Validation of the Polish version of an Ageism Scale for Dental Students (ASDS-PL).

BACKGROUND: Ageism is one of the common forms of discrimination and prejudice. It has also been shown to be present in health professionals, including doctors, nurses, and medical students. AIMS: The aim of this study was to translate the Ageism Scale For Dental Students (ASDS) into Polish, perform a culture adaptation, and conduct a preliminary validation analysis. METHODS: The survey was administered to 202 third-, fourth-, and fifth-year students at the Jagiellonian University (No. 1072.6120.283.2020). Data were analyzed using principal components analysis (PCA) with an oblique, Promax rotation, and confirmatory factor analysis (CFA). Cronbach's alpha (α) was calculated to check the internal consistency reliability. Discriminant validity was analyzed using the Mann-Whitney and Kruskal-Wallis test. RESULTS: PCA produced a 10-item scale distributed into three factors, which explains 59.52% of the total variance. Factor 1 ("preconceived notions about dental treatment") contained four items (α = 0.703), Factor 2 ("cost-benefit of providing care for older patients")-four items (α = 0.660) and Factor 3 ("dentist-older patient interaction")-two items (α = 0.662). CFA confirmed that the model is a good fit (RMSE = 0.058, 90% CI from 0.014 to 0.092, CFI = 0.950, and TLI = 0.926). The discriminant validity showed statistically significant differences in factors or individual items related to the year of the study, gender, and having a history of living with an older person(s) or an older patient(s) treated. CONCLUSION: The validation of the ASDS conducted in Poland identified 10 items with sufficient validity and reliability.

Big Data in Epidemiology: Brave New World?

Epidemiology is experiencing a significant shift toward the utilization of big data for health monitoring and decision-making. This article discusses the recent example of the World Health Organization (WHO) global oral health status report and regional summaries, which faced criticisms due to its reliance on big data from the Global Burden of Disease (GBD) study. We address the arguments for and against the use of big data in epidemiology and provide an assessment of the value and limitations of big data epidemiology. Moreover, we provide recommendations as to how the oral health community should reconcile traditional epidemiologic approaches with big data and advanced data analytics. This Perspective article highlights the challenges of the current epidemiologic landscape, the potential of big data, and the need for a balanced approach to data utilization in epidemiology.

Towards dental diagnostic systems: Synergizing wavelet transform with generative adversarial networks for enhanced image data fusion.

The advent of precision diagnostics in pediatric dentistry is shifting towards ensuring early detection of dental diseases, a critical factor in safeguarding the oral health of the younger population. In this study, an innovative approach is introduced, wherein Discrete Wavelet Transform (DWT) and Generative Adversarial Networks (GANs) are synergized within an Image Data Fusion (IDF) framework to enhance the accuracy of dental disease diagnosis through dental diagnostic systems. Dental panoramic radiographs from pediatric patients were utilized to demonstrate how the integration of DWT and GANs can significantly improve the informativeness of dental images. In the IDF process, the original images, GAN-augmented images, and wavelet-transformed images are combined to create a comprehensive dataset. DWT was employed for the decomposition of images into frequency components to enhance the visibility of subtle pathological features. Simultaneously, GANs were used to augment the dataset with high-quality, synthetic radiographic images indistinguishable from real ones, to provide robust data training. These integrated images are then fed into an Artificial Neural Network (ANN) for the classification of dental diseases. The utilization of the ANN in this context demonstrates the system's robustness and culminates in achieving an unprecedented accuracy rate of 0.897, 0.905 precision, recall of 0.897, and specificity of 0.968. Additionally, this study explores the feasibility of embedding the diagnostic system into dental X-ray scanners by leveraging lightweight models and cloud-based solutions to minimize resource constraints. Such integration is posited to revolutionize dental care by providing real-time, accurate disease detection capabilities, which significantly reduces diagnostical delays and enhances treatment outcomes.

Understanding the role of a general education course Oral Science in establishing oral health knowledge and behaviors among undergraduate students from different majors: a questionnaire-based study.

