Incremental cost of treatment and examination-$AUS36

Average cost of treatment was significantly related to the frequency of examination.

Restoration longevity/the number of restorations received were not significantly influenced by recall frequency.

More frequent attenders received more expensive treatments rather than more treatment.

DM FS Increment*

Difference in Examination time (min)Difference in Treatment time* (min)Difference in Total time (min)

The longer interval was associated with greater DMFS but this was not statistically significant.

There was no significant relationship between the length of interval and the treatment time.

Examination time and total time were significantly shorter for patients examined every 24 months than for patients examined every 12 months.

30% reduction in clinical time was obtained due to less time being spent on examinations.

Wang and Holst, 1995, Norway12.5 vs. 13.7 monthsDecline in number of decayed teeth
Difference in Clinical time (min) (examination+treatment)

Dental health in children did not change after extending recall intervals.

10% increase in interval length corresponds to a 14% reduction in dentists equivalent time.
