Abstract
The study aimed to retrospectively analyze the reduction pattern of odontogenic keratocysts (OKCs) after decompression, followed by enucleation (EN), peripheral ostectomy (PO), and Carnoy's solution (CS) to establish the appropriate time for inserting implants, along with assessing the long-term success of conservative treatment with adjunctive therapy. The predictable variables were the reduction pattern and the study's treatment option. The outcome variable was the volumetric changes in the size of bony defects. These changes were determined using a percentage difference and a reduction rate. They were recorded after decompression and one, three, six, twelve, and eighteen months after EN. P-values of .05 were considered significant. The study included 66 patients with 71 OKCs. Males, younger ages, and mandibular OKCs significantly predominated. The decompression significantly changed the initial volume from 135.40 ± 1.2 cm3 to 101.55 ± 0.1 cm3 with 28.6 percentage difference and 25% reduction rate. At the end of the first and third months after EN, the reduction pattern is 50.0%-75.5% of the initial volume, with no significant prediction for the direction of the reduction pattern. After 18 months, all bony defects disappeared, with no recurrences for the next 18 years. In conclusion, the reduction pattern is 75.5% of its initial volume at the end of the third month after OKC management. Therefore, within the limitations of the study, its treatment approach seems to be an option amongst other protocols that includes a view to early implant based dental rehabilitation.

Abstract
This study aimed to develop a high-performance deep learning algorithm to differentiate Stafne’s bone cavity (SBC) from cysts and tumors of the jaw based on images acquired from various panoramic radiographic systems. Data sets included 176 Stafne’s bone cavities and 282 odontogenic cysts and tumors of the mandible (98 dentigerous cysts, 91 odontogenic keratocysts, and 93 ameloblastomas) that required surgical removal. Panoramic radiographs were obtained using three different imaging systems. The trained model showed 99.25% accuracy, 98.08% sensitivity, and 100% specificity for SBC classification and resulted in one misclassified SBC case. The algorithm was approved to recognize the typical imaging features of SBC in panoramic radiography regardless of the imaging system when traced back with Grad-Cam and Guided Grad-Cam methods. The deep learning model for SBC differentiating from odontogenic cysts and tumors showed high performance with images obtained from multiple panoramic systems. The present algorithm is expected to be a useful tool for clinicians, as it diagnoses SBCs in panoramic radiography to prevent unnecessary examinations for patients. Additionally, it would provide support for clinicians to determine further examinations or referrals to surgeons for cases where even experts are unsure of diagnosis using panoramic radiography alone.

Abstract
BACKGROUND Alcohol (EtOH) intake during adolescence has become an important public health issue. Although the detrimental effects of EtOH intake on the musculoskeletal system are well known, only a few studies have investigated its impact on the stomatognathic system of adolescents. This study aimed to investigate the effect of EtOH binge drinking on the alveolar bone and the long-term consequences after abstinence. METHODS Adolescent female Wistar rats (35 days old) were exposed to 4 cycles of EtOH binge drinking (3 g/kg/d; 3 days On-4 days Off) or distilled water (control group). Alveolar bone micromorphology and vertical bone distance were evaluated at 1, 30, and 60 days after that last EtOH intake through X-ray computed microtomography. The mineral:matrix ratio was assessed through Raman spectroscopy. RESULTS A decrease in both trabecular thickness and volume ratio, and an increase in trabecular separation were observed at the 1-day evaluation (immediate withdrawal). After 30 and 60 days, the alveolar bone parameters were found similar to control, except for the mineral:matrix ratio in the long-term abstinence. CONCLUSIONS EtOH binge drinking during adolescence results in alveolar bone damage that may persist in adulthood, even after abstinence.