BACKGROUND: The general education course, Oral Science, has been offered by Guanghua School of Stomatology, Sun Yat-sen University for many years in order to improve students' knowledge of oral health. Information about the oral health knowledge, status, and behaviors among undergraduates who had taken Oral Science was collected to evaluate the impact of this course, and to provide a basis for further improvement of the course teaching quality. METHODS: Undergraduates taking Oral Science as an elective course were selected as the research subjects. The research time is the second semester of the 2022 academic year, from February 2023 to June 2023. Undergraduates who had not taken the course served as the control group. To investigate the oral health knowledge, status, and behaviors among undergraduate students who have taken the general education course of Oral Science, course students and non-course students were asked to fill out the same questionnaire at both the beginning and end of semester. The answer scores and accuracy of these two groups were compared and analyzed. Before and after the first lesson, and at the end of the semester, course students were asked to fill out the same oral knowledge questionnaire. Another questionnaire was released in week 10 to collect the data of the course students' oral health status and behaviors. The control group completed the same oral knowledge questionnaire at the beginning and end of the semester, respectively. SPSS 20.0 statistical software was used to analyze the data. Statistical significance level was set at 0.05 for all tests. RESULTS: At the beginning of the semester, there was no significant difference in the accuracy of the 16 questions nor the scores between two groups (P > 0.05). After one semester of learning, the accuracy of the 16 questions answered by the course students at the end of the semester was significantly higher (P < 0.05), as well as the score of the course students. CONCLUSION: The general education course of Oral Science can significantly improve undergraduates' general knowledge of dentistry and effectively improve their oral hygiene behavior.

The Impact of Orthodontic Adhesive Containing Resveratrol, Silver, and Zinc Oxide Nanoparticles on Shear Bond Strength: An In Vitro Study.

Introduction The goal of orthodontic treatment is to provide patients with esthetic smiles and functional occlusion. Despite best efforts and continuous evolution of materials, white spot lesions present a persistent hindrance to the desired treatment outcome. Nanoparticles have shown efficacy in reducing microbial activity; however, currently, there is a need for natural anti-cariogenic compounds with minimal side effects. Resveratrol is a natural compound belonging to the polyphenol group and has shown promising anti-microbial efficacy. This study aimed to evaluate the influence of dentin bonding agents incorporated with the following three different nanoparticles on shear bond strength: silver nanoparticles (Ag-Np), zinc oxide nanoparticles (ZnO-Np), and resveratrol nanoparticles (RSV-Np). Materials and methods A total of 40 premolar teeth therapeutically extracted were assigned to four equal groups of n=10 each. Groups 1, 2, and 3 used experimental adhesives doped with silver, zinc oxide, and resveratrol nanoparticles, respectively. Group 4 was bonded using unmodified adhesive. The bonded teeth were then subjected to shear bond strength (SBS) testing which was measured using a Universal Testing Machine (model no. UNITEST-10; Pune, India: ACME Engineers). Statistical analyses were performed using SPSS version 21 (Armonk, NY: IBM Corp.), employing one-way ANOVA and Tukey's post-hoc test for pairwise comparisons. Results Shear bond strength testing revealed that the control group with unmodified adhesive (8.6 MPa) had the highest SBS, followed by RSV-Np (7.6 MPa), Ag-Np (6.3 MPa), and ZnO-Np (5.65 MPa). Although the experimental groups demonstrated decreased SBS compared to the control, the values for Ag-Np and RSV-Np fell within the acceptable range. Conclusion Resveratrol nanoparticles had the least impact on shear bond strength among the experimental groups. These findings suggest that the incorporation of resveratrol nanoparticles in dentin bonding agents can provide anti-cariogenic effect without significantly impacting the adhesive's mechanical properties thereby providing a new and promising alternative to synthetic nanoparticles. Further studies are recommended to optimize the balance between anti-microbial efficacy and bond strength in clinical applications.

Exploring Dental Fusion in Primary Dentition: A Pediatric Dental Perspective.

Developmental anomalies of dentition includes abnormalities in teeth size, shape, structure, and number. Dental fusion is one such condition and is one of the most important and frequent developmental dental anomalies that can affect children's oral health. This condition can present various clinical challenges, including aesthetic concerns, occlusal disturbances, and potential impacts on the development and eruption of permanent teeth. The etiology of dental fusion is multifactorial, involving genetic, environmental, and possibly mechanical factors during tooth development. Diagnosis is done based on clinical examination and radiographic imaging to differentiate fusion from other similar anomalies such as gemination and concrescence. The present case report describes dental fusion in primary teeth seen in two young pediatric patients. These case reports aim to provide an overview of the prevalence, diagnosis, and management strategies for fusion in primary teeth, emphasizing the importance of a Pediatric Dentist in optimizing outcomes for affected children.

