Introduction: This study highlights the importance of maintaining dental implants, particularly in the context of peri-implantitis. It emphasizes the need for dental hygienists to choose appropriate instruments that will not damage implant surfaces while effectively cleaning them. Materials and Methods: The research involved in vitro tests using 4 ultrasonic inserts for peri-implant mechanical instrumentation on one machined and one etched healing abutment, with a focus on how these instruments affect surface roughness. For each insert, four surface roughness measurements were recorded on each abutment. The data were then analyzed in two separate designs, one for the machined abutments and one for the etched abutments. The significance of the factors was determined by analyzing them using an ANOVA test. Results: The study found significant effects of surface treatment and instrument type on surface roughness parameters. Instrumentation tended to alter the roughness of machined surfaces more than etched ones, with notable differences in performance among the various inserts. Discussion: The results suggest that surface treatment has a more substantial impact on roughness than the choice of instrument. Future studies are encouraged to explore other parameters related to bacterial biofilm retention and the potential release of material from non-metallic inserts. Conclusions: Key findings include that surface treatment significantly influences surface roughness and that specific instruments can either increase or decrease roughness based on the type of surface.

Background: This study determined the validity and applicability of introducing a healthcare-associated infection surveillance system in dental hospitals using the Delphi technique. Methods: The Delphi questionnaire was developed by conducting a systematic literature review and focus group interview involving five dentists and dental hygienists with experience in performing infection control in dental hospitals and three infection control experts. The Delphi survey was administered to 16 experts, including 6 dentists and 5 dental hygienists with experience in infection control, 2 infection control nurses, and 3 infectious disease physicians. Results: The Delphi survey demonstrated a high level of agreement on the necessity of introducing a healthcare-associated infection surveillance system in dental hospitals and the need for dental hospitals to participate in the “Korean National Healthcare-associated Infections Surveillance System” that is currently operated on a national level. However, the level of agreement on the applicability was low given the lack of employees responsible for infection control. Conclusions: Surveillance criteria and a system for process indicators suitable for dental hospitals should be established. We suggest developing infection surveillance indicators and applying trials of the items with a high priority, as assessed in this study, to support dental hospitals’ participation in the “Korean National Healthcare-associated Infections Surveillance System”.

Background/Objectives: With the acceleration of population ageing the need for integrated support in healthcare and caregiving is increasing, and the societal demand for improved service quality is also increasing. This study aims to explore how multidisciplinary professionals perceive the implementation of home-visit oral care (HVOC) within the Integrated Community Care in Older Adults model, in order to inform the design of future integrated oral health programs. Methods: The study participants comprised 16 individuals: eight dental hygienists with experience in HVOC and eight multidisciplinary healthcare providers. Focus group interviews were conducted with these participants, and the data were analysed using Colaizzi’s phenomenological method to derive key themes and categories. Results: The analysis revealed four main thematic categories: (1) cognitive aspects (understanding of geriatric diseases and families); (2) technical aspects (effective communication and competence in oral care); (3) value-based aspects (empathy, patient-centredness, professional pride); (4) multidisciplinary organisational efforts (establishing interprofessional collaboration systems and integrated platforms). Conclusions: HVOC services provided by dental hygienists were found to promote oral health among older adults. To ensure the sustainability and effectiveness of such services, a customised integrated care model based on multidisciplinary collaboration should be established. Full article

Background/Objectives: Despite the bidirectional relationship between diabetes and periodontal disease, dental hygienists’ role in diabetes screening remains underexplored in Japan. Previous studies have not examined the relationship between attitudes and actual screening practices. This study aimed to assess dental hygienists’ attitudes regarding diabetes screening and medical–dental collaboration, examine current practices, and investigate the association between attitudes and practices. Methods: A nationwide cross-sectional survey was conducted among dental hygienists from 1340 dental clinics using stratified random sampling. Participants completed an anonymous questionnaire assessing attitudes (4-point Likert scale) and screening practices (4-point frequency scale). Exploratory factor analysis and multiple regression analysis examined attitude–practice associations. Results: Of 1340 surveys distributed, 95 valid responses were obtained (response rate: 7.2%). Participants showed low implementation rates for lifestyle and physical sign assessment in diabetes (below 35%, except thirst: 68.4%) but moderate-to-high rates for medical history evaluation (44.2–75.8%). Multiple regression analysis revealed that lack of confidence and knowledge in diabetes management was negatively associated with both lifestyle assessment (β = −0.38; 95% CI −0.72 to −0.23) and medical history evaluation (β = −0.55; 95% CI −0.63 to −0.32). Desire to participate in diabetes education was positively associated with medical history evaluation (β = 0.21; 95% CI 0.24 to 4.38). Conclusions: Despite low response rate limiting generalizability, this first nationwide Japanese survey indicates that confidence and knowledge deficits significantly hinder diabetes screening practices. Targeted educational interventions could enhance screening implementation and strengthen medical–dental collaboration, improving early diabetes detection. Full article

