Knowledge, behavior and attitudes of dental practitioners towards photodynamic therapy use in dental practice

Abstract

BackgroundThe aim of the present study was to assess knowledge, behavior and attitudes of dental practitioners (DPs) towards photodynamic therapy (PDT) in dental clinical practice. MethodsA cross-sectional study was performed and a 13-item survey questionnaire was given to DPs practicing in 13 different teaching hospitals in Karachi, Pakistan. Questions were aimed at exploring the knowledge of DPs regarding PDT and their attitude towards PDT and perceptions that may influence clinical practices. Chi-square and spearman coefficient were conducted to compare subgroups and correlate factors with the knowledge score of DPs. ResultsA total of 509 questionnaires were completed (response rate=82%). Median age of participants was 34 years and 70% were females. Most DPs demonstrated good knowledge related to PDT, and nearly 77%, 69% and 62% were aware of the mechanism of action and the role of photosensitizers in PDT respectively. It was reported that 74% of the respondents expressed that they are comfortable to know about PDT in detail for their clinical practice. A cumulative 54% disagreed that discussing the option for PDT with their patients was peripheral to their role as clinicians. A striking 82% would like to attend seminars and workshops on PDT. Significant difference was found among senior lecturers and assistant professors for the knowledge items (p <0.05). No statistical correlation was found between the knowledge items score of DPs and their behavior (r=0.18; p=0.762), attitude (r=0.04; p=0.594) and self-rated knowledge (r=0.42; p=0.854). ConclusionDental practitioners showed adequate knowledge regarding PDT and its use in dentistry. However, expertise with regards to handling and training is warranted so that DPs could use PDT in their dental practice.