Abstract
Buccal bifurcation cyst (BBC) is a rare inflammatory odontogenic cyst, which commonly affects children in the first decade of life. We report a case of a seven-year-old healthy boy with bilateral BBC, which involved unerupted incomplete permanent mandibular first molars. A review of the literature in English language revealed few similar cases. We reviewed 16 manuscripts of bilateral mandibular BBC, reporting a total of 20 cases since 1970. The clinical features of bilateral mandibular BBC summarized here could assist specialists with an accurate diagnosis and provide patients with optimal management.

Abstract
PURPOSE We aim to characterize the quantitative dynamic contrast-enhanced (DCE) magnetic resonance imaging (MRI) parameters associated with advanced mandibular osteoradionecrosis (ORN) compared with the contralateral normal mandible. METHODS AND MATERIALS Patients with a diagnosis of advanced ORN after curative-intent radiation treatment of head and neck cancer were prospectively enrolled after institutional review board approval and study-specific informed consent were obtained. Quantitative maps generated with the Tofts and extended Tofts pharmacokinetic models were used for analysis. Manual segmentation of advanced ORN 3-dimensional volume was done using anatomic sequences to create ORN volumes of interest (VOIs). Subsequently, normal mandibular VOIs were segmented on the contralateral healthy mandible of similar volume and anatomic location to create control VOIs. Finally, anatomic sequences were coregistered to DCE sequences, and contours were propagated to the respective parameter maps. RESULTS Thirty patients were included. The median time to ORN diagnosis after completion of IMRT was 38 months (range, 6-184 months), whereas median time to ORN progression to advanced grade after initial diagnosis was 5.6 months (range, 0-128 months). There were statistically significant higher Ktrans and Ve in ORN-VOIs compared with controls (0.23 vs 0.07 min-1, and 0.34 vs 0.15; P < .0001 for both). The average relative increase of Ktrans in ORN-VOIs was 3.2-fold higher than healthy mandibular control VOIs. Moreover, the corresponding rise of Ve in ORN-VOIs was 2.7-fold higher than in the controls. Using combined Ktrans and Ve parameters, 27 patients (90%) had at least a 200% increase of either of the studied parameters in the ORN-VOIs compared with their healthy mandible VOIs. CONCLUSIONS Our results confirm that there is a quantitatively significant higher degree of leakiness in the mandibular vasculature as measured using DCE-MRI parameters of areas with advanced ORN versus healthy mandible.

Abstract
BACKGROUND/OBJECTIVE In this retrospective study, we aimed to investigate a new 3D evaluation method for evaluating bone regeneration after cystectomy of odontogenic cysts. METHODS The study included 26 patients who underwent cystectomies between 2012 and 2017 and had received either fillings or non-fillings with autologous iliac crest. Bony regeneration was analyzed using 3D imaging software and comparing identical regions of interest (ROIs) that were determined by exact overlays of the postoperative cone beam computer tomography (CBCT) or computer tomography (CT) images. Outcome measures, including volume changes according to the defect size and configuration, patient age, the entity and distribution of the cysts, were collected. RESULTS Twenty-six patients (5 women and 21 men) had 30 defects, including nine keratocysts, seven radicular cysts and 14 dentigerous cysts. A total of 73% of the defects were in the mandible. The mean 3D follow-up time was 12 months. According to the 3D evaluation of bony regeneration, the defect size and configuration showed no significant differences between the groups (filled or non-filled with 15 defects per group). CONCLUSIONS By establishing a standardized 3D method for evaluating bone regeneration, healing can be better monitored and evaluated.

