Abstract Objective: To document the long-term fate of maxillary incisors with resorbed roots after correction of the associated ectopic canines. Materials and Methods: The subjects were recruited from 107 children and adolescents age 9–15 years (mean 12.5 years) at initial registration, with 156 ectopically positioned maxillary canines. The children were referred to the specialist orthodontic clinic for consultation because of the risk of incisor root resorption. Of 51 patients contacted, 16 failed to attend. Eight of the remaining 35 were excluded because their lateral incisors had been extracted, leaving 27 subjects for follow-up registration. At initial consultation, all subjects had undergone radiographic examination, including computed tomography (CT) scans. At the follow-up consultation, the radiographic examination was limited to intraoral films. Results: No resorbed incisor was lost during the 2- to 10-year follow-up period. The resorptive lesions had undergone repair in 13 teeth, remained unchanged in 12 teeth and progressed in 7 teeth. In the 13 teeth exhibiting signs of repair, no resorption was detectable in 11 teeth and minor resorption was detected in 2 lateral incisors. At the initial registration, severe or moderate resorption had been diagnosed in 12 lateral and 5 central incisors, compared with 11 lateral and 6 central incisors at follow-up. In 10 subjects initially diagnosed with resorption of 13 incisors, the lesions were no longer discernible on intraoral radiographs at follow-up. Conclusions: Even in cases of severe resorption, the incisor roots show good long-term healing. Incisors with root resorption can be used in an orthodontic appliance system.

Delayed Eruption

Supernumerary teeth are relatively common in the oral cavity and are characterized by an excessive number of teeth. The term "mesiodens" refers to a supernumerary tooth located in the midline of the maxilla between the central incisors. Mesiodens may cause a variety of pathological complications such as impaction of the maxillary central incisors, tooth retention or delayed eruption of the permanent incisors,crowding, eruption within the nasal cavity, formation of diastema, intraoral infection, root anomaly, root resorption of adjacent teeth and cyst formation accompanied by bone destruction. Therefore it is recommended to follow-up with regular radiographic examination. Early diagnosis minimizes treatment needs and prevents associated complications. The present case, followed for 7 years, presented bilateral mesiodens resulting in delayed eruption of the permanent incisors and emphasizes the importance of multidisciplinary management and long-term follow-up.

Abstract This case report aimed to highlight the usefulness of cone beam computed tomography (CBCT) and its post-processing tools for the diagnosis, follow-up and treatment planning of invasive cervical resorption (ICR). A 16-year-old female patient was referred for periapical radiographic examination, which revealed an irregular but well demarcated radiolucency in the mandibular right central incisor. In addition, CBCT scanning was performed to distinguish between ICR and internal root resorption. After the diagnosis of ICR, the patient was advised to return shortly but did so only six years later. At that time, another CBCT scan was performed and CBCT registration and subtraction were done to document lesion progress. These imaging tools were able to show lesion progress and extent clearly and were fundamental for differential diagnosis and treatment decision.

Abstract Objective: To evaluate the long-term clinical and radiographic effects of maxillary incisor root resorption in cases of ectopic canines treated during the late 1970s and 1980s in Jönköping, Sweden. Subjects and Methods: The material comprised 55 incisors in 38 subjects. The posttreatment follow-up time was 13 to 28 years. All subjects underwent intraoral radiography, 33 were referred for computed tomography or cone beam computed tomography, and 24 also underwent clinical examination. The severity of incisor root resorption was correlated with clinical characteristics. Radiographs of the resorptive lesions were documented in detail and compared with intraoral radiographs taken immediately posttreatment. Results: Four incisors in three subjects had been lost, in part because of root resorption. Of the 36 incisors with root resorption, the lesions were unchanged in 26 teeth, improved in three teeth, and exacerbated in seven. In one case the resorption had progressed to pulpal exposure, necessitating endodontic treatment. For most of the incisors, the periodontal ligament was more clearly defined and the lamina dura showed improved trabeculation. The clinical characteristics of the incisors with resorption were not significantly different from those of sound incisors. Conclusions: In this long-term follow-up, most cases of incisor root resorption induced by ectopic maxillary canines did not progress and teeth with root resorption showed no clinically relevant symptoms. The prognosis for long-term survival of teeth with resorbed roots is good, but in cases where extraction is indicated, lateral incisors with severe root resorption should be extracted in favor of healthy premolars.

