Effect of contingent vibratory stimulus via an oral appliance on sleep bruxism after the splint adaptation period.

J Oral Rehabil 2021 May 13. Epub 2021 May 13.

Department of Prosthodontics, School of Dentistry, Showa University, Tokyo, Japan.

Background: Contingent vibratory feedback stimuli applied by a specially designed oral appliance (OA) have been reported to be effective in reducing sleep bruxism (SB). However, the inhibitory effects of the OA, which occur immediately after OA delivery, may have confounded this finding.

Objective: This study sought to shed light on the effects of vibratory stimuli on SB after the OA adaptation period, when its inhibitory effects are diminished. Read More

Awake Bruxism-Single-Point Self-Report versus Ecological Momentary Assessment.

J Clin Med 2021 Apr 15;10(8). Epub 2021 Apr 15.

Department of Oral Rehabilitation, The Maurice and Gabriella School of Dental Medicine, Tel Aviv University, Tel Aviv 6139001, Israel.

Assessment of awake bruxism (AB) is problematic due to the inability to use continuous recordings during daytime activities. Recently, a new semi-instrumental approach was suggested, namely, ecological momentary assessment (EMA), via the use of a smartphone application. With the application, subjects are requested to report, at least 12 times per day, the status of their masticatory muscle activity (relaxed muscles, muscle bracing without tooth contact, teeth contact, teeth clenching, or teeth grinding).

Department of Propaedeutics of Dental Diseases, A.I. Yevdokimov Moscow State University of Medicine and Dentistry, 127473 Moscow, Russia.

A 3D finite element model of the mandible dentition was developed, including 14 teeth, a periodontal ligament (PDL), and a splint made of polymethylmethacrylate (PMMA). The study considered three design options: 1-the case of splint absence; 2-the case of the splint presence installed after manufacture; and 3-the case of splint presence installed after correction (grinding) performed to ensure a uniform distribution of occlusal force between the teeth. For cases of absence and presence of splint, three measurements of the functional load were performed using the T-Scan III software and hardware complex (TekScan, Boston, MA, USA). Read More

Ji-Young Song

J Korean Assoc Oral Maxillofac Surg 2021 Apr;47(2):149-150

Department of Dentistry, School of Medicine, Jeju National University, Jeju, Korea.

Bruxism is defined as a parafunctional activity during sleep or while awake that includes locking and grinding of teeth and clenching. It generates excessive occlusal force that may lead to implant failure. Therefore, diagnosis of bruxism and providing specific protocols such as occlusal splint and/or injection of botulinum toxin before implant installation are important to prevent increases the risk of implant failure in bruxism patients.

Minerva Dent Oral Sci 2021 Apr 28. Epub 2021 Apr 28.

School of Dentistry, Department of Surgery, Dentistry, Paediatrics and Gynaecology (DIPSCOMI), University of Verona, Verona, Italy.

Background: There are increasing evidences of the influence of the oropharyngeal stimulations on the autonomic nervous system and an easy approach to evaluate the balance between parasympathetic and sympathetic system is the measurement of the pupil diameter. The aim of this analytic observational study is to define the effects of clenching and swallowing on pupil diameter, and how an oral appliance can affect the outcome of these tasks, to establish their influence on the sympathetic-parasympathetic balance.

Methods: We measured the pupil diameter in 30 healthy subjects during clenching and swallowing, both with and without oral appliance. Read More

Bruxism in Acute Neurologic Illness.

Curr Pain Headache Rep 2021 Apr 10;25(6):41. Epub 2021 Apr 10.

Division of Neurocritical Care, Weill Cornell Medicine, New York Presbyterian, 525 East 68th St, RM F610, New York, NY, 10065, USA.

Purpose Of Review: While traditionally encountered in ambulatory settings, bruxism occurs in patients with a variety of acute neurologic illnesses including encephalitis, intracerebral hemorrhage, traumatic brain injury, hypoxic-ischemic encephalopathy, and acute ischemic stroke. Untreated bruxism in acute neurologic illness can lead to tooth loss, difficulty in mouth care resulting in recurrent aspiration pneumonia, endotracheal tube dislodgement, and even tongue laceration or amputation. Inpatient clinicians should be aware of the etiologies and management strategies for bruxism secondary to acute neurologic illness. Read More