Abstract
INTRODUCTION The odontogenic keratocyst (OKC), previously known as keratocystic odontogenic tumor has been the most disputable pathologies of the maxillofacial region. Patients with OKC are often asymptomatic but may present with pain, swelling, or discharge. Despite the aggressive nature, previous literature as early as 1970s reported the fact that parakeratinized OKC can be treated by means of marsupialization alone. PATIENTS CONCERNS The patient had reported with a complaint of pain and swelling in relation with a tooth in mandibular right quadrant. DIAGNOSIS This case report discusses features of a rare, extensive, panmandibular OKC that is only second of its kind mentioned in the literature. INTERVENTION As a usual treatment protocol, marsupialization was attempted first. Immunohistochemical analysis revealed reduced expression of Ki-67 and B cell lymphoma 2 (bcl-2) markers after marsupialization from 2 separate sites. However, due to incomplete resolution in the lower right anterior region, an aggressive approach was taken by curetting it out surgically along with associated teeth and cortical plate followed by application of Carnoy's solution. OUTCOME Postsurgery uneventful healing of the lesion was noted on regular follow-up visits with complete resolution at 40 months. The case has been followed for 10 years with no sign of relapse and reoccurrence. CONCLUSIONS Based on the expression of markers it can thus be concluded that Ki-67 and bcl-2 are site specific and bear strong relationship with the recurrence of OKCs.

Abstract
BACKGROUND Central giant cell granulomas are benign tumours of the mandible, presenting in children and young adults. Divided into non- and aggressive subtypes, the aggressive subtype is relatively rare and can occasionally progress rapidly, resulting in significant morbidity. CASE PRESENTATION We present a case of an aggressive central giant cell granuloma (CGCG) in a six year-old female. The lesion originated in the right mandibular ramus and progressed rapidly to involve the condyle. Diagnosis was made using a combination of imaging and pathology. A timely en bloc resection of the hemi-mandible was performed with placement of a reconstructive titanium plate and condylar prosthesis. CONCLUSION Our case demonstrates the importance of considering CGCG in the differential diagnosis of rapidly progressive mandibular lesions in the pediatric population. Prompt diagnosis and management can greatly improve long-term outcomes.

Abstract
BACKGROUND Diffuse sclerosing osteomyelitis (DSO) is a non-purulent chronic recurrent inflammation and affects the mandible in many cases. Belonging to the group of autoinflammatory diseases, in children and in cases with various additional symptoms including synovitis, acne, pustulosis, hyerostosis, and osteitis (SAPHO syndrome), therapy usually consists of non-surgical treatment. Against this background, we present an unusual course of DSO in an adult female patient. CASE REPORT A 50-year-old female suffering from DSO without SAPHO syndrome was pretreated for years with conservative drug regimens and local surgery. Previous therapy was not successful, and subsequently, multiple surgical procedures were carried out focused on recurrent acute exacerbations of DSO. Surgery resulted in a total resection and alloplastic and autoplastic reconstruction of the mandible including both temporomandibular joints. Prosthetic rehabilitation was possible after dental implant loading, and the final outcome was very satisfactory. CONCLUSION In the event that non-surgical options are not successful in DSO, an extended surgical therapy becomes necessary. Even if surgery results in complete resection of the mandible, a satisfactory rehabilitation can be achieved after complex reconstruction.

Abstract
OBJECTIVES Low-intensity pulsed ultrasound (LIPUS) combined with porous scaffolds can be used as a new therapy to treat bone defect repair. The aim of this study was to evaluate the effects of 1 and 3.2 MHz LIPUS on osteogenesis on porous Ti64 alloy scaffolds for both in vitro and in vivo studies. METHODS Scaffolds were randomly divided into the high-frequency ultrasound group, low-frequency ultrasound group, and control group. Mouse pre-osteoblast cells were cultured with porous Ti-6Al-4V scaffolds in vitro to evaluate cell proliferation and differentiation. In addition, scaffolds were implanted into rabbit mandibular defects in vivo. The effects of LIPUS on bone regeneration were evaluated by observing the micro-computed tomography (micro-CT), toluidine blue staining, and von Kossa staining. RESULTS The results revealed no significant difference in the cell counting kit-8 values between the ultrasound groups and control groups (P > .05). Compared with the control group, ultrasound promoted alkaline phosphatase activity and osteocalcin levels of the cells on the scaffolds (P < .05), but there was no significant difference between the two frequencies. In addition, histomorphologic analyses revealed that the volume and amount of new bone formation increased and that bone maturity improved in the ultrasound groups compared with the control group, but no significant difference was noted between the two frequencies. CONCLUSIONS Under the present experimental conditions, LIPUS promoted osteoblast differentiation and promoted bone maturity on porous Ti64 scaffolds. No significant differences were noted between the two frequencies.

