SROH was assessed by the following question. “Overall, how would you rate the health of your teeth and gums?” Potential responses ranged from “(1) excellent, (2) good, (3) fair, (4) not so good to (5) Poor.” In the analysis, the outcome was dichotomised: “(1) excellent and (2) good, (3) Fair” as “Good SROH,” and “(4) not so good and (5) Poor” as “Poor SROH”.
