ABSTRACTExternal apical root resorption (ARR) is a common iatrogenic consequence of orthodontic treatment. One of the aims of this article is to present a brief overview of the literature, including; diagnosis and etiology, with emphasis on orthodontic forces to facilitate an understand of the prevention or management of ARR in orthodontic patients. We also present a long-term follow-up observation of severe ARR, including the last obtained cone beam computed tomography (CBCT) records, to demonstrate the effect of orthodontic forces on ARR.

This case report describes an external apical root resorption resulted from the unusual root morphology of the neighbouring tooth. A 28-year-old female was referred to the department of endodontics with a complaint of intense pain in her maxillary second premolar tooth. The clinical and radiographical evaluation revealed an external apical resorption in the mesial root of the maxillary first molar, which shows close proximity to the severely curved root of the premolar. A successful root canal treatment of the premolar was performed using anticurvature filing method. However, molar tooth received no curative treatment. One-year followup of the apical external resorption did not show any progression. External apical root resorption affecting single permanent tooth may be induced from the pressure exerted during the eruption of the adjacent tooth with unusual root morphology. The preferred approach for the management of such apical resorption cases includes long-term observation and no curative treatment.

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.

AIM: To conduct a retrospective comparative analysis of the efficacy and safety of epilepsy therapy with antiepileptic drugs. MATERIALS AND METHODS: The analysis of the treatment of 428 patients with epilepsy at the Childrens City Hospital No. 8 in Kazan, receiving antiepileptic drugs. RESULTS: It was found that valproic acid is more effective in the treatment of idiopathic generalized epilepsies compared to focal epilepsies (p = 0.0006). Valproate and carbamazepine were the most effective in the treatment of focal epilepsy with short- and long-term follow-up. Valproic acid is more effective than topiramate (p = 0.02), oxcarbazepine (p = 0.003), and levetiracetam (p = 0.003) in the treatment of focal epilepsy in short- and long-term follow-up. Carbamazepine is more effective than topiramate (p = 0.01), oxcarbazepine (p = 0.02), and levetiracetam (p = 0.001) in the treatment of focal epilepsy in long-term follow-up. It was revealed that more often they complained about side effects when using carbamazepine (63.2%). Levetiracetam was found to be better tolerated compared to valproate (p = 0.0006) and carbamazepine (p = 0.0006). Topiramate is better tolerated than carbamazepine (p = 0.02) and valproate (p = 0.03). Oxcarbazepine is better tolerated than carbamazepine in women (p = 0.04). CONCLUSIONS: When choosing an antiepileptic drug, it is necessary to be guided by the principle: first the basic, and then the drugs of the next generations, in the future, rely on information about the tolerability of the drug. It is necessary to evaluate the therapeutic effect of antiepileptic drugs with long-term observation, and use the criterion of complete absence of seizures as an indicator of the effectiveness of drugs.

Cleidocranial dysplasia (CCD) is a rare inherited skeletal syndrome. There is no consensus regarding the dental treatment strategy. Objectives. To report a rare case of cleidocranial dysplasia and to summarize the current clinical and dental features and prosthetic treatment of similar CCD patients reported in the literature. Results. A 17-year-old girl was diagnosed with CCD. She had a short stature with the ability to bring the shoulders under the chest. All remaining teeth were deciduous except the four first molars were permanent. The maxilla was hypoplastic with a relative prognathism of the mandible. The cone-beam computed tomography examination showed a distorted and incomplete root formation of the permanent teeth. She was treated with both, complete and partial, removable overdentures. PubMed was used for the literature research using the following keys words “Cleidocranial Dysplasia”[Mesh], “Prosthodontics”[Mesh], “Dental Care”[Mesh], “cleidocranial dysostosis,” and “dental treatment.” The retention of deciduous teeth was described in the majority of cases. All the patients had supernumerary teeth. The most used treatments were dental prosthetics and orthodontics. The fixed prosthetic implant was the most used type of prosthetic treatment. Among the 15 cases who specified the type of prosthetic treatment, seven patients received removable dentures. Prosthetics was indicated especially for aged patients. Conclusion. Removable prostheses are a good solution that rapidly restores esthetics and functions. The use of implants for these patients needs to be validated by a long-term follow-up.

