In our study, the structural and morphological applications of hydroxyapatite and chitosan nanoparticles and coated micro-implants were assessed for their ability to combat oral pathogenic bacteria. The hydroxyapatite, as well as chitosan nanoparticles, were synthesized from the Salvadora persica plant. The crystal morphology, phase composition, pa...

Introduction: Angle's classification is the most widely used instrument for evaluation of malocclusion. The dental esthetic index (DAI) is a reliable, valid, and universally accepted cross-cultural index adopted by the World Health Organization (WHO) that links objective, clinical, and subjective esthetic factors to produce a single score that ref...

Background: In spite of the fact that fashion braces (FBs) have been in the spotlight in recent years among both orthodontists and the general public in several countries, there is still limited evidence regarding FBs. The aim was to identify health-related behaviors in using FBs by considering the Health Belief Model (HBM). Methods: A cross-sec...

Objectives To examine the correlation between spheno-occipital synchondrosis fusion stages and the hand-wrist skeletal maturity index. Materials and Methods Digital records of 164 individuals (77 males, 87 females) aged 10 to 18 years old were examined. Three-dimensional CBCT scans and hand-wrist two-dimensional radiographs were scored for the sph...

Background Oral cancer requires early diagnosis and treatment to increase the chances of survival. This study aimed to develop an artificial neural network model that helps to predict the individuals' risk of developing oral cancer based on data on risk factors, systematic medical condition, and clinic‐pathological features. Methods A popular data...

Oral cancer, a universal malady, has become a stumbling block over the years due to its significant morbidity and mortality rates. The greater morbidity associated with this deadly disease is attributed to delay in its diagnosis / its presentation in advanced stage. Being multifactorial, Oral squamous cell carcinoma (OSCC) is the outcome of genetic...

Background: Case-based learning (CBL), in contrast to traditional lecture-based learning (LBL), is an andragogical method carrying an earnest teaching approach that uses demonstration of clinical cases as an active learning tool. Objective: To compare the effectiveness of knowledge delivery and student satisfaction between CBL and LBL strategies...

Objectives: The applied orthodontic force causes remodeling of the periodontium through the selective release of cytokines causing resorption of bone, enabling controlled movement of the tooth. This study compared the cytokine profile between patients treated with conventional labial and lingual fixed orthodontic appliances. Patients and Methods: T...

Objective To provide information on the prevalence and clinical features of impacted third molar teeth in the South-Western region of Saudi Arabia. Material and methods In this cross-sectional study, 1200 panoramic radiographs (50% males and 50% females) were retrieved from the electronic clinical records of patients at the College of Dentistry, J...

Aim: Evaluating the association of maxillary sinus dimensions and the maxillary arch dimensions may help to understand the interrelationship between the maxillary sinus and the anatomical facial features. The study aimed to investigate the correlation of the 2-D and 3-D maxillary sinus dimensions with the linear measurement of the maxillary arch w...

Introduction: The design of the orthodontic bracket or appliance is 1 of the most important factors for creating retentive areas for biofilm formation. In orthodontics, this would be the first study to compare the microbial level changes in 3 different types of orthodontic appliances using checkerboard DNA-DNA hybridization technique. The purpose...

Objective: To test the hypothesis that the levels of IL-1ß and TNF-α increased more and IL-1α, IL-2, IL-6, IL-8 increased less, after 3 weeks of treatment with conventional labial fixed appliance and with aligners. Material and methods: Forty patients who were treated either with labial brackets (n = 20) or aligners (n = 20). Gingival crevicular fl...

Objectives This study examines the relationship between spheno-occipital synchondrosis (SOS) closure and puberty onset in a modern American population. It also investigates the timing and the rate of SOS closure in males and females. Materials and methods The sample includes cross-sectional and longitudinal 3D Cone Beam Computed Tomography (CBCT)...

Objective:The purpose of this pilot study was to analyze the closure pattern of the spheno-occipital synchondrosis for sample of 15 subjects and correlate it with cervical vertebral maturation to assess if this biologic marker is a useful tool to be used in assessment of skeletal maturation. Method:The sample consisted of 15 individuals in the ag...
