<p>The calcifying cystic odontogenic tumor (CCOT) is a benign cystic odontogenic tumor relatively uncommon and may be associated with other odontogenic lesions. This manuscript describes a case of CCOT associated with odontoma in a 9-year-old girl, who presented with a slight swelling along with prolonged retention of a maxillary primary central incisor. Radiographic examination showed a unilocular radiolucent lesion containing radiopaque material, associated with an unerupted tooth. Taking into consideration the clinical diagnostic of odontoma, an excisional biopsy was carried out. Microscopic examination established the diagnosis of a CCOT associated with odontoma. The association of these lesions is rare in individuals in the first decade of life, particularly involving mixed dentition, as outlined in this case. The patient remains under care with no clinical signs of recurrence.</p>

Compound Odontoma

Odontoma is defined as calcifying benign odontogenic tumor composed of various tooth tissues such as enamel, dentin, pulp, and cementum and representing the second most common odontogenic tumor of the jaw bones. These lesions are often associated with impacted permanent teeth. They are usually small, asymptomatic and diagnosed after routine radiographic examination. The aim of this work was to report a case of a compound odontoma in the anterior maxilla of a 35-year-old woman, which was causing the impaction of the maxillary left central incisor. A removal of the tumor was planned. An orthodontic approach was proposed as a surgical procedure for orthodontic traction of the impacted tooth. After 12 months, the clinical and radiographic examination revealed the eruption of the impacted incisor. The recommended treatment of compound odontoma is the complete removal of the tumour. An orthodontic approach may be indicated to correct any malocclusion or to perform the traction of the tooth, due to a possible impaction.

Odontogenic anomalies are frequently observed by pedodontists in their routine practice. Concomitant hypodontia and hyperdontia is a rare condition of unknown aetiology. CHH may occur in both the jaws and is more common in the permanent and mixed dentition. This article, describes a case of non-syndromic CHH in the mixed dentition. Genetic factors probably play an important etiological role in the co-occurrence of partial anodontia and supernumerary teeth. A 7 year old boy showed a conical mesiodens and missing right primary central incisor. Radiographic examination of the patient revealed presence of succedaneous permanent teeth.

SUMMARY A seven-year-old boy with enamel-dentin fractures on both maxillary central incisors presented to the Piracicaba Dental School–UNICAMP seven days after the trauma. At the clinical evaluation, there were no clinical signs of pulp exposure, neither tooth was mobile, and both affected teeth presented a positive response to sensitivity tests and a negative response for percussion and palpation. The radiographic examination showed an undeveloped root and opened apex for both teeth. Indirect pulp capping was performed on the left maxillary central incisor, followed by a direct restoration. After one month, the patient complained of pain in the left central incisor, which responded negatively to sensitivity testing. Pulp revascularization was performed only on this tooth and was followed for 18 months. During this period, the left maxillary central incisor did not recover sensitivity, although radiographic examination showed apical closure, a slight increase in root length, and the formation of a mineralized barrier between the root canal and sealing material. The technique achieved its goal of restoring biological aspects, function, and esthetics of traumatized teeth when using this multidisciplinary approach.

ABSTRACT The adenomatoid odontogenic tumor is a benign, non-invasive tumor and has a slow growth. Its preferred location is the anterior maxillary area, most often causing root displacement, more rarely resorption and mostly affects young women. Being asymptomatic, this injury is discovered upon routine radiographic examination, in which, in most cases, a unilocular, radiolucent image is observed and it may have some degree of calcification within the lesion. This work aims to report the case of a 14-year-old patient who attended the Lauro Wanderley University Hospital (UFPB), complaining of increased volume over a period of 8 months, in the region of non-vital tooth 21. The CT scan showed well-delimited unilocular, radiolucent lesion, with buccal cortex resorption. The proposed treatment plan involved enucleation, followed by peripheral ostectomy and bone graft with alloplastic materials. Because of its benign character, encapsulated and slow growing, the treatment of choice for adenomatoid odontogenic tumor is conservative, the surgical enucleation of the injury being advocated. The excised piece was sent for histopathological analysis, where the AOT diagnosis was confirmed. After 7 months, new bone formation was observed without signs of recurrence.

Patient Reported

Background Dilaceration, a developmental disturbance, is thought to be due to trauma leading to change in the position of the calcified portion of the tooth and the tooth is formed at an angle. Such an injury to a permanent tooth, resulting in dilacerations, often follows traumatic injury to the primary predecessor. A study by Patiletal, on Indian population reported the prevalence of very rare developmental dental anomalies and dilaceration was found to be only about 0.5% in prevalence. Case details A 9 year old male reported to the department of paediatric dentistry with complaint of missing central incisor in maxillary left arch. Radiographic examination revealed impacted maxillary left incisor with very unique and unusual extreme curve in root of same tooth giving it a characteristic U morphology. As the patient reported in mixed dentition stage, both the surgical, prosthodontic and pedodontic perspectives were kept in mind before planning for the treatment. Surgical removal was planned as it was not possible to save and place the tooth in the arch. Although surgical removal was challenging due to extreme curve and highly placed position of tooth, surgical removal was done successfully with roots and crown broken in two sections in spite of proper care during extraction procedure. Edentulous space was replaced with groper’s appliance considering mixed dentition stage of the patient after successful healing as per the pedodontic perspectives. Conclusion U shaped presentation of single rooted tooth is a one of the rarest findings. In children with age of interception, treatment should be planned wisely taking into consideration surgical, prosthodontic and pedodontic perspectives together. Key Words U shaped root, dilaceration, impacted tooth, surgical and pedodontic perspectives

