Background

Dentists are at greater risk of work-related musculoskeletal disorders (WMSDs) which can be caused by repetitive movements, improper posture and long working hours. If ergonomic principles are applied in the field of dentistry, they help to prevent occupational ergonomic health hazards and provides more comfort to the dentist and patient.

Objective

To obtain information regarding dental ergonomics practice of dentists in Indonesia and its related factors.

Methods

A cross-sectional study was conducted using a purposive sampling method via Google Form to 231 dentists in DKI Jakarta, Indonesia from November to December 2022. The questionnaire consisted of 34 items divided into five sections; socio-demographic, job characteristics, knowledge of dental ergonomics, attitude towards dental ergonomics and the practice of dentists regarding dental ergonomics. Bivariate analysis was conducted using Pearson Chi-square Test.

Result

76.2% dentists have poor dental ergonomics practice. There is a significant relationship (p-value < 0.05) between the practice of dental ergonomics and age group, years of practical experience and level of knowledge.

Conclusion

Most Indonesian dentists (76.2%) still lack of dental ergonomics practice. Age, duration of work experience and ergonomic dental practice knowledge are significantly correlated.

Objectives

Gingivitis is a common inflammatory lesion caused by the build-up of oral biofilm and is an essential precursor to periodontitis. For its treatment, oral hygiene habits, such as dental flossing, must be improved, and adjunctive materials, such as hyaluronic acid, may be used to reduce plaque formation and gingival inflammation. This study aimed to assess the effects of 0.2% hyaluronic acid gel-impregnated dental floss on the clinical periodontal markers of patients with gingivitis.

Material and Methods

This clinical study adopted a split-mouth, randomised controlled trial design. After clinical data were assessed at baseline, and supragingival scaling was performed, bilateral gingivitis regions were randomly allocated to either the hyaluronic acid gel-impregnated floss group or just the floss group using a computer-generated randomisation table. Clinical parameters were recorded at 1, 2 and 4 weeks after treatment.

Results

Over the 4-week trial period, all patients showed significant improvements in all clinical periodontal markers. The 1-week plaque index, 4-week gingival index and 4-week papillary bleeding index were significantly lower in the test group than in the control group (p < 0.05).

Conclusions

The use of hyaluronic acid-impregnated dental floss has resulted in more significant improvements in clinical periodontal parameters compared to dental floss alone. For ease of use, ready-made products with this innovative formulation may be produced.

Objectives

This study aimed to evaluate the concentrations of total fluoride (TF), total soluble fluoride (TSF) and ionic fluoride (IF) in various toothpaste brands marketed in Saudi Arabia and compare them with the labelled values.

Methods

Twenty toothpaste brands were randomly selected from supermarkets and hypermarkets in Riyadh, Saudi Arabia. For each brand, two samples from different production batches were purchased and labelled as sample 1 and sample 2. TF and TSF were determined chemically, while IF was measured with fluoride electrodes. The measured fluoride concentrations were compared with the labelled values and the recommended 1000–1500 ppm range for effective caries prevention.

Results

In total, 40 toothpaste samples were analysed (20 from each of two batches). For TF, six toothpastes in sample 1 exceeded the standard limit of 1500 ppm, with a range of 2102–2462 ppm, while nine in sample 2 surpassed the limit, ranging from 1538 to 1846 ppm. Conversely, eight toothpastes in sample 1 and two in sample 2 were below the minimum recommended level of 1000 ppm, with ranges of 308–923 ppm and 615–923 ppm, respectively. The TSF ranged from 924 to 2157 ppm in sample 1 and 923–2154 ppm in sample 2. The IF varied from 615 to 2462 ppm in sample 1 and 308–2154 ppm in sample 2.

Conclusions

Most toothpaste brands had fluoride levels within the recommended concentration range. However, a significant number exhibited fluoride levels either below the minimum effective dose or exceeding the maximum recommended limit. Fluoride variance in toothpaste demands awareness for dentists and public health to guide optimal caries prevention.

Introduction

To examine the content of Turkish videos on YouTube about tooth brushing and to evaluate their usefulness in providing information to the public.

Methods

Two keywords were determined using the website Google Trends. For each keyword, the top 100 most watched videos were determined according to the searches made on YouTube and a total of 200 videos were examined. According to the inclusion and exclusion criteria, 99 videos were included in the study. The URL address of each video included, the number of views, the number of likes, the number of dislikes, the duration of the video, the time elapsed since the upload date (days) and whether the videos was narrated by a dentist, commercial institution or individual user was recorded. In addition, the interaction index and viewing rates of the videos were calculated. The contents of the videos included were evaluated by a specialist dentist.

Results

Based on the evaluation of the information content of the videos, 54.5% of them contained minimal information, 38.4% poor information, 5.1% good information and 2% excellent information. The two videos containing excellent information include 10 of the 12 topics evaluated and both videos are narrated by a dentist.

Conclusion

Turkish videos about tooth brushing on YouTube are insufficient in terms of content and accurate information. For this reason, individuals should be directed to professional sources in order to receive accurate and up-to-date information, and dentists should share videos containing sufficient content and quality information on this platform.

Aims

This study aims to report on the development and validation of the Attitude of Nursing staff towards Oral healthcare for Care-dependent Older adults (ANOCO) questionnaire.