Objective: This cross-sectional content analysis aimed to investigate how oil pulling is portrayed on YouTube Shorts, focusing on the types of speakers, claims made, and alignment with scientific evidence. The study further explored how the content may influence viewer perception, health behaviors, and the potential spread of misinformation. Methods: On 28 January 2025, a systematic search of YouTube Shorts was performed using the term “oil pulling” in incognito mode to reduce algorithmic bias. English language videos with at least 1000 views were included through purposive sampling. A total of 47 Shorts met the inclusion criteria. Data were extracted using a structured coding framework that recorded speaker type (e.g., dentist, hygienist, influencer), engagement metrics, stated benefits, oil type and regimen, the use of disclaimers or citations, and stance toward oil pulling rated on a 5-point Likert scale. Speaker background and nationality were determined through publicly available channel descriptions or linked websites, with user identities anonymized and ethical approval deemed unnecessary due to the use of publicly available content. In total, 47 videos met the inclusion criteria. Results: Of the 47 YouTube Shorts that met the inclusion criteria, most were posted by influencers rather than dental professionals. These videos predominantly encouraged oil pulling, often recommending coconut oil for 10–15 min daily and citing benefits such as reduced halitosis and improved gum health. However, a smaller subset advanced more extreme claims, including reversing cavities and remineralizing enamel. Notably, US-licensed dentists and dental hygienists tended to discourage or express skepticism toward oil pulling, assigning lower Likert scores (1 or 2) to influencers and alternative health practitioners (often 4 or 5). Conclusions: YouTube Shorts largely promote oil pulling through anecdotal and testimonial-driven content, often diverging from evidence-based dental recommendations. The findings reveal a disconnect between professional dental guidance and popular social media narratives. While some benefits like halitosis reduction may have limited support, exaggerated or misleading claims may result in improper oral hygiene practices. Greater engagement from dental professionals and improved health communication strategies are needed to counteract misinformation and reinforce oil pulling’s role, if any, as an adjunct—not a replacement—for standard oral care. Future studies should explore viewer interpretation, behavioral influence, and cross-platform content patterns to better understand the impact of short-form health videos. Full article

Background/Objectives: Communication skills are a core professional competency for dental hygienists. Accordingly, it is vital to develop a systematic scale that can objectively predict the relationship among communication skills and job satisfaction and various psychosocial factors. This study aimed to develop and validate the Patient-Centered Communication Competency Scale (PCCS) in dental hygienists for dental health service. Methods: Initial items were generated through a literature review, expert content validity assessment, and a preliminary survey. An online survey was conducted with 400 dental hygienists working in dental clinics and hospitals. Construct validity was examined using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA), while reliability was assessed with Cronbach’s alpha. Results: The preliminary 38-item scale was refined through five rounds of EFA, resulting in an 11-item scale with three subscales: Assertiveness, Empathy, and Respect. CFA results indicated good model fit (χ²/df = 1.749, RMR = 0.027, RMSEA = 0.061, GFI = 0.941, NFI = 0.911, IFI = 0.960, CFI = 0.959, TLI = 0.949), demonstrating strong convergent and discriminant validity. The PCCS also demonstrated high internal consistency (Cronbach’s alpha = 0.862) and criterion validity, confirmed by its positive correlation with self-efficacy and job satisfaction. Conclusions: The proposed PCCS is a valid and reliable tool for assessing and improving dental hygienists’ communication skills, with potential applications in training programs and communication competency research in dental settings.

