Abstract
PURPOSE To investigate the potential reconstruction of complex maxillofacial defects using computer-aided design 3D-printed polymeric scaffolds by defining the production process, simulating the surgical procedure, and explore the feasibility and reproducibility of the whole algorithm. METHODS This a preclinical study to investigate feasibility, reproducibility and efficacy of the reconstruction algorithm proposed. It encompassed 3 phases: (1) scaffold production (CAD and 3D-printing in polylactic acid); (2) surgical simulation on cadaver heads (navigation-guided osteotomies and scaffold fixation); (3) assessment of reconstruction (bone and occlusal morphological conformance, symmetry, and mechanical stress tests). RESULTS Six cadaver heads were dissected. Six types of defects (3 mandibular and 3 maxillary) with different degree of complexity were tested. In all case the reconstruction algorithm could be successfully completed. Bone morphological conformance was optimal while the occlusal one was slightly higher. Mechanical stress tests were good (mean value, 318.6 and 286.4 N for maxillary and mandibular defects, respectively). CONCLUSIONS Our reconstructive algorithm was feasible and reproducible in a preclinical setting. Functional and aesthetic outcomes were satisfactory independently of the complexity of the defect.

Abstract
PURPOSE Dental origin constitutes most chronic unilateral maxillary sinusitis (CMS) and is referred to as dental chronic maxillary sinusitis (DCMS). Recently, dental implants and related surgical procedures have become more prevalent. We present an evaluation of the simultaneous treatment of DCMS. MATERIALS AND METHODS A retrospective review of records from 395 patients with CMS treated at our medical center from 2015 to 2020 found 65 patients diagnosed with DCMS. Statistical analyses were performed using the records data. RESULTS Four patients were excluded. The final study population included 35 males and 26 females with a mean age of 55. 29 % were post-dental implant placement or related pre-prosthetic procedures. Presenting symptoms included middle meatus edema (72 %), pus in the middle meatus (70 %), and nasal secretion (39 %). Clinical findings included septal deviation (39 %), among them 87 % deviated toward the diseased sinus, OAF (49 %), and nasal polyposis (16 %). In 32 patients, the OAF was closed in one layer using a local mucoperiosteal flap. In 29 patients, the closure was done in two layers, including a buccal fat pad (BFP) regional flap. One patient had a reopened OAF, and five patients required revision surgery. 92 % of patients in this study had complete clinical and radiological resolution of the DCMS. CONCLUSIONS Relevance of nasal septal deviation in association with DCMS is present. There is no distinct difference in the manner of OAF closure if it is done in a simultaneous procedure. One stage combined multidisciplinary surgical procedure is sufficient to treat DCMS.

Abstract
INTRODUCTION AND IMPORTANCE Solitary bone plasmacytoma (SBP) is an early-stage plasma cell malignancy. It is an extremely rare condition and its diagnosis may not be straightforward. This report presents a case of maxillary SBP. CASE PRESENTATION A 48-year old man sought care for persistent swelling and pain in the periapical region of the left maxillary molars. He had been diagnosed with "apical periodontitis" and root canal treatment of teeth #26 and #27 was ineffective. Extra-oral examination revealed swelling at the left maxilla. Intraoral examination revealed a hard, non-fluctuant swollen region in the buccal alveolar mucosa adjacent to the apices of teeth #25-27. Cone-beam computed tomography revealed extensive bone destruction in the left maxilla. The patient underwent partial maxillary resection and radical maxillary sinusotomy. Further testing (positron emission CT scan, histopathological and immunohistochemical examination) confirmed the diagnosis of SBP. The patient had a recurrence two years later, which was managed with left subtotal maxillectomy and radiotherapy. There was no evidence of recurrence during 20 months of follow-up. DISCUSSION SBP may mimic an odontogenic lesion when found in the jaw bone. To confirm the diagnosis, routine blood test, complete body skeletal survey, metastatic investigations and histopathology should be performed. Radiotherapy is the primary treatment. CONCLUSION SBP may occur in the maxilla mimicking an odontogenic lesion. Surgery may be part of the diagnostic procedure and an adjunct to definitive radiation. Radiotherapy is the primary treatment.

Abstract
PURPOSE Rapid maxillary expansion (RME) is a routine method for correcting transverse maxillary deficiency. This paper investigated the effect of RME on anchorage alveolar bone and examined the differences between micro-implant-assisted RME and conventional RME. METHODS Relevant articles were selected from the PubMed, EMBASE and Cochrane Central Register of Controlled Trials databases. Review Manager software (v.5.3) was used for the pooled analysis and Cochran Q and I2 statistic tests were used to assess the heterogeneity. RESULTS Following conventional RME, the distal buccal alveolar bone thickness and the mesiobuccal alveolar thickness of the maxillary first molars were significantly reduced. Hyrax (standard mean difference [SMD]: -0.93, 95% confidence interval [CI]: -1.20-0.66) and Haas procedures (SMD: -0.88, 95% CI: -1.40-0.36) significantly reduced the buccal vertical alveolar height of the maxillary first molars. Similar results were obtained for the maxillary first premolars following RME. The thickness of the buccal alveolar bone decreased with conventional RME compared to when using the method assisted by micro-implants. CONCLUSIONS Conventional RME can reduce the thickness and vertical height of maxillary alveolar bone, and there is less loss of alveolar bone when using micro-implant-assisted RME. Further research is needed to validate the findings.

