Effect of Bleaching Treatments on the Mechanical Properties of the Dentin Matrix and on Collagen Biodegradation by Endogenous Protease.

This study evaluated the mechanical properties of demineralized dentin matrix submitted to different bleaching treatments, as well as the changes in mass and collagen biodegradation brought about by endogenous protease. Dentin collagen matrices were prepared to receive the following treatments (n=12): no bleaching treatment (C-control), 10% carbamide peroxide (CP-Opalescence PF, Ultradent, South Jordan, UT, USA) 10%/8 hours/ day/14 days, and 40% hydrogen peroxide (HP-Opalescence Boost, Ultradent), 40 minutes per session/3 sessions. The dentin matrices were evaluated for elastic modulus and mass before and after treatments and ultimate tensile strength after treatments.

Design, In Vitro Evaluation and In Vivo Biocompatibility of Additive Manufacturing Three-Dimensional Printing of β beta-Tricalcium Phosphate Scaffolds for Bone Regeneration.

The reconstruction of bone deficiencies remains a challenge due to the limitations of autologous bone grafting. The objective of this study is to evaluate the bone regeneration efficacy of additive manufacturing of tricalcium phosphate (TCP) implants using lithography-based ceramic manufacturing (LCM). LCM uses LithaBone TCP 300 slurry for 3D printing, producing cylindrical scaffolds.

Juvenile Recurrent Parotitis: Video-Documented Sialendoscopy.

Juvenile recurrent parotitis (JRP) is characterised by recurrent episodes of painful parotid swelling in children. JRP is the second most common cause of parotitis in childhood, behind only paramyxovirus. The prevention of recurrent attacks represents the most dramatic and serious aspect of this pathology.

Sialendoscopy approach in treating juvenile recurrent parotitis: a systematic review.

Background: Juvenile recurrent parotitis (JRP) is characterized by recurrent episodes of painful parotid swelling in children. The purpose of this systematic review was to determine the diagnostic and therapeutic effectiveness of sialendoscopy in children affected by JRP.

Methods: A systematic literature search was performed in PubMed, EMBASE, Scopus and the Cochrane Library until April 2022, without language restrictions or specified start date.

Role of Dentistry in Humanitarian Projects: Knowledge and Perspective of Future Professionals on the World of Volunteering in Spain.

Non-governmental organizations (NGOs) in dentistry seek to promote the improvement on oral health in the most disadvantaged regions. The objective of this study is to identify the level of knowledge, expectations, and motivations that dental school students have about volunteering in dentistry, as well as to evaluate possible differences in these variables depending on their level of dental training. During the month of September 2022, a voluntary and anonymous online survey was carried out among all the students at the Dentistry School of Oviedo University.
