Introduction: Periodontal disease is preventable and affects the general population. The objective of this study was to examine the relationship between the diagnosis and treatment of patients in the periodontics and oseointegration clinics of the Universidad Cooperativa de Colombia, Bogotá branch, between 2018 and 2021.Method: This was a descriptive correlational study. A total of 262 clinical records with informed consent were analyzed. Records with diagnoses according to the Armitage classification of 1999, deletions, alterations, or lacking the instructor's signature were excluded. The information was organized in a Microsoft Excel database for statistical analysis. Qualitative variables were presented as frequencies and percentages, while quantitative variables were expressed as means and standard deviations. The chi-square test was used to correlate diagnosis and treatment with a 95% confidence level. Results: Out of the 245 analyzed clinical records, 64.5% were women. The majority belonged to socioeconomic stratum 3 (44.1%), followed by stratum 2 (41.2%). Arterial hypertension (14.4%) was more frequent in patients aged 45 to 64, followed by diabetes (2.2%) within the same age range. 90.6% of the patients did not present periodontal disease at the time of consultation. The most common diagnosis for both men (25.3%) and women (21.7%) was stage I, grade A periodontitis. Significant differences were found between the frequency of systemic diseases and socioeconomic strata (p < 0.001), as well as between periodontal treatments and age groups (p < 0.01). Conclusions: It is important to consider age and socioeconomic stratum in the epidemiology of periodontal disease, as well as systemic diseases and socioeconomic factors.
