Anti dermatophytic therapy: prospects for the discovery of new drugs from natural products

Millions of people and animals suffer from superficial infections caused by a group of highly specialized filamentous fungi, the dermatophytes, which only infect keratinized structures. With the appearance of AIDS, the incidence of dermatophytosis has increased. Current drug therapy used for these infections is often toxic, long-term, and expensive and has limited effectiveness; therefore, the discovery of new anti dermatophytic compounds is a necessity. Natural products have been the most productive source for new drug development. This paper provides a brief review of the current literature regarding the presence of dermatophytes in immunocompromised patients, drug resistance to conventional treatments and new anti dermatophytic treatments.

Plaque control improves the painful symptoms of oral lichen planus gingival lesions. A short-term study

BackgroundLichen planus is a mucocutaneous disease with manifestation in the oral mucosa, the gingiva being one of the most affected regions. In some cases, the lesion may be painful and lead to fragility of the tissues, so that precise diagnosis and adequate treatment are indispensible factors for improving the clinical condition. The aim of this study was to evaluate the effectiveness of plaque control in the improvement of clinical features and painful symptoms of oral lichen planus with gingival involvement.MethodsTwenty patients diagnosed with gingival lichen planus confirmed by histopathological examination were selected. The patients were evaluated by a trained examiner, with regard to the clinical features of the lesions [Index of Escudier etal. (Br J Dermatol, 157, 2007, 765)]; painful symptoms (Visual Analog Scale); and periodontally, as regards the visible plaque and gingival bleeding indices. Periodontal treatment consisted of supragingival scaling and oral hygiene instruction, with professional plaque removal afterward for a period of 4weeks. The entire sample was evaluated at the baseline and at the conclusion of treatment, and the results were analyzed by the Wilcoxon nonparametric test.ResultsThe data demonstrated that the majority of patients were women (90%), with a mean age of 55.9years. Periodontal treatment resulted in statistically significant reduction (P<0.05) in the periodontal indices, with consequent improvement in the clinical features and painful symptoms of the lesions.ConclusionsIt was demonstrated that plaque control was effective in improving the clinical features and painful symptoms of oral lichen planus with gingival involvement.

PREDICTABLE INTERPROXIMAL TISSUE REMOVAL WITH A SURGICAL STENT

The correction of diastemas in the anterior region with composite resin is considered to be practical and conservative. Harmony between the restorative material and the periodontium is necessary to achieve satisfactory functional and esthetic results. Whenever excessive gingiva occurs in the interproximal region, removal is necessary to avoid excessively contoured restorations. A predictable technique is described to conservatively remove interproximal tissue in situations in which crown lengthening is required to treat bilateral diastemas. A surgical template based on the diagnostically waxed cast was produced to serve as a reference during periodontal surgery.

Doença periodontal em cães

Periodontal disease affects the periodontum which are tissues that support and protect the tooth and are composed by the gingiva, alveolar bone, cementum and periodontal ligament. Lesions in the periodontum have as main etiologic agent the presence of plaque or biofilm, which is formed in 24 hours and, basically, it consists of microorganisms surrounded by some bacteria rich matrix products and salivary glycoproteins. Gingivitis is the first clinical manifestation of periodontal disease and it is reversible if the etiologic agent (plaque) is removed. However, if it is not treated or controlled, it will lead to an irreversible periodontitis, and even evolve into alveolar bone, tissue destruction and, eventually, tooth loss

Innovation in pediatric surgery: the use of ultrasonic CVD tips: case report

The non-eruption of teeth due to highly keratinized gingival mucosa is a frequent event in the pediatric dentistry, which harms the oral aesthetics and function. A surgical excision of the involved area is indicated, exposing the non-erupted tooth. This procedure involves anesthesia and cutting instruments that may increase the fear and anxiety in young patients. The use of new technologies has avoided these instruments and has promoted more comfort to the patients. This study presents clinical cases in which gingivectomy was performed using the innovative method with an ultrasound-activated CVD tip. It was concluded that this method presented effectiveness, promoted more comfort, and less fear to the patients, making its use a viable alternative to pediatric surgery.

Comparison between periodontal disease and a gingival carcinoma with emphasis on radiographic imaging

The majority of published papers deal mainly with prevalence, pathogenesis and treatment of squamous cell carcinoma of the gingiva (SCCG). On the other hand, little is discussed about the comparison between periodontal disease and gingival carcinoma with emphasis on radiographic imaging. In this case report we discuss the importance of the radiographic aspects in inflammatory periodontal disease and SCCG. This case report shows the importance of differentiating a localized severe periodontal disease and SCCG considering the radiographic aspects of the inflammatory bone loss and tumoral bone loss. The oral health care providers need to be familiar with the radiographic imaging of periodontal disease and SCCG.

Tratamento do sorriso gengival: como estabelecer proporção e harmonia

The etiology of gingival smile is multifactorial and the correct diagnosis eill determine a successful treatment planning. Altered passive eruption occurs during the final stages of tooth eruption, when apical migration of the periodontal tissues does not occur, resulting in a distance > 2mm between the alveolar crest and the cement-enamel juncrion. This change leads to the shortening of the clinical crown and even further may lead to excessive gingival exposure. For treatment, there is a necessity for the combined removal of gingiva and bone tissue. This article discusses the literature on the issue and reports a case where periodontal plastic surgery was performed for the correcrion of a gingival smile.
