Calcified epithelial odontogenic tumour (CEOT) are rare benign tumours that tend to arise in the mandible. Calcifications of amyloid-like substances produced by these tumours present as irregular radiopacities on the radiographs. Herein, we report a rare case of a CEOT in the maxillary premolar, which was largely composed of massive calcification and the presence of an impacted tooth. The patient was a 37-year-old male with a chief complaint of tooth mobility and pain in the left maxillary molar. Panoramic X-rays and computed tomography imaging showed an irregular radiopaque lesion with tooth-like structures in the left maxillary premolar. An excisional biopsy was performed after a clinical diagnosis of a benign tumour was suspected. The lesion was histopathologically diagnosed as a CEOT. The postoperative course was good, and the patient is currently under observation.

Oncocytic metaplasia refers to a metaplastic alteration occurring in duct and acinar cells, typically found in major or minor salivary glands, commonly associated with aging. Despite being infrequently reported, it appears to be an underrecognized phenomenon that may be linked to inflammatory fibrous hyperplasia (IFH). A 66-year-old caucasian female, who is a non-smoker and abstains from alcohol, presented with longstanding multiple nodular lesions along the mucosa of the maxillary alveolar ridge. Clinical examination led to a diagnosis of IFH, which was confirmed through excisional biopsies. Histopathological examination revealed characteristic features of IFH alongside ductal structures exhibiting notable cell hyperplasia with oncocytic metaplasia. These cells displayed an irregular arrangement of single and double-layered structures with cystic dilatation. Additionally, some excretory ducts exhibited focal hyperplasia and thickening. This case underscores the co-occurrence of oncocytic metaplasia with IFH, emphasizing the significance for pathologists to identify such features to prevent misdiagnosis and unwarranted investigations.

Plasmablastic lymphoma (PBL) is a type of non-Hodgkin lymphoma commonly associated with human immunodeficiency virus (HIV) infection. In rare cases, PBL occurrence is noted in the oral cavity of elderly individuals who are HIV negative and EBV positive. The present report describes a case of oral mucosa-type PBL that occurred in the maxillary gingiva of the oral cavity. A 91-year-old male came to our clinic with enlarged swelling of the palatal gingiva of the right maxillary molar. The initial examination showed a smooth-surfaced extraordinary swelling with a diameter of approximately 20 mm. Cytology findings led to a class V determination and the patient was clinically diagnosed with a right-sided maxillary malignant tumor. Imaging studies also revealed a tumor in the right-side submandibular lymph node. For further confirmation of the diagnosis, a tissue biopsy was performed and a diagnosis of PBL determined, based on the histopathological and immunohistological findings of the specimen. Blood test results showed that the patient was HIV negative and EBV positive. Two years after the biopsy, there was no recurrence or enlargement in the affected area noted.
浆细胞性淋巴瘤（PBL）是一种非霍奇金淋巴瘤，通常与人类免疫缺陷病毒（HIV）感染有关。在极少数情况下，HIV 阴性、EBV 阳性的老年人口腔中也会出现浆细胞性淋巴瘤。本报告描述了一例发生在口腔上颌龈的口腔黏膜型 PBL。一名 91 岁的男性因右侧上颌臼齿腭龈肿大来我院就诊。初步检查显示，肿物表面光滑，直径约 20 毫米。细胞学检查结果为 V 级，患者被临床诊断为右侧上颌恶性肿瘤。影像学检查还发现右侧颌下淋巴结有肿瘤。为了进一步确诊，医生对患者进行了组织活检，并根据标本的组织病理学和免疫组织学检查结果，确定其诊断为 PBL。血液检测结果显示，患者的 HIV 阴性，EBV 阳性。活检两年后，患处没有复发或增大。