Abstract
AIM To review published cases and case series of the peripheral odontogenic keratocyst (POKC) of the gingiva, report an unusual presentation, and discuss lesional recurrence. MATERIALS AND METHODS A search of the English language literature for gingival OKCs was conducted. The inclusion of new case yielded a database containing 29 affected patients. Clinical, surgical, radiographic, and histopathologic findings have been summarized. RESULTS With available patient demographics, 62.5% were female and 37.5% were male, with an overall mean age at diagnosis of 53.8 years. There was near-equal lesional affinity for the jaws, of which 44.0% occurred in the posterior region, 32.0% anteriorly, and 24.0% overlapped these areas. Twenty-five percent of lesions had a normal color, 30.0% appeared yellow, 20.0% were white, and 10.0% were blue. The majority of lesions were < 1 cm and nearly 42% manifested exudation or fluctuance. Lesional pain was infrequent. Pressure resorption was recorded in 45.8% of cases. Most lesions were managed with conservative surgical modalities. Follow-up information was available in 16 primary cases, of which 5 recurred, signifying a 31.3% recurrence rate, including the featured case, which recurred twice. CONCLUSION To reduce recurrence of a gingival OKC, supraperiosteal dissection is advocated. Further, it is advised to follow POKCs for 5-7 years postoperatively, remaining vigilant for subtle clinical manifestations of recurrence. Timely discovery and excision of a POKC of the gingiva may decrease the incidence of a mucogingival defect.

Abstract
Both clear cell odontogenic carcinoma (CCOC) and sclerosing odontogenic carcinoma (SOC) are rare odontogenic malignancies. Here, we report a case of maxillary CCOC whose clinical and histologic features resembled those of SOC. Radiologically, the tumor presented as an ill-defined, expansile radiolucency with local bone destruction. Histologically, the tumor was comprised of thin cords or strands of odontogenic epithelium permeating through a sclerosed fibrous stroma with occasional clear cell foci. It damaged the cortical plates and invaded the adjacent soft tissue. Immunohistochemical expression of Pancytokeratin, Cytokeratin 19, p63, Cytokeratin 5/6, and Cytokeratin 14, as well as focal expression of Cytokeratin 7, demonstrated the epithelial nature of the tumor. Alcian Blue Periodic acid Schiff staining revealed a lack of intracellular mucin. Fluorescence in situ hybridization analysis revealed Ewing sarcoma RNA binding protein 1 and activating transcription factor 1 gene translocation, further confirming the diagnosis of CCOC. Lastly, we contextualized the genetic analysis of our case to that of CCOC in the literature.

Abstract
The recommended treatment strategy for stage 3 bisphosphonate-related osteonecrosis of the jaw (BRONJ) is currently rigid plate fixation without bone reconstruction. However, a recent systematic review indicated the utility of microsurgical reconstruction after resection of BRONJ. Several types of flaps have been described but their applications are controversial. Here we present a detailed reconstruction plan for obtaining better outcomes in patients with maxillary and mandibular BRONJ. Given that progressive maxillary BRONJ is often invasive to the skin, including the eyelid, leading to functional loss such as leakage of discharge and ectropion, several revision surgeries are needed to increase the volume in the defect after the free flap transfer. For progressive mandibular BRONJ, hemi-mandibulectomy to subtotal mandibulectomy with an adequate margin from the necrotic bone is necessary, followed by a well-designed fibular free flap.

Abstract
Smile design is defined as the process of creating an esthetic smile based on scientific and artistic guidelines established through studies, perception, and cultural and racial standards that have been recognized over time. Smile design is a dynamic field with evolving trends that take into consideration: facial esthetics, lip dynamics, pink and white esthetics, and personality. Traditional smile design focused on the orodental complex. Modern smile designers must have a global understanding of the entire patient to design the perfect smile.

Abstract
Background Trans-crestal sinus lift procedures are well established. Purpose to retrospectively analyse the efficacy of a flapless trans-crestal maxillary sinus floor elevation and simultaneous dental implant placement based on the Localised Management of Sinus Floor (LMSF) technique suitable for cases with sufficient width of keratinized tissue and of crestal bone but insufficient vertical dimensions of the bone below the sinus. Materials and methods 71 sinus elevations with simultaneous implant placement were performed on 52 consecutive patients. Following an initial pilot bur transmucosal perforation, the Magnetic Mallet was used with progressively larger osteotomes. The mallet osteotomes are initially directed palatally, towards the cortex of the medial wall of the sinus, below the palato-nasal recess (PNR) and then redirected in a more vertical direction to create the final osteotomy for implant placement. Results No significant complications were reported in the post-operative phase. The cumulative success rate during the observation period was 95%. All successful implants were successfully loaded with metal-ceramic or monolithic zirconia crowns and bridges and remained in function during the observation period. Conclusions Flapless Localised Management of Sinus Floor (LMSF) is a safe and effective surgical technique with minimal risks and with the advantage of low morbidity. Also, only native bone is used for augmentation and there is no need for additional grafting.

