Publication: Comparative accuracy of the Clearing Technique, CBCT and Micro-CT

Despite the considerable number of studies published on the internal anatomy of posterior teeth, very little information exists regarding the accuracy of clearing, CBCT, and micro-CT methods to diagnose the morphology of the root canal anatomy. Therefore, the aim of this study was to compare the accuracy of the clearing technique and CBCT scanning in the assessment of the mesial root canal configuration of mandibular first molars, using micro-CT imaging system as a reference standard.

Peg-Shaped Lateral Incisors (Conoid)

Peg-Shaped Lateral Incisors

The most common anomaly in tooth shape in the anterior of the secondary dentition is the peg-shaped (or cone-shaped) lateral incisor, occurring in 1-2% of the population. The tooth is generally conical in shape, broadest cervically, and tapers toward the incisal to a blunt point. Several studies of the identical twins seem to indicate that missing and peg-shaped lateral incisor teeth may be varied expressions of the same generic trait. A most unusual occurrence is that of peg-shaped maxillary central incisor. Peg-shaped teeth develop from one facial lobe (instead of the three facial lobes normally present on anterior teeth).

Publication: Review on Dentinal Microcracks - ETopics


The dentinal radicular microcrack is a difficult clinical problem to diagnose and treat, and it is one of the most common reasons for tooth extraction. These microcracks start in the radicular dentin, and laboratory studies have linked crack formation to some routine endodontic procedures, namely root canal preparation, obturation, and retreatment. Most of these studies were performed using destructive methods, such as the sectioning technique, previously developed for the study of the internal anatomy of teeth. Nowadays, technological advances in the field of imaging may lead to a more thorough understanding of dentinal microcracks. This article seeks to critically appraise the methodological aspects involved in the study of dentinal radicular microcrack formation after root canal preparation, obturation, and retreatment.
