ABSTRACT

Aim and objective: To assess the attitude, practice, and barriers toward the use of rubber dam during endodontic and operative procedures among dentists in Jazan, Saudi Arabia.

Materials and methods: An online descriptive cross-sectional questionnaire survey was conducted among the dentists practicing in the Jazan region, Saudi Arabia. A total of 259 dentists participated in this study. Convenience sampling was used due to the limitation in the study duration and COVID-19 pandemic. The data collection were done online using a questionnaire designed at www.Kwiksurveys.com. The association between the independent variables and the responses to the questions was tested using the Chi-square test. Statistical significance was determined at α = 0.05.

Results: About 75% of participants mentioned that rubber dam was available in their clinic; however, only 71% had used it for their patients. Regarding the barriers that prevent the usage of rubber dam, 68% cited as financial reasons, 25% mentioned that they are not fully aware of how to use it, while 6% said that rubber dam was not available. A statistically significant association was found between training on rubber dam use, the working sector professional classification and experience, and using rubber dam for patients in the clinic. No statistically significant association was observed between rubber dam use and gender and place of education.

Conclusion: The participants had a favorable attitude toward rubber dam use. The training, operator experience, and workplace are favorably associated with rubber dam use. Increased cost, insufficient training, and non-availability of rubber dam were reported as the greatest barriers to regular usage.

Clinical significance: Most of the barriers reported for the non-usage of rubber dam are myths that have been propagated over time. The benefits of rubber dam use significantly outweigh the costs incurred.

Keywords: Dentists, Endodontics, Online survey, Questionnaire, Rubber dam..

INTRODUCTION

Operative and endodontic procedures are performed to treat tooth damage caused by dental caries or trauma. Tooth isolation during such procedures is paramount to prevent salivary contamination. This enables and ensures proper bonding of the restorative material to the tooth, thereby preventing re-infection and restoration failure. This also protects the patient and the dentists from unnecessary exposure to microorganisms. Poor bonding or secondary caries may compromise the longevity of the restoration.13

The rubber dam, first introduced by Barnum in 1864, is a useful process adjunct during operative and endodontic treatments and still the ideal tool for tooth isolation during dental therapeutic procedures. Rubber dam use has been documented to be essential for effective isolation in endodontic practice. The use of rubber dams during dental treatment procedures is believed to reduce microbial contamination and the potential for patients to swallow or inhale foreign bodies,4 thereby improving the efficiency of root canal treatment and addressing safety concerns.5 The quality assurance guidelines of the American Association of Endodontists state that cleaning, shaping, disinfection, and obturation of all canals are best accomplished using an aseptic technique with dental dam isolation whenever possible. Although rubber dam application is considered mandatory in root canal treatment, its use is not popular among dentists even though its more widespread use has been advocated.6,7 It is well-known that a rubber dam protects patients against the aspiration of instruments, prevents the laceration of soft tissue from rotary or hand instruments, improves accessibility and visibility, aids the retraction of soft tissue to some degree, and impedes cross-infection.3,810 The barriers to rubber dam use routinely by dentists are cited as patient acceptance, cost of rubber dam armamentarium, insufficient training, difficulty in use, the time required for its application, and financial constraints.7 Studies have been reported in other countries on rubber dam use among dentists and dental students.24,1115 There is a lack of knowledge regarding the use of rubber dam in our environment. Given the importance of rubber dam in endodontic treatment, it is imperative to determine the factors affecting its use to enable proper intervention to popularize its use. Hence, this study sought to determine the attitude and practice regarding the use of rubber dam during endodontic and operative procedures among dentists in Jazan, Saudi Arabia.

MATERIALS AND METHODS

An online descriptive cross-sectional questionnaire survey was conducted among the dentists practicing in the Jazan region, Saudi Arabia, to achieve the purpose of this study. Ethical approval was obtained from the Institutional Review Board of Jazan University. All participants filled the informed consent form that contained information about the objectives of this study and their rights to withdraw from the study.

