Study on frequency of dental developmental alterations in a Mexican school-based population.

Background: The aim of this study was to know the distribution of dental developmental alterations in the population requesting stomatological attention at the Admission and Diagnosis Clinic of our institution in Mexico City.

Material And Methods: We reviewed the archives and selected those files with developmental dental alterations. Analyzed data were diagnoses, age, gender, location and number of involved teeth.

MUC-1 expression in pleomorphic adenomas using two human milk fat globule protein membrane antibodies (HMFG-1 and HMFG-2).

Unlabelled: Pleomorphic adenoma (PA) is the most common salivary gland tumor and its microscopic features and histogenesis are a matter of debate. Human milk fat globule protein membrane (HMFG) monoclonal antibodies (MoAbs) comprise a set of antibodies against the mucin 1 (MUC-1) protein detected in several salivary gland tumors.

Objective: The aim of this study was to assess the immunoexpression of the PA neoplastic cells to MUC-1 protein using HMFG-1 and HMFG-2 MoAbs, contrasting these results with those from normal salivary gland tissue.

Scanning Electron Microscopic Study on the Fibrillar Structures within Dentinal Tubules of Human Dentin.

Introduction: Pulp biology is central to the whole tooth, and knowledge on its microstructure is changing with new studies. This study presents certain microfibrillar structures found within the dentin tubules of human teeth connecting dentin tubules and odontoblastic processes.

Methods: We analyzed the crowns of 30 noncarious, human teeth.

Toxicity test of a dental commercial composite.

Background: International rules must be followed for testing biosecurity in dental materials. A new brand of restorative material appeared in the market and regulations indicated that it should be tested for toxicity.

Objectives: The aim of this study was to determine the 90-day sub chronic toxicity of one triethylene glycol dimethacrylate containing composite (MEDENTAL Light-Cure Composite™) orally administered to rats according to Organization for Economic Co-Operation and Development no.

Review of the literature on necrotizing sialometaplasia and case presentation.

The aim of this article is to report a case of necrotizing sialometaplasia with long-term follow-up. A case of necrotizing sialometaplasia in a 37-year-old man with clinical documentation on the progress during a 2-year follow-up is presented. Data from an extensive review of the literature including clinical, imagenologic, and microscopic features are provided.