Abstract
Background and objective Sinus surgery has seen significant changes over the years with advancements in instruments, endoscopes and imaging. This study aimed to use Hospital Episode Statistics (HES) data to review the total number of sinus related procedures performed in both adults and children across England and identify whether there were any trends across the study period. We predicted an increase in endoscopic sinus procedures with a decline in open approaches to the paranasal sinuses. Methods Data from HES was extracted for the years 2010–2019. The operative (OPCS-4) codes relevant to all sinus procedures between E12.1 and E17.9 were analysed. After examination of overall sinus related procedures, further subgroup analysis was performed with regards to open or endoscopic techniques. Results The total number of sinus procedures performed between 2010 and 2019 was 89,495. There was an increase in endoscopic surgeries by 21.1% and a decrease of open surgeries 35.3% during this time. There was an overall increase in maxillary, frontal and sphenoid sinus procedures, with a decrease in ethmoid sinus and lateral rhinotomy operations. There was an increase in the proportion of endoscopic cases overall by 5.7% and for all sinuses individually. Conclusion Overall, we see an increase in sinus surgery over the last 9 years from 2010 to 2019. These findings are in keeping with our initial hypotheses. Although our data set is limited by coding, and lack of patient factors, it represents most, if not all, of the data in England over a large study period. It is therefore useful to add to previous studies when demonstrating the increasing popularity of endoscopic sinus surgery over open procedures.

Abstract
INTRODUCTION Synovial sarcoma is a malignant tumour of mesenchymal origin with an aggressive character and a rare cervicofacial location. Its management is multidisciplinary in order to improve prognosis and survival. CASE REPORT We report the case of two rare and synchronous localizations of monophasic synovial sarcoma of the maxilla and chest wall in a 58-year-old woman, whose management was based on exclusive chemotherapy. DISCUSSION The cervicofacial location of synovial sarcoma represents 3% of all locations in the body. Its clinical and radiological manifestations are aspecific. Its diagnosis is based on a combination of histological and genetic arguments. Its therapeutic management depends on the tumour stage and prognostic factors. CONCLUSION Early diagnosis of cervicofacial synovial sarcoma allows to avoid a mutilating procedure for the patient and to improve the long-term prognosis by a good control of the tumour.

Abstract
INTRODUCTION Chronic sinusitis can be considered a relative contraindication for sinus lifting procedure. However, its specific effects on bone height, infection and healing have not been as well investigated as its incidence as a post-operative complication. METHODS A retrospective comparative investigation was executed to evaluate the impact of chronic sinusitis on sinus lifting procedures regarding bone height, infection, and healing scores. Pre-operative and 6-month postoperative records (CBCT or CT and panoramic radiographs) of 40 patients who underwent sinus lifting procedure with graft and implant placement were split into two sets of 20 patients each; Group A is comprised of a patient with healthy sinus, whereas Group B includes patients with chronic sinusitis (identified as the presence of thickening of Schniederian membrane ≥ 2 mm, mucosal cyst, polyp or fluid level). Records of both groups were assessed for the difference in bone height of alveolar ridge between pre-operative radiograph and after six months postoperatively, and clinical notifications at the postoperative follow-up to report the healing and infection scores. RESULTS Statistically, there was non-significant difference in mean bone height gain (p-value > 0.05) in comparison to control group mean bone height (8.84 ± 0.93). Also, there was non-significant variation in mean healing and infection scores. CONCLUSION According to the available data, chronic sinusitis presenting as a thickening in the Schneiderian membrane has no significant effect on postoperative bone height, healing, or infection score in patients undergoing sinus augmentation with simultaneous implant placement. Further research is needed to better evaluate the effect of chronic sinusitis and its current status as a relative contraindication for sinus lifting procedure.

Abstract
Some young patients with a significant skeletal shift with a strong morpho-aesthetic and psychological impact may require surgical correction during their growth. A good understanding of facial growth, the different treatment options and the effects of surgery on the post-operative growth pattern will allow the practitioner to use the technique most suited to each of his patients and improve long-term treatment outcomes. So-called « interceptive » surgery may therefore be considered in cases of severe skeletal dysmorphism of secondary or functional origin. It will lead to early normalization with the immediate consequence of breaking the « dysmorpho-dysfunctional » spiral.

