The aim of this article is to describe a large mandibular cyst treated with decompression followed by surgical enucleation. Furthermore, we described the utility of cyst volume measurements by using a 3D reconstruction on Cone Beam Computed Tomography (CBCT). The dentigerous cyst is the most common cyst type of epithelial origin, arising from remnants of odontogenic epithelium, asymptomatic and associated with the crown of an unerupted or partially or completely impacted tooth. However, after a long duration and extension of the cyst volume it may provoke significant bone resorption, cortical expansion, tooth displacement and the vitality of neighboring teeth may be affected. The regular treatment of this lesion is enucleation and extraction of the involved tooth. Marsupialization and decompression are proposed when the volume of the cyst is well developed to release the cystic pressure and allow the bone cavity to progressively decrease in volume with the gradual apposition of bone. This report presents a large dentigerous cyst related to impacted mandibular third molar of a 21-year-old male patient. The cyst was treated successfully by decompression and later by surgical enucleation with surgical extraction of the related molar. In conclusion, the combination of decompression and surgical approach showed on the three-dimensional CBCT investigation a significant correlation between the treatment and volume reduction of the cyst. The clinical case described allows us to observe bone formation after decompression and surgical enucleation was performed with less risk on vital anatomic elements.

Introduction: Diagnosis and management of impacted mandibular third molars call for a cogent appraisal and treatment choice both for the sick person and the dental practitioner. This academic work scrutinized the pattern as well as treatment of impacted mandibular third molars at the Teem Clinic and Dental Centre, Ekpan, Delta State, in Nigeria.Materials and Methods: This cross-sectional survey involved 131 cases who reported impacted mandibular third molars. The age, gender, impacted tooth, type of impaction, pathological conditions, and treatment proffered were recorded.Results: The male to female ratio was 0.8:1, with an age range of 10 to 40 years. Of the lower third molar impactions 58 (42.0%) were mesioangular, 5 (3.6%) horizontal, 18 (13.0%) vertical and 57 (41.3%) were distoangular. A total of 47 (34.1%) quested for dental attention following varying degrees of pain induced by pericoronitis. Teeth removal was accomplished for 76 (55.0%) owing to carious lesions on the impacted teeth, proximate tooth, or both. Surgical extraction was the option taken in 69 (50.0 %) with caries on the impacted teeth while 3 (2.2%) had to pull out of their teeth done owing to carious lesions on the bordering second molars. In 3 (2.2%) both the impacted third molar and the proximate second molar were decayed. Conclusions: The prevailing indication for pulling out impacted mandibular third molars was acute pericoronitis. Mesioangular sort of impaction was most recurrent and ought to be considered for theplausibility of frequentness of complications.

Objectives: The aim of this report which contains three case series is to describe the radiographic characteristic of dentigerous cyst using CBCT. Case Report: In the case presented here, all of the three patients had dentigerous cyst developing in impacted tooth, but did not have the same symptoms. CBCT radiography examination was carried out to find out the margin of the cortical extension, the diameter of the lesion, and the relations between the lesion and adjacent structures. The result of CBCT examination shows there is a variation of radiograph characteristics of dentigerous cyst among the three patients. Conclusion: CBCT is a very useful complementary tool for diagnosis and surgical planning in cases of dentigerous cyst, because three-dimensional viewing of the structures offers greater accuracy in lesion identification.

AbstractThere have been infrequent case reports of bilateral root resorption in the lower second molar secondary from impacted third molar removal with bone regeneration without pain. Root resorption is commonly observed during third molar surgical impaction that affects mandibular second molars. The bone regeneration into the adjacent affected tooth is evident simply after the surgical extraction of the impacted tooth. However, there have been a few previous reports on the prognosis of the remaining resorbed tooth. Most dentists often choose to extract them when damaged if root resorption is observed. This report case involved bilateral root resorption of the lower second molar due to lower adjacent impacted third molar teeth and bone regeneration without pain sensation. After surgical extraction of bilateral lower impacted third molar teeth, the remaining teeth retained vital pulp and survived as functional teeth.

