Unicystic ameloblastoma (UAM) is a variant of intraosseous ameloblastoma that occurs as a single cystic cavity. This report describes a case of UAM of the mandible in a seven-year-old girl. The lesion radiographically mimicked a dentigerous cyst. Under the primary diagnosis of a dentigerous cyst, marsupialization was performed to erupt the first molar involved in the cystic lesion and to obtain a definitive diagnosis. The biopsy specimen revealed ameloblastoma. During careful observation, orthodontic treatment, which was performed to upright and promote the eruption of the first molar involved in the tumor, maintained the space needed for enucleation of the tumor. Finally, the second primary molar was extracted, and the lesion was enucleated at 3 years and 4 months after marsupialization. The results of the histological examination revealed UAM. Conclusively, the treatment course not only avoids a resection of the mandible but also induces eruption of the teeth involved in the tumor. Thus, the combination of conservative surgery and orthodontic treatment was effective in the management of UAM that mimics a dentigerous cyst.

INTRODUCTION: The dentigerous cyst is a developmental odontogenic cyst, whose therapeutic approach depends on the size of the lesion. This paper describes the treatment performed on a 14-year-old male patient who presented with a large dentigerous cyst on the permanent mandibular left second molar. CASE REPORT: The permanent mandibular left first molar was extracted, and the lesion was decompressed and marsupialized by excision of the overlying mucosa, opening a window into the cystic cavity and suturing an acrylic resin drain to the oral mucosa. The specimen removed during surgery confirmed the diagnosis of a dentigerous cyst. Within ninety days of surgery, there was a significant reduction in lesion size. Orthodontic treatment was then started, and included traction of the impacted tooth and opening of adequate space with a fixed appliance, providing favorable tooth alignment and leveling. CONCLUSION: Marsupialization and orthodontic traction should be considered when planning the treatment of a dentigerous cyst, mainly in young patients with large lesions, to avoid damage to the surrounding structures.

Agenesis of mandibular second premolar is reported to be 2.4–4.5%. The diagnosis can be set on at average 9 years of age. Early treatment in the form of extraction of the second primary molar and in some cases also the remaining three second premolars and comprehensive orthodontic treatment are often a good treatment solution. In vertical deep bite cases, cases with spacing in the dental arch, mandibular posterior rotation and for extractions disadvantageous growth pattern, a treatment with retaining of the primary molar must be taken in consideration. When there is no or minor infraocclusion, root resorption less than half of the root length, and no caries or fillings at the age of 12–13 years, there is a good prognosis for longtime survival of the primary molar.

Introduction. A dentigerous cyst is a pathological lesion associated with the crown of the unerupted or impacted tooth. Decompression is proposed as the initial treatment for large cysts, especially in younger patients. The aim of this article was to present clinical, radiological, histopathological, and therapeutical aspects of the large dentigerous cyst in the maxilla. Case report. A 12-year-old boy with a large dentigerous cyst in the maxilla was referred to our clinic. A dentigerous cyst was associated with the crown of the unerupted maxillary left canine. Management of the cyst included initial decompression with biopsy, followed by secondary enucleation after 9 months and orthodontic treatment. Histopathological examination confirmed the definitive diagnosis of the dentigerous cyst. Conclusion. Initial decompression with a subsequent enucleation proved to be an effective treatment choice for the large dentigerous cyst.

Relevance. To study the incidence of different types of resorption of multirooted primary teeth, to specify indications for deciduous molar extraction to prevent eruption abnormalities of permanent posterior teeth in mixed dentition.Materials and methods. Root resorption of 375 multirooted primary teeth (166 first primary molars and 209 second primary molars) was studied on panoramic X-rays of 60 children (30 girls and 30 boys) aged between 7 and 15. Illustrated classification by T.F. Vinogradova (1967) improved by authors was used to determine type and degree of root resorption of multi-rooted primary teeth. Received data were described with absolute values of number of cases and percentage. Chi-square was used to detect differences in sign incidence rate between groups, p<0.05 was considered statistically significant.Results. There were no statistically significant gender differences (p>0,05) in type and degree of root resorption of multirooted primary teeth. Type A resorption prevailed and constituted 53.3% of all primary molars. Disturbances in root resorption of multirooted primary teeth in mixed dentition were related to health condition of primary teeth. Transition of even resorption to unven was considered a risk factor of delayed eruption and aberrant position of permanent teeth, and indication for extraction of a primary molar in question. Conclusions. 1) Even root resorption (type A) was detected in 53.3% of primary molars in mixed dentition by orthopantomography. 2) Transition from even resorption of primary molar roots to uneven resorption was associated with eruption deviations and delayed premolar eruption. 3) Timely extraction of primary molars with uneven root resorption facilitated correct eruption of premolars and increased effectiveness of secondary prevention of malocclusion in children.

