Orthopantomography Detection of Atheroma Plaques and Its Relationship with Periodontal Disease and Missing Teeth

Background. The aim of this study is to determine the atheromatous plaques’ prevalence in orthopantomography and their relationship with periodontal disease and missing teeth. Material and Methods. Orthopantomographs of 1,254 patients over 18 years of age from Clínica Arlanza in Lerma, Burgos, were examined between 2017 and 2021. A Planmeca ProOne® orthopantomograph (68 kV, 7 mA, and 10 sg) was used. Statistical analysis was carried out using SPSS Statistics® version 25. The results of the categorical variables were described as frequencies (%). Contingency tables were made with the qualitative variables, and the chi-square test was applied to study the relationship among them. The measure of statistical power used was the relative risk (RR), which was described with its respective 95% confidence interval (CI). Student’s t-test was applied to study the relationship between the qualitative variable “presence or absence of atheroma plaque” and the quantitative variable “number of teeth.” Results. A 6.2% prevalence of atheroma plaques was obtained from 1,079 selected X-rays. The risk in patients with periodontal disease increased as periodontal disease worsened. The risk in patients with periodontal disease increased as periodontal disease worsened as follows: healthy patients vs. periodontal patients with less than 30% bone loss in radiography: RR 0.434, 95% CI 0.181–1.041, p=0.053 healthy patients vs. patients with between 30%–60% bone loss: RR 0.177, 95% CI 0.075–0.418, p
