title: The effect of intrapartum dental support use among nulliparous during the second stage of labor - a randomized controlled study.
abstract: OBJECTIVE
  We aimed to determine the effect of a dental support device (DSD) use on the course of labor and delivery in nulliparous women.
  
  
  METHODS
  A randomized, controlled, open-label study of nulliparous (at 37 + 0/7 and 41 + 3/7 weeks of gestation) in a single tertiary university-affiliated medical center. Exclusion criteria included maternal chronic diseases, multi-fetal gestation and fetal chromosomal or structural anomalies. Outcomes were analyzed according to the actual use of the DSD, and satisfaction questionnaires following delivery.
  
  
  RESULTS
  Overall, 191 women were randomized (93in the study group and 98 in the control group). The median duration of the second stage was similar between the groups (100.0 ± 91.0 versus 98.0 ± 128.8 min, p = 0.97) and the maximal VAS score was significantly higher in the DSD group (4.0 ± 8.5 versus 3.0 ± 6.8, p = 0.04). The rate of obstetrical interventions such as operative vaginal delivery or cesarean section during the second stage was significantly higher in the control group than in the study group (28.2% versus 12.3% and 6.4% versus 1.2%, respectively, p = 0.004), mainly due to prolonged second stage of labor (24.5% versus 8.6%, p = 0.005). Of the DSD group, 50.6% rated the use of the DSD as comfortable, 32.2% rated its effect on pain relief as high, 55.6% would recommend its use to their peers and 51.9% would like to use it in their consecutive delivery.
  
  
  CONCLUSIONS
  The use of a DSD among nulliparous women appears to decrease the need for obstetrical intervention due to prolonged second stage of labor, with fair satisfaction of patients.
