1/9. Accessory branch of the mental nerve.This case report presents a surgical case in which an accessory branch of the mental nerve exited the mandible distal and slightly superior to the mental foramen. Careful manipulation of the surgical site allowed proper identification of the mental nerve, and the accessory branch and permanent nerve damage was avoided.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
2/9. Recurrent conventional cemento-ossifying fibroma of the mandible.Cemento-ossifying fibromas are slow growing, benign lesions. recurrence is considered rare. A mandibular periapical radiolucent lesion in a 30-year-old female was diagnosed histologically as a cemento-ossifying fibroma and excised. A recurrence was found 2 years and 6 months postoperatively. CT demonstrated that the recurrent lesion was larger than indicated by conventional radiography.- - - - - - - - - - ranking = 4keywords = mandible (Clic here for more details about this article) |
3/9. Implant periapical lesion: a clinical and histologic case report.A new pathologic entity called implant periapical lesion has been recently described. This lesion could be produced by contamination of the implant surface, overheating of bone, overloading of the implant, presence of a pre-existing bone pathology, presence of residual root fragments and foreign bodies in bone, implant placement in an infected maxillary sinus, implant placement in a poor bone quality site, or lack of biocompatibility. A 49-year-old female patient underwent the placement of a screw-shaped titanium dental implant in the premolar region of the right mandible Six months after implant insertion, the patient presented with a persistent pain resistant to analgesics. No fistula was present at a clinical intraoral examination. A periapical x-ray showed the presence of a radiolucency at the apical portion of the implant; this image was confirmed by a CT Scan. The implant was removed. After implant removal, the pain disappeared completely. The specimen was processed to obtain thin ground sections. The histologic examination showed the presence of necrotic bone in the external and apical portion of the antirotational hole of the implant. The etiology of the implant failure in this instance could be related, probably, to an implant contamination of the apical portion of the implant.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
4/9. Central adenoid cystic carcinoma of the mandible manifesting as an endodontic lesion.AIM: To present a case of adenoid cystic carcinoma (ACC) in the mandible, and manifesting as a periapical lesion. SUMMARY: A 56-year-old male suffered from pain around the right mandibular first molar for approximately 1 week. Oral examination revealed that the involved tooth was restored by a full coverage crown with no obvious abnormalities. A periapical radiograph revealed two ill-defined radiolucencies associated with the tooth, one over the mesial and another over the distal roots of the tooth; incomplete root filling and furcation involvement also being noted. The affected tooth was extracted based on the clinical impression of apical periodontitis. The surrounding tissue of the root apex was curetted and sent for histopathological examination, which revealed ACC. KEY learning POINTS: Adenoid cystic carcinoma affecting the mandible may mimic a periapical lesion. Proper diagnosis of such a lesion is dependent on thorough clinical, radiographic and microscopic examinations. Such a case highlights the benefits of biopsy and histological examination of collected tissues. Diagnosis of lesions in the mandible should include salivary gland tumours.- - - - - - - - - - ranking = 7keywords = mandible (Clic here for more details about this article) |
5/9. Management of apical bone loss around a mandibular implant: a case report.Various terms, etiologies, and treatment strategies have been suggested in conjunction with bone loss limited only to the apical portion of an implant that remains otherwise well osseointegrated. Proposed etiologic factors include bone overheating, microbial involvement of adjacent teeth, pre-existing bone infection, and overload. However, the mandible and maxilla seem to have different predispositions in response to these causative agents. Treatment protocols for peri-implant infection have included minimally invasive approaches such as granulation tissue removal and detoxification of the implant surface, as well as more aggressive measures. This case report demonstrates the achievement of osseous healing and reosseointegration in a patient who presented with presented apical bone loss and signs of infection around a mandibular implant. Reosseointegration was achieved following an intraoral apicoectomy-like approach, ie, removal of the infected nonintegrated portion of the implant, and meticulous debridement of the granulation tissue. A literature review of 13 relevant published studies was conducted. The current understandings regarding the etiology and treatment strategies for management of apical bone loss around dental implants are summarized and presented.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
6/9. Barodontalgia due to odontogenic inflammation in the jawbone.A case is presented of severe anterior mandibular pain, which first appeared during descent of a long commercial flight, and lasted 3 d for a 28-yr-old military helicopter pilot. Apical periodontitis due to pulpal necrosis of the #31 tooth was diagnosed as the causative pathology of the pain. This pain was not ever felt in his daily routine helicopter flights, up to 6000 ft, only in the pressurized chamber of a commercial flight to 7000-ft conditions. Although barodontalgia, dental pain evoked by barometric pressure change in an otherwise asymptomatic tooth, has relatively low prevalence nowadays, it seems that periodic dental vitality tests and panoramic imaging of the jaws are worthwhile for aircrew members.- - - - - - - - - - ranking = 0.33488419167611keywords = jaw (Clic here for more details about this article) |
7/9. Intrabony lymphoma simulating periradicular inflammatory disease.Intrabony lymphoma can mimic periradicular inflammatory disease of pulpal origin. Mismanagement of such cases can result if the clinician presumes the condition is inflammatory and fails to submit a tissue specimen for evaluation. This article reviews the features of jaw lymphoma and documents the importance of early diagnosis and histopathologic examination.- - - - - - - - - - ranking = 0.066976838335223keywords = jaw (Clic here for more details about this article) |
8/9. Traumatic bone cyst resembling apical periodontitis.Among the pseudocysts of the jaws, the traumatic bone cyst is known as an asymptomatic lesion often noted unintentionally during routine radiographic examinations. The lesion neither devitalizes the teeth within its borders, nor does it cause resorption of their roots. The well-demarcated traumatic bone cyst often projects into the intraradicular septa and hence has been described as having scalloped borders. The following presentation is of a traumatic bone cyst that resembled periodontal pathology in its appearance.- - - - - - - - - - ranking = 0.066976838335223keywords = jaw (Clic here for more details about this article) |
9/9. Implant periapical lesions: clinical, histologic, and histochemical aspects. A case report.A new entity, the "implant periapical lesion," has recently been described. The etiology of this condition could be attributed to overheating of the bone, overloading of the implant, presence of a pre-existing infection or of residual root particles and foreign bodies in the bone, implant contamination during production or during insertion, or placement of the implant in an infected maxillary sinus. In this report, a titanium plasma-sprayed implant had been inserted into the mandible of a 53-year-old patient; after 5 months a fistula developed and periapical radiography showed a large radiolucent image around the apical portion of the implant. The implant was removed, and histologic examination showed necrotic bone and an inflammatory infiltrate inside the hollow portion of the implant. The etiology of the implant failure in this instance could be related to a fracture and vascular impairment of the bone inside the implant during insertion, to external contamination of the implant, or to the poor bone quality of the implant site.- - - - - - - - - - ranking = 1keywords = mandible (Clic here for more details about this article) |
