Background Langerhans cell histiocytosis (LCH) is a rare disorder of the reticuloendothelial system with unknown etiology. This report aims to present a case of LCH with diffuse involvement of the oral cavity and to raise awareness of the distinguishing features of this diagnostically challenging entity. Case ReportA 26-year-old male patient presented with complaints of teeth mobility, intense pain, and difficulty in chewing. Intraoral and radiological examinations revealed generalized gingival hyperplasia and severe teeth mobility with widespread alveolar bone loss. Periodontal therapy was performed with no significant improvement. An incisional biopsy revealed Langerhans cells and positive reaction to S-100 and CD1, and the patient was diagnosed with LCH. The patient underwent systemic chemotherapy with vinca alkaloids and corticosteroids. Regression of gingival lesions, as well as significant decrease in mobility of the remaining teeth and severity of pain, was achieved during 12 months of follow-up. ConclusionThe rarity and variable system involvement of LCH necessitate a multidisciplinary approach be carried out for accurate diagnosis, effective treatment, and an uneventful follow-up. Awareness of oral manifestations of LCH may aid clinicians greatly in reducing morbidity and mortality associated with this debilitating condition.
Treatment of advanced BRONJ lesions with a combination of antibiotic therapy, surgical removal of the lesion, and consecutive low-level diode laser applications provided favorable results in all patients. In consideration of our findings, it can be assumed that LLLT may serve as a safe and effective adjunct to medical-surgical treatment of BRONJ lesions.
Objectives This study sought to investigate the association between the systemic intake of proton pump inhibitors (PPI) and the early failure of dental implants. Materials and Methods A retrospective cohort study involving 1,918 dental implants in 592 patients (69 implants in 24 PPI users and 1,849 implants in 568 nonusers, respectively) was conducted. The effect of PPI intake on the osseointegration of dental implants was evaluated using patient- and implant-level models. Results Among 24 PPI users, two patients experienced implant failure, one of whom had three and the other of whom had one failed implant, respectively. Thus, the rate of failure for this population was 8.3%. Separately, 11 nonusers each experienced one implant failure, and the failure rate for these patients was 1.9%. Fisher's exact test revealed statistically significant differences between PPI users and nonusers at the implant level ( P =0.002) but failed to show any significance at the patient level ( P =0.094). The odds of implant failure were 4.60 times greater among PPI users versus nonusers. Dental implants that were placed in patients using PPIs were found to be 4.30 times more likely to fail prior to loading. Conclusion The findings of this study suggest that PPI intake may be associated with an increased risk of early dental implant failure.
Eagle's Syndrome (ES) refers to a symptomatic anomaly due to elongation of the styloid process or mineralization of the styloid complex. If not diagnosed timely and treated properly, elongation of the styloid process or the hyper-mineralization of the stylohyoid ligament may eventually lead to complete ossification of the stylohyoid complex. Non-specific head and neck symptoms of the ES may pose diagnostic challenges to the clinician. Therefore it is crucial to include ES among differential diagnosis when evaluating patients with similar head and neck symptoms. Once the diagnosis is confirmed, treatment plan should be tailored in accordance with the individual requirements of the case and performed without delay. Both pharmacological and surgical methods have been described for the treatment of the patients with ES. However for those who suffer from persistent symptoms, surgical removal of the elongated styloid process is the treatment of choice and can be done with an intraoral or an extraoral approach. The aim of this work is to present unusual clinical symptoms and radiologic findings of ES due to complete ossification of the stylohyoid complex. The importance of a correct diagnosis and appropriate treatment are highlighted.Keywords Eagle's Syndrome Á Ossification Á Stylohyoid Á Hypoglossal nerve palsy HistoryA 48-year-old female patient with non-significant past medical history was referred for evaluation and management of unilateral weakness of her tongue. Among her initial complaints were sharp lancinating pain on swallowing, altered speech, dry mouth, left neck swelling, and intermittent loss of taste. Radiographic FeaturesInitial radiographic examination was carried out with a panoramic radiograph, which revealed a voluminous ossified stylohyoid complex on the patient's left side (Fig. 1). Computerized tomography (CT) imaging was obtained to further evaluate the true dimension and angulation of the calcified tissue. Sagittal view (Fig. 2) and the threedimensional CT reconstruction (Fig. 3) demonstrated complete ossification of the stylohyoid complex. DiagnosisClinical examination of the patient revealed a fixated mass, which was firm on palpation in the left submandibular
