    Congenital Insensitivity to Pain: A Case Report with Dental Implications
    (Medcom Ltd, 2010) Bolgul, B. Sezgin; Hamamci, N.; Agackiran, E.; Celenk, S.; Ayna, B.
    Congenital insensitivity to pain is a rare disorder seen in early childhood. 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.

    THE DETAILED EVALUATION OF SUPERNUMERARY TEETH WITH THE AID OF CONE BEAM COMPUTED TOMOGRAPHY
    (Taylor & Francis Ltd, 2010) Tumen, E. C.; Yavuz, I.; Tumen, D. S.; Hamamci, N.; Berber, G.; Atakul, F.; Uysal, E.
    The aim of this paper is to demonstrate the application of a recently developed three-dimensional imaging system, cone beam computed tomography, in the detailed evaluation of supernumerary teeth. Two-hundred and twenty three patients with supernumerary teeth (68 females and 155 males) were included in this study. Patients ranged in age from 12 to 25 years. Supernumerary teeth were detected by clinical examination and traditional radiographies. Moreover careful investigation for more details was made with the cone beam computed tomography. Supernumerary teeth which were detected with the examinations of the cone beam computed tomography images were classified according to the number location, shape and eruption rate. The prevalence of supernumerary teeth was determined to be 1.45% of the study population. Males were affected more than females in a ratio of 2.3:1. Supernumerary teeth were most frequently located in 86.2% of the cases in the maxilla; 10.1% in the mandible and 3.7% both in the maxilla and mandible. Supernumerary teeth were most commonly conical in shape (68.8%). One supernumerary tooth was present in 67.7% of the patients, 30.9% had two, and 1.4% had three supernumeraries. Definite and early diagnosis of the supernumerary teeth is very important. Detailed examinations and evaluations of these teeth with three-dimensional images is very benefical in terms of treatment planning and preventing complications which may occur

    Evaluation of the relationship between sagittal anomalies and the presence of third molars in two different periods in Turkish orthodontic patients
    (Diagnosis Press Ltd, 2008) Hamamci, N.; Basaran, G.; Uysal, E.
    The purpose of this investigation was to evaluate the existence of third molar germs in orthodontic patients in Turkey, to examine the correlation between the existence of third molars and sagittal maxillomandibular jaw relationships and to compare the presence of third molars in individuals born in the 1970s and 1990s. The subjects were of 450 patients attending the orthodontic clinic Dicle University aged younger than 15 years. The subjects were divided into two groups: Group I, consisted of 150 patients (50 males and 100 females) born between 1975 and 1979, and group 2300 patients (124 males and 176 females) born between 1990 and 1997. Assessments were made from panoramic radiographs and lateral cephalograms. The chi square test were present in 71.5 percent of subjects, (2) a non-significant decrease was determined in the level of third molars present in individuals group 2. (p > 0.05), (3) mandibular third molars were present significantly more often than maxillary third molars(p < 0.001), (4) no statistically significant difference was found among the prevalences of third molars in all Angle classifications in the sagittal plane (p > 0.05) and (5) the percentage of skeletal Class II subjects who had all four third molars was higher than that of skeletal Class III subjects.
