Abstract

A successful complete denture treatment can be achieved when the patients are motivated and aware of appropriate denture wear and oral hygiene maintenance. General and oral health could improve through quality of life. Hence, the purpose of this study was to evaluate denture hygiene knowledge attitude and practice towards patients education among dental interns and practitioners. A total of 190 participants were included in the study. A cross-sectional survey was conducted among interns and practitioners. The questionnaire was divided into 3 parts based on knowledge, attitude and practice and the collected data were analysed using SPSS software. Chi square test was performed to determine the statistical significance. In this present study, majority of participants (93.7%) were aware of plaque accumulation in dentures and about 50.5% of the participants agreed that explaining denture hygiene instructions to patients was time consuming. 45.3% of the participants recommended denture cleansing tooth brush and 42.6% of the participants recommended regular toothbrush for denture cleansing. Association between level of education and knowledge of the respondents about removal of denture adhesive on a daily basis showed positive association (p<0.05). Association between level of education and the medium by which instructions were given to patients shows positive significance (p value <0.05). Positive association was present between place of practice and explaining denture hygiene instructions to patients is very time consuming (p value <0.05). Association between gender and recall program for complete denture patients is not important as denture teeth are artificial teeth, showed significance (p value <0.05). Association between gender and methods which respondents recommend for denture cleansing to patients was statistically not significant (p value > 0.05). Knowledge, attitude and practice among interns and practitioners had limited knowledge on denture cleansers and the importance of denture hygiene practice.

Introduction

Recent decades, there has been an increase in the number of elderly patients and the need of dentures to replace missing teeth has also increased [1-3]. Providing conventional dentures (complete dentures) is a usual process to restore the anatomical structures, form, chewing function and esthetics [4]. Effectual maintenance of oral hygiene plays a vital role to improve the quality of life and success of prosthodontic treatment [5].

The aggregation of stains, soft and hard debris on removable dentures may be an unpleasant consequence on the patient’s oral health status and many denture wearers find it very difficult to clean the denture [6]. Few studies indicate that many patients fail to keep their dentures clean and continue to use the dirty dentures [7, 8]. Inappropriate cleaned dentures which may result in halitosis, poor esthetics and gum irritation like denture-induced stomatitis [9]. In addition, habits such as wearing of complete dentures at night have proved to cause denture related stomatitis [10-14]. Denture stomatitis is one of the most common fungal infections that are seen in patients who wear removable dentures [15]. Several studies conducted on denture stomatitis, nearly 15% to 70% of denture wearers affected different populations worldwide [16-18].

The micro-porous surfaces on acrylic removable dentures provide a wide span of different environments in order to carry microorganisms which may harm the health of a denture patient. [8, 19, 20]. There are generally two approaches recommended to the patient's Dentures that can be cleansed mechanically, chemically or through a combination of these [21-23]. Denture care is handled easily, effective for removal of organic/inorganic deposits and stains. Thus, the brushing is the most common way to clean the removable dentures. However, the use of toothbrushes is effective and has better outcomes [20]. To have effective and regular denture hygiene, it is important for dentists to provide proper denture hygiene instructions to the patients [24]. Although, Complete denture wearers pay less attention towards the oral hygiene in comparison to the dentate [23]. Dentists should encourage, motivate and guide the patients through providing them and ways to control plaque which maintain good oral hygiene [25, 26].

Studies have shown that most denture wearers have poor oral hygiene, poor denture cleanliness which may facilitate the accumulation of attribute biofilm [7, 8, 17, 27]. Most of the researchers have concentrated on the denture wearers knowledge and attitude towards denture cleansing [5, 28, 29]. The study focused more on the knowledge, attitude and practice of the dentists towards patient education at the time of denture delivery and there are very few studies only available. Previously our team has conducted numerous original studies [30-44] over the past 5 years. The plan for this study stemmed from the contemporary interest in our community.


