Evaluating the Patterns of Impaction in Lower Third Molars and Associated Radiolucent Lesions: An Observational Cross-sectional Study.

Aim: The aim of this study was to evaluate radiolucent lesions associated with impacted lower third molars, focusing on their pathological diagnosis and the distribution of sex and age among the affected individuals.

Materials And Methods: This retrospective cross-sectional study was conducted at King Khalid Dental University Hospital, Riyadh, Saudi Arabia, between January 2020 and August 2023. A total of 312 orthopantomography (OPGs) records were examined, covering 549 teeth.

Extranodal Anaplastic Large Cell Lymphoma Involving the Pancreas: A Rare Presentation.

Anaplastic large-cell lymphoma (ALCL) is a subtype of T-cell lymphoma. This disease mainly affects lymph nodes, although extranodal sites may also be involved. Lymphoma in the pancreas is a rare clinical entity whether it manifests as primary or extranodal involvement.

Comparison of Enamel Surface Integrity after De-Bracketing as Affected by Seven Different Orthodontic Residual Cement Removal Systems.

This study used seven different adhesive removal systems to evaluate and compare enamel surface integrity, heat generation, and time consumed during residual cement removal after de-bracketing. The sample size was 140 human premolars. Teeth were cleaned, mounted, and prepared for orthodontic bracket bonding.

Brimonidine.

Brimonidine is a highly selective 2-adrenoceptor agonist that lowers intraocular pressure (IOP) by decreasing aqueous humor production and increasing aqueous humor outflow via the uveoscleral route. Brimonidine is used to treat glaucoma and other eye conditions. Brimonidine is a topical medication that is used mainly to treat open-angle glaucoma and ocular hypertension in the eyelids.

Profiling of circRNA expressions in radiation-treated head and neck cancer cells and the potential role of circPVT1.

Objective: Radiotherapy is an indispensable treatment modality for head and neck cancers (HNCs). Due to their stable structure, circular RNAs (circRNA) have been implicated as potential biomarkers for clinical use in cancers. The purpose of this study was profiling the circRNA in radiation-treated head and neck cancer cells to identify potential differentially expressed circRNAs.

Factors related to COVID-19 vaccine hesitancy in Saudi Arabia.

Objectives: To assess the amount of vaccine hesitancy and its determinants in relation to various demographic, social, and personal characteristics among the Saudi population.

Study Design: Cross-sectional study.

Methods: we utilized a structured questionnaire on a five point-Likert scale that included immunization process awareness, perception towards immunization and factors leading to vaccine refusal.

Spontaneous Eruption of a Deeply Impacted Premolar After Conservative Treatment of an Associated Dentigerous Cyst: A Case Report.

Dentigerous cysts are benign odontogenic cysts that develop around the crowns of permanent teeth and are considered rare in children. This article reports a case of a 10-year-old girl with an inflammatory dentigerous cyst associated with the right mandibular premolar and deeply displacing it to the lower border of the mandible. To preserve the developing mandibular premolar and the mental nerve, marsupialization of the lesion under local anesthesia was performed.

Maximum mouth opening and its correlation with gender, age, height, weight, body mass index, and temporomandibular joint disorders in a Saudi population.

: To investigate maximum mouth opening (MMO) and its correlation with gender, age, height, weight, Body Mass Index, and temporomandibular joint disorders in a Saudi population.: This is an observational cross-sectional study of 222 Saudi patients (46% male and 54% female). Patients were clinically examined, and files were accessed to record data.

Prevalence of type 1 diabetes mellitus in Saudi Arabian children and adolescents.

Objective: To determine the prevalence of type 1 diabetes mellitus among 0-19 years old Saudi children and adolescents.

Methods: A nationwide Saudi Arabian project was conducted in the years 2001-2007 with the objective of establishing national growth charts, and defining the prevalence of some chronic childhood diseases such as diabetes mellitus. The 14,000 households were randomly selected based on a recent population statistic.

Voluntary activation failure is detectable in some myositis patients with persisting quadriceps femoris weakness: an observational study.

This cross-sectional, observational study was undertaken to examine whether voluntary activation failure could contribute to the persisting weakness observed in some patients with treated idiopathic inflammatory myositis. In 20 patients with myositis of more than six months' duration (5 males, 15 females; mean [+/- 1 SD] age 53 11 years) and 102 normal subjects (44 males, 58 females; mean age 32 8 years), isometric maximum voluntary contractions (MVCs) of the dominant quadriceps femoris (QF) were quantified. Absolute MVC results of normal subjects and patients were then normalised with respect to lean body mass (force per units of lean body mass), giving a result in Newtons per kilogram.
