Especially in molars that may have sometimes aberrant additional root canals, the complexity of tooth internal morphology in individual cases sometimes does not match to admitted classification rules and underlines the risk of missed anatomy during the endodontic management. To our knowledge, a permanent mandibular second molar with independent five roots, three mesial and two distal, each of them harboring a single canal, was not yet reported. Despite the treatment difficulties this tooth could be successfully approached by using dental operative microscope and cone-beam computed tomography (CBCT) with small field of view. Though CBCT is not a routine imagistic examination, in case of atypical tooth anatomy aiming to establish adequate diagnosis and treatment plan, the successful clinical outcome prevails over the irradiation dose.

Purpose: To examine the impact of placing plain and impregnated retraction cords for two different retraction times on the postoperative gingival margin level and periodontal health.
Materials And Methods: A total of 40 endodontically treated mandibular first molars were selected and randomly allocated into four groups (n = 10/group); A: plain retraction cord for 10 min, B: plain retraction cord, 20 min, C: impregnated (25% aluminum chloride (AlCl) retraction cord, 10 min, D: impregnated retraction cord (25% AlCl), 20 min. Intraoral digital scans were acquired, and periodontal parameters (Plaque index [PI], Bleeding on probing [BOP], and probing depth [PD]) were assessed at baseline, 7 days, and 28 days after retraction.

Teeth, either erupted or impacted, that exceed the normal count are known as supernumerary teeth. They can appear unilaterally or bilaterally, singly or in multiples, and may be located anywhere in both dental arches. Multiple permanent impacted supernumerary teeth are uncommon and are often associated to syndromes but can be idiopathic.

The objective of this cohort study was to examine the relation of tooth wear, adjusted for covariates (age, tooth loss, arch perimeter and intercanine width), on tertiary crowding in Amazon Indigenous populations.
Methods: A sample of 40 Indigenous people in permanent dentition at T0 (baseline) and after 13 years (T1) were evaluated.

BACKGROUND This cone beam computed tomography (CBCT) endodontics study aimed to compare the canal-centering ability and canal transportation of Edgefile X7 and HyFlex EDM files in moderately curved mesiobuccal (MB) root canals of 30 mandibular first permanent molar teeth. MATERIAL AND METHODS Thirty permanent mandibular first molars with 10° and 24° of mesial root curvature were selected and scanned with CBCT. Two experimental groups of 15 each were made: group I: HyFlex EDM, and group II: Edgefile X7.
