Orthodontic debonding and tooth sensitivity of anterior and posterior teeth.
OBJECTIVES
To assess whether orthodontic debonding and onset of tooth sensitivity were related and if anterior and posterior teeth showed different sensitivity.


MATERIALS AND METHODS
40 patients were divided into a trial group (group 1, at the end of the multibracket treatment) and a control group (group 2, not under treatment). After the application of compressed air and cold water to mandibular incisors and first molars, participants were asked to report the pain felt for each tooth using a 100-mm visual analogue scale. In group 1, assessment was performed just before debonding (T0), immediately after completion of debonding (T1) and 7 days after (T2). In group 2, values were assessed at the beginning of a follow-up visit (T0), at the end of the same visit (T1) and 7 days after (T2).


RESULTS
Considering overall teeth, statistical analyses showed significantly higher values in the trial group at T1 after both stimuli, especially after cold water, besides a significant difference between T0 and T2 values in the same group. Anterior teeth showed significantly higher VAS scores than posterior after the two thermal stimuli, except after air stimulation in group 1 at T2 and in group 2.


CONCLUSIONS
Orthodontic debonding leads to sensitivity to thermal stimuli especially in the anterior teeth, however pain level is restored within 7 days.