In vitro evaluation of some mechanical properties and fluoride release of glass-ionomer cement modified with seashell nanoparticles.

Background: This research assessed the compressive strength and microhardness of glass-ionomer cement (GIC) after incorporating seashell nanoparticles and evaluated the inert fluoride-releasing ability. Methods: Seashell nanoparticles were synthesized by a mechanical grinding protocol. These particles were characterized by transmission electron microscopy and energy dispersive x-ray and added to the glass-ionomer powder in a weight-to-weight ratio. Seventy-five study samples were distributed into eight samples for each study group (control, 5%, and 10% seashell) to have 24 samples for each test of the study (compressive strength, microhardness, and fluoride release). One sample per group was prepared for the Fourier transform infrared spectroscopy (FTIR) test. The fluoride ion release was measured after one and four weeks of incubation period at 37 ºC, while other tests were conducted after 24 hours of incubation. Results: In all the test variables, the 10% seashell group showed the highest significant mean, followed by the 5% seashell and the control group. However, there was no significant difference between the 5% and 10% seashell groups in the first week of fluoride release. Conclusion: According to the results, 10% seashell nanoparticles were the best to improve the mechanical properties of GIC and boost the fluoride-releasing potential.

General dentists' treatment plans in response to cosmetic complains; a field study using unannounced-standardized-patient.

Background: This field study explored general dentists' treatment plans in response to the request for cosmetic services of an unannounced standardized patient (USP) in Mashhad, Iran. Methods: The researcher, as a USP, visited 24 and 23 offices in a high-income and a low-income area, respectively. The primary complaint was that, according to her friend's comments, a dental student, her smile was "crooked and yellow" due to the congenitally missing tooth number 10 and peg-shaped tooth number 8. The dentists' treatment plans for teeth color and form and the cosmetic services expenses were recorded. The treatment plans of the two areas were compared. Results: For dental form, most dentists' treatment plans were categorized as "No intervention" (privileged area: 37.5 %, less-privileged area: 56.53 %, and total: 46.80 %). The percentage of dentists in the privileged area who prescribed cosmetic services was twice that of the less-privileged area (33.33 % versus 17.39 %). The intervention for dental form varied from placing 1 unit of composite veneer to 10 units of ceramic laminates or orthodontics with a wide range of treatment costs ($42.09 to $1079.14). For tooth color, most dentists (privileged area: 62.50 %, less-privileged area: 30.43 %, and total: 46.80 %) were categorized as "Interventionists." For tooth color, the treatment plans varied from scaling and root planing, bleaching, and composite veneer with various costs ($7.19 to $197.84). Conclusion: Cosmetic treatment plans and expenses varied significantly for a single USP, with many not aligning with the standard treatment plan. Some dentists offered treatments even without a chief complaint from the patient. Dentists in privileged areas were twice as likely to prescribe cosmetic treatments compared to those in less privileged areas. Therefore, cosmetic services necessitate monitoring, establishing clear diagnostic criteria, and implementing educational interventions.

A Comparison of Conventional Root Canal Sealers With Ones That Use Green Synthesized Nanoparticles for Antimicrobial Activity: Protocol for a Systematic Review.

BACKGROUND: Root canal failure and secondary endodontic infection are frequent clinical scenarios in dentistry. The main microorganisms implicated in root canal therapy failure are persistent Enterococcus faecalis, Candida albicans, and Staphylococcus aureus. To combat the impact of disease resistance, scientists are concentrating on alternative antimicrobial root canal sealers. Nanomaterials are a recent development in endodontic materials that exhibit great antimicrobial properties, making them an ideal material choice for root canal sealers. OBJECTIVE: This systematic review aims to compare the antimicrobial properties of conventional root canal sealers to those incorporating green synthesized nanoparticles between 2010 and 2024. METHODS: A well-constructed protocol was established and registered with PROSPERO (CRD42021286373). Ethics approval was obtained from the Biomedical Research and Ethics Committee from the University of the Western Cape (UWC; BM22/1/4). PRISMA-P (Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols) reporting guidelines were followed. The included criteria demonstrate the green synthesized nanoparticles studies where the nanoparticles (NPs) are incorporated in root canal sealers. MeSH (Medical Subject Headings) terms were used for the search strategy of the systematic electronic databases for articles published in English between 2010 and 2024. The selected databases included Scopus, PubMed, Web of Science, Science Direct, EBSCOhost, SpringerLink, and Wiley Online. A quality assessment tool for laboratory studies will be used to critically appraise the included studies. If applicable, statistical measures (mean, SD, etc) will be used for data analysis and presentation of the results. RESULTS: The protocol is registered with PROSPERO. A preliminary search was conducted using a determined search strategy across 8 electronic databases, and the review is now complete. CONCLUSIONS: It is anticipated that the results of this systematic review may reveal the increased interest and application for nanoparticle-enhanced root canal sealers. This will aid in the future development of root canal sealants and mitigate the risk of endodontic failure. TRIAL REGISTRATION: PROSPERO CRD42021286373; https://www.crd.york.ac.uk/prospero/display_record.php?RecordID=286373. INTERNATIONAL REGISTERED REPORT IDENTIFIER (IRRID): DERR1-10.2196/51351.

