NCT05420129

Brief Summary

This study evaluates the effect of the use of mandibular advancement devices (MAD) on dental occlusion and masticatory function during the first two years of obstructive sleep apnea (OSA) treatment. 52 participants diagnosed with obstructive sleep apnea will be studied, 26 will be treated with MAD and 26 participants will be treated with continuous positive airway pressure (CPAP) as a control group. Participants will perform masticatory tests to assess masticatory performance in comminute and mixing capacity. Masticatory satisfaction perceived by the participants will be evaluated by questionnaires. Occlusal contact area and other occlusal characteristics will be assessed using occlusal silicone and T-Scan registrations and 3D digital models obtained with intraoral scan. Data collection will be performed before treatment with MAD or CPAP, and at 3, 6, 12, and 24 months from the start of treatment.

Outcome Measures

Primary Outcomes (2)

  • Change in masticatory perfomance at 6 months

    The masticatory performance will be evaluated by assessing the degree of comminution of the silicon test food (Median particle size). The particles from five trials (10 g) will be dried and passed through a series of eight sieves (0.25, 0.425, 0.85, 2, 2.8, 3.15, 4, and 5.6 mm) while being shaken for 6 min. Once the cumulative weight distribution of the sieve contents will be determined, the median particle size (MPS) will be calculated for each subject using the Rosin-Rammler equation \[Qw (X) = 1 - 2E-(X/ X50)b\], where Qw (X) is the fraction of particles by weight with a diameter smaller than X; X50 (or MPS) is the size of a theoretical sieve through which 50% of the weight would pass; and b describes the breadth of the particle size distribution. Therefore, the lower the MPS, the better the masticatory performance. Participants will perform masticatory tests before and 6 months after treatment.

  • Change in masticatory perfomance at 24 months

    The masticatory performance will be evaluated by assessing the degree of comminution of the silicon test food (Median particle size). The particles from five trials (10 g) will be dried and passed through a series of eight sieves (0.25, 0.425, 0.85, 2, 2.8, 3.15, 4, and 5.6 mm) while being shaken for 6 min. Once the cumulative weight distribution of the sieve contents will be determined, the median particle size (MPS) will be calculated for each subject using the Rosin-Rammler equation \[Qw (X) = 1 - 2E-(X/ X50)b\], where Qw (X) is the fraction of particles by weight with a diameter smaller than X; X50 (or MPS) is the size of a theoretical sieve through which 50% of the weight would pass; and b describes the breadth of the particle size distribution. Therefore, the lower the MPS, the better the masticatory performance. Participants will perform masticatory tests before and 24 months after treatment.
