OBJECTIVE
This review aimed to summarize recent progress on syndromic dentin defects, promoting a better understanding of systemic diseases with dentin malformations, the molecules involved, and related mechanisms.
SUBJECTS AND METHODS
References on genetic diseases with dentin malformations were obtained from various sources, including PubMed, OMIM, NCBI, and other websites. The clinical phenotypes and genetic backgrounds of these diseases were then summarized, analyzed, and compared.
RESULTS
Over 10 systemic diseases, including osteogenesis imperfecta, hypophosphatemic rickets, vitamin D-dependent rickets, familial tumoral calcinosis, Ehlers-Danlos syndrome, Schimke immuno-osseous dysplasia, hypophosphatasia, Elsahy-Waters syndrome, Singleton-Merten syndrome, odontochondrodysplasia, and microcephalic osteodysplastic primordial dwarfism type II were examined. Most of these are bone disorders, and their pathogenic genes may regulate both dentin and bone development, involving extracellular matrix, cell differentiation, and metabolism of calcium, phosphorus, and vitamin D. The phenotypes of these syndromic dentin defects various with the involved genes, part of them are similar to dentinogenesis imperfecta or dentin dysplasia, while others only present one or two types of dentin abnormalities such as discoloration, irregular enlarged or obliterated pulp and canal, or root malformation.
CONCLUSION
Some specific dentin defects associated with systemic diseases may serve as important phenotypes for dentists to diagnose. Furthermore, mechanistic studies on syndromic dentin defects may provide valuable insights into isolated dentin defects and general dentin development or mineralization.

Review
Evaluation of bone pathology within the head and neck region, particularly the gnathic bonesis is complex, demonstrating unique pathologic processes. In part, this variation is due to odontogenesis and the embryological cells that may be involved, which can contribute to disease development and histologic variability. As with any boney pathosis, the key is to have clinical correlation, particularly with radiographic imaging prior to establishing a definitive diagnosis. This review will cover those entities that have a predilection for the pediatric population, and while it is not all inclusive, it should serve as a foundation for the pathologist who is evaluating bony lesions involving the craniofacial skeleton.

Review
Regional odontodysplasia (ROD) is a rare localized dental developmental anomaly. The typical clinical manifestations of ROD are abnormal tooth eruption, abnormal development of enamel and dentin. The radiographic characteristic is "ghost teeth". Its etiology still remains unknown. The care and treatment of a patient with ROD needs a multidisciplinary approach. And the treatment should be taken after the assessment of each individual case of ROD. This paper reviews the definition, etiology, epidemiological features, clinical manifestations, imaging features, dental microstructure and treatment strategies of ROD to provide reference for clinical diagnosis and treatment.

Review
Unique dental conditions in children include odontogenic cysts and tumors, hereditary dental diseases, developmental anomalies, and lesions associated with the eruption of the primary or permanent teeth. Many of these conditions have long lasting effects on the adult dentition in terms of affecting esthetics, function, and overall quality of life. Inherited dental syndromes affect the dental hard tissues specifically the enamel, dentin, and/or cementum in a generalized manner, involving both primary and permanent teeth. These conditions manifest in altered quality or quantity of the hard tissues, leading to fragility, tooth loss and dental diseases such as caries, periapical pathology, and periodontal disease. This category includes amelogenesis imperfecta, dentinogenesis imperfecta, dentin dysplasia, hypophosphatasia, and hypophosphatemia. Developmental defects such as regional odontodysplasia are defined by involvement of the primary and permanent dentition in a localized manner, identified in early childhood. This review will elaborate on the histologic findings in these selected dental conditions with a discussion on clinical and radiographic findings, as well as molecular features wherever appropriate.

PHACES syndrome is an acronym for the syndromic presentation of Posterior fossa malformation, Hemangioma, Arterial anomalies, Coarctation of aorta/cardiac defects, Eye abnormalities and Sternal malformations. Infantile hemangiomas are the most common tumors of infancy. Regional odontodysplasia, commonly referred to as "ghost teeth", is a rare localized developmental malformation of enamel and dentin with varying levels of severity that results in unusual clinical and radiographic appearances of affected teeth. This report describes a rare case of a two-year-old Caucasian male diagnosed with PHACES syndrome also presenting with multi-regional odontodysplasia. Ten of twenty teeth were dysplastic. The patient was treated under general anesthesia in a hospital setting. All affected primary teeth were extracted due to sensitivity, abscess and extremely poor long-term prognosis. Moving forward, a long-term interdisciplinary approach will be necessary to address this child's dentition as it develops.

Review
Regional odontodysplasia (ROD) is a localized developmental anomaly involving deciduous and permanent dentition, with a significant impact on patients. The affected teeth display unique ghost-like radiological characteristics, clinically manifesting as delayed tooth eruption, abnormal tooth morphology, and recurrent swelling of gingiva. In this paper, we report a case of a 2-year-old patient with ROD whose chief complaint was facial cellulitis. We analyze the medical history, clinical examination, radiographic findings, and histologic findings, and review the pathological features, pathogenesis, multidisciplinary diagnosis, and treatment of ROD. This rare case, which offers clinical samples for its further study, can provide a deeper study of ROD.

Regional odontodysplasia (RO) is a rare non-hereditary dental anomaly associated with dysplasia. Its etiology remains unclear but is known to affect both the mesodermal and ectodermal dental components, as well as deciduous and permanent dentitions. Its young age of onset and complexity has great physical and psychological impact on the affected patients. However, the clinical management of RO remains unified without standardized treatment guidelines. Thus, this study aimed to report an RO case, the first from Jiangxi Province, China, and discuss its clinical diagnosis and treatment to provide a reference to treat similar cases more effectively in the future.

Segmental odontomaxillary dysplasia (SOD) is an uncommon and likely underrecognized developmental condition. In rare cases, SOD can also result in anomalies of the ipsilateral mandibular alveolar process and teeth. This report presents two cases of SOD with mandibular involvement to highlight this potential variation in SOD presentation. These cases help shed new light on our understanding of the disease mechanism and pathoetiology, while also informing clinicians to be diligent in imaging the ipsilateral mandible for dental anomalies in their patients with SOD. Based on the involvement of both jaws, the name change to 'segmental ipsilateral odontognathic dysplasia' is justified to better reflect its pathophysiology.

Review
Segmental odontomaxillary dysplasia (SOD) is a rare and unusual nonhereditary developmental disorder that affects one side of the maxilla, impacting the hard tissue, soft tissue, and dentition in the affected area. It most frequently presents with enlargement of the gingival and osseous tissue of the affected side and hypodontia of the involved quadrant. Cutaneous irregularities of the impacted area are also common. We report a case of SOD arising in the right maxilla of a three-year-old female. Our report and review of the literature highlight the clinical, radiographic, and histopathologic characteristics of SOD, as well as the management of patients and the proposed etiologies of its pathogenesis.

Regional odontodysplasia (RO) is a rare developmental abnormality of epithelial and mesenchymal dental tissues. Due to its poorly understood etiology, assessing and discussing related clinical cases of this dental anomaly is crucial to guide professionals in improving its treatment and outcomes. This article aimed to report the case of a 9-year-old male patient who presented to our department with the main complaint of absent eruption of permanent left mandibular quadrant teeth. This is the first case reported in China from a patient with multiple cutaneous nevi on the face and neck, and based on the retrieved clinical and radiographic features, we described and discussed the treatment and etiology of RO.
