BACKGROUND: Data from national surveys regarding the periodontal status of the adult population in Latin America are scarce. The aim of this study assesses the prevalence and extension of clinical attachment loss (AL) in the adult population of Chile. Age, sex, and sociodemographic and behavioral differences in the prevalence of clinical AL are also examined.
METHODS: A stratified, multistage probability design formula was used to separate the adult Chilean population into two age cohorts. The first group consisted of 1,092 young adults (age range: 35 to 44 years), and the second group consisted of 469 adult seniors (age range: 65 to 74 years). All subjects were examined to measure clinical AL. The research also included an evaluation, conducted through oral interviews, of social and health aspects of the subjects. Clinical AL was measured in all teeth surfaces, excluding third molars. Results were analyzed using a multivariable model and logistic regression.
RESULTS: A total of 93.45% of the young adults had ≥ 1 site with clinical AL >3 mm compared with 97.58% of the adult seniors, with an average of 6.51 and 15.81 missing teeth, respectively (P <0.05). The number of sites with severe clinical AL (>6 mm) was 38.65% in young adults and 69.35% in senior adults (P <0.05). Clinical AL was significantly higher in males than in females (P <0.05). The multivariate analyses identified that the main risk indicators for clinical AL >6 mm in ≥ 1 site were: age (65 to 74 years), sex (male) low education level (<or=12 years of education), and smoking (P <0.05).
CONCLUSION: The adult population in Chile shows a high prevalence and extension of clinical AL with age, sex, education level, and smoking as the main risk indicators of severe clinical AL in this population.
