Comparison of trueness and repeatability of facial prosthesis design using a 3D morphable model approach, traditional computer-aided design methods, and conventional manual sculpting techniques.

Statement Of Problem: Manually sculpting a wax pattern of a facial prosthesis is a time-, skill-, and resource-intensive process. Computer-aided design (CAD) methods have been proposed as a substitute for manual sculpting, but these techniques can still require high technical or artistic abilities. Three-dimensional morphable models (3DMMs) could semi-automate facial prosthesis CAD.

Supportive periodontal care in dental practice: Part 1 - the importance and implications for general dental practitioners.

Supportive periodontal care is an essential component of maintaining the outcome of periodontal treatment. It is essential to ensure cost benefit to both patients and the health services where millions are spent on treating patients with periodontal disease. The dentist must be able to recognise the crucial and important role they play in providing supportive care and therapy to periodontally compromised patients, either independently or as part of a wider dental team, over and above the various challenges they may experience in the provision of such care in general dental practice.

Supportive periodontal care in dental practice: Part 2 - perceptions of locally referring UK general dental practitioners.

Background Supportive periodontal care (SPC) is important in maintaining periodontal treatment outcomes. Hospital services provide specialist periodontal care at high costs. On completion of treatment, patients are discharged back to the general dental practitioner (GDP) to provide SPC.

Assessment of the Micro-Tensile Strength of the Composites for the Various Antioxidants: An Study.

Introduction: The application of the antioxidants after the teeth are bleached has been advocated to fasten the restorative process post-bleaching. The motive of this study was to examine and assess the micro-tensile binding strength of bleached enamel to the resin using a variety of antioxidant solutions. Finding the reason for the tooth fracture was the secondary outcome measured.

A CBCT Assessment of Orthodontic Mini-Implant Placement.

Objectives: This study compares the precision of cone beam computed tomography (CBCT) and two-dimensional radiography for mini-implant implantation.

Materials And Method: For 30 sites (in 15 patients between the ages of 13 and 26 years), the buccal interradicular region among the 2 premolar and 1 molar was found to be the best location for mini-implants. Next, two groups of the mini-implant implantation process were created.

A Light Microscopic Study Comparing Pulp Histological Alterations Following Tooth Preparation Using a High-speed Handpiece and an Er: YAG Laser.

Introduction: Histological alterations were evaluated in this study after tooth preparation with carbide burs using a traditional handpiece and Er: YAG laser.

Methods: Tooth preparation was done on 30 intact maxillary first premolars of healthy patients. Ten maxillary first premolars were used as control, wherein no tooth preparation was done.

Estimation of Loss of Crestal Bone Around Dental Implants in Various Tissue Biotypes Using CBCT.

Objectives: To evaluate the loss of crestal bone height around dental implants placed in various tissue biotypes.

Materials And Methods: 20 patients with single edentulous sites were allocated randomly, with 10 samples in each into Group I (implants were placed in thick tissue biotype) and Group II (implants were placed in thin tissue biotype). Baseline cone-beam computed tomography (CBCT) was performed after implant placement in both groups, and follow-up CBCT was taken at the time of cementation prior to occlusal loading to assess the crestal bone loss around the mesial and distal side of implants in both groups.

Awareness of forensic dentistry among dental professionals in western Saudi Arabia: A knowledge, attitude, and practice-based cross-sectional study.

The aim of the study is to assess the knowledge, attitude, practice, and self-reported record for a list of items that are useful to forensic dentistry (FD) among dental professionals from the western region of Saudi Arabia. This cross-sectional survey was conducted among 406 dental health professionals. A pre-validated questionnaire written in Google Forms was used as a study tool.

Optical penetration models for practical prediction of femtosecond laser ablation of dental hard tissue.

Objectives: To develop and practically test high-precision femtosecond laser ablation models for dental hard tissue that are useful for detailed planning of automated laser dental restorative treatment.

Methods: Analytical models are proposed, derived, and demonstrated for practical calculation of ablation rates, ablation efficiency and ablated morphology of human dental enamel and dentin using femtosecond lasers. The models assume an effective optical attenuation coefficient for the irradiated material.

Are we gaining valid consent for dental extractions? A retrospective audit on restorability assessment at one dental institution.

Introduction This paper explores the widely relevant topic of obtaining valid consent in dental practice, focusing on assessing restorability of teeth planned for extraction. The General Dental Council stresses discussing treatment options, benefits and risks for informed decision-making. The study evaluates if pertinent factors, including tooth structure, endodontic status, periodontal health and patient considerations, are considered before consent.

Minimum intervention oral care - incentivising preventive management of high-needs/high caries-risk patients using phased courses of treatment.

This paper demonstrates how person-focused, prevention-based, risk/needs-related, team-delivered, minimum intervention oral care (MIOC) principles and approaches can be integrated into the dental profession for the delivery of environmentally sustainable, optimal care to high-needs and high caries-risk/susceptibility patients. It highlights the potential for NHS remuneration for prevention-based, phased, personalised care pathways/plans (PCPs) within a reformed NHS dental contract system. It emphasises the importance of comprehensive and longitudinal patient risk/susceptibility assessments, prevention and stabilisation of the oral environment before considering more complex, definitive restorative work.
