Article Synopsis
- The study aimed to compare the effects of removable dentures created through 3D printing versus traditional casting methods on patients' perceptions and comfort.
- It involved 80 patients with specific dentition issues, analyzing factors like intraoral tenderness, chewing efficiency, and overall satisfaction after two months of wearing the dentures.
- Results showed that 3D printed dentures had fewer tender points and higher chewing efficiency, leading to significantly better subjective feelings and satisfaction compared to those made by plaster casting.
[An evaluation of fiber reinforced composites veneer in anterior esthetic restoration].

Article Synopsis
- The study investigates the effectiveness of fiber reinforced composite veneers for repairing discolored and defective anterior teeth compared to traditional porcelain veneers.
- Twenty porcelain and 20 fiber reinforced composite veneer samples were tested for their bonding strength after preparation and treatment, revealing significant differences in performance.
- Results indicated that fiber reinforced composites exhibited a higher compressive strength at the bonding interface, suggesting they are more advantageous for repairs than porcelain veneers, which cannot be repaired once damaged.
[3-D reconstruction of the maxillary central incisor by digital camera].
Shanghai Kou Qiang Yi Xue
February 2009
Purpose: To evaluate the role of digital camera in reconstruction of 3-D solid model of the maxillary central incisor.
Methods: Photographs of each section of the maxillary central incisor were taken with digital camera, then the 3-D model was reconstructed with photoshop software and 3DMAX software.
Results: The precise 3-D solid model of the maxillary central incisor was successfully reconstructed.
[Characteristics of free Ca2+ distribution in cultured osteoclast-like cells].
Hua Xi Kou Qiang Yi Xue Za Zhi
February 2006
Article Synopsis
- The study aimed to analyze how free calcium ions (Ca2+) are distributed in osteoclast-like cells grown on glass.
- Researchers used laser scanning confocal microscopy and a fluorescent probe to visualize and measure free Ca2+ levels within the cells.
- Results showed that free Ca2+ concentration was higher in the center of the cells compared to the edges, indicating that the uneven distribution of Ca2+ could play a role in how these cells regulate their functions.
[Clinical evaluation of masticatory function of implant supported dentures in partially edentulous patients].
Hua Xi Kou Qiang Yi Xue Za Zhi
October 2005
Objective: To evaluate the masticatory efficiency of implant supported dentures in partially edentulous patients and the patients' satisfaction on masticatory function.
Methods: The masticatory efficiency of implant supported dentures of 22 patients were tested. The questionnaire of the patients' satisfaction about masticatory function had also been collected.
[Observation of osteoclasts on the root surface during human deciduous teeth resorption].
Hua Xi Kou Qiang Yi Xue Za Zhi
August 2004
Objective: To observe osteoclasts on the resorbing surface of human deciduous teeth.
Methods: After fixing the collected deciduous teeth, we prepared the tooth slices without decalcification, treated them with HE and TRAP dyestuff, and observed the osteoclasts under light and scanning electron microscope.
Results: There were large quantity of various forms of overlapping and huge osteoclasts with many nuclei and silk-like protuberances on the resorbing surface of deciduous teeth.
[Investigation of the expression of calcitonin receptor mRNA in human osteoclasts on deciduous teeth].
Hua Xi Kou Qiang Yi Xue Za Zhi
June 2004
Objective: To investigate the expression of calcitonin receptor mRNA in the osteoclasts of the resorbing deciduous teeth.
Methods: After fixing the collected deciduous teeth, toluidine blue was performed and tartrate-resistant acid phosphatase (TRAP) staining was used to identify the osteoclasts on the resorbing surface of human deciduous teeth and in situ hybridization of calcitonin receptor mRNA to show its existence.
Results: There were a number of TRAP positive osteoclasts on the root surface which showed the expression of calcitonin receptor mRNA.
