PURPOSE: This research aimed to describe the stress distribution of an endodontically treated tooth with a mesio-occluso-distal (MOD) cavity restored with direct composite reinforced with polyethylene and e-glass ribbon fiber. METHODS: This research was a descriptive study using the finite element method. A 3D model of the mandibular first molar solid after endodontic treatment with class II MOD preparation was prepared using Solidworks software. Finite element simulation was carried out using Abaqus software...

INTRODUCTION: Endodontically treated teeth (ETT) undergo extensive structure change and experience high stress during biomechanical function. Stress distribution is influenced by the restoration material and the type of bond between material and tooth structure. The selection of materials that can distribute stress will affect the resistance and retention of ETT to mastication forces, thus biomechanical functions were achieved. Composite has mechanical properties similar to dentin, it can transmit and distribute stresses throughout the tooth surface...

PURPOSE: This study aimed to determine the intention of older adults to use silver diamine fluoride (SDF) for treating tooth decay. PATIENTS AND METHODS: A group of Thai-speaking individuals between the ages of 60 and 90 were asked to participate in the study. They were provided with information about SDF and then asked to complete a questionnaire based on the Theory of Reason Action (TRA). The questionnaire consisted of 23 questions divided into seven constructs aimed at determining the determinants of the intention to use SDF...

BACKGROUND: Findings show that periodontitis does not affect all populations; similarly, some individuals present risk conditions such as occupational stress, making them more susceptible to developing periodontitis through unhealthy habits like poor oral hygiene and immune suppression. Periodontitis triggers an inflammatory host immune response; "Receptor Activator Nuclear Factor KB ligand (RANKL)" is the primary regulator of osteoclast differentiation and activity. It was found that osteoclastic bone damage caused by periodontitis depends on the RANKL produced by osteoblastic and periodontal ligament cells...

PURPOSE: Compression necrosis refers to bone tissue damage that can occur when excessive pressure or force is applied to surrounding bone during implant placement. This pressure can compromise blood supply to the bone, leading to necrosis. Compression necrosis is a concern, because it can affect the stability and long-term success of dental implant. PATIENTS AND METHODS: This case report highlights a case of early bone loss and implant failure possibly due to compression necrosis...

BACKGROUND: Oral health is crucial for overall well-being and systemic health and Humans are exposed to several bacteria after birth and will causes systemic illnesses like septicemia, respiratory, gastrointestinal, and renal issues. This study aimed to evaluate undergraduate students' knowledge, attitudes, and practices regarding toothbrush contamination and disinfection. METHODS: A descriptive cross-sectional study was carried out with undergraduates from seven selected universities, including public and private universities...

PURPOSE: The long-term success of any organization is highly dependent on client satisfaction. This applies to the medical and dental fields, where patient satisfaction is considered an indirect indicator of the quality of service provided. This study aimed to assess the level of satisfaction of patients treated by final-year undergraduate students at King Abdulaziz University Dental Hospital (KAUDH). PATIENTS AND METHODS: In this cross-sectional study, an online questionnaire was distributed to patients (aged ≥14 years) treated at KAUDH by sixth year students during the academic year 2020/2021...

OBJECTIVE: The aim of this survey was to investigate the main reasons for extraction of permanent teeth, and its correlation with age, gender, education level, smoking habits, and time of last dental visit, family income, and professions in Kabul, Afghanistan. SUBJECTS AND METHODS: The study proposal was approved by Research Ethics Committee of Khatam AL Nabieen and was conducted over a period of 5 months; its population consisted 594 patients, aged 10-70 years, who underwent extraction...

BACKGROUND: This simulated study of 30 severely curved L-shaped root canals aimed to compare preparation time, aberrations, width measurements, and fractured files of three nickel-titanium (Ni-Ti) files, namely, ProTaper, ProTaper Next (PTN), and WaveOne (WO). METHODS: Thirty simulated L-curved root canals of resin blocks were randomly divided into three groups. The canals were prepared to a tip size of 25 using ProTaper, PTN, and WO rotary file systems. Pre- and post-operative views for each sample were captured by a professional camera at a standardized distance and position...

BACKGROUND: Several factors are associated with coronal and root caries in older persons. The purpose of this study was to determine the experience, prevalence, and risk indicators (socioeconomic, sociodemographic, and dental variables) of coronal and root caries in older persons residing in nursing homes in Mexico. METHODS: A cross-sectional study was carried out in 227 dentate participants with natural teeth. Convenience sample, where all dentate residents were invited to participate...

BACKGROUND: Numerous investigations have revealed that oral issues are quite common among young Afghans. Knowledge, attitudes, and behavior are the three oral health-related population dimensions that need to be assessed in order to design effective public health awareness programs. OBJECTIVE: The study's goal was to find out how much health professions' students at Kabul University of Medical Sciences knew about oral health, as well as their attitudes and behaviors toward dental health and oral hygiene routines...

PURPOSE: Studies show that Teledentistry helps enhance communication between dental peers and patients and improves time management and education. The knowledge and awareness of Teledentistry levels need to be measured for a wider adaption. This study aimed to explore the knowledge and awareness of Teledentistry among dental practitioners and patients who live in Jeddah City, Saudi Arabia. PATIENTS AND METHODS: This study is a descriptive cross-sectional study with two participant groups...

BACKGROUND: Numerous genetic variations in inflammasome components are linked to prevalent disorders in the general population, including periodontitis and cardiovascular illness. Polymorphisms in the genes play a critical in the initiation and development of inflammatory diseases. The limited study on AIM2 gene variation associated with inflammatory disease and no study of PYCARD gene variation associated with inflammatory disease. OBJECTIVE: This case-control study was to examine the association between the single nucleotide polymorphism of AIM2 and Pycard genes with susceptibility to periodontitis with and without coronary heart disease, to determine interleuken-18 and gasdermin D levels in the saliva of periodontitis with and without coronary heart disease patients, as well as their correlation with salivary interleuken-18 and gasdermin D levels and clinical periodontal parameters...

BACKGROUND: The symmetry between maxillary anterior teeth and the face holds significant importance. This study assessed and analyzed the relationship between facial parameters and anterior teeth in the maxillary arch of male and female subjects. Specifically, individual width and combined width (CW) measurements of the maxillary anterior teeth were investigated. METHODS: This study involved a total of 150 dentate Yemeni subjects (74 men and 76 women), whose ages ranged from 18 years old to 30 years old...

INTRODUCTION: Matrix metalloproteinases enzymes (MMPs) can degrade the hybrid layer which can cause failure of composite restorations. Chlorhexidine gluconate 2% can reduce MMPs activity and increase the bond strength of the resin to dentin. PURPOSE: This study aims to determine the role of the duration of chlorhexidine gluconate 2% application on shear bond strength of a total-etch bonding agent. METHODS: A total of 36 freshly extracted maxillary premolars were removed occlusally by one-third of the crown using a carborundum disc until the dentin was exposed...
