Dentinal translucency and width of cementum: predicting the age over 55 years in South Indian adults using extracted sectioned teeth.

The main intention of this article was to evaluate the reliability of root dentine translucency (RDT) and the width of cementum (CW) in indicating the age over 55 years in forensic and criminal investigations. 600 non-restored, single rooted teeth (300 males and 300 females) which were extracted for periodontal or orthodontic reasons were collected. Each tooth was sectioned longitudinally until the desired thickness (250 µm) was obtained.

Ectopic Eye Tooth Management: Photobiomodulation/Low-Level Laser Emission Role in Root Resorption after Fixed Orthodontic Treatment.

Aim: This study evaluates the role of low-level laser emission/photobiomodulation (LE/P) in quantitative measurements of root resorption (QRR). The application of LE/P performed after each orthodontic activation with four types of treatment intervention (TI) on the root resorption (RR) after fixed orthodontic treatment (FOT) of the upper arch with ectopic eye tooth/teeth [EET] was investigated. Materials and Methods: Thirty-two orthodontic patients scheduled for FOT were selected and assigned to the four groups.

Craniofacial morphology in Apert syndrome: a systematic review and meta-analysis.

This meta-analysis aims to compare Apert syndrome (AS) patients with non-AS populations (not clinically or genetically diagnosed) on craniofacial cephalometric characteristics (CCC) to combine publicly available scientific information while also improving the validity of primary study findings. A comprehensive search was performed in the following databases: PubMed, Google Scholar, Scopus, Medline, and Web of Science, an article published between 1st January 2000 to October 17th, 2021. PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed to carry out this systematic review.

Reliability of dentin translucency and incremental cemental lines in age estimation using light and stereomicroscopes: A comparative study.

Age estimation of the dead and human remains has been challenging in forensic medicine, both in mass disasters and criminal investigations. There are several approaches to accurately evaluate age, each with its own benefits and drawbacks. Dentine translucency (DT) and incremental cemental lines (ICL) have often been used for age estimation in living adults and unknown skeletal remains.

Periodontal Clinical Parameters as a Predictor of Bite Force: A Cross-Sectional Study.

Objective: To investigate the correlation of periodontal parameters and bite force in different stages of periodontitis after phase I periodontal therapy.

Methods: Periodontal clinical parameters such as mobility, attachment loss, gingival recession, and percentage of bone remaining were recorded at the mandibular first molar region after phase I therapy in subjects categorized according to the stage of periodontitis. Corresponding bite force was recorded at the first mandibular molar region using a bite force device after phase I therapy.

Anti-geometric diffusion for adaptive thresholding and fast segmentation.

We utilize an anisotropic diffusion model, which we call the anti-geometric heat flow, for adaptive thresholding of bimodal images and for segmentation of more general greyscale images. In a departure from most anisotropic diffusion techniques, we select the local diffusion direction that smears edges in the image rather than seeking to preserve them. In this manner, we are able rapidly to detect and discriminate between entire image regions that lie near, but on opposite sides of, a prominent edge.

Integral invariants for shape matching.

For shapes represented as closed planar contours, we introduce a class of functionals which are invariant with respect to the Euclidean group and which are obtained by performing integral operations. While such integral invariants enjoy some of the desirable properties of their differential counterparts, such as locality of computation (which allows matching under occlusions) and uniqueness of representation (asymptotically), they do not exhibit the noise sensitivity associated with differential quantities and, therefore, do not require presmoothing of the input shape. Our formulation allows the analysis of shapes at multiple scales.
