An unusual presentation of calcifying odontogenic cyst with literature review.

The calcifying odontogenic cyst (COC) is an uncommon developmental odontogenic cyst, the oral counterpart of Malherbe's cutaneous calcifying epithelioma (pilomatricoma). This article presents two unique cases of calcifying odontogenic cysts each exhibiting distinctive histopathological features and its literature review. One case with an unexpected finding of cholesterol granuloma (CG), a rare occurrence in non-inflammatory cysts within an unusual location between two maxillary central incisors. One more instance involves the presence of a compound odontome in conjunction with COC. The cases underscore the clinical and histopathological diversity of COC and highlight the importance of radiological and histopathological assessments for accurate diagnosis. The unexpected association of COC with cholesterol granuloma challenges traditional diagnostic expectations. Additionally, the second case suggests that COCs may warrant sub-categorization to better understand their varied presentations and biological behavior. This article contributes to the expanding knowledge of COC, emphasizing the significance of documenting rare cases to enhance comprehension of its nature, pathogenesis, and oral cavity origin.

Diminutive compound odontoma in a child: a case report with emphasis on early detection.

The odontoma is regarded as a hamartomatous process of the jaws. Most are discovered as an incidental radiographic finding, averaging 15 mm in size. This report describes a case of a diminutive odontoma that was surgically removed before the onset of eruptive and pathologic consequences. A compilation of documented complications and syndromes associated with odontomas is also presented.

Compound Odontoma of the Anterior Maxilla Associated with Displaced Lateral Incisor: A Case Report.

INTRODUCTION: Odontomas are the most common odontogenic tumors worldwide and are usually chance findings seen on routine dental examinations. However, on progression, they may be associated with adjacent tooth displacement. CASE DESCRIPTION: We report a case of an 11-year-old girl who presented at the Lagos University Teaching Hospital (LUTH) pediatric dental clinic with a complaint of painless enlargement of the left anterior maxilla of 2-years duration. The swelling was located between teeth 21 and 22 and was associated with distal displacement and mesial angulation of tooth 22. Clinical, radiographic and histopathologic investigations revealed a compound odontoma. Surgical exposure and enucleation was done to remove the tumor. The patient's postoperative course and 6 months follow-up were uneventful. CONCLUSION: This report elucidates the importance of routine dental check-ups and minimally traumatic management of odontomas in pediatric dental patients to prevent adverse effects of odontomas, thereby, minimizing the interventions needed after surgical enucleation.

INTRODUCTION: Les odontomes sont les tumeurs odontogènes les plus courantes dans le monde et sont habituellement des découvertes fortuites observées lors des examens dentaires de routine. Cependant, lors de leur progression, ils peuvent être associés à un déplacement des dents adjacentes. DESCRIPTION DU CAS: Nous rapportons le cas d'une jeune fille de 11 ans qui s'est présentée à la clinique dentaire pédiatrique du Lagos University Teaching Hospital (LUTH) pour se plaindre d'un élargissement indolore du maxillaire antérieur gauche depuis deux ans. Le gonflement était situé entre les dents 21 et 22 et était associé à un déplacement distal et à une angulation mésiale de la dent 22. Les examens cliniques, radiographiques et histopathologiques ont révélé un odontome composé. Une exposition chirurgicale et une énucléation ont été effectuées pour retirer la tumeur. L'évolution postopératoire du patient et son suivi à 6 mois se sont déroulés sans incident. CONCLUSION: Ce rapport met en évidence l'importance des contrôles dentaires de routine et de la prise en charge des odontomes par des moyens peu traumatisants chez les patients pédiatriques afin de prévenir les effets indésirables des odontomes et de minimiser ainsi les interventions nécessaires après l'énucléation chirurgicale. Mots clés: Odontome composé, maxillaire antérieur, incisive latérale déplacée.

Delayed Eruption of Permanent Lower Lateral Incisor in Relation to Compound Odontoma: A Case Report.