Abstract
BACKGROUND Surgical mobilization of the maxillary segment affects nasal morphology. This study assessed the impact of the type of maxillary mobilization on the three-dimensional (3D) nasal morphometry. METHODS Pre- and postsurgery cone beam computed tomography-derived facial image datasets of consecutive patients who underwent two-jaw orthognathic surgery were reviewed. Using preoperative 3D facial models as the positional reference of the skeletal framework, 12-month postoperative 3D facial models were classified into four types of maxillary mobilizations (advancement [n = 83], setback [n = 24], intrusion [n = 55], and extrusion [n = 52]) and four types of final maxillary positions (anterosuperior [n = 44], anteroinferior [n = 39], posterosuperior [n = 11], and posteroinferior [n = 13]). Six 3D soft tissue nasal morphometric parameters were measured, with excellent intra- and interexaminer reliability scores (ICC>0.897) for all the measurements. The 3D nasal change for each nasal parameter was computed as the difference between postoperative and preoperative measurement values. RESULTS The intrusion maxillary mobilization resulted in a significantly (all p<0.05) larger 3D nasal change in terms of alar width, alar base width, and nostril angle parameters, and a smaller change in terms of the nasal tip height parameter than the extrusion maxillary mobilization; however, no significant (all p>0.05) difference was observed between advancement and setback maxillary mobilizations. The anterosuperior and posterosuperior maxillary positions had a significantly (all p<0.05) larger 3D nasal change in terms of the alar base width and nostril angle than the anteroinferior and posteroinferior maxillary positions. CONCLUSION The type of maxillary mobilization affects the 3D nasal morphometry.

Abstract
Ectopic maxillary third molars (EMTM) are extracted mainly by the Caldwell-Luc technique but also by nasal endoscopy. There is currently no consensus on the treatment of this eruption and its management is heterogeneous and multidisciplinary. Two literature searches were performed with no time restrictions via Pubmed. In the first, we used the keywords "ectopic AND third molar" and in the second the keywords "dentigerous cyst AND ectopic third molar". For both articles, epidemiological, symptomatic, radiological and surgical data were recorded. Overall, 33 eligible articles were identified involving 39 cases of EMTM. 79% of patients were symptomatic. 87% of the teeth were associated with a dental cyst. In only 13% of cases was the location of the tooth in the sinus specified in the three planes of the space. Surgery was performed in 77% of patients by the Caldwell-Luc technique, by nasal endoscopy in 10% and by the Le Fort I approach in 3%. The indications for avulsion of EMTM are symptomatic patients or asymptomatic patients with an associated cyst. The intra-sinusal location of the tooth is not a factor in the choice of technique used, which depends rather on the individual skills of the surgeon. Although for a trained operator the Le Fort I osteotomy is an easy procedure, its interest in the treatment of EMTM is limited owing to the rare but potentially severe complications involved.

Abstract
Cemento-osseous dysplasia is a benign lesion which affects the jaw bones. It is a frequent incidental finding but no aggressive therapy is necessary. However, it may be confused with more aggressive entities, such as ossifying and cementifying fibroma, which do require treatment. There are no clear-cut histopathological criteria to differentiate between these entities. We present a case of a 13-year old boy who underwent a biopsy of a clinically undiagnosed maxillary lesion. Histopathological analysis revealed moderately cellular fibrous tissue with bone trabeculae with no osteoblastic rimming and clusters of intensely basophilic material corresponding to cementum. The final diagnosis was cemento-osseus dysplasia. The main histopathological features important in the distinction of these entities are discussed.

Abstract
This report describes an outbreak of purulent mandibular and/or maxillary osteomyelitis caused by Pseudomonas aeruginosa in a sheep flock located in the Khuzestan province, Iran. Jaw bones of almost 100 out of 500 mature sheep in a flock became severely deformed with a variably sized firm swelling, without any signs of inflammation in the surrounding soft tissues. The affected animals showed anorexia, depression, swelling of the mandibular and/or maxillary area, loss of cheek teeth and poor body condition. These animals were gradually culled in a period of 3 months. Postmortem examination showed a hard swelling of jaw bones with dirty greenish pus that filled alveolar molar teeth cavities. Histopathologic findings revealed necrotic areas surrounded by mixed population of inflammatory cells with exuberant fibrosis around some area of the lesions and irregular trabeculae of woven bone. In bacteriology, pure culture of P. aeruginosa was isolated from all of 7 sampled sheep. Based on clinical examination, radiography, histopathological features and bacteriology, the lesions were diagnosed as chronic suppurative osteomyelitis caused by P. aeruginosa. According to bacteriological results, the likely source of bacterial infection in this study was drinking water.

