[Frequency and clinical outcome of odontogenic cervicofacial infection].

Objective: To measure frequency, mortality, hospitals stay and the requirement of attention in the intensive care unit (ICU) of patients with cervical infections.

Methods: A descriptive, observational and transversal study was carried out. We analyzed the database of patients admitted to Emergency Room of High Specialty Hospital, with cervical and facial infection with odontogenic origin, during a year period.

[Risk factors for dental fluorosis in children between 6 and 15 years old].

Objective: To identify risk factors for dental fluorosis in children between 6 and 15 years.

Methods: A cross-sectional survey in 1284 students between 6 and 15 years from four living areas. Presence and degree of dental fluorosis were investigated by using the classification of Dean, tooth decay and variables like source of water consumption, juices, prepared gaseous drinks, tea, types of dental paste used, and periodic applications of fluoride.

[Prevalence of dental fluorosis in children between 6 to 15 years old].

Background: dental fluorosis is a defect in the formation of the enamel by high fluoride concentrations during tooth development. It produces hypomineralization of the enamel by increasing the porosity, thus exposing the tooth to decay.

Objective: to determine the prevalence and severity of fluorosis in children aged 6 to 15 years.
