BACKGROUND:The surface of dental impression is inevitable to carry various bacteria caused by direct contact with the patient saliva, mucosa and blood during preparation;therefore, disinfection of the dental impression is necessary. OBJECTIVE:To evaluate the disinfection efficiency of glutaraldehyde, chlorine dioxide and electrolyzed oxiding water on dental impressions and to investigate the dimensional stability of impressions after disinfection, thus providing basis for establishing a standard and reasonable disinfection method. METHODS:Alginate impression materials were contaminated in vitro, and then immersed in glutaraldehyde, chlorine dioxide and electrolyzed-oxiding water for 5, 10 and 15 minutes, respectively. The colonies were counted after germiculture to compare the disinfection efficiency of three disinfectants. The impressions were poured in die stone after immersion, the dental models were structured-light scanned and three-dimensional digital dental models were reconstructed. Al the data were global y registered, and linear dimensions were measured on the digital models to deduce the influence of disinfection on surface accuracy and dimensional stability of the impressions. RESULTS AND CONCLUSION:The disinfecting rate reached 100%through immersion in 2%alkaline glutaraldehyde for 5 minutes, and the disinfection of kil ing the hepatitis B virus was effective after 10-minute immersion. The disinfecting rate of 600 ppm chlorine dioxide for 15 minutes kil ing experimental bacteria reached 99%and effective for kil ing the hepatitis B virus. While the disinfecting rate of kil ing experimental bacteria was less than 99%through immersion in electrolyzed oxiding water for 15 minutes, and was not effective for hepatitis B virus. The three-dimensional digital dental models did not differ significantly. These results suggest that immersion in 2%alkaline glutaraldehyde for 10 minutes or 600 ppm chlorine dioxide for 15 minutes can effectively disinfect alginate impressions and make no significant effect on the dimensional stability.

Objective Knowledge?based radiotherapy ( KBRT ) can reduce the plan quality variability induced by different experiences between physicians and improve the quality of treatment plans. Methods The Varian Rapid Plan system was used to train a dose?volume histogram ( DVH) prediction model. The obtained model was preliminarily applied to semi?automatic design of the preoperative treatment plans for rectal cancer. Eighty high?quality volumetric modulated arc therapy plans were imported into the model training set of the Rapid Plan system. The structures of the plans were matched to the corresponding labels and codes as listed in the library. The training started after the verification of prescription. The residual plots,regression curves,geometric plots for organ at risk ( OAR) ,in?field DVH plots,and model training logs were examined. After removal of the mismatch, the original plans were assessed to rule out outliers and influential data points. More similar plans may be added for another round of training. Ten KBRT plans were designed using the final model and compared with the clinical plans. Results For the two major OARs,the femoral head and bladder,the average goodness of fit of the principal component were 0?999 415/1.0 and 0?999 963/1.0 for the DVH model,and 0?999 651/1.0 and 0?999 945/1.0 for geometry?based expected dose model,respectively. In all the plans, 11 had Cook ’ s distance values exceeding the tolerance and 4 had studentized residual values exceeding the tolerance. The outliers were all kept in the training set to generalize the scope of the model. The 10 KBRT plans had significantly improved homogeneity indices for PGTV and PTV than the original plans (P=0?00,0?04).The 10 KBRT plans also had significantly reduced D50% to the femoral head and bladder as well as significantly reduced mean doses to the bladder than the original plans (P=0?042,0?000,0?005). Conclusions In this study,the Rapid Plan system is used to train a KBRT model for design of preoperative radiotherapy plans for rectal cancer. The results of preliminary application meet the clinical requirements.

Objective To compare the dosimetric difference of RapidArc and fixed gantry angle dynamic IMRT (dIMRT) for loco-regionally advanced nasopharyngeal carcinoma.Methods Ten previously treated patients with loco-regionally advanced nasopharyngeal carcinoma were replanned with RapidArc and dIMRT, respectively.The prescription dose was GTV 70 Gy/33 f and PTV 60 Gy/33 f.All plans met the requirement:95% of PTV was covered by 60 Gy.Dose-volume histogram data, isodose distribution, monitor units,and treatment time were compared.Results Dose distribution has no significant difference between the two techniques.RapidArc reduced the dose of the brainstem, mandible, and other normal tissues compared with dIMRT.Mean monitor units were 589.5 and 1381.0 for RapidArc and dIMRT (reduced by 57% relatively).Mean treatment time was 2.33 min and 7.82 min for RapidArc and dIMRT (reduced by 70% relatively).Conclusions Compared with dIMRT, RapidArc achieves equal target coverage and OAR sparing while using fewer monitor units and less time during radiotherapy for patient with loco-regionally advanced nasopharyngeal carcinoma.

Objective To compare the dosimetric differences of target and organs at risk (OAR) induced by the tangential and non-coplanar multi-fields used in the dynamic intensity modulated radiotherapy (IMRT) plans for breast cancer patients after breast-conserving surgery.Methods Forty patients with early-stage left breast cancer after breast-conserving surgery were included.Based on the CT anatomy of the same patient,dynamic IMRT treatment plans using two tangential fields,3,4 and 5 non-coplanar fields were designed respectively utilizing the same optimization objects.The plans were compared by means of target dose distribution,the doses and irradiated volumes of heat,left lung,right breast,and total monitor units (MUs).Results The conformal index (CI) and homogeneity index (HI) of planning target volume (PTV) in the plans using 4 and 5 fields were better than that using 2 fields (P ＜ 0.05).Maximum doses (Dmax) in PTV were significantly lower in the plans of 4 and 5 fields than of 2 fields (P ＜0.05).Yet the plans of 4 and 5 fields generated significant higher minimum doses (Dmin) in PTV than that of 2 fields (P ＜ 0.05).No significant difference was observed between plans of 2 or 3 fields.Across the four plans,the differences of right breast V5 (relative volume acquired at least 5 Gy of dose),heart V30,heart mean dose (D),left lung V20,V5 and D were not significant.Yet the disparities of total MUs were statistically significant (F =25.63,P ＜ 0.05).The least MUs were used by the 2 fields and the most MUs were observed in the 5-field plans.Conclusions Comparing with IMRT plans of 2 fields,using 4 or 5 non-coplanar fields can improve the target dose distribution without increasing OAR doses.As a tradeoff,more MUs are needed for multi-fields plans.
