Öğe Bilateral twinned teeth and multiple supernumerary teeth: A case report(2008) Tümen E.C.; Hamamci N.; Kaya F.A.; Tümen D.S.; Çelenk S.Dental twinning can result from the fusion of the developing dental germinal elements or the gemination of a single germ. In bilateral anterior and posterior dental twinning, problems such as poor esthetics, dental caries, arch-length problems, and periodontal disease often occur as a result of the irregular morphology. Several treatment methods have been described in the literature with respect to the different types and morphologic variations of twinned teeth, including endodontic, restorative, surgical, periodontal, and orthodontic treatment. This report documents the case of a young patient with an exceedingly rare phenomenon of permanent twinned teeth and multiple supernumerary teeth in both sides of the mandibular and maxillary arches, as a result of combined fusion and gemination.Öğe Comparision of dental arch widths in different types of malocclusions.(2008) Basaran G.; Hamamci N.; Hamamci O.To compare dental arch and alveolar widths of patients with Class III and Class II division 1 malocclusions and those with Class I ideal occlusion. Ninety patients were classified in 3 groups of 30 (15 male and 15 female) according to molar relationship. No subjects had received orthodontic treatment, and in all patients, the primary teeth had completely exfoliated. Dental casts of the 90 subjects were made and photographed with a digital camera on a tripod. Dental cast measurements were taken with a dial caliper to the nearest 0.01 mm. All measurements of all subjects were carried out again 2 weeks later to evaluate the measurement error. Analyses of 1-way analysis of variance demonstrated that (1) there were statistical differences in most of the measurements between the Class I and Class III groups (P>.05) and (2) the Class II division 1 group had differences from other groups (P<.05). This result suggests that transverse discrepancy in Class II division 1 and Class III patients may originate from the maxillary posterior teeth. Maxillary intermolar widths are significantly greatest in Class III, Class I, and Class II division 1 groups, respectively.

Five different types of hereditary sensory and autonomic neuropathy have been identified, to date, with different patterns of sensory and autonomic dysfunction, peripheral neuropathy, clinical features, and genetic abnormalities. Absence of pain and self-mutilation are characteristic findings of this syndrome. Teeth in the oral cavity can cause damage to the oral tissues and tongue. When diagnosed, there should be cooperation between the dentist and neurologist. Using an oral shield prevents biting, and thus tissue trauma can be prevented. Here, we present the case of a 6-month-old boy with congenital insensitivity to pain (hereditary sensory and autonomic neuropathies; HSAN type V) with self-mutilation injuries to his tongue and fingers caused by biting, along with a discussion of treatment strategies. The results of this report suggest that early diagnosis and specific dental management for patients with congenital insensitivity to pain are important for prevention of the characteristic oral and dental problems accompanying this disorder.Öğe Direct composite resin application, and prosthetic management in a patient with hypohidrotic ectodermal dysplasia: A case report(2009) Tümen E.C.; Hamamci N.; Deger Y.; Tumen D.S.; Agackiran E.Ectodermal dysplasia is a rare group of disorders affecting the nails, hair, teeth, and sweat glands to a variable degree. The most common form of ectodermal dysplasia is X-linked hypohidrotic ectodermal dysplasia, which affects males more severely, while heterozygous females exhibit variable severity, ranging from mild to severe, because of inactivation of the X-chromosome. The 7-year, 3-month-old boy presented the classical features of hypohidrotic ectodermal dysplasia, including diffusely sparse hair, eyelashes and eyebrows, severe hypohidrosis, and subsequent problems with thermoregulation, dry skin and fingernail defects. Considering the clinical situation, the age and potential growth of the young patient, a maxillary RPD and mandibular complete denture were determined to be the treatment of choice. HED is usually a difficult condition to manage prosthodontically, because of the typical oral deficiencies and afflicted individuals are quite young to receive extensive prosthodontic treatment, which restores their appearance, for the development of a positive self-image.Öğe Early treatment of excessive open bite and follow up: Case report(2009) Hamamci N.; Ozer T.; Basaran G.; Hamamci O.Multiple factors play role in the etiology of openbite malocclusion. For a successful orthodontic treatment the etiology of the malocclusion must be eliminated. A proper diagnosis of the malocclusion and elimination is an essential factor, especially in open bite cases. In the present case, patient was a seven year one month old boy who had a severe open bite with class I molar relationship and tongue thrust. In the anemnesis of the patient, tonsillectomy and adenoidectomy surgery was reported at the age of four. Also, difficulty in the speach was another important finding of the patient. The final outcome of the treatment was a great improvement in function andesthetics. The main reason this patient could be successfully treated nonsurgically was her initial compliance, and the proper therapy options used during this two-phase treatment.Öğe Maxillary canine-lateral incisor transposition: A case report(2010) Tumen D.S.; Kaya F.A.; Hamamci N.; Tumen E.C.; Berber G.This case report aims to present the orthodontic treatment of a patient who referred to our clinic with a chief complaint of crowding and who had left lateral canine tranposition at maxilla. In the clinical examinations of the patient; severe crowding, retained deciduous canine tooth and dental Angle Class I relation were detected. In the radiographic examinations, impacted and transposed canine tooth was observed. Skeletal Class I relation (ANB: 2°) was observed in cephalometric analysis. Fixed appliances were used in order have the transposed and unerupted canine tooth to erupt. Initially, lateral tooth was completely moved to the place of the canine and the space was obtained for canine in the arch. Then we began to have canine tooth erupt by fixing surgically eruption appliance to canine tooth. After having had an ideal occlusion and canine eruption, canine tooth was grinded to make it look like a lateral tooth and aesthetic of the gingiva at canine was provided by applying connective tissue graft. As a result of the applied orthodontic treatment, a functional occlusion, ideal overjet and overbite relation, and aesthetic smile were provided. In the treatment planning and for the success of the transposed teeth, tooth's position and the multidisciplinary cooperation play a key role.