Well-fitting dentures should be removed prior to testing spirometry

Please indicate if the following is true or false:

The potential risks associated with testing should always be weighed against the benefit of obtaining information about lung function.                                           

Impaired lung functions are generally graded in Occupational Health to quantify respiratory impairment/ disability for medico-legal purposes, and to optimise and standardise treatment:
