AI Article Synopsis

  • The mandibular canal (MC) is a crucial anatomical structure that needs careful assessment using cone beam computed tomography (CBCT) before surgical procedures.
  • A study analyzed 112 CBCT images of Vietnamese patients to determine the MC's dimensions and its relationship with nearby anatomical features.
  • Results showed that the average diameter of the MC was similar regardless of missing teeth, highlighting the importance of CBCT in treatment planning to prevent nerve damage during dental surgeries.

Article Abstract

Context: The mandibular canal (MC) is an essential landmark that should be considered before any surgeries. Therefore, accurately assessing the location and characteristics of the MC in cone beam computed tomography (CBCT) imaging is very important.

Aims: To determine the characteristics of the MC in relation to adjacent anatomical structures in CBCT projections.

Settings And Design: The convenience sampling method.

Methods And Material: This was a retrospective study of 112 CBCT images of Vietnamese patients aged 18 to 69 years, taken for clinical indications between 2018 and 2023. The evaluation was carried out by comparing and arranging the anatomical structures of different planes in three-dimensional space to assess and measure relevant dimensions.

Statistical Analysis Used: Independent samples T-test.

Results: The average diameter of the MC from the apex of the second premolar to the distal apex of the second molar, if there were no missing teeth in this segment, was 2.58 ± 0.52 mm (right) and 2.55 ± 0.54 mm (left). If there were a missing tooth in this segment, the measurements were 2.51 ± 0.79 mm (right) and 2.47 ± 0.45 mm (left). The difference between the two sides regarding the presence or absence of a missing tooth was not statistically significant.

Conclusions: The precise localization of the MC related to the tooth apex and the diameter of the MC can vary in each person. CBCT indications should be considered when establishing treatment planning to avoid damaging the inferior alveolar nerve in the MC.

Pulp chamber and root canal obliteration (PCO/RCO) presents a challenge for clinicians when nonsurgical endodontic treatment is indicated. Guided endodontics (GE) aims to precisely locate the root canal (RC) system while preserving as much pericervical dentin as possible. GE involves integrating cone-beam computed tomography (CBCT) of the affected tooth with a digital impression of the maxillary/mandibular arch, allowing for careful planning of the drilling path to the RC system through a three-dimensional (3D) static guide.

Aim: This study aims to analyze the root canal configuration system of mandibular first premolars in the Bengali subpopulation using cone-beam computed tomography (CBCT).

Materials And Methods: Based on Vertucci's classification, the root canal morphology of 100 randomly selected mandibular first premolars in 56 males and 44 females from the Bengali subpopulation of West Bengal was assessed in vitro. The location of the apical foramen, lateral canal, C-shaped canal, types of canal orifice cross-sections, minor constriction diameter, tooth length, and root length were noted.

The preservation of the original configurations of root canals during endodontic preparation is crucial for treatment success. Nickel-titanium (NiTi) rotary systems have been refined to optimize canal shaping while minimizing iatrogenic errors. This study aimed to evaluate and compare the shaping efficacy of the novel R-Motion (RM) and the established WaveOne Gold (WG) systems using micro-computed tomography (micro-CT).

Objective: This study compared the fracture load, stress distribution, and survival probability under cyclic loading of extensively restored teeth treated with multisonic irrigation with those treated with conventional instrumentation, with or without a post.

Methods: Mesial-occlusal-distal cavities were prepared in 30 human mandibular premolars. The teeth were randomly divided into 3 groups of 10 based on the endodontic and restorative procedures: (1) Root canal treatment (RCT) followed by resin composite restoration (control group), (2) RCT followed by a glass fiber post restoration (conventional group), and (3) minimal instrumentation plus multisonic irrigation followed by resin composite restoration (GW group).
