Internal configuration of maxillary molars in a subpopulation of Brazil's Northeast region: A CBCT analysis

Abstract The present study aimed to evaluate the internal configuration of the maxillary molars of a population from the Northeast region of Brazil. Cone-beam computed tomography (CBCT) exams from 512 patients (1501 teeth) were evaluated regarding the anatomical configuration of the root canal system, ac...

Challenges in measuring angles between craniofacial structures

J. appl. oral sci; 27 (), 2019
Abstract Objective: Three-dimensional (3D) angular measurements between craniofacial planes pose challenges to quantify maxillary and mandibular skeletal discrepancies in surgical treatment planning. This study aims to compare the reproducibility and reliability of two modules to measure angles between ...

Age estimation by pulp/tooth area ratio in anterior teeth using cone-beam computed tomography: comparison of four teeth

J. appl. oral sci; 27 (), 2019
Abstract Objectives Age estimation is one of the most important factors in forensic medicine. Measuring secondary dentin deposition using cone-beam computed tomography images is an easy and noninvasive method. The aim of this study was to evaluate cone-beam computed tomography images as a reliable meth...

RFO UPF; 23 (3), 2018
Objetivo: relatar o caso de um paciente idoso portador de defeito ósseo de Stafne. Relato de caso: paciente do sexo masculino, 74 anos de idade, foi atendido na Clínica de Odontologia da União Metropolitana de Educação e Cultura, e, após realização de radiografia panorâmica, foi evidenciada uma ...

Three-dimensional assessment of external apical root resorption after maxillary posterior teeth intrusion with miniscrews in anterior open bite patients

ABSTRACT Objective: The objective of this study was to assess the external apical root resorption (EARR) of the maxillary posterior teeth after intrusion with miniscrews. Methods: Fifteen patients (13 females and 2 males) with age ranging from 14.5 to 22 years (mean 18.1 ±2.03 years) were selected to...

Dentoalveolar evaluation of lower incisors by cbct after treatment with herbst appliance

Braz. dent. j; 29 (6), 2018
Abstract This study aimed to evaluate the effects of the Herbst appliance on the proclination and protrusion of the lower incisors, and to verify if the device causes alveolar bone loss in the anterior region of the mandible. This is a retrospective study. The sample consisted of 35 individuals. The trea...

Validation of cone beam computed tomography as a clinical imaging method for dentin thickness measurement in the danger zone of mandibular molars

RFO UPF; 23 (1), 2018
Objective: to verify the accuracy of cone beam computedtomography (CBCT) for measuring dentin thicknessin the danger zone of mandibular molars in order to validatethis method to be used as a clinical auxiliary. Materialsand method: dentin thickness of the distal wall ofmesial canals was measured at 2 mm ...

Root morphology and number of canals in mandibular central and lateral incisors using cone beam computed tomography

Braz. dent. j; 29 (3), 2018
Abstract Most failures in endodontic treatment of mandibular incisors are due to the presence of a missed canal specifically the lingual. This investigation aimed to examine the root morphology and number of canals in mandibular incisors using cone beam computed tomography (CBCT). Two hundred and seven p...

3-H in 3-D: envisaging beyond the current hype, the hope and hurdles of three-dimensional "virtual planning" in orthognathic surgery

Int. j. morphol; 36 (1), 2018
SUMMARY: Recent technical and technological advancements in orthognathic surgery concepts, intricate in the diagnosis and treatment planning for corrections of dento-facial deformities, have achieved stable oro-dental functional occlusion and facial esthetic harmony. Undeniably, this can be attributed to...

Maxillary sinus floor pneumatization and alveolar ridge resorption after tooth loss: a cross-sectional study

Abstract This is a cross-sectional study that aimed to estimate maxillary sinus floor (MSF) pneumatization in single missing tooth of posterior maxilla, by using cone-beam computed tomography (CBCT). CBCT images were analyzed bilaterally and divided into 2 groups: edentulous site (EdS) - edentulous singl...