Abstract
Alveolar bone resorption has been a major challenge for implant placement in regions limited by anatomical structures. New alternatives have been introduced with the inclusion of extra-short implants in dentistry. The association of guided bone regeneration (GBR) with the use of extra-short implants might be a viable alternative for regions with limited bone height. This case report aimed to present the rehabilitation of a patient with severe mandibular bone resorption in the posterior region. The association of GBR with the use of extra-short implants was a viable alternative after a 3-year follow-up.

Abstract
Osteosclerotic lesions are a common finding on dental radiographs. They are considered developmental variants of a normal bone architecture and they usually do not need any treatment. The purpose of this article is to present a rare case of osteosclerotic lesion of the mandible causing trigeminal neuropathy by compression of the alveolar nerve. The pain started with dental hypersensitivity of the mandibular right first molar. Later on, signs of irreversible molar tooth pulpitis developed. Endodontic therapy and apicoectomy did not resolve the pain, which later intensified, and painful neuropathy localized to inferior alveolar nerve developed; therefore, surgical decompression was indicated. Treating a dental patient with neuralgic pain is always a challenge, especially if there is no obvious source or reason for this type of pain. A clear evaluation and treatment protocol are important to minimize the patient's morbidity and avoid unnecessary overtreatment.

Abstract
Hyperparathyroidism (HPT) is an endocrine metabolic disorder characterized by increased secretion of parathyroid hormone. Untreated secondary HPT leads to renal osteodystrophy (ROD). Facial skeletal abnormalities in patients with ROD are rare. The purpose of this paper is to report a conservative surgical approach of exuberant osteitis fibrosa lesions in patient with chronic kidney disease. A 24-year-old female was referred to maxillofacial surgery department with giants ROD affecting palate, maxilla, and mandible, resulting in esthetic and functional impairment. The pathogeneses and multidisciplinary management of ROD are discussed with a brief literature review. Eight years after the conservative treatment of exuberant jaw lesions, no noticeable bone changes were observed in the patient. A multidisciplinary therapy is essential for correct diagnosis of ROD and optimal multimodality treatment. The conservative management was an efficient alternative for the success of the case reported.

Abstract
Lingual mandibular bone depressions mainly affect the posterior region of the mandible. Depressions in the anterior region are rare, frequently posing difficulties in diagnosis. The aim of this article is to present a case of an anterior lingual mandibular bone depression (ALMBD) that was radiographically superimposed on the roots of anterior teeth. A 43-year-old man was referred for evaluation of a slight depression on the lingual surface of the anterior mandible. The depression was associated with a well-defined radiolucent area superimposed on the roots of the right canine and incisors. All teeth in the area proved to be vital, and cone beam computed tomography (CBCT) revealed a lingual depression in the area. The final diagnosis was an ALMBD, and the patient underwent clinical and radiographic follow-up examinations for 22 months that revealed no alterations in the area. When anterior mandibular radiolucencies are superimposed on the roots of the adjacent teeth, ALMBDs should be considered in the differential diagnosis along with periapical cysts and granulomas. Radiographic and CBCT analyses are useful to avoid unnecessary endodontic and surgical approaches.

