However, widespread gaps in academic literacy, particularly in reading comprehension, writing, and research synthesis, pose significant challenges for undergraduate DH students transitioning from novice learners to competent practitioners. This short report examines the role of academic literacy as a foundational component of DH education and its alignment with the Commission on Dental Accreditation (CODA) standards. Drawing on evidence from nursing and allied health education, this paper highlights strategies to strengthen academic literacy through curriculum innovation, including writing-enriched curricula, scaffolding assignments, active learning, portfolio assessment, and the ethical integration of generative artificial intelligence. Additionally, the importance of faculty development, interprofessional collaboration, and librarian partnerships are emphasized to support both teaching efficacy and student success. By embedding academic literacy longitudinally across the curriculum, DH programs can better prepare undergraduates to engage in research, think critically, and deliver high-quality, person- centered care. Advancing academic literacy supports not only accreditation standards but also creates a foundation for the development of future leaders, educators, and researchers in the dental hygiene profession.</p>","PeriodicalId":52471,"journal":{"name":"Journal of dental hygiene : JDH / American Dental Hygienists'' Association","volume":"100 3","pages":"68-74"},"PeriodicalIF":0.0,"publicationDate":"2026-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148145577","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The purpose of this study was to evaluate the knowledge, confidence, and willingness to implement dental anxiety management techniques (DAMTs) by dental hygienists (DHs) in North Carolina (NC) as well as the types of DAMTs currently being used by DHs in NC.<b>Methods</b> This cross-sectional study utilized an electronic survey of DHs licensed to practice in NC. An email list provided by the NC Dental Board was used to invite all dental hygiene licentiates (N=7,732) to participate. The 32-item survey included multiple-choice, select-all, Likert-scale, and open-ended on the following categories: demographics, knowledge, education, clinical experience, confidence to treat, and willingness to implement DAMTs. Descriptive statistics, multivariate analysis (<i>p</i><0.05), and thematic analysis were used for data interpretation.<b>Results</b> A total of 632 NC DHs completed the survey for a response rate of 8.17%. Most (99%, n=622) reported treating a patient with dental anxiety. Over one-third (36%, n=214) reported a lack of education on DAMTs at their educational institution and poor preparation in utilizing DAMTs post-education (4.90 on a 0-10 scale). Verbal DAMTs were more frequently learned during education by participants aged 18-34 compared to participants aged 55+ (<i>p</i><0.0001).

The purpose of this scoping review was to determine the amount of literature regarding the use of dental radiographs for calculus detection and removal following nonsurgical periodontal therapy.<b>Methods</b> The following questions guided the review: 1) To what extent are radiographs incorporated into clinical practice for calculus detection and what factors influence their use or limitations? 2) What role do radiographs play in verifying the effectiveness of calculus removal during periodontal therapy? 3) Should a protocol or clinical guideline for use of dental radiographs post-nonsurgical periodontal therapy be considered? Following PRISMA guidelines, an online search of PubMed, CINAHL, Cochrane Database of Systematic Reviews, JBI EBP Database, and Web of Science was conducted. Inclusion criteria were studies conducted on the presence of dental calculus, calculus detection, calculus removal and evaluation methods. Studies with a sample size of fewer than thirty, studies on implants, animals, in vitro studies, and research that did not include calculus detection or removal in the topic were excluded from the review.A total of 346 articles underwent title and abstract screening by three separate reviewers for assessment against the inclusion criteria for the review.<b>Results</b> A total of 59 studies met the inclusion criteria for the scoping review. Only two of the articles explicitly mentioned using radiographs to detect calculus. While a wide range of techniques were employed for calculus detection and removal, no single method was universally effective, and many studies acknowledged the persistent challenge of residual calculus post-nonsurgical periodontal treatment.<b>Conclusion</b> When combined with traditional calculus detection methods, the use of radiographs alone, or in combination with AI techniques, may prove beneficial post-nonsurgical periodontal therapy. While the concept of assessing subgingival calculus via radiographs is not novel, findings highlight a significant gap in the literature validating its effectiveness. Additionally, research on AI assisted radiographic calculus detection should be focused on in-vivo studies to reflect real scenarios and whether these techniques improve patient outcomes.</p>","PeriodicalId":52471,"journal":{"name":"Journal of dental hygiene : JDH / American Dental Hygienists'' Association","volume":"100 3","pages":"34-46"},"PeriodicalIF":0.0,"publicationDate":"2026-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148145619","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Examples of these lesions include dentigerous cyst, radicular cyst, odontogenic keratocyst, and ameloblastoma. Many of these lesions require a histologic examination to render the definitive diagnosis. In terms of the ameloblastoma, there are four distinct types of this tumor. These include the conventional ameloblastoma, unicystic ameloblastoma (UA), extraosseous/peripheral ameloblastoma, and metastasizing ameloblastoma. The purpose of this report is to present a case report of a unicystic ameloblastoma found in a 30-year-old female who presented to a general dental practice with a chief complaint of pain and swelling in the mandibular left third molar region. Further evaluation and eventual surgical excision were delayed due to misdiagnosis and delay in performing the biopsy. The definitive diagnosis for this lesion was a benign unicystic ameloblastoma (UA). Due to the size of the defect, the patient required a partial mandibulectomy, reconstructive surgery and placement of two dental implants. While the long-term prognosis for this patient is good, regular surveillance is needed as UA neoplasms have a high recurrence rate.
