The influence of the field of view and voxel size on the contrast-to-noise ratio in cone-beam computed tomography imaging.

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

Materials And Methods: A SedentexCT phantom was scanned using 3D Accuitomo 170 across 3 FOVs (40×40 mm, 60×60 mm, 80×80 mm). Each FOV had 4 settings for kVp and 3 for mA.

Recommendations for Research to Develop a Patient-Centered Clinical Follow-Up Protocol for Oral Epithelial Dysplasia.

Oral epithelial dysplasia (OED) is the primary histological marker for assessing the progression of oral potentially malignant disorders (OPMDs) to cancer. Despite challenges in grading and low inter-pathologist reproducibility, OED severity remains the key predictor of malignant transformation. However, globally accepted guidelines for OED monitoring are lacking, despite calls for individualized management based on host and lesion characteristics.

The effect of calcium hydroxide and double antibiotic paste on radiographic outcomes and periapical MMP-8 levels in regenerative endodontic procedures: a randomized clinical trial.

Objective: 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) of immature permanent mandibular first molars with symptomatic irreversible pulpitis and symptomatic apical periodontitis (SIP/SAP). Additionally, the secondary goal was to evaluate MMP-8 levels during REP using two different intracanal medicaments.

Methodology: The study included 20 patients with immature mandibular first molars exhibiting SIP/SAP.

Is It Time to Consider Implementation of Telemedicine in Current Oral Health Care Services?

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

The contribution of artificial intelligence to reducing the diagnostic delay in oral cancer.

Oral cancer (OC) is the sixth most commonly reported malignant disease globally, with high rates of disease-related morbidity and mortality due to advanced loco-regional stage at diagnosis. Early detection and prompt treatment offer the best outcomes to patients, yet the majority of OC lesions are detected at late stages with 45% survival rate for 2 years. The primary cause of poor OC outcomes is unavailable or ineffective screening and surveillance at the local point-of-care level, leading to delays in specialist referral and subsequent treatment.

Dental radiographic procedures during COVID-19 outbreak and normalization period: recommendations on infection control.

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 to review and revise our current practice of infection control and develop more strict protocols that will prevent nosocomial spread of infection during COVID-19 outbreak and future pandemics. The risk of contamination is high during dental radiography if proper disinfection techniques are not applied.

Potentially premalignant disorder/lesion versus potentially premalignant patient: Relevance in clinical care.

This communication presents a discussion of patient risk factors and outcomes for potentially malignant and malignant lesions in contrast to lesion assessment and lesion management. The shift in consideration may have implications for research and clinical intervention. This compact review discusses several local and systemic components that contribute to the development of malignant changes and discusses whether patients instead of lesions should be defined as having a potentially premalignant condition.

Oral health-related quality of life among institutionalized patients after dental rehabilitation.

Aim: The aim of the present study was to determine the changes in oral health-related quality of life before and 3 months after dental rehabilitation among geriatric patients residing in a state-owned nursing home, using the General Oral Health Assessment Index (GOHAI).

Methods: Data from 40 patients were collected through the administration of a structured questionnaire, as well as from medical records and intraoral examinations. Sociodemographic and behavioral variables, and denture use/length of use were recorded.

Fractal analysis for the assessment of trabecular peri-implant alveolar bone using panoramic radiographs.

Objectives: There is no consensus on the relationship between fractal dimension and trabecular bone complexity. Our aims were to examine the changes in fractal dimension (FD) from peri-implant alveolar bone on digital panoramic radiographs 6 and 12 months after prosthodontic loading and to compare these with baseline values calculated just after loading.

Material And Methods: Three panoramic radiographs taken from 76 implant patients taken (1) after prosthodontic loading (3 months ± 2 weeks after insertion = baseline), (2) 6 months ± 2 weeks after loading, and (3) 12 months ±2 weeks after loading were considered for the study.

Clinical application of a digital method to improve the accuracy of color perception in toluidine blue stained oral mucosal lesions.

Objective: Color perception is an important variable in detecting and assessing oral conditions. The aim was to investigate clinicians' perception of toluidine blue (Tblue) staining compared to digital color analysis, which may impact mucosal lesion detection, affect the decision to biopsy, and biopsy site selection.

Method And Materials: Four oral lesions were stained with Tblue.
