Purpose: The purpose of this study was to observe the friction and wear characteristics of dental fluorapatite glass ceramics, feldspathic porcelain and natural tooth in dry friction and saliva lubrication.

Methods: Two kinds of veneering porcelain (IPS-emaxcream and Vita vm9) coated zirconia-decorative porcelain double-layer material sample were prepared (size 20 mm × 20 mm × 4.5 mm), each group had 20 specimens.

Objective: To investigate new bone formation of alveolar augmentation with recombinant human bone morphogenetic protein-7 (rhBMP-7) expressed in prokaryocyte.

Methods: To create the model of rabbit extraction socket into which the composites of rhBMP-7 and the gelatin sponge was immediately implanted, then the samples were investigated 2, 4, 8 and 12 weeks postoperatively by gross observation, scanning electron microscope (SEM), quantitative measurement of calcium content and alkaline phosphatase (ALP) activity.

Results: There was significant difference in height of alveolar ridge absorpted between the experimental groups and the carrier control groups through gross observation.

Objective: To investigate the efficacy of S-methylisothiourea (SMT) for treatment of temporomandibular joint osteoarthrosis (TMJOA) of goats.

Methods: Nine purebred black goats were randomly devided into three groups: Normal control group, control group and experimental group. The upper compartments of both temporomandibular joint of the goats in control group and experimental group were injected with collagenase only once to induce osteoarthrosis.

Purpose: The purpose of this study was to investigate the occurrence of p53 gene mutation in salivary adenoid cystic carcinoma, the correlation between the gene and prognostic significance.

Methods: A series of salivary adenoid cystic carcinoma were studied by polymerase chain reaction and single strand conformation polymorphism (PCR-SSCP) analysis to detect p53 mutation, respectively.

Results: The result showed that p53 gene mutations in exon 5-8 were detected in 65.
