ABSTRACT
Objective: This study aimed to analyze if there is any difference in knowledge between dentists in Surabaya and Jakarta about the 2018 AAP/EFP periodontal disease classification. Method: This analytical observational research utilized an online questionnaire as data collection method. The questionnaire was distributed through PDGI (Indonesian Dental Association) Jakarta and Surabaya WhatsApp groups, with a total of 200 respondents (100 dentists from Jakarta and 100 from Surabaya). Result: In both cities, majority of general dentists have poor knowledge of the 2018 AAP/EFP classification. Dentists who graduated after 2018 tend to have better knowledge of the latest classification system compared to dentists who graduated before 2018. There is a statistical difference between dentists’ knowledge in Jakarta and Surabaya (p < 0.05). Conclusion: Due to the low knowledge, continuous socialization of the 2018 AAP/EFP classification is needed to keep the dentists updated.