Abstract
After reconstruction of a segmental mandibular defect with a fibular free flap, a vascular crisis can be detected clinically and a "no-flow" phenomenon found during re-exploration. Traditional methods used to solve this include removal of the failed flap and delayed mandibular reconstruction, or restoration of the defect with a functional reconstruction plate or contralateral fibular free flap. Our aim therefore was to investigate under what circumstances it is feasible to use a non-vascularised fibular bone graft (NVFB) as a free bone graft after the failure of a vascularised fibular free flap. From 1 January 2010-31 December 2014, 10 patients who had NVFB after failure of a fibular free flap were included in the study. All patients were treated at the Peking University School and Hospital of Stomatology. NVFB were preserved successfully without infection in all 10 cases, and follow-up imaging showed that it had incorporated well with the residual mandible, the basic function and facial aesthetics of which were maintained. In conclusion we have identified that by precise selection of patients, detailed preoperative planning, and meticulous postoperative care, NVFB can be used as a "rescue" technique after failure of a fibular free flap, and can successfully restore the segmental mandibular defect and facial contour.

Abstract
OBJECTIVE Pain is one of the most problematic symptoms in patients with osteoradionecrosis of the jaws. This study investigated the associations between pain severity and morphologic alterations of the mandibular canal and inferior alveolar nerve, in respective computerized tomography images and resected specimens of mandibular osteoradionecrosis. STUDY DESIGN We assessed 14 lesions in 13 patients who underwent segmental mandibulectomy for surgical debridement and simultaneous reconstruction with free fibula flap (1 patient exhibited bilateral lesions). The extent of the mandibular canal bone defect on preoperative coronal computerized tomography images and the number of inferior alveolar nerve fascicles in resected specimens were evaluated. Comparisons were made between the slight pain and extreme pain groups. In most of the patients in the extreme pain group, either mandibular canal bone defects were absent or entire circumferential defects were present; inferior alveolar nerve fascicles were either distinguishable or completely absent in the resected specimens. RESULTS Although there was no statistically significant association between extreme pain and computerized tomography or histopathologic findings, the histopathologically indistinguishable inferior alveolar nerve fascicles was significantly associated with slight pain. CONCLUSIONS The degree of degeneration of mandibular canal and inferior alveolar nerve may be associated with pain severity in patients with mandibular osteoradionecrosis.

Abstract
In an 80-year-old man, a radiolucent laesion was seen on the panoramic radiograph of the right mandible. The localisation of the radiolucent laesion under the mandibular canal and the additional finding of fatty tissue or submandibular salivary gland in the concavity on the cone beam computed tomography are virtually probative for a Stafne cyst.

Abstract
Langerhans cell histiocytosis (LCH) is the latest terminology for a disorder of reticulo-endothelial system, previously known as histiocytosis X, and marked by aberrant proliferation of bone marrow derived Langerhans cells with variable inflammatory infiltrate including neutrophils, lymphocytes, plasma cells, eosinophils, and multinucleated giant cells. Although rare, the disorder frequently inflicts children with peak incidence recorded in 2-4 years age group. LCH is rare in adults. A22-year adult male presented with the complaint of teeth mobility. Orthopantomogram (OPG) revealed multiple extensive osteolytic lesions destroying both jaws. Giant cell granuloma, Paget's disease and LCH, along with other vanishing bone disorders (Gorham Stout disease and Winchester syndrome) were suspected differentials. Multiple incisional biopsies were performed and a diagnosis of LCH was confirmed by routine histopathological analysis followed by immunohistochemical staining for S-100 and CD1a.

Abstract
We report a case of a 48-year-old male patient with "krokodil" drug-related osteonecrosis of both jaws. Patient history included 1.5 years of "krokodil" use, with 8-month drug withdrawal prior to surgery. The patient was HCV positive. On the maxilla, sequestrectomy was performed. On the mandible, sequestrectomy was combined with bone resection. From ramus to ramus, segmental defect was formed, which was not reconstructed with any method. Post-operative follow-up period was 3 years and no disease recurrence was noted. On 3-year post-operative orthopantomogram, newly formed mandibular bone was found. This phenomenon shows that spontaneous bone formation is possible after mandible segmental resection in osteonecrosis patients.

