Analysis Of The Soft Tissue Chin Profile In Acceptable Aesthetic Profiles Using A 3-Dimensional Camera Facial Scan System Compared To Normative Values Based On 2-Dimensional Radiographic Analysis, Sasawat Putpinij

Chulalongkorn University Theses and Dissertations (Chula ETD)

Chin profile plays a critical role in determining lower facial aesthetics, significantly affects perceptions of facial balance and attractiveness. Conventional assessment methods, which primarily rely on two-dimensional cephalometric norms, are limited by projection errors and a reduced capacity to accurately evaluate soft tissue contours. The development of three-dimensional facial scanning technology has facilitated more accurate assessment of facial morphology; nevertheless, aesthetic evaluation in acceptable aesthetic profile using 3-dimensional camera facial scan remains no evidence. Hence, this study aimed to investigate soft tissue chin profiles in clinically acceptable facial aesthetics using a three-dimensional camera system, comparing with traditional two-dimensional cephalometric values. …

The Effect Of Multimedia Information About Computer-Assisted And Freehand Dental Implant Surgery On Patients’ Knowledge, Anxiety, And Decision-Making, Veerawit Lukkanasomboon

Chulalongkorn University Theses and Dissertations (Chula ETD)

This study aimed to evaluate the impact of multimedia and verbal information on patients' knowledge, anxiety, and decision-making regarding dental implant surgery, focusing on comparing computer-assisted and freehand techniques. This randomized controlled trial involved 100 patients divided into two groups: one receiving multimedia information (n=50) and the other receiving verbal information (n=50). Data were collected through self-administered questionnaires assessing patients' baseline information, knowledge, anxiety, and decision-making before and after receiving information about dental implant surgery techniques. Results showed significant increases in knowledge scores for both groups, with the multimedia group improving from 1.96 to 3.90 (p<0.001) and the verbal group from 2.0 to 3.98 (p<0.001). Anxiety levels decreased significantly in both groups, with reductions from 12.76 to 11.48 (p=0.001) in the multimedia group and from 13.92 to 12.16 (p<0.001) in the verbal group. The proportion of patients who decided to proceed with dental implant surgery increased from 70% to 78% in the multimedia group and from 54% to 66% in the verbal group. After receiving the information, more patients in both groups opted for computer-assisted implant surgery, though treatment costs remained a significant concern for some, leading to declines in surgery acceptance. Despite these findings, no significant differences were observed between the multimedia and verbal groups regarding knowledge improvements, anxiety reduction, or decision-making. In conclusion, multimedia and verbal information effectively enhanced patient knowledge and reduced anxiety about dental implant surgery, and both methods may influence patients' decisions regarding their preferred implant technique, with no significant differences between the two methods.

Accuracy Of Intraoral Scanner For Centric Relation Record In Comparison To Vinyl Polysiloxane, Rawinan Luangsukrerk

Chulalongkorn University Theses and Dissertations (Chula ETD)

The study aimed to compare the accuracy of digital centric relation (CR) recordings from intraoral scanners with conventional CR bite registration through a quantitative comparison of occlusal contacts. This cross-sectional study involved 29 healthy adults. CR was recorded using the bimanual manipulation technique, guided by silicone bite indexes (Silagum-Putty; DMG, Germany). Conventional bite registrations were made with vinyl polysiloxane (O-Bite; DMG, Germany), and digital interarch relationships were captured using an intraoral scanner (iTero Element 2; Align Technologies, USA). The maxillary and mandibular arches were digitized with the intraoral scanner, and CR was recorded through the silicone bite index. Each recording …

Cbct Perceptions Of Radiology Leaders In The Midwest Dental Schools: A Qualitative Study, Tenzin Dadul

Dissertations

Problem

The integration of Cone Beam Computed Tomography (CBCT) in dental education is hindered by a lack of formal training among radiology leaders, insufficient institutional support, and financial constraints. Despite the proven efficacy of CBCT in enhancing diagnostic accuracy and treatment planning, its adoption in pre-doctoral curricula remains limited. This gap in education poses significant challenges for dental graduates, who are increasingly expected to utilize advanced imaging technologies in clinical practice.

Purpose of Study

This qualitative study aimed to explore the perceptions of radiology leaders in Midwest dental schools regarding the integration of CBCT education into pre-doctoral curricula. The objectives …

Clinical Significance Of Gutta Percha Variability, Alex R. Pancake

Graduate Theses, Dissertations, and Problem Reports (ETD)

Introduction: The production of gutta percha points as root canal therapy filling materials vary from hand processing to machine processing with a range of acceptable levels of error (tolerance). Similarly, endodontic files manufactured to complement corresponding gutta percha points exhibit specified levels of tolerance. Investigations into the consistency among manufacturers of files and gutta percha points is limited. The aim of this study is to see how variability in apical gauge and taper of gutta percha points affected the clinical performance during cone try in. The null hypothesis of this study is that there is no difference in two gutta …

Advocacy Spotlight: Telehealth Regulations For Dentistry Established, Neema Katibai Jd

The Journal of the Michigan Dental Association

The article discusses the rise of telehealth in the last three years and its implications for dentistry, focusing on recent rulemaking by the Michigan Board of Dentistry. The regulations address key aspects such as definitions, informed consent, scope of practice, and prescribing medications. Dentists must comply with HIPAA and state/federal privacy regulations when using telehealth. Notably, the rules restrict teledentistry delegation to allied personnel after an in-person visit within 24 months. The article emphasizes the importance of understanding and following these regulations for legal telehealth use, reimbursement, and malpractice coverage. The Michigan Dental Association advocates for sensible teledentistry laws to …

Staff Matters: Are There Risks To Using Ai In Our Practice?, Jodi Schafer Sphr, Shrm-Scp

The Journal of the Michigan Dental Association

As your practice adopts AI for hiring processes, it brings efficiency but also potential pitfalls. The increasing use of AI, such as ChatGPT, streamlines tasks like resume screening, but caution is essential. Recent executive orders emphasize safety assessments and civil rights in AI. The Equal Employment Opportunity Commission focuses on transparency and consent in recruitment AI use. Legal compliance is vital to prevent discrimination; criteria like education and experience must be applied consistently. Additionally, employee monitoring AI requires careful implementation, ensuring transparency and human oversight. While AI offers benefits, its workplace integration demands careful consideration, testing, and ongoing evaluation.

Zeitlin’S Top 200 Dental Deckades (January 2024), Benjamin D. Zeitlin

Pacific Open Texts

Pharmacology courses in any institution are information intensive with a constant, high volume of new material. With that in mind, the standards that the American Dental Education Association set for Pharmacology include that: “the student must identify the influences drugs taken for non-dental purposes may have on a proposed treatment (…) and the student must recognize therapeutic agents used in the routine practice of clinical dentistry.” This requires that students at a minimum, recognize common drugs and know their major implications for dental therapy.

This learning tool has been created to address the drug recognition aspect of that standard.
