title: Assessment of the prevalence of periodontal diseases and treatment needs: A hospital-based study.
abstract: BACKGROUND
  The periodontal diseases are the most prevalent oral diseases worldwide especially in developing countries like India. The objective of this cross-sectional survey was to determine the prevalence of periodontal diseases and treatment needs (TNs) in a hospital-based population.
  
  
  METHODS
  Totally, 500 men and women (15-74 years) were recruited and periodontal status of each study subject and sextant was evaluated on the basis of community periodontal index of TNs, and thereafter TN for each subject and sextant was categorized on the basis of the highest code recorded during the examination.
  
  
  RESULTS
  A total of 500 subjects (59% males and 41% females) was divided into seven age groups, that is, 15-19, 20-24, 25-34, 35-44, 45-54, 55-64, and 65-74 years and sextants were included from the 486 subjects. Healthy periodontium, bleeding on probing, calculus, shallow pockets, and deep pockets were found in 3.9%, 6.58%, 50.61%, 20.98%, and 17.90% subjects, respectively. Males were more affected with shallow and deep pockets as compared to females. Periodontal diseases in the early stages were more prevalent in the younger age groups, whereas advanced stages were more prevalent in older age groups. 17.90% subjects and 11.48% sextants need complex treatment. About 77.98% subjects and 73.15% sextants require either oral hygiene instructions or oral hygiene instructions and oral prophylaxis. Only 3.9% subjects and 15.36% sextants were healthy and needed no treatment.
  
  
  CONCLUSIONS
  Periodontal diseases were found to be 96.30% in the study population and the results indicate that majority of the population need primary and secondary level of preventive program to reduce the chances of initiation or progression of periodontal diseases thereby improving their systemic health overall.