Automated orofacial virtual patient creation: A proof of concept.

OBJECTIVES: To (1) construct a virtual patient (VP) using facial scan, intraoral scan, and low-dose computed tomography scab based on an Artificial intelligence (AI)-approach, (2) quantitatively compare it with AI-refined and semi-automatic registration, and (3) qualitatively evaluate user satisfaction when using virtual patient as a communication tool in clinical practice. MATERIALS AND METHODS: A dataset of 20 facial scans, intraoral scans, and low-dose computed tomography scans was imported into the Virtual Patient Creator platform to create an automated virtual patient. The accuracy of the virtual patients created using different approaches was further analyzed in the Mimics software. The accuracy (% of corrections required), consistency, and time efficiency of the AI-driven virtual patient registration were then compared with the AI-refined and semi-automatic registration (clinical reference). User satisfaction was assessed through a survey of 35 dentists and 25 laypersons who rated the virtual patient's realism and usefulness for treatment planning and communication on a 5-point scale. RESULTS: The accuracy for AI-driven, AI-refined, and semi-automatic registration virtual patient was 85 %, 85 %, and 100 % for the upper and middle thirds of the face, and 30 %, 30 %, and 35 % for the lower third. Registration consistency was 1, 1 and 0.99, and the average time was 26.5, 30.8, and 385 s, respectively (18-fold time reduction with AI). The inferior facial third exhibited the highest registration mismatch between facial scan and computed tomography. User satisfaction with the virtual patient was consistently high among both dentists and laypersons, with most responses indicating very high satisfaction regarding realism and usefulness as a communication tool. CONCLUSION: The AI-driven registration can provide clinically accurate, fast, and consistent virtual patient creation using facial scans, intraoral scans, and low-dose computed tomography scans, enabling interpersonal communication. CLINICAL SIGNIFICANCE: Using AI for automated segmentation and registration of maxillofacial structures leads to clinically efficient and accurate VP creation, opening the doors for its widespread use in diagnosis, treatment planning, and interprofessional and professional-patient communication.

Influence of temperament on children's cooperation during dental treatment.

Background: The etiologies of childhood dental fear/dental behavior management problems have been extensively studied, especially the role of children's temperaments. This study aimed to evaluate the effect of temperament and its associated variables on the anxiety and cooperation level of preschool children in a dental clinic. Materials and Methods: This cross-sectional study involved 103, 4-6-year-old patients (39 boys and 64 girls). The children's parents or guardians completed the Child Fear Survey Schedule (CFSS) Dental Subscale and the Malhotra temperament questionnaire before the treatment. Patients' anxiety and cooperation levels were then assessed through three distinct treatment stages of fluoride therapy, injection of local anesthesia, and drilling, by applying the Venham anxiety and clinical cooperation scales. The data were analyzed using analysis of variance, Mann-Whitney, Kruskal-Wallis, and Chi-square tests. The significance level of 0.05 was deemed relevant in the analysis. Results: A significant correlation was established between the mean of CFSS and the variety of temperament (P = 0.001). Anxiety and uncooperative behavior during injection and drilling were strongly related to lower sociability scores. Furthermore, higher anxiety during the drilling stage was related to higher impulsivity scores. Conclusion: The evaluation of children's anxiety and cooperation in dental clinics heavily relies on temperament and certain related factors, such as sociability. These variables serve as crucial benchmarks in understanding and assessing the psychological state of children during dental procedures.

