Composite-derived monomers affect cell viability and cytokine expression in human leukocytes stimulated with Porphyromonas gingivalis
Conclusions: These results show that resin monomers are toxic to PBMC in a dose-dependent manner, and may influence the local immune inflammatory response and tissue damage mechanisms via regulation of bacterial-induced IL-1 β and TNF- α secretion by PBMC. (Source: Journal of Applied Oral Science)

Challenges in measuring angles between craniofacial structures
Conclusion: Measurements of 3D angles between facial planes in a common coordinate system are reproducible and repeatable either using 3D pre-existing planes, created based on landmarks or angles between lines created from landmarks. (Source: Journal of Applied Oral Science)

Temporomandibular joint function 10-15 years after mandibular setback surgery and six weeks of intermaxillary fixation
Conclusion: Ten to fifteen years after mandibular setback surgery the patient's mandibular range of movement is good. Despite clinically recognizable symptoms, few patients reported having TMJ- or masticatory muscle-related symptoms in their daily life. (Source: Journal of Applied Oral Science)

Fatigue survival and damage modes of lithium disilicate and resin nanoceramic crowns
Conclusions: The results suggest that if debonding issues can be resolved, resin nanoceramic figures can be an alternative to posterior crowns. Although distinct, damage modes revealed potential to cause bulk fracture in both glass ceramic and resin nanoceramic crowns. (Source: Journal of Applied Oral Science)

Comparison between calcium hydroxide mixtures and mineral trioxide aggregate in primary teeth pulpotomy: a randomized controlled trial
Conclusion: CH with PEG performed better than CH with saline as capping material for pulpotomy of primary teeth. However, both combinations yielded clinical and radiographic results inferior to those of MTA alone. (Source: Journal of Applied Oral Science)

A new approach for Y-TZP surface treatment: evaluations of roughness and bond strength to resin cemen
Conclusions Therefore, the results showed that sonochemical treatment modifies the Y-TZP surface and is similar to the well-established sandblasting surface treatment regarding the strength of the bond with the resin cement. (Source: Journal of Applied Oral Science)

Effect of dental bleaching on pulp oxygen saturation in maxillary central incisors - a randomized clinical trial
Conclusions Pulp SaO2 level in maxillary central incisors was similar at baseline, reducing immediately after in-office bleaching, regardless of using desensitizing toothpaste and increasing at 30 days after dental bleaching. (Source: Journal of Applied Oral Science)

Microbial species associated with dental caries found in saliva and in situ after use of self-ligating and conventional brackets
Conclusions The orthodontic appliances break the salivary homeostasis of microorganisms involved in dental caries. The contamination pattern was different between self-ligating and conventional brackets. The In-Ovation®R present ed worse performance considering the levels of cariogenic bacterial species.

Twenty-four-month clinical performance of different universal adhesives in etch-and-rinse, selective etching and self-etch application modes in NCCL – a randomized controlled clinical trial
Conclusion GLUMA Universal and All-Bond Universal showed better results in etch-and-rinse and selective etching mode compared to the self-etch mode regarding retention. Etch-and-rinse and selective etching application modes of the current universal adhesives tended to provide better clinical outcomes considering the criteria evaluated at the end of 24-month evaluation.
