Knowledge and application of antimicrobial photodynamic therapy among restorative dentist in Saudi Arabia

The aim was to identify the restorative dentist, knowledge and application of Antimicrobial photodynamic therapy (aPDT) in dental practice; and to provide an overview of the potential challenges faced by restorative dentists (RD) in Saudi Arabia.

A 15-item cross sectional study questionnaire was distributed through online portal to assess the knowledge, and practice of RD towards aPDT and its practice. The questionnaire consisted of 3 sections, exploring the demographics of participants, knowledge, application and perception of aPDT using yes/no response and Likert scale. Response means, frequencies, and chi-square tests to compare subgroups based on gender, education level, and practice experience.

Out of 500 participants, 375 completed the survey forms (75% response rate). The majority was male (68%) with a mean age of 46 years. Respondents demonstrated a moderate level of knowledge (60.5%). Only 33% expressed confidence in aPDT as a standalone treatment, while 67% showed limited referrals to specialists. However, 88.5% expressed interest in receiving training and attending workshops for aPDT therapy. Education and experience significantly influenced overall knowledge question responses (p = 0.031).

Majority of restorative dentists demonstrated a moderate understanding of the role of aPDT in dentistry. More than two thirds of respondents (77%) believed that aPDT is an effective adjuvant therapy. Increased experience (> 10 years) and education (Post-graduates) showed higher application of aPDT. The study reveals the potential for incorporating aPDT knowledge into restorative dental practices, particularly among general dentists.