AIM: To report a delayed tooth eruption following late surgical removal of a compound odontoma in a 10-year-old child. BACKGROUND: Odontomas are the most common odontogenic tumors. They are usually asymptomatic and discovered during routine radiographic examinations or during an assessment of delayed tooth eruption. Odontomas are classified into compound or complex based on the microscopic structure of dental tissues. Early diagnosis and surgical removal of odontomas is the keyword for favorable results. CASE DESCRIPTION: This paper describes a case of compound odontomas in a 10-year-old boy that prevented eruption of the permanent mandibular lateral incisor. Extraction of mandibular primary lateral incisors and surgical excision of the compound odontomas was performed. After 3 years of follow-up, at the age of 13 years, the permanent lateral incisor erupted and approached the occlusal plane. CONCLUSION: Late surgical removal of odontomas resulted in a delayed eruption of the affected teeth. CLINICAL SIGNIFICANCE: Surgical removal of odontomas and regular follow-up to monitor the eruption of the affected teeth should be considered for the teeth with an open apex before considering orthodontic traction.

Peripheral compound odontoma: A rare case report and literature review.

Peripheral odontoma is a very rare odontogenic hamartoma arising in soft tissues. Here, we report a case of peripheral odontoma in a pediatric patient and review the cases published in the literature. An 11-year-old male patient presented a nodular lesion in the anterior region of the palate for over 1 year. Under the clinical hypothesis of fibroma, an excisional biopsy was performed. Histopathological examination revealed the presence of tooth-like structures, formed by enamel, and dentin matrix, occasionally associated with the dental papilla and surrounding pulp tissue, thus, the histopathological diagnosis of peripheral odontoma was established. The patient has been undergoing follow-up for 6 months without any signs of lesion recurrence. Peripheral odontomas are uncommon lesions that usually affect young patients and display a preference for the maxilla and limited growth potential. The recognition of the clinical and histopathological features of the peripheral odontoma is indispensable for the establishment of its diagnosis.

Compound odontoma in a nine-years-old boy associated with impacted permanent central and lateral incisor - a case report.

Odontomas are one of the most common tumours of odontogenic origin. They are usually asymptomatic but may be associated with retained primary teeth or missing permanent teeth. Though the exact aetiology is unknown, the postulated causes include trauma, infection, inheritance and genetic mutation. Early diagnosis and management will result in fewer complications. Conservative surgical excision is the treatment of choice. This case report presents a treated case of compound odontoma associated with delayed eruption of the permanent central incisor in a nine-yearsold boy.

Compound Odontoma in Anterior Mandible-A Case Report.

Odontomas are the most common odontogenic hamartomas worldwide. Depending on the level of organisation of the tissues inside, these can be differentiated into compound type or complex type. As these are asymptomatic and do not cause any changes in the bone, they are often diagnosed during the routine dental examination. Complex odontomas are commonly found to occur in posterior mandible while compound odontomas are found in the anterior maxilla. A nine-year-old female child reported for a routine dental check-up, when a missing left permanent mandibular lateral incisor [32] was noticed. Further investigations revealed compound odontoma and unerupted 32, which is an unusual location. Early detection of these tumours is essential to avoid lengthy corrective treatments.

Clinical parameter of odontoma with special emphasis on treatment of impacted teeth-a retrospective multicentre study and literature review.

OBJECTIVES: Odontoma-separated into complex (CxOD) and compound (CpOD) subtypes-represents the most frequent odontogenic malformation. Retention of permanent teeth is a common symptom. Therefore, in a series of odontomas, an analysis of the management of retained teeth was conducted. MATERIALS AND METHODS: In a retrospective multicenter study of two University Medical Centers and one private praxis in Germany, demographic and clinical data regarding odontomas from 01/2000-03/2015 were obtained. In particular, the influence of operative therapy on the dentition and on the treatment of impacted teeth was analyzed. RESULTS: Forty-five patients with 15 CxOD and 30 CpOD were included. Initial symptoms were delayed eruption of permanent teeth (n = 11), pain (n = 4), and swellings (n = 2); 28 cases were discovered by incidence, all of them via panoramic radiographs. The mandible/maxilla ratio was about 1:0.55 (29/16). Thirty-five out of 45 odontomas were in close proximity of at least one tooth (n = 16 at molars). A total of 14 teeth were extracted (CxOD: n = 5; CpOD: n = 9). Extractions had to be conducted more often in older patients (mean age 39.8 vs. 25.6 years). Of the non-extracted teeth, 8 teeth were displaced and retained. Of those, 4 teeth were aligned in the dental arch via orthodontic help and 2 teeth erupted spontaneously after operation during the follow-up period. In all cases, no relapse was seen. CONCLUSION: Odontomas can cause displacement as well as malformation and resorption of the adjacent teeth. CLINICAL RELEVANCE: Mostly, removal of odontomas is conducted. Extirpation of odontoma can allow for normal tooth eruption, often rendering extractions avoidable. Orthodontic alignment, though sometimes challenging, is a reasonable therapeutic option. These findings underline the value of the panoramic radiograph in preventive dentistry in younger patients.

