The Role of Root Canal Preparation on Apical Geometry: A Review of the Literature
The amounts of apical enlargement have been a controversial issue for a long time. The enlargement of the apical part of the canal may severely impact the endodontic prognosis. Enlargement of the apical portion to a larger size may negatively affect the ability to control the filling material during root canal obturation. In addition, an open-apex increases the risk for overfilling which has been shown to be related with decreased success rate. The retreatment of a tooth with apically enlarged canal may be even impossible. Further preparation of an apically enlarged canal may increase the risk of iatrogenic errors and also...

Bone-Borne Maxillary Expansion and Traditional Rapid Maxillary Expansion: A Systematic Review ...
Conclusion: The BBE appliances do not have any advantages over tooth-borne devices with regard to the amount of skeletal or dental expansion; however, it seems to produce less tippin g in posterior teeth. (Source: Journal of Dental Materials and Techniques)

Infantile Mandibular Fracture Treatment with Double-crossed Skeletal and Circummandibular ...
Abstract The prevalence of mandibular fracture is relatively lower in the pediatric population compared to adults. The treatment of these fractures is more challenging for oral and maxillofacial surgeons due to the concerns regarding mandible growth and the presence of developing tooth buds. According to the literature, conventional methods (e.g., soft diets or closed reduction) are more effective in the treatment of nondisplaced pediatric mandibular fractures. There are few case reports regarding the treatment of mandibular fractures in infants, which have mainly introduced new technique using double-crossed direct skele...

Is the Detection of Odontoma Always Comfortable? A Case Report
Abstract Odontomas are the most common type of odontogenic tumors, which are often discovered by routine radiographic images or after taking films to determine the main cause of the tooth failure eruption or malocclusion. The present study aimed to describe a case of misdiagnosis and similarity of foreign body density in the radiographic appearance to odontoma in a 13-year-old male.    (Source: Journal of Dental Materials and Techniques)

Evaluation of Mechanical Properties of Polyethylene ‌‌ Glycol/ Dextrane Methacrylate / ...
Conclusion: A change in the proportion of the copolymer ingredients can affect the mechanical properties and destruction rate of the substance. Due to slow degradation rate and high tensile strength, a concentration of 1/2 is more appropriate to be used as a membrane for covering bone loss.   (Source: Journal of Dental Materials and Techniques)

Comparison of the Cytotoxic Effects of Nanoparticulate and Microparticulate Calcium Sodium ...
Conclusion: Nanoparticulate and microparticulate calcium sodium phosphosilicate mouthwashes have no cytotoxicity against HGFs. Cytotoxicity of the nanoparticulate mouthwash was less than that of the microparticulate mouthwash. Also, increased proliferation of fibroblasts was noted over time in both groups of mouthwashes.   (Source: Journal of Dental Materials and Techniques)

Efficacy of Different Irrigation Systems Used To Remove Calcium Hydroxide from the Root Canal
Conclusion: Currently, there is no irrigation system that can completely remove Ca(OH)2 from the root canal in endodontics. Regarding the removal of Ca(OH)2 from root canals, the PUI technique was significantly better than EndoVac and CSI techniques. In addition, the SAF technique showed significant efficacy in the middle third of the root canals.  (Source: Journal of Dental Materials and Techniques)
