Dental Support and the Second Stage of Labor Among Multiparous Women

To assess if the use of the dental support device( DSD) Laboraide™ shortens the second stage of labor and decreased the rate of obstetrical interventions, and if it's use alleviate pain.

Study Overview

• Status: Unknown
• Conditions: Second Stage of Labor
• Intervention / Treatment: Device: receive Laboraide

Detailed Description

Several studies have demonstrated that a dental support device (DSD) may increase the isometric strength of different muscle groups (1-7). A preliminary pilot study of 32 women in 2009 showed that DSD may shorten the second stage of labor among nulliparous women (8) by increasing the expulsive efforts of the parturient. The study hypothesis was that DSD may decrease the length of the second stage of labor and decrease the need for obstetrical interventions such as cesarean delivery or operative vaginal delivery.

The Laboraide™ is a DSD developed specifically for use during labor. It is an inert device located between the jaws and does not interfere with speaking, breathing or any other oral activity during labor. It is a single use device, and is not transferred between women. We hypothesize that using this device can shorten the second stage of labor and decrease obstetrical intervention rate. We will also investigate it's efficiency in pain management.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: receive Laboraide; After giving consent, randomization will be carried out using sealed envelopes. After randomization women will be offered to withdraw consent. Women assigned to the study group will receive a sealed Laboraide™ package.	Device: receive Laboraide; After giving consent, randomization will be carried out using sealed envelopes. After randomization women will be offered to withdraw consent. Women assigned to the study group will receive a sealed Laboraide™ package. Labor follow up will be documented regularly including outcome. The use of the DSD will not affect the regular management of labor according to the routine standards of the delivery suite. Following delivery, patients will be asked to complete a satisfaction questionnaire.
No Intervention: do not receive Laboraide; After giving consent, randomization will be carried out using sealed envelopes. After randomization women will be offered to withdraw consent. Women assigned to the control group.