Abstract
OBJECTIVES This study sought to assess the efficacy of modified pedicle grafting as a noninvasive technique for soft tissue augmentation around maxillary dental implants. MATERIALS AND METHODS This descriptive study was conducted on eight patients who met the inclusion criteria. Prior to the second-stage surgery for exposing the implants, the buccal keratinized mucosa width, vestibular depth, and mucosal thickness around the implants were measured. The same parameters were measured six months after the second-stage surgery and were compared with the baseline values. Also, the color match of the graft with the adjacent gingival and mucosal tissues was evaluated. RESULTS Forty-seven maxillary implants were evaluated. The minimum and maximum gains of keratinized mucosal width were respectively equal to 0mm and 7mm, with a mean of 4.31±1.19mm. The mean vestibular depth around the implants was 9.47±1.75mm (ranging from 5mm to 12mm) six months after the surgery. At the beginning of the study, a thin mucosa surrounded the implants, but after six months, the peri-implant keratinized mucosa width increased. The color match of the graft with the adjacent gingival and mucosal tissues was excellent based on the periodontists' opinion. CONCLUSIONS Modified pedicle grafting is a safe and predictable technique for soft tissue augmentation around maxillary implants. This technique is reliable for increasing the width of keratinized mucosa in fully and partially edentulous patients with a shallow vestibular depth. The stability of the pedicle flap is achieved by fixing the flap to the tissue around the healing abutment.

Abstract
Sex estimation is one of the crucial procedures in the biological profile identification of human skeletal remains. Knowing sex of unknown case can lead to accurate and appropriate methods for predicting age, stature, ancestry, or even personal identification. Skull is one of the most reliable one among other skeletons and it is usually retained for both archaeological and forensic contexts. Although many morphological features and metric measurements of skull have been studied for sexing, but to the best of our knowledge is no study on maxillary suture length for sex estimation. Therefore, this study aims to develop a new sex estimation method for a Thai population by determining three maxillary suture lengths: anterior, transverse, and posterior maxillary suture, by computerizing amount of pixel obtained from photographs of these sutures. The present study was conducted on 190 Thai bone samples of which 96 were males and 94 were females. Independent t test revealed statistically significant difference (P<0.01) between males and females in all maxillary suture measurements. Equations derived from prediction model, which required three maxillary suture lengths gave 76.8421% accuracy from the leave-one-out cross validation in estimating sex percentage accuracies in predicting sex from these equations, which were relatively moderate. This study provides a novel and objective sex estimation method for Thais. It suggests that maxillary suture length can be applied for sex estimation. The new computerized technique will contribute basis knowledge and method for sex estimation, especially when only base of skull is available in forensic circumstance.

Abstract
Among the classification of maxillary fracture, the Le Fort classification is the best-known categorization. Le Fort (1901) completed experiments that determined the maxilla areas of structural weakness which he designated as the “lines of weakness”. According to these results, there are three basic fracture line patterns (transverse, pyramidal and craniofacial disjunction). A transverse fracture is a Le Fort I fracture that is above the level of the apices of the maxillary teeth section, including the entire alveolar process of the maxilla, vault of the palate and inferior ends of the pterygoid processes in a single block from the upper craniofacial skeleton. Le Fort fractures result in both a cosmetic and a functional deficit if treated inappropriately. In this article, authors review the management of a Le Fort I fracture with a case-based discussion.

Abstract
Arteries that supply the nasal septum and the lateral nasal wall include vessels that originate from the external carotid artery and from the internal carotid artery. A variety of local endonasal pedicle flaps can be used in different anatomical areas for endoscopic skull base reconstruction. The main flaps are based on terminal branches of the sphenopalatine artery and on anterior ethmoidal artery. This study will describe the anatomy of these vessels and their relationship with the main flaps.

Abstract
INTRODUCTION Multidetector Computed Tomography (MDCT) is a widespread method for evaluating paranasal sinuses and nasal cavity in daily practice. The maxillary teeth are in field of view in a paranasal sinus CT scan and it is possible to detect dental pathologies with CT. AIM To determine the incidence of maxillary teeth pathologies in routine paranasal sinus CT scans. MATERIALS AND METHODS A retrospective study was conducted. Consecutive 395 paranasal sinus CT scans were evaluated. All CT images were obtained with a 64 detector-CT. Patients with previous facial trauma, operation, invasive tumors and repeated exams were excluded. Detected findings were classified as "tooth loss, dental restorations or procedures and dental pathologies (carious lesions, dental developmental anomalies, periapical lesions and periodontal diseases). The proportion of findings was reported as simple percentiles. RESULTS Three hundred and eighty-four CT scans were included in the study. Dental restorations or procedures were determined in 129 (33.5%) patients. A total of 34 (8.8%) patients had normal teeth count and morphology. A total of 264 (64.3%) patients had at least one tooth loss. A total of 195 (51%) patients had at least one or more dental pathology. Number of dental carious lesions, dental developmental anomalies, periapical lesions and periodontal disease were 104 (27.0%), 78 (14.3%), 46 (11.9%), 44 (11.4%), respectively. CONCLUSION Dental pathologies were encountered in more than half of the patients. Detecting dental pathologies may prevent tooth loss and improve oral health. The radiologist should keep in mind dental pathologies while evaluating paranasal sinus CT in daily practice.

