Esthetic recovery of smile using composite resin and "biological posts" and crowns.

The recovery of teeth that have been extensively destroyed by dental caries can be achieved through direct and indirect restorative procedures. This paper presents a case of the esthetic and functional recovery of permanent maxillary incisors with extensive dental caries in an adolescent patient through the use of a composite resin and "biological posts and crowns". A case report was drafted to describe the direct restoration of central maxillary incisors using composite resin and endodontic treatment of the lateral maxillary incisors, the construction of dentinal posts, the adaptation and cementing of the posts to the root canals, preparation and molding of crown portions, model construction, the choice of extracted teeth and the making and cementing of "biological crowns".

Oral mucosa alterations in a socioeconomically deprived region: prevalence and associated factors.

This study aimed to evaluate the prevalence and factors associated with oral mucosa alterations in patients from Vale do Jequiti-nhonha, Brazil. The sample consisted of 511 patients of both genders. Questionnaires were used to obtain information about patient gender, age, race, systemic disease state, medication use, cigarette use and alcohol consumption.

Immunoexpression of hMSH2 and hMLH1 in oral squamous cell carcinoma and its relationship to histological grades of malignancy.

Background: The aim of this study was to describe the human mutS homolog 2 (hMSH2) and human mutL homolog 1 (hMLH1) immunoexpression in different areas of oral squamous cell carcinoma (OSCC) - central/superficial (C/S) and invasive tumor front (ITF) - in an attempt to verify if the histological grade of malignancy interferes in this expression.

Methods: Forty-six samples of OSCC were analyzed histologically. Twenty-six cases (56.

Tobacco and inflammation effects in immunoexpression of hMSH2 and hMLH1 in epithelium of oral mucosa.

Background: Both hMSH2 and hMLH1 are integrated in the DNA mismatch repair (MMR) system. Reduced expression of these proteins has been reported in head and neck carcinoma; however, few studies have examined the normal levels of these proteins in oral tissues or investigated factors which could interfere with this expression. The aim of this study was to detect the expression pattern of hMSH2 and hMLH1 in normal oral mucosa and to correlate this with demographic data, smoking and local inflammation.

Odontogenic tumors: a study of 340 cases in a Brazilian population.

Background: The aim of this study was to determinate the relative frequency of odontogenic tumors (OTs) in a Brazilian population and to compare this data with previous reports.

Methods: We reviewed the achieves of 19 123 specimens from oral pathology laboratory of Universidade Federal de Minas Gerais, from 1954 to 2004. Using the criteria of histologic typification published by the World Health Organization in 1992, we classified the OTs.