The incidence of complex maxillomandibular injuries resulting from the intraoral explosion of spherical firecrackers is rare. Restoring oral function, aligning teeth, and achieving optimal aesthetic and functional outcomes are challenging. This case report presents a 34-year-old male patient who self-lit firecrackers in his mouth and suffered comminuted mandibular fracture, dentoalveolar fracture (upper and lower anterior segment), multiple soft tissue injuries, and laceration of lip, adjacent skin, tongue, and oropharyngeal area. Before transferring the patient to oral and maxillofacial surgery unit, urgent intubation, fluid resuscitation, and bleeding control were performed. These traumas require considerable debridement and immediate reconstruction. The patient underwent debridement, irrigation, open reduction, and internal fixation with miniplates. Postoperative functional outcomes were assessed using the University of Washington Quality of Life Questionnaire (UW-QOL) at 3-month, 6-month and 1-year. Functional outcomes, especially swallowing and speech, were satisfactory. The facial soft tissue scar was well hidden, with no functional impairment. Occlusal alignment was achieved, and an acrylic partial denture was used for rehabilitation. The patient did not experience any post-surgical complications such as trismus or microstomia.

A spectrum of surgical management for temporomandibular joint (TMJ) ankylosis exists ranging from gap arthroplasty to total joint replacement. Reconstruction and rehabilitation of the ramus-condyle unit (RCU) remains a surgical challenge in TMJ ankylosis. Distraction osteogenesis (DO) is a promising technique for joint reconstruction over conventional methods. This review compared the clinically relevant outcomes of transport distraction osteogenesis (TDO) and costochondral graft (CCG) for joint reconstruction in TMJ ankylosis.
Methods
PubMed, Medline, Embase, CENTRAL and ScienceDirect databases were searched from inception till 30th September 2023. Randomized controlled trials (RCTs) and prospective, retrospective studies on TMJ ankylosis patients comparing TDO and CCG for joint reconstruction and reporting outcomes were included. Assessment of the risk of bias was done with the Cochrane Collaboration tool.
Results
Five studies were included in the review. A significant improvement in the postoperative mouth opening with both groups was reported on follow-up and the analysis favored TDO for the joint reconstruction (p = 0.003). TDO group reported up to 6.1 % lower incidence of postoperative reankylosis in comparison to CCG (p = 0.59). Data was insufficient with regard to facial asymmetry, chin deviation and malocclusion.
Conclusion
TDO is a better alternative to CCG for joint reconstruction. Due to paucity of the reported literature and unequal sample distribution between the groups, quality evidence could not be derived regarding long-term stability. Further RCTs are recommended to generate better evidence and evaluate clinically relevant outcomes.

Carbonate apatite (CO3Ap)-granules bone substitute exhibits excellent osteoconductivity and replaced by a new bone based on bone remodeling process. However, no improvement has been made so far with respect to the drawbacks of granules; i.e., intraoperative scatter and postoperative migration. The aim of this study was to evaluate the feasibility of fabricating a CO3Ap-granules sponge to overcome these drawbacks. The CO3Ap granules sponge was successfully fabricated by mixing 300–600 µm CO3Ap granules with 3 % atelocollagen, followed by lyophilization at − 70 °C for 24 h and a dehydrothermal treatment at 150 °C for 24 h. The CO3Ap-granules sponge and CO3Ap-granules were implanted into rat calvarial bone defects for 2 and 4 weeks. No significant intraoperative scatter and postoperative migration were evident when the bone defects were reconstructed with the CO3Ap-granules sponge, whereas significant both intraoperative scatter and postoperative migration were observed when the bone defect was reconstructed with CO3Ap granules. Although less osteogenesis was anticipated for the CO3Ap-granules sponge due to the coverage of CO3Ap-granules surface with atelocollagen, no significant differences were observed in bone formation between the CO3Ap-granules sponge and CO3Ap-granules cases because the 3 % atelocollagen and lyophilization kept the CO3Ap granules surface only partially covered. Consequently, the CO3Ap-granules sponge and CO3Ap-granules exhibited similar bone formation at both 2 and 4 weeks after surgery. Thus, the CO3Ap-granules sponge improved the handling performance and retention ability at the bone defects without scarifying the osteogenesis of CO3Ap-granules.

