Contribution of cone beam computed tomography to the detection of apical root resorption after orthodontic treatment in root-filled and vital teeth

Abstract

Objective: To investigate whether root-filled teeth are similar to vital pulp teeth in terms of apical root resorption (ARR) after orthodontic treatment. Materials and Methods: An original sample of cone beam computed tomography (CBCT) images of 1256 roots from 30 orthodontic patients were analyzed. The inclusion criteria demanded rootfilled teeth and their contralateral vital teeth, while teeth with history of trauma had to be excluded to comply with exclusion criteria. CBCT images of root-filled teeth were compared before and after orthodontic treatment in a split-mouth design study. Tooth measurements were made with multiplanar reconstruction using axial-guided navigation. The statistical difference between the treatment effects was compared using the paired t-test. Results: Twenty posterior root-filled teeth and their contralaterals with vital pulp were selected before orthodontic treatment from six adolescents (two boys and four girls; mean [SD] age 12.8 [1.8] years). No differences were detected between filled and vital root lengths before treatment (P 5 .4364). The mean differences in root length between preorthodontic and postorthodontic treatment in filled-and vital roots were 20.30 mm and 20.16 mm, respectively, without any statistical difference (P 5 .4197) between them.Conclusion: There appears to be no increase in ARR after orthodontic treatment in root-filled teeth with no earlier ARR.

Comparison of Orthodontic Root Resorption of Root-filled and Vital Teeth Using Micro–computed Tomography

“…Castro et al 12 conducted a study similar to the present study. In their study, 30 subjects with at least one root-filled tooth and cone-beam computed tomography (CBCT) images before and after treatment were included.…”

“…In the literature, the results of studies investigating OIEARR in root-filled teeth are controversial. Some studies [9][10][11] reported that root-filled teeth are a risk factor for OIEARR, whereas others [12][13][14][15][16][17] concluded there is no difference in terms of OIEARR between vital and root-filled teeth. In contrast, there are also many studies [18][19][20][21][22][23][24][25] reporting less OIEARR in rootfilled teeth than in vital teeth.…”

Penyerapan Akar Gigi Apeks Luaran Hasil Rawatan Ortodontik Pada Enam dan 12 Bulan

“…Walau bagaimanapun, kajian terhadap kesan jangka masa panjang rawatan ortodontik menunjukkan tiada perbezaan yang ketara dalam kejadian karies, penyakit periodontal atau kehilangan gigi antara individu yang mendapatkan dan tidak mendapatkan rawatan ortodontik (Thomson 2002) . Kesan rawatan ortodontik yang paling ketara adalah penyerapan akar gigi (Castro et al 2015(Castro et al , 2013Lund et al 2010). Antara penyerapan akar gigi yang paling kerap berlaku semasa rawatan ortodontik adalah jenis penyerapan akar apeks luaran (PAAL) (Topkara et al 2012).…”

Effect of Self-ligating on Bone Density and Root Surface in Maxilla and Mandiblec

“…Different types of forces Paper extracted from Doctor thesis entitled "Effect of Self versus Conventionally Ligating Orthodontic Brackets on Root Surface and Bone Density" and magnitudes were compared in the literature (14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26) to decrease the amount of root resorption. Apical root resorption was compared (27,28) in vital versus endodontically treated teeth after orthodontic treatment. Also, the extent of external root resorption was compared in asthmatic patients versus medically free patients after fixed orthodontic treatment (29) .…”