Myofibroma with Atypical Features can Mimic Low-Grade Myofibroblastic Sarcoma: Two Paediatric Cases.

Myofibroma is a rare benign mesenchymal tumor that frequently affects the pediatric population with a predilection for the head and neck region. About 10% of myofibroma cases, presenting atypical features, can be misinterpreted as low-grade myofibroblastic sarcoma (LGMS), with therapeutic and prognostic impact. Here, we report two pediatric cases of benign myofibroblastic tumors, one of them showing typical characteristics of myofibroma, the other was an atypical myofibroma, which initially mimicked low-grade myofibroblastic sarcoma. Atypical myofibromas, despite its distinctive characteristics, follow a benign course, similar with typical myofibroma. It is necessary to distinguish atypical myofibroma from low-grade myofibroblastic sarcoma and avoid unnecessary invasive therapy.

Attitudes and practices of radiation protection among Jordanian dental radiography practitioners.

INTRODUCTION: Varying radiation protection practices have been documented in the literature. This study aims to evaluate the attitudes and practices of dental radiography practitioners towards radiation protection in Jordan, as no data currently explores their understanding and practices in this area. METHODS: The survey involved 192 dental radiography practitioners. A cross-sectional, self-administered questionnaire containing 43 questions covered socio-demographic data, practices towards radiation protection, and attitudes. RESULTS: The majority of participants were less than 40 years old (87.5 %), with 66.7 % working in private clinics and 53.6 % based in the capital city of Jordan. Nearly a quarter (26.5 %) of the practitioners used an X-ray tube voltage of 65-70 kVp; however, 14.6 % were unaware of the X-ray tube voltage used in their machines. Additionally, almost one quarter of the participants never or rarely used light beam positioning aids and available positioning guides in panoramic radiography practice. Only 33.3 % of practitioners consistently used lead aprons, with the main reasons for non-use being the weight of the apron or its unavailability. About 81 % of participants believed in spreading awareness about radiation protection and applying this knowledge in their daily practices. CONCLUSIONS: The study found that the practitioners' practices were satisfactory to some extent, supported by a positive attitude towards radiation protection. The participants understand the importance of increasing their awareness and knowledge of radiation protection practices. IMPLICATIONS FOR PRACTICE: The findings of this study highlight the need to improve radiation protection practices among dental radiography practitioners in Jordan by introducing standard dose protocols, supporting the transition to digital systems, establishing diagnostic reference levels, and encouraging the use of equipment over staff holding practices, and raising awareness about radiation safety.

Use of a Novel Artificial Intelligence Approach for a Faster and More Precise Computerized Facial Evaluation in Aesthetic Dentistry.

INTRODUCTION: AI is based on automated learning algorithms that use large bodies of information (big data). In the field of dentistry, AI allows the analysis of radiographs, intraoral images and other clinical recordings with unprecedented precision and speed. Facial analysis is known for helping dentists and patients achieve a satisfactory result when a restorative treatment must be realized. The objective of this study is to conduct a neural network-based computerized facial analysis using Python programming language in order to valuate its efficacy in facial point detection. METHODS: The neural network was trained to identify the main facial and dental points: smile line, lips, size and for of the teeth, etc. A facial analysis was carried out using AI. A descriptive analysis was made with calculation of the mean and standard deviation (SD) of the precision and accuracy in each group. Analysis of variance (ANOVA) was used for the comparison of means between groups. RESULTS: At the intersecting point between dentistry and technology, advances in artificial intelligence (AI) are producing a change in the way modern dentistry is performed. The present study evidenced lesser variability in the execution times of the neural network compared with the DSD system. This indicates that the neural network affords more consistent and predictable results, representing a significant advantage in terms of time and efficacy. CONCLUSION: The neural network is significantly more efficient and consistent in performing facial analyses than the conventional DSD system. The neural network reduces the time needed to complete the analysis and shows lesser variability in its execution times.

Enhanced alveolar ridge preservation with hyaluronic acid-enriched allografts: a comparative study of granular allografts with and without hyaluronic acid addition.

