Abstract
Ectopic teeth are an eruption disorder in which teeth are located in anatomical structures where, physiologically, they should not occur. An ectopic tooth is a very rare phenomenon, affecting approximately 0.5% of the canine population, and few descriptions of the treatment of such teeth in dogs can be found in the available literature. This article describes the diagnostic and therapeutic handling of cavities following extraction of ectopic teeth in nine dogs. The cases are subdivided into uncomplicated (when the ectopic tooth was encapsulated in the surrounding connective tissue, without lysis of the bone around the tooth) and complicated (in which, in addition to the presence of the ectopic tooth, a dentigerous cyst had formed). Four cases of complicated ectopic teeth are described in more detail. In this study, special attention was paid not only to the technique of tooth extraction itself but also to the method of securing and healing large bone defects after the extraction using hydroxyapatite curdlan polymer. Owing to the plastic properties of the bone substitute preparation, it was possible to implant the material without enlarging the bone defect created during the tooth extraction. Control radiographs showed features of bone regeneration, and clinical examination at both the early and late stages revealed no postoperative complications.

Abstract
Impacted teeth are those that fail to erupt at the typical age of eruption and remain enclosed in the maxilla or mandible, partially or completely surrounded by bone or soft tissues. Among these, third molars experience the highest incidence of impaction, with maxillary canines and mandibular bicuspids following closely. A 23-year-old female presented to the orthodontics department, expressing concerns about spacing issues in her upper and lower front teeth. During the orthodontic planning process and radiological assessment, two impacted teeth, specifically one primary molar and one permanent premolar, were identified in close proximity to the mental nerve. Both teeth were subsequently extracted with success. This case report underscores the importance of a thorough preoperative radiographic evaluation of the mandibular canal and foramina. Additionally, it stresses the necessity for dissection to prevent unintended injury to the mental nerve during the extraction of the impacted mandibular premolar, which can result in paresthesia affecting the lower lip, mandibular labial gingiva, and chin.

Frequency and Local Etiological Factors of Impaction of Permanent Teeth among 1400 Patients in a Greek Population. Dent J (Basel) 2022; 10:dj10080150. [PMID: 36005248 PMCID: PMC9406841 DOI: 10.3390/dj10080150] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/02/2022] [Revised: 07/25/2022] [Accepted: 08/09/2022] [Indexed: 11/19/2022] Open
Abstract
Background: The purpose of this study is to analyze the frequency of impaction of permanent teeth, beyond the third molars, and to highlight the factors causing this condition. Methods: Panoramic radiographs of 1400 patients that sought orthodontic treatment in private practice were retrieved and examined. All teeth that had not been erupted at the time of the examination while their root formation was completed were considered impacted. Results: In total, 212 out of 1400 patients had at least one impacted tooth (15.14%). The highest incidence of tooth impaction was in the canines of the maxilla, followed by the central incisors of the maxilla, the second molars of the mandible and the second premolars of the mandible. The most common etiological factors responsible for the impaction were the ectopic eruption pathway, loss of space in the arch, the ankylosis of the deciduous teeth and the presence of supernumerary teeth. Conclusions: Tooth impaction is frequently seen in everyday orthodontic practice. The upper canines are the teeth most frequently associated with impaction and failure of eruption. It is important to diagnose cases of impaction early on and identify the etiological factors in order to achieve immediate and effective treatment per patient.

Abstract
Impaction of the tooth in primary dentition is very less common than the permanent dentition. Impaction of teeth in primary dentition may create various problems in occlusion and also in developing dentition. Clinical and radiographic evaluation of such cases may benefit the patient as well as the clinician. Among primary tooth impaction cases, second primary molars are not frequently reported along with late formation of its succedaneous tooth. Nevertheless, the purpose of this report was to describe a case of a rare entity of reverse dentition caused by the impaction of the mandibular primary second molar associated with delayed formation of the second premolar.

Abstract
Primary impaction of primary teeth might be due to genetic predisposition or physical disturbance including odontoma, supernumerary tooth, and crowded tooth. Among them, calcific deposit or odontoma is commonly associated with primary dentition. Early diagnosis and treatment is the key to prevent complications. However, results of treatment may vary depending on the condition of unerupted tooth. Here we report two clinical cases of unerupted primary mandibular second molars with physical barriers such as compound odontoma and calcific deposit focusing on diagnostic means and the importance of early treatment of these lesions.

Abstract
Odontomas represent the most common type of odontogenic benign jaws tumors among patients younger than 20 years of age. These tumors are composed of enamel, dentine, cementum, and pulp tissue. According to the World Health Organization classification, two distinct types of odontomas are acknowledged: complex and compound odontoma. In complex odontomas, all dental tissues are formed, but appeared without an organized structure. In compound odontomas, all dental tissues are arranged in numerous tooth-like structures known as denticles. Compound odontomas are often associated with impacted adjacent permanent teeth and their surgical removal represents the best therapeutic option. A case of a 20-year-old male patient with a compound odontoma-associated of impacted maxillary canine is presented. A minimally invasive surgical technique is adopted to remove the least amount of bone tissue as far as possible.

