[PMID: 39035564 PMCID: PMC11255926 DOI: 10.1016/j.sdentj.2024.05.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Revised: 05/08/2024] [Accepted: 05/09/2024] [Indexed: 07/23/2024] Open
Abstract
Objective Benign fibroosseous lesions (BFOLs) encompass a heterogenous collection of bone conditions characterized by replacing normal bone with fibro-collagenous tissue with osteoid or woven bone, and cementicles. Despite their clinical significance, the frequency of BFOLs in Saudi Arabia still needs to be assessed. Methods This retrospective study investigated the frequency and demographics of BFOLs in Riyadh, Saudi Arabia, by retrieving all cases recorded between January 1984 and January 2013 from a single Oral Pathology Laboratory archive. Results A total of 64 cases were classified as BFOLs, with a predominance in females (67.2 %) and a median age of 21.5 years. The most prevalent condition identified was fibrous dysplasia (45.31 %), followed by cemento-ossifying fibroma (26.56 %). There were significant sex differences between BFOLs, with a p-value of 0.03. FD was predominantly located in the maxilla (65.5 %), whereas COF was predominantly found in the mandible (82.3 %). Recurrence was observed in 17.2 % of patients with FD, in contrast to no reported recurrence in patients with COF. Conclusion This study represents the first exploration of BFOL frequency and demographics in Riyadh, Saudi Arabia, highlighting the need for further investigations to comprehensively understand the nature of these lesions in our population.

Abstract
BACKGROUND Familial gigantiform cementoma (FGC) is a rare tumor characterized by the early onset of multi-quadrant fibro-osseous lesions in the jaws, causing severe maxillofacial deformities. Its clinicopathological features overlap with those of other benign fibro-osseous lesions. FGC eventually exhibits progressively rapid growth, but no suspected causative gene has been identified. METHODS In this study, three patients with FGC were recruited, and genomic DNA from the tumor tissue and peripheral blood was extracted for whole-exome sequencing. RESULTS Results showed that all three patients harbored the heterozygous mutation c.1067G > A (p.Cys356Tyr) in the ANO5 gene. Furthermore, autosomal dominant mutations in ANO5 at this locus have been identified in patients with gnathodiaphyseal dysplasia (GDD) and are considered a potential causative agent, suggesting a genetic association between FGC and GDD. In addition, multifocal fibrous bone lesions with similar clinical presentations were detected, including five cases of florid cemento-osseous dysplasia, five cases of polyostotic fibrous dysplasia, and eight cases of juvenile ossifying fibromas; however, none of them harbored mutations in the ANO5 gene. CONCLUSION Our findings indicate that FGC may be an atypical variant of GDD, providing evidence for the feasibility of ANO5 gene testing as an auxiliary diagnostic method for complex cases with multiple quadrants.

Abstract
Background Familial gigantiform cementoma (FGC) is a rare benign fibrocemento-osseous lesion of the jaw characterized by well-circumscribed, extensive, mixed radiolucent-radiopaque masses in the mandible and the maxilla that can cause severe facial deformity. This condition is extremely rare with less than 40 cases reported in the literature. Purpose The purpose of the paper is to highlight the importance of virtual surgical planning and patient-specific implant in the treatment of a complex lesion and reconstruction of the facial skeleton. The clinical presentations, and diagnostic challenges encountered when managing the lesion have been discussed in this article with emphasis on the treatment plan. Method/Surgical plan The sequence of treatment planned was resection of the lesion and immediate reconstruction with a patient-specific implant to improve the patient's quality of life. The management of FGC was a challenging one keeping in mind the rapid expansion of the lesion, widespread involvement of the jaws, and needs of the pediatric patient. Conclusion Virtual surgical planning (VSP) along with 3D printed implant was instrumental in reconstructing the facial form of the child where the maxilla was completely resected and rehabilitation provided support to the vital structures of the face.