The adenomatoid odontogenic tumor is a benign epithelial pathology that comprises 3 to 7% of odontogenic tumors. It has the characteristic of slow and progressive growth and almost no symptoms, being more frequent in women especially in the first two decades of life. Also, the anterior region of the maxilla is the anatomical location mostly affected. A white female patient, 16 years old, presented absence of the canine, first, and second maxillary premolars on the right side, prolonged retention of the right upper deciduous second molar, volumetric increase in the buccal and palatal alveolar ridge with extension to the bottom of the right maxillary vestibule, being diagnosed after the incisional biopsy as an adenomatoid odontogenic tumor. Considering the clinical and radiographic examination, it was decided to perform decompression of the lesion before performing enucleation and curettage.

Abstract Introduction/Objective Adenomatoid odontogenic tumor (AOT) is an uncommon benign odontogenic tumor representing 3 to 7% of all odontogenic tumors. This tumor was first reported as adeno-ameloblastoma by Bernier and Tiecke in 1950 as it was initially assumed to be a type of ameloblastoma. In 1969, Philipsen and Bern proposed the term adenomatoid odontogenic tumor which was subsequently adopted by WHO and became the accepted terminology for this tumor. AOT is classified as a tumor of odontogenic epithelium but occasionally abnormal hard tissues consistent with dentinoid material may also be present as part of the tumor. AOT tends to occur in younger patients and 50% of the cases are diagnosed in teenagers. It occurs twice as commonly in females and frequently involves the anterior maxilla. Radiographically, AOT can appear as a radiolucent or mixed lucent-opaque lesion and may be associated with an impacted tooth. Methods/Case Report We report two unusually large expansile lesions of AOT that presented in the mandible. In the first case, the tumor presented as an expansile radiolucent lesion involving the right posterior mandible in a 32 year old female. In the second case, the tumor presented as an expansile mixed lucent-opaque lesion involving the left anterior mandible in a 21 year old female. The clinical presentation, radiographic and imaging findings, histopathologic features and treatment of these two cases will be discussed. The recommended treatment for AOT is surgical excision. The prognosis is good as this tumor seldom recurs after excision. Results (if a Case Study enter NA) NA Conclusion AOT is considered to be a non-aggressive, non-invasive and slow growing benign neoplasm. It is usually discovered on routine radiographic examination as the lesion is usually small and asymptomatic at the time of diagnosis but occasional cases that are larger in size have been reported in the literature.

Maxillary Incisors

Clinically, supernumerary teeth are able to cause different local disorders and the most common one is impaction of maxillary incisors. Impacted maxillary incisors substantially affect esthetics, function, and self‑esteem of patients. Impaction of maxillary permanent incisor is a rare clinical entity in dental practice. Although impaction of a permanent tooth is rarely diagnosed during the mixed dentition period, an impacted central incisor is usually diagnosed accurately when there is delay in the eruption of tooth. Multiple treatment options are available for impacted incisors. Surgical-orthodontic treatment is one of the alternative option for the correction. Early diagnosis and management of supernumer¬ary teeth is important to prevent the need for more complex surgical and orthodontic treatment. Here, we present a report of two cases of impacted maxillary incisors and its management

Abstract Background Primary failure of eruption (PFE) is a hereditary condition, and linkage with variants in the PTH1R gene has been demonstrated in many cases. The clinical severity and expression of PFE is variable, and the genotype–phenotype correlation remains elusive. Further, the similarity between some eruption disorders that are not associated with PTH1R alterations is striking. To better understand the genotype–phenotype correlation, we examined the relationship between the eruption phenotype and PTH1R genotype in 44 patients with suspected PFE and 27 unaffected relatives. Sanger sequencing was employed to analyze carefully selected PFE patients. Potential pathogenicity of variants was evaluated against multiple genetic databases for function prediction and frequency information. Results Mutational analysis of the PTH1R coding sequence revealed 14 different variants in 38 individuals (30 patients and 8 first-degree relatives), 9 exonic and 5 intronic. Their pathogenicity has been reported and compared with the number and severity of clinical signs. In 72.7% of patients with pathogenic variants, five clinical and radiographic criteria have been found: involvement of posterior teeth, involvement of the distal teeth to the most mesial affected, supracrestal presentation, altered vertical growth of the alveolar process and posterior open-bite. In cases with mixed dentition (3), the deciduous molars of the affected quadrant were infraoccluded. Discussion The probability of an affected patient having a PTH1R variant is greater when five specific clinical characteristics are present. The likelihood of an eruption defect in the absence of specific clinical characteristics is rarely associated with a PTH1R mutation. Conclusions We report here that systematic clinical and radiographic observation using a diagnostic rubric is highly valuable in confirming PFE and offers a reliable alternative for accurate diagnosis.

A 2-year-old Maltese was presented with wobbly gait of the pelvic limbs. Based on imaging examinations, a diagnosis of congenital malformation at T5–T8 and severe kyphosis causing spinal cord compression at T6–T7 was made. Dorsal laminectomy and stabilization of T6 and T7 vertebrae were performed. As the size of the vertebrae was small and they were severely deformed, novel custom-made titanium implants were used for spinal stabilization. Clinical signs were resolved 2 weeks after surgery. Although radiographic examination 373 days after surgery showed slight loosening of implants, post-operative course remained uneventful. This report describes the use of novel custom-made titanium implants for spinal fixation surgery in a dog.
