Impacted Lower Third Molar Fused with a Supernumerary Tooth —Diagnosis and Treatment Planning Using Cone‐Beam Computed Tomography

This paper reported a case of fusion between an impacted third molar and a supernumerary tooth, in which a surgical intervention was carried out, with the objective of removing the dental elements. The panoramic radiography was complemented by the Donovans radiographic technique; but because of the proximity of the dental element to the mandibular ramus, it was not possible to have a final fusion diagnosis. Hence, the Cone‐Beam Computed Tomography—which provides precise three‐dimensional information—was used to determinate the fusion diagnosis and also to help in the surgical planning. In this case report we observed that the periapical, occlusal and panoramic were not able to show details which could only be examined through the cone‐beam computed tomography.

Clinical and Image Findings in Bisphosphonate-Related Osteonecrosis of the Jaws

Bisphosphonate-related osteonecrosis of the jaws (BRONJ) is characterized as exposed bone in the jaws for more than 8 weeks in patients with current or previous history of therapy with bisphosphonates (BPs) and no history of radiotherapy in the head and neck. We report a case series of 7 patients with BRONJ and analyze the variations of clinical and imaging signs, correlating them with the presence or absence of bone exposure. Among the patients, 6 were women and 1 was a man, aged 42-79 years. Five of the patients were using zoledronic acid and the other 2 alendronate. The use of BPs varied from 3 to 13 years. In 5 patients, tooth extraction was the triggering event of injuries. Panoramic radiographs and computed tomography (CT) were evaluated by a radiologist blinded to the cases. There were persistent unremodeled extraction socket even several months after tooth extraction in 3 of the cases that were consistent wit CT findings that also showed areas of osteosclerosis and osteolysis. Patients were treated according to the recommendations of the AAOMS, with surgical debridement and antibiotic coverage with amoxicillin in the symptomatic patients. The follow-up of these patients ranged from 8 to 34 months, with a good response to treatment. The image findings in this case series were not specific and showed no difference between each stages of BRONJ (AAOMS, 2009). The image features were similar in presence or absence of exposed bone.

Simultaneous occurrence of dentigerous cyst and residual cyst in the maxilla

The cysts that originate in the remnants of dental lamina or enamel organ are known as odontogenic cysts. They are of great interest to otolaryngologists due to their proximity to the maxillary sinus and adjacent areas.1 Radicular cysts represent 72.5% of all odontogenic cysts, followed by dentigerous cysts (DC) (22.2%), and residual cysts (RC) (4.26%).2 The options for treatment of cystic lesions involve curettage, enucleation, marginal resection,3 and endoscopic surgery, which is a viable alternative, especially in cases of extension to the maxillary sinus.4 A PubMed and EBSCOhost search did not retrieve any studies analyzing the simultaneous occurrence of DC and RC. This article reports a case involving the association a DC and a RC in the upper jaw of an edentulous patient.

Unusual findings on infantile cortical hyperostosis: A case report

BACKGROUND Caffeys disease is a rare syndrome, usually self-limiting, affecting newborn and young infants. On radiological exams, the cortical hyperostosis is always present, associated or not to soft tissue swelling. Other radiographic presentations are described as lytic areas. AIM This article has the objective to relate computed tomography (CT) findings of Caffeys disease, where lytic lesion on mandibular angle was the principal radiological manifestation. METHODS AND RESULTS Three-dimensional reconstructions were performed to demonstrate the initial aspect and the healing process. CONCLUSION This report shows unusual radiological characteristics of Caffeys disease on CT and its progressive resolution.

Radiographic study of mandibular third molars: evaluation of the position and root anatomy in Brazilian population

ObjectivesThe root anatomy and position of mandibular third molars are important factors in assessing the level of difficulty of surgical removal procedures. In this light, this study aims to identify the most frequent position and the root anatomy of mandibular third molars.MethodsThe study sample comprised 1205 mandibular third molars from 710 panoramic radiographs evaluated. Regarding the position, all of them were based on Pell and Gregory’s and Winter’s classifications. The root anatomy was classified according to the type and number of roots, as well as the presence of laceration, fusion, or divergence. Gender and the quadrant were also considered. Following an interexaminer analysis, a statistical analysis was performed using the Kappa test.ResultsThe results showed that the IA (40.3%) and mesioangular (53.8%) position was predominant in mandibular third molars. Regarding the anatomy, the most common were two roots (98.3%), of the conical simple type (88.9%), with absence of laceration (89.2%), divergence (84%), and fusion (80%).ConclusionThe present study showed that the most prevalent mandibular third molar type in Brazilian patients was the IA and mesioangular position, with simple root anatomy. The result of this study can assist oral surgeons to better plan and assess the level of difficulty of surgical removal procedures.

Surgical management of palatine Torus - case series

Introduction: Torus palatinus is a specific name to identify exostoses developed in the hard palate along the median palatine suture. Despite of not being a pathological condition, its presence requires attention and knowledge regarding its management. Surgical removal of exostoses is indicated when the patient frequently traumatizes the area of palatine torus during mastication and speech or when it is necessary for the rehabilitation of the upper arcade with complete dentures. Objective: The aim of this article is to present three cases of Torus palatinus and to discuss the management of them. Case report: In the first case, a 57-year-old Caucasian man sought oral rehabilitation of his edentulous maxilla but presented a hard nodules in the hard palate; in the second case, a 40-year-old Caucasian woman was referred for frequent trauma of palatal mucosa during mastication, aesthetic complaint, and discomfort caused by the trauma of her tongue in this area; and in the third case, a 45-year-old Caucasian woman presented with a lesion on the palate that caused difficulty swallowing. When the Torus palatinus was impairing the basic physiological functions of the patients, all cases were surgically treated, improving the patients’ quality of life. Final consideration: The dentist should be properly prepared to choose the best from among the existing surgical approaches for each individual lesion in order to improve the results and avoid possible complications.
