Background: Sclerosis of dentinal tubules may be a response to pathological or physiological insult in the crown & root. The mechanism by which apical translucency is produced is still uncertain. The increase in size of the apical zone of sclerotic dentin in human teeth has been used often in forensic science as a method of age estimation. However, only few studies have been done to compare percentage of translucency between vital and non-vital teeth. Conflicting concepts exist regarding the amount of translucent dentin in the vital & non vital teeth and correlation of this variation with age of the subject.
Aims: To investigate the amount and distribution of apical translucent dentin in group-matched vital and non-vital teeth.
Materials And Methods: Study was conducted on 70 extracted teeth, which were subjected for vitality test before extraction, and divided into two groups (vital & non-vital teeth) with a minimum of 35 teeth in each group. Ground sections of 150µ thickness were observed under Stereomicroscope and photographed. The distribution of area and length was measured on the images captured, using PROPLUS IMAGE ANALYSIS SOFTWARE version 4.1.0.0 software.
Results And Conclusions: The present study revealed significant differences (p < 0.05) in apical translucency of dentin, when both vital and non-vital teeth types were compared. There was more apical translucency present in non-vital when compared with vital teeth at any given age. Key words: Apical translucency; vital teeth; non-vital teeth.

This case report details the diagnosis and treatment of dentinogenesis imperfecta in a 6-year-old neutered male Labrador, presenting without concurrent osteogenesis imperfecta. Diagnostic modalities, including radiographs, CT imaging, and histopathological examination, are reviewed in conjunction with the latest literature on canine dentinogenesis imperfecta. This patient presented at a more advanced age than typically reported cases.

Background: Vital pulp therapy (VPT) has recently been reported as an effective approach for preventing and treating carious pulp injury in permanent teeth. Compared with root canal treatment (RCT), which involves complete removal of the pulp tissue, VPT effectively maintains pulp vitality and retains the physiological functions of the pulp. In the research pool, large-scale randomized controlled trials evaluating the treatment outcome of VPT using calcium silicate cements and RCT in cariously exposed permanent teeth are lacking.

Article Synopsis
- * In August 2023, wheat plants in Yunnan showed signs of FHB, with about 10% of the plants affected, making them look bleached and wilted.
- * Scientists collected samples and grew them in the lab to identify the specific types of fungi causing FHB, and they prepared genetic sequences for further research.
Relined fiberglass posts: influence of resin opacity on the bond strength to intraradicular dentin.

This study aimed to evaluate the bond strength between relined fiberglass posts with different composite resin opacities in different thirds of the intraradicular dentin. Thirty single-rooted premolars were endodontically treated and divided into three groups (n=10): fiberglass posts relined with translucent composite resin, fiberglass posts relined with opaque composite resin, and fiberglass posts without relining. After cementation of the posts, the specimens were cut perpendicular to the long axis of the tooth in slices of approximately 1.

Article Synopsis
- The study focused on identifying sexual dimorphism in stillborn hawksbill sea turtles by examining the morphological differences in their gonads using various microscopy techniques.
- Female gonads were characterized by a spindle shape and a grainy texture, while male gonads were ovoid and had a smooth surface, indicating distinct structural differences.
- Microscopic and ultrastructural analyses revealed unique cellular arrangements in females with oocytes and blood vessels, compared to males, which had testicular cords and distinct cell types, confirming these evaluation methods are reliable for sex determination in these turtles.
