Orthodontic debonding and tooth sensitivity of anterior and posterior teeth:

Abstract

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.

Comparative Evaluation of Different Numerical Pain Scales Used for Pain Estimation during Debonding of Orthodontic Brackets

“…Contrary to our finding, Nehir et al in their study found lesser VAS score in the lower arches away from where debonding started and explained this correlation with "monotony factor" [19], which means that patient can lose interest in the procedure after the first few teeth are debonded [3]. One finding that has been previously reported in a similar context is that orthodontic debonding usually leads to enhanced tooth sensitivity mostly in the anterior region but it gradually subsides in the next few days [32]. To this effect, desensitizing agents can be applied to help reduce pain during the period after debonding [33].…”

Siloranes–Suitability of a Novel Adhesive for Orthodontic Bracket Bonding

“…Optimal shear bond strength for orthodontic bonding should allow for little bracket failures during treatment as well as easy debonding at the end of treatment to avoid hypersensitivity due to bracket removal [26]. The shear bond strength measured for the adhesion of Filtek Silorane to unground bovine enamel was lower than the minimum forces recommended by Reynolds [27].…”

Management of Gingival Bleeding in Periodontal Patients with Domiciliary Use of Toothpastes Containing Hyaluronic Acid, Lactoferrin, or Paraprobiotics: A Randomized Controlled Clinical Trial

“…For instance, other bacterial strains deserve to be evaluated. Finally, due to the remineralizing effect of the zinc hydroxyapatite contained in the products, the action of the tested experimental toothpastes deserves to be evaluated also in lesions occurring in patients under active orthodontic treatment [28].…”
