Would Access Cavity Design Affect The Mechanical Behaviour Of Tooth : A Finite Element Study., Muhammad Ashraf Elhusseini, Engy Kataia, Hala Khalil

International Arab Journal of Dentistry

Two distinct access cavity designs were used to access Two simulated finite element models (FE). (Lingual (LAC) and incisal (IAC)). Three experimental FE models, including the IT model, were developed: LAC and IAC. For every simulated model, one distinct radicular preparations was carried out of size #30/.04. The incisal edge was subjected to an occlusal cycle load of 120 N. The maximum von mises stresses (VMS), maximum principal stresses (MPS), and stress distribution patterns were assessed and calculated quantitatively. It was concluded that the mandibular incisor's biomechanical behavior is significantly influenced by the size of the access design. Biomechanically the …

Comparative Evaluation Of Efficacy Of Topical Ozonated Olive Oil And Topical Chlorhexidine Gluconate In Management Of Recurrent Aphthous Stomatitis., Prasanna Ravindra Sonar, Aarati Panchbhai, Anil Ghom, Sudhir Dole

International Arab Journal of Dentistry

Aphthous stomatitis is also known as canker sores or aphthae. Recurrent aphthous stomatitis (RAS), frequently manifests as superficial, oval, painful ulcers with a pseudomembranous base that is yellowish-gray and has an erythematous halo [1-2]. These uncomfortable lesions may have a significant impact on dental hygiene, speech, and eating. Hence, the lesions may have an even greater influence on living quality than only the discomfort they cause [3-5]. Even though the lesion normally heals on its own, the pain from the aphthae causes severe morbidity.

This disease entity is caused by multifactorial etiologies, which include inherited, environmental, infections caused by various …