Abstract
OBJECTIVE Unilateral sphenoid sinus opacification (SSO) on imaging is a common incidental radiologic finding. Inflammatory sinus disease is rarely isolated to one sinus cavity therefore SSO raises the potential for neoplastic etiology. The clinical significance of SSO was evaluated and compared to maxillary sinus opacification (MSO). METHODS A systematic review of unilateral sinus opacification was performed via Medline (1966-January 12th, 2015) and Embase (1980-January 12th, 2015), limited to English literature and human subjects. Case series of patients treated with radiologic evidence of unilateral sinus opacification either from maxillary or sphenoid sinuses and with pathology results were included. Individual cases were classified as neoplastic, malignant, or a condition requiring surgical intervention (i.e. fungal ball). Exclusion criteria were single case reports, lack of primary data, series of complications, or single pathology series. Case-by-case analysis was performed for both SSO and MSO. RESULTS Search strategy revealed 3264 studies. A total of 31 studies including 1581 patients met the inclusion criteria. In these studies, SSO was described in n=1215 (76.9%) and MSO in n=366 (23.1%). For SSO, the final diagnosis was neoplasia 18%, (malignancy in 10.9%). 58.3% of cases required surgical intervention and 13% were inflammatory. For MSO, neoplasia represented 18.3% (malignancy 7.1%), surgical intervention required in 47% of cases and 27.6%. were inflammatory. CONCLUSION Isolated MSO and SSO is a marker of neoplasia in 18% and malignancy in 7-10% of patients presenting with these radiologic findings. Clinicians should be wary of conservative management given the high incidence of neoplasia and consider a lower threshold for early surgical intervention.

Abstract
BACKGROUND Supplemental teeth refer to extra teeth that resemble the normal tooth series. Bilateral supplemental central incisors in a healthy individual are rare and bilateral supplemental incisors with double-tooth like appearance are exceptionally rare and has not been previously reported in the dental literature. CASE REPORT This clinical report describes an 8-year old healthy Indian boy referred for the management of delayed eruption of his permanent maxillary incisor teeth. Following clinical and radiographic examination the two supplemental incisors closer to the midline were extracted under local analgesia and both of them exhibited double-tooth like appearance. CONCLUSIONS The present case refutes the conventional wisdom that "supplemental teeth are usually smaller than the normal tooth type they resemble and occur distal to the normal tooth series", illustrates that the unusual can occur and that the clinician should be aware of such variations.

Abstract
INTRODUCTION Schwannomas are benign tumours that are relatively common in the head, however the involvement of the sinunasal region is rare and there are only 5 cases reported in the maxilla in current literature, representing less than 1% of bone tumours. CLINICAL CASE We report the case of a woman with a right maxillary schwannoma who underwent a complete resection of the lesion. Emphasis is placed on the rarity of the lesion in terms of its location and includes a review of clinical behaviour, diagnosis and current treatment options. CONCLUSIONS Maxillary trigeminal schwannoma must be suspected if vague sinunasal symptoms, paranasal mass or, as in this case, trigeminal neuralgia present. Surgical treatment is indicated, and approaches vary according to location and tumour size.

Abstract
INTRODUCTION Beta thalassemia is a blood dyscrasia that caused a marked expansion of active marrow spaces and extramedullary haematopoiesis results. In these patients various alterations and abnormalities affects different body areas, including increased risk of sinusitis. The marrow expansion in the facial bones results in delay in pneumatisation of the sinuses, overgrowth of the maxillae, and forward displacement of the upper incisors with skeletal deformities. In current literature, maxillary sinuses are not deeply evaluated by CT scan studies in these kind of patients. The aim of our study was to investigate the presence of maxillary sinuses abnormalities by the use of CT in patients with beta-thalassemia major and to compare these findings with a control group free from this disease. MATERIALS AND METHODS A retrospective analysis of 22 paediatric patients with beta-thalassemia major and 22 control subjects without sinonasal diseases was performed. CT was done using a 64-multidetector-row CT scanner without contrast injection, obtained in axial plane using thin-slice technique. Evaluated parameters were: bone thickness of the lateral and anterior wall, density and volume of the maxillary sinuses. RESULTS Significant difference was found between the study group and control group in the evaluation of all the parameters examined. The maxillary sinus of β thalassemic patients was smaller respect of controls, the bone was more dense and thick in the side and anterior wall. Beta-thalassemic patients have a relative risk of 2.87 to develop a maxillary sinusitis. DISCUSSION In these patients there is an increased incidence of sinonasal infections due to the abnormal development of cranio facial skeleton. These bone alterations might confuse the physicians and lead to an increased rate of sinusitis diagnoses.

