The purpose of this article is to present the case of maxillofacial trauma patient with maxillary sinus fracture diagnosed with cone-beam computed tomography (CBCT) and to explore the applications of this technique in evaluating the maxillofacial region. A 23-year-old male patient attempted to our clinic who had an injury at midface with complaints of swelling, numbness. The patient was examined before in emergency center but any diagnosis was made about the maxillofacial trauma. The patient re-examined clinically and radiographically. A fracture on the frontal wall of maxillary sinus is determined with the aid of CBCT. The patient consulted with the department of maxillofacial surgery and it is decided that any surgical treatment was not necessary. The emerging technique CBCT would not be the primary choice of imaging maxillofacial trauma. Nevertheless, when advantages considered this imaging procedure could be the modality of choice according to the case.

BACKGROUND: Nowadays, cone beam computed tomography (CBCT) are commonly used in dentistry with an advantage about significantly lower dose comparing with CT-Scanner. Utilizing CBCT images which are indicated in dentistry like orthodontics can help diagnose diseases beyond dentistry field. One rare phenomenon can be seen in maxillary sinus, which is often overlooked by dentists, is ectopic teeth. CASE REPORT: This article describes one orthodontic case found accidentally an ectopic tooth in maxillary sinus by inspecting CBCT images. CONCLUSION: Dentists and oral radiologists should carefully inspect non-dental structures, like maxillary sinus, even its distance from the dentoalveolar region, especially in asymptomatic patients.

Introduction: Maxillofacial injuries are one of the most frequently encountered entities accounting for a large proportion of patients in emergency department. Present study was performed to assess the role of multidetector computed tomography (MDCT) in patients of maxillofacial trauma and to describe the spectrum of various patterns of injuries in maxillofacial region in this part of Nepal. Methods: The study was carried out on a prospective basis over a period of one year. All the patients referred for evaluation of maxillofacial trauma were included in the study. MDCT was done in patients of maxillofacial injury and the data was recorded and analyzed. Volumetric MDCT scan of the maxillofacial region was performed in axial plane with multiplanar reconstruction in coronal and sagittal planes were obtained wherever required. Results: Out of 60 patients of maxillofacial trauma 42 (70%) were males and 18 (30%) were females and age ranges from 12 to 70 years. The 11?30 years age group has the highest percentage (55%) of maxillofacial trauma, followed by 31?40 (20%). The common cause of injuries in our study was road traffic accidents (58.33%), fall from height (20%), physical assault (16.66%) and sport injuries (5%). Out of 60 patients there was total of 115 fractures. The frequency and types of fracture was as follows: orbital floor fracture in 21 (35%), maxillary sinus wall fracture in 18 (30%), nasal bone fracture in 17 (28.33%), jaw fracture in 15 (25%), zygomatic bone fracture in 13 (21.66%), orbital wall fracture in 11 (18.33%), naso?ethmoidal fractures in 9 (15%), frontal sinus fracture in 7 (11.66%), Lefort fracture in 1 (1.66%) and others 3 (5%). The highest percentage of fracture was of orbital floor (35%) followed by fracture of wall of maxillary sinus (30%) and nasal bone fracture (28.33%). Three cases had simultaneous injury of the globe and cervical spine; they underwent computed tomography/magnetic resonance imaging for the assessment of spine. Conclusion: Injuries to maxillofacial region is one of the most common emergency requiring accurate and early diagnosis for preventing unnecessary investigations and proper management. MDCT has high sensitivity and specificity and has high accuracy for detection of fracture. DOI: http://dx.doi.org/10.3126/ajms.v5i4.9561 Asian Journal of Medical Sciences 2014 Vol.5(4); 39-43

