“…Subsequently, a possible masticatory disability that could lead to the avoidance of foods can be discussed. Simple dietary advice as given by dentists appeared to improve nutrient intake of edentulous elderly people who had received new CDPs; without such advice, an improvement could not be assessed [36,37]. In selected cases, discussion with informal caregivers and/or referral to medical professionals (e.g., the family doctor or a dietician) is worth considering.…”

Objectives To investigate associations between food avoidance and dental status, age, gender, and socio-economic status (SES). Materials and methods The Chinese sample comprised 1463 dentulous (≥ 1 tooth in each jaw) and 124 edentulous (in one or both jaws) participants aged ≥ 40 yrs. The Vietnamese sample comprised 2820 dentulous and 253 edentulous participants aged ≥ 20 yrs. Food avoidance due to chewing difficulties was scored for regionally common 4 soft and 4 hard foods. Dental status was classified according to the multi-level hierarchical dental functional classification system (HDFC) based on the number and location of teeth and posterior occlusal pairs. Associations were analyzed using multivariate logistic regression analyses. Results For dentulous participants, the chance of avoiding foods was significantly larger with < 10 teeth in each jaw (OR = 2.26 (Chinese sample), respectively 1.74 (Vietnamese sample)), incomplete anterior region (OR = 1.78, respectively 1.84), Bimpairedp remolar region (OR = 2.22, respectively 1.71), or Bimpaired^molar region (OR = 2.46, respectively 1.84). Edentulous participants had twice the chance of avoiding foods (OR = 2.01 respectively 2.20). Avoiding foods was significantly associated with higher age. Participants of low SES (Chinese sample, OR = 1.93) and females (Vietnamese sample, OR = 1.27) had a larger chance of avoiding foods. Conclusions Avoiding foods was significantly associated with reduced dentitions, edentulousness, and higher age; low SES only in the Chinese and being female only in the Vietnamese sample. Clinical relevance Incomplete anterior regions, Bimpaired^premolar or molar regions, and especially edentulousness can be considered significant risk indicators for food avoidance.

“…Of the nine articles included in the review, two reported differing diet and nutrition outcomes from the same RCT leaving both articles eligible for inclusion (Amagai et al 2017;Suzuki et al 2017). Therefore, eight separate studies were reported upon, involving data from 526 participants.…”

“…This approach has been explored in a number of studies in order to address diet and nutritional challenges in this growing population group with mixed evidence of impact (Bartlett et al 2013;W€ ostmann et al 2016). However, an increasing body of randomized controlled trial evidence supports the combination of oral rehabilitation coupled with a purposeful dietary intervention component amongst this population group (Bradbury et al 2006;Amagai et al 2017;Suzuki et al 2017); with reported improvements in dietary intake ranging from increases in fruit and vegetables to protein. Yet, fundamental gaps in understanding remain regarding the content, design and format of these dietary interventions, and how these characteristics might link to the outcomes of such dual interventions (i.e.…”

As natural teeth are lost, many older adults choose softer foods lacking in essential micronutrients and fiber, yet replacing missing teeth alone does not positively influence diet. Dietary intervention in combination with treatment to replace missing teeth is increasing, though understanding of effective intervention components is limited. This systematic review synthesized literature relating to oral rehabilitation coupled with dietary intervention in adults. The primary outcome was dietary intake; secondary outcomes pertained to oral health and dietary intervention characteristics including: theoretical basis and behavior change techniques (BCTs). MEDLINE, Web of Science, PubMed and CENTRAL were searched. Nine studies were included. Study designs were heterogeneous involving 526 participants. Narrative synthesis identified improvements in at least one aspect of participants' oral health (i.e. biting/chewing) alongside at least one positive diet/nutrition outcome post-intervention for all studies. F/V results were pooled for three studies using meta-analysis techniques resulting in a standardized mean difference (SMD) of 0.29 [CI À0.54, 1.12], p ¼ 0.49, but with marked heterogeneity (p ¼ 0.0007). Few interventions were theory-based and intervention components were poorly described. Overall, narrative synthesis indicated support for dietary intervention coupled with oral rehabilitation on diet. Meta-analysis was only possible with three studies highlighting limitations. Large-scale, appropriately described trial methodologies are needed. Trial registry: This review was prospectively registered with PROSPERO on the 11 July 2017 [CRD42017071075].

“…Although oral function and nutrition maintenance through a balanced diet are jointly critical to support daily physical activities, older adults tend to avoid foods with harder textures in favour of softer foods; even when masticatory efficiency was improved by new dentures, nutrition habits and status did not change . Dietary advice and instruction, however, could increase awareness and proper intake of nutrition . Deteriorated oral health, such as tooth loss, is associated with lower consumption of meat and vegetables and can result in less intake of protein and vitamins .…”

Background Preserving sufficient oral function and maintaining proper nutrition are essential to prevent frailty. Thus, we have developed “munchy” foods that contain harder textures and are rich in protein. Objectives This study aimed to test the effects of masticating textured foods on masticatory muscle activity in young and older adults. Methods Twenty young and 32 community‐dwelling older individuals participated in this study. After measuring oral function, we subdivided the older participants into normal and oral hypofunction (OHF) groups. Two test foods (meatloaf and chicken ball) were prepared to have a harder texture using specific ingredients (munchy) or not (control). The participants ate 10 g of the test foods in random order while being measured for masseter muscle activity with a surface electromyogram (EMG). We calculated the number of chewing cycles and integrated muscle activity of the masseter muscle from the EMG data and tested for differences by food texture or age group. Results The number of chewing cycles, mean EMG amplitude and integrated EMG activity was significantly higher for the munchy foods than for the controls for all groups. The integrated masseter muscle EMG activity was significantly increased in the normal older group than in the young group for both food types, but not significantly different between in OHF and young groups. Conclusions Our findings suggest that eating textured foods will lead to increased masticatory load and therefore increased muscle activity, especially in older adults. Application of textured food may change dietary habits in older adults.
