Collagen is the fundamental protein forming the connective tissues matrix, improves the ability of keratinocytes to migrate to sites that require rebuilding of the damaged epidermis, is one of the component of dressings used to accelerate wound healing. Because of the potential risk of the presence of pathogenic prions in bovine collagen, part of collagen dressings is formed on the basis of porcine collagen. Currently, a least of an immunogenic form of collagen is atelocollagen, which is subjected to enzyme-treated collagen, in which the terminal amino acids are removed from the collagen. It is assumed that in the near future atelocollagen will be used also as a carrier for drugs which support the healing processes.

NCK1 antisense RNA 1 (NCK1-AS1) exerts pro-fibrosis property in oral mucosa through modulation of miR-137/NCK1 axis.
J Dent Sci
January 2025
Department of Emergency Medicine, Chi Mei Medical Center, Tainan, Taiwan.
Background/purpose: Oral submucous fibrosis (OSF) is a premalignant condition of the oral cavity, and its pathogenesis remains largely unknown. A multitude of non-coding RNAs are aberrantly expressed in OSF, and their implication for the development of OSF is a matter meriting investigation.
Materials And Methods: The functional role of long non-coding RNA NCK1-AS1 in myofibroblast activation of fibrotic buccal mucosal fibroblasts (fBMFs) derived from OSF tissues was assessed.
Optimized human dedifferentiated fat cells from the buccal fat pad-derived osteoinductive extracellular vesicles promote osteoblast differentiation.

Second Department of Oral and Maxillofacial Surgery, Osaka Dental University, Osaka, Japan.
Background/purpose: Bone reconstruction in the maxillofacial region typically relies on autologous bone grafting, which presents challenges, including donor site complications and graft limitations. Recent advances in tissue engineering have identified highly pure and proliferative dedifferentiated fat cells (DFATs) as promising alternatives. Herein, we explored the capacity for osteoblast differentiation and the osteoinductive characteristics of extracellular vesicles derived from DFATs (DFAT-EVs).

J Dent Sci
January 2025
School of Dentistry and Institute of Oral Medicine, National Cheng Kung University, Tainan, Taiwan.
Background/purpose: The efficacy of riboflavin-ultraviolet-A (RF-UVA) treatment in crosslinking collagen and improving dentin bonding has been proven. However, biodegradation of the hybrid layer may compromise the bonding. The purpose of this study was to evaluate different RF-UVA treatments regarding their ability to preserve dentin bonding from enzymatic digestion.

Department of Dentistry, College of Dentistry, National Yang Ming Chiao Tung University, Taipei, Taiwan.
Background/purpose: Temporomandibular joint (TMJ) arthritis causes inflammation and degradation of the mandibular condylar cartilage and subchondral bone. Complete Freund's adjuvant (CFA) and collagen-induced arthritis (CIA) are models for studying TMJ arthritis. While micro-computed tomography (micro-CT) is crucial for three-dimensional (3D) bone analysis, it has limitations in imaging nonmineralized tissues.

Department of Oral Surgery, Faculty of Odonto-Stomatology, University of Medicine and Pharmacy at Ho Chi Minh City, Ho Chi Minh City, Viet Nam.
Background/purpose: Autologous dentin materials are among the most promising bone substitutes for preventing osseous defects on the distal side of the lower second molar. This study aimed to investigate the effects of autologous demineralized dentin matrix on postoperative complications and wound healing after lower third molar surgery.
Materials And Methods: Thirteen patients with bilateral symmetrical lower third molars participated in this split-mouth randomized clinical trial.