Materials and Methods

The survey was conducted among dental interns and practitioners using a self administered questionnaire. We modified and reviewed a questionnaire conducted previously published by Suresh V et al., [26]. A total of 190 participants have been randomly enrolled. An online questionnaire which was distributed electronically using a link generated by google forms. Demogrpahic information was obtained from the participants such as gender, level of education,year of practice,place of work. The questionnaire consisted of 17 questions closed ended questions which were divided into 3 parts based on knowledge,attitude and practice. The first part contains 5 questions related to knowledge associated with denture hygiene maintenance. Second part contains 5 questions related to the attitude towards denture hygiene instructions during delivery of the dentures to the patients there were not many literatures available. Third part contains 7 questions related to the denture hygiene practice recommended. Informed consent was obtained from all participants. The participants' information was kept anonymous and also confidential. The collected data were tabulated and imported into the IBM SPSS Statistics for Windows, Version 20.0. Chicago: SPSS Inc program to extract the means and percentages. Chi‑square test was performed for nonparametric study and was enrolled to determine the statistical difference between the two variables where p value < 0.05 is considered statistically significant with a confidence interval of 95%. Pie charts and bar charts were used for pictorial representation of the result of the present study.


Results and Discussion

About 83.7% reported that they will recall patients for review and the rest 16.3% don't recall patients for review (Figure 20). About 35.8% of participants recommend cleansing the denture with water followed by alkaline per-oxide tablet 23.7%, bruising with soap water 21.6% and diluted hypochlorite 18.6% (Figure 21). In the current study, Interns are more likely to concur than specialists and practitioners that denture need not be removed completely and reapplied on a daily basis (p < 0.05) (Figure 22). Interns are more probable to instruct the verbal and practical demo than specialists and practitioners (p < 0.05) (Figure 23). Hence, this association was found to be statistically significant. There is significant association between the place of practice and denture hygiene instructions to denture wearers (p <0.05) (Figure 24). Furthermore, females were more probable to concur than males that a recall program for complete denture patients has no importance due to denture teeth (p < 0.05). Therefore, which shows statistically significant (Figure 25). Based on the results, females were more likely to recommend cleaning the denture by brushing with water (p > 0.05) (Figure 26).

Denture hygiene is a familiar problem in elderly patients worldwide and confronted by the prosthotic dentists [45]. Especially the elderly patients, who are not able to maintain good denture hygiene by reason of mental and physical handicap [26, 46]. The knowledge among the dentist on denture hygiene maintenance is very important. Dentists should have adequate knowledge to train and instruct the patients on the significance of denture hygiene. Recall the patient on a regular interval to ensure if denture hygiene is maintained [25].

However, these findings were disparity with previous study was done by Razan Fahad AlEidan et al., [25] In the current study, most of the participants reported that educating patients regarding the impact of denture hygiene on systemic health is not important and 39.5% of participants believe that denture adhesives need not be cleaned completely and reapplied daily on a daily basis. It was found from the study that most of the practitioners recommended cleansing of dentures twice daily. These findings were not in agreement with Razan Fahad AlEidan et al.,[25] In the present study, nearly 87.9% of participants recommended that they advise the patients on denture cleansing methods. In a previous study, which was conducted with a variance study done by Amand Peracini et al., and reported that 51.89% of patients did not get proper advice on denture cleansing [47]. Similar study was seen in previous literature, proper instructions on denture cleansing was obtained only for 40 patients out of 234 patients [8]. We observed that the most common method to use for cleansing the dentures using brush with water by 35.8%. Majority of the participants reported verbal and practical demos (42.1%) for providing denture instructions to the patients. This study is contradictory with previous study conducted by Vinay Suresan et al., [26] In the present study, most of the practitioners recommend the use of denture cleansing brush (45.3%) followed by regular toothbrush (42.6%) for cleansing the dentures. Majority of the participants recommend removing the dentures at night. A periodic denture check up recommended by most of the interns and practitioners. These results were concurrent with Razan Fahad AlEidan et al.,[25].

The limitations of this study, it is limited to a smaller number of participants. In future, especially for the speciality, age among dentists should be carried out in a large population.


Conclusion

Based on the results of this study, it can be concluded that interns, specialists and practitioners had limited knowledge in denture hygiene, denture cleansing methods and materials. It is essential to spread awareness among dentists to educate their patients about correct methods and practices to clean and maintain their dentures. Educators pay more attention to reinforce the skill of their graduates in order to improve dental care services. Dental professionals should update themselves about new materials available in the market to create denture hygiene among patients such that the treatment will be successful in elderly patients. Oral hygiene and general health will be improved towards quality of life.
