“…Masticatory dysfunction refers to a debilitating condition in which normal masticatory function is compromised by functional factors (e.g., poor masticatory performance) or structural factors (e.g., tooth loss). Studies have reported that the prevalence of masticatory dysfunction in the elderly is 20.3-56.9% (4)(5)(6). Masticatory dysfunction can significantly reduce the nutrient intake levels of older people, except for carbohydrate intake (7).…”

Background: Decreased masticatory function contributes to malnutrition in the elderly. The purpose of our study was to explore whether the masseter muscle is involved in masticatory function in older adults and to help determine if the masticatory function of the elderly can be improved by exercising the masseter muscle.Methods: Random sampling was adopted in our research, and a total of 413 older adults from 9 nursing homes in China were recruited from March 10 to June 12, 2022. The thickness and echo intensity of their masseter muscles were assessed using ultrasound. Masticatory function was measured using a color-changing chewing gum, and the change of α* before and after chewing (Δα*) was defined as masticatory function.If Δα* <14.2 in males or <10.8 in females was masticatory dysfunction. Their number of molar occlusal supports (MOSN), comorbidity, oral diadochokinesis (ODK), maximum tongue pressure (MTP), and calf circumference (CC) were evaluated. Multiple linear regression analysis was performed to identify the factors independently associated with the masticatory function.Results: Of the 413 older adults, 179 (43.3%) had masticatory dysfunction. The average thickness of the masseter muscle between contraction and relaxation was 1.3 mm (range, 0.7-2.0 mm). The thickness of the masseter muscle and ODK decreased with age, while the echo intensity of the masseter muscle increased.The results of the multiple linear regression analysis showed that dynamic change in the thickness of the masseter muscle between contraction and relaxation (β=0.085; P=0.049), MTP (β=0.147; P=0.001) and MOSN (β=0.349; P<0.001), brushing teeth ≥2 times/day (β=−0.187; P<0.001), and CC (β=0.135; P=0.002) were independent factors affecting masticatory function.Conclusions: We found that masticatory dysfunction was prevalent among older adults in nursing homes in Southwest China, and the dynamic change in the thickness of the masseter muscle between contraction and relaxation was positively correlated with masticatory function. This result suggests that we can improve the masticatory function of the elderly by increasing the thickness of the masseter muscle between contraction and relaxation (e.g., by exercising the masseter).

“…The function and integrity of the masticatory system have an important impact on a person's quality of life (Fujimoto et al, 2020). Poor health of the masticatory system may be caused by many interrelated factors, including tooth decay, tooth loss, malocclusion, temporomandibular joint dysfunction, and mandibular fractures.…”

In dental research, bite force has become an important curative effect evaluation index for tooth restoration, periodontal treatment, and orthodontic treatment. Bite force is an important parameter to evaluate the efficacy of the masticatory system. Physicians obtain the therapeutic basis for occlusal adjustment by measuring the bite force and the dynamic changes in occlusal contact at different stages of treatment and objectively evaluate the therapeutic effect. At present, many devices are used to record the bite force. Most of these devices use force transducers to detect bite force, such as strain gauge transducers, piezoresistive transducers, piezoelectric transducers, optical fiber transducers, and pressure-sensitive films. This article summarizes the various equipment used to record bite force, related materials and the characteristics of this equipment. It provides a reference for physicians to make choices during the clinical process and at the same time provides a basis for the development of new occlusal force measurement materials.

“…Hence, dental infections and inflammation may be aggravated among older people, resulting in worse oral health and obviously promoting a negative self-assessment of their oral health and OHRQoL. 33 A compromised oral health statuses may also contribute to the frailty process given the associated consequences, such as oral hygiene difficulties, chewing problems and malnourishment, 34,35 and sarcopenia. 36,37 The intercorrelation between these conditions suggests the existence of a complex net evolving frailty, oral health, and OHRQoL in older adults.…”

Frailty and oral health-related quality of life in community-dwelling older adults: a cross-sectional study

et al. 2021

Poor oral health has been associated with frailty among older adults. However, limited evidence has been available on whether frailty can affect oral health-related quality of life (OHRQoL) in older adults. This study aimed to investigate the relationship between frailty and OHRQoL among community-dwelling older adults. A household-based cross-sectional study involving community-dwelling older adults aged 65 years and older was conducted in the city of Bauru, Brazil. Data on frailty status, sociodemographic characteristics, self-perceived dental care needs, and OHRQoL (OHIP-14) were collected through individual interviews. The use of and the need for total dental prostheses were assessed through clinical examinations. Logistic regression was used to determine whether frailty status and covariates were associated with OHRQoL prevalence measures (OHIP-14 total score ≥ 1 and OHIP-14 fairly/very often ≥ 1). The sample comprised 334 participants, among whom 58.7% and 41.3% were between 65-74 and 75-102 years old, respectively. The prevalence of moderate to severe frailty was 12.3%. Moderate to severe frailty (OR = 4.49; 95%CI 1.29-15.66), the need for lower dental prosthesis (OR = 2.20; 95%CI 1.27-3.81), and self-perceived dental care need (OR = 3.90; 95%CI 2.14-7.14) were associated with OHIP-14 total score ≥1. Moderate to severe frailty (OR = 2.95; 95%CI 1.33-6.55), being female (OR = 2.24; 95%CI 1.34-3.75), and self-perceived dental care need (OR = 4.80; 95%CI 2.86-8.03) were associated with OHIP-14 fairly/very often ≥1. Overall, our results showed that moderate to severe frailty was significantly associated with poor OHRQoL in community-dwelling older adults.