Background: Oral diseases represent a constant burden for health care and socio-economic systems as they are correlated to other non-communicable diseases. The aim of the proposed intervention is to test the effect of daily tooth brushing and oral health education on the oral health status of kindergarten children. Methods: The protocol will be conducted based on a previous epidemiological survey and conducted over 24 months; it has been developed on different levels. Dental hygienists will receive specific training to deliver oral health promotion to children and nursery educators. Training will focus on tailoring key messages to the specific age at visit; this will be outlined in the care pathway and offer practical preparation for delivering interventions and a toothpaste/toothbrush scheme. It will also, involving involve offering free daily tooth brushing to every 4–6-year-old child attending nursery. Data will be collected in four kindergartens in the capital or metropolitan areas, two kindergartens each in two large cities, and one kindergarten each in four villages from different geographic areas. Procedures used to assess the outcomes of each activity will be tailored to specific outcomes. Daily tooth-brushing activities will be monitored using qualitative research. A cost analysis including the distribution of necessary materials and correct delivery of products that shows price trends and percentage differences over the time span as well as consumer price index evaluation for the given time span will be conducted. Clinical outcomes will be evaluated using the caries incidence rate; this will be calculated for each tooth as the unit of analysis and evaluated using a multi-step approach. Discussion: Downstream oral health prevention interventions, like clinical prevention and oral health promotion, aim to enhance children’s quality of life. The program’s goal is to progress towards upstream interventions for a more significant impact. Full article

On 24 February 2024, Italian physicians, dentists and oral care specialists, students, nurses, psychologists, dental hygienists, and other professionals met (live or online) to discuss controversial issues about medication-related osteonecrosis of the jaw (MRONJ). One section hosted international experts who gave lectures about MRONJ experiences in North America, Europe, and Italy. A second section summarized the principal points of an Italian MRONJ position paper published in February 2024 by experts from the Italian Societies of Oral Pathology and Medicine (SIPMO) and Maxillofacial Surgery (SICMF). The following section collates expert opinions about open issues and required fields of research: different definitions of MRONJ and impact on staging; the assessment of individual MRONJ risk before the start of antiresorptive therapy; surgery and implantology in patients at risk for MRONJ; cancer patients without metastases and prevention of cancer-treatment-induced bone Loss (CTIBL); the role of dental hygiene professionals; combined (medical and surgical) and surgical therapy for MRONJ in-patients and out-patients; and legal aspects and claims related to MRONJ diagnosis and treatment. Scientific contributions from hospitals and universities all over Italy were presented in specific sessions (epidemiology; case series; special case reports; prevention experiences; MRONJ treatment). Conclusions: the conference confirmed the importance of the adequate imaging study of bone in the diagnosis and staging of MRONJ cases, the role of surgery in MRONJ treatment, and the value of oral hygiene in the MRONJ prevention.

Objectives: A thorough knowledge of tooth morphology, encompassing the detailed structural complexities, is essential for the practice of dental hygienists in all aspects of their profession. The aim of this study was to assess the efficacy of two instructional approaches in tooth morphology education, by analyzing the performance of dental hygienist students trained with human extracted teeth compared to those educated with plastic teeth models. Methods: This study included two cohorts of undergraduate dental hygienist students: a control group (n = 27) trained using human teeth, and an experimental group (n = 34) trained using plastic teeth models. Each group underwent two consecutive practical exams where they identified all 32 permanent teeth and 8 deciduous molars. Initially, students were tested on the training material that they were assigned (either extracted human teeth or plastic teeth), and, subsequently, they were tested using the alternative material. Both the number and patterns of identification errors were recorded and analyzed. Paired t-tests were used to compare error rates between real and plastic teeth for students trained on either plastic or real teeth, unpaired t-tests were conducted to assess differences in performance between students trained on plastic versus real teeth when tested on both tooth types, and Fisher’s exact tests were employed to examine variations in error proportions across maxillary and mandibular tooth categories. Results: The control group recorded a mean of 6.41 errors per student (total of 173 errors), with three students (11.1%) failing by committing over 12 errors. Their performance improved to a mean of 5.44 errors (total of 147 errors) when tested on plastic teeth, although the improvement was not statistically significant (p = 0.20). Conversely, the experimental group demonstrated high accuracy on plastic teeth, with 19 out of 34 students (55.9%) achieving perfect scores and a total of only 50 errors (mean, 1.47). Their performance, however, declined when tested on real teeth, escalating to a total of 354 errors, with 32 students (94.12%) making more errors on real teeth than on plastic, resulting in a significant increase in errors to an average of 10.41 per student (p < 0.001). Conclusions: This study demonstrates that students perform best when tested on the materials that they initially were trained with, showing that real teeth provide better educational outcomes than plastic models. This advantage underscores the importance of using natural teeth when learning dental anatomy. Full article

