[Tooth loss and periodontal status variables among policemen from Campeche, Mexico].

Objective: Identify the variables associated with periodontal status and tooth loss among a sample of adults.

Material And Methods: We carried out a cross-sectional study among 161 policemen. Our sample was representative of socioeconomics status and lifestyle among policemen in Campeche, Mexico.

Dental fluorosis prevalence and severity using Dean's index based on six teeth and on 28 teeth.

To contrast the sensitivity, specificity, and positive-negative predictive values between dental fluorosis prevalence scored on 28 (DF28) and on six permanent teeth (DF6), we undertook a cross-sectional study on 1,538 adolescents (12 and 15 years old) residing in Hidalgo State, Mexico, a naturally fluoridated (>0.7 ppm) area at an elevated altitude (>2,500 m above sea level). Dental fluorosis was scored using Deans modified index.
