OBJECTIVES To determine the effect of the combined use of epigallocatechin-3-gallate (EGCG) and ethanol-wet bonding (EWB) on resin-dentin bonds. METHODS Sixty molars were sectioned, polished, and randomly divided into six groups (n=10) according to the following pretreatments: group 1, water-wet bonding (WWB); group 2, WWB with 0.02% (w/v) EGCG; group 3,(More)
Desensitizing agents are frequently applied to sensitive teeth and may affect subsequent resin bonding. The current study aimed to evaluate the bonding performance of two self-etch adhesives containing functional monomers to dentine pretreated with three new calcium-containing desensitizers. No desensitizer was applied in the control group. Groups 1, 2, and(More)
OBJECTIVES To fabricate a nanohydroxyapatite/mesoporous silica nanoparticle (nHAp@MSN) biocomposite and investigate its effectiveness on dentinal tubule occlusion, acid-resistant stability, and microtensile bond strength (MTBS). METHODS The nHAp@MSN biocomposite was synthesized and characterized by X-ray diffraction (XRD), Fourier transform infrared(More)
Human dental pulp cells (HDPCs) play a crucial role in dental pulp inflammation. Pannexin 3 (Panx3), a member of Panxs (Pannexins), has been recently found to be involved in inflammation. However, the mechanism of Panx3 in human dental pulp inflammation remains unclear. In this study, the role of Panx3 in inflammatory response was firstly explored, and its(More)
PURPOSES To evaluate (1) the effect of a desensitizing paste containing 8% arginine and calcium carbonate on the microtensile bond strength between dentin and etch-and-rinse adhesive systems; and (2) to examine the dentin tubules occlusion quantitatively. METHODS 48 freshly extracted intact human mandibular third molars were divided randomly into three(More)
OBJECTIVES To compare the effects of four commonly used artificial ageing methods (water storage, thermocycling, NaOCl storage and pH cycling) on the degradation of adhesive-dentine interfaces. METHODS Fifty molars were sectioned parallel to the occlusal plane, polished and randomly divided into two adhesive groups: An etch-and-rinse adhesive Adper(More)
Grassland fire is a serious and common disaster in Inner Mongolia, China and it is a kind of extremely complex natural phenomena influenced by various factors. The design aims to simulate the fire trend based on GIS and scientific grassland fire spread model and finally provides assistant decisions. The system will be used in Inner Mongolia Emergency(More)
OBJECTIVES To evaluate the effects of different application sequence of calcium-containing desensitising pastes on bonding effectiveness and tubule occlusion during etch-and-rinse (E&R) adhesive restoration. METHODS Seventy molars were sectioned parallel to the occlusal plane, polished and randomly divided into seven groups (n=10). Group 1 was etched with(More)
The grassland makes a significant contribution to the economy of Inner Mongolia. However, the grassland fire, which causes a great damage to the animal husbandry and threatens the properties securities of people in the pastoral area, is becoming an important interference factor to the steady development of grassland animal husbandry. The article, which(More)
The bonding restoration has become an important clinical technique for the development of dental bonding technology. Because of its easy operation and the maximum preservation of tooth tissues, bonding repair is widely used in dental restoration. The recent multi-mode universal adhesives have brought new progress in dental bonding restoration. In this(More)
