Evaluating the accuracy of Kvaal ’s method for age estimation in a selected Iranian population
Conclusions: For young adults, the M and W-L variables anticipated accuracy rates lower than those of Kvaal ’s reference study which were within an acceptable threshold for forensic application (SEE<10 years). Therefore, the two variables and not formulas are proper measurements for forensic age estimation in Iranian young adults. However, underestimation was predominant for the middle age and old age participants. (Source: Journal of Dental Biomaterials)

Vital Pulp Therapy of an Immature Traumatized Permanent Tooth with External Inflammatory Root Resorption, a Case Report
External inflammatory root resorption is a serious complication of a dentaltrauma, which leads to progressive loss of the tooth structure and destruction ofperiodontal tissues. Therefore, it represents a challenge in endodontic practiceespecially in cases of young children with incomplete root development.Vital pulp therapy (VPT) is an appropriate technique in the managementof immature permanent teeth with partial pulp necrosis. This case reportdescribes the outcome of a successful VPT in an immature traumatizedpermanent tooth with concurrent associated partial necrosis and external rootresorption limited to the coronal pa...

Efficacy of Endodontic Files with Different Metallurgical Characterization in Removing Root Canal Filling Material
Conclusions: None of the tested files could completely remove the RCFM.Under the limitation of this study, the files with shape memory (Reciproc andPTUR files) exhibited better performance than the files with reduced shapememory (Reciproc Blue) and controlled memory (HyFlex CM) in removingthe RCFM.

Recent Advances and Future Perspectives for Reinforcement of Poly(methyl methacrylate) Denture Base Materials: A Literature Review
Poly(methyl methacrylate) (PMMA) is the most common material used to fabricate complete and partial dentures. Despite its desirable properties, it cannot fulfill all mechanical requirements of prosthesis. Flexural fatigue due to repeated masticatory and high-impact forces caused by dropping are the main causes of denture fractures. In the past, different reinforcing agents such as rubbers, macro fibers, and fillers have been employed to improve the mechanical properties of denture base resins. Development of Nano dentistry has introduced new approaches for reinforcement of dental materials. Interest in nanostructure materi...

Influence of Er,Cr:YSGG Laser Surface Treatments on Micro Push-Out Bond Strength of Fiber Posts to Composite Resin Core Materials
Conclusions: The beneficial effect of Er,Cr:YSGG laser application could not be confirmed based on the results of thisin vitrostudy. Er,Cr:YSGG laser could not significantly enhance the bond strength values. However, the 1.5W laser statistically decreased micro push-out bond strength in the Exacto fiber posts.

Evaluation of Antibacterial Properties of Dental Adhesives Containing Metal Nanoparticles
Conclusions:These metal-based nanoparticles exhibited dose-dependent bactericidal activities. The Ag nanoparticles had higher antibacterial activity compared to the TiO2 nanoparticles. Incorporation of these nanoparticles into dental adhesives is a promising way to reduce the risk of secondary caries. However, further clinical evaluations should be performed.