Abstract A consecutive series of 50 diagnostic cerebral biopsies carried out over a 12-year period (1960 to 1972) at The Neurological Institute of New York is reported. The goal of the biopsy was to acquire a definitive diagnosis to aid the patient, counsel the family, and advance scientific knowledge. General indications for biopsy were either chronic bilateral cerebral findings associated with progressive dementia or profound retardation or acute unilateral cerebral findings, usually associated with signs of meningoencephalitis. Four patients were not suitable for analysis, leaving 46 patients to be surveyed. Diagnostic neuropathological features were judged to be present in 17 specimens (37%). Abnormal but not diagnostic pathological changes were found in 22 specimens (48%). Thus, 39 specimens (85%) displayed some abnormality. No apparent neuropathological changes were present in 7 specimens (15%). These findings correspond favorably with the results of others and suggest that a certain “irreducible minimum” of normal biopsies occurs with the techniques utilized. Fourteen (30%) of the patients were known to be alive at the conclusion of the study. Twenty-two patients (48%) had died, but necropsy findings were available for only 10 of these. Except in 2 cases in which biopsies had been normal, no discrepancy was noted between the basic neuropathological changes found at necropsy and those of the biopsy specimen. One death could be directly attributed to the procedure, and total morbidity and mortality was approximately 13%. The authors recommend that any biopsy program should be organized at an institutional level to take into account the patient's special illness and the capabilities of that institution. In addition, suitable material must be forwarded to appropriate experts who have the knowledge and facility to make full use of biopsy material.

Chapter 3 discusses cancer diagnosis, risk stratification, and therapeutic choices in children and young people. Radiological investigations support the diagnosis and provide staging information for accurate risk stratification. Interventional radiology is useful for obtaining tissue for pathological examination. Histopathology and molecular studies define the precise tumour type and subtype and are used to confirm or rule out the presence of metastatic disease. Post-operative histopathology defines the extent of spread and is important for the staging of some tumours. Together, these findings inform multidisciplinary team discussion and help to identify the best treatment schedule. A significant proportion of cancers have a genetic basis, and it is important to identify these from the family history, predisposing syndromes, or tumour type. Modern molecular genomic techniques have made definitive diagnosis easier. Some genetic conditions lead to increased radiosensitivity and may predispose the patient to excessive radiation-related morbidity and a high risk of second primary tumours.

Objectives: Optimal restoration of endodontically treated teeth is very important for the durability of the endodontic treatment. The focus of this study was to evaluate the fracture strength and microleakage of composite endocrowns compared with Class II composite restorations in endodontically treated primary molar teeth. Materials and Methods: 48 extracted second primary molars were divided into 2 groups. Group 1 (control): teeth with Class II and endodontic access cavities restored with G-aenial composite; group 2: endocrown restorations with G-aenial composite. After completing restorative procedures, teeth were subjected to thermal cycling (500 cycles). Compressive loading was applied to half of the samples, although the other half were immersed in 0.5% basic fucsin solution for 24 h, sectioned, and examined for dye penetration under stereomicroscope. Data were subjected to statistical analysis by the Mann-Whitney U test (α = 0.05). Results: The fracture strength of endocrowns (1741 ± 379.35 N) was significantly higher than that of the control group (1126.5 ± 405.39 N) ( P < .05). No statistical difference was found in microleakage between the 2 groups ( P > .05). Conclusion: Endocrown preparation increases the fracture strength of the final composite restoration when used in primary molar teeth. Composite endocrown restorations can be a practical and an esthetic option for restoring endodontically treated primary molar teeth.