Extensive Maxillary Odontomas in 2 Dogs.

Two immature male dogs were presented for the treatment of extensive maxillary compound odontomas. In both cases, clinical evaluation and diagnostic imaging revealed extensive lesions invading and displacing anatomical structures of the maxilla. Histopathology confirmed the diagnoses in both cases. One dog was treated with partial rostral maxillectomy, and the other dog was treated with enucleation of the cystic lining and removal of tooth-like structures through a lateral rhinotomy utilizing an intraoral approach. This report illustrates the growth potential of maxillary compound odontomas in 2 dogs and highlights their subclinical appearance and excellent prognosis despite their extensive nature.

Surgical Management of Compound Odontoma in a Pediatric Patient: A Case Report.

Odontomas are the most common type of benign odontogenic tumors, representing around 70% of all odontogenic tumors of the jaws. Odontoma is typically present in the first and second decades of life. Morphologically, compound odontomas appear as deposited dental tissues in a pattern that makes a tooth-like structure. Compound odontomas can occur in any area of the jaws; however, the anterior maxilla is the most common location of compound odontomas. In the current report, we aimed to remove the tumor surgically to avoid unwanted consequences of odontomas, such as eruption disturbance, root resorption, tooth malalignment, and cortical bone expansion.  An 11-year-old female patient presented to the pediatric dental clinic in Security Forces Hospital, Makkah, Saudi Arabia, complaining of multiple carious teeth. A routine panoramic radiograph showed a well-defined radiopaque mass surrounded by a thin halo in the right maxillary anterior region. This mass comprised multiple small, tooth-like structures. Upon pulpation, a palatal bulge was detected on the right side of the anterior part of maxilla. Since the patient showed anxious dental behavior and needed comprehensive dental treatment, she was scheduled for surgical removal of the mass under general anesthesia. Tiny tooth-like structures were removed and sent to the histopathological examination to confirm the diagnosis. Follow-up appointments for the patients were scheduled to be after two weeks, one month, and six months. In conclusion, this case highlights the importance of early diagnosis and prompt surgical intervention in managing compound odontomas to avoid the unwanted consequences of the tumor.

The Enigma Unveiled: Expansile Compound-complex Odontoma in the Anterior Maxilla of a Teenager.

Aim and objective: The objective of this case report is to offer insight into an expansive compound-complex odontoma located in the anterior maxilla of a 15-year-old male. The focus is placed on the importance of early detection and the progressive comprehension of odontomas. Background: Odontomas are common odontogenic lesions that are frequently discovered during examinations for delayed tooth eruption. There are two distinct classifications for odontomas-compound odontomas and complex odontomas. With its own each set of characteristics. A timely diagnosis is critical for avoiding complications. Case description: A male individual aged 15 years exhibited an expansive compound-complex odontoma located in the anterior maxilla. The clinical examination showed delayed tooth eruption and asymptomatic swelling. The radiographic images showed a radiopaque mass with tooth-like structures and radiolucent borders affecting the surrounding dentition. A surgical excision procedure was conducted, followed by a subsequent histopathological examination confirming the diagnosis of compound-complex odontoma. The patient continued orthodontic treatment after a 1-year follow-up without recurrence. Clinical significance: This case emphasizes the importance of regular dental exams in detecting odontomas early. This observation also highlights the growing understanding of odontomas as hamartomatous odontogenic malformations and the challenges of diagnosing them clinically. Additional molecular investigations are required to facilitate the classification and elucidation of genetic factors. How to cite this article: Alhazmi YA.

A Fortuitous Finding of Asymptomatic Compound Odontoma Consisting of 156 Denticles on a Routine Radiographic Examination: A Case Report.

Odontomas are the most common odontogenic tumors and are classified into compound and complex types. They result from a combination of odontogenic epithelium and ectomesenchyme. Complex odontomas frequently occur in the posterior mandible, whereas compound odontomas are more commonly found in the anterior region of the maxilla. Due to their small size and asymptomatic nature, odontomas are often diagnosed incidentally. Typically, odontomas are <3 cm in diameter; those exceeding this size are classified as giant odontomas and may present with extraoral swelling. This case report documents an unusual instance of a giant compound odontoma, containing 156 denticles, in a 15-year-old girl. Despite the odontoma's large size in the mandibular anterior region-an uncommon site for compound odontomas-the patient was completely asymptomatic and presented with only intermittent pain in the lower right back tooth region over the past month. The denticles were extracted, and intentional root canal treatment was performed on teeth 41, 42, 31, and 32 under general anesthesia. How to cite this article: Chiranjeevi S, Prabhuraj SN.