Öğe Multidisciplinary approach to rehabilitation of a patient with lateral incisor agenesis(2012) Izgi A.D.; Dildeş R.G.; Kahraman B.; Hamamci N.; Kale E.Lateral incisor agenesis is an important cause for the esthetic smile disharmony due to strategic location. These clinical cases besides multidisciplinary are always treated under the strong influence of either the orthodontic or the prosthodontic discipline. The first approach consists of orthodontic mesial replacement of the missing lateral with the existing canine and giving it an incisor shape, whereas the last approach constitutes a conventional fixed-partial-denture treatment or implant supported prostheses for the missing incisors. This clinical report represents the multidisciplinary rehabilitation of a 21-year-old male with bilateral congenitally missing upper lateral incisors. After orthodontic therapy and providing the necessary space for the laterals, bilateral implant placement and prosthetic treatment was carried out. Incorporation of zirconium reinforced abutments and all ceramic crowns to the therapy had provided attractive and confident smile for the patient.Öğe Noncompliance therapy: Veltri appliance.(2009) Doğan K.; Başaran G.; Hamamci N.; Hamamci O.To achieve intraoral molar distalization without any extraoral appliance or patient cooperation. The intraoral distalization technique was performed on a female 12 years 8 months of age with cooperation deficiency, and the positive results are presented. The patient initially accepted the headgear planned at the beginning of treatment, but she did not wear it long enough. We therefore abandoned the use of extraoral appliances and employed intraoral distalization instead. We preferred to use a Nance button Veltri appliance we could create in our clinic. Once the patient had accepted our new treatment plan, we completed the distalization process in about 2 months. After a 2-month retention period, we completed treatment with a fixed Roth edgewise appliance and maximum anchorage in the maxilla for approximately 18 months. Following treatment, a Class II Division I dental relationship became a Class I relationship in both the canine and molar regions, and a functional occlusal relationship and esthetic facial appearance were obtained. This appliance can be used when patient cooperation is compromised. COPYRIGHT © 2008 BY QUINTESSENCE PUBLISHING CO, INC.Öğe Oral manifestations of lamellar ichthyosis; a case report(Brieflands, 2009) Bolgül B.; Hamamci N.; Akdeniz S.; Çelenk S.Background: The name ichthyosis is derived from the Greek ikhthus meaning "fish" and refers to the similarity in appearance of the skin to fish scale. The ichthyoses are a heterogeneous group of disorders. There are few studies about the oral manifestations of these disorders. But early reports of ichthyosis in the Indian and Chinese literature date back to several hundred years. Case Presentation: Oral manifestations of the 14-year-old female patient with ichthyosis are presented. Physical examination revealed thick, brownish scales covering the entire body surface including all larger body flexures and corneae. She had short and dry hair. There were no nail abnormalities and hearing loss. Conclusion: We consider that this patient represents a new manifestation of lamellar ichthyosis disease, because congenitally teeth missing and cephalometric analysis measurements have not been reported before. © 2009 by Pediatrics Center of Excellence, Children's Medical Center, Tehran University of Medical Sciences, All rights reserved.Öğe TNF-?, IL-1? and IL-8 levels in tooth early levelling movement orthodontic treatment(2010) Kaya F.A.; Hamamci N.; Basaran G.; Dogru M.; Yildirim T.T.During orthodontic treatment, the early response of periodontal tissues to mechanical stress involves several metabolic changes that allow tooth movement. The aim of the present study was to determine tumor necrosis factor alpha (TNF-?), interleukin 1? (IL-1?) and interleukin 8 (IL-8) levels in GCF in tooth early levelling movement orthodontic treatment. Seventeen patients, 8 female and 9 male individuals (aged: 16-20 years; mean 18.2 ± 1.4 years), participated in this study. Each subject underwent a session of professional oral hygiene and received oral hygiene instructions. Three months later, a fixed orthodontic appliance was placed. The patients were seen at baseline and between 1-7 days levelling of the teeth. The concentration of TNF-?, IL-1? and IL-8 were shown in Tables 1. There were statistical differences between the observations at the 1-2 day of levelling for TNF-?, IL-1? and IL-8 (p<.05). Orthodontic forced induces rapid release of the TNF-?, 1L-1? and IL 8 levels during tooth movement in gingival crevicular fluid (GCF). The results of this study support the hypothesis that proinflammatory cytokines play a potent role in bone resorption after the application of orthodontic force in short time.Öğe Treatment of an adolescent with total ankyloglossia.(2010) Hamamci N.; Özer T.; Hamamci O.; Tümen E.C.; Ağaçkiran E.This is a report about the orthodontic treatment of a 13-year, 10-month-old boy with total ankyloglossia combined with a Class III occlusion. The patient's tongue was fixed to the floor of his mouth and could not be elevated at all. He had a maxillary deficiency and a mandibular protrusion with a negative overjet. However, he was able to retrude his mandible to an edge-to-edge position. Before orthodontic treatment, the ankyloglossia was surgically rectified. Orthodontic treatment was initiated to improve the patient's occlusion and facial appearance by correcting his retruded maxilla by means of a face mask, fixed appliances, and Class III elastics. This led to a functional occlusion and an acceptable facial appearance. © 2010 BY QUINTESSENCE PUBLISHING CO, INC.