Objectives: To characterize the radiographic features of maxillary ameloblastoma (AM), odontogenic keratocyst (OKC) and dentigerous cyst (DC) comparatively by using spiral CT and cone beam CT (CBCT). Methods: Clinical records, histopathological reports, and nonenhanced spiral CT or CBCT images of 191 consecutive patients with primary maxillary AMs, OKCs, or DCs were retrospectively acquired, and radiographic features were analyzed. Results: The study included 118 males and 73 females (age: 5–84 years). 72.0% of AMs and 84.3% of OKCs originated from the posterior maxilla, while 69.6% of DCs occurred in the anterior maxilla. Among 25 AMs, 44.0% were of desmoplastic type, with honey-combed appearance. 84.0% of AMs were circular or oval in shape, 84.0% expanded buccally, and 36.0% invade the nasal floor. Among 89 OKCs of 88 patients, 61.8% were circular or oval, 58.4% expanded buccally, 49.4% were dentigerous, 41.6% nearly filled the maxillary sinus, and 13.5% invaded the nasal floor. 93.7% (74/79) of DCs enveloped a single tooth, and the tooth–cyst relationship was centripetal in 35, eccentric in 30, and circumferential in 9. Moreover, 98.2% (55/56) of the cysts enveloping a supernumerary tooth were DCs, while 80.9% (38/47) of the cysts enveloping the third molar were OKCs. Conclusions: Maxillary AMs tend to grow with buccal expansion and invade the nasal floor, and DAs with honey-combed lobularity are common. Maxillary OKCs have variant shapes and tend to invaginate the maxillary sinus. The tooth–cyst relationship of dentigerous OKCs and DCs can be centripetal, eccentric, or circumferential.

Gigi dikatakan impaksi ektopik apabila mengalami malposisi yang disebabkan oleh faktor kongenital atau mengalami perubahan posisi yang disertai dengan kondisi patologis. Kondisi patologis yang sering menyertai gigi impaksi ektopik adalah kista dentigerous. Tujuan dari studi pustaka ini adalah untuk memaparkan odontektomi pada kasus molar ketiga ektopik yangdisertai dengan kista dentigerous. Operasi ini adalah untuk menghilangkan faktor penyebab terjadinya kista dentigerous serta membersihkan lesi kista agar tidak berkembang semakin membesar. Pasien laki-laki 38 tahun mengeluhkan adanya sedikitbenjolan pada pipi sebelah kanan namun tanpa disertai rasa sakit. Benjolan dirasakan mulai muncul dalam satu tahun terakhir.Hasil pemeriksaan radiografik menunjukkan gigi molar ketiga mandibula kanan berada pada sudut angulus mandibula disertaiadanya gambaran radiolusen pada mahkotanya didiagnosa sebagai impaksi ektopik gigi molar ketiga mandibula kanan disertaikista dentigerous. Tindakan operasi odontektomi dan enukleasi kista dentigerous dilakukan secara ekstraoral dengananastesiumum, pemilihan metode pengambilan ekstraoral karena posisi gigi yang telah berubah jauh dari posisi normal gigimolar ketiga mandibula. Telah dilakukan pengambilan gigi molar ketiga mandibula yang impaksi ektopik dan enukleasi kistadentigerous secara ekstraoral, karena posisi gigi impaksi yang ektopik di ramus mandibula. Pengambilan gigi impaksi secaraekstraoral sangat jarang sekali dilakukan, namun jika posisi gigi berada jauh sekali dari posisi normal maka pendekatanekstraoral merupakan metode operasi yang akan mempermudah proses pengambilan gigi dan enukleasi kista serta dapatmeminimalkan hilangnya tulang mandibula yang sehat. ABSTRACT: Odontectomy of Ectopic Third Molar Associated with Dentigerous Cyst in Submandibular Region. Ectopic impacted tooth has been defined as malpositioned tooth caused by congenital factor or malpositioned tooth associated with pathologic condition. Pathologic condition associated with ectopic impacted tooth is dentigerous cyst. The purpose of this operation is to eliminate the causes of the dentigerous cyst and to raise cyst lesions that do not develop as they grow. A 38-year-old male patient complained of a painless slight swelling on his right cheek which occurred in the last one year. The radiograph examination shows an ectopic right mandibular third molar at the posterior border of the right angle of mandible, with an associated coronal radiolucency diagnosed as ectopic impacted right mandibular third molar associated with dentigerous cyst. The tooth and the cyst were removed surgically under general anesthetic via an extra-oral approach due to an extreme malposition of the tooth. The ectopic impacted right mandibular third molar and associated dentigerous cyst had been removed and enucleated surgically via extra-oral approach because the location of the ectopic impacted tooth was in the ramus of mandible. Extra-oral removal of ectopic mandibular third molar is very rare, however this approach will facilitate an easy removal and enucleation of an extremely malpositioned mandibular third molar associated with dentigerous cyst and minimize a loss of healthy mandibular bone.

