This study uses machine learning (ML) to elucidate the contact relationship between mandibular third molar (M3M) and inferior alveolar canal (IAC), leading three major contributions; (1) The first publicly accessible PR image dataset with semantic annotations for 1,478 IACs M3Ms from 1,010 patients is introduced, which includes challenging cases, such as false positive contacts, CBCT images gold standard, (2) Established radiological indicators M3M-IAC were extracted features using digital...

Akcay I, Ilhan B, Dundar N. Comparison of conventional and digital radiography systems with regard to radiopacity root canal filling materials. International Endodontic Journal , 45 730–736, 2012. Abstract Aim To compare the five materials as measured on digitized E‐speed films, storage phosphor plate CCD sensor images. Methodology Radiopacity Resilon cones Epiphany, MM‐Seal, EndoREZ AH Plus sealers were investigated. Ten acrylic plates prepared filled Samples radiographed together samples...

Dental professionals have always been meticulous about infection control due to high risk of cross-contamination during dental procedures. Nevertheless, there is an urgent need review and revise our current practice develop more strict protocols that will prevent nosocomial spread COVID-19 outbreak future pandemics. The contamination radiography if proper disinfection techniques are not applied. This document provides advice guidance for when practicing pandemic.

The impact of Candida sp. in the development oral cancer remains uncertain and requires sensitive analytical approaches for clarification. Given invasive capabilities these microorganisms penetrating invading host tissues through hyphal invasion, this study sought to detect presence five biopsy tissue samples from non-smoker patients. Samples were obtained patients at varying stages carcinogenesis, including dysplasia, carcinoma situ, OSCC, histologically benign lesions, analyzed using...

The aim of the present study was to determine changes in oral health-related quality life before and 3 months after dental rehabilitation among geriatric patients residing a state-owned nursing home, using General Oral Health Assessment Index (GOHAI).Data from 40 were collected through administration structured questionnaire, as well medical records intraoral examinations. Sociodemographic behavioral variables, denture use/length use recorded. GOHAI questionnaire completed by same examiner....

The primary goal is to evaluate the effects of two different intracanal medicaments, calcium hydroxide [Ca(OH)2] and double antibiotic paste (DAP), on radiographic outcomes during regenerative endodontic procedures (REP) immature permanent mandibular first molars with symptomatic irreversible pulpitis apical periodontitis (SIP/SAP). Additionally, secondary was MMP-8 levels REP using medicaments.

Context: Trabecular bone around dental implants has been rarely evaluated by means of fractal analysis. Aims: The aim was to assess dimension (FD) values peri-implant 12 months after implant installation and compare these FD with those healthy control sites on the contralateral side area. Materials Methods: Panoramic radiographs from 29 patients mandibular functioning for were analyzed. Radiographs digitized at 300 dpi 256 grey levels. Healthy trabecular corresponding implant-free area...

Objective: Color perception is an important variable in detecting and assessing oral conditions. The aim was to investigate clinicians' of toluidine blue (Tblue) staining compared digital color analysis, which may impact mucosal lesion detection, affect the decision biopsy, biopsy site selection. Method Materials: Four lesions were stained with Tblue. Digital analyses eight areas on each image completed considered as gold standard (GS). Twenty specialists ranked these according their...

This study investigated the impact of field view (FOV), voxel size, and exposure parameters on contrast-to-noise ratio (CNR) in cone-beam computed tomography (CBCT).

<title>Abstract</title> Background To assess the knowledge levels of postgraduate students in departments oral and maxillofacial radiology (OMFR) surgery (OS) regarding diagnostic adjuncts for mucosal lesions. Methods Postgraduate enrolled OMFR OS programs across dental faculties nationwide between 2019 2021 were included. A total 434 participants selected based on specific criteria. 40-question questionnaire with items formulated by specialists at least 15 years experience covered basic...

Telemedicine offers an excellent opportunity to provide continuing health care for those in need during local/global pandemics and disasters. It provides a safe effective communication tool between professionals can be used as "forward triage" manage medical/dental emergencies minimize the contact patients clinicians coronavirus disease (COVID-19) pandemic. Patients with noncommunicable diseases, like cancer, diabetes, cardiovascular, or chronic respiratory may present critical problems due...

A few cases of pneumonia were reported by Wuhan Municipal Health Commission in Wuhan, Hubei Province, Republic China and this mysterious was recognized as novel coronavirus disease (COVID-19) the course time on 31 December 2019. Based literature knowledge, COVID-19 outbreak came into existence through an animal-to-human transmission, then continued human-to-human diffusion. Especially dentists among medical professionals are at high-risk group SARS-CoV-2 virus contamination because several...

Abstract BACKGROUND: It is still controversial whether axillary lymph node dissection can be omitted after negative sentinel biopsy in breast cancer patients with clinically positive axilla at presentation treated neoadjuvant chemotherapy (NAC). The aim of this study was to analyze SLN could useful these patients. METHODS: After NAC 112 cytology-proven metastasis the time diagnosis, SLNB using radioisotope and blue dye performed including completion between 2008 2012. results...

The aim of this study was to evaluate the accuracy endodontic file length measurements E-speed radiographs, Digora storage phosphor plates, and Schick charge-coupled device sensors, with a secondary assessing influence image enhancement on measurement accuracy. Forty-seven extracted mandibular first premolar teeth were selected. ISO size 8, 10, 15 files inserted into each canal, fixed when tip seen at apical foramen. mounted in acrylic blocks exposed using films, sensors. Two radiologists...
