Objectives: Cone beam computed tomography (CBCT) is an innovative dental of imaging system characterized by rapid volumetric imaging with patient exposure to a single dose of radiation. The present study was carried out to compare the linear measurements obtained with CBCT and digital caliper in 20 mandibles from human cadavers.
Study Design: A total of 4800 linear measurements were measured between different mandibular anatomical points with CBCT and digital caliper. The real measurements were defined as those obtained with the digital caliper. Posteriorly, the mandibles were scanned to obtain the CBCT images, with software-based measurements of the distances.
Results: The measurements obtained with the digital caliper were greater. The CBCT technique underestimated distances greater than 100 mm.
Conclusions: CBCT allows to obtain linear mandibular anatomical measurements equivalent to those obtained with digital caliper. The differences existing between both methods were clinically acceptable. Key words:Computed tomography, cone beam CT, accuracy, reliability, digital caliper.

Objectives: This study compared the clinical accuracy of two different stationary face scanners, employing progressive capture and multi-view simultaneous capture scanning technologies.
Methods: Forty dentate volunteers participated in the study. Soft tissue landmarks were marked with a pen on the participants' faces to measure the distances between them.

Objective: To evaluate volumetric changes over time in teeth treated with the Hall Technique (HT) and their opposing teeth. Secondary aims included assessing occluso-vertical dimension (OVD), temporomandibular joint (TMJ) function, and children's treatment perceptions.
Methods: Twenty-eight children (5-9 years-old) requiring HT treatment for one first primary molar were recruited.

The regional variation of the femur bone is influenced by sex, stature geographical area and heredity, as the environment plays an important role in the developmental process. This cross-sectional descriptive purposive study was done on 150 (64 right and 86 left) fully ossified dry human femur of Bangladeshi people to find out the variation of neck length on anterior and posterior aspect. Sample was collected in the Department of Anatomy, Mymensingh Medical College, Bangladesh from January 2019 to December 2019.

Background: Knowing the available dental space in a patient is crucial for orthodontists to develop a good treatment plan.
Objectives: To compare and evaluate the reliability, reproducibility, and accuracy of three measurement methods on models: conventional, mobile app, and digital software.
Materials And Methods: Maxillary and mandibular dental plaster models of 20 subjects with permanent dentition were analyzed.

Background: The composite physiologic index (CPI) was developed to estimate the extent of interstitial lung disease (ILD) in idiopathic pulmonary fibrosis (IPF) patients based on pulmonary function tests (PFTs). The CALIPER-revised version of the CPI (CALIPER-CPI) was also developed to estimate the volume fraction of ILD measured by CALIPER, an automated quantitative CT postprocessing software. Recently, artificial intelligence-based quantitative CT image analysis software (AIQCT), which can be used to quantify the bronchial volume separately from the ILD volume, was developed and validated in IPF.
