A conflict between dentists knowledge and practice. A Cross-Sectional Study To Assess The Evidence-Based Practice In Periodontology Among Dental Practitioners.
Objectives: The aim of this study is to evaluate variation of the periodontal diagnosis and management of two periodontal cases among restorative dental specialists and general dental practitioners .
Methods: This was an observational analytical cross-sectional study included 3 cohorts ( Periodontists, general dental practitioners and other restorative specialists). Stratified sampling technique by using proportional allocation was used to collect data. Electronic questionnaires were filled by the dentists in face-to-face meeting. The questionnaire contained two clinical cases of periodontitis, followed by a question regarding diagnosis using 2017 periodontal classification and practice related to 4 treatment options and Radiographic judgment about bone loss. There responses were compared using descriptive statistics, chi-square test, binary nad multivariate logistic regression model.
Results: 290 questionnaires were obtained in equal proportion ratio of experience (<5 years and > 5years). Dentists with less than 5 years of experience had significantly higher scores in correct responses compared to more than 5 years of practice experience (p<0.05). Multivariate regression analysis revealed that correct diagnosis in case 1 and 2 were made by periodontists and other specialists (p>0.05) whereas general dentist had less correct diagnosis (p<0.01) for case 1and (p<0.05) for case 2 according to 2017 classification when compared to periodontists. Regarding questions about treatment planning, there was an agreement related to quadrant wise scaling over the other options but significant difference (p<0.05) was found among periodontists when compared to restorative specialists and general dentists in prescribing systemic antibiotics, local antimicrobials and extraction of hopeless teeth in the initial phase.
Conclusions: There is a need of consensus among dental practitioners towards periodontal diagnosis and treatment. Periodontists had significantly more correct responses than general dentists in diagnosis and treatment plan and even with other specialists in treatment plan.
