There is growing international interest in identifying the effects of ageing on oral health and appropriate strategies for managing disorders. The Japanese Society Gerodontology (JSG), as official representative researchers clinicians interested geriatric dentistry Japan, makes several recommendations concept "oral hypofunction."This study proposes diagnostic criteria management to reduce risk hypofunction among older people.We define a presentation 7 signs or symptoms: uncleanness; dryness;...
In this study, a cellulose acetate (CA) membrane is formed as an interference rejection on glucose sensor to measure in saliva. Glucose saliva successfully measured vivo without any pretreatment of human A mouthguard (MG) developed monitor salivary glucose, which reported be correlated with the blood level. Salivary components ascorbic acid (AA) and uric (UA) hinder accurate measurement concentration CA-coated electrodes are prepared investigate membrane. To hydrogen peroxide, reaction...
To enable easy assessment of oral frailty; that is, an overlapping slight decline in multifaceted function, any setting, we developed the frailty five-item checklist (OF-5), and examined its predictive validity for increased risks physical frailty, disability mortality among community-dwelling older adults.
Aim This cross‐sectional study had two aims: to assess the prevalence of oral frailty (OF), according Oral Frailty 5‐Item Checklist (OF‐5), among community‐dwelling older adults; and examine associations frailty, dietary variety, social engagement, physical frailty. Methods We pooled data from population‐based studies (the Otassha Study Itabashi Longitudinal on Aging). With OF‐5, OF is characterized by presence or more following: (i) fewer teeth, (ii) difficulty in chewing, (iii) swallowing,...
The purpose of this study was to evaluate the fabrication a complete denture using CAD/CAM system. Cone beam CT used measure and artificial teeth. After 3D image structured CAD software, we factored out teeth obtained base image. A machining center cut an acrylic resin block, fabricated base. were bonded cement. digitizer digitized denture. We measured deviations between master data average from 0.50 mm for occlusal surface. This present indicates that it is possible fabricate
A new trial method for complete dentures using rapid prototyping (RP) was compared with the conventional method. Wax were fabricated 10 edentulous patients. Cone-beam CT used to scan wax dentures. Using 3D computer-aided design software, seven denture images different artificial teeth arrangements made and per patient accordingly. Two prosthodontists performed a try-in one both RP methods. The patients rated satisfaction methods visual analogue scale. Satisfaction ratings Wilcoxon...
Aging and sarcopenia reduce not only body strength, but also the strength of swallowing muscles. We examined how aging affect tongue pressure jaw-opening force.A total 97 older adults (97 men, mean age 78.5 ± 6.6 years; 100 women, 77.8 6.2 years) were enrolled. Classification was based on Criteria Asian Working Group for Sarcopenia. To investigate which variable between a significant independent force, multivariate linear regression analysis carried out.The 26.3 7.8 kPa in men 24.6 7.2...
This study evaluated the effects of differences in printing directions stereolithography (SLA) three-dimensional (3D)-printed dentures on accuracy (trueness and precision). The maxillary denture was designed using computer-aided design (CAD) software with an STL file (master data) as output. Three different (0°, 45°, 90°) were used. Photopolymer resin 3D-printed (n = 6/group). After scanning all dentures, data saved/output files (experimental data). For trueness, experimental superimposed...
Motor functions of masticatory organs such as the tongue, lips, cheeks and mandible are known to deteriorate with age, thereby influencing performance. However, there few reports on relationships between tongue lip To investigate relationship comprehensive performance, by evaluating crushing, mixing shearing abilities in young dentate adults. Participants comprised 51 adults a mean age 25 years. Maximum pressure oral diadochokinesis were measured evaluate functions. A multiple sieving method...
This study evaluated the influence of illuminance and color temperature ambient light on trueness, precision, scanning time a digital impression.Master data were acquired with high-accuracy coordinate-measuring machine. The was set at 0lux, 500lux, 2500lux light-emitting diode (LED). Using conversion filter, 3900 Kelvin (K) (yellow), 4100K (orange), 7500K (white), 19,000K (blue). There thus total 12 possible lighting conditions. reference model scanned five times under each condition by an...
Producing tongue pressure (TP) by pushing the against palate consists of lifting muscles and elevating floor mouth via suprahyoid muscle contraction. Though studies have shown that tongue-pressure resistance training (TPRT) increases function, none focused on function enhancements. Our study aimed to verify whether TPRT improves both hyoid movement during swallowing.Eighteen patients (mean age: 76.8±6.2 years) with presbyphagia presenting symptoms such as coughing choking were enrolled. All...
We aimed to assess the crystallography, microstructure and flexural strength of zirconia-based ceramics made by stereolithography (SLA). Two additively manufactured 3 mol% yttria-stabilized tetragonal zirconia polycrystals (3Y-TZP: LithaCon 3Y 230, Lithoz; 3D Mix zirconia, 3DCeram Sinto) one alumina-toughened (ATZ: ATZ, were compared subtractively 3Y-TZP (control: LAVA Plus, 3M Oral Care). Crystallographic analysis was conducted X-ray diffraction. Top surfaces cross-sections subsurface...
The purpose of this study was to investigate the relationship between masticatory performance as determined using a colour-changeable chewing gum and mandibular movements. Subjects comprised 45 fully dentate adults (23 men, 22 women; mean age, 28·1 years). chewed for specified number strokes (20, 40, 60, 80, 120 or 160 strokes) without any instructions side. A colourimeter used measure L*, a* b* values (CIE-L*a*b* colour system) gum, then difference two colours in CIE-L*a*b* space (ΔE) each...
Previous studies have reported a relationship between masseter muscle thickness and tooth loss or limb thickness. However, it is not yet known whether related to appendicular skeletal mass, grip strength. The purpose of this study was determine which the two variables-tooth mass index-is more strongly thickness, identify suitable indicator decreasing in healthy elderly individuals.Grip strength, walking speed, body weight, index, loss, at rest during contraction were determined 97...