Background: Orthodontic appliances increase biofilm accumulation by expanding plaque retention sites. Enamel demineralization and periodontal inflammation are considered to be the most prevalent consequences of biofilm formation in orthodontic patients, with reported prevalence rates of up to 50%. To date, there are different procedures and indications that have been used for the treatment of these conditions. Therefore, professionals may use different technologies and protocols to control bacterial biofilm. The aim of this study was to investigate the protocols and technologies used by Italian dental professionals to maintain good oral health in orthodontic patients before, during and after treatment. Methods: A total of 155 dental professionals, dentists, dental hygienist students and dental hygienists, attending the Italian Academy of Advanced Technologies in Oral Hygiene Sciences (A.T.A.S.I.O.) congress, completed a questionnaire to identify prevention technologies and protocols before, during and after orthodontic treatment. Results: The results show equivalent responses between dentists and dental hygienists, with most dental hygienists more likely to personalize treatment. Remineralization technologies and protocols are selected based on patient characteristics. During professional oral hygiene sessions, the most commonly used technologies before, during and after therapy are ultrasonic scaler and airflow with powders. Mouthwashes and toothpastes are customized and shared with the patient, with remineralizing technologies predominant in toothpastes. After treatment, aesthetics is evaluated and the whitening protocol is selected based on the patient’s characteristics. Conclusions: There is not a specific prevention program associated with each orthodontic therapy in the literature, so it is necessary to tailor the treatment to best manage the risks of orthodontic therapy and maintain healthy tissues.

Background: Drug-induced gingival enlargement is a commonly documented adverse effect in patients administered with calcium antagonist medications. Nifedipine is the medicine most frequently linked to instances of gingival enlargement; nevertheless, amlodipine, likewise a calcium antagonist, can elicit this adverse effect. This case report aims to detail a case of amlodipine-induced gingival hyperplasia, emphasizing the significance of a multidisciplinary approach and outlining its therapy across various surgical phases. Methods: A 48-year-old hypertensive patient using amlodipine therapy presents with aberrant gingival tissue growth in the upper arch. Intraoral examination reveals localized inflammation and tissue enlargement in the papillae areas of the upper arch gingiva, leading to partial covering of the dental crowns. The patient experienced painful sensations and episodes of spontaneous bleeding in the enlarged gingival tissue. Following an initial professional dental hygiene treatment, which included root planning in the upper quadrants, and in consultation with the referring cardiologist, it was determined to discontinue amlodipine and initiate a replacement therapy with olmesartan medoxomil. Fifteen days following the cessation of amlodipine, surgical excision of the thickened interdental gingival tissues in the anterior region was conducted to obtain biopsies for histological confirmation of the observed pathological condition. Results: Histopathological examination validated the diagnosis of drug-induced gingival enlargement, characterized by chorion fibrosis and significant lymphoplasmacytic infiltration. Specifically, parakeratotic and acanthotic characteristics were seen in the gingival epithelium. Adjacent to the inflammatory regions, fibrosis was noted, along with the presence of cytoid bodies, which are typically linked to pathological diseases driven by inflammatory processes. These histological characteristics were consistent with the diagnosis of drug-induced gingival enlargement. Conclusions: A multidisciplinary approach involving the treating physician, dentist, and hygienist, incorporating drug replacement and targeted oral hygiene sessions, is crucial for the management and resolution of calcium channel blocker-induced gingival enlargement.

Background: With an estimated global prevalence rate of over 30%, dental fear is a ubiquitous public health phenomenon. Dental fear’s adverse effects on patient oral health and quality of life are well established; the stresses and financial repercussions it can pose to providers are increasingly recognized. Although dental fear is highly treatable, a disseminable intervention that satisfies the needs of patients and dental care providers has yet to be realized. Objectives: We sought to understand allied dental professionals’ experiences treating patients with dental fear and their impressions of, and receptivity to, a stepped-care approach, including perceived barriers and facilitators to its adoption. Methods: Thirteen semi-structured focus groups comprising students in (a) current dental hygiene programs and (b) other dental programs, who had prior experience working as licensed dental hygienists or allied professionals (i.e., dental assistants, dental therapists, dental treatment coordinators; N = 49) were conducted. Focus group discussions were recorded, transcribed, and thematically analyzed. Results: Participant responses supported the need for innovation in managing dental fear in practices, and supported hygienists as likely facilitators of any new behavioral approach. Overall, participants were receptive to the idea of a stepped-care treatment approach but identified several factors (e.g., accessibility, costs, treatment credibility) that would need to be addressed for its adoption by patients and dental professionals. Conclusion: A stepped-care approach to dental fear treatment has promise to meet the needs of patients and dental professionals. Potential barriers and facilitators to adoption provide a roadmap for future intervention refinement and efficacy testing. Full article