Abstract
The Stafne bone defect, also known as the Stafne bone cyst, or Stafne bone cavity, is an asymptomatic, static depression of the lingual aspect of the mandible that often appears as a radiolucent area near the angle of the mandible. It noted as an incidental finding during routine dental imaging. The purpose of this article is to present a case that was diagnosed as a Stafne bone defect using Cone Beam Computed Tomography (CBCT). This diagnosis is based on radiographic characteristics, which are described as a well-defined, round to ovoid radiolucent lesion in the lower left mandible, located below the inferior alveolar nerve canal and anterior to the angle of the mandible. Radiographic confirmation should preclude further surgical exploration.

Abstract
The Stafne defect is a benign, asymptomatic, non-progressive and rare bone depression, mainly discovered by chance in the posterior mandibular region. It is described radiographically as an oval radiolucency located below the mandibular canal, in the molar region, close to the submandibular gland. Sialography is a traditional technique in the radiographic examination of salivary glands that involves the injection of an iodine-based contrast medium into the main salivary duct. The Cone Beam Computed Tomography (CBCT) is a 3D imaging technique that has modernized the dental and maxillofacial practice with its advantages such as high speed, good spatial resolution and low radiation exposure. The CBCT Sialography that consists in a 3D Sialography with cone beam offers the same benefits as traditional sialography and allows three-dimensional viewing. It is a new imaging test for an accurate anatomical study of the major salivary glands and their relationships with their environments. The aim of this report is to present a case of Stafne bone cavity containing right submandibular gland tissue, occurring in a 58-year-old man and diagnosed by using CBCT sialography.

Abstract
OBJECTIVE To assess possible associations between torus palatinus (TP), torus mandibularis (TM), occlusal force (OF), Klemetti's classes, mandibular cortical index (MCI), and sociodemographic variables in a selected sample of Jordanians. Previous studies have suggested that oral tori are benign anatomical variations probably related to several factors such as functional stress, gender predisposition, number of teeth present, and nutritional factors. METHOD AND MATERIALS A total of 130 Jordanian adults were included. Shape, location, and appearance of tori were recorded from study casts. Size was measured using digital calipers. OF was recorded in Newtons. MCI and Klemetti's classification were assessed using panoramic radiographs. Data were statistically analyzed, and level of significance was set at P < .05. RESULTS The mean ± SD recorded OF was 524 ± 183 N in the tori group, compared to 417 ± 172 N in controls (P = .001). OF was significantly higher in males compared to females (P < .001), and was significantly higher in subjects with TM only (543 ± 201 N) (P < .001). TP and TM were predominantly more than 6 mm in size. The average OF in subjects with Klemetti class 3 was 418 ± 174 N, while OF in Klemetti class 1 subjects amounted to 535 ± 187 N (P = .043). CONCLUSION Average OF was significantly higher in tori subjects and in males (if compared to controls and female subjects, respectively). The presence of oral tori, Klemetti's classification, and MCI ratio seems to be positively correlated with OF.

Abstract
The lateral periodontal cyst is a rare benign lesion that is generally asymptomatic and commonly discovered by routine intraoral radiography. Reports on proper management of this lesion are readily available. However, the literature is sparse regarding the long-term outcomes following surgery. A traditional radiographic technique does not provide an adequate image of the healing, and a patient may resist the prospect of a reentry procedure. The current report is the first to utilize a cone-beam computed tomography scan to evaluate the healing potential of a freeze-dried bone allograft approximately 18 months postoperatively.

Abstract
BACKGROUND Secondary hyperparathyroidism is a frequent complication of chronic renal failure. The brown tumor is an unusual presentation of fibrous osteitis that represents a serious complication of renal osteodystrophy, affecting predominantly the hands, feet, skull, and facial bones. CASE REPORT The aim of this paper is to describe the case of a 53-year-old female patient, with renal failure who has been on dialysis for 6 years and developed severe secondary hyperparathyroidism and brown tumor of the maxilla and mandible, confirmed by incisional biopsy. Parathyroidectomy was indicated as a result of rapid growth of the tumor and the maintenance of laboratory findings. Despite the normalization of serum parathyroid hormone and alkaline phosphatase, tumor regression was slow and patient's important functional and esthetic deficits persisted. Excision of the mandible tumor was conservative. Osteoplasty was recommended because during a 5-year follow-up there was regression of the lesion, decreased pain, bleeding, and tooth mobility.

