Abstract

Purpose: This study evaluated the apical root canal system of maxillary second molars, in which conventional endodontic treatment had failed. Materials and Methods: One hundred eighteen extracted endodontically failed maxillary second molars were examined to investigate the root canal morphology using clinical photographs. High-resolution cross-sectional images at the 3mm level from the root apices were taken to evaluate the anatomic variations and canal cleanliness. The incidence of anatomic variations and canals containing debris were evaluated statistically. Results: One (0.85%) maxillary second molar had four separate roots, while 52 (44.07%) had three separate roots. The remaining 65 (55.08%) showed 6 different types of fusion in their roots. As the number of fused roots increased from none to three, the incidence of isthmuses in the cross-sectional images increased significantly from 43.40% to 76.92% in 2-root fusion and 88.46% in 3-root fusion. In addition, the occurrence of less-cleansed canals increased from 22.64% to 38.46% and 53.85%, respectively (p<0.05). Sixty four teeth (54.24%) had 3 canals while 38(32.2%) had additional canals; most of them were located in the MB roots (81.58%). Seventy six (64.41%) had isthmuses in the apical region and 58 out of 76 were located in MB roots. Condlusions: Logistic analysis indicated that the less division of roots was associated significantly with the occurrence of insufficient cleaning during endodontic treatment (OR=1.765, p<0.05), while the presence of an additional canal showed no association.

Abstract

The present study was conducted to assess the growth changes of human chin in childhood and adolescence at various stages of skeletal maturation using metallic implant installed in mandibular body. Lateral cephalographs including 23 subjects (9 males and 14 females) between 7-18 years old were used, which had been taken at University of California in San Francisco and kept at University of the Pacific. Three lateral cephalographs were chosen for each subject according to CVM (Cervical Vertebral Maturation) method (CVM stage 1 to 2, CVM stage 3 to 4, and CVM stage 5 to 6) which assess the extent of the skeletal maturation using the second, third, and fourth cervical vertebrae. V-ceph was used in order to mark the 8 landmarks (S, N, A, B, Pog, Me, Go, Imp) on lateral cephalographs and obtain 8 angular and linear measurements(ANB, SNPog, SN-GoMe, Imp-B, Imp-Pog, B-Pog//GoMe, GoMe B, GoMe Pog). Among 8 measurements, ANB, SNPog, SN-GoMe, B-Pog//GoMe, GoMe B showed statistically significant growth changes at various stages of skeletal maturation according to CVM method, while there were no significant differences on Imp-B, Imp-Pog, GoMe Pog. The results suggest that the increasing prominence of human chin is greatly influenced by the vertical growth of B point area, in addition to the change and growth in chin and mandible proper.

Abstract

The treatment of skeletal Class II growing patient is to move the mandible into the Class I molar positon via facilitating mandibular growth. The functional appliances are to be designed to exert three major functions such as palatal expansion, forward growth of mandible and increase of the posterior vertical dimension. One of the devices that can achieve both the palatal expansion and the eruption of the mandibular molar is the Twin-Block introduced by Clark in 1982. In this part, we present the treatment method with Twin-Block functional appliance for the correction of skeletal Class II growing patient.

Abstract

Trifid mandibular canal (TMC) is one of the anatomical variation of mandibular canal with clinical importance. An extra mandibular canal may explain inadequate anesthesis and be damaged causing paresthesia or bleeding during mandibular surgery. CBCT with high-level spatial resolution is an useful tool for the detection of mandibular canal and its variation. The aim of this report is to present a case of trifid mandibular canal with CBCT images and to give information on this anatomical variation of mandibular canal.
