| Methods |
Radomised controlled cross‐over study; allocation concealment unclear; blinded data collection; the order of the treatment was randomised for each participant; 1 month and a half washout period between treatments. |
| Participants |
11 participants who grinded their teeth were diagnosed via anamnese and/or a questionnaire, clinical examination, and tooth grinding reported by partner. Among all patients, 5 presented temporomandibular disorders (TMD) at the initial evaluation. |
| Interventions |
Group A: Occlusal splint (n = 11). They wore their splint 24 hours a day except for eating, for a 45‐day period.
Group B: TENS (n = 11). Each TENS session lasted 45‐60 minutes and each patient underwent 15 sessions (1 every 2 days). |
| Outcomes |
Clicks recorded in both temporomandibular joints (TMJ) during oral opening and closing; clicks recorded in both TMJ during either oral opening or closing; pain in some TMJ; headache. |
| Notes |
The following completed data were acquired by personal communication: 1) Allocation sequence was generated by random number tables. 2) 13 clenchers clenched their teeth during the day. 3)The criteria used to identify the bruxers were dental abrade and muscle hypertrofia by clinical exam and teeth griding reported by partner. 4) Allocation concealment was performed (the answer was unclear).
Setting: Participants were recruited from the Dental School of the University of Oviedo (Spain) and from dental private clinics. |
