Abstract
Phonetics plays a major role in the fabrication of prostheses. This study aimed to assess the knowledge of students regarding the role of phonetics in denture fabrication and to improve the educational process and the clinical application. The study was conducted at the College of Dentistry, Imam Abdulrahman Bin Faisal University, and involved a survey of 344 dental students and interns. The questionnaire contained 20 questions and was divided into three sections: general knowledge, clinical correlations, and clinical evaluations. The data were collected and analyzed statistically using independent
t
-tests, one-way ANOVA, and Tukey’s post hoc tests. The response rate was 100%. Male and female students only differed significantly in terms of their scores for answers to general knowledge questions, with females achieving better results (
p
= 0.023). General knowledge varied significantly between fourth-year students and all other levels (
p
< 0.001), and fifth-year students and interns (
p
= 0.027). The clinical correlations varied significantly between fourth-year students and interns (
p
= 0.01), whereas the clinical evaluations varied between all the academic years and interns (fourth-year,
p
< 0.001; fifth-year,
p
= 0.003; and sixth-year,
p
= 0.017). The interns obtained the highest scores in all sections. There was a lack of awareness among dental students of some aspects of the role of phonetics in denture fabrication. The study highlights the deficiencies that need to be addressed and the need for adjustments to the curriculum related to removable prosthodontics in order to improve the knowledge of students regarding the role of speech in denture fabrication.
