Different degrees of clinical success have been reported for synthetic, allograft, and xenograft bone substitutes in human trials. Although these clinically investigated, their vitro effects on cell differentiation remain unclear. Proliferation, differentiation, attachment dental pulp stem cells (DPSCs) to β-tricalcium phosphate (β-TCP), freeze-dried allograft (FDBA), deproteinized bovine mineral (DBBM) were compared this study. MTT assay, measurement total DNA, reverse transcriptase...

Neurofibroma (NF) is a benign peripheral nerve sheath tumor which consists of Schwann cells, perineurial‐like and fibroblasts. The NF can be central or peripheral, alone multiple manifestation Type I neurofibromatosis. NFs are mostly found in the tongue, oral mucosa, lips when appearing mouth cavity, but they rare at palate solitary form. We report case originating hard 30‐year‐old woman. patient had an asymptomatic, nonulcerated, sessile, pink, smooth nodule measuring 15 × 25 5 mm with firm...

Preoperative anxiety is the subject of major concern for many patients.The current study aimed at determining effect anesthesia consultation on decreasing in patients undergoing oral and maxillofacial surgery.This randomized clinical trial was conducted 250 different surgeries. The data collection instruments included a questionnaire containing Spielberger state-trait inventory (STAI) researcher-made with queries demographic characteristics surgery-related information. Analysis performed...

Objectives: The aim of the current study was to assess prevalence and causes maxillofacial fractures in a five-year period among patients referring Taleghani Hospital, Tehran, Iran. Methods: This retrospective conducted on with from beginning 2013 until end 2017. Demographic factors, fracture site, type, cause fracture, performed treatment were recorded. Results: There 708 fractures; most cases men (85.2%) second third decades life (53.8%). majority mandible incidence rate 64.7%. In...

Zygomatico-coronoid interference is a rare type of mandibular extracapsular ankylosis. There lack information on the treatment these cases in literature. Condylectomy and coronoidectomy are not always best options for limitations movement.A 51-year-old woman presented with mouth-opening limitation due to zygomatic bone displacement coronoid process. The plan was bilateral through an intraoral approach osteotomy right arch extraoral incision. patient able open her mouth approximately 40 mm...

The HeartBert model is introduced with three primary objectives: reducing the need for labeled data, minimizing computational resources, and simultaneously improving performance in machine learning systems that analyze Electrocardiogram (ECG) signals. Inspired by Bidirectional Encoder Representations from Transformers (BERT) natural language processing enhanced a self-supervised approach, model-built on RoBERTa architecture-generates sophisticated embeddings tailored ECG-based projects...

Objectives: Temporomandibular joint (TMJ) involvement in rheumatoid arthritis (RA) patients has been described the literature; however, its incidence varies greatly. In this study, we aimed to determine prevalence and clinical characteristics of TMJ RA patients.Materials Methods: The present study consisted 60 individuals with RA. were assigned two groups, based on involvement: without involvement. We defined findings questionnaires examination by a rheumatologist. symptoms signs recorded...

Objective: Florid cemento-osseous dysplasia (FCOD) is a rare bone lesion that predominantly involves the women’s jaws in middle age. This condition usually asymptomatic and has benign course. Case: paper presents case of FCOD white aged woman, which had affected mandible bilaterally was diagnosed after tooth extraction treated conservatively. We believed contributing factor for outbreak such this susceptible patient. Conclusion: For patients, best management consists regular recall...

The closure of oroantral communications (OACs) is challenging. study aimed to assess the effect titanium meshes in outcome OAC by local flaps. This a prospective randomized, nonblinded clinical trial. Patients with delay and large (≥7 mm 2 ) were studied. randomly divided into groups: group 1, patients underwent through modified Rehrmann buccal advancement flap mesh, 2, flap. primary predictive factor was use mesh. Dehiscence (the breakdown edge flaps without complete reopening defect)...
