“…Partially dentate elders were using complete maxillary dentures and removable partial mandibular dentures, as they had mandibular class I relationship according to the Kennedy classification . The sample was calculated according previous study, in which it was estimated that 12 participants would be sufficient to detect a difference of 2 kgf in MBF between elders with and without PD . Sample size calculation was performed to achieve a power of 80% and α = 0.05, based on previous research …”

“…MBF was evaluated according to the method described in a previous study, using pressure sensors (FSR 402, 12.7‐mm diameter, 5.6‐mm thickness; Interlink Electronics Inc., Camarillo, CA, USA) placed bilaterally on the artificial first molars. Signals obtained from both sensors were recorded and analyzed using a Quantum X MX840A system (Hottinger Baldwin Messtechnik GmbH, Darmstadt, Germany) and Catman Easy software (version 3.5.1; Hottinger Baldwin Messtechnik GmbH), respectively.…”

“…The classical motor features of Parkinsonism include resting tremor, rigidity, bradykinetic movements, and postural instability . Associated orofacial manifestations include a lack of facial expression, reduced blink rate, tremors in the forehead, eyelids, lip, and tongue musculature; involuntary mandibular movements, and masticatory problems . Currently, the symptomatology of PD is considered to be heterogeneous, with clinically significant nonmotor features, such as cognitive deficits, sleep abnormalities, autonomic dysfunction, and olfactory disorders …”

“…11 Orofacial motor complications that are known to occur in patients with PD include jaw movement dysfunction and masticatory impairment. [3][4][5]12,13 Although a previous study has compared masticatory function and mandibular movements between patients with PD, during the on levodopa period, and those without PD, 4 literature has no reports about the off period impact in these outcomes. Thus, such research would be of clinical relevance since this effect may influence levodopa intake in patients with PD.…”

Aims To evaluate masticatory function and oral sensorimotor ability (OSA) in elders with Parkinson's disease (PD) during the levodopa on and off‐periods. Methods and results Participants were 11 partially and completely edentulous elders with PD. Masticatory function was evaluated by mandibular movements, maximum bite force (MBF), and masticatory performance (MP). Mandibular movements reflecting jaw range of motion (ROM) and jaw movements while chewing silicone test material (Optocal), were evaluated using a kinesiograph. MBF was assessed by strain sensors, and MP was determined using the median Optocal particle size (X50) after 40 masticatory cycles. OSA was evaluated using oral stereognosis test scores and response time. Evaluations were carried out 30 min before levodopa intake (off‐period) and within a 3‐day interval 1 h after levodopa intake (on‐period). Data were analyzed by Student's t‐test, considering a significance level of 5%. During the levodopa off‐period, elders showed decreased ROM during protrusion and lateral movements, while no difference was found in maximum opening and mandibular movements during chewing. MBF was lower and X50 was higher during the off‐period, indicating worse mastication. However, OSA did not differ between the evaluated times. Conclusion Elders with PD had impaired mastication during the levodopa off‐period, although OSA was not altered.

Background Parkinson's disease (PD) is commonly known as a disorder that affects the smooth performance of body movements. In addition to the motor impairments, patients with PD often experience pain. Both motor impairments and pain can occur throughout the body, hence including the orofacial region. However, currently, there is a lack of knowledge on the orofacial manifestations. Since orofacial pain and dysfunction can, amongst others, reduce the quality of life of patients with PD, it is important to explore the prevalence of these symptoms in the PD population. Objective To provide a broad overview of the relevant literature on orofacial pain and dysfunction in patients with PD. Furthermore, we aim to generate hypotheses for future research on this topic. Databases and data treatment A literature search (in PubMed, http://embase.com, Web of Science [Core collection], and Cochrane Library) was performed on 20 January 2022, in collaboration with a medical librarian. In total, 7180 articles were found, of which 50 were finally included in this scoping review. Results In the included studies, pain (e.g. orofacial pain (N = 2) and temporomandibular disorder pain (N = 2)), orofacial motor dysfunction (e.g. limited jaw movements (N = 10), reduced maximum muscle output (N = 3), chewing difficulties (N = 9), unspecified TMD (N = 3), sensory disturbances (N = 1)), and bruxism (N = 3) were observed more often in patients with PD than in healthy controls. Conclusion Patients with PD experience more pain in the orofacial area and more dysfunction of the masticatory system than their healthy peers. Significance This scoping review can increase health care providers' awareness of the problems that can be encountered in the orofacial area of PD patients, especially pain syndromes also occur in the orofacial region and not only in the extremities. Besides, dysfunction of the orofacial area is elaborated in this scoping review, which helps to understand that this limits PD patients' quality of life. Further, the outcomes of this scoping review can assist in encouraging collaboration between medicine and dentistry. Finally, this scoping review suggests new research areas, based on the gaps identified in the current literature on this topic. Ultimately, this will improve individualized strategies for reducing orofacial pain and/or dysfunction in PD patients.