The sample size was calculated based on data on rubber dam usage from a previous study conducted in Saudi Arabia by Al Qarni in 2014.16 A sample size of 254 was required for the present study. The data collection were conducted from October 1, 2020, to December 31, 2020. The Saudi Commission for Health Specialties (SCFHS) database was used to identify the number of licensed dentists in Jazan, Saudi Arabia in September 2020. All licensed dentists practicing in Jazan who responded to the online survey were included in the study.

A total of 259 dentists participated in this study. Convenience sampling was used due to the limitation in the study duration and COVID-19 pandemic. The data collection were done using online questionnaires. A well-constructed questionnaire was developed through www.Kwiksurveys.com. The online survey link was posted on social media and an e-mail to the study participants and the responses were received through online survey submission.

A well-developed and pretested questionnaire was used as a tool for data collection. The questionnaire was tested for validity and reliability. Validity was tested for face validity and good comprehension was reported among respondents. Test–retest reliability was assessed using the intraclass correlation coefficient with a score of 0.87, indicating good reliability. The questionnaire covered two parts; part 1 included demographic information of participants, while part 2 covered variables related to study objectives. There were 14 closed-ended questions in the questionnaire.

The data were analyzed using IBM SPSS v. 24.0 (IBM Statistics, SPSS, Chicago, USA). The data were assessed for normality. The frequency and percentage of the responses were calculated. A chi-square test was employed to test the association between the independent variables and the responses to the questions. A p value <0.05 was considered statistically significant.

RESULTS

The present study was conducted among 259 dentists (males = 143 and females = 116) to assess the attitude and practice regarding the use of rubber dam during operative and endodontic practice using an online survey. The majority of the participants (n = 237, 92%) were general practitioners, and the remaining were specialists. About 52% of participants worked at private clinics, while 48% worked at governmental clinics. More than half of the participants (52%) were from Jazan University, 24% graduated from other universities within Saudi Arabia, while only 12% were from universities outside of Saudi Arabia.

The response rate to the study was 79%. The responses of the participants to the questionnaire are presented in Table 1. When questioned regarding training to use a rubber dam, most participants (95%) had training on using a rubber dam during their study period, and 66% had been trained in using the rubber dam after graduation. Regarding the availability of rubber dams, about 75% of participants mentioned that rubber dam was available in their clinic; however, only 71% had used it for their patients. Only 42% of participants asked patients if they had an allergy to latex before using the rubber dam, and only 28% of patients rejected the use of rubber dam. Most of the participants had a favorable attitude toward the use of rubber dams. The majority of the participants (95%) think that a rubber dam is important during endodontic treatment, and 92% mentioned that the most important use of the rubber dam is in the upper teeth. About 30% said that using the rubber dam is time-consuming. When questioned regarding the barriers that prevent the usage of rubber dam, 68% cited as financial reasons, 25% mentioned that they are not fully aware of how to use it, while 6% said that rubber dam was not available. About 76% of participants used rubber dam immediately after anesthesia, 12% preparing the access cavity, 6% during the preparation of the root canals, while 6% during the obturation when asked about the stage of use. The respondents cited sterile gauze (21%) and sterile cotton (3%) as an alternative to rubber dams.

The association between the independent variables and the responses to the questionnaire was tested using the Chi-square test. A statistically significant association was found between training on rubber dam use and using rubber dam for patients in the clinic (p value < 0.05) (Table 2). Additionally, a statistically significant association was found between rubber dam use and the working sector (p value < 0.05), with a higher percentage (76.6%) of dentists working in the government hospitals using it (Table 3). Also, there was a statistically significant association between rubber dam use and professional classification and experience (p value < 0.05) with specialists (90.6%) and those with a higher experience using rubber dam more often than their counterparts (Table 4). However, no statistically significant association was observed between rubber dam use and gender and place of education.

DISCUSSION

The present study was conducted using an online questionnaire to assess the attitude, perceptions, and barriers toward the use of rubber dams among dentists in the Jazan region, Saudi Arabia.