Methods

The development of the ANOCO questionnaire was performed in three stages between 2008 and 2019. In a first stage, domains related to oral healthcare attitudes were identified. Next, relevant statements per domain were formulated by a Delphi panel in two rounds, resulting in a questionnaire with 32 statements. In a final phase, this questionnaire was subjected to psychometric analysis, including an evaluation of the construct validity, an internal consistency analysis (Cronbachs alpha) and a principal component analysis.

Results

The questionnaire could significantly distinguish between known groups (dentists, nurses' aides, nursing students and nurses). Regarding internal consistency, Cronbach's alpha was 0.863 in the first sample (n = 361) and 0.843 in the second sample (n = 1051). Based on principal component analysis, 22 statements were retained. Four components with an eigenvalue of more than 1 explained 45% of the total variance.

Conclusion

The ANOCO-22 questionnaire consists of 22 statements and is a valid tool to assess the changes or differences in the attitude of nursing staff towards oral healthcare for care-dependent older adults.

Objectives

The purpose of this study was to assess the selection and sequence of dental hygiene instruments taught during dental hygiene pre-clinical education in the United States.

Methods

Exempt status was received from the University of New Mexico's IRB (ID 21-336). A survey was developed with questions to be answered involving decisions for clinical teaching and sequencing on various assessment and implementation instruments during pre-clinic education. The instrument was 11 questions with multiple choice, ranking and short answer. A survey link was included through email invitation and successfully sent to 301 accredited dental hygiene programme directors in the United States. Results were collected and analysed through descriptive statistics.

Results

Forty-three of the invited participants completed the survey, a 14% response rate. Almost half (n = 24) of the participants chose to teach the periodontal probe first and 19 chose the explorer. Twenty-five participants selected they teach the sickle scalers first, 14 teach the universal curette scalers first and 4 teach the Gracey curette scalers first. All participants teach electronically powered scalers with 33 teaching after hand instrumentation and 8 before.

Conclusions

Results from this study emphasise that educators teach clinical instrumentation from professional opinion, but no attestation specifically suggests the use of evidence-based pedagogical standards for clinical teaching. Dental hygiene programmes could benefit from further research on pre-clinic instrument selection and sequencing as a way of standardised clinical teaching. These clinical implications could advance the science for standardised teaching of clinical instrumentation and sequencing in dental hygiene education.

Objectives

This longitudinal text-mining study examines dental hygiene students' perceptions of dental hygienists and dentists at three different points in time during their training course. The null hypothesis of the study was that there would be no change in the dental hygiene students' perceptions of the dental hygienists and dentists over the course of 3 years.

Materials and Methods

First-year dental hygiene students participated in this study beginning with the academic year 2020. The questionnaires were conducted in 2020, 2021, and 2022. Participants were asked to write their perceptions of dental hygienists and dentists on the questionnaire sheets, and a quantitative text-mining analysis was performed.

Results

Initially, 59 female students were assessed for enrollment in this study, and the overall participation rate was 88.1%. The first-year students' perceptions of dental hygienists were “assist” and “beside” the dentist based on the co-occurrence group, while in the second-year, “cleaning” and “tooth” emerged in this group, and a new group of “cordinal-listen-story” materialised. In the third year, these groups merged into one group centered on “kind.” In the perceptions of dentists, the word “fear” was the most frequent before clinical training, while the frequency of the world “kind” increased after clinical training. The word “treat” was ranked third in the second year of curriculum and then first in the final year.

Conclusions

The null hypothesis was rejected. It can be concluded that if interactions between dental hygiene and dental students are systematically incorporated from early undergraduate education, clinical practice will be more meaningful and lead to stronger intraprofessional collaboration in future clinical practice.

Objectives

To compare the efficacy of chlorhexidine (CHX) and amine fluoride (AF) toothpastes on oral flora in fixed orthodontic treatment patients.

Methods

Thirteen patients were given toothpaste containing AF, and 12 patients were given toothpaste containing CHX. Microbial and periodontal records were taken before, 1 week, and 5 weeks after the bonding procedure. Gingival index (GI), plaque index (PI), and bleeding on probing (BOP) values were recorded by the same expert calibrated before the study. Biofilm samples were taken, and then colony counts of the samples were evaluated. Whether the variable values obtained in the groups at the time of measurement were different was examined by Nonparametric Analysis of Longitudinal Data in Factorial Experiments—Nonparametric Tests for the F1_LD_F1 design for longitudinal data.

Results

Gender distribution was similar in the study groups (χ² = 1.944; p = 0.163). The mean age of the patients did not differ in the groups (t = 0.502; p = 0.620). In general, the variable values analysed within the scope of the study did not show significant differences between groups and time (p > 0.05). When the pairwise interactions were analysed, it was found that there was a significant difference only for PI values (F = 3.411; p = 0.035).

Conclusions

While there were no significant differences observed in BOP, GI, and S. mutans levels and changes in IgA and IgE values between toothpastes containing CHX and AF, the PI index of CHX-containing toothpastes exhibited a notably lower level. Both AF- and CHX-containing toothpastes can be used for managing biofilm, controlling bacteria, and minimising gingivitis in subjects undergoing fixed orthodontic treatment.
