Background: Malocclusion and lifestyle diseases like obesity can lead to poor oral hygiene and food stagnation, resulting in increased caries incidence.
Objectives: To evaluate the interrelationship of age, body mass index (BMI), occlusion, and dental decay in children aged between 5 and 14.
Methodology: Our study included 423 school students aged 5-14 visiting dental clinics.
Article Synopsis
- The study explores the perception, interest, and barriers to practicing yoga among residents of Saudi Arabia, focusing on their stress levels.
- Conducted with 906 participants, mostly non-Saudi women aged 31-51, it found that many were aware of yoga's benefits but varied in their practice based on stress levels.
- The results suggest a connection between stress and yoga awareness and participation, highlighting the need for more in-depth research on the topic.
Effect of adding sodium fluoride and nano-hydroxyapatite nanoparticles to the universal adhesive on bond strength and microleakage on caries-affected primary molars.

Article Synopsis
- - The study evaluated the effectiveness of sodium fluoride (NaF) and nano-hydroxyapatite (n-HA) modified universal adhesives on the bond strength and leakage in carious primary molars, using both etch-and-rinse (ER) and self-etch (SE) techniques.
- - A total of 120 primary molars were grouped and tested, with the results showing that SE bonding led to highest leakage and lowest bond strength, while n-HA with ER provided the best outcomes in terms of minimal leakage and maximum bond strength.
- - The comparison indicated that NaF and n-HA modified adhesives performed similarly well for bonding to carious dentin, showing promising results for dental health and restoration longevity.
Modified Hybrid Hydroxyapatite-Silver Nanoparticles Activated via a Blue Light Source in Various Concentrations in Two-Step Self-Etch Adhesive to Caries-Affected Primary Dentin.

Article Synopsis
- This study investigates the effectiveness of hydroxyapatite-silver (HA-Ag) hybrid nanoparticles as an antibacterial agent in self-etch adhesives for dental applications, particularly in treating primary molar teeth with carious lesions.* -
- A total of 80 primary molars were divided into four groups based on the concentration of HA-Ag nanoparticles used—0%, 1%, 5%, and 10%—and their effects on microtensile bond strength (μTBS), antibacterial efficacy, and degree of conversion (DC) were assessed.* -
- Results showed that 1% HA-Ag nanoparticles provided the best balance of antibacterial properties, bond strength, and degree of conversion, while the 10% concentration
Systemic lupus erythematosus (SLE) with oral desquamative lesions is one of the rare clinical entities. Periodontal disease and SLE display various mechanisms and possess a wide range of pathological characteristics. The tissue destruction mechanism of periodontitis and autoimmune diseases share similar pathways, and mounting reports studied the association between these two entities.

Given that periodontal diseases have been linked to respiratory illnesses like pneumonia, it is quite possible that periodontitis and COVID-19 are related. Therefore, the purpose of the current study was to ascertain whether the severity of COVID-19 and periodontal disease are related.

Aim: To compare the knowledge regarding HPV, its association with OPC, and HPV vaccine among students from different countries, years of the undergraduate program, and gender.
Methods: The current multinational cross-sectional study was conducted in 886 undergraduate dental students from Egypt, India, Pakistan, Saudi Arabia, UAE, and Sudan through Google survey forms from July 2021 to September 2021.
Aim: The aim of this study was to assess the perception, knowledge, and attitude of individuals from different regions of Saudi Arabia toward dental implants and bone grafts.
Material And Methods: An online, self-oriented, and cross-sectional-based questionnaire with 21 items was given to 1622 individuals from different regions of Saudi Arabia. The questionnaire recorded the perception, knowledge, and attitude of participants and their agreement or rejection of dental implants and various kinds of bone grafts.
