Temporomandibular Joint Kinematics Changes in Pregnant Women: A Case-control Study

Completed

• Conditions: Pelvic Pain

• Registration Number: NCT04077775
• Lead Sponsor: Cairo University

Brief Summary

The relationship between the pelvis and stomatognathic system:

Various rationales for the relationship between the spine or pelvis and TMJ have been found. These theories include fascial, myological interrelationships, referred pain patterns and facilitating tonic neck reflexes involving inter segmental spinal pathways. A contributing mechanism could be the relationship between how TMJ occlusion, head position and body posture relate to the body's natural neurological visual/vestibular righting mechanism (Blum, 2004).

There is a Correlation between the facial axis together with the lordotic angle and the pelvic inclination, the inner gonial angle and the mandibular plane with the lordotic angle and the pelvic inclination, as well as the facial depth with the pelvic inclination showed a significant correlation (Carsten et al., 2007).

Primary Outcome Measures

Name	Time	Method
Spinal curves Measurement	3 months	spinal inclinations
Satisfaction assessed by the VAS	3 months	Degrees of menstrual pain will be assessed using a VAS, which was a method of representing subjects' pain on a 10 cm linear scale. Score of 0 meant 'no pain' and 10 meant 'worst pain'. Tomeasure specific symptoms, such as the s
pelvic tilt in degrees:	3 months	The blocks are released and the rods are placed over the crest of the ilium. The blocks are then pressed firmly toward the midline. Read the angle from the level. If the gauge reads over 21/2°, the result is listed as positive.Anterior pelvic tilting angle: PALM was used for measuring pelvic tilting angle. A mark was put on a point just inferior to ASIS; another mark was put just inferior to PSIS. The callipers of the PALM were put on these two points
body mass index	3 months	BMI in kg/m\^2
jaw movement	3 months	Maximal vertical mouth opening (MIO): From sitting position, with the use of the calliper, the distance between the incisal edges along the midline of the upper and lower central incisors without pain was measured, by placing one end of the poley gauge against the incisal edge of one of the upper central incisors, and the other end against the incisal edge of the opposing lower incisor.; The distance recorded in millimeters, the subjects was instructed to" open your mouth as wide as possible without causing pain or discomfort". The poley gauge was sterilized with antiseptic solution before and after each measure
