Laser Technology Utilization and Its Rolein Restorative and Cosmetic Dentistry

Abstract

Introduction: Since its introduction into dentistry in the 1960s, laser technology has evolved from experimental
tools to advanced systems with applications in both soft- and hard-tissue procedures. In restorative and cosmetic
dentistry, lasers are used for cavity preparation, gingival contouring, tooth whitening, and precise soft-tissue
management, offering high precision, minimal invasiveness, and faster recovery. Objectives: The objective
of this study was to evaluate the knowledge, attitudes, and practices (KAPs) of dental students, interns, and
practicing dentists toward the utilization and clinical role of laser technology in restorative and cosmetic dentistry.
Methods: This cross-sectional study was conducted between July 2025 and December 2025 to assess the KAPs
regarding the utilization and role of laser technology in restorative and cosmetic dentistry among dental students,
interns, and practicing dentists. Data were collected through a self-structured, anonymous, self-administered
questionnaire in English. The questionnaire was developed after reviewing relevant studies conducted in Saudi
Arabia and internationally to ensure content validity. Results: A total of 678 responses were analyzed. Participants
were predominantly aged 17–24 years (48.4%) or 25–29 years (46.8%), and nearly half were undergraduate
students (47.8%). Although 97.6% of participants reported knowing what a laser is, formal education was limited:
50.9% of participants received 0 h of laser education, and only 34.8% reported previous laser practice. Interest
was high (78.2%), and most participants (70.4%) believed both theoretical and practical training are needed.
Overall knowledge was low in 89.7% of respondents, with only 0.6% of participants achieving high overall
knowledge. Knowledge was lowest in operative dentistry (86.6% low) and endodontics (79.4% low), whereas
higher performance was observed in pediatric/orthodontics (16.5% high) and laser safety (17.6% high). Education/
practice level was significantly associated with gender, age, education, workplace, and experience (P < 0.05).
Conclusion: Despite high awareness and strong interest in laser dentistry, Saudi dental trainees and practitioners
demonstrate insufficient formal education, limited practice exposure, and generally low knowledge, supporting
the urgent need for improved curricular integration and structured continuing education.
