Objectives: This study aimed to evaluate the healing rate of non-surgical endodontic treatment between C-shaped and non-C-shaped mandibular second molars.
Materials And Methods: Clinical records and radiological images of patients who had undergone endodontic treatment on mandibular second molars between 2007 and 2014 were screened. The periapical index scoring system was applied to compare healing outcomes. Information about preoperative and postoperative factors as well as the demographic data of the patients was acquired and evaluated using chi-square and multinomial logistic regression tests.
Results: The total healing rate was 68.4%. Healing rates for the mandibular second molar were 70.9% in C-shaped canals ( = 79) and 66.6% in non-C-shaped ones ( = 117). The difference was not statistically significant.
Conclusions: The presence of a C-shaped canal in the mandibular second molar did not have a significantly negative effect on healing after treatment. Instead, proper pulpal diagnosis and final restoration were indicated as having significantly greater influence on the healing outcomes of C-shaped and non-C-shaped canals, respectively.

Investigating the characteristics of the mandibular canal in cone beam CT.

Department of Pediatrics Dentistry and Orthodontics, Faculty of Odonto-Stomatology, Can Tho University of Medicine and Pharmacy, Can Tho City, Vietnam.
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.
Background: Opioids are still being prescribed to manage acute postsurgical pain. Unnecessary opioid prescriptions can lead to addiction and death, as unused tablets are easily diverted.
Methods: To determine whether combination nonopioid analgesics are at least as good as opioid analgesics, a multisite, double-blind, randomized, stratified, noninferiority comparative effectiveness trial was conducted, which examined patient-centered outcomes after impacted mandibular third-molar extraction surgery.

Background: To evaluate the prevalence and characteristics of taurodontism in northern China by using cone-beam computed tomography (CBCT) and assisting the treatment.
Methods: The study involved CBCT scans of 8112 teeth from 507 participants of northern China, comprising 217 males and 290 females aged 18 to 60. Analysis was conducted using Shifman and Chanannel's criteria to assess the prevalence and attributes of taurodontism, examining differences based on tooth position (maxilla and mandible) as well as gender (P < 0.
