Development of a Device that Identify Volatile Gases in Halitosis: Efficacy Assessment in a Sample of Elderly People

The proposed study aims to verify the effectiveness of developed device capable recognizing and measuring halitosis. This is a qualitative, descriptive exploratory research that will use experimental method for purpose creating verifying recognizes volatile gases in For design device, through analysis main components present these halimeters, best way build halimeter was sought based on Arduino, which composed RISC Microcontroller, uses C/C as programming language. C++ capture MQ-135 sensor selected. testing purposes, it happened sample institutionalized elderly residents city interior state Minas Gerais, composing 16 participants who met inclusion exclusion criteria. Data collection took place control group 3 (three phases), where, phase 1 application health condition questionnaire, 2 handling without proper mouth hygiene repetition however, performing hygiene. results reveal 100% are female with mean age 73,125 years old, between 60 94 old; 50% women have dental calculus, 56.3% visible biofilm 93.8% difficulties; functioning identified good regard expected, no failure during applicability exam any stages, evidencing assisting diagnosis halitosis; 94% did not express complaints examination 87% 3; stating most n=14 indicated halitosis only 5 halitosis, effectively demonstrating adequate care contributes absence pathological bad breath confirms proposed. It concluded possible attest fact an oral problem this population needs routine monitoring by their caregivers regarding condition; found be efficient due its characteristics, limitation, being able used diagnostic resource professionals different contexts.
