Spontaneous remission of internal root resorption during orthodontic treatment: A clinical follow-up report

While uncommon in orthodontics, the extraction of central incisors may be indicated when such teeth are of poor prognosis. This report details orthodontic treatment of a 13-year and 5-month-old Chinese female, who presented with Class II/1 malocclusion on a Class II skeletal jaw base relationship. Her maxillary central incisors were ankylosed and had undergone severe external root resorption following a previous traumatic episode. Orthodontic treatment involved removal of the maxillary central incisors and the mandibular first premolars. Pre-adjusted edgewise appliances with MBT prescription were used. To enhance anterior esthetics, prosthetic buildup of the four maxillary anterior teeth was performed before appliance removal. Tight intercuspation of teeth and optimal facial esthetics were achieved at appliance debond and maintained at 2-year follow-up.

External Apical Root Resorption

ABSTRACT Objective: The current study investigated the correlation between pulpal sensitivity to the electric pulp tester (EPT) and external apical root resorption (EARR) in four types of maxillary anterior teeth of fixed orthodontic treatment patients. Methods: In this prospective cohort study, 232 anterior teeth of 58 patients (mean age 18.96 ± 6.13 years) treated with fixed orthodontic treatment were examined. The EPT readings were recorded at twelve time points immediately before archwire insertion. Root resorption of four maxillary incisors were measured by means of parallel periapical radiographs at three time intervals (six months interval from the start) through design-to-purpose software to optimize data collection. A multiple linear regression model and Pearson correlation coefficient were used to assess the association of EPT values and observed EARR (p< 0.05). Results: The highest level of EPT measurement was recorded at initial visit, and then there was a decreasing trend in EPT level during treatment for the next six and twelve months. There was another increasing trend after six months till the finishing time of the treatment. There was a significant correlation between changes in root length and time of recording the root length (p< 0.001). There was significant positive correlation between changes in EPT level and amount of observed root resorption (p< 0.001). Conclusion: The relative decrease in electric pulp test level could be a diagnostic sign of root resorption during orthodontic treatment. Further studies with longer follow up are needed to confirm the current results.

The relation between orthodontic forces applied to deciduous teeth and the occurrence of root resorption, as a possible outcome of these forces, has not been studied to date. The aim of this work was to study root resorption in deciduous teeth of patients receiving orthodontic treatment. Twenty-four deciduous molars extracted for therapeutic purposes were studied: nineteen molars treated with light orthodontic forces and five untreated molars that served as control. Histological and histomorphometric studies were performed to determine the magnitude of root resorption. Location of root resorption in treated deciduous teeth was different from that of physiological root resorption. Extent and volume of root resorption were more extensive and deeper in treated than in untreated teeth. These results suggest that radiographic follow-up of deciduous teeth subjected to orthodontic forces would be useful to prevent root fractures.

Abstract Objective: To evaluate the perception of Greek and Swedish orthodontic practitioners regarding the possible occurrence and prognosis of root resorption occurring during orthodontic treatment and to estimate practitioners' approaches to the diagnosis of preexisting root resorption, screening of prevalence, and treatment planning approach when moderate or severe root resorption is present. Materials and Methods: Questionnaires were received from randomly selected Greek (n = 90) and Swedish (n = 106) practitioners. Topics of the questions included (a) the presence of history; (b) the radiographic evaluation of root resorption before, during, and after treatment; (c) the treatment approach of initial prevention and protocols in cases of radiographic diagnosis of root resorption during treatment. Results: Of the respondents, 47.1% of the Swedish practitioners and 32.3% of the Greek practitioners use periapical and panoramic radiographs to diagnose root resorption, mostly in the anterior region. Both groups recognize trauma, root form, and oral habits as predisposing factors. The majority of Swedish orthodontists perform radiographic follow-up in the first 6 months. In contrast, the Greek orthodontists perform it at 1 year or at the end of treatment. The treatment approach for root resorption that is most frequently used by Swedish orthodontists is altering the treatment plan, using light forces, and allowing resting periods, while the Greek orthodontists most frequently use lighter forces and reduce the total duration of the treatment. Conclusions: Because there is no specific approach offered in the literature, the prevention and treatment reassessment in cases of root resorption relies on individual practitioner perception.

Chief Complaints

Abstract The patient was a 24-year-old Japanese female. The chief complaints were crowding and masticatory dysfunction due to the missing right first molar. Her maxillary first premolars had been extracted when she was a primary school student. We planned orthodontic treatment with extraction of the mandibular first premolars and transplantation of the mandibular left first premolar into the maxillary right first molar area. We made a diagnostic setup model to initiate an appropriate treatment plan for the discrepancy in tooth size ratio. Following the diagnostic setup model, the space in the maxillary right first molar area was closed by a small amount of tooth movement, and a good occlusion was achieved. The patient had been in retention for 7 years, and the occlusion has been maintained very well during this time. In the follow-up, 10 years after autotransplantation, no signs of inflammatory or replacement root resorption were found, and marginal bone support appeared similar to that of neighboring teeth.

