Influence of the teaching program on the learning in knowledge and practice of osteonecrosis of the jaws produced by antireasorptives in dental students of the Principality of Asturias (Spain)

BACKGROUND: This study aims to evaluate the influence of changes in the teaching contents on medication-related osteonecrosis of the jaw may have on the knowledge and the capacity for practical case resolution about this pathology. MATERIAL AND METHODS: A cross-sectional descriptive study was conducted through a survey divided into four sections: degree of means of knowledge acquisition, habitual practice and ability to solve clinical cases. The total number of respondents (n = 225) was divided into two groups: Group A (Year 2015-2016) and Group B (Year 2016-2017). The students in Group B received more teaching content on the subject than group A. RESULTS: A total of 175 survey responses were collected. The internet was the preferred tool for continuing education in both groups. The best known bisphosphonates (BPs) were Alendronate (Fosamax®: 56.9% Group A, 67.5% Group B) and Zoledronic Acid (Zometa®: 56.9% Group A, 51.8% Group B). A low percentage of students (37.9% Group A, 43.4% Group B) acknowledged the existence of other drugs that could also cause osteonecrosis of the jaws. Regarding the correct resolution of practical cases, the respondents of Group B reached a significantly higher score (5.67) than the score observed in Group A (4.04). CONCLUSIONS: Training on medication-related osteonecrosis among dental students is susceptible to improvement. Introducing minor changes in the teachings allows this goal to be successfully achieved. Key words:Osteonecrosis of the jaw (ONJ), bisphosphonate-related osteonecrosis of the jaws (BRONJ), medication-related osteonecrosis of the jaw (MRONJ), dental education.
