Background: Modern management of carious lesions has been targeted upon using remineralizing agents. This study investigated the remineralization potential of apacider gel (AG) and casein phosphopeptide-amorphous calcium fluoride phosphate (CA) on enamel and cementum around the cavosurface area of the ceramic margin.
Material And Methods: Seventy-five extracted human mandibular molars were sectioned at 0.8 mm above and below the cemento-enamel junction (CEJ) to remove the CEJ portions and replaced them with glass ceramic disks by bonding them to the crown and root portions with resin cement. The enamel and cementum area of 4x4 mm2 surrounding ceramic was demineralized with Carbopol-907. The demineralized surfaces were treated with either AG or CA, while one group was left with no treatment (NT) and served as control. Vickers microhardness was determined before-, after demineralization, and after remineralization. The percentage of hardness recovery (%HR), and remineralization potential (%RP) were analyzed with ANOVA and Bonferroni's test (α=0.05). Polarized light microscopy (PLM) was assessed for lesion depth. Scanning electron microscopy (SEM) was investigated for surface alterations.
Results: Significant differences in remineralization were found upon various remineralizing agents compared to NT for both enamel and cementum (<0.05). No significant difference in %HR and %RP was observed between AG and CA (>0.05). However, AG signified greater decrease in lesion depth and better improvement in surface characteristics for both enamel and cementum than CA.
Conclusions: AG possesses comparable remineralization ability to CA. However, decreasing in carious lesion depth was evinced with using AG more than CA. AG was recommended as a potential remineralization material for handling initial caries for both enamel and cementum. Apacider, artificial carious lesion, CCP-ACFP, remineralizationCare Team.

Although the modulus of elasticity of the human periodontal ligament (E) values used in dentistry widely ranged from 0.01 to 175 MPa, the exact E value has not been determined. This study aimed to verify whether and how E values affect the stress distribution over the tooth and periodontium structures, and to determine the appropriate E range.

Introduction: In the forensic field, having accurate understanding of the macroscopic and microscopic alterations that occur in teeth when exposed to temperatures has remarkable significance. The preservation of delicate incinerated teeth is crucial in fire investigations that pertain to the temperature exposed, as well as the identification of victims. This preservation is necessary in order to conduct macroscopic and microscopic ultra-structural examinations, which provide valuable insights into the structural alterations that dental tissues undergo when exposed to low to high temperatures.

Article Synopsis
- The study aimed to analyze craniofacial tissue aging in a genetically diverse HET3 mouse model and determine if the hormone 17-alpha estradiol (17αE2) could enhance tissue health alongside increased longevity in male mice.
- Male HET3 mice were categorized into age groups and treated with a diet supplemented with 17αE2 to observe changes in craniofacial tissue volume and density.
- Results showed that while some aspects of tissue structure changed with age, treatment with 17αE2 positively affected cementum and dentin, suggesting it may help improve the health of aging dental tissues in male mice.

Article Synopsis
- Limited research exists on coronal cementum formation, particularly in impacted wisdom teeth.
- A histological and analytical examination of an impacted wisdom tooth from a 46-year-old female revealed widespread coronal cementum on the enamel with connections between them.
- Findings suggest that the presence of reduced enamel epithelium may be linked to coronal cementogenesis in impacted teeth, highlighting differences in the types of cementum formed.

Background and objective Enamel matrix derivatives (EMD) are biomaterials extracted from porcine dental germs. They consist of amelogenins (90%), ameloblastine, enamelin, and amelotin. New evidence has shown that all these proteins can be absorbed onto hydroxyapatite crystals and collagen fibers on the root surface of teeth and initiate regeneration of root cementum as well as stimulate periodontal cell proliferation.