PURPOSE: Ridge preservation is essential to restore alveolar ridge volume and to enhance esthetic and functional outcomes for dental implants. The addition of hyaluronic acid to allogeneic bone substitute materials might enhance these outcomes. This clinical study evaluated the efficacy of ridge preservation after tooth extraction using granular allografts with and without hyaluronic acid addition. METHODS: In this retrospective study, 40 patients with compromised extraction sockets were enrolled. Among them, 19 received particulate allogeneic bone substitutes (Allo), 21 received allogeneic bone substitutes with hyaluronic acid (AlloHya). Vertical and horizontal graft stability, graft shrinkage rate, and bone mineral density were assessed using radiographic measurements on CBCT scans conducted before tooth extraction, directly after ridge preservation and after four months. Patients were followed up 12 months post-implantation. RESULTS: Vertical height loss after 4 months was significantly greater in the Allo group (-0.82 ± 0.95 mm) compared to the AlloHya group (-0.19 ± 0.51 mm; p = 0.011). Graft shrinkage rate was 16.9 ± 11.5% (Allo) and 10.3 ± 7.7% (AlloHya) (p = 0.038). After four months, average bone density was significantly higher in the AlloHya compared to the Allo group (p = 0.004). Nearly all implants (39 out of 40) were classified as "Success" according to the ICOI scheme, with no differences in implant quality between the two study groups. CONCLUSIONS: Improved graft stability, reduced resorption, and increased bone density were observed in hyaluronic acid-enriched allografts compared to pure allografts. Adding hyaluronic acid to allogeneic bone grafts significantly enhanced outcomes in ridge preservation.

Use of Hypnosis in the Treatment of Orofacial Pain: A Systematic Review.

Objectives: To conduct a systematic review on the use of hypnosis in the treatment of orofacial pain. Methods: The search was performed on February 2021 and updated in July 2024 in the following databases: MEDLINE via PUBMED, Virtual Health Library (VHL), Web of Science, Cochrane Library, Embase, Clinical Trials, ISRCTN Registry, Psycinfo, Open Grey, Google Scholar, and Brazilian Digital Library of Theses and Dissertations (BDTD). The descriptors referring to Orofacial Pain and hypnosis were used to select clinical trials on the use of hypnosis in the treatment of Orofacial Pain, in English, Spanish, Portuguese, French, and Italian, without restriction on date and place of publication. In a first stage, two independent, trained, and calibrated reviewers classified the abstracts and then the full texts. The data were extracted, and the risk of bias was assessed using the Cochrane RoB 2.0 tool. Results: Of the 642 references identified, 6 studies-published between 1986 and 2010-were included in the review, with 232 patients reported. Hypnosis was mainly used in cases of chronic pain associated with temporomandibular disorders (TMDs), compared with relaxation sessions, acupuncture, occlusal splint, minimal treatment, or no interference. Hypnotherapy was applied in different ways, either exclusively by professionals or by means of self-hypnosis in a complementary or exclusive manner. All studies showed statistical significance for the effect of the intervention (hypnotherapy). The overall RoB2 consisted of three studies with high risk of bias and three studies with some concern. Conclusions: Although there were clinical studies on the subject and they had methodological flaws, hypnotherapy (induction and/or self-hypnosis) appears to be a promising strategy for the treatment of orofacial pain, especially TMDs. There is, therefore, a need for new randomized clinical studies with adequate methodological standards to confirm the findings.

This article explores the transformative shift towards digital workflows, highlighting the collaborative dance between the clinician and the dental laboratory. The power of visual communication is emphasised, with examples illustrating its impact on the precision of treatment plans. Celebrating these digital tools, this article envisions a new era of collaboration, transcending traditional communication methods for more predictable and successful implant restorations.

The hygienist's role in the management of the implant patient in primary care.

The scope of practice for dental hygienists includes the care of implants and peri-implant tissues. Hygienists in primary care settings must therefore be competent and confident in assessing, managing, and treating implant restorations and their peri-implant health. Dental hygienists also play a key role in the education of patients on oral health as part of their daily practice, a recognised and valued aspect of their clinical care responsibilities. Dental hygienists and therapists therefore have a pivotal role as adjunct support in a patient's implant journey where they can offer essential support throughout their treatment period and can provide guidance and education at regular intervals.Using current guidelines, dental hygienists and therapists can create and implement practice protocols to help deliver the necessary clinical care during pre-implant, peri-implant, and post-implant phases of care. This article discusses the processes required to achieve a healthy implant patient, how the dental team can support the patient, and how clinicians can work together to achieve the best possible clinical outcome. This article will explore current evidence-based guidance and how to implement guidance in a practice setting, with protocols for all members of the dental team, with the final goal of a dentally healthy, motivated patient.
