Nicodemo's method on dental development: a cross-sectional study with 3,271 children and adolescents.

Civil and criminal forensics utilize dental development to estimate age. The method of Nicodemo, Moraes, and Médici Filho (NMM) is a popular dental age estimation tool in South America; however, it lacks a scientific basis for applications in contemporary forensic practice. This research included the largest sample ever collected in Brazil for a similar purpose.

Prevalence and Characterization of External Cervical Resorption Using Cone Beam Computed Tomography.

Introduction: The aim of this study was to assess the prevalence of external cervical resorption (ECR) and characterize the cases of ECR using cone beam computed tomography (CBCT).

Methods: High-resolution CBCT scans of 6216 patients (2280 males and 3936 females), consecutively acquired during the period July 2021 to March 2022, were analyzed. Identified cases of ECR were characterized by 3 evaluators regarding lesion height, circumferential spread, portal of entry proximity to root canal, stage, location, and width.

Radiographic dental age estimation applying and comparing Demirjian's seven (1973) and four (1976) teeth methods.

To apply Demirjian's seven (1973, D) and four (1976, D) teeth methods in a sample of Brazilian children and compare their performances for age estimation. Panoramic radiographs of 1200 children (600 females and 600 males) were collected from Southeast Brazil. The children were equally distributed (n = 60 females and 60 males) between age intervals of 1 year between 6 and 15.

Effect of decompression and online transmission on the dimensional changes of .stl files generated by intra-oral scanning.

Intraoral scans became part of the virtual planning in Dentistry. In the new scenario of digital workflows, dental clinics and laboratories had to establish an online communication that requires the compression, decompression, and transmission of 3D files. Knowledge about the effects of these procedures on the dimensional properties of the files is fundamental to ensure a more realistic virtual planning.
