Minimally Invasive Decompression And Long-Term Follow-Up Of An Orthokeratinized Odontogenic Cyst Of The Mandible: A 7-Year Case Report, Akram Belmehdi, Karima El Harti

International Arab Journal of Dentistry

Introduction: Orthokeratinized odontogenic cyst (OOC) is a rare developmental jaw lesion with indolent behavior and low recurrence potential.

Case presentation: A 33-year-old healthy male was referred after incidental discovery of a mandibular radiolucency. Cone-beam CT revealed a well-defined unilocular lesion in close relation to the inferior alveolar canal. Aspiration confirmed its cystic nature, and a conservative decompression was performed using a rubber drain to reduce lesion size and preserve adjacent structures. Histopathologic examination identified orthokeratinized epithelium consistent with OOC. After seven months of decompression, the lesion showed marked ossification, allowing safe enucleation and peripheral curettage. Radiographic follow-ups at 19 months …

A Comprehensive Analysis Of The Accurate Diagnosis Of Chronic Non-Bacterial Osteomyelitis Of The Jaw In Young Patients: An Assessment Of Clinical And Laboratory Data, Alexander Yu Kugushev, Andrey V. Lopatin, Suzan Dagher

International Arab Journal of Dentistry

Objectives: Chronic non-bacterial osteomyelitis (CNO) is a rare autoinflammatory bone disorder predominantly affecting pediatric and adolescent populations. The clinical presentation is heterogeneous, with persistent pain and swelling representing the most frequent and often initial symptoms. These manifestations are commonly localized to the mandible, although involvement of other skeletal sites, including long bones, clavicle, and vertebrae, may occur in more advanced cases. Beyond localized symptoms, some patients exhibit mild systemic features such as low-grade fever, fatigue, or malaise; however, these systemic signs are generally less pronounced than those observed in infectious osteomyelitis. The diagnostic evaluation of CNO is intricate and necessitates …

Management Of A Periapical Cyst In An 8-Year-Old Patient With Challenging Etiology: A Case Report With Three-Year Follow-Up, Nancy Nochahrly, Claire El Hachem, Josephine El Balaa, Elie Khoury, Christelle Abdel Nour, Marlene Khoury

International Arab Journal of Dentistry

The success of pulp therapy in primary teeth depends on accurate diagnosis and effective treatment. Periapical inflammation due to bacterial infection or pulpal necrosis can result in granulation tissue and may activate epithelial rests of Malassez, leading to a periapical cyst. In large cysts, especially in children, marsupialization is preferred to preserve developing teeth and minimize damage to surrounding structures. This case report describes an 8-year-old presenting with spontaneous pain in the lower right jaw. Radiographic examination revealed a round welldefined radiolucency over 1 cm around tooth #84 with root canal treatment and #85 with pulpotomy, with dental bud displacement. …