Rare Variant of a Giant Compound Odontoma of the Maxilla: A Case Report.

Benign odontogenic tumors that produce features resembling teeth are known as compound odontomas. This case report describes a unique case of a compound odontoma presenting in the patient's maxillary, the front region. This example highlights how crucial it is to diagnose and treat odontomas as soon as possible in order to avoid possible consequences like tooth displacement or failed eruption. It also emphasizes how important imaging methods are to accurately localizing and planning surgery for odontogenic tumors. The effective handling of this case offers important insights into the multidisciplinary approach needed for odontoma patient diagnosis, treatment, and follow-up.

Gigantic Multiple Odontomas of Jaws in a Pediatric Patient: A Rare Case.

Odontomas are mixed epithelial and mesenchymal tumor-like malformations (hamartoma) composed of dental hard and soft tissue, causing delayed teeth eruption. Multiple case reports have been published in the literature describing solitary, localized odontoma features in pediatric patients along with their treatment planning. This report presents clinical and radiographic features of gigantic multiple odontomas involving both jaws in a five-year-old boy.

Radiographic characteristics of odontomas in patients in the National Taiwan University Children's Hospital.

Background/purpose: Odontoma is the most common odontogenic tumor. A literature review revealed limited data for odontomas in Taiwan. This study evaluated the radiographic characteristics of odontomas in 1280 patients in the National Taiwan University Children's Hospital (NTUCH). Materials and methods: This retrospective study analyzed the odontomas based on examination of mainly panoramic radiographs and related radiographs of 1280 patients in the NTUCH. Chi-square test was used for trend analysis. Results: Among 1280 patients (710 boys and 570 girls), a total of 16 patients with odontomas (10 boys and 6 girls) were identified. There were 14 compound and 2 complex odontomas. The mean age of the patients was 10.38 years with the majority of odontomas occurring in the first (37.5%) and second decade (62.5%) of life. Odontomas had a marked predilection for the mandible (56.25%) and for the anterior region of the jaws (75%), particularly for the anterior maxilla (43.75%). Ten odontomas (62.5%) were associated with the impacted corresponding permanent teeth. The sagittal position of odontomas and vertical relation of odontomas to the corresponding permanent teeth were significantly correlated with the eruption rate of corresponding permanent teeth (P < 0.05). Conclusion: The odontomas occur most commonly in male patients with a male to female ratio of 1.67:1. The incidence of odontomas in our 1280 patients is 1.25%. The age range of patients with odontomas is 6-17 years. The most frequent location of odontomas is the anterior maxillary region. Odontoma is frequently associated with an impacted corresponding permanent tooth.

A spontaneous compound odontoma in an adult Sprague Dawley rat (Rattus norvegicus).

Reports of compound odontomas in rats are very rare. A 14-month-old adult male Sprague Dawley rat was found to have a hard mass associated with the caudal aspect of the left mandible. After 2 weeks of observation, the rat was euthanized due to the mass growing significantly in size and the rat losing >20% of its body weight. Grossly, the mass was well-circumscribed, 3.7 × 3 × 1.2 cm, hard and heterogeneously coloured white, tan and red. The mass was restricted to the mandibular bone and did not involve surrounding subcutaneous tissue. On cut surface, the mass was a similar colour and brittle. Histologically, there were numerous proto-teeth embedded in ossified stroma. Each proto-tooth had a central mesenchyme pulp surrounded by columnar odontoblasts and dentine matrix. The dentine was often bordered by enamel matrix, which was occasionally bounded by ameloblasts. These histological findings were consistent with a compound odontoma. This is the first report of a spontaneous compound odontoma in the caudal mandible of a rat.

Clinicoradiopathologic Analysis of Odontomas: A Retrospective Study of 242 Cases.

