Root Canal Treatment for Older Adults: New Zealand Dentists’ Experiences and Approach to Practice

BACKGROUND: This study investigated the experiences and approach to practice of New Zealand (NZ) general dental practitioners (GDP) providing root canal treatment (RCT) for older adults. METHODS: A national online survey collected data from GDPs managing older adults including their approaches to pulpal diagnosis and RCT techniques. Questions also explored informed consent, specialist referrals, confidence, treatment outcomes and engagement with continuing education. Data were analysed descriptively and bivariate analysis of categorical variables used Chi-square and Fisher's exact tests. RESULTS: A total of 382 GDPs participated (response rate 23.6%). RCT for older adults was common, and most dentists felt confident and incorporated contemporary techniques, although they were less comfortable managing polypharmacy or complex medical conditions. Verbal consent was usual. Almost three-quarters had updated their endodontic knowledge and skills within the previous 2 years through continuing professional development. Around two-thirds found diagnosis challenging; however, RCT was viewed as successful. Females were less confident, and a proportion did not treat molars. CONCLUSION: Older adults commonly require RCT, and enhancing GDPs' knowledge and skills to manage patients with a range of medical conditions is important. Written consent is advised for RCT when patient or tooth factors are complex, or where patients' capacity may be impaired.
