Table 5.

Mortality table for the success of ETT. The number of terminal events equals the number of teeth lost in each interval

Interval start time (years)	Number of teeth in each time interval. Success	Number of teeth withdrawn during this interval	Number of teeth exposed to risk. Success	Number of terminal events. Success	Probability of surviving. Success (%)	Cumulative Success at the end of each interval	95% CI of cumulative success proportion
