Longitudinal Study of Scar Hyperplasia Formation Following Cleft Lip Wound Healing.

The purpose of this study was to observe the hyperplasia trend of scar after the cleft lip surgery in a rabbit animal model, and determine the time-point of the highest hypertrophic degree of scar after cleft lip repair. Forty New Zealand white rabbits from the same offspring were used to establish a cleft lip wound healing model using Millard surgery procedure. The scar volumes were measured and granulation tissues were observed visually in the 2, 3, 4, and 5 weeks after operation.

The relationship between maternal corticosteroid use and orofacial clefts-a meta-analysis.

The aim was to evaluate the relationship between maternal corticosteroid use during first trimester of pregnancy and risk of orofacial clefts (OC). The overall findings showed a certain association between maternal corticosteroid use and occurrence of OC, compared with non-users (OR=1.16 [95% CI: 1.

Dhcr7 Regulates Palatal Shelf Fusion through Regulation of Shh and Bmp2 Expression.

The aim of this study was to investigate the effect of the 7-dehydrocholesterol reductase (Dhcr7) gene and identify signaling pathways involved in regulation of embryonic palatogenesis. The expression of Dhcr7 and its protein product were examined during murine normal embryonic palatogenesis via a reverse transcription polymerase chain reaction (RT-PCR) and Western blot (WB). RNA interference (RNAi) technology was used to inhibit Dhcr7 expression in a palatal shelf culture in vitro.

Botulinum Toxin Type A and the Prevention of Hypertrophic Scars on the Maxillofacial Area and Neck: A Meta-Analysis of Randomized Controlled Trials.

Background: The purpose of the meta-analysis was to evaluate the efficiency of therapeutic botulinum toxin type A (BTX-A) in the prevention of maxillofacial and neck scars.

Methods And Findings: Information came from the following electronic databases: Medline, PubMed, Cochrane Library, and EMBASE (time was ended by August 31, 2015) to retrieve RCTs evaluating the effect of the BTX-A for hypertrophic scar on the maxillofacial or neck. All languages were included as long as they met the inclusion criteria.

The caries prevalence of oral clefts in eastern China.

Little information is available concerning the prevalence of caries among patients with oral clefts in Eastern China. Consecutive patients aged 6-18 with oral clefts were recruited. Patients were stratified into 2 groups according to their ages, namely Group I with aged 6-12 and Group II with aged 13-18.

Evaluation of Bone Height and Bone Mineral Density Using Cone Beam Computed Tomography After Secondary Bone Graft in Alveolar Cleft.

The purpose of this study was to assess the optimal timing of subsequent dental implant placement and orthodontics after alveolar bone grafting (ABG) in patients with unilateral complete clefts of the alveolar process. Iliac bone graft surgery was performed on 60 patients. Bone mineral density (BMD) and height of the ABG areas were assessed using cone beam computed tomography at 3 and 6 months postoperatively.

Intermittent Stretching and Osteogenic Differentiation of Bone Marrow Derived Mesenchymal Stem Cells via the p38MAPK-Osterix Signaling Pathway.

Aims: The relationship between the p38MAPK signaling pathway and osterix in osteogenic differentiation of BMMSCs subjected to intermittent stretching was investigated.

Methods: BMMSCs derived from C57BL/6J mice were divided into the following groups: 1) control, 2) stretch, and 3) SB203580+stretch (SB203580 is a p38MAPK signal pathway inhibitor). BMMSCs were exposed to an intermittent mechanical strain of 0.

The effect of p38MAPK on cyclic stretch in human facial hypertrophic scar fibroblast differentiation.

Hypertrophic scars (HTS), the excessive deposition of scar tissue by fibroblasts, is one of the most common skin disorders. Fibroblasts derived from surgical scar tissue produce high levels of α-smooth muscle actin (α-SMA) and transforming growth factor-β1 (TGF-β1). However, the molecular mechanisms for this phenomenon is poorly understood.

[Establishment of palatal organ culture model of C57BL/6J mouse embryos in vitro].

Purpose: To establish palatal organ culture model of C57BL/6J mouse embryos in vitro and provide platform for study of embryo palatal development.

Methods: The mouse palatal shelves were harvested under sterilization from a female mouse of gestation day(GD) 13.5 by stereoscopic microscope and cultured in vitro.

Aspiration of two permanent teeth during maxillofacial injuries.

Aspiration of a tooth in maxillofacial injuries is a known complication necessitating prompt recognition and early treatment to minimize potentially serious and, sometimes, even fatal consequences. Here, we report a rare and unusual case in its presentation, the patient having aspirated 2 permanent teeth after maxillofacial, cervical vertebrae, and thoracic region crush injuries due to a motor vehicle accident. The diagnosis of teeth aspiration was delayed until 2 weeks after the event.

Multiple orofacial malformations in a boy who was conceived by intracytoplasmic sperm injection.

Intracytoplasmic sperm injection (ICSI) and other assisted reproductive technologies (ART) are effective treatments for infertility and are widely used at infertility clinics. Although ICSI is generally considered safe, some studies have suggested an excess occurrence of major birth defects resulting from the procedure. Here, we present a rare case of a boy with multiple orofacial malformations who was conceived by ICSI.

[An in vitro experiment on the antimicrobial effects of ethanol extract from salvia miltiorrhiza bunge on several oral pathogenic microbes].

Purpose: To study the in vitro antimicrobial activity of ethanol extract of salvia miltiorrhiza bunge on several oral pathogenic microbes.

Methods: Antimicrobial activities of ethanol extract of salvia miltiorrhiza bunge for porphyromonas gingivalis ATCC 33277, A. actinomycetes comitans ATCC 24523, Streptococcus mutans, and Lactobacillus were determined using the cup-plate method.

[Relationship between periodontal disease and rheumatoid arthritis].

Objective: To study a population of rheumatoid arthritis patients and determine the extent of periodontal disease in these patients, in order to investigate the relationship between periodontal disease and rheumatoid arthritis.

Methods: The experimental group was composed of 70 patients with rheumatoid arthritis and the control group consisted of 70 age- and gender-matched individuals without rheumatoid arthritis. The relationship between periodontal status in rheumatoid arthritis and control groups as well as the relationship between periodontal status and rheumatological findings in patients were analyzed.
