BACKGROUND:It has been found that the compressive strength and flexural strength of nano-hydroxyapatite combined with light-cured resin matrix can neet the requirements of dental restorative materials. OBJECTIVE:To detect the cytotoxicity of nano-hydroxyapatite/composite resin, and to analyze its effects on the dental restoration. METHODS:In vitro test:passage 5 periodontal ligament fibroblast-like cel s and L-929 cel s suspensions were cultured in the 10%, 50%, 100%of nano-hydroxyapatite/composite resin extracts, respectively, and fresh maintenance medium functioned as negative control group. Absorbance values were detected within 7-day culture. In vivo repair test:57 cases with tooth defect were enrol ed containing 37 males and 20 females aged from 15 to 31 years old, and al were subjected to nano-hydroxyapatite/composite resin treatment. A 3-year fol ow-up was undergone to detect the completeness, marginal adaptation and color matching of the restoration, as wel as the periodontal probing depth, sulcus bleeding index, tooth mobility, dental plaque index, gingival crevicular fluid and aspartate aminotransferase level. RESULTS AND CONCLUSION:In vitro test results showed that the different concentrations of nano-hydroxyapatite/composite resin extracts had no effects on both periodontal ligament fibroblast-like cel s and L-929 cel s. In vivo repair test results found that after 3 years of fol ow-up, the periodontal probing depth, sulcus bleeding index, tooth mobility, dental plaque index, gingival crevicular fluid and aspartate aminotransferase level of patients were significantly decreased than those before repair (P<0.05), but the alkaline phosphatase level revealed no significant change (P>0.05). Unfortunately, three cases with incomplete restoration, four cases with color mismatching, and three cases with the inadaptable edge occurred. To conclude, the nano-hydroxyapatite/composite resin holds good biocompatibility and no cytotoxicity, which can maintain a good periodontal health condition in the dental restoration.

BACKGROUND: Fluorine used for light-cured fluorine-containing resin can reduce and prevent dental caries, as well as play a long-term effect against tooth decay. However, there are rare reports on the composite preparation and performance.OBJECTIVE: To study the preparation and performance of the light-cured fluorine-containing resin. METHODS: Triethylamine as a catalyst, bisphenol A, bisphenol S, glycidyl methacrylate, trifluoroacetic anhydride and inorganic fillers (modified silicon dioxide, hydroxyapatite or titanium dioxide at mass fraction of 5％, 10％, 15％, 20％)were mixed to prepare the light-cured fluorine-containing resin. Then, the tensile strength, bending modulus,polymerization conversion and water of the composites were tested, and the morphology of the resin was observed under transmission electron microscope.RESULTS AND CONCLUSION: At the same mass fraction, the tensile strength was highest in the titanium dioxide group, higher in the hydroxyapatite group, and lowest in the silicon dioxide group (P < 0.05). At the same mass fraction, there was no difference in the bending modulus between the titanium dioxide group and the hydroxyapatite group (P > 0.05), while the bending modulus in the silica group was significantly higher than that in the other two groups (P < 0.05).At the same mass fraction, the polymerization conversion of the composite resin was higher in the titanium dioxide group than the hydroxyapatite and silicon dioxide groups (P < 0.05), but there was no difference between the latter two groups (P > 0.05). With the increasing of mass fraction, the water absorption of the composite resin kept an increasing trend.Under the transmission electron microscope, the fracture surface of the silicon dioxide group was relatively flat, and the resin body exhibited good biocompatibility with the filler; in the hydroxyapatite group, the fracture surface was rough with obvious ups and downs, and the biocompatibility between the resin body and the filler was relatively poor; in the titanium dioxide group, the fracture surface was layered and the filler settled in the resin body, and moreover, titanium dioxide particles were deposited on the bottom of the resin, resulting in larger voids and filler particles as well as poor biocompatibility. To conclude, the light-cured fluorine-containing resin has good mechanical properties, curable properties and absorption rate.

The penal stipulation to the subject range about crime of illegal medical practice is too narrow,and there is also a great deal of contradictory regulation between Criminal Law and Practicing Physicians Law so it can not achieve the legislation goal.It is essential to revise the 1st section of "Criminal law "336th in order to expand the subject range and standardize the medical service market of our country.
