Objective: Bruxism is a jaw muscle activity disorder characterized by clenching or grinding of the teeth and can be seen in both children and adults. The purpose of this study is to evaluate the parental knowledge about bruxism in children. Methods: A cross-sectional study was conducted with 265 parents whose children were attended at University of Mersin pediatric dentistry and oral and maxillofacial surgery clinics. Children’s ages varied from 6 months to 16 years old. A 20-questioned questionnaire was used to collect the data. IBM SPSS Statistics 22 for statistical analysis (SPSS IBM, Turkey) program was used for the analysis. Re . . .sults: A total of 265 parents (159 were female and 106 were male) participated in the study. The majority of the parents were between the ages of 31-40 (60.8%). The rate of clenching and grinding of teeth during sleep (21.5%) was higher than the rate when they were awake (7.2%). The ratio of the parents seeking treatment for their children because of this harmful habit was very low (3.8%). The majortiy of parents (37.7%) reported that they seek help from dentists. The participants believed that bruxism was associated with dental problems (33.6%) and emotional factors (32.8%). A significant difference was found between the educational background of the parents and the ability to define bruxism. Conclusion: Parents had inadequate knowledge about bruxism in children and this was mostly related to the educational background of the parents. Objetivo: El bruxismo es un trastorno de la actividad muscular de la mandíbula que se caracteriza por apretar o rechinar los dientes y se pueden ver tanto en niños como en adultos. El propósito de este estudio es evaluar el conocimiento de los padres sobre el bruxismo en sus niños. Métodos: se realizó un estudio transversal con 265 padres cuyos hijos fueron atendidos en las clínicas de Odontología Pediátrica y Cirugía Oral y Maxilofacial de la Universidad de Mersin. Las edades de los niños variaron de 6 meses a 16 años. Se utilizó un cuestionario de 20 preguntas para recopilar los datos. Para el análisis estadístico de los datos se utilizó el programa IBM SPSS Statistics 22 (SPSS IBM, Turquía). Resultados: Un total de 265 padres (159 mujeres y 106 hombres) participaron en el estudio. La mayoría de los padres tenían entre 31 y 40 años (60.8%). La tasa de niños que apretan y rechinan los dientes durante el sueño (21.5%) fue mayor que la tasa de los que lo hacen cuando están despiertos (7,2%). La proporción de padres que buscan tratamiento para sus hijos debido a este hábito dañino fue muy baja (3.8%). La mayoría de los padres (37.7%) informaron que buscan ayuda de los dentistas. Los participantes creían que el bruxismo estaba asociado con problemas dentales (33,6%) y factores emocionales (32,8%). Se encontró una diferencia significativa entre la formación académica de los padres y la capacidad de definir bruxismo.

Objectives: The aim of this study is to investigate the effect of internal derangements and degenerative bone changes on the minimum thickness of the roof of the glenoid fossa (RGF). Methods: MRI and cone beam CT records of temporomandibular joints (TMJ) of 68 patients were evaluated retrospectively in this study. The joints were divided into three groups according to TMJ disc status which had been diagnosed in MRI: normal disc status, anterior disc displacement with reduction, and anterior disc displacement without reduction. Cone beam CT was used to evaluate the degenerative bone changes of TMJ and to measure the minimum thickness . . . of RGF. The joints were categorized as "with osteoarthritis (OA)" or "without OA". The findings of OA were determined as erosion, osteophyte, flattening, sclerosis, and pseudocyst. Results: No significant relationship was found between gender and the thickness of RGF (p > 0.05). RGF was found significantly higher in "with OA" group compared to "without OA" group (p < 0.001). No significant difference was found between disc displacement groups for minimum thickness of RGF (p > 0.005). No significant difference was found between condyles without erosion and condyles with erosion for the minimum thickness of RGF (p = 0.272). In the present study, osteophyte, sclerosis, flattening, and pseudocyst were found to be associated with the minimum thickness of RGF. Conclusions: Osteophyte, flattening, pseudocyst, and sclerosis have an influence on RGF thickness. The minimum thickness of RGF is not significantly correlated with internal derangements. Erosion is not significantly correlated with RGF thickness. RGF thickness may be unaffected by the early stages of OA Daha fazlası Daha az

