Background: Various parameters are known to affect the amount and type of mucosal thickening. The aim of this retrospective study was to investigate these effects through a survey of cone-beam computed tomography (CBCT) images. CBCT scans of 150 patients, which included the area of the MS and maxillary teeth (canine, first premolar, second premolar, first molar, second molar, and third molar), were evaluated retrospectively for the presence of sinus mucosal thickening. The parameters evaluated as possible causes of mucosal thickening were age, sex, tooth type, proximity to the maxillary sinus, endodontic treatment, and periapical lesion. Descriptive statistics and multiple logistic regression were used to analyze the data. A total of 28% of the teeth presented with mucosal thickening, which was associated with periapical lesions in 57.1% of 77 cases. The size of the lesion was the only parameter that was found to be significantly connected to the presence of mucosal thickness. More than 50% of teeth with periapical lesions in the posterior maxilla exhibited mucosal thickening. Other parameters such as age, sex, and the position of the root tips in relation to the MS floor did not influence the probability of developing mucosal thickening.

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.

Ectopic Third Molar

A dentigerous cyst or follicular cyst is a form of odontogenic cyst. It is believed that it forms during the development of the tooth and is associated with pressure exerted by the crown of an unerupted (or partially erupted) tooth on the fluid within the follicular space. Typically, dentigerous cysts are painless and discovered during routine radiographic examination. However, they may be large and result in a palpable mass. Additionally, as they grow they displace adjacent teeth. They almost exclusively occur in permanent dentition. The cyst is lined by stratified squamous non-keratinizing epithelium. About 70% of dentigerous cysts occur in the mandible and 30% in the maxilla. Dentigerous cysts associated with ectopic teeth within the maxillary sinus are very rare. We report radiologic and pathologic features in a rare case of infected dentigerous cyst of maxillary sinus arising from an ectopic third molar in a 21-year-old female patient.

ABSTRACT The odontogenic keratocyst (OKC) has recently been reclassified by the WHO (2005), as keratocystic odontogenic tumor (KCOT) based on clinical, histological and immunohistochemical parameters. KCOT more commonly occurs in the mandible and cases involving the maxilla are infrequent. We report an unusual and rare case of a KCOT of the maxilla in a middle-aged individual with extensive involvement and displacement of the maxillary third molar to the zygomatic region. A discussion of the parameters involved in the reclassification of the lesion as a tumor is presented alongwith a review of literature.

Diagnostic Characteristics

Keratocyst is a benign odontogenic lesion with aggressive behavior, probably derived from the dental lamina. It is frequently located in the posterior part of the mandibular bone in the area of ​​the third molar, mandibular angle and can progress towards the ramus and the body, presenting a direct association with retained dental organs. There is a wide variety of techniques for the treatment of this lesion, such as decompression, marsupialization, enucleation, and en bloc resection, as well as the combination of these with adjuvant methods. The interest in this lesion stems from its high recurrence rate, which is estimated to be 20-30% in the general population, however, at present the use of conservative treatments such as marsupialization and decompression has been chosen. demonstrated greater effectiveness and less recurrence. This is why after treating the lesions it is important to give a long-term follow-up. The objective of the publication is to present the report of a clinical case of a 21-year-old male patient with a diagnosis of odontogenic keratocyst treated with a decompression technique for five months for subsequent surgical enucleation. It has been proven that decompression treatment followed by enucleation and accompanied by adjuvant methods is an adequate therapeutic management for keratocysts as it demonstrates its lower rate of recurrence and its noble behavior with neighboring vital structures. However, in all cases, regular monitoring should be carried out to prevent recurrence of the lesion.