Abstract Objectives: To investigate sensitivity, specificity, predictive values and accuracy of periapical radiography (PR) and Cone beam computed tomography (CBCT) for detection of external apical root resorption (EARR).Materials and Methods: Dog’s teeth with experimentally induced root resorption underwent or not root canal treatment (n = 62 roots). True positives (TP), false positives (FP), true negatives (TN) and false negatives (FN) in PR and CBCT diagnoses were determined using histopathologic findings as gold standard. Sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and diagnostic accuracy (TP + TN) in the diagnosis of EARR were calculated. Data was compared using chi-squared test (⍺= 0.05).Results: We found that PR detected EARR in 35% of roots and CBCT, in 47%. EARR was microscopically diagnosed in 50% (p = 0.03 comparison between PR and microscopy; p = 0.67 comparison between CBCT and microscopy). Overall, CBCT produced more accurate diagnoses than PR (0.93 for CBCT versus 0.70 for PR; p = 0.008). Interestingly, when data was stratified into small and large resorptions, PR and CBCT allowed identification of large resorption in 100% of the cases and showed the same accuracy. However, for small resorptions, PR showed an accuracy of 0.83, whereas CBCT showed an accuracy of 0.96 (p = 0.003).Conclusions: We demonstrated that CBCT showed higher accuracy to detect EARR. These findings shed light on the use of CBCT for detection of initial root resorption.Clinical relevance: Early identification of resorption allows a prompt treatment and reduces the risk of dental structure loss.

Somatosound (somatic tinnitus) is associated with vascular, musculoskeletal, respiratory, or temporomandibular joint disorders. Several studies of its management have been widely reported, but only few presented long-term follow-up results. The purposes of this paper are to review the causes and management, present cases with long-term follow-up, together with previously reported cases in literatures. We treated nine patients with somatosound of vascular, hematologic, endocrinologic, muscular, and cervical origin. Follow-up were conducted routinely, and the final results were collated in 3 to 11 years. Patients with non-life-threatening causes were given counseling and palliative management. Their tinnitus becomes tolerable, gradually decreased, and even disappeared. Patients with life-threatening causes were treated immediately. Among all, there were three cases which to the best of our knowledge, are the first reported of its causes. One case was caused by a compensatory of increasing blood flow in internal carotid artery (ICA) secondary to contralateral ICA stenosis. Another had a combination of anemia and an ipsilateral jugular bulb diverticulum. The tinnitus disappeared after the anemia treated. The last was patient with hyperthyroidism. The tinnitus disappeared by controlling the condition. Even when the causes are benign and the available treatments may carry risks, the patients should not be left unmanaged. Symptomatic treatment should be given, such as counseling, sound therapy, and palliative management. Our long-term observation indicated that overall outcomes are positive when the etiologies are identified early and managed properly.

Chronic kidney disease (CKD) is a common complication after liver transplantation (LT). Its prevalence with modern immunosuppression regimens, especially in children, is variable depending on the transplantation era. The study included 61 pediatric patients with at least 10 years of follow-up after liver transplantation remaining under constant care of the Department of Pediatric Surgery and Organ Transplantation. The analysis included several tests: estimated glomerular function (eGFR), results of screening for renal tubular defects and blood concentrations of basic immunosuppressive drug-tacrolimus. CKD was diagnosed in 3% of children at 12 years after LT. The maintaining of tacrolimus concentrations >4 ng/mL in long-term observation was associated with a significant increase of microalbuminuria. The presence of microalbuminuria, regarded as a risk factor of CKD, confirmed the necessity of regular comprehensive assessment of patients in long-term follow-up.