In our study, we observed a reasonably good usage rate (71%) of rubber dam among the study participants. This finding is in contrast with Unal et al., Peciuliene et al., Slaus and Bottenberg, Ibhawoh and Enabulele, Koshy and Chandler, Csinszka et al., Al Qarni, Sanghvi et al., and Abraham et al. who reported the use of rubber dam ranging from 5 to 57% among general practitioners.2,3,1622 In the present study, no association was found between the place of education and rubber use. The literature has conflicting evidence in this regard. While a few authors found a significant difference in rubber dam use between dentists graduated from different universities,23 yet others found no effect of qualifying school on the frequency of use.20,2427 A significant association was found in our study between the place of work with more practitioners in government sector routinely using rubber dam than those in private clinics. Similar results have been reported by Joynt et al.,28 Koshy and Chandler20 who reported a higher usage among group practices rather than solo practice. Additionally, in the present study, a positive association was observed between training on rubber dam use and using rubber dam for patients in the clinic. Similar findings were reported by Joynt et al.28 We also observed that the years of experience positively affected rubber dam use with more experienced operators having a higher frequency of usage. We found many studies contradicting this finding and reported that the rubber dam use declined with age. There was no effect of gender on rubber dam use in our research which is supported by evidence from previous studies by Marshall and Page and Palmer et al.25,26

The barriers that prevent rubber dam usage in the present study were reported as financial reasons, lack of training and confidence to use, and non-availability of rubber dam in the clinic. Previous studies have also cited various reasons for the low usage of rubber dam by dental practitioners. The most widely quoted reasons include concerns regarding patient acceptance, increased application time, insufficient training and confidence, technique sensitivity, cost of rubber dam armamentarium, and other financial constraints.7 The participants in our research reported that 28% of patients rejected the use of rubber dam, which is also cited as the reason for lack of use by many practitioners in other papers.15,20,23,25,27 However, several other authors have quoted favorable patient reactions toward rubber dam.2931 The operator’s positive attitude, training, competency in rubber dam use, and enhanced experience have known to improve patients’ acceptance.2931

Another reason cited by the participants for non-usage is lack of training. However, most of the participants accepted that they had received training on rubber dam placement in school. Therefore, the limited utilization rate of a rubber dam may be attributed to lack of regular use owing to poor proficiency instead of lack of knowledge or insufficient training.15 The increased cost is customarily quoted as a reason for the infrequent use of the rubber dam.4,20,25,27 Nonetheless, the rubber dam armamentarium has a high shelf-life when appropriately used. Additionally, the benefits of rubber dam use, in terms of infection control, medicolegal, and safety implications, outweigh the costs incurred.15

The recent COVID-19 pandemic outbreak has posed an incredible challenge to the patients and healthcare professionals, particularly dentists. The use of rubber dam isolation in endodontic procedures is essential as the high-speed rotary instruments produce a very high aerosol. This conduct significantly reduces patients’ salivary fluids in the aerosols, thereby depreciating the microorganism suspension in the environment.32,33 Hence, rubber dam use during endodontic and operative procedures cannot be emphasized enough in the present times.

The limitations of the study are due to conducting an online survey the reliability of the opinion expressed by the participant is questionable. As convenience sampling was followed in the study, it may lack external validity.

CONCLUSION

It can be concluded from the present study that the study participants had a favorable attitude toward rubber dam use and deemed it important during endodontic procedures. The training in rubber dam placement, operator experience, and work in the public sector is favorably associated with rubber dam use. Increased cost, insufficient training, and non-availability of rubber dam were reported as the greatest barriers to regular usage.

CLINICAL SIGNIFICANCE

Rubber dam use significantly reduces the chance of salivary contamination, re-infection, and accidental aspiration of dental instruments and materials, thereby improving patient safety, increasing the longevity of the restorations, and protecting the dentists against medicolegal cases. Moreover, it significantly reduces aerosolization of patient’s salivary fluids and contributes to keep dental office teams and patients safe and protected.
