Introduction: Treatments with dental surgery seek to displace tooth to the correct position within the dental arch. Objective: To report a clinical case that took advantage of an unerupted third molar. Case history: A male patient, 18 years of age, was referred by his dentist to evaluate the third molars. The clinical exam revealed no visible lower third molars. The computed tomography (CT) exam showed the presence of a supernumerary tooth in the region of the mandibular ramus, on the left side, and impaction of the third molar, which was causing root resorption on the second molar, thus making it impossible to remain in the buccal cavity...

BACKGROUND: The aim of this study was to compare OPG and CT accuracy in predicting inferior alveolar nerve (IAN) injury after lower wisdom teeth extraction. METHODS: 23 patients with completely impacted lower third molar were enrolled in this study and OPG and CT exams were obtained before surgical intervention. Finally, a total of 26 lower third molars were extracted and cases of paresthesia following a IAN lesion have been registered. Then, OPG and CT images of the same patients have been randomly submitted to four experienced oral surgeons (with a seniority of at least 5 years) who were required to predict the possibility of a IAN injury by only evaluating the radiological exams...

BACKGROUND: Dental fear is usually associated with hemodynamic changes. Fear of pain during the surgical removal of a lower impacted third molar might cause patients anxiety, thereby leading to avoidance of any future dental therapy. This study aimed to determine the effect of experiencing a surgical impacted-tooth removal on the pain perception-related anxiety and hemodynamic status. METHODS: Twenty-seven healthy patients aged 15-30 years (mean age, 24 years), for whom surgical removal of bilateral lower third molars was advised, were included...

BACKGROUND: The odontogenic cystic lesions happened in the angle and ramus region are frequently associated with impacted mandibular third molars. The treatment plan was difficult to work out for the huge cystic lesions with deeply impacted third molars, since the enucleation with simultaneously removing the deeply impacted teeth may cause serious complications. Therefore, the marsupialization of the cystic lesions followed by enucleation with tooth removal has also been advocated. The aim of this study was to explore the movement of cystic lesion-associated deeply impacted mandibular third molars (IMTM) after marsupialization...

Dental pulp stem cells (DPSCs) have been proposed as a promising source of stem cells in nerve regeneration due to their close embryonic origin and ease of harvest. Resveratrol (RSV) is a natural polyphenolic and possesses many biological functions such as anti-inflammatory activity and protection against atherosclerosis and neuroprotective activities. There is increasing evidence showing that RSV plays a pivotal role in neuron protection and neuronal differentiation. In this study, we isolated DPSCs from impacted third molars and investigated whether RSV induces neuronal differentiation of DPSCs...

Clinical use of zoledronate is accompanied with osteonecrosis of the jaw but the pathogenesis is not well understood. We assumed that zoledronate may have cytotoxicity against stem cells of the oral cavity, and in this way helps to initiate or promoting osteonecrosis. Dental pulp stem cells (DPSCs) and gingival fibroblasts (GFs) were isolated from volunteers who were undergoing third molar extraction. The proliferation of DPSCs and GFs was evaluated using thiazolyl blue tetrazolium bromide assay. Effect of zoledronate on apoptosis was determined by propidium iodide staining and western blotting analysis...
