Effects of Two Different Physical Therapy Protocols After an Endodontic Intervention

Universidad de Zaragoza29 enrolled

Overview

The purpose of this study was to evaluate the clinical results produced by a manual therapy treatment combined with dry needling (MT+DN) and a manual therapy treatment (TM) versus a control (C), to normalize the altered cervico-mandibular variables after a session of root canal therapy.

Interventions

Manual Therapy + Dry NeedlingOTHER

Dry Needling: This is a minimally invasive procedure where a fine needle or acupuncture needle is inserted into the skin and muscle in order to stimulate myofascial trigger points (MTrP) provoking one to six local twitch responses (LTR). Manual Therapy Protocol: Intraoral manual techniques were applied to the musculature of both sides, both masseter and medial pterygoid, consisting of both massage and stretching. Furthermore, a grade I-II in the slack-zone traction was applied in the temporomandibular joint (TMJ).

Outcomes

Primary Outcomes

Mean change from baseline in Maximum Active Mouth Opening at 1 week

An electronic caliper (HIBOK DC-516) will be used to measure maximum active mouth opening in supine position. Patients will be instructed to open the mouth as wide as possible without feeling any pain and the distance between upper-lower central incisors (intercisal distance) will be measured in mm.

Time frame: Baseline and 1 week

Secondary Outcomes

Mean change from baseline in Pain intensity at 1 week

Pain intensity will be measured using a visual analogue scale (VAS) from 0 to 10 (where 0 is no pain and 10 is the worst pain imaginable).

Time frame: Baseline and 1 week

Mean change from baseline in Pressure Pain Threshold (PPT) at 1 week

The examiners assess the PPT using a handheld algometer (Wagner, Model FPK). The PPT will be measured bilaterally in the following points of the craniofacial and cervical region: masseter, temporalis, upper trapezius, splenius capitis and suboccipital muscles, and temporomandibular joint. The thenar eminence will be also measured in order to evaluate central sensitization (general pain hypersensitivity) within an intervention-free anatomical location.

Time frame: Baseline and 1 week

Mean change from baseline in Myofascial Trigger Points (MTrPs) at 1 week

The following muscles of the temporomandibular and cervical regions will be examined: masseter, temporalis, sternocleidomastoid, upper trapezius, splenius capitis and suboccipital muscles.

Time frame: Baseline and 1 week

Mean change from baseline in Cervical Spine Range of Movement (ROM) at 1 week

The examiners assess the cervical ROM using the Clinometer App (version 2.4) for smartphone and a standard goniometer. Cervical flexion, extension, right/left sidebending, right/left rotation, as well as upper cervical spine flexion and extension will be evaluated.
