o bjectives: the aim of this study was to determine the cementum thickness in the first molars of patients with localized aggressive periodontitis (lap) compared to healthy individuals. materials and methods: this case-control study compared eight first molar teeth af-fected by lap with eight third molar teeth of healthy individuals. the teeth were dis- infected by immersion in 10% buffered for...

ABSTRACT Root resorption is characterized by the loss of cementum and / or dentin from tooth root as a result internal external odontoclastic action. This case reports premature cervical deciduous teeth in an 8-year-old boy. Large on mesial faces maxillary mandibular right left canines (teeth #53, #63, #73 #83), with asymptomatic pulp involvement, was detected during routine radiographic examin...

This report describes the non-surgical treatment of an invaginated maxillary lateral incisor with two fused roots. The mesial root had a C-shaped canal, while the distal one had a type III dens invagination. Cone-beam computed tomography (CBCT) was used to help with the diagnosis and treatment decision making. Clinical and radiographic follow-up revealed satisfactory periapical repair and absen...

A mandibular first molar requiring root canal therapy was found with five canals, three mesial canals, and two distal canals. Initially, four canals (mesiobuccal, mesiolingual, distobuccal, and distolingual) were identified. The mesiobuccal and mesiolingual canals were found in their normal locations, and a fifth canal was noted between these two. This case demonstrates a rare anatomical config...

The present study used ultra-high-resolution micro-computed tomography (CT) to clarify the classification of root canal morphologies and incidence accessory canals in maxillary first molar mesiobuccal (MB) root. Aspects relationship with reinfection during or after endodontic treatment were also investigated. Molar three-dimensional structure, pulp cavity, examined on micro-CT images 100 Japane...

canals prepared with different enlargements using single-file reciprocating systems (Reciproc and WaveOne) and a conventional multi-file rotary (BioRaCe) system by microcomputed tomographic analysis. Thirty mesial roots of mandibular molars with moderate curvature (10° to 20°) presenting a type II Vertucci canal configuration and similar internal volume were chosen and scanned at an isotropic r...

This study aimed to evaluate the cause-effect relationship between canal preparation with ProTaper Universal (PTU) system and dentinal defects formation using micro-computed tomography (micro-CT) analysis. Forty mesial canals of mandibular molars with a type II Vertucci's canal configuration were scanned at an isotropic resolution of 14.16 µm. The sample was assigned to an experimental (n = 30)...

The aim of this investigation was to compare root resorption in the same individual after application of continuous intrusive and extrusive forces. In nine patients (mean age 15.3 years), the maxillary first premolars were randomly intruded or extruded with a continuous force of 100 cN for eight weeks. Eleven maxillary first premolars from six randomly selected orthodontic patients served as co...

BACKGROUND Recent studies reported on the very complex morphology of the pulp system in equine cheek teeth. The continuous production of secondary dentine leads to distinct age-related changes of the endodontic cavity. Detailed anatomical knowledge of the dental cavities in all ages is required to explain the aetiopathology of typical equine endodontic diseases. Furthermore, data on mandibular ...
