A study on the epidemiology of permanent tooth caries in juvenile group in Anhui province.
Chinese Journal of Stomatology.2005;40(5):420-422.
OBJECTIVETo survey the prevalence of dental caries and the needs for dental treatment in Anhui province.
METHODSThe survey of prevalence of dental caries in group aged 12 and 15 years in Anhui province was conducted using the non-proportional, stratified, cluster sampling method.
RESULTSDMFT in 12-year and 15-year group was 0.58 and 0.95 respectively, and permanent tooth caries prevalence rate was 30.78% and 39.78% respectively, lower than that of same age of other 11 provinces in mainland China (P < 0.01). The constituent ratio of DMFT was 90.51% (D), 2.48% (M), 7.01% (F) in 12-year group and 86.78% (D), 4.30% (M), 8.92% (F) in 15-year group.
CONCLUSIONSWhen we controlled dental caries in 19.98% 12-years crowd and 22.8% 15-years crowd of Anhui province, we will had controlled the occurrence of 80% caries too in group aged 12 and 15 years.

Evaluation of the psychosocial status of fluorosis patients in fluorosis epidemic areas.
Chinese Journal of Stomatology.2005;40(5):416-419.
OBJECTIVETo explore the psychosocial effect of fluorosis on patients in fluorosis epidemic areas.
METHODSMultistage, stratified, clustered and random sampling method was used in this survey. Totally 416 inhabitants of 12, 15 and 35-44 years of age from rural fluorosis epidemic areas in Hebei province were selected. Dental fluorosis was classified by Dean's index (DI). A total of 178 patients with different types of fluorosis were involved in a psychosocial questionnaire investigation which included six five-point subscales, including attitude to teeth, subjective well-being, life satisfaction, interpersonal or social anxiety, effect of self-esteem, impact on behavior.
RESULTSFluorosis prevalence in fluorosis epidemic areas of Xingtai in Hebei province was 71.20%, and significant difference existed among three age groups (Pearson Chi-square value = 167.51, P < 0.01). With the increase of DI score, the average value of subscale "attitude to teeth" rising, ranging from 2.58 to 3.51, and value of "subjective well-being" was also increasing, ranging from 2.35 to 2.9. Statistical difference of subscale average value was found only in these two subscales ("attitude to teeth": F = 4.787, P < 0.01; "subjective well-being": F = 2.538, P < 0.05). "Attitude to teeth" was significantly different between control group and moderate group (F = 0.52, P < 0.01) and between control group and severe group (F = 0.72, P < 0.01). While significant difference of "subjective well-being" could only be found between control group and severe group (F = 0.56, P < 0.01). According to the bivariate correlation analysis, strong correlation could be found between the degree of fluorosis and the average value of sub-scales.
CONCLUSIONSThe psychosocial impact of fluorosis on patients in fluorosis epidemic areas mainly appeared in two aspects, i.e. attitude to teeth and the perception of well-being, especially in severe group.

Chinese Journal of Stomatology.2005;40(5):412-415.
OBJECTIVETo investigate a method for the repair of tissue defect.
METHODSAllogenic acellular dermal matrixes (ADM) were implanted to full-thickness skin defects made on the dorsa of rats. Two weeks later, autologous suspended epidermal cells were transplanted on to the surface of vascularized ADM. Respectively, neoepidermis was macroscopically observed 2, 3, 5 weeks after grafting, and samples were taken to make routine paraffin sections for microscopical examination, and immunohistochemical staining for type IV collagen was also performed.
RESULTSThe vascularized ADM could support proliferation and differentiation of epidermal cells, and also could promote the formation of dermal-epidermal junction. Suspended epidermal cells in an artificial culture system in vivo could develop into mature epidermis. The reconstructed skin not only looked like the normal one in appearance in which hair was removed, but also revealed a better function.
CONCLUSIONSFull-thickness skin defect can be repaired by transplanting autologous epidermal cell suspension on to vascularized ADM.

Tissue engineering of dentin-pulp complex-like structures by human dental mesenchymal cells.
Chinese Journal of Stomatology.2005;40(5):408-411.
OBJECTIVETo establish three-dimensional culture model of human dental mesenchymal cells and bioengineer in vivo with ceramic bovine bone (CBB) and Collagraft as scaffolds.
METHODSHuman dental mesenchymal cells induced upon stimulation of bFGF and IGF-1 or TGF-beta(1) were implanted onto CBB and Collagraft containing the same kinds of growth factors respectively. Then cell/scaffold constructs were transplanted into nude mice to establish in vivo culture model of dental mesenchymal cells. Control groups were set up at the same time. After 4 weeks or 10 weeks, the implants were taken out for histological and immunohistochemical analysis.
RESULTSWithin 10-week implant tissues, typical dentin-pulp complex-like structures were generated in scaffolds containing growth factors. Human dentin sialoprotein (DSP) was expressed in the newly formed dentin. This phenomenon wasn't observed in control groups and 4-week implants.
CONCLUSIONSDentin-pulp complex-like structures could be bioengineered successfully with human dental mesenchymal cells and CBB or Collagrafts containing growth factors in nude mice.

The preliminary study of three-dimensional simulation of the craniofacial system.
Chinese Journal of Stomatology.2005;40(5):405-407.
OBJECTIVETo look for the way of three-dimensional simulation of the craniofacial system.
METHODSA three-dimensional laser scanner was used for gypsum models digitization and computed tomography scans was employed for skull reconstruction, then the data of teeth and temporomandibular joint were picked up and integrated. The ARCUS sigma system was used to record spatial mandibular movements. The data of both digital reconstruction and spatial movements were transferred into one coordinate system. The software for three-dimensional simulation was programmed.
RESULTSThe preliminary program could be used to analyze static and dynamic occlusion and gnathic relations, to check the contact points and to show from various visual angles and slices. The occlusal plane, curves, and helical axis were initially defined and displayed.
CONCLUSIONSUsing available instruments and methods, we developed the primary edition for three-dimensional simulation of the craniofacial system. However, it is far from a mature system and there is still plenty of work to be done.

A histological study of three-dimensional external zygomatic suture distraction osteogenesis.
Chinese Journal of Stomatology.2005;40(5):402-404.
OBJECTIVETo explore the histological change in suture of zygomatic bone for the zygomatic suture direct distraction osteogenesis.
METHODSThe zygomatic bone was distracted by 3-D external distraction appliance without osteotomy. The specimens were taken 1, 3, 5 and 8 weeks after, and then examined histologically and compared with the blank contralateral side.
RESULTSThere were lots of fibroblasts, osteoblasts and capillary vessels in the distracted suture tissues one week after distraction, and the fibers were observed to connect the sides of suture and arranged orderly. The surfaces of the expanded suture were irregular. Bone formation was active in the expanded side. The bone trabeculae were mature and oriented in the direction of distraction in the distracted sides at 3 weeks. A great amount of new woven bones were found in 5-week specimen. New bones were formed completely 8 weeks after the distraction.
CONCLUSIONSNew bone formed rapidly in the distracted side of zygomatic bone under suture distraction osteogenesis without osteotomy.
