Actual (reported)Hong Kong and Japan are similar in terms of facing the super-ageing society. Maintaining oral function in elderly is particularly important because it affects social, physical and mental health to the people and to the society. By using technology seems to be one of the solutions in dealing with this. Thus, this project aims at using state-of-the-art Age-tech that have been used in Japan to implement "Oral Frailty" concept in Hong Kong. Through identifying oral biomechanical in elderly population, the investigators expect the situation can be improved, and the data analysed and collected can be useful and impactful that can influence the dental communities around Southeast Asia and the globe.

Actual (reported)Occlusal force assessment
The tooth models and occlusion will be taken to record the occlusal contact point, area and distribution, by intra-oral scanner (CEREC Omniscan / 3Shape), which is a standard practice at HKU. The occlusal force (N), occlusal contact area (mm2), maximum occlusal pressure (MPa), average occlusal pressure (MPa) of both sides are measured respectively, using occlusal pressure measurement film (Dental Prescale® II 50H, GC Corp) that is scanned with a dedicated scanner (GT-X830, Epson) with analysis software (Bite force analyzer, GC Corp).
The 1, 30, 90, and 120 days after recruitment. The investigators wanted to see if exercise would help oral muscle performance, there's a lack of data on this, so the investigator couldn't determine a change over time.
Masticatory efficiency
Gluco sensor (GS-II, GC Corp) will be used to quantitatively analyze the chewing ability 1. Rinse mouth for 3 times, 20s at least for each time. 2. Insert the test stick into GS-2, power on, and wait 6 seconds. 3. Chewing for 20s, use the preferred chewing side. 4. Rinse mouth with 10ml pure water and spit into the paper cup with a blue filter. 5. Discard the jelly residue in the filter, mix up the liquid (10s), dip the solution with a micro brush, point it on the test stick, wait for 6s for result reading, record reading: the concentration of sugar: \_\_\_\_mg/dL.

Tongue function assessment
Tongue pressure sensor (TPM-02, GC Corp) which indicates the tongue physical function, will be used to record the maximum tongue pressure (MPa) for 3 times of each participant, then tongue endurance will also be measured for 3 times by determining how long tongue could sustain 60% of their maximal pressure.
The 1, 30, 90, and 120 days after recruitment. The investigators wanted to see if exercise would help oral muscle performance, but there's a lack of data on improving this function, so the investigator couldn't determine a change over time.
Swallowing function assessment
The 1, 30, 90, and 120 days after recruitment. The investigators wanted to see if exercise would help oral muscle performance, there's a lack of data on this, so the investigator couldn't determine a change over time.
DDK rate

Dry mouth
A Chinese (Cantonese) version of dry mouth questionnaire consisting of 8-item xerostomia questions with a maximum total score of 32 points was used for subjective assessment, using a Likert format rated on a 4-point scale (1 not at all, 4 very much). Participants graded each aspect, with a higher score indicating impaired salivary function

Oral health-related quality of life
The Chinese-validated version of the Oral Health Impact Profile-14 (OHIP-14) questionnaire was used to assess oral health-related quality of life, using a Likert format rated on a 5-point scale (0 not at all, 4 very much) for 14 questions, higher scores represent the poorer oral condition-related quality of life, with a minimum 0 points and maximum 56 points.
