Objective To investigate the effect of different investing materials on the complete denture flasking deformation.Methods The denture wax casts were invested by plaster,dental stone,and dental stone together with silicone,respectively.8 trial dentures were randomly chosen from above each group,and 4 reference points were selected in the cast.The conventional water bath polymerization system was used for the process.The distance between reference points were measured before and after thermally processing the Acrylic base.F test and Kruskal-Wallis H test were applied for statistical analysis.Results The distance between A and B (F =3.768,P =0.040) and the mean of total distance among O,A,B and C(F =4.830,P =0.019) had statistically significant differences among the three groups.The deformation variance of Group 1 (a conventional plaster) between 175μm and 267μm was maximum.The deformation values of Group2 (a dental stone) was appropriate with Group3 (a dental stone + a silicone).Smoothness (x2 =17.575,P ＜ 0.01) was statistically different among the three groups.Conclusion The flaskingprocess with the plaster had the maximum movement.The process with dental stone showed the minimal toothmovement,the process with the dental stone along with with thesilicone caused a similar movement as from the single dental stone but resulted in a smoother denture surface.

Objective To study the reproductive outcome of infertile women suffered from hydrosalpinx treated by laparoscopic salpingostomy or salpingectomy.Methods There were 77 infertile women diagnosed hydrosalpinx by HSG or B ultrasonography and excepted for other infertile factors. Unilateral or bilateral salpingostomy or salpingectomy was performed after hydrosalpinx conifrmed by laparoscopy. Seventy seven patients were followed up for 1 ~ 4 years postoperatively.Results Among 77 cases 39 cases (50.65%) got pregnancy. Thirteen cases (16.88%) conceived spontaneously and 26 cases (33.77%) conceived by IVF-ETin. Thirty ifve cases delivered health babies and 3 cases of pregnancy, 1 cases of early abortion.Conclusion Both laparoscopic surgeries were effective treatment of hydrosalpinx results in infertility. After operation the pregnant rate of those conceived by IVF-ET is higher than spontaneously.
