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.

Trial registration: ClinicalTrials.gov identifier: NCT06307041.

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.

Objective: This pilot study aimed to explore knowledge, attitudes and confidence levels of Obstructive Sleep Apnoea (OSA) before and after case-based education among dental hygiene students. Moreover, to give an international perspective, this study included students from the US and Scandinavia.

Methods: A longitudinal multicentre study assessed dental hygiene students' OSA knowledge, attitudes and confidence through a case-based education model. Students from six dental hygiene programmes in the US, Norway and Sweden participated from 2021 to 2022. The intervention group (N = 89) received preview material, live synchronous OSA lecture, case-based screening of fictitious patients and clinical practice using the STOP-Bang screening tool. Controls (N = 70) followed the standard curriculum. The Obstructive Sleep Apnoea Knowledge and Attitudes (OSAKA) questionnaire, comprising 18 knowledge and five attitude/confidence questions, was used. Reliability was assessed and nonparametric tests determined OSAKA knowledge score differences among the baseline, 6 months and 12 months intervals.

Results: The intervention increased OSA knowledge with the largest increase in proportions of correct responses occurring between the baseline and 6 months and all single items showing a higher proportion of correct answers at 12 months compared to the baseline. Students' attitudes regarding the importance of OSAKA and confidence in managing patients increased from the baseline to both 6 months and 12 months.

Conclusion: The case based educational intervention increased OSA knowledge and improved attitudes and confidence among dental hygiene students. The results also determined that the OSAKA questionnaire can be used in a setting with dental hygiene students to provide an overview of their knowledge, attitudes and confidence toward OSA. Current sleep medicine education in dental hygiene programmes is limited, suggesting the need for enhanced and sustained educational interventions to address this knowledge gap.

Objectives: This registry-based study aimed to describe cross-sectional dental and demographic data with focus on diagnosis and treatment of periodontal disease. A second aim was to analyse the extent and content of performed periodontal treatment in patients with varying degrees of periodontitis and if treatment was provided on equal terms. An additional aim was to identify if possible differences in treatments were related to type of dental insurance system.

Methods: A study population, 225,913 individuals ≥ 20 years living in the Region of Västra Götaland, was identified by the Swedish Quality Registry for Caries and Periodontal Diseases (SKaPa). Registry data were retrieved for the period 2010-2012. Logistic regression models were used to predict the probability of receiving periodontal interventions and access to fixed annual fees.

Results: Among the study population, 17% had periodontal disease (≥ 4 teeth with periodontal pockets ≥ 4 mm) and constituted the final study sample. The probability of periodontal intervention increased with severity of periodontitis, in moderate (OR = 2.3) and severe cases (OR = 5.2) compared to the group with minor disease (p < 0.001). Severe periodontitis was associated with male gender, increasing age and smoking. About 30% of the individuals remained untreated over the 3-year period. Individuals with fee-for-service were more likely to receive periodontal intervention than individuals with fixed annual fees (OR = 1.7; p < 0.001).

Conclusion: Severe periodontitis and being in the fee-for-service system were associated with more periodontal interventions. However, one-third of the study subjects remained untreated. These findings indicate the need for improved care on equal terms for patients with periodontal disease.

Objective: Bacterial biofilm control around dental implants is critical for the health of the peri-implant soft tissue and longevity of dental implants. The patient's role in regular biofilm removal around dental implants is just as important as that of the dental hygienist. The purpose of this study is to identify the relationship between at-home dental implant care and patients' perceptions of peri-implant soft tissue health.

Methods: A 15-item paper survey was distributed to adult patients undergoing professional dental hygiene maintenance at a specialty dental practice within a 3-month period and had at least one dental implant. Survey items included participant demographics, patient-reported adjunctive aids for dental implants and patient perceptions of dental implant oral hygiene practices and peri-implant soft tissue health.

Results: There was a statistical difference between time spent cleaning dental implants and peri-implant soft tissue health. An association was found between patients who reported spending more time cleaning their dental implants and less bleeding (p = 0.046/54%), gingival inflammation (p = 0.026/58%) and gingival tissue redness (p = 0.036/53%). Additionally, patients who more frequently underwent professional dental hygiene maintenance perceived less gingival inflammation (p = 0.001/66%).

Conclusion: To promote peri-implant soft tissue health and reduce oral biological complications, best practice guidelines should be implemented, including optimal at-home dental implant care and regular professional dental hygiene maintenance.
