Complete replacement resorption after replantation of maxillary incisors: Report of case

PubMed ID: 10551136This article describes the treatment of a 17-year-old patient with complete root resorption of the maxillary permanent central and lateral incisors following avulsion and replantation seven years ago. The most important factor influencing the prognosis of replanted teeth is the status of the periodontal ligament (PDL). As a result of replantation, the PDL cells necrosed and tooth replacement resorption occurred. The main factors, which affected the resorption after replantation and survival of PDL cells, could be summarize as; dry extraoral time greater than 30 minutes, the kept tooth in a dry environment, touching the cementum surface, and splint treatment for a prolonged time. Since complete root resorption was found in our case, these factors probably also occurred

Evaluation of the Effect of Apical Lesion on Mucosal Thickening and Thickness of Apical Bone Using Limited Cone-Beam Computed Tomography

WOS: 000441644300002PubMed ID: 30073994Objective: The purpose of this study was to evaluate the effect of periapical lesion size on the degree of mucosal thickening of maxillary sinus and thickness of apical bone using cone-beam computed tomography. Materials and Methods: In Group 1 (teeth with apical lesions), diameter of apical lesion, width of apical bone, thickness of Schneiderian membrane; for Group 2 (teeth without apical lesions), width of apical bone in long axis of root and thickness of Schneiderian membrane were measured on coronal and sagittal images. Results: Mann-Whitney U-test revealed no significant difference between two groups regarding mucosal thickening and apical bone measurements (P > 0.05). Wilcoxon signed-rank test showed no significant difference between the measurements in sagittal and coronal slices (P > 0.05). Conclusion: Results of the present study showed that Schneiderian membrane near the maxillary premolars and molars with apical lesions is not significantly thicker compared to teeth without apical lesions

Morphological Assessment of Maxillary Sinus Septa Variations with Cone-Beam Computed Tomography in a Turkish Population

Objective The purpose of this study was to measure and classify sinus septa variables (prevalence, numbers, heights, locations, orientations, and morphology) and to determine the effects of age, gender, and dental status on the presence of septa and also to evaluate the effects of septa on pathological mucosal thickening. Materials and Methods A total of 2,000 patients were analyzed through conebeam computed tomography (CBCT). The total of 500 maxillary sinuses were included in this study. The number of maxillary sinus septa was determined on axial sections of CBCT images. Their locations, orientations, and morphologies were determined on both the axial and sagittal sections, and their heights were determined only on the sagittal sections. The influence of age, gender, dental status, and pathological mucosal thickening on the presence of septa was statistically analyzed. Mann-Whitney U-test and descriptive statistics were used for statistical analysis. Results The average height of the determined 287 septa was measured as 7.36 mm. The highest rates of septa location, morphology, and orientation were found, respectively, in the middle region septa (57.49%), completed septa (75.95%), and transverse septa (93.37%). The effect of dental status, age, and gender on the presence of septa was not statistically significant (p > 0.05). Conclusion These high rates of findings support the importance of CBCT in the diagnosis of the variations of the maxillary sinus septa. Therefore, it is important to evaluate CBCT images of the relevant region to increase the success of surgical interventions in the maxillary posterior region and to eliminate possible complications. © 2019 Dental Investigation Society

Facial subcutaneous calcinosis and mandibular resorption in systemic sclerosis: a case report

WOS: 000247431700009PubMed ID: 17463103Systemic sclerosis (SSc) is an autoimmune disease characterized by widespread fibrosis of subcutaneous connective tissue, causing serious complications with the involvement of other systems. Tight, firm skin is the main characteristic of SSc, causing extrinsic pressure and the obliteration of the vessels. This then leads to ischaemia and destruction of the underlying bone. This mechanism may also lead to bone resorption of the mandibular body as it affects other bones of the skeleton. To date, only two cases of reported calcinosis in the facial area have been observed. In this report, a rare case of SSc with both subcutaneous calcinosis and mandibular bone resorption is presented. The role of dental practitioners in the diagnosis of the disease with respect to the orofacial symptoms is also discussed

Multidisciplinary management and long-term follow-up of mesiodens: A case report

PubMed ID: 19093654Supernumerary teeth are relatively common in the oral cavity and are characterized by an excessive number of teeth. The term "mesiodens" refers to a supernumerary tooth located in the midline of the maxilla between the central incisors. Mesiodens may cause a variety of pathological complications such as impaction of the maxillary central incisors, tooth retention or delayed eruption of the permanent incisors, crowding, eruption within the nasal cavity, formation of diastema, intraoral infection, root anomaly, root resorption of adjacent teeth and cyst formation accompanied by bone destruction. Therefore it is recommended to follow-up with regular radiographic examination. Early diagnosis minimizes treatment needs and prevents associated complications. The present case, followed for 7 years, presented bilateral mesiodens resulting in delayed eruption of the permanent incisors and emphasizes the importance of multidisciplinary management and long-term follow-up

The oral manifestations of Maroteaux-Lamy syndrome (mucopolysaccharidosis VI): A case report

WOS: 000237068400013PubMed ID: 16632276Maroteaux-Lamy syndrome is one of the genetic disorders involving disturbances in mucopolysaccharide metabolism resulting in increased storage of acid mucopolysaccharide in various tissues. The basic defect in Maroteaux-Lamy syndrome is a deficiency of arylsulfatase B, which leads to accumulation of dermatan sulfate in tissues and their urinary excretion. The deposition of mucopolysaccharides leads to a progressive disorder involving multiple organs that often results ill death in the second decade of life. This disease, which has several oral and dental manifestations, is first diagnosed on the basis of clinical findings. A large head, short neck, corneal opacity, open mouth associated with an enlarged tongue, enlargement of skull, and a long antero-posterior dimension are the main characteristic features. Dental complications can be severe and include unerupted dentition, dentigerous cystlike follicles, malocclusions, condylar defects, and gingival hyperplasia. An 11-year-old boy with Maroteaux-Lamy syndrome (mucopolysaccharidosis type VI) is described in this article, with special emphasis on the oral manifestations
