Imaging analysis of 1 138 supernumerary teeth by using cone-beam computed tomography.

Objectives: This study aims to analyze and summarize the characteristics of supernumerary teeth by using cone-beam computed tomography (CBCT).

Methods: A total of 718 patients with 1 138 supernumerary teeth were retrospectively collected. Age, gender, number, location, morphology, eruption status, and accompanying symptoms of the supernumerary teeth were statistically analyzed.

VIRMA promotes the progression of head and neck squamous cell carcinoma by regulating mRNA and m6A levels.

Head and neck squamous cell carcinoma (HNSCC) is a globally prevalent and lethal cancer form which precise mechanisms remain incompletely understood. Increasing evidence suggests that N6-methyladenosine (m6A) plays a crucial role in cancer progression. This study aimed to explore the biological function of m6A modification and vir-like m6A methyltransferase associated (VIRMA) in HNSCC.

Inducing differentiation of human dental pulp cells toward acinar-lineage.

Objective: To induce acinar-differentiation from human dental pulp cells for potential application in aiding treatment of dry-eye syndromes.

Method: Human dental pulp cells were co-cultured with human submandibular gland acinar cells using a transwell construction for 2 weeks. The two populations of cells were physically separated while chemical and biochemical components can be exchanged.

Concentrated growth factor inhibits UVA-induced photoaging in human dermal fibroblasts via the MAPK/AP-1 pathway.

Ultraviolet (UV) radiation-induced photoaging is one of the contributors to skin aging. UV light triggers oxidative stress, producing a large number of matrix metalloproteinases (MMPs) and degrading the extracellular matrix in skin cells, thereby causing a series of photoaging symptoms. Concentrated growth factor (CGF) is a leukocyte- and platelet-rich fibrin biomaterial that plays a protective role in the occurrence and development of skin photoaging.

Concentrated Growth Factors Can Inhibit Photoaging Damage Induced by Ultraviolet A (UVA) on the Human Dermal Fibroblasts In Vitro.

BACKGROUND Photoaging is the main cause of extrinsic skin aging. Daily exposure to ultraviolet A (UVA) accelerates the process of photoaging. The present study aimed to understand the role of concentrated growth factors (CGF) on UVA irradiated human skin cells.

Effect of Xylosyltransferase-I Silencing on Implanting Growth of Salivary Pleomorphic Adenoma.

BACKGROUND Salivary pleomorphic adenoma is one of the most common salivary gland tumors. It has a relatively high tendency to recur and a high risk of malignant transformation. The present study aimed to study the effect of XT-I gene silencing on the implanting growth of salivary pleomorphic adenoma.

Morphological Observation on Critical-Sized Cranial Defect Repaired by Icariin and Autologous Concentrate Growth Factors in Rabbits.

BACKGROUND Morphological changes repaired by icariin and autologous concentrate growth factors (ACGF) in critical-sized cranial defect were observed and their promoting effects were investigated. MATERIAL AND METHODS Seventy-two New Zealand white rabbits weighing 1.8~2.

The relationship between proteoglycan inhibition via xylosyltransferase II silencing and the implantation of salivary pleomorphic adenoma.

Objective: To study the relationship between proteoglycan inhibition and the implantation of salivary pleomorphic adenoma (SPA).

Methods: SPA fresh tissue was primitively cultured and identified. The Ad-shRNA-XT-II adenovirus vector was constructed and transfected into SPA cells to silence the XT-II gene.

[Rapid canine distalization through distraction of the periodontal ligament after reducing interseptal bone resistance].

Objective: To investigate the effect of rapid canine distalization through distraction of the periodontal ligament after reducing interseptal bone resistance.

Methods: Twenty canines in 11 patients who needed first premolar extractions were involved. A tooth-borne, custom-made distractor was bonded right after the first premolar extraction and the interseptal bone resistance reduction.

[Study on effect of snore guard to upper airway structure of normal occlusion people by magnetic resonance imaging].

Objective: To investigate the imagery changes of the upper airway and the surrounding soft tissues of local adults with non-apnea who used snore guard and to provide experimental data for the clinical diagnosis and treatment of obstructive sleep apnea syndrome (OSAS).

Methods: Thirty students with non-apnea from Hebei medical university were chosen, and magnetic resonance imaging (MRI) was used to measure the changes of the upper airway and the surrounding soft tissues after snore guards were used. SPSS 105 software was used to analyze statistically.

[The effect of hyaluronic acid external film on rats wound healing].

Objective: To observe the effect of an external film of hyaluronic acid (HA) on the rats wound healing.

Methods: Forty-eight SD rats were randomly separated into eight groups of 6 rats each. Bilateral dorsal cuts were performed on each rat, left wound was used as the experiment with HA external film and right wound was used as the control only with normal saline.
