Abstract:
Comparative study of bone and lamellar bone formation in Peripheral Giant Cell Granuloma and Peripheral Ossifying Fibroma Dr. SH. Ghasemi Moridani* - Dr. H. Mahmoodi Chenari* *-Assistant Professor of Oral and Maxillofacial Pathology Dept.-Faculty of Dentistry-Guilan University of Medical Sciences. **- Dentist. Background and Aim: Peripheral Giant Cell Granuloma (PGCG) and peripheral ossifying fibroma (POF) are reactive gingival lesions producing bony tissue. This bony tissue can be woven or lamellar. The aim of this study was to compare the percent of bone and lamellar bone formation in PGCG and POF. Materials and Methods: Twenty – five cases of PGCG and twenty – five cases of POG were selected from the files of Oral pathology department of Tehran Faculty of Dentistry and Razi Pathobiology laboratory of Rasht. Clinical data including age, gender and location of lesion were recorder. The percent of bone and lamellar bone formation were determined using light microscope and polarized light. In order to compare the percentage of bone formation in lesions t – test was used and Pearson correlation coefficient was used to investigate the relationship between the mentioned variables and age. Results: The percent of bone and lamellar bone formation in PGCG were 9.06% and 45.05%, respectively and in POF were 8.72% and 35.18%, respectively showing no statistically significant difference in these two lesions. There was no relationship between the percent of bone formation and age, gender and also location of lesion in each of them. Mean volume of PGCG and POF lesions were 3.18cm3 and 1.34cm3, respectively. Conclusion: There was no statistically significant difference in the percent of bone formation between PGCG and POF. However, considering the difference between volumes it appears that bone formation may be greater in POF. Key words: Peripheral ossifying fibroma – Peripheral Giant Cell Granuloma – Bone formation - Lamellar bone

OBJECTIVES The aim of this study was to present the clinical and histopathological evaluation of reactive gingival lesions, such as peripheral giant cell granuloma (PGCG) and peripheral ossifying fibroma (POF), as exemplified in two cases. CLINICAL PRESENTATION AND INTERVENTION A 12- and a 13-year-old girl were referred to the Department of Pedodontics, both complaining of a painless swelling...

Introduction: Despite similar histopathological features, peripheral giant cell granuloma (PGCG) and central giant cell granuloma (CGCG) differ in their biological behavior. PGCG and CGCG are hemorrhagic/vascular lesions, clinically and microscopically. Angiogenesis is necessary for the growth and development of lesions and affects their clinical behavior. CD105 is a useful vascular marker for...

INTRODUCTION Peripheral giant cell granuloma and peripheral ossifying fibroma are clinicopathologically distinct gingival lesions. Both are included in clinical differential diagnoses of common benign and reactive gingival epulides in humans. It is often impossible to make a clinical distinction between the two entities, thereby making definitive diagnosis dependent on histopathologic features....

Peripheral ossifying fibroma (POF) is a common solitary gingival growth thought to arise from the periodontal ligament. Though the etiology of POF remains unknown, some investigators consider it an inflammatory or reactive process, while others suggest it is a neoplastic process. In this report, we present and discuss a unique case of multicentric POF, affecting the maxillary and mandibular gin...

Peripheral ossifying fibroma
A case of peripheral ossifying fibroma (POF) in the mandibular gingiva of a 17-year-old male is described. The lesion was asymptomatic, firm, pink, and present on the lingual alveolar mucosa interdentally between 43 and 44. Radiographic investigations revealed no significant findings. Excisional biopsy was performed for the lesion. Microscopic findings confirmed the diagnosis of POF.
