Association Between Periodontal Disease and Missing Teeth With Systemic Conditions
Objectives: The purpose of the present study was to investigate the correlation between periodontal disease and various systemic medical conditions recorded in the patient’s medical health questionnaire as well as to examine the link between tobacco use with bone loss and missing teeth.
Methods: In this retrospective case-control study, 3,600 dental charts were randomly selected from the University of Minnesota School of Dentistry records. Adult patients with at least six remaining teeth in the dentition with a complete medical history and full-mouth radiographs were included in the study to determine the percentage of bone loss (mild: <25%, moderate 26-50% and severe >50%) and the number of missing teeth. Demographic characteristics of the patients such as age and gender were also recorded. Univariate analyses (Fisher’s exact test) and adjusted analyses (logistic regression) were utilized to evaluate the association of various systemic medical conditions and tobacco use with the severity of bone loss and number of missing teeth.
Results: A total of 3,511 dental charts with complete data were evaluated along with full-mouth radiographs. The sample mean age was 54.22±17.78 years and included 52.8% males. There were 20.4% patients diagnosed with moderate and severe bone loss and the mean number of missing teeth was 3.58±3.94. Univariate analysis showed that 21 systemic conditions and tobacco use were significantly associated with bone loss (p=0.001-0.044), while seven of these factors maintained statistical significance after adjusting for age, gender and smoking status (p=0.001-0.034). Similarly, 13 conditions and tobacco use were significantly related to the number of missing teeth (unadjusted p=0.001-0.042) and six of these remained significant after adjustment (p=0.001-0.048).
Conclusions: Within the limitations of this retrospective chart review study, a number of systemic conditions such as diabetes mellitus and osteoporosis as well as smoking status are significantly associated with the severity of bone loss and the number of missing teeth.
