Introduction: Community interventions make it possible to promote health and prevent disease in the population. Objective: Describe the diagnoses and treatments made by dental students at the Multidisciplinary Research and Service University Camp. Methods: A qualitative epidemiological study was designed for the district of San Pablo de Pillao, Huánuco province, Peru. The participants were teachers and students from the School of Human Medicine, Dentistry, Nutrition and Psychology. Of the total 250 subjects attending the sessions, 95 adults were cared for at the dental service. The educational sessions conducted dealt with the topics of "anemia and malnutrition", "diarrheal diseases", "respiratory infections", "alcoholism and violence", "growth and development", "breastfeeding" and "oral health", as well as a campaign about diagnosis and treatment of oral disorders. Data analysis was performed on Microsoft Excel. Results: Of the total 95 adult residents cared for, 6.3% were totally edentulous and 40% were partially edentulous. Of the dentate subjects, 97.3% had dental caries with a mean DLRP index (sum total of decayed + lost + restored permanent teeth) of 2.08 ± 1.56. As to periodontal status, 38.9% had severe gingival inflammation. A total 35 restorations, 28 exodontias and 8 prosthesis adjustments were performed on adult patients. Adults and children alike received fluoridation and attended five educational health promotion sessions. Conclusions: Dental caries and gingival disease were highly prevalent. The main therapeutic actions performed in the camp were restorations and exodontia.