Abstract
ANO5 encodes transmembrane protein 16E (TMEM16E), an intracellular calcium-activated chloride channel in the endoplasmic reticulum. Mutations in ANO5 are associated with gnathodiaphyseal dysplasia (GDD), a skeletal disorder causing the jaw deformity and long bone fractures. However, the coordinated mechanism by which ANO5 mediates bone homeostasis in GDD remains poorly defined. Here, we show that ablation of Ano5 reduced intracellular calcium transients, leading to defects in osteogenesis and osteoclastogenesis and thus bone dysplasia. We found a causative de novo ANO5 frameshift insertion mutation (p.L370_A371insDYWRLNSTCL) in a GDD family with osteopenia, accompanied by a decrease in TMEM16E expression and impaired RANKL-induced intracellular calcium ([Ca2+]i) oscillations in osteoclasts. Moreover, using Ano5 knockout (KO) mice, we found that they exhibited low bone volume, abnormal calcium deposits, and defective osteoblast and osteoclast differentiation. We also showed that Ano5 deletion in mice significantly diminished [Ca2+]i oscillations in both osteoblasts and osteoclasts, which resulted in reduced WNT/β-Catenin and RANKL-NFATc1 signaling, respectively. Osteoanabolic treatment of parathyroid hormone was effective in enhancing bone strength in Ano5 KO mice. Consequently, these data demonstrate that Ano5 positively modulates bone homeostasis via calcium signaling in GDD.

Abstract
Background Familial gigantiform cementoma is an autosomal dominant fibro-cement osseous lesion that causes massive expansion of facial skeleton. Patients with such massive lesions have a compromised quality of life. The main goal of treating such patients is to restore and preserve the jaw as far as possible which would enhance their quality of life. Purpose This study was conducted to identify the occurrence of gigantiform cementoma which had affected three generations of a family and also to focus on documentation of the clinical course and management. Method Patients (one family-mother, grandmother, aunt and grandson) who had visited the Department of Oral and Maxillofacial Surgery, Tamilnadu Government Dental College and Hospital, Chennai, over a period for their swelling in the maxillofacial region were clinically and radiographically evaluated and histopathologically diagnosed as familial gigantiform cementoma; later, they were surgically managed. Result It is very rare to document three generations of this disease which had shown varied clinical presentation (asymptomatic slow growth, arrested growth and one case of aggressive growth). Management of these cases varied from observation to aggressive resection. Conclusion Gigantiform cementoma follows an autosomal dominant pattern of inheritance with variable phenotypic expression without gender predilection. These cases require regular observation and intervention if necessary.

Abstract
Familial gigantiform cementoma (FGC) is a rare benign fibro-cementum lesion, which follows an autosomal dominant inheritance pattern and presents during childhood. It is limited to the bones of the face, with a predilection for the jaw, is fast growing and painless and expands considerably over time. It is considered among the seven disorders that affect the physiognomy of the craniofacial skeleton. Radiographically, FGC occurs in three stages of maturation similar to bone dysplasia, being radiolucent, mixed and radiopaque and is described as a mixed lobular well delimited mass, which can occur in both maxillae, causing expansion of the buccal and palatal / lingual bone cortices. displacement and retention of teeth. The aim of this study was to perform a review of the literature to identify the clinical, radiographic and histopathological characteristics of FGC in the jaws and describe the imaging tools that are useful for the diagnosis and follow-up of this lesion.

Abstract
Familial cases of benign fibro-osseous lesions of the jaws are rare and have been described under numerous terms including familial gigantiform cementoma, multiple cemento-ossifying fibromas, sclerotic cemental masses and familial florid cemento-osseous dysplasia. The synonymous and interchangeable use of these terms to describe distinct entities with overlapping features has resulted in confusion and inaccurate categorisation of these lesions. This study highlights three family members with diffuse fibro-osseous jaw lesions with areas of significant expansion. In the pursuit of finding the best clinicopathological categorisation for the reported cases, familial florid cemento-osseous dysplasia and familial gigantiform cementoma were investigated. The final consensus of these three cases was that of familial florid cemento-osseous dysplasia, and one patient presented with a concurrent "ossifying fibromatoid lesion". A literature review on the above entities was performed in an attempt to provide clarification and delineate distinguishing features of the individual diseases.