Abstract
BACKGROUND Mandibular coronoid hyperplasia is a rare condition associated with gradual reduction in mouth opening. Its aetiology is unknown but increased temporalis activity, endocrine stimulus, trauma and familial causes have been proposed. CASE REPORT In this article, we present a case of bilateral coronoid hyperplasia presenting with limited mouth opening in 16-year-old Caucasian twin sisters. DISCUSSION This report gives a new perspective to the aetiology of coronoid hyperplasia since it describes its occurrence in monozygotic twins and hence provides a strong argument in support of a genetic aetiology.

Abstract
Stafne bone cavity (SBC) is an uncommon lesion of the mandible; and generally found incidentally on routine radiographic examinations. The radiographic differential diagnosis of SBC includes a variety of lesions including odontogenic cysts, benign tumors, or bone metastases. In the present case, a 22-year female patient was admitted with chief complaint of pain in the right mandibular molar area. On panoramic radiographic examination, a non-specific large radiolucent lesion related to mandibular molar teeth was detected and extra-oral surgical intervention was planned. However, on examination with cone-beam CT(CBCT), a SBC was suspected due to lack of lingual cortical plate; and intraoral surgical exploration confirmed the diagnosis showing a cavity with small inflamed salivary gland tissue. Examination with CBCTon suspicious jaw lesions helps avoid unnecessary extraoral surgical interventions.

Abstract
The masticator space is located between the masseteric fascia and the pterygoid muscle fascia. Here we report two cases of masticator space abscesses spreading from infections of mandibular teeth. Case 1 is an 85-year-old lady who were referred to Yokohama City University Hospital with a left-cheek swelling and trismus. An enhanced CT scan revealed an abscess extending from the left infratemporal fossa to the temporal fossa. A purulent discharge was observed from her left lower gingiva. We performed surgical drainage under general anesthesia. After infection control, the affected teeth were extracted. Case 2 is an 82-year-old lady who was administered oral bisphosphonate for osteoporosis. She presented to another hospital with fever, trismus and swelling anterior to the right ear after right lower tooth extraction. Because MRI revealed persistent osteomyelitis of her mandible even after antibiotic treatment, she was referred to us. Enhanced CT showed an abscess in the right infratemporal fossa. After surgical drainage similar to Case 1, antibiotics were administered for approximately 4 months to control the osteomyelitis. It is important to recognize that infections of the mandibular teeth can cause an abscess in the masticator space through the pterygomandibular and infratemporal spaces.

Abstract
Keratocystic odontogenic tumors (KCOTs) are known for unique and varied behavior, high recurrence rates, and distinctive histopathologic findings. Differential diagnosis and management of KCOTs may be challenging because other jaw lesions may present similar characteristics. Careful interpretation of cone beam computed tomograms and magnetic resonance images has great significance for precise assessment of KCOTs and their relationships to adjacent anatomic structures as well as for treatment planning. This case report describes a KCOT that developed in the left angle and mandibular ramus in association with a semierupted third molar.

Abstract
Incidental radiopacities of the jaws are commonly identified on routine intraoral and extraoral radiographs. Dentists should be able to develop a differential diagnosis of these lesions. This article presents 2 cases in which mandibular radiopacities associated with external root resorption were identified incidentally and discusses the differential diagnosis of these lesions. Both patients were referred by their general practitioners to dental specialists for further evaluation of homogenous osteosclerotic foci surrounding and resorbing the roots of the permanent mandibular right first molar. The lesions were asymptomatic, caused no cortical expansion, and were static over time. The clinical and radiographic features were consistent with a diagnosis of idiopathic osteosclerosis (IO). External root resorption is present in 10%-12% of cases of IO and often involves the permanent mandibular first molars.

