures.

Intraoral manifestations in a patient with Epidermal nevus syndrome.

AIM: To report rare findings of oral and periodontal manifestations in a patient with Epidermal nevus syndrome (ENS). BACKGROUND: The ENS describes the rare association of an epidermal nevus with abnormalities of central nervous system,ocular and skeletal abnormalities. Reports of oral involvement have been few. Also, most of the intraoral lesions have been reported in patients with nevi that do not fulfill the criteria for the diagnosis of ENS. CASE DESCRIPTION: This report describes a case of ENS that, in addition to cutaneous manifestations showed skeletal involvement and intraoral manifestations such as the extension of the nevi on the face intraorally involving the labial mucosa, hypoplasia, hypodontia of teeth and severe periodontal destruction. CONCLUSION: Patients with extensive epidermal nevi and systemic abnormalities should be suspected of having the ENS. Evaluation and management of patients with ENS requires a multidisciplinary team approach involving the dermatologist, pediatrician, ophthalmologist, neurologist, genetist, plastic surgeon and orthopedic services. Although uncommonly described in association with ENS, significant intraoral lesions do occur. Periodontal manifestations as in our patient, which to our knowledge has not been described in association with ENS so far, may also be present. CLINICAL RELEVANCE: Alteration of the response of periodontal tissues to dental plaque in the presence of certain systemic diseases has been reported, but not in association with ENS. Severe periodontal destruction due to exaggerated response to dental plaque was seen in the present case. Hence, emphasis on oral hygiene maintenance in such patients is essential. Patients with ENS must be evaluated periodically as they show a persistent predisposition for the development of tumors.

Combined soft and hard tissue augmentation for a localized alveolar ridge defect.

Ideal alveolar ridge width and height allows placement of a natural appearing pontic, which provides maintenance of a plaque-free environment. The contour of a partially edentulous ridge should be thoroughly evaluated before a fixed partial denture is undertaken. Localized alveolar ridge defect refers to a volumetric deficit of the limited extent of bone and soft-tissue within the alveolar process. These ridge defects can be corrected by hard tissue and/or soft-tissue augmentation. A 30-year-old male patient was referred to the Department of Periodontology for correction of Seibert's Class III ridge defect in the lower anterior region. Granulation tissue/connective tissue present at the base of the defect was removed after elevation of full thickness flap. MucoMatrixX, an animal derived, collagen based soft-tissue graft was sutured to the labial flap and bone graft was placed into the defect. If a soft-tissue graft material could be used to replace the palatal grafts, then all the possible complications associated with donor site would be eliminated and above all periodontal plastic surgery and ridge augmentation would be better accepted by patients.

Presence of Helicobacter pylori in subgingival plaque of periodontitis patients with and without dyspepsia, detected by polymerase chain reaction and culture.

BACKGROUND: Helicobacter pylori is an important gastrointestinal pathogen that is strongly associated with gastritis as well as peptic ulcer disease. Antimicrobial therapy frequently fails to cure H. pylori infection, which suggests there may be sanctuary sites where the organism resides. This study was aimed to assess the role of oral cavity as a reservoir of H. pylori by evaluating the occurrence of the organism in subgingival plaque of dyspeptic patients by polymerase chain reaction as well as culture. MATERIALS AND METHODS: Thirty chronic periodontitis patients whose biopsy specimens were found to be H. pylori positive with rapid urease test and histopathologic examination were considered as cases and 20 chronic periodontitis patients who never had any symptoms of gastritis or peptic ulcer were taken as controls. Subgingival plaque samples were collected and sent to microbiological laboratory for detection of H. pylori by 16S rRNA based polymerase chain reaction as well as culture. RESULTS: 60% of the samples were found to be positive with polymerase chain reaction in the case group when compared to 15% in the controls. Also, 30% of the cases were found to be positive with culture compared to none in controls. CONCLUSION: A higher frequency of detection of H. pylori in those patients with positive antral biopsy report was seen. Also, polymerase chain reaction was found to be more sensitive than culture for detection. Thus, we conclude that detection of H. pylori in dental plaque of dyspeptic patients cannot be neglected and might represent a risk factor for recolonization of stomach after systemic eradication therapy.

Periodontal treatment needs in diabetic and non-diabetic individuals: a case-control study.

AIM: Diabetes mellitus is a chronic metabolic disorder of the carbohydrate, protein and fat metabolism, resulting in increased blood glucose levels. Various complications of diabetes have been described with periodontitis being added as the sixth complication of diabetes mellitus. The aim of this study was to assess periodontal status and treatment needs (TN) in diabetic patients and to compare the findings between diabetic and non-diabetic individuals using community periodontal index (CPI). MATERIALS AND METHODS: We evaluated the periodontal status and periodontal TN in diabetic and non-diabetic individuals in Guwahati, Assam. A total of 459 (223 diabetic and 236 non-diabetic) individuals were assessed. A person was considered to be diabetic when his blood glucose levels were above 140 mg/dl under fasting condition and 200 mg/dl 2 hours postprandially. Periodontal status was assessed using CPI. RESULTS: Periodontal destruction was found to be increased in diabetic individuals, with periodontal destruction increasing with increased blood glucose levels. The necessity of complex periodontal treatment also increased with increasing blood glucose levels. CONCLUSIONS: Individuals with diabetes are more prone to periodontal destruction, and hence, regular periodontal screening and treatment is essential in these individuals.