Abstract
Background: Increasing sinus pneumatization and the accompanying alveolar bone resorption complicate dental implant placement. This problem can be overcome today by raising the maxillary sinus floor with graft materials. Bisphosphonates are commonly used to accelerate the recovery of the graft materials and to prevent resorption. Objectives: The purpose of this study is to investigate whether systemic administration of a bisphosphonate (alendronate) would improve new bone formation and reduce fibrous tissue formation over a 6-week follow-up in rabbits treated with two different grafting materials for maxillary sinus floor augmentation. Materials and Methods: This experimental animal study was conducted at the Experimental Medical Application and Research Center at Erzurum/ Turkey. Twelve New Zealand rabbits, each weighing between 2.7 and 3.3 kg, were used. Twenty-four maxillary sinus floor elevation operations were performed, two on each animal (n = 24). Each elevation was repaired with either deproteinized bovine bone (xenograft) or autogenous bone graft obtained from the iliac crest. Both groups were divided into 2 subgroups: saline-treated and alendronate-treated. All groups underwent the same surgical procedures and evaluation, and were sacrificed at the 6th postoperative week. Sinuses augmented with deproteinized bovine bone (xenograft) and autogenous bone graft were examined histopathologically and histomorphometrically. Results: At 6 weeks, the bone area was significantly larger in the Xenograft-Alendronate group (33.0% ± 5.0%) than in the Xenograft-Saline group (20.8% ± 4.9%) and the bone area was significantly larger in the Autogenous-Alendronate group (43.3% ± 3.8%) than in the Autogenous-Saline group (37.5% ± 6.6%) (P = 0.001). The histomorphometric and histopathological results consistently showed that alendronate stimulated bone formation and reduced fibrous tissue formation in maxillary sinus augmentation grafts, especially in the deproteinized bovine bone group (xenograft). Conclusions: Alendronate may be considered a therapeutic option for improving the bone formation process and reducing resorption in different bone grafting procedures. Further detailed studies should focus on dosage and time-dependent effects of alendronate on bone remodeling.

Abstract
The expression and regulation of Hox genes in developing central nervous system (CNS) lack important details like specific cell types where Hox genes are expressed and the transcriptional regulatory players involved in these cells. In this study we have investigated the expression and regulation of Drosophila Hox gene Deformed (Dfd) in specific cell types of embryonic CNS. Using Dfd neural autoregulatory enhancer we find that Dfd autoregulates itself in cells of mandibular neuromere. We have also investigated the role of a Hox cofactor Homothorax (Hth) for its role in regulating Dfd expression in CNS. We find that Hth exhibits a region specific role in controlling the expression of Dfd, but has no direct role in mandibular Dfd neural autoregulatory circuit. Our results also suggest that homeodomain of Hth is not required for regulating Dfd expression in embryonic CNS.

Abstract
Hox genes are highly conserved selector genes controlling tissue identity and organogenesis. Recent work indicates that Hox genes also controls cell segregation and segmental boundary in various species, however the underlying cellular mechanisms involved in this function are poorly understood. In Drosophila melanogaster, the Hox gene Deformed (Dfd) is required for specification and organogenesis of the adult Maxillary (Mx) palp. Here, we demonstrate that differential Dfd expression control Mx morphogenesis through the formation of a physical boundary separating the Mx field and the Peripodial Epithelium (PE). We show that this boundary relies on DE-cadherin (DE-cad) basal accumulation in Mx cells controlled by differential Dfd expression. Indeed, Dfd controls boundary formation through cell autonomous basal redistribution of DE-cad which leads to subsequent fold at the Dfd expression border. Finally, the loss of Mx DE-cad basal accumulation and hence of Mx-PE folding is sufficient to prevent Mx organogenesis thus revealing the crucial role of boundaries in organ differentiation. Altogether, these results reveal that Hox coordination of tissue morphogenesis relies on boundary fold formation through the modulation of DE-cad positioning.

Abstract
OBJECTIVES The aim of this study was to investigate the displacement and stress distribution during surgically assisted rapid maxillary expansion under different surgical conditions with tooth- and bone-borne devices. MATERIALS AND METHODS Three-dimensional (3D) finite element model of a maxilla was constructed and an expansion force of 100 N was applied to the left and right molars and premolars with tooth-borne devices and the left and right of mid-palatal sutures at the first molar level with bone-borne devices. Five computer-aided design (CAD) models were simulated as follows and surgical procedures were used: G1: control group (without surgery); G2: Le Fort I osteotomy; G3: Le Fort I osteotomy and para-median osteotomy; G4: Le Fort I osteotomy and pterygomaxillary separation; and G5: Le Fort I osteotomy, para-median osteotomy, and pterygomaxillary separation. RESULTS Maxillary displacement showed a gradual increase from G1 to G5 in all three planes of space, indicating that Le Fort I osteotomy combined with para-median osteotomy and pterygomaxillary separation produced the greatest displacement of the maxilla with both bone- and tooth-borne devices. Surgical relief and bone-borne devices resulted in significantly reduced stress on anchored teeth. CONCLUSION Combination of Le Fort I and para-median osteotomy with pterygomaxillary separation seems to be an effective procedure for increasing maxillary expansion, and excessive stress side effects are lowered around the anchored teeth with the use of bone-borne devices.

Abstract
Maxillary sinus expansion and atrophy can be difficult to overcome for patients who require functional dental prostheses. One solution for this problem is sinus augmentation and implant placement. Patients are evaluated and diagnosis is ascertained, leading to development of a treatment plan and surgical strategy. The surgeon decides on a surgical technique and grafting material, based on ultimate success, stability, and function as they relate to the goals. Complications can occur during an operation or during the postoperative healing phase. Dealing with these complications can be challenging; however, solving these problems positively affects the overall outcome and success.