Objective
Oral cancers have varied clinical presentations, often leading to repeated and multiple biopsies to establish diagnosis and formulate treatment. Use of portable, office- based tools to help in diagnosis and biopsies can result in early diagnosis. We used a fluorescence-based device to study its efficacy in malignant and potentially malignant disorders of oral cavity.
Method
50 individuals including 41 patients and 9 controls were enrolled. Following a thorough clinical examination, the Oralscan® device (with combined autofluorescence and diffuse reflectance) was used for characterization of these lesion and to assist in biopsy taking. The zones (red/yellow/green) in which the lesion(s) fell were noted. Punch biopsies were performed and pathological reports were compared with the zonal category as given by the device.
Results
The most common site of involvement was buccal mucosa (70.7 %). The total number of lesions studied was 59, with 143 images captured in toto. 75.6 % of cases were malignant. The overall sensitivity, accuracy and PPV of the device was 43.24 %, 34.04 % and 61.54 % respectively.
Conclusion
The present study showed that the use of the autofluorescence and diffuse reflectance handheld device had poor sensitivity and specificity for diagnosing oral lesions both malignant and potentially malignant disorders of oral cavity.

Le Fort I osteotomy combined with horseshoe osteotomy has been established as a technique for total maxillary setback. In this study, the stability of the maxillary and mandibular positions was examined in five cases in which was performed total maxillary setback by Le Fort I osteotomy combined with horseshoe osteotomy.
Subjects and methods
The stability of the maxilla was examined in five cases that had undergone total maxillary setback by horseshoe Le Fort I (H- LF I) osteotomy and bilateral sagittal split osteotomy (BSSO) including mandibular anterior subapical osteotomy (MASO) in one case. The changes in the position of the maxillary and mandibular positions were analyzed with lateral cephalograms taken immediately before (T0), a few days after (T1), and one year after (T2) the surgery.
Results
Postoperative maxillary changes both horizontally and vertically were all less than 2 mm. Postoperative horizontal mandibular changes showed little skeletal relapse, but all postoperative vertical mandibular changes were within 2 mm.
Conclusion
Our results suggest that H-LF I osteotomy is a reliable, safe, and effective surgical procedure for postoperative skeletal stability of total maxillary setback in skeletal class II cases.

Central Giant Cell Granuloma (CGCG) in jaw bones have characteristic diagnostic features. But rarely they may present with slightly different features or features related to other lesions. It can be challenging when histopathological features of two or more different entities are seen within a single lesion.
Case report
We report a jaw lesion in a 47-year-old male patient who presented unusually as a painful diffuse left mandibular swelling. Although the 2-dimensional imaging study suggested a cystic lesion, the 3-dimensional imaging study pointed to a more well-demarcated pathology. A complete excision of the lesion when examined in detail confirmed a histopathologic diagnosis of a CGCG. The challenge however was the large reactive bone areas that raised a suspicion of an Ossifying Fibroma lesion.
Conclusion
Diagnosing a jaw lesion consisting of areas showing two or more different features is always challenging. This report highlights the key histopathologic findings that can help distinguish between a hybrid lesion and a case of CGCG with large reactive bone areas.

Supernumerary teeth are commonly observed in the anterior region of the maxilla; however, reports of their occurrence in the molar region, particularly near the third molars, are rare. A 21-year-old man with no genetic disease visited our department for a third-molar extraction. Panoramic radiography and computed tomography revealed one and four supernumerary teeth in the right and left maxillary third-molar regions, respectively. The bilateral third molars and supernumerary teeth were extracted under general anesthesia. The supernumerary teeth were incompletely developed, and one tooth morphologically resembled a premolar. The patient’s postoperative course was uneventful.
