Cone Beam CT Evaluation of the Prevalence and Characteristics of the Retromolar Canal
Conclusions: The results of the present investigation showed that the RMC was a common anatomic structure. Therefore, because of its clinical significance, it is highly recommended that dental practitioners consider this structure in pre-surgical evaluations of the region in order to avoid related complications.  (Source: Journal of Dental Biomaterials)

The Effect of Two Types of Denture Adhesive on the Satisfaction Parameters of Complete Denture Wearers
Conclusions: The study clarified that applying denture adhesives (both types) markedly improved the satisfaction rate in complete denture wearers without any complications. Further studies on a larger group is suggested to determine which kind of denture adhesive is more effective and if there is any possible side effects that restrict the use of such substances.

Cytokeratin: a Shortcut to Diagnose Spindle Cell Carcinoma
A relatively rare subtype of squamous cell carcinoma (SCC) is spindle cell carcinoma (SPCC). It is composed of epithelium-derived spindle cells arranged in sheets with mesenchymal properties and small, hardly detectable regions of SCC, challenging its definite diagnosis. We encountered five cases of SPCC. In case one, chronic inflammation and subepithelial blister with leukoplakia was found 5 years before our examination. And later, exophytic features, keratotic papules and scar with elevated margins was seen on lateral border of the tongue. In case two, three and four, an abnormal soft tissue elevations were examined, and...

Investigating the Effect of C-Factor and the Method of Bulk-Fill and Nanohybrid Composites Placement on Their Microtensile Bond Strength to Dentin
Conclusion: Considering the research constraints of this laboratory study, bulk-fill composites can be cured well in a 4-mm depth. However, it is advised to use the incremental method in cavities with high C-factors due to the high stress caused by the polymerization shrinkage. (Source: Journal of Dental Biomaterials)

Factors Affecting Oral Hygiene and Tooth Brushing in Preschool Children, Shiraz/Iran
Conclusions: The compressive strength of all cements did not necessarily increase after 24 h and varied depending on the materials. There was a strong reverse correlation between sorption and CS values after both 1 and 24 h immersion. It may be practical for clinician to use those cements with the less sorption / solubility and more stable compression strength over time.Key words:  Child, Inadequate Tooth Brushing, Oral Hygiene, Oral Hygiene Index, Risk Factors  (Source: Journal of Dental Biomaterials)

Effect of Different Irrigation Solutions on the Colour Stability of Three Calcium Silicate-Based Materials
Conclusions:The contact of wMTA, CEM cement, and Biodentine with CHX should be avoided because this leads to severe discoloration. Contact with sodium hypochlorite also leads to discoloration of wMTA and CEM cements.   Among of the three tested materials, wMTA showed the highest discoloration after contact with NaOCl, CHX, and EDTA.Key words:  Biodentine, Calcium Enriched Mixture, Discoloration, Mineral Trioxide, Aggregate, Spectrophotometric Analysis  (Source: Journal of Dental Biomaterials)
