Effect of Hyaluronic Acid on Socket Healing After Lower Impacted Third Molar Tooth Extraction in 40 Dental Patients.

BACKGROUND Surgical extraction of impacted mandibular third molars is the most commonly performed procedure in oral surgery; its associated complications include sensory nerve damage, swelling, and trismus. This study aimed to evaluate the effects of hyaluronic acid (HA) on healing of the socket following extraction of the lower impacted third molar tooth in 40 dental patients. MATERIAL AND METHODS This prospective, double-blind, randomized, controlled study was carried out on 40 adult healthy patients indicated for surgical removal of bilateral impacted mandibular third molars with equal surgical difficulty (moderate surgical difficulty according to the Koerner index.

Denoised encoder-based residual U-net for precise teeth image segmentation and damage prediction on panoramic radiographs.

Objectives: This research focuses on performing teeth segmentation with panoramic radiograph images using a denoised encoder-based residual U-Net model, which enhances segmentation techniques and has the capacity to adapt to predictions with different and new data in the dataset, making the proposed model more robust and assisting in the accurate identification of damages in individual teeth.

Methods: The effective segmentation starts with pre-processing the Tufts dataset to resize images to avoid computational complexities. Subsequently, the prediction of the defect in teeth is performed with the denoised encoder block in the residual U-Net model, in which a modified identity block is provided in the encoder section for finer segmentation on specific regions in images, and features are identified optimally.

Incorporation of Zirconium Oxide Nanoparticles in Adhesive Resin for Bonding of Brackets to Enamel Conditioned with Er,Cr:YSGG, Photodynamic Therapy, and Phosphoric Acid.

To evaluate the effect of enamel conditioning methods, that is, total-etch and rinse (TER), Er,Cr:YSGG (ECYL), and photodynamic therapy (PDT) on the shear bond strength (SBS) of orthodontic metallic brackets bonded using Zirconium oxide experimental adhesive (ZOEA). Sixty human incisor buccal surfaces were cleaned and allocated into three groups based on the method of enamel surface treatment, that is, TER using 37% phosphoric acid gel, methylene blue photosensitizer activated by PDT and ECYL ( = 20 each). Each group was further divided into two subgroups ( = 10) based on the type of adhesive, that is, ZOEA and experimental adhesive (EA).

Three-Dimensional FEA Analysis of the Stress Distribution on Titanium and Graphene Frameworks Supported by 3 or 6-Implant Models.

Titanium is the main component of dental implants. It is also routinely used as a framework material for implant-supported full-arch prostheses due to its low density, biocompatibility, and other mechanical properties. Remarkable mechanical properties such as lesser mass density and higher young's modulus of graphene have gained popularity among scientists, improving the properties of biomedical implants.

Temporomandibular Joint Space Dimensions among Saudi Patients with Temporomandibular Disorders: MRI-Based Retrospective Study.

Introduction: The temporomandibular joint is a complex synovial joint in the body. It is the area in which the mandible articulates with the cranium. The temporomandibular joint space is located between the articular eminence and the glenoid fossa of the temporal bone at the base of the skull and the condylar process of the mandible.

The need for socket preservation: a systematic review.

The aim of this study was to evaluate the clinical need and impact of socket preservation to protect the bone for future dental implant placement. Moreover, we aimed to list down various methods of socket preservation by going through randomized clinical trials. We searched PubMed, Google Scholar, and Cochrane databases for all relevant publications, where researchers compared various methods and tools for socket preservation.

Distraction Osteogenesis of Severely Resorbed Mandible.

Edentulous patients require an adequate rehabilitation so that the alveolar ridge in the interforaminal region be restored for subsequent implant-supported overdentures. The ultimate goal of distraction is to reconstruct the alveolar ridge to a suitable height and width compatible with Atwood class 2 in an appropriate direction allowing the sagittal interalveolar relation to be normally restored. .

Knowledge and Awareness of Postextraction Complications among Dental Seniors and Interns in Riyadh Province.

Background: Postextraction complications are multifactorial. Taking proper medical and dental history, thorough planning, and a skillful dentist can help the prediction and reduction of these complications.

Objective: This study aims to assess and compare the knowledge of senior students and interns regarding postextraction complications in government and private colleges in Riyadh Province.

Efficacy of Antibiotic Versus Probiotics As Adjuncts to Mechanical Debridement for the Treatment of Peri-Implant Mucositis.

The objective was to compare the efficiency of probiotic therapy (PT) vs antibiotic therapy (AT) as adjuvants to nonsurgical-mechanical debridement (NSMD) for the treatment of peri-implant mucositis (Pi-M). Volunteers with Pi-M were encompassed. Therapeutically, patients were randomly divided into 3 groups: (a) Group 1: NSMD + PT; (b) Group 2: NSMD + AT; and (c) Group 3: NSMD alone.

Role of Probiotics for the Treatment of Peri-Implant Mucositis in Patients With and Without Type 2 Diabetes Mellitus.

This study hypothesized that probiotic therapy (PT) does not offer additional benefits to mechanical debridement (MD) for the treatment of diabetic subjects with peri-implant mucositis (PM). This study compared the influence of PT as an adjunct to MD for the treatment of PM in type 2 diabetic and nondiabetic patients over a 12-month follow-up period. Patients with and without type 2 diabetes were included.

Relationship between buccal alveolar bone thickness and crown-to-root dimensions around mandibular first and second molars: A cone-beam-computed tomography-based study.

Background: Assessment of buccal alveolar bone thickness (ABT) and crown-to-root dimensions are essential in implant density; therefore, three-dimensional evaluation of these parameters provides a superior visualization than conventional radiographs.

Objective: The present cross-sectional cohort study aims to investigate the relationship between buccal ABT and crown-to-root dimensions around the mandibular first and second molars using cone-beam-computed tomography (CBCT).

Methods: Initially, CBCT-based scans from 271 individuals were assessed.

Knowledge, Attitude, and Management of General Dentist toward Medication-related Osteonecrosis of the Jaws.

Background: Medication-related osteonecrosis of the jaw (MRONJ) is an intense negative drug response causing increasing bone destruction in the maxillofacial area of patients.

Aims And Objectives: To evaluate the knowledge and attitude of dental practitioner regarding risk factors of MRONJ in Saudi Arabia.

Materials And Methods: A cross-sectional, questionnaire survey was carried out in King Khalid Hospital, Al-Kharj among dental practioners.