Abstract
INTRODUCTION Intraoral neurilemmomas (schwannoma) are rare, even rarer are intraosseous ones, and the rarest are the maxillary neurilemmomas. Going by the literature only 5 cases of maxillary neurilemomas are reported till now. Neurilemmomas are benign tumours of nerve sheath origin. Approximately 30% arise in head and neck region, of these 1–12% arise intraorally mainly involving tongue. PRESENTATION OF CASE Here we report two cases of maxillary neurilemmoma, one in a 9 year old girl and second one in a 27 year old female, both involving the lateral surface of maxilla on right side. Both the patients presented with a long standing history of swelling which was increasing gradually. 9-Year-old girl also had 1 lesion in the temporal region on right side and the 27-year-old patient had associated erosion of the soft palate. Diagnosis was made on the basis of histopathology and immunohistochemistry. DISCUSSION Neurilemmomas are slow growing benign tumour of the nerve sheath origin arising from the Schwann cells. Their aetiology is not known. Most common complaint is that of a gradually increasing swelling followed by pain and paresthesias. Surgery remains the treatment of choice with close follow up. CONCLUSION Maxillary neurilemmomas are rarest of the rare tumour which closely mimic benign odontogenic cysts and tumours, and should be kept in the differential diagnosis of these lesions. Knowledge of the radiologic and clinical behaviour of these tumours is extremely important for prompt diagnosis and treatment.

Abstract
The purpose of the study was to determine the mesiodistal width of six anterior teeth for better esthetics and good tooth arrangement in a cross section of Rajasthan population. The mesiodistal dimension of central, lateral incisor and canine on right and left sides was measured in 250 males and 250 females, these readings were used to determine the mean, minimum and maximum maxillary/mandibular teeth 'anterior ratio', difference in mesiodistal width, combined mean mesiodistal width, the number and percent of similar teeth of maxilla and mandible. It was observed from the present study that there is variation in mesiodistal width in right and left sides signifying that the anterior teeth are not mirror images of one another. Male subjects have greater mesiodistal width than female subjects and right side dominates in most of the readings indicating that mesiodistal width is greater on right side than on left side. Percentage variability and sexual dimorphism are also important findings of this study. This study can prove helpful in replacement of artificial teeth of prosthesis in this cross section of population.

Abstract
BACKGROUND Five-year survival in squamous cell carcinoma of maxillary antrum is low. This article examines the results of various approaches to treatment as given in our hospital in past 26 years. METHODS From 1979 to 2005, 379 patients with squamous cell carcinoma of maxillary antrum managed with curative intent were studied. Twenty-eight patients had T2, 237 patients had T3, and 114 had T4 tumors. The N classification was N0 in 316 patients, N1 in 21 patients, N2a in 28 patients and N2b in 14 patients. Treatment to the primary site comprised of surgery (Sx) and radiation therapy (RT) in 284 patients, RT alone in 57 patients and chemotherapy (CTx) with radiotherapy in 38 patients. RESULTS There was a difference in survival between patients who underwent Sx with RT compared with patients who received RT alone or CTx with RT. The most common pattern of recurrence was in the primary site, 187 (49.3%) patients. Local control at 3 and 5 years was 71% and 63.8% respectively in Sx with RT, 31.6% and 28% respectively in RT, and 28.9% and 26% in CTx with RT group. CONCLUSIONS The type of treatment to the primary site is an important determinant of survival and local control. Surgery with radiation is a better treatment option.

Abstract
UNLABELLED The aim of this case report was to describe the clinical management of an unusual dens invaginatus type 3. A case of dens invaginatus in a maxillary lateral incisor with a periapical lesion is reported. The patient presented with pain and localized swelling. Despite the complex anatomy and diagnosis of dens invaginatus, non-surgical root canal treatment was performed successfully. KEY LEARNING POINTS - Dens invaginatus may be presented in different forms, and the etiology of this phenomenon is not fully understood. - Due to abnormal anatomical configuration, dens invaginatus presents technical difficulties in its clinical management. - Non-surgical root canal treatment can be performed successfully.

Abstract
INTRODUCTION This article describes the diagnosis and treatment of two symmetrical maxillary first molars with two canals in their distobuccal roots. A 32-year-old female had an emergency treatment because of the pain in tooth #16. On the second visit after accessing the pulp chamber and detecting three major canals (MB, DB, and P) and exploring the 4th canal (MB2), we noted that there was a 5(th) canal in the distobuccal root. Also, necrosis was found in the same patient after examining the tooth #26 which was severely decayed. Then after preparing the access cavity, the same order of orifices was found in tooth #16. An electronic apex locator was utilized to ensure that a perforation of the pulpal floor had not occurred. Working films confirmed the presence of an additional canal in distobuccal root.
