Variations in the root canal anatomy of multirooted teeth represent a continuous challenge to the practitioners. Knowledge of the internal canal anatomy is the key to the success of endodontic treatment. Commonly, in the literature, there are two fused roots with three canals in mandibular second molar teeth, which can be diagnosed as a C-shaped ca...
Background: The internal anatomy is a complex system and root canal morphology varies between teeth, especially in maxillary second premolars. Objective: The purpose of this present study is to identify the variations in root and root canal morphology of the upper second premolar. Methods: A retrospective study on 197 maxillary second premolars, wh...
The present study aimed to evaluate the internal configuration of the maxillary molars of a population from the Northeast region of Brazil. Cone-beam computed tomography (CBCT) exams from 512 patients (1501 teeth) were evaluated regarding the anatomical configuration of the root canal system, according to Vertucci's classification. The images were...

Objective
To compare second molar angulation to the occlusal plane with cephalometric measurements corresponding to AP skeletal discrepancy.
Materials and Methods
72 patients' pre-orthodontic records were analyzed. A plane was constructed along the cusps of the upper second molar and measured to a proxy for the occlusal plane. The angle between the planes was measured. ANB, Wits appraisal, U1-SN, IMPA, A-B perpendicular to Frankfort, and overjet were measured on the patients' cephalograms. Generalized additive mixed model analysis was performed to analyze the relationship between the second molar angulation and the cephalometric measurements.
Results
All six cephalometric measurements showed a significant relationship with the second molar angulation, with Class III patients having a larger angle than Class II and I patients.
Conclusions
Class III patients have upper second molars that are significantly tipped from the occlusal plane. The second molars require special attention for correction prior to orthognathic surgery for Class III patients in order to avoid deleterious effects from the malpositioned teeth.
