ABSTRACT

OBJECTIVE: To determine the frequency of oral squamous cell carcinoma (OSCC) associated or not with oral potentially malignant disorders (OPMD), and the epidemiological profile and traditional risk factors in Latin America. METHODS: A retrospective observational study was conducted in 17 Latin American centres. There were included cases of OSCC, analysing age, gender, OSCC and their association with previous OPMD. Clinicopathological variables were retrieved. The condition of sequential-OSCC versus OSCC-de novo (OSCC-dn) was analysed concerning the aforementioned variables. Quantitative variables were analysed using Student's t-test, and qualitative variables with chi-square. RESULTS: In total, 2705 OSCC were included with a mean age of 62.8 years old. 55.8% were men. 53.75% of the patients were smokers and 38% were common drinkers. The lateral tongue border was the most affected site (24.65%). There were regional variations in OPMD, being leukoplakia the most frequent. Of the overall 2705 OSCC cases, 81.4% corresponded to OSCC-dn, while s-OSCC were 18.6%. Regarding lip vermillion SCC, 35.7% corresponded to de novo lip SCC and 64.3% were associated with previous OPMD. CONCLUSIONS: In Latin America, OSCC-dn seems to be more frequent with regional variations of some clinical and histopathological features. Further prospective studies are needed to analyse this phenomenon.

ABSTRACT

El bruxismo nocturno es una parafunción caracterizada por contracciones musculares repetidas de la mandíbula. Esto se transforma en una condición patológica cuando el paciente presenta daño dentario. La mayor actividad muscular fue encontrada en el estadio dos del sueño y durante el despertar. El bruxismo es un fenómeno controvertido, pero existe consenso sobre su etiología multifactorial

ABSTRACT

Existe una gran cantidad de patologías que asientan sobre la mucosa bucal, cuyo origen está relacionado con materiales o instrumental utilizado durante la práctica odontológica diaria. Ellas van desde erosiones hasta ulceraciones o lesiones crónicas como las pigmentaciones y leucoplasias, entre otras. En este trabajo se propone una clasificación de estas lesiones según su etiopatogenia
