Juvenile Ossifying Fibroma (JOF) is a type of ossifying fibroma which occurs in younger individuals and manifests as trabecular and psammomatoid variants. The nature and behaviour of these variants vary, and they exhibit characteristic histopathological appearance. The solitary presentation of these subtypes is reported in numbers, but co-occurrence of both these entities is very few. Here, we present a case of JOF with the co-occurrence of both trabecular and psammomatoid variants in relation to an incompletely healed extraction socket.

Peripheral ossifying fibroma (POF) is a reactive overgrowth that most commonly occurs on the gingiva. It is a benign oral soft tissue tumour. It is most commonly found on the anterior maxilla and has a female predilection. Most commonly found to occur in the second decade of life. This type of lesion originates from the cells of the periodontal ligament. It is often associated with trauma or local irritants, such as subgingival plaque and calculus, dental appliances and poor-quality dental restorations. This entity requires a proper treatment protocol and a regular follow-up. It can cause significant discomfort and irritation in the oral health if left untreated. The recurrence rate of the lesion varies according to the authors. This case report describes a case of POF in an adult female patient which was treated using surgical excision resulting in an uneventful healing during the post-operative period.

Review
BACKGROUND
Odontogenic tumours are infrequent lesions. Studies on the frequency of odontogenic tumours from Latin America are scarce. This work aimed to determine the relative frequency of odontogenic tumours in a Chilean population using the 2022 World Health Organization classification.
MATERIAL AND METHODS
This is a case series retrospective study. We reviewed 35,530 samples from 1975 to 2022 from the Oral Pathology Referral Institute and the Pathological Anatomy Service, Faculty of Dentistry, University of Chile. We utilized the 2022 World Health Organization classification for histological typification.
RESULTS
According to 2022 World Health Organization classification, 544 odontogenic tumours were confirmed. The most frequent odontogenic tumours were: odontoma (n=241; 44.3%), ameloblastoma (n=109; 20.0%) and cemento-ossifying fibroma (n=71; 13.1%). Benign odontogenic tumours corresponded to 538 cases (98.9%) and malignant tumours were only six cases (1.1%).
CONCLUSIONS
In our population, odontoma was the most frequent odontogenic tumour followed by ameloblastoma and cemento-ossifying fibroma. Malignant odontogenic tumours were very rare. The results of this study are similar to reports from America, but there are some differences concerning the data from Africa and Asia.

INTRODUCTION
Ossifying fibromas are rare, non-aggressive benign tumours of the bone, commonly involving the posterior mandible in middle-aged individuals with a female predilection.
FINDINGS
Clinical manifestations include asymptomatic expansion of the mandible with infrequent maxillary lesions, pain, malocclusion, and compromised quality of life including aesthetic perception. Owing to multiplicity of features, tendency of recurrence, and possibility of malignant transformation, the diagnosis, treatment, and post-operative management of ossifying fibroma are always a challenge.
TAKEAWAY LESSONS
Study aims to report a clinical case of extensive swelling involving the coronoid process and condyle on the right side to crossing the mid-line of the mandible with compromised functions and aesthetics. The article describes the clinical, histopathological, and radiological features of the case. The possible treatment and challenges encountered are discussed.

UNLABELLED
A significant percentage of lesions of endodontic origin require surgical management due to the possible diagnosis of odontogenic cysts and tumors in the maxilla and mandible. Ossifying fibroma is a benign fibro-osseous lesion that typically presents as a painless, slow-growing, and expansile lesion that appears as a well-demarcated lesion with a variable degree of internal calcification on radiography. Treatment results in a large osseous defect, utilization of a graft to fill the void accelerates healing and prevents complications that may result from failure to fill by the host response.
CASE PRESENTATION
Following endodontic surgery placement of osseous graft material via Guided Tissue Regeneration to fill the defect aids to accelerate fill of the defect on a healthy 26-year-old female patient. A case discussing the one-step treatment of an ossifying fibroma of the anterior part of the mandible following endodontic microsurgery with associated retrograde fill of the apex, then site grating with biphasic calcium sulfate (Bond Apatite) used in regeneration of the osseous defect related to the lesion and resulting surgery.
CLINICAL DISCUSSION
Histologically, the ossifying fibroma is dominated by connective tissue containing cell rich areas with a few fragments of fibrosis. Moreover, in the connective tissue numerous small fragments of spongy and compact bone with areas of partial necrosis present and a significant number of inflammatory cells are observed. Surgical removal of the cyst with thorough curettage of the osseous walls and grafting of the defect provides predictable healing and the desired clinical results sought. Utilization of the biphasic calcium sulfate graft material allows the elimination of the need to overlay the area with a membrane before the flap due to its hard set and the prevention of soft tissue ingrowth into the graft material during the healing phase. Additionally, the hard set of the material allows tenting of the area to maintain the desired volume and ridge contour. Conversion of the graft material depending on the volume placed to host bone occurs over a 3-6 month period.
CONCLUSION
The case report presented, as well as the authors experience mimics the literature on biphasic calcium sulfate in its use as an osseous graft material and is an effective method for the repair of osseous defects that result from the removal of tumors and cysts of the maxilla and mandible. Treatment of an ossifying fibroma is an ideal application of the use of this biphasic calcium sulfate material allowing tenting of the surgical site over the defect created after cyst removal without the need for resorbable collagen membranes. This simplifies its use and decreases material costs that may hamper patient acceptance of treatment without a decrease in expected clinical results.

Cemento-ossifying fibroma is a benign fibro-osseous lesion arising from the periodontal ligament and has the potential to form cementum and bone in the periodontal ligament. Cemento-ossifying fibroma is a painless, pedunculated, or sessile, smooth exophytic growth arising attached to the gingival tissues. We present a case of cemento-ossifying fibroid epulis in the posterior maxilla attached to the interdental gingiva between the 26 and 27 region buccally in a 52-year-old female patient managed with surgical excision of the lesion, extraction of the involved teeth, curettage, and palatal obturator while under general anesthesia. The patient was followed up post-operatively, healing was satisfactory, there were no signs of infection, and no recurrence was noted in the six-month follow-up period.