Pendahuluan: Tindakan implan merupakan salah satu upaya untuk mengganti gigi yang hilang. Pemasangan implan yang baik, mampu memberikan kenyamanan dan aspek estetis yang baik. Pemasangan implan yang penuh dengan resiko dan ketidak hati-hatian pada pemasangan berakibat tidak baik bagi pasien. Tujuan dari penulisan laporan kasus ini adalah untuk melaporkan kasus ketidaknyamanan yang disebabkan timbulnya reaksi inflamasi disertai supurasi pada sinus maksilaris paska pemasangan implan, dan juga untuk melihat kemampuan dari Cone Beam Computed Tomography (CBCT) dalam menganalisa hal tersebut. Laporan  kasus: Perempuan berusia 40 tahun, mengeluhkan adanya rasa tidak nyaman berupa bau mulut dan hidung disertai hidung tersumbat dan pusing kepala. Anamnesa diketahui bahwa pasien telah melakukan pemasangan implan 3 bulan sebelumnya. Pemeriksaan intraoral menemukan adanya implan pada regio posterior, tanpa rasa sakit dan tanda peradangan. Manajemen kasus dilakukan dengan meminta pasien melakukan pemeriksaan CBCT, karena dicurigai rasa tidak nyaman, pusing dan bau disebabkan oleh implan yang saat ini telah terpasang. Setelah dilakukan pemeriksaan CBCT ternyata ditemukan sinus aproksimasi pada ujung implan. Ujung implan masuk ke dalam sinus dengan panjang lebih dari 2 mm. Hal ini menyebabkan infeksi pada dinding sinus dan berkumpulnya nanah pada daerah sinus. Hal ini membuktikan bahwa implan menyebabkan infeksi pada sinus sehingga kasus ini terjadi. Pasien kemudian dirujuk ke bagian bedah untuk dilakukan perbaikan pada implan. Simpulan: Inflamasi sinus disertai supurasi pada sinus maksilaris paska pemasangan dapat terjadi, hal ini terjadi kemungkinan karena respon tubuh terhadap implan yang masuk ke rongga sinus. Analisa dapat dilakukan dengan memanfaatkan radiografi CBCT.Kata kunci: Implan, CBCT, infeksi sinus maksilaris. ABSTRACTIntroduction: Dental implant placement is an attempt to replace missing teeth. Installing the right implant can provide comfort and good aesthetic aspects. However, the installation of implants with full risks and caution will hurt the patient; thus proper planning is needed for implant placement. The purpose of this case report was to report cases of discomfort caused by an inflammatory reaction accompanied by suppuration in the maxillary sinus after implant placement and also to see the ability of Cone Beam Computed Tomography (CBCT) in analysing this. Case report: A 40-years-old woman complains of discomfort in the form of bad breath, nasal congestion, and headache. Anamnesa found that the patient had implant placement 3 months earlier. An intraoral examination found an implant in the posterior region, with no signs of pain and inflammation. Case management was performed by asking the patient to do a CBCT examination due to suspected discomfort, dizziness and bad breath caused by implants that are currently installed. After a CBCT examination found a sinus approximation at the tip of the implant. The tip of the implant goes into the sinus with a length of more than 2 mm. This caused an infection of the sinus wall and the gathering of pus in the sinus area. This proves that the implant caused an infection of the sinuses. The patient was then referred to the surgical section for the implant repairment. Conclusion: Sinus inflammation accompanied by suppuration of the maxillary sinus after installation can be occurred likely due to the body’s response towards the implants entering the sinus cavity. Analysis can be performed using CBCT radiography.Keywords: Implant, CBCT, maxillary sinus infection.

Abstract Background The proximity of the maxillary sinus floor to the maxillary molar roots increases the probability of oroantral communication on conducting any surgical or endodontic procedure in the involved area. The aim of this study is to evaluate the relationship between each maxillary molar root and maxillary sinus floor using cone beam computed tomography. Predicting the probability of protrusion of each root into the sinus will consequently predict the probability of occurrence of the oroantral fistula in a sample of the Egyptian population. Results The total number of roots located outside the sinus was 121 (35.3%), while those contacting the sinus floor were 80 (23.3%) and those intruded the sinus were 141 (41.2%). The percentage of root intrusion into the sinus in males (56.9%) was significantly (p = 0.01) higher than females (42.9%). The probability of root intrusion in the left molars (54.2%) was non-significantly (p = 0.067) higher than that of the right side (44.3%). As for the type of tooth, the second molar showed the highest probability of root intrusion into the sinus (55.3%) followed by the third molars (52.6%) then the first molars (40.9). According to the type of root, the mesiobuccal root showed the highest probability of intrusion into the sinus (50.9%) followed by the palatal root (49.1%) then the distobuccal root (47.4%). However, the difference in both type of tooth and type of root was statistically non-significant (p = 0.051 and 0.869 respectively). As for the individual root with the highest probability of intrusion, the mesio-buccal root of the right third molar is the most frequent root to intrude the sinus (71.4%) and the mesio-buccal root of the right first molar is the least frequent (22.7%). Conclusions In a sample of the Egyptian population, males exhibit higher probability of root protrusion into the sinus than females. The side and type of tooth are of higher impact on the probability of its intrusion into the sinus compared to the type of root. Left second molars are at a higher risk of oroantral communications on surgical or endodontic procedures compared to other molars due to its highest probability of intrusion into the sinus.

Relationship Of

Cone beam CT (CBCT) produces threedimensional information on the facial skeleton, teeth and their surrounding tissues; and is increasingly being used in many of the dental specialties. This is usually achieved with a substantially lower effective dose compared with conventional medical computed tomography (CT). Periapical pathologies, root fractures, root canal anatomy and the true nature of the alveolar bone topography around teeth may be assessed. CBCT scans are desirable to assess posterior teeth prior to periapical surgery, as the thickness of the cortical and cancellous bone can be accurately determined as can the inclination of roots in relation to the surrounding jaw. The relationship of anatomical structures such as the maxillary sinus and inferior dental nerve to the root apices may also be clearly visualized. Measurements on CBCT are more accurate when compared with OPG. Therefore, CBCT permits the clinician to have all necessary information when planning dental implants. The purpose of this article is to provide an overview of the unique image display capabilities of maxillofacial CBCT systems and to illustrate specific applications in clinical practice.
