Root canal conicity determination of primary second molars using nanotomography: An in vitro study.

Background: The conicity of the root canals of primary teeth is an important measure for endodontic therapies. However, determining this conicity depends on the methods employed, which requires further investigation.

Aim: The aim of this study was to determine the conicity of the root canals of the upper and lower primary second molars using nanotomography (nCT).

Association between developmental defects of enamel and early childhood caries in children under 6 years old: A systematic review and meta-analysis.

Early childhood caries (ECC) are an oral health problem worldwide in children under 6 years of age. This disease of rapid development has a multifactorial etiology, and one of the possible risk factors is developmental defects of enamel (DDE), such as hypoplasia and opacities. The aim of this systematic review was to evaluate the association between DDE and ECC in children under 6 years of age.

Quality assessment of clinical practice guidelines for the management of paediatric dental emergencies applicable to the COVID-19 pandemic, using the AGREE II instrument. A systematic review.

Objective: To assess the quality of Clinical Practice Guidelines (CPG) related to the management of paediatric dental emergencies applicable to the COVID-19 pandemic, through the use of the measuring instrument AGREE II (Appraisal of Guidelines for Research and Evaluation in Europe).

Sources And Data Collection: A rigurous online search of CPG was accomplished among the main CPG compilers: National Institute for Health and Care Excellence (NICE), National Guideline Clearinghouse, Agency for Healthcare, Research and Quality (AHRQ), Andalusian Health Technology Assessment Department (AETSA), American Academy of Family Physicians, Tripdatabase. Furthermore, because of the need to identify CPG that meet the inclusion criteria, a manual search, among the main national and international dental organizations as well as recognized web sites, was also accomplished.

Spatial analysis of condyle position according to sagittal skeletal relationship, assessed by cone beam computed tomography.

Background: The study aims to compare the condylar position in patients with different anteroposterior sagittal skeletal relationships through a cone beam computed generated tomography (CBCT) imaging generated space analysis.

Methods: This was a retrospective study of clinically justified, previously taken CBCT images of 45 subjects. Based on a proper sample calculation, three groups of 15 CBCT images each were made according to their ANB angle and facial pattern: class I (normo facial pattern) and class II and III (long facial pattern).
