Effect of resin cement viscosities and surface roughness on shear bond strength of conditioned polymer infiltrated ceramic network.

Background: Hybrid ceramics bonding with the dentinal substrate is crucial for clinical success and longevity. To enhance adhesion, the surface of ceramic restorations is modified through various conditioning techniques AIM: Effect of Different Surface Conditioners Erbium-doped yttrium aluminum garnet (ER: YAG) laser and Low-level laser therapy (LLLT) activated Methylene blue (MB) on the surface roughness (Ra) and shear bond strength (SBS) of Polymer infiltrating ceramic network (PICN) discs bonded using different viscosity resin cement before and after thermal aging.

Material And Methods: One hundred and fifty human central incisors and one hundred and fifty-three PICN discs were prepared.

Knowledge, awareness, and attitude among dental students regarding oral cancer in Saudi Arabia.

Background: Oral cancer awareness among junior and seniors' dental undergraduate students may have an impact on the early detection and prevention of oral cancer.

Aims And Objectives: To assess oral cancer awareness, knowledge and attitude among undergraduate dental students in government and private colleges in Saudi Arabia.

Material And Methods: A cross-sectional survey was undertaken to assess oral cancer knowledge, awareness and attitude among undergraduate dental students in government and private colleges in Saudi Arabia.

Determinants of COVID-19 Vaccine Acceptance among Dental Professionals: A Multi-Country Survey.

Purpose: This study sought to investigate the acceptance rate and associated factors of COVID-19 vaccines among dentists and dental students in seven countries.

Material And Methods: A structured questionnaire prepared and guided by the report of the SAGE Working Group on Vaccine Hesitancy was distributed among groups of dentists and dental students in seven countries across four continents.

Results: A total of 1527 subjects (850 dentists and 677 dental students) participated in this survey.

Dentists' Perception of Oral Potentially Malignant Disorders.

Objectives: Dentists play a major role in the diagnosis of oral potentially malignant disorders (OPMDs) that may lead to malignancy. Their knowledge on OPMDs and the risk factors associated with malignant disease needs to be sufficient. The aim of this study was to assess the level of knowledge, attitudes, and awareness of OPMDs amongst general dentists and dental specialists working in Saudi Arabia.

Pemphigus Vulgaris in Old Patient.

Pemphigus vulgaris (PV) is a chronic, autoimmune, intraepidermal blistering disease of the skin and mucous membranes. The first clinical manifestation is often the development of intraoral lesions, and later, the lesions involve the other mucous membranes and skin. The etiological factors of this disease still remain unknown, although the presence of autoantibodies is consistent with an autoimmune disease.

Efficacy of porphyrin derivative, Chlorhexidine and PDT in the surface disinfection and roughness of Cobalt chromium alloy removable partial dentures.

Aim: The present study aimed to evaluate the effect of different cleansers and photodynamic therapy (PDT) on disinfection of Co/Cr removable partial denture colonized with C. albicans, S.aureus and S.

In vitro Analysis of Shear Bond Strength and Adhesive Remnant Index of Stainless Steel Brackets with Different Adhesive Systems to Enamel.

Aim: This study aimed at evaluating and comparing the bond strength of stainless steel brackets bonded with multiple orthodontic adhesives.

Materials And Methods: About 60 premolars extracted to create space during orthodontic treatment were included in the present study. Premolar stainless steel brackets of size 0.

Early Childhood Caries: A Review.

Aim: To review and update the current knowledge about early childhood caries (ECC) and its etiology, prevalence, risk factors, management, and preventive strategies.

Background: Early childhood caries is a disease affecting significantly both well-developed and industrial nations. The ECC can significantly affect the child's quality of life, as it may lead to infection, swelling, pain, and other symptoms.

Therapeutic potential of dental stem cells.

Stem cell biology has become an important field in regenerative medicine and tissue engineering therapy since the discovery and characterization of mesenchymal stem cells. Stem cell populations have also been isolated from human dental tissues, including dental pulp stem cells, stem cells from human exfoliated deciduous teeth, stem cells from apical papilla, dental follicle progenitor cells, and periodontal ligament stem cells. Dental stem cells are relatively easily obtainable and exhibit high plasticity and multipotential capabilities.

Orthopedic Effect of Chin Cup during Mixed Dentition Stage.

Introduction: Chin cup (CC) therapy has been used as the traditional appliance for treating class III malocclusion during mixed dentition period. The aim of this study was to investigate the effect of CC on the improvement of skeletal and dentoalveo-lar skeletal changes in class III patients during mixed dentition stage.

Materials And Methods: A total of 30 patients (7-9 years old) with skeletal class III malocclusion were selected based on clinical and cephalometric examination.

Early Orthognathic Surgery: A Review.

Management of growing patients with severe developmental jaw abnormalities can be very difficult. Early surgical intervention may be warranted in situations where function (e.g.

A comparative study of the bone contact to zirconium and titanium implants after 8 weeks of implantation in rabbit femoral condyles.

Zirconium (Zr) has been found to have comparable characteristics to titanium with a favorable modulus of elasticity. In addition, the release of Zr-ions of a Zr implant is supposed to further increase the bone-to-implant response. Therefore, the objective of this study is to compare the bone contact to Zr and Ti implants in the femoral trabecular bone of rabbits.

Comparative Study of Piezoelectric and Rotary Osteotomy Technique for Third Molar Impaction.

Introduction: Bone removal is necessary for extracting the third molars that are erupted, partially erupted, and/or impacted in bone. Hence, it is necessary to choose a surgical method or instruments that conform to anatomic landmarks and are based on physiological principles. Many authors have reported injuries to the adjacent tooth, especially the distal part of periodontium after removal of second molar.

Intricate Evaluation of Association between Dental Caries and Obesity among the Children in Al-Kharj City (Saudi Arabia).

Introduction: Dental caries and obesity are two of the most prevalent health conditions affecting children. Relative decrease in corporeal movements, escalating inactive lifestyles, and changes in dietary factors are strongly linked with the increasing incidence of overweight and obesity. Furthermore, obesity increases the risk of chronic disease and dental caries that significantly affects the quality of life of young children.