Management Protocol

External root resorption (ERR) is a highly prevalent, multifactorial problem frequently associated with orthodontic treatment. Treatment is complex due to the lack of solid knowledge regarding predisposing factors, systematic management for diagnosis and follow-up protocols or thefundamental theoretical bases of adequate imaging tools for each situation. This review describes the indications of the use of cone beam computed tomography (CBCT) and the factors related to its development and the characteristics of the techniques used in the diagnosisand monitoring of ERR in orthodontics. We compared the advantages and disadvantages of CBCT based on the risk/benefits. Methods: We have reviewed and summarized the information and the risk factors available on ERR in orthodontics and the use of CBCT in the diagnosis and follow-up of ERR with the aim of developing a management protocol. Likewise, CBCT is compared with other imaging techniques frequently used in ERR. The articles reviewed in this study coincide in terms of the advantages of precision of CBCT in the detection and linear and volumetric measurement of ERR associated with orthodontics over two-dimensional techniques. However, CBCT cannot completely replace other imaging techniques since its effectiveness is not significantly greater in cases with moderate ERR compromise. The use of CBCT should be optimized following specific criteria for its application.

ABSTRACT Objective: To present a patient treated with submerging autotransplantation (SA) of an immature premolar and subsequent orthodontic space closure (OSC) and to report a 10-year follow-up result. Case and Method: A 10-year-old boy had multiple missing premolars with an asymmetric pattern (maxillary right first and second premolars, teeth 14 and 15; maxillary left second premolar, tooth 25; and mandibular right second premolar, tooth 45). After considering several treatment options, tooth 35 with immature root development underwent SA into the missing site of tooth 15 at a depth 5 mm below the occlusal plane and was stabilized with sutures to create a symmetric missing condition of the premolars in the four quadrants. Results: Three months after autotransplantation, spontaneous eruption of the transplanted tooth was observed. Nine months after autotransplantation, presence of the lamina dura of the transplanted tooth was confirmed with a periapical radiograph. Active orthodontic treatment was initiated to reduce lip protrusion by closing the missing spaces of teeth 14, 25, 35, and 45 and to correct dental midline deviation. After 33 months of active orthodontic treatment, Class I canine and molar relationships were obtained. During the 10-year follow-up, the pulp vitality of the transplanted tooth was maintained without any pathologic findings, including root resorption or pulp canal obliteration. Conclusions: In a patient with lip protrusion and multiple congenitally missing premolars with an asymmetric pattern, SA of one premolar from the normal quadrant into the quadrant missing two premolars with subsequent OSC of the missing sites of the other premolars can be an effective treatment modality.

The Moment

Seventy primary molar teeth, carious exposed, symptom free, without any sign of root resorption in children aged from 3 to 6 years (main age 4.3yr) were treated with conventional pulpotomy procedures. Ferric sulfate 15.5% solution (applied for 15 second for 35 teeth) and formocresol solution (five minute procedure of Buckley's formula for next 35 teeth) have been used as pulpotomy agents. In both groups, pulp stumps were covered with zinc-oxide eugenol paste. Permanent restorations were stainless steel crowns. Clinical check up was every three-months and radiographic follow-up time was six and twenty months after treatment. Our results within this period revealed 100% clinical success rate in both groups. Radiographic success rate was in both groups 97.2%, while in 2.8% cases has shown internal root resorption. On the basis of these results, we can recommend ferric sulfate as a pulpotomy agent in primary teeth in substitution for formocresol at the moment.

ABSTRACT Objective: To evaluate the stability of nonsurgical miniscrew-assisted rapid maxillary expansion (MARME) in young adults with a transverse maxillary deficiency. Materials and Methods: From a total of 69 adult patients who underwent MARME followed by orthodontic treatment with a straight-wire appliance, 20 patients (mean age, 20.9 ± 2.9 years) with follow-up records (mean, 30.2 ± 13.2 months) after debonding were selected. Posteroanterior cephalometric records and dental casts were obtained at the initial examination (T0), immediately after MARME removal (T1), immediately after debonding (T2), and at posttreatment follow-up (T3). Results: Suture separation was observed in 86.96% of subjects (60/69). An increase in the maxillary width (J-J; 1.92 mm) accounted for 43.34% of the total expansion with regard to the intermolar width (IMW) increase (4.43 mm; P < .001) at T2. The amounts of J-J and IMW posttreatment changes were −0.07 mm (P > .05) and −0.42 mm (P = .01), respectively, during retention. The postexpansion change in middle alveolus width increased with age (P < .05). The postexpansion change of interpremolar width (IPMW) was positively correlated with the amount of IPMW expansion (P < .05) but not with IMW. The changes of the clinical crown heights in the maxillary canines, first premolars, and first molars were not significant at each time point. Conclusions: Nonsurgical MARME can be a clinically acceptable and stable treatment modality for young adults with a transverse maxillary deficiency.
