“…PDL displacement induces short latency depolarisations in the mesencephalic nucleus of the trigeminal nerve and motor neurons of the jaw elevator muscles during chewing. During clenching, the periodontal input inhibits the larger motor units and hence limits further increase in bite force …”

Aim This study aims to compare surface electromyographic activities (EMG) of four muscles, that is anterior temporalis (AT), masseter (MST), sternocleidomastoid (SCM) and anterior belly of digastric (ABD), between chronic periodontitis patients and periodontally healthy individuals as well as to correlate these EMG findings with periodontal parameters. Methods Thirty chronic periodontitis patients were recruited in Group I and 30 periodontally healthy individuals in Group II. Clenching and resting EMG for 4 muscles (AT, MST, SCM and ABD) were recorded for each participant. These EMG values were compared between the groups and correlated with periodontal parameters (plaque index, modified sulcular bleeding index, probing depth and clinical attachment loss). Results Resting EMG (rEMG) showed no significant difference between the groups for any muscle. Clenching EMG (cEMG) values were significantly lower in Group I than Group II for AT and MST (P = .001), but not so for SCM and ABD. Within Group I, AT and MST showed a significant negative correlation of cEMG with probing depth and clinical attachment loss (P < .05). Conclusion Electrical muscle activities of AT and MST are lower in chronic periodontitis than periodontally healthy individuals.

“…The sensory information from periodontal tissues contributes not only to rhythmical masticatory movement (1–5) but also to escape from movement by accidental mechanical overloading (6–10). Teeth are occasionally subjected to heavy mechanical loading, such as teeth clenching or grinding (11).…”

“…Some studies show a relationship between the sensory innervation and the function of the masticatory system through so-called nociceptive and proprioceptive reflexes (Okeson, 2003;Lavigne et al, 1987;Willis & DiCosimo, 1979). This implies an important feedback between the sensitive innervation and the muscular function.…”

Mandible Measurements and Dental Midline Deviation after Alveolar Nerve Transection in Growing Rabbits

et al. 2011

SUMMARY:The relationship between sensitive innervation and normal mandibular bone development has been described in the literature. Therefore, neural damage is a potential cause of osseous deformities, particularly in growing subjects. The aim of this project is to present the mandible measurements obtained after the transection of the inferior alveolar nerve of growing rabbits. A specific surgical protocol was designed to carry out the unilateral nerve transection by avoiding musculoskeletal injuries. Twenty New Zealand White rabbits one week post-weaning were used, 12 as an experimental group and 8 as a control group (Sham operated). The animals were sacrificed 90 days postoperatory, and the mandibles carefully dissected. Dental midline deviation data were obtained under anesthesia, previous to sacrifice. All measurements were obtained with a micron digital caliper. For this study, only anterior-posterior measurements were obtained from five points specifically determined on the rabbit mandible. Each measurement was made three times by the same examiner and the average value was considered. Regarding the anterior-posterior measurements, the molar and incisive regions of the denervated hemimandible were significantly shorter than the corresponding regions in the non-denervated side. The control group did not show these differences. A dental midline deviation was observed, but not always directed on the operated side. However, the deviation values were greater when oriented to the denervated side. These changes did not cause evident deformity or dysfunction in the masticatory system of the animals. They were fed normally and their weight was considered within normal parameters while growing. Despite the biological relationship between sensory inervation and bone morphology, the effect of sensory denervation in early stages of bone growth appears to generate only small alterations on the mandible morphology. However, these alterations do not lead to functional problems in the masticatory system.
