Oral cancer and precancer in Oral Pathology and Medicine curricula of Mexican dental schools.

Objective: To identify the teaching-learning process characteristics of Oral Pathology and Medicine (OP&M) related to oral potentially malignant disorders (OPMDs) and oral cancer (OC), in the dental schools' curricula in Mexico, to analyze the approach given to this topic worldwide, and to provide the possible solution strategies.

Materials And Methods: Questionnaires were sent to OP&M deans and professors from public Mexican Universities to explore the curriculum and academic profile of the dental schools. The recommendations gathered from a workshop with expert professors on the challenges in OPMD/OC teaching were reported.

Clinico-pathologic conference: case 4.

A 45 years old male patient presented with an asymptomatic right mandibular mass that extended from the angle to the premolar area. It had been present for 3 months at the time of the initial presentation. Panoramic radiograph revealed an ill-defined unilocular radiolucency.

Multiple dens invaginatus, mulberry molar and conical teeth. Case report and genetic considerations.

Dens in dente, also known as dens invaginatus and dilated compound odontoma, is a malformation that can occur on primary, permanent, or supernumerary teeth that is characterized by a deep invagination of the surface of a crown or root covered with enamel. This abnormality in tooth morphology generally affect the maxillary lateral incisors but several cases of multiple dens invaginatus have been reported in the literature. A 15 year-old female patient is reported here presenting five dens invaginatus: four in the permanent mandibular incisors and one in the permanent, maxillary left central incisor, additionally the following dental findings were observed: a permanent mandibular left mulberry molar, molarization of some premolars, several microdontic conoid teeth, retention of five primary teeth, absence of several permanent teeth germs, a macrodontic molar with abnormal roots and several periapical radiolucencies associated to the dens invaginatus.

Leiomyomatous hamartoma: report of two cases and review of the literature.

Two cases of leiomyomatous hamartoma (LH) in patients of Latin ancestry are reported here. The first lesion was detected on the incisive papilla of a 19-year-old woman; this is an unusual age because these lesions are commonly observed during the first years of life.