Abstract
A central giant cell granuloma (CGCG) is typically regarded as a benign lesion with osteoclastic activity. Treatment often involves surgical procedures that may cause deformities; however, minimally invasive approaches have been suggested for treating pediatric patients. We report a case of CGCG of the mandible in a 13-year-old boy who presented with a well-defined radiolucent area in the anterior mandible that was initially detected in a radiographic examination for orthodontic purposes. An incisional biopsy was performed and diagnosed histologically as a CGCG. The patient underwent clinical and radiographic follow-up only after the biopsy, eventually showing signs of bone healing. Five years later, complete resolution of the lesion was observed radiographically. Considering this optimal outcome, similar cases of CGCG should be carefully analyzed for appropriateness of this conservative approach.

Abstract
Anatomical landmark detection plays an important role in medical image analysis, e.g. for registration, segmentation and quantitative analysis. Among the various existing methods for landmark detection, regression-based methods have recently attracted much attention due to their robustness and efficiency. In these methods, landmarks are localised through voting from all image voxels, which is completely different from the classification-based methods that use voxel-wise classification to detect landmarks. Despite their robustness, the accuracy of regression-based landmark detection methods is often limited due to (1) the inclusion of uninformative image voxels in the voting procedure, and (2) the lack of effective ways to incorporate inter-landmark spatial dependency into the detection step. In this paper, we propose a collaborative landmark detection framework to address these limitations. The concept of collaboration is reflected in two aspects. (1) Multi-resolution collaboration. A multi-resolution strategy is proposed to hierarchically localise landmarks by gradually excluding uninformative votes from faraway voxels. Moreover, for informative voxels near the landmark, a spherical sampling strategy is also designed at the training stage to improve their prediction accuracy. (2) Inter-landmark collaboration. A confidence-based landmark detection strategy is proposed to improve the detection accuracy of 'difficult-to-detect' landmarks by using spatial guidance from 'easy-to-detect' landmarks. To evaluate our method, we conducted experiments extensively on three datasets for detecting prostate landmarks and head & neck landmarks in computed tomography images, and also dental landmarks in cone beam computed tomography images. The results show the effectiveness of our collaborative landmark detection framework in improving landmark detection accuracy, compared to other state-of-the-art methods.

Abstract
Radiolucencies of the jaws are a common finding. Mostly, they are isolated findings associated with inflammatory processes and consistent with inflammatory periapical disease, such as periapical cysts and periapical granulomas. If associated with the crowns of unerupted teeth, they may represent dentigerous cysts. However, occasionally, larger lytic/radiolucent lesions are identified; even more infrequently, these radiographic findings may be multiple and concurrent. The purpose of this report is to present the case of a 6-year-old female patient with no known concomitant syndrome who presented with multiple intraoral swellings and to discuss the treatment of multiple, bilateral mandibular and maxillary radiolucencies.

Abstract
We present an uncommon diagnosis in a 34-year-old female with a non-healing extraction socket. Incisional biopsy revealed multi-nucleated giant cells suggestive of central giant cell granuloma (CGCG). The computed tomography (CT) report made incidental note of a parathyroid mass. The parathyroid hormone (PTH) level was checked and found to be abnormally high. A diagnosis of brown tumour of the mandible was made. The patient was referred to a head and neck surgeon and the parathyroid mass was removed. The mandibular lesion was managed conservatively and continues to regress post-normalisation of PTH levels. The inclusion of the parathyroid region on the CT scan in this case was fortuitous. There are a range of pathologies containing multinucleated giant cells that can arise from the maxillofacial region; PTH level should, nevertheless, be checked in all such jaw lesions. This allows the clinician to exclude brown tumour from the diagnostic sieve.
