Objective: to evaluate the effects of physiotherapy on the anteroposterior airway size in a group of bruxist children

Question: Is a physiotherapeutic technique aiming at changing the head posture, effective to increase the anteroposterior dimensions of the upper airway in bruxist children?

Hypothesis: The bruxist children treated with physiotherapy will present higher airway dimensions

Design: randomized clinical trial with allocation and blinding of the examiners.

Participants: 3 to 6 year old children with complete primary dentition, dental and skeletal class I occlusion. The participants were classified as bruxist according to the minimal criteria of the ICSD for bruxism. The children were randomized in an experimental (n=13) and a control (n=13) group.

Intervention: A physiotherapeutic intervention using the Awareness through movement technique was applied to the children of the experimental group once a week, until 10 sessions were completed.

Outcome measures: anteroposterior measurements of the nasopharynx, oropharynx and hypopharynx taken in a lateral cephalogram with standardized techniques.

Primary Outcome Measures:
  • ad1 [ Time Frame: After 10 sessions of physiotherapy ]
    ad1: Distance between the posterior nasal spine (PNS) and basion (Ba) along the line which intersects the anterior and posterior pharyngeal wall.

  • ad2 [ Time Frame: After the 10 sessions of physiotherapy ]
    ad2: Distance between the anterior and posterior pharyngeal wall traced perpendicular to the plane sella (S) Ba plane and passing through PNS.

  • Angle ad1-ad2 [ Time Frame: After 10 sessions of physiotherapy ]
    Angle ad1-ad2: angle formed by ad1 and ad2.

  • OAW1 [ Time Frame: After 10 sessions of physiotherapy ]
    OAW1: the distance between the points where the functional occlusal plane intersects the anterior and posterior pharyngeal walls.

  • OAW2 [ Time Frame: After 10 sessions of physiotherapy ]
    OAW2: the distance between points where a line passing through hyoid (hy) and C2 i intersects the anterior and posterior pharyngeal walls.

  • OAW3 [ Time Frame: After 10 sessions of physiotherapy ]
    OAW3: the distance between the points where a line passing through hy and C4 i intersects the anterior and posterior pharyngeal walls.

  • Angle OAW2-OAW3 [ Time Frame: After 10 sessions of physiotherapy ]
    Angle OAW2-OAW3: angle formed by OAW2 and OAW3.

  • SPPS [ Time Frame: After 10 sessions of physiotherapy ]
    SPPS: anteroposterior dimension of the pharynx measured between the posterior pharyngeal wall and the dorsum of the soft palate on a line parallel to the Frankfort horizontal (FH) plane that runs through the middle of a line from PNS to the distal extreme of the soft palate (P).

  • IPS [ Time Frame: after 10 sessions of physiotherapy ]
    IPS: anteroposterior dimension of the pharynx measured between the posterior pharyngeal wall and the dorsum of the tongue on a line parallel to the FH plane that runs through C2i

Arms Assigned Interventions
Experimental: Physiotherapy
group of bruxist children that received physiotherapy to change the head posture
Other: Physiotherapy

The physiotherapeutic intervention was based on the Awareness through Movement technique. Ten sessions were planed. Each session lasted three hours.

The children of the experimental group and their parents were guided by two physiotherapist and the sessions took place in a room rounded by mirrors.

Each session developed as follows: presentation to the parents of the somatic awareness technique for each day; movements, games, motor tales and exercises performed by the children; in each session, a guide book with cartoons was given to the children and their parents to reinforce the exercises at home to keep a long-term result.

All the children assisted together to all the sessions and the instructions and instruments given to the children and their parents were the same for all of them.
