Abstract

Objective: To determine the level of knowledge of Oral Cancer (OC) of dental surgeons in Los Rios Region in the year 2017. Materials and methods: A descriptive, cross-sectional study consisting of a survey containing 24 multiple-choice questions was conducted and applied in person to 102 public practice dentists of Los Ríos Region, between March-July 2017. Participants were previously informed that the survey was voluntary, anonymous and confidential. Characterization data from the population was collected and the variable “Knowledge of Oral Cancer” along with its subsections on OC epidemiology, etiopathogenesis, diagnosis, treatment/complications and prognosis/prevention were measured. Tabulated data were analyzed through descriptive statistics. Results were presented through a passing percentage (60% minimum for approval). Results: 100 surveys were answered (with a 98% response rate). Knowledge of OC averaged a 77% passing rate among the participants: 63% for the epidemiology section, 78% for etiopathogenesis, 86.5% for diagnosis, 64% for treatment/complications, while OC prevention resulted in a 75% passing rate. Conclusion: A high percentage of dental surgeons in Los Rios Region demonstrated a satisfactory knowledge of the etiopathogenesis, diagnosis and prevention of OC. However, a low percentage responded correctly regarding the epidemiological factors, treatment and complications. It is highly recommended to follow the same research methodology in other regions across Chile in order to analyze results at a national level with a new approach, so as to properly guide future professional training programs.