Odontomas are the most common benign tumors of odontogenic origin. Due to the absence of symptoms, they are usually diagnosed on routine radiographs. Odontomas are divided based on their radiographic, clinical and histological features; compound odontoma and complex odontoma. The region can be reconstructed according to the destruction area of these lesions. Large bone defect in the jaw bone is usually reconstructed with autogenous bone graft from extraoral donor sites. In such cases, anterior iliac grafts are preferred most frequently. We reported 32-yearold man was referred to the Department of Oral and Maxillofacial Surgery, asym . . .metry with the facial swelling in the region of the posterior right maxilla. The first diagnostic hypothesis was complex odontoma. In decision of surgical excision of the lesion, followed by the rehabilitation of the zone with dental implants. The resulting defects were enriched with anterior iliac crest bone graft. Odontoma en sık görülen benign odontojenik tümörlerdir. Semptom vermedikleri için rutin radyografilerde teşhis edilirler. Odontomalar radyografik, klinik ve histolojik özelliklerine göre sınıflandırılır; kompound odontoma ve kompleks odontoma. Lezyonların destrükte ettikleri alanın rekonstrükte edilmesi gerekebilir. Geniş kemik defektleri ekstraoral donör alanlardan alınan otojen kemik greftleri ile rekonstrükstreükte edilebilir. Böyle vakalarda sıklıkla anterior iliak greftleri tercih edilmektedir.

The present study investigated individual differences in beliefs in the paranormal phenomena. Paranormal belief has been investigated by the researchers with high school and college students in various countries, USA, Finland, Latvia and South Africa. Such studies explored regarding its connection with magical thinking, sexual differences, fantasy proneness and narcissism. Turkish version of the PBS was translated by Sen and Yesilyurt (2014) with college students enrolled in several departments. A Turkish version of the Paranormal Belief Scale (PBS) was implemented to 235 Turkish Psychology Students at a university in Turkey. Statis . . .tical analysis of the study was carried out by SPSS 24. Participants were undergraduate psychology students enrolled at a mid-size university in central Anatolia. Most of the students defined themselves as believers in some sort of higher power. The main purpose of the study was to uncover important aspects of paranormal activities related to gender and academic levels. In addition, factor analysis was conducted in order to find if any dimensions exist. Results of the study indicated some differences among the students regarding gender and year in college. Beliefs in paranormal activity among academic levels showed that there was no evidence for a relationship with them. However, surprisingly, six subscales of the PBS emerged instead of eight as expected based on the findings Daha fazlası Daha az

Obsessive compulsive disorder (OCD) is a common, chronic, and long-term psychiatric disorder in which the individual feels uncontrollable, recurring thoughts (impulses) and an urge to repeat behaviors (coercion). It is a disorder with mental actions that cannot be prevented from repeating itself. Millions of people around the world suffer from OCD. According to 2017 data (World Health Organization), roughly 2,3% of any population live with this disorder. In the study, environmental factors including sociodemographic characteristics which are among the factors that cause OCD formation were examined. This study was intended to examine . . .the relationship between sociodemographic characteristics and OCD symptoms. Therefore, different types of obsessions and compulsions of the participants have been examined. METHODS:Datawerecollectedfrom62peopleintwomid-Anatoliancities.23(37%)weremale and 39 (63%) were female. Their ages ranged between 17–63 and average age was 32 years. 34 (55%) of them were married, 18 (39%) were single and remaining were separated. Sociodemographic data form, Diagnosis DSM-V, Global Obsessive-Compulsive Scale (OCI-R), and Yale Brown Scale (Y-BOCS) were used for data collection. They received a general psychiatric examination. RESULTS: The results showed that the most common obsessions were transmission and sexual suspicion. In addition, control, washing and questioning were found among the most common compulsions. Regarding the patients, 18 were first time, 29 were repetitive, and 15 were chronic OCD patients. Most common obsession types were found as suspicion, infection, and sexual. Their compulsions were mainly control, washing, avoiding or questioning. 40 of them (64%) indicated not having any internal health problem. Other patients were suffering from various internal health issues such as ophthalmologic problems, migraine, epilepsy, and hernia. The frequency of suffering internal health issues in females (46%) was found to be much higher than males (20%). However, no correlation was found between both genders. Most subjects (58%) reported having a relative person diagnosed with a mental issue especially OCD and depression. CONCLUSIONS: Preliminary results revealed that correlation coefficient between OCD symptoms and number of kids (-0.22) showed that the greater number of kids, the less OCD severity. It was found that age and OCD symptoms had negative correlation. On the other hand, similar to previous studies, OCD severity increases as age rises. Having close relatives with OCD symptoms proves that it has a genetic component. Suffering from any internal disease was another factor that increases the risk getting it. Our data comparing male and female subjects diagnosed with it resulted in inconclusive conclusion and supported previous studies. Finally, our findings correlated with the previous research findings and supported the OCD theories about its causes (biology, genetics and environments). However, more detailed and comprehensive studies should be conducted to get more sound proofs about it and related issues such its risk factors, gender and other features. Daha fazlası Daha az
