Stability and Success of Clear Aligners in Orthodontics: A Narrative Review.

The implementation of Clear Aligner Therapy (CAT) in adult orthodontics exemplifies the integration of advanced technology in the dental healthcare sector. Representing a significant shift in modern orthodontics, CAT offers a convenient and aesthetic alternative to traditional fixed appliance treatments for mal-aligned dentition. This narrative review aims to explore the applicability of CAT, delineating its biomechanics, indications, contraindications, scope, limitations, and factors influencing long-term stability and successful outcomes.

Myofascial Pain Syndrome and Its Relation to Trigger Points, Facial Form, Muscular Hypertrophy, Deflection, Joint Loading, Body Mass Index, Age and Educational Status.

Introduction: Myofascial pain (MFP) is a type of pain characterized by the presence of a trigger point (TrPs) in taut band of skeletal muscles or its fascia. Based on the current literature, the prevalence of head and neck myofascial pain (HNMFP) varies among different communities. To better understand this condition and its relation to facial form, muscular hypertrophy, deflection, and joint loading, the study aimed at evaluating the prevalence of HNMFP among the population of Jeddah, Saudi Arabia.

A successful management of sever gummy smile using gingivectomy and botulinum toxin injection: A case report.

Introduction: A gummy smile (GS) affects the esthetic and the psychological status as it usually decreases the self-confidence leading to hidden or controlling the smile. A smile with more than 2 mm exposed gingiva is called gummy smile. It may be due to one or more of the following etiologies; altered passive eruption of teeth, dentoalveolar extrusion, vertical maxillary excess, and short or hyperactive lip muscles.

Oral manifestations of a rare variant of Marfan syndrome.

This article reports the oral manifestations of an unusual presentation of Marfan syndrome (MFS) and provides an evidence to the importance of recognizing the oral features in confirming the diagnosis of MFS. Dentists have a vital role in confirming the diagnosis of developmental disorders that involve the craniofacial compendium.

Effect of clasp type and pullout location on clasp retention in different environment: study.

Objective: The purpose of this study was to investigate the importance of pullout location and clasp types in two different environments to dislodge the clasp.

Materials And Methods: Mandibular test models with natural premolars and molar teeth were used to test four types of clasp (each 12) (Akers, Rest plate Akers, Half and Half, and Ring clasp) with three different pullout location for each type (ring on the rest, loop on the saddle, and wax arising from both rests) in dry and natural fresh saliva environment. Each clasp was pulled out 10 times with a crosshead speed of 10 mm/min, and the force required to withdraw each was measured.

Thalassemia review: features, dental considerations and management.

Thalassemia is a genetic disorder that involves abnormal haemoglobin formation. The two main categories of thalassemia are alpha and beta thalassemia that are then divided into further subcategories. While some mild forms of thalassemia might even go unnoticed and only cause mild anaemia and iron deficiency problems in patients, other more severe forms of thalassemia can even result in death.

Methods: Tissue sections from left atrial appendage of the heart were carefully dissected from seventy five patients underwent conventional coronary artery bypass grafting at the cardiothoracic surgical department, Manchester Royal Infirmary. Tissue was fixed, sectioned, stained and six random sections were photographed and the images were assessed and quantified using Image Analyser Pro-Plus software, version 4.

Cone Beam Computed Tomography Analysis of Upper Airway Measurements in Patients With Obstructive Sleep Apnea.

Purpose: To explore the validity of cone beam computed tomography (CBCT) as one of many predictive tools that can be used (alone or in conjunction) to help in identifying high-risk cases of obstructive sleep apnea (OSA) that should get the earliest possible referral to a sleep specialist for standard diagnostic polysomnography, and to identify imaging airway parameters that may be predictive of OSA severity.

Methods: Using a case-control design, 45 subjects matched by age and sex (22 OSA cases and 23 controls) were included in this study. Subjects were assigned as cases depending on a sleep study with apnea-hypopnea index (AHI)>5 and as controls depending on a Berlin questionnaire score identifying low risk or no risk of OSA.