Odontomas are considered hamartomatous lesions and are one of the two most common odontogenic tumors of the jaw. Odontomas are classified as compound or complex. Recently, ameloblastic fibro-odontoma (AFO) and ameloblastic fibro-dentinoma were reclassified as developing odontomas. Though clinically odontomas are usually asymptomatic, they have adverse effects on adjacent teeth such as tooth impaction, delayed eruption, displacement of teeth, over-retention of teeth, and can give rise to odontogenic cysts within the jaw. We sought to evaluate the clinicoradiopathologic presentations of odontomas by collecting and analyzing the clinical, radiographic, and pathologic data of odontomas diagnosed in our institution from 2013 to 2022. Over this 10-year period, there were 242 patients with a histopathological and/or radiographic diagnosis of odontoma. There was no gender predilection and ages ranged from 3 to 101 years (median, 14 years). The second decade of life was the most prevalent (57.4%). There was no jaw predilection; however, the anterior jaw was the most common location. Ninety-four (38.8%) cases presented with clinical findings. The most common finding was tooth impaction (n = 83). Nine (3.7%) cases were histopathologically confirmed to be associated with other lesions such as dentigerous cysts (n = 8) and nasopalatine duct cyst (n = 1). The median age (25 years) of patients diagnosed with odontomas associated with cysts was older than patients with odontomas (14 years) without associated cysts. Compound odontomas were the most common type of odontoma compared to complex and AFOs with 71.4%, 26.6%, and 2%, respectively. The majority of compound odontomas involved the anterior jaw (69.3%) and mandible (54.9%) while the majority of complex odontomas involved the posterior jaw (59.6%) and maxilla (54.7%). The four AFOs were in the posterior jaw and 75% involved the maxilla. The median age (12 years) of patients diagnosed with AFO was the youngest compared to patients diagnosed with compound (13 years) and complex (16 years). In conclusion, we analyzed the clinical, radiographic, and pathologic features of 242 new cases of odontomas. Our study reaffirms that odontomas frequently affect the pediatric population and can disrupt their dentition. Based on the result of this study, our clinical recommendation to prevent problems to adjacent teeth from odontomas is for dentists to be apt in the diagnose of odontomas to ensure that they are surgically removed in a timely manner.

Compound Odontoma and Dentigerous Cyst Associated With an Unerupted Maxillary Canine Tooth in a Weimaraner Dog: A Case Report.

A 7-month-old, male, Weimaraner dog was presented for maxillary swelling. Clinical evaluation including radiographs and computed tomography revealed a large cystic lesion, unerupted right maxillary canine tooth, and mass presumed to be a compound odontoma. The cyst and mass were expansile and occupied a large portion of the nasal cavity displacing anatomical structures of the maxilla. The mass was excised via curettage through an intraoral surgical approach and the unerupted tooth and cystic lining were removed. Histopathology supported dentigerous cyst and compound odontoma. This case confirms the first report of concurrent development of dentigerous cyst and compound odontoma in a dog with successful treatment and 18-month follow-up with no recurrence.

Calcifying odontogenic cyst associated with compound odontoma - A rare entity.

Calcifying odontogenic cyst (COC) or Gorlin's cyst categorized as a distinct entity by Gorlin et al. in 1962. It is a rare benign developmental cystic lesion that accounts for less than 1% of all odontogenic cysts. It can occur in association with various types of odontogenic tumors such as odontomas. COC is a hybrid lesion of the jaw presenting a manifold variety of clinical behaviors and histopathological characteristics including cystic, solid (neoplastic), and aggressive forms. COC exhibits diversity in terms of its clinical presentations, histopathologic features, and biological behavior. Normally, it presents as asymptomatic, slow developing lesion affecting the maxilla and mandible equally with strong predilection for the anterior segment. Radiographically, these lesions usually present as a unilocular, well-defined radiolucency with radiopaque structures within the lesion, either as irregular calcifications or tooth-like densities. The distinct features of COC as solid or cystic lesions presents with an ameloblastomous component admixed with varying proportions of ghost cells and spherical calcifications. Here, we report an article of calcifying odontogenic cyst associated with compound odontoma in a young patient with lesion in the anterior mandible with review of the various terminologies and classification and histopathology.

Management of Mandibular Compound Odontoma With Numbness in the Lower Jaw.

Odontomas are considered to be among the more common odontogenic tumors in the oral cavity. Several authors classify them as hamartomas instead of actual tumors. Odontomes' precise etiology is still unknown. The majority of odontomas are found during routine radiography studies and are asymptomatic. Odontomes typically cause disruptions to the teeth's eruption, most frequently deflection or delayed eruption. Here, the reported study details the surgical management of a mandibular compound odontoma in a patient who presented with a complaint of numbness in his lower jaw.