The purpose of this case report is to present a case of long-term retention of avulsed upper maxillary incisors with external replacement root resorption in a 15-year-old boy. The avulsed teeth, #11, 21, and 22, were stored under dry conditions for 40 min and replanted. Endodontic treatment was initiated after two weeks, and the nonrigid splint was removed after 3.5 months. A year after replantation of the teeth, replacement root resorption was detected radiographically. For the following 9 years, the resorption progressed slowly, but the teeth were maintained without any adverse effects on esthetic appearance. Under dry storage conditions, replacement root resorption was expected. In this case, the patient was a growing 15-year-old boy; thus, replantation was performed despite a possible poor prognosis. Consequently, root resorption progressed. Nevertheless, maintenance of the tooth crowns led to satisfying results for the patient both esthetically and psychologically. Ankylosis or replacement root resorption is a complication occurring after replantation of avulsed teeth, which could require additional treatment. However, in young patients, replantation could be considered to maintain the teeth until growth is complete.

Abstract Background Repair of a ventral hernia is increasingly being performed by a laparoscopic approach despite lack of good long term follow up data on outcomes. The aim of this study was to examine the long term performance of a polyester mesh and to assess its elastic properties in patients undergoing laparoscopic ventral hernia repair. Methods All patients being assessed for a ventral hernia repair between August 2011 and November 2013 were placed on a prospective database. Those undergoing laparoscopic repair with a polyester mesh were seen at clinic at one month and one year, while their electronic records were assessed at 34 months (range 24–48 months) and 104 months (range 92–116 months). In addition, CT scans of the abdomen and pelvis performed for any reason on these patients during the follow up period were reviewed by a consultant gastrointestinal radiologist. Mechanical failure testing of the mesh was also performed. Results Thirty-two of the 100 patients assessed for ventral hernia repair had a laparoscopic repair with a polyester mesh. Nineteen (59%) had CT scans performed during the follow-up period. No recurrence was recorded at 34 months, while three (9.4%) had a recurrence at 104 months. Two had central breakdown of the mesh at 81 and 90 months, while 1 presented acutely at 116 months after operation. Mesh had stretched across the defect by an average of 21% (range 5.7–40%) in nine patients. Mechanical testing showed that this mesh lost its elasticity at low forces ranging between 1.8 and 3.2 N/cm. Conclusion This study shows that late recurrence is a problem following laparoscopic ventral hernia repair with polyester mesh. The mesh loses it elasticity at a low force. This combined with degradation of mesh seems the most likely cause of failure. This is unlikely to be a unique problem of polyester mesh and further long-term studies are required to better assess this operative approach to ventral hernia repair.

AbstractObjectivesThe aims were to analyze the clinical features, response to treatment, prognostic factors and long-term follow-up of children and adolescents with differentiated thyroid carcinoma (DTC).MethodsEighty patients with DTC were studied retrospectively. All underwent total or near-total thyroidectomy, and in 75 cases, ablative iodine therapy was recommended. Patients were assessed periodically by tests for serum thyroglobulin levels and whole-body iodine scans. Age, gender, initial clinical presentation, histology, tumor stage, postoperative complications, radioiodine treatment protocol, treatment response, thyroglobulin (Tg), recurrence and long-term disease progression were evaluated.ResultsSeventy patients completed >2 years of follow-up (23 males, 47 females; median age: 14 years; range: 3–18 years). Sixty-two patients showed papillary DTC and eight, follicular DTC. Sixty-five percent presented nodal metastasis and 16%, pulmonary metastasis at diagnosis. Six months after first radioiodine treatment, 36.2% of patients were free of disease. Seven recurrences were documented. At the end of follow-up, overall survival was 100%, and 87.2% of patients were in complete remission. Nine patients had persistent disease. We found a significant association between stage 4 and persistent disease. Hundred percent of patients with negative Tg values at 6 months posttreatment were documented free of disease at the end of the follow-up. The analysis of disease-free survival based on radioiodine treatment protocols used showed no statistically significant differences.ConclusionsDTC in children and adolescents is frequently associated with presence of advanced disease at diagnosis. Despite this, complete remission was documented after treatment in most cases, with a good prognosis in the long-term follow-up. Negative posttreatment thyroglobulin and stage 4 at diagnosis were significant prognostic variables.