Abstract
Tooth impaction is defined as any tooth that fails to erupt into a normal functional position and remains unerupted beyond the time at which it should normally erupt. Reports of impaction and eruption failure in primary teeth are relatively rare compared to permanent teeth. We report 2 rare cases where the second premolar was located on the occlusal side of the impacted mandibular second primary molar. In the first case, the succedaneous permanent tooth erupted after extraction of the primary tooth, fenestration, and traction. In the second case, the succedaneous permanent tooth erupted without fenestration or traction. Although the etiology of the tooth displacement was unknown in both cases, inhibition of the eruptive movement of the primary molar may have been associated with displacement of the succedaneous permanent premolar.

Abstract
The prevalence rate of impacted primary teeth is rare, still we can see impacted teeth in ectodermal dysplasia anhydrotic (EDA), endocrine deficiencies, metabolic disorders and local factors like cysts, tumors, trauma and thickened overlying bone or soft tissue. In cases of EDA, delayed tooth eruption is one of the characteristic finding. Present case report related to a rare case of primary teeth impaction of a 3 years old male child along with EDA. Intraoral examination and radiographs confirmed impacted primary maxillary and mandibular centrals and mandibular lateral incisors. Treatment carried out was surgical exposure of impacted primary teeth, then after patient was followed up for regular visits to check eruption status of the teeth.

Abstract
An odontoma is usually found in the surrounding area of the unerupted permanent tooth bud and rarely adjacent to the primary central incisor This report presents a case of an unerupted malformed primary central incisor, histologically diagnosed as a compound odontoma. A 5.5 year-old healthy boy presented with an unerupted maxillary left primary central incisor and mild gingival buccal swelling. No history of traumatic injury was recorded. Radiological examination revealed a tooth-like mass with a partially developed root and a malformed crown in the area of the left primary central incisor Delayed development of the successor left permanent incisor in comparison to the right one was noted. The rational for early surgical intervention to enable normal development and eruption of permanent incisors is described. Clinical and radiographic diagnoses as well as several etiological factors and a differential diagnosis are considered and reviewed.

Abstract
Retrospective investigations of odontomas in Japanese children and one recurrent case were carried out. Thirty-nine cases of odontoma in 38 children were treated in the Paediatric Dentistry Clinic of Niigata University Dental Hospital between September 1979 and December 2002. The patients consisted of 23 males and 15 females and their ages ranged from 1 year 2 months to 14 years old. The chief complaints were delayed tooth eruption in 19 cases (five: primary teeth, 14: permanent teeth), retention of primary teeth in 11, incidentally found on the radiographic examination in eight cases, and swelling of the jaw in one case. Thirty-four cases (87%) were associated with tooth eruption disturbances. The most frequently affected region was the maxillary anterior region. Treatment consisted of surgical removal of odontomas in all cases, after which if the impacted teeth did not erupt, exposure of the crown and/or orthodontic traction was performed. Pathological diagnoses were compound odontoma in 30 cases, complex odontoma (n = 7), and compound and complex odontoma (n = 2). A retrospective study of the radiographs revealed the developing process of odontomas in four cases and odontoma disturbed tooth eruption since the early uncalcified developing stage. A recurrent case was a boy aged 6 years 5 months in whom the first surgical removal of odontoma was performed at the age of 1 year 8 months. Recurrence of an odontoma is very rare, but in very young children odontomas are in the early developing stages, containing uncalcified portions, so it is important to perform periodical observations until the succedaneous teeth erupt.

Abstract
Delayed tooth eruption (DTE) is the emergence of a tooth into the oral cavity at a time that deviates significantly from norms established for different races, ethnicities, and sexes. This article reviews the local and systemic conditions under which DTE has been reported to occur. The terminology related to disturbances in tooth eruption is also reviewed and clarified. A diagnostic algorithm is proposed to aid the clinician in the diagnosis and treatment planning of DTE. The sequential and timely eruption of teeth is critical to the timing of treatment and the selection of an orthodontic treatment modality. This review addresses the need for a more in-depth understanding of the underlying pathophysiology of DTE and gives the clinician a methodology to approach its diagnosis and treatment.

Abstract
Multiple impacted teeth may be related to syndromes and metabolic disorders. In some cases, however, impaction of multiple teeth is not accompanied by a fixed complex of symptoms. A 55-year-old woman attended our clinic, as she was not comfortable with her prosthetic appliances because of erupted teeth. Panoramic and occlusal radiographs revealed 13 impacted teeth (12 permanent and 1 deciduous) in the maxilla and 15 impacted teeth (11 permanent and 4 deciduous) in the mandible. In total the patient had 28 impacted teeth. In our case, medical and family history and extraoral examination were not suggestive of any syndrome or metabolic disorder. In conclusion, radiographic examination may reveal multiple impactions in clinical absence of teeth. Lack of eruptive force and rotation of tooth buds may cause multiple impactions and additional examinations may be necessary to exclude systemic and metabolic conditions.
