Functional movementscreen-) FMS (and Y balance- test are functional assessment tools with some specific relevance. However, information regarding a potential relationship between these assessments and Hop test is still insufficient. Additionally, the FMS and Y balance are used to predict the risk of sport injuries occurrence. Currently, no research is available on the differences in FMS, Y balance, and Hop test between groups with high and low risks of sport injuries.

One hundred and thirty-one premier league young adolescents (man/woman) volleyball players from Zanjan Province (age=15.78±1.83 years old; height= 176.30±7.07 cm; weight= 67.56±6.18 kg; BMI=21.74±1.63 kg/m2) participated in this cross sectional study. The pre-participation screening consisted of FMS, Y balance, DEVIS, and Hopping test has been recorded during the pre-season time. All participants followed the routine training in season. Volleyball players were divided based on the FMS score considering scores ˃14 as low risk criteria and ≤14 as high risk criteria of sustaining musculoskeletal injury. The correlations of composite and individual item scores of these assessments were analyzed, and the differences between groups with high and low risks of sports injury were compared.

independent t test showed the Y balance, DEVIS, and Hopping tests scores were all significantly higher in athletes who got FMS scores ˃14 comparing to those who got FMS scores ≤14.

the result showed functional movement test scores are different among volleyball players with/without high risk of sustaining musculoskeletal injuries. Athletes who get FMS scores ≤14 (whom are likely to sustain injuries) are supposed to have lower scores on other functional movement tests as well. It is therefore suggested that functional movements screening tests might be of use for recognizing those athletes with higher risks of sustaining musculoskeletal injury.

The antibacterial activity of three endodontic sealers, a Ca(OH)2 based sealer (apexit) a Zoe based sealer (Drofill) and a resin based sealer (AH26) was assessed on the growth of an anaerobic bacteria (peprostreptococcus spp.) using the Agar diffusion test (ADT). Thirty brain heart diffusion agar plates were incubated with peptostreptococcus anaerobics. Each plate was divided into two separate areas. In one area, 0.1ml droplet of a given fresh sealer and in the other area a dry material of the same sealer were placed, such that each plate had two areas with the same sealer in two forms of fresh and dry (setform). There were ten plates for each of the three sealers. The plates were placed into anaerobic jars and incubated at 37°C. After varying periods, zone of inhibition of bacterial growth were observed, measured and compared by t and Paired T-test. There was no statistically significant differences between the activity of AH26 and drofill in the fresh form(P>0.05). However there were significant differences between (the two sealers in set form) (P<0.05) Drofill was more antibacterials in the set form than AH26. All sealers were more active when fresh than ages. It is likely that the eugenol in the Dorifill and the formaldehyde in the AH26 are responsible for their greater antimicrobial activity.
