Evaluation of 2 techniques of epithelial removal in subepithelial connective tissue graft surgery: a comparative histological study

PURPOSE: Subepithelial connective tissue grafts (SCTGs) are commonly performed for the treatment of gingival recession due to their high predictability. This study evaluated and histologically compared connective tissue grafts in terms of the presence of epithelial remnants and composition of the tissue types that were present (epithelium, lamina propria, and submucosa).METHODS: Ten patients underwent epithelium removal using 2 different techniques: the use of a blade (group B) and through abrasion (group A). Twenty samples were collected and each tissue type was analyzed histologically in terms of its area, thickness, and proportion of the total area of the graft.RESULTS: In 4 samples (40%) from group B (n=10) and 2 samples (20%) from group A (n=10), the presence of an epithelial remnant was observed, but the difference between the groups was not statistically significant (P>0.05). Likewise, no statistically significant differences were observed between the groups regarding the area, mean thickness, or proportion of the total area for any of the tissue types (P>0.05).CONCLUSIONS: Histologically, SCTGs did not show statistically significant differences in terms of their tissue composition depending on whether they were separated from the epithelial tissue by abrasion or by using a blade.

Fitoterapia: dos canteiros ao balcão da farmácia / Phytotherapy: from greenhouses to drugstore’s bench

Introdução: Com a recente instituição do Programa Nacional de Plantas Medicinais e Fitoterápicos dentro do Sistema Único de Saúde (SUS) (Portaria interministerial 2.960/2008), foi confirmado o reconhecimento da eficácia de fármacos fitoterápicos na prática clínica, sobretudo no tratamento e na prevenção de afecções de menor severidade. Como em outros campos das ciências médicas, a odontologia também deve se apropriar desse recurso para o tratamento de populações, para as quais o acesso aos medicamentos industrializados é dificultado pela condição socioeconômica desfavorável. Diferente do senso comum que permeia a sociedade urbana, a fitoterapia é uma modalidade terapêutica com fundamentação científica e com reconhecida aplicabilidade. Conclusão: Esta revisão busca trazer ao cirurgião-dentista informações que lhe permitam conhecer melhor a fitoterapia.

Introduction: Recently, with the institution of the National Program of Medicinal Plants and Phytotherapywithin the Brazilian Unified Health System (SUS) (interministerial directive 2960/2008), the efficacy ofphytotherapics in the clinical practice was recognized, mainly for the treatment and prophylaxis of lesssevere diseases. As well as in other medical fields, Dentistry must exploit this tool for the treatment of poorpopulations, which has no access to industrialized medication. Unlike the common sense that permeatesthe urban society, phytotherapy is a therapeutic modality based on scientific comprobation and recognizedapplicability. Conclusion: This review intends to bring some new data to dental surgeons, favoringa better accepting of the phytotherapy.
