Knowledge, Attitude, and Practices Regarding Maxillofacial Defects and their Prosthetic Rehabilitation among Dental Undergraduate Students in Belagavi District- A Cross-sectional Study

Abstract

Introduction: Maxillofacial defects are facial disfigurements resulting from congenital abnormalities, surgical resection of tumours, trauma, or a combination of these. The resulting deformity often leads to a difficult path of recovery with lifelong consequences, causing both physical disability and mental distress. Prosthetic rehabilitation is not only a solution to cover the physical deficit, but also a way to improve function as well as the quality of life for such patients. However, the knowledge amongst undergraduate dental health professionals about the same has been at sparse. Aim: To evaluate the knowledge, attitude, and practices regarding maxillofacial defects and their prosthetic rehabilitation amongst dental undergraduate students. Materials and Methods: A cross-sectional survey was conducted between January 2020 and June 2020, amidst the third year, fourth year undergraduate students, and interns of Belagavi city, Karnataka, India. The data was collected using a 16-item custom designed proforma, comprising of questions evaluating student’s basic knowledge about the diagnosis, treatment procedures, and treatment planning of maxillofacial defects and their prosthetic rehabilitation. Statistical analysis was done using Chi-square test in each group, using SPSS version 22 p-value <0.05 to be considered significant. Results: A total of 286 participants answered the questionnaire, of which 117 (40.9%) were interns, 116 (40.6%) were third year students, and 53 (18.5%) were fourth year students. 279 (97.6%) participants had an understanding regarding maxillofacial defects. Of those who had witnessed cases, only 18.2% had observed more than three cases (p-value <0.001). Out of respondents with treatment understanding, 184 (64.3%) answered that it required a multidisciplinary approach (p-value <0.001). 197 (68.9%) of the respondents felt that silicone was the most commonly used material (p<0.003). 165 (57.7%) answered that waxes were the most commonly used impression material (p-value <0.001). Out of the respondents awared about treatment modalities, 120 (42%) respondents majority answered that CAD-CAM would contribute the most to maxillofacial rehabilitation. Conclusion: Comprehensive understanding and clinical application of prosthodontic rehabilitation of maxillofacial defects among undergraduate students was found to be lacking. This awareness should be initiated at an early stage of the clinical training for undergraduate training programme, as it will help to understand the basic aspects involved in the prosthodontic rehabilitation of maxillofacial defects.
