Purpose: The purpose of the study was to evaluate the current literature in order to
determine the risks for chronic adult periodontal disease.
Methods: Two main research strategies were carried out to obtain potentially relevant
articles, pertaining to our area of interest. Using predetermined research criteria:
A search of Ovid Medline and PubMed of relevant publications, dating from 1966 to
2006 was performed in both databases. 59 articles were obtained by the search and
additional 12 articles were obtained by other search methods. The 71 articles were
reviewed according to our research criteria, and only 6 articles were found to be relevant.
Results: Risks associated with chronic periodontal disease are smoking (OR 3.58-14.51),
age (OR 8.67), tooth brushing (OR 5.77), teeth mobility (OR 4.9), mental illness (OR
5.32), vitamin D receptor gene polymorphism (OR 2.73), alcohol (OR 1.36), irregular
dental visits and low education.
Conclusion: There is evidence to support that smoking, age, tooth brushing teeth
mobility, mental illness, vitamin D receptor gene polymorphism, alcohol, irregular dental
visits and low education are risks for chronic adult periodontal disease.
Periodontitis can be defined as “an inflammatory disease of the supporting tissues of the
teeth caused by specific microorganisms , resulting in progressive destruction of the
periodontal ligament and alveolar bone with pocket formation, recession or both”.
Chronic periodontitis is a sub-classification of periodontitis. It is prevalent in adults but
can also occur in children. Apart
