How protocol, posts, and experience affect fracture detection in multi-rooted teeth using cone-beam computed tomography: an ex vivo experimental study.

Objectives: This study aimed to evaluate the influence of cone-beam computed tomography (CBCT) acquisition protocol, the presence of intraradicular metal post, and examiner experience on the detection of complete root fractures in multi-rooted teeth.

Methods: Twenty human molar teeth filled with gutta-percha were placed into artificial alveoli created in bovine ribs. The sample was divided into two groups based on the presence or absence of intraradicular posts in the distal roots.

Cone Beam Computed Tomography Impact on Diagnosis, Treatment Planning and Confidence in Endodontic Decision-Making: A Systematic Review.

This systematic review evaluated how CBCT impacts diagnosis, treatment planning (TP) and confidence in endodontic cases compared to intraoral radiography (IR). PubMed/MEDLINE, Cochrane-CENTRAL, Embase, Scopus, LILACS, Web of Science and Google Scholar databases were searched. Information regarding changes in the diagnosis, TP and confidence after CBCT was evaluated.

3D-printed Model for Preclinical Training in Oral Radiology: Anatomic and Pathological Conditions.

Objective: The aim of this study was to evaluate the impact of a 3D-printed model with simulated oral changes on the teaching of radiographic evaluation.

Methodology: A model of an adult patient with several simulated alterations was designed, including impacted teeth, dentigerous cyst, mesiodens, coronal fractures, periodontal resorptions, periapical lesions, and exostoses. The radiographic images obtained were evaluated by postgraduate students using a questionnaire.

Patient knowledge and misconceptions about imaging exams and X-rays: the need for clearer guidance in dental care.

Objective: To assess patients' knowledge and possible misconceptions regarding imaging exams and their association to ionizing radiation.

Methods: Patients who sought dental care at the Federal University of Santa Maria Dental School (Brazil) were invited to enroll in the study. Patients filled out a questionnaire that covered demographic information, knowledge regarding imaging exams, X-rays, dental radiographs, and information sources (internet or dentist/physician).

New scenarios for training in oral radiology: clinical performance and predoctoral students' perception of 3D-printed mannequins.

Objectives: This study aimed to evaluate the impact of 3D-printed mannequins on the training of predoctoral students.

Methods: Two 3D-printed training models were developed: a traditional model that simulates a sound adult patient and a customized model with pathological and physiological changes (impacted third molar and edentulous region). Students accomplished their pre-clinical training divided into a control group (CG, n = 23), which had access to the traditional model, and a test group (TG, n = 20), which had access to both models.

Influence of examiner calibration on clinical and MRI diagnosis of temporomandibular joint disc displacement: a systematic review and meta-analysis.

Objectives: This study aimed to verify the accuracy of clinical protocols for the diagnosis of disc displacement (DD) compared with MRI, considering examiners' calibration.

Methods: PubMed, Cochrane (Central), Scopus, Web of Science, LILACS, Embase, Science Direct, Google Scholar, and DANS EASY Archive databases were searched. Two reviewers independently screened and selected the studies.

Tomographic Planning of Dental Implants Using a Smartphone: Linear Measurements and Implant Selection- A Cross-Sectional Study.

Purpose: This study assessed the accuracy of linear measurements and dental implant selection performed in a smartphone application compared to a computer software.

Materials And Methods: Forty-four DICOM files from the posterior mandible in partially edentulous patients were evaluated by three trained and calibrated examiners. Images were analyzed using three visualization methods: cross-sectional view (CScr) and coronal (CSco) plane using the CS 3D Imaging software, and coronal (DRco) plane using the DroidRender smartphone application.

Smartphone Use for Tomographic Evaluation: Application in Endodontic Diagnosis.

Introduction: Portable equipment that allows quick exchanges of information, such as smartphones, is increasingly important in dentistry. Thus, they have become frequently used, with the potential to contribute to the tomographic evaluation. This study aimed to evaluate the accuracy of smartphone applications for diagnosing the root canal system (RCS) and measuring the root canal length.

TMD diagnosis: Sensitivity and specificity of the Fonseca Anamnestic Index.

Objective: To verify whether the Fonseca Anamnestic Index (FAI) has adequate sensitivity and specificity to be used in the diagnosis of temporomandibular disorder (TMD).

Methods: Two hundred-sixty-five participants with symptoms of TMDs were assessed through the FAI and through the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD) and then classified as sick or non-sick. The sensitivity, specificity, and predictive values of the FAI in relation to the RDC/TMD were calculated using the STATA 14.

Treatment of myofascial pain with a rapid laser therapy protocol compared to occlusal splint: A double-blind, randomized clinical trial.

Objective: To compare the effect of a rapid low-level laser therapy (LLLT) protocol to Michigan occlusal splint in the treatment of myofascial pain, as well as to evaluate their impact on Oral Health-Related Quality of Life (OHRQoL).

Methods: Thirty participants were randomly allocated into three groups: G1: occlusal splint (n = 11), G2: LLLT (n = 10), and G3: LLLT placebo (n = 9). LLLT and placebo were applied in the points of pain upon palpation.

Rapid LLLT protocol for myofascial pain and mouth opening limitation treatment in the clinical practice: An RCT.

Objective: To evaluate the effect of a rapid treatment protocol of low-level laser therapy (LLLT) in patients with myofascial pain and mouth opening limitation.

Methods: Twenty patients were randomly allocated into the laser group (LG) (n = 10) and the placebo group (PG) (n = 10). Two LLLT sessions or placebo were performed.
