Cytological Screening Model of Normal Oral Mucosa Exposed to Carcinogens: A Pilot Study.

Introduction: Oral cytopathology is able to detect incipient cellular alterations, but it is not routinely applied to this purpose. We aimed to establish a model to screen individuals with no oral lesion exposed to smoking/alcohol, by means of the nuclear area, cell proliferation rate, and analysis of genetic damage.

Methods: In this cross-sectional pilot study, 90 patients were allocated into 3 groups: oral cancer group (patients with oral squamous cell carcinoma), tobacco/alcohol group (patients without oral lesions and exposed to these risk factors), and control group (individuals with no lesion and not exposed to tobacco and alcohol).

Tooth fragments lodged in the lower lip after traumatic dental injury: a case report.

Dental fractures are common trauma complications in the oral cavity. The efficient diagnosis and treatment of dental injury are important elements in clinical dentistry. This article describes a case study of trauma in central maxillary incisors with tooth fragments lodged in the lower lip.

AgNOR quantification in cells of normal oral mucosa exposed to smoking and alcohol. A cytopathologic study.

Objective: To evaluate cell proliferative activity by counting and measuring argyrophilic nucleolar organizer regions (AgNORs) per nucleus in cell smears from mucosa clinically exposed to smoking and alcohol.

Study Design: Group 1 (control) consisted 17 patients, group 2 (smoking) of 25 and group 3 (smoking and alcohol) of 18. Cell smears collected from the mucosa of the lower lip, border of the tongue and floor of the mouth underwent AgNOR staining.
