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.

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.

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

Paranormal beliefs are of interest for the college students especially studying psychology and philosophy. In addition, attitudes such as parental bonding and adult attachment affect levels of paranormal beliefs. Exploring the relationships among these principal themes is of great importance in illuminating possible effects of students’ attachments and bonding toward the development of paranormal beliefs. The purpose of this study is to examine the relationship among students’ parental attachment, relationship attitude, and paranormal beliefs; 239 university students responded to the items in three separate questionnaires, the Paran . . .ormal Belief Scale, parental bonding, and adult attachment survey. The research findings showed that a significant relationship exists between paranormal beliefs and attachment attitudes in the favor of females. In terms of the relationship between paranormal beliefs and adult attachment, the results also revealed that they have akin relationships between adult attachment and parental bonding. Although adult relationships affect paranormal beliefs, no significant correlation was found among three areas possible because the effect of parental bonding is limited in the long term Daha fazlası Daha az

he purpose of this study was to investigate males' perspectives on sexuality. Sexual identity, demographic factors and sexual functioning in males are important to examine how they perceive and understand when it comes to sexuality before and after the marriage. Few studies were conducted on male sexuality in Turkey. A total of 78 healthy heterosexual males volunteered in order to collect data for this research. Due to the potential insufficiency for the necessary number of participants, they were selected with the snowballing data collection technique. Their ages ranged between 23 and 57 years old with an average of 30. Most of the . . .m (61%) were either married or being in a relationship. They agreed to participate in this study and responded the items in two questionnaires, demographic data form, and sexual history questionnaire. Questionnaire items included biological sexual identity and sexual orientation questions. The items on both forms were semistructured, prepared by the researchers with implementing related previous studies. Findings showed that most of the participants had a sexual interest in others including the girlfriend, neighbor, schoolmates, and relatives during adolescence and adulthood times. Their sexual functioning was sexual intercourse during these periods. They mainly masturbate, prefer coitus at home at least twice a week, and highly satisfied with their sexual life. According to our results, like masturbation habits, Turkish males showed similar sexual behaviors and functioning compared to their international counterparts. Their sexual behaviors transform into adulthood, from erotic fantasies to physical sexual activities. Several males (70%) continued masturbation after marriage, which was an unexpected result. 23% of the male participants normally don’t expect extraordinary desires from their partners and almost none of the partners expect them, either. They hold thoughts of sexual fantasies more than partners Daha fazlası Daha az
