Objective: To determine the prevalence of hydatidosis in dromedaries.Methods:2011. The relationship between host age and the mean number of hydatid cysts, and prevalence and fertility rates was analyzed using chi-square test.Results:438 dromedaries were examined in five regions of Iran from 20 March, 2010 to 19 March, Echinococcus granulosus. Number of cysts was 700 with 72.5% lung cyst. The highest rate of infection was that 54 (40%) of camels was found in the Khorasan Razavi region (in the north-east part of Iran) while the lowest 6 (4.4%) of camels was found in Semnan province. Infection was higher in >15 years age group. The most commonly infected organs were lungs (72.5%) followed by liver (12.6%). Both liver and lungs together constituted 14.8% of infection. A comparison found that hydatid cysts of liver had a higher fertility rate (32.57%) than that of lung (19%); while most of cysts of lung were calcified (24.42%). The mean number of protoscoleces per mL in the lung fertile cysts was higher than that of liver cysts. Fertile or sterile might be due to the different species or genotypes. The mean number of cysts in infected liver and lungs was 1-5 cysts. The intensity of infection increased with age.Conclusions:The results of current study can make a background data for implementing hydatid One hundred and thirty five out of 438 (30.82%) camels harboured hydatid cysts of control programs and warrant the importance of camel in public health.

OBJECTIVE: The aim of this study was to evaluate discoloration of teeth undergoing regenerative endodontic procedures (REPs) using blood clot or platelet-rich fibrin (PRF) as the scaffolds and different calcium silicate-based materials as the intracanal coronal barriers in an ex vivo model. MATERIALS AND METHODS: Forty-eight bovine incisors were prepared and disinfected using 1 mg/mL double antibiotic paste (DAP). The specimens were then randomly divided into 2 groups (n = 24) according to the scaffolds (blood or PRF). After placement of scaffolds each group was divided into 2 subgroups (n = 12) according to the intracanal coronal barriers (ProRoot MTA or Biodentine). The pulp chamber walls were sealed with dentin bonding agent before placement of DAP and before placement of scaffolds. The color changes (∆E) were measured at different steps. The data were analyzed using 2-way analysis of variance. RESULTS: Coronal discoloration induced by DAP was not clinically perceptible (ΔE ≤ 3.3). Regarding the type of the scaffold, coronal discoloration was significantly higher in blood groups compared with PRF groups at the end of REP and after 1 month (p < 0.05). However, no significant difference was found between PRF and blood clot after 6 months (p > 0.05). Considering the type of intracanal coronal barrier, no significant difference existed between ProRoot MTA and Biodentine (p > 0.05). CONCLUSIONS: With sealing the dentinal tubules of pulp chamber with a dentin bonding agent and application of DAP as an intracanal medicament, coronal color change of the teeth following the use of PRF and blood sealed with either ProRoot MTA or Biodentine was not different at 6-month follow-up.

OBJECTIVETo determine the prevalence of hydatidosis in dromedaries.

METHODS438 dromedaries were examined in five regions of Iran from 20 March, 2010 to 19 March, 2011. The relationship between host age and the mean number of hydatid cysts, and prevalence and fertility rates was analyzed using chi-square test.

RESULTSOne hundred and thirty five out of 438 (30.82%) camels harboured hydatid cysts of Echinococcus granulosus. Number of cysts was 700 with 72.5% lung cyst. The highest rate of infection was that 54 (40%) of camels was found in the Khorasan Razavi region (in the north-east part of Iran) while the lowest 6 (4.4%) of camels was found in Semnan province. Infection was higher in >15 years age group. The most commonly infected organs were lungs (72.5%) followed by liver (12.6%). Both liver and lungs together constituted 14.8% of infection. A comparison found that hydatid cysts of liver had a higher fertility rate (32.57%) than that of lung (19%); while most of cysts of lung were calcified (24.42%). The mean number of protoscoleces per mL in the lung fertile cysts was higher than that of liver cysts. Fertile or sterile might be due to the different species or genotypes. The mean number of cysts in infected liver and lungs was 1-5 cysts. The intensity of infection increased with age.

CONCLUSIONSThe results of current study can make a background data for implementing hydatid control programs and warrant the importance of camel in public health.
