Table 2. Need variables included in regression modeling *

Disease & tissue damage	Oral pain & discomfort	Oral functional limitation due to problems with teeth, mouth, or dentures	Oral disadvantage due to problems with teeth, mouth, or dentures	Self-rated oral health
Self-reported measures Broken filling Tooth fracture Cavities Abscessed tooth Infected or sore gums Bleeding gums Loose tooth Teeth stained or look bad Bad breath Measured by clinical examination Number of remaining teeth Root fragments Dental decay (caries) and restorations (fillings) Fractures of restorations Tooth fractures Severe root surface defects Severely loose teeth Periodontal attachment loss	Toothache pain Dental sensitivity	Difficulty speaking or pronouncing words Chewing difficulty	due to disease & tissue damage... Avoided laughing or smiling Avoided talking Been embarrassed by appearance due to pain... Trouble sleeping Kept from doing normal daily activities due to function... Avoided chewing hard things Been prevented from eating foods Avoided eating with others	Self-rated oral health Satisfaction with chewing ability Satisfaction with dental appearance Perceived need for care - yes, for a routine check-up - yes, due to a specific problem - no, in good shape now - no, have problem, but can wait

* All need variables were measured at baseline and at 6-monthly intervals thereafter, with the exception of those measured by direct clinical

examination, which were measured at baseline and 24 months only.
