An internet-mediated investigation into the reported clinical use of rubber dam isolation by GDPs in the UK - part 1: factors influencing rubber dam use

Aims: To investigate the reported use of rubber dam isolation by UK general dental practitioners, utilising an internet-mediated (SurveyMonkeyTM) questionnaire reporting the demographic profile of respondents and the attitudes and factors influencing rubber dam use. Methods: A piloted questionnaire was distributed to a random sample of GDPs in a private FacebookTM group investigating respondent demographics, clinical applications, attitudes towards and factors influencing dam use. The data was analysed using descriptive statistics along with Chi-square and Mann-Whitney U tests. Results: The response rate was 61% with 403 valid completed questionnaires. Of these, 218 (54%) were female and 185 (46%) were male with an age range of 23-72 years. Most, 248 (62%) worked in mixed-practices. The majority agreed rubber dam aids placement of posterior restorations 311 (78%), provides clearer access 308 (76%), enables a higher clinical standard 355 (89%) and increases treatment longevity 257 (65%). Most agreed proper isolation for root canal/operative procedures cannot be achieved without rubber dam use 329 (82%). Respondents disagreed with the statements root canal therapy completed without rubber dam isolation is as successful as those completed using rubber dam 338 (85%), rubber dam is difficult to apply 292 (73%) and is disliked by patients 257 (64%). Respondents agreed rubber dam use is influenced by clinical setting 259 (64%), procedure 390 (97%), choice of material being placed 382 (95%) and ease of application 337 (84%). Furthermore, 218 (54%) of the respondents expressed an interest in further training in rubber dam use. Conclusions: This study provides greater insight into the attitudes and factors influencing rubber dam use, whilst demonstrating an interest in further training.
