Objective: To evaluate the expressions of nuclear factor nB (NF-nB p65), inducible nitric oxide synthase enzyme (iNOS), and vascular endothelial growth factor (VEGF) in relation to angiogenesis (microvessel density, MVD) and clinical outcomes in adenoid cystic carcinoma (ACC) of salivary glands. Methods: Immunohistochemical staining was used to quantify the protein expression levels of NF-nB p65, iNOS, and VEGF in 80 surgically resected ACCs and 20 normal salivary tissues. In all cases of ACCs, MVDwas evaluated by counting CD34-reactive endothelial cells or endothelial cell clusters. Results: The nuclear localization of NF-nB p65 was only detected in ACC cells. Both iNOS and VEGF staining activities in ACCs were more significant than those in normal gland tissues (P<0.01). MVD had significant correlations with NF-nB p65, iNOS, and VEGF expressions (P<0.01). In three histologic types of ACCs, the NF-nB, iNOS, VEGF expressions, andMVDwere significantly higher in solid type than in cribriform and tubular types (P<0.01).The NF-nB, iNOS, VEGF expressions, and MVD were significantly correlatedwith clinical stage, tumor size, vascular invasion, recurrence, and metastasis (P<0.05). Multivariate analysis showed NF-nB, iNOS and VEGF expression, MVD, solid histotype, and perineural invasion had an independent prognostic effect on overall survival. Conclusion: The expressions of NF-nB p65, iNOS, and VEGF were related with MVD. Clinical outcomes raised the possibility that the overexpression of these cytokines might contribute to tumor angiogenesis and have prognostic value in ACCs.

The purpose of this study was to evaluate the effect of a bi-annual professional application of acidulated phosphate fluoride (APF) foam on caries increment in the primary dentition over a two-year period in the People's Republic of China. In a double-blind, cluster-randomized, placebocontrolled trial, 392 children aged 3-4 years from 15 classes were randomly assigned to two groups on a school class basis. The experimental group (8 classes) received a bi-annual APF foam application, and the control group (7 classes) received the placebo. The mean increment of dmfs in the experimental group was 24.2% lower than that in the control group (p<0.05). The significant caries reduction was observed on approximal surfaces in the experimental group compared with the control group (p<0.01), but there were no differences on occlusal surfaces (p>0.05). A bi-annual professional application of APF foam was effective in reducing the increment of dental caries in the primary teeth.

【期刊论文】Defects in ProTaper S1 instruments after clinical use: fractographic examination

Aim To investigate the mode of failure of a brand of nickel-titanium instruments separated during clinical use, by detailed examination of the fracture surface. Methodology A total of 122 ProTaper S1 instruments were discarded from an endodontic clinic at a stomatological school in China over a period of 17 months; 28 had fractured. These fractured instruments were ultrasonically cleaned, autoclaved and then examined under a scanning electron microscope. From the lateral view the fracture was classified into 'torsional' or 'flexural'. The specimens were then re-mounted and the presence of characteristics of shear failure and fatigue striations was recorded under highpower view of the fracture surface. The difference in the mean lengths of fractured segment between the shear and fatigue groups was compared using Student's t-test. Results Twenty-seven separated instruments were available for analysis. Under low-power magnification, only two fell into the category of 'torsional failure when examined laterally; the others appeared to be 'flexural'. Close examination of the fracture surface revealed the presence of fatigue striations in 18 specimens. Nine instruments (including the two putative 'torsional' failures above) fell into the shear fracture group, in which fatigue striations were absent or characteristics of shear failure of the material were found. The mean length of fractured segments resulting from fatigue failure (4.3

Objective. To evaluate the influence of various factors on the success or failure of attempts to remove fragments of separated NiTi instruments from root canals. Study design. Instrument removal attempts were undertaken on 72 teeth with a separated NiTi instrument using a variety of techniques and armamentarium. Factors including type of tooth, degree of root canal curvature, location of fragment in relation to the root canal curvature, and radiographic length of fragment were analyzed. A success of treatment was defined as removal or complete bypassing of the fragments. Results. The overall success rate was 53%. The success rate for ProFile fragments was 41% and for the NiTi K-file 60%. The success rate in maxillary teeth was higher than that in mandibular teeth. Of 52 instruments in molars, 28 were successfully removed or bypassed. Of the 12 fragments in premolars, only 2 were removed. All 8 cases in anterior teeth were retrieved completely. When the fragment was localized before the curvature, complete removal was achieved. When the fragments were located at and beyond the curvature, the success rates were 60% and 31%, respectively. In canals with a slight, moderate, and severe curvature, the success rates were 100%, 83%, and 43%, respectively. In general, the longer the fragment, the greater the chance for successful removal or bypass. Conclusions. Favorable factors for removal of separated NiTi fragments are straight root canals, anterior teeth, localization before the curvature, fragments longer than 5 mm, and hand NiTi K-file.
