Study summary

Background. Bruxism is an involuntary, non-functional activity of the masticatory system, and is frequently seen in childhood. Bruxism has many aetiologies, like malocclusion, psychological factors, allergies and gastrointestinal disorders.

Aim. To investigate the relationship between Enterobius vermicularis infection and bruxism in children.

Read the detailed description

Bruxism has many aetiologies, like occlusal interferences, malocclusion, malnutrition, psychological factors, allergies and gastrointestinal disorders. Among these gastrointestinal disorders, are various intestinal parasitic infections.

Given the controversy surrounding the potential association between bruxism and intestinal parasitic infestations, both important health issues, this study sought to evaluate the relationship between E. vermicularis infection and bruxism in E. vermicularis-positive and E. vermicularis-negative 3-10-year-olds children with bruxism.

Interventions

    The parents of the patients were asked to complete a survey that included questions about the demographic data, medical history of the patient, clinical findings of E. For diagnosis of sleep bruxism, a single-use BiteStrip® device (Up2dent, Inc.), including an electromyographic electrode, small display screen and lithium cell, was used to record the increased electromyographic activity of the masticatory muscles during sleep and bruxism, other harmful oral habits, family life and habits.

What researchers measure

Primary outcomes

  1. Survey

    The parents of the patients were asked to complete a survey that included questions about the demographic data, medical history of the patient, clinical findings of E. vermicularis and bruxism, other harmful oral habits, family life and habits.

    Time frame: 24.03.2017-20.05.2018

Secondary outcomes

  1. Oral examination

    The patients who had a teeth-grinding habit were invited to, our clinic for clinical evaluation of bruxism. Patients were examined under a reflector light with inspection, palpation and mirror-sond. The extraoral examination evaluated mandibular asymmetry, joint sounds, deviation/deflection during opening/closing actions, sensitivity to palpation of masticatory muscles and pain/tenderness, sensitivity to palpation of the temporomandibular joint and masseter muscle hypertrophy10. The intraoral examination assessed the presence of wear facets on the teeth, according to a modification of the method by Johansson. The assessed teeth included primary incisors, canines and molars, permanent incisors and lower first molars. Scores were calculated as follows: 0 = no wear (none); 1 = enamel wear only (mild); 2 = enamel and dentin wear (moderate); 3 = significant loss of tooth structure (severe).

    Time frame: 24.03.2017-20.05.2018

Other outcomes

  1. BiteStrip

    For diagnosis of sleep bruxism, a single-use BiteStrip® device (Up2dent, Inc.), including an electromyographic electrode, small display screen and lithium cell, was used to record the increased electromyographic activity of the masticatory muscles during sleep.