Background: The present study analyzed the relationship between oral motor and cognitive functions in community-dwelling older Korean adults. Methods: Study participants included 113 community-dwelling older adults with a mean age of 73.84 years. Subjects’ cognition was assessed using the Korean version of the Montreal Cognitive Assessment, and tongue, cheek, and lip pressures were assessed using the Iowa Oral Performance Instrument. Tongue and masseter thicknesses were measured using an ultrasound device (Sonon, Healcerion, Roseville, CA, USA). The occlusal force was measured using a specialized device (Innobyte, Kube Innovation, Montreal, QC, Canada), and the number of lost teeth was directly verified by a dental hygienist. Results: Results of analysis of cognitive function according to demographic characteristics of older community-dwelling adults revealed a significant difference in cognitive function according to education level and employment status. Cognitive function demonstrated a positive correlation with oral motor function, including pressure on the cheek, lips, and tongue, thickness of the masseter and tongue, occlusal force, number of lost teeth, and age. Hierarchical regression analysis revealed that demographic characteristics and cheek, lip, tongue, and masseter functions did not affect cognition, whereas occlusal force and number of lost teeth significantly affected cognition. In this study, oral motor function, excluding occlusal force and number of lost teeth, did not affect cognition. Conclusions: Future studies, however, are required to analyze the relationship between oral motor function and cognition in older adults with a wider range of such functions. Full article

Background: Periodontal disease is an inflammatory, chronic, and multifactorial disease. The objective of this study is to analyze the association between periodontal disease and some disorders such as papillomas (benign lesions), lichen planus (a chronic immune-mediated disorder), leukoplakia (potentially malignant lesions), and oral cancer (malignant lesions). Methods: For this study, 42 patients were recruited whose supragingival and subgingival plaque was qualitatively analyzed using a phase-contrast microscope, which allowed for the detection of compatible bacterial flora (immobile and composed mainly of cocci) indicative of periodontal health and incompatible bacterial flora (mobile and composed mainly of spirochetes) indicative of periodontal pathology. Patients with incompatible bacterial flora were then subjected to a laser-assisted periodontal treatment with irrigation with hydrogen peroxide within the periodontal pockets (a non-surgical laser-assisted periodontal protocol which is referred to as dye-free photodynamic therapy). Results: Based on the 42 patients recruited, there was no association between oral cavity lesions and periodontal pathogenic bacteria. Four of them were found to have incompatible bacterial flora. Indeed, it was found that almost all the patients had been previously instructed in the proper techniques of home oral hygiene, and more than half of them reported that they carried out periodic check-ups by a dental hygienist. Of the four patients with signs and symptoms of periodontitis, two stated a willingness to undergo the non-surgical laser-assisted periodontal protocol and showed improvements in periodontal indices such as CAL, PPD, and BoP. Conclusions: hygienists and dentists are determining factors in the prevention of periodontal disease and for the maintenance of good oral health. Full article

This review aims to provide a comprehensive overview of the literature on the oral side effects caused by radiotherapy for head and neck cancers. Various treatments are examined to mitigate these sequelae, and a protocol is proposed for dentists and dental hygienists to manage oncological patients. A literature search was conducted to select relevant articles addressing the effects of radiotherapy treatments on the oral cavity, with a particular focus on the development of mucositis, candidiasis, changes in salivary pH, trismus, fibrosis, and alterations in the oral biofilm. PubMed and MedLine were used as search engines, with keyword combinations including: head and neck cancer, mucositis, candida, dental care, dental hygiene, epidemiology, oral microbiome, biofilm, trismus, fibrosis, and salivary pH. A total of 226 articles were identified, spanning the period from 1998 to 2023. Articles deemed inappropriate or in languages other than English or Italian were excluded. A management protocol for oncological patients was proposed, divided into two phases: home-based and professional. Despite the advancements in intensity-modulated radiation therapy, it is impossible to completely avoid damage to healthy tissues. Preventive education and counseling in the dental chair, ongoing motivation, and education about oral hygiene are crucial to combine a good therapeutic outcome with an improved quality of life for the patient.
