Decision-making in clinical dental practice is based on the use of periodontal parameters such as the level of alveolar bone and clinical attachment, disregarding the patient's age, which may result in unnecessary extractions of teeth that still have periodontal support capable of maintaining the element. tooth inserted into the socket, reaching 70 years of age with at least 1/3 of the root root length with bone support. The objective of this systematic review was to verify the level of alveolar bone or periodontal clinical attachment in an adult population, throughout life, identifying the prevalence of individuals or periodontal sites that present clinical attachment loss (CAL) ≥ 1, 2, 3, 4, 5, 6, 7, 9 mm and the difference in periodontal support between the remaining and extracted teeth. The method used was a strategic search in PubMed, Embase, Lilacs, Google Scholar, CAPES catalog, of cross-sectional epidemiological studies (epidemiological surveys) using the population-based sample or cohort studies, published from 1940 to 2020, in any language. The studies were exported to EndNote 20.3, with data selection and extraction performed by two masked reviewers and risk of bias assessment by the JBI tools. Statistical treatment was performed using the free software R Project 1.3 and RevMan 5. The results were the identification of 9952 studies, 740 excluded in the identification, 8996 in the screening, leaving 205 eligible, and 21 articles were included in the review. In the meta-analysis, a summary prevalence measure of individuals with CAL ≥ 3 of 0.86% (95% CI, 0.71-0.94) was obtained; CAL ≥ 4 of 0.18-0.47, CAL ≥ 5 of 0.40% (95% CI, 0.19-0.67), CAL ≥ 7 of 0.06 (0.02-0.13) by age 20-40, 41-60, 71+ years. There was a significant association between CAL insertion loss ≥ 1 mm and study location (american continent), with 91.41% of the real variance of the studies explained by age. The range of CAL in the < 50 years group was from 0.62 (0.03) to 2.39 (1.27) mm, and > 50 years, from 1.46 (0.05) to 4.90 (1.70) mm. The ABL (Alveolar Bone Loss) range was from 20 to 79 years from 0.2 (0.03) to 8.8 (0.5) mm and from 31 to 65 years from 1.32 (0.36) to 2.81 (0.93) mm. The summary measure of mean difference in CAL between extracted and remaining teeth was 1.84 (1.14-2.54) mm, with no a significant difference between the age subgroups < 50 years and 50 years and over. Most studies were rated as high risk of bias and the GRADE assessment of the confidence level of the evidence was rated as very low. The conclusion was that the rate of bone loss per decade of life, from the age of 20 onwards, is fundamental for the assessment of the progression of periodontal disease and should be maintained between 0.38 and 1.5 mm in order to reach 70 years of life with a tooth showing periodontal support. Further longitudinal studies are recommended to assess age and social determinants as confounders of the relationship between periodontal disease and CAL or ABL outcomes.