Introduction: Maxillary canines are usually impacted teeth the second after third molar. Frequency of impacted maxillary canines is about 1 to 3% of population (in 85% of the cases palataly, and in 15% of the cases bucaly). The aim of this research was to find the frequency of bucal and palatal impacted maxillary canines in relation to sex and position of impacted tooth. Matherial and method: We analyzed three-dimensional computed tomography images (CBCT) of 64 examinees (aged 12 to 33 years) with 80 unerupted maxillary canines to plan the orthodontic therapy. Results: Among 64 examines with impactions, 80 impacted maxillary canines are diagnosed. The average age of all respondents in the survey is 16,3±4,3. Of 64 examinees in research 41(64.1%) were female which is significantly more important than the representation of male examinees whose number was 23(35.9%). Frequency of unilateral impactions of maxillary canines is three times higher 48 (75%) in comparison to bilateral impactions 16 (25%). Of total 80 impacted maxillary canines 19 (23.75%) were bucal impacted, 3 (2.75%) in the middle of alveolus and 58 (72.5%) palatally. With the bucal and palatal impaction usually was represented partially vertical impaction (70%); completely horizontal impaction (10%) was represented only in the palatal impaction. Conclusion: The analysis of CBCT images of maxilla shows a statistically significant frequency of partially vertical, unilateral and paltally localized impacted maxillary canines.

Supernumerary teeth may be encountered as an incidental finding on a radiograph. When impacted, they may be associated with clinical signs related to different problems such as failure of eruption, teeth displacement, root resorption or cystic lesions. They may occur in primary and permanent dentition, in both the maxilla and mandible and can be single or multiple in patients with syndromes. Mesiodens is the most commonly impacted tooth and appears between the central maxillary incisors in pediatric ages. Supernumerary teeth distal to the third molar are rare, usually impacted and referred to as a distomolar. A 46-year-old male consulted with the main complaint of pain on the left side of the maxilla. A panoramic radiograph revealed a right impacted maxillary fourth molar located posterior to the third molar associated with a pericoronal radiolucency. The supernumerary tooth was removed surgically under local anesthesia and the pericoronal lesion enucleated. Histopathological examination was consistent with the diagnosis of a dentigerous cyst associated with an impacted distomolar. Healing was uneventful, and the patients remained asymptomatic. The occurrence of a maxillary distomolar is rare and even rarer the association with a dentigerous cyst.

ABSTRACT Background Third molars are one of the most commonly impacted teeth in the oral cavity. But in very rare cases, the impacted molars can be inverted as well. In this case, the patient presented with an inverted and impacted left maxillary third molar. The aim of the operating surgeon was to execute the procedure in the least hazardous manner, to avoid any surgical complications. Methods The surgical extraction of the tooth by lateral transposition method was carried out rather than the classical method owing to the inverted position of the impacted tooth. The surgery was carried out under local anesthesia. An incision was made at the crest of the ridge with an anterior releasing incision. Bone overlying the impacted molar was removed following which the tooth was luxated and laterally transposed. The socket was thoroughly irrigated and closure was done by simple interrupted suture, using 3-0 mersilk. Results The impacted and inverted maxillary third molar was successfully removed by lateral transposition method without any complications. Conclusion The impacted and inverted maxillary third molars are not commonly encountered in dental practice. Subsequently, their removal can be a challenging job on the part of an oral surgeon. The surgeon should preoperatively weigh carefully the associated risk factors and explain them thoroughly to the patient. How to cite this article Chhabra S, Chhabra N, Dhillon G.
