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.

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.

Pathological findings in a sample of Mexican pediatric patients. Clinical and radiographic survey.

Aim: The findings of a clinical-radiological review of 467 children attending the Oral Diagnosis Clinic of the Facultad de Odontología, UNAM, Mexico, are presented.

Methods: All patients were clinically reviewed, clinical history was taken, and an orthopantomogram obtained by last year dentistry students. Patients and radiographs were then reviewed by the panel and all alterations in teeth, soft tissues and bone were recorded.

Multiple supernumeraries in a non-syndromic patient.

Presence of supernumerary teeth (ST) in non-syndromic patients is an exceptional event. The aim of this article is to present an unusual case of a non-syndromic 12 years old girl with 12 ST In the reported case supernumeraries were found in three quadrants and the most common ST were bicuspids. All ST were surgically excised and occlusion and functionality was restored with prosthetic appliances.

Scanning electron micrographic features of a giant submandibular sialolith.

To recognize recently appearing mineralization phenomena, one must study the external surface of the sialoliths, since it is not possible to study them in the central portions of sialoliths. The authors examined the external surface of a sialolith by scanning electron microscopy and analyzed its microstructures. The study revealed the presence of numerous microstructures of different shapes (nodular, laminar, reticular, microgranular, and multinodular) and variable size arranged in a haphazard fashion.

Frequency of supernumerary teeth in Mexican population.

Supernumerary teeth (ST) are a not uncommon developmental anomaly which appears in 0.3 to 3.8 percent of the population.
