Öğe Bruxism: Is it a new sign of the cardiovascular diseases?(2011) Atilgan Z.; Buyukkaya R.; Yaman F.; Tekbas G.; Atilgan S.; Gunay A.; Palanci Y.Aim: To determine the relationship between bruxism and cardiovascular diseases. Materials and Methods: 120 patients who referred to the Dentistry Faculty with the complaint of bruxism were selected. All patients gave informed consent for participation in the study. All of the patients were examined and bruxism was classified. And also these were examined by B-mode ultrasound to measure the Intima Media Thickness (IMT) at the far wall of the common carotid artery. A wide range of vascular risk factors including age, gender, body mass index, and previous history were surveyed. Spearman correlation analysis was performed to ascertain quantitative comparison, Mann-Whitney U and Kruskal-Wallis test were used for comparison of means Results: There were 66 (55%) male and 54 (45%) female patients, with a female to male ratio of 1/1.2. The mean age was 35.6 ± 1,25 years (range 18-65 years). In the analysis of bruxism classification and IMT there was a statistical significance between bruxism classification subgroup 1, 2, 3 and IMT. There was no statistical significance between bruxism classification Subgroup 4 and IMT due to the small number of the patients (n=12). Conclusions: Stressful situations can cause both bruxism and cardiovascular disease such as coronary artery diseases, hypertension, arrhythmias, cardiomyopathy. The statistical analysis supported this hypothesis. However, we need to new studies with large number of samples to confirm this hypothesis. Clearly, future studies in this field will need to take into consideration the influence of the following variables: age, use of medication or drugs, smoking habits, and other sleep disorders.Öğe Dentigerous cyst with an impacted canine: Case report(2011) Agacayak K.S.; Kose I.; Gunes N.; Bahsi E.; Yaman F.; Atilgan S.Dentigerous cysts are the second most common developmental odontogenic cysts after radicular cyst. They usually present in the second or third decades of life and these cysts are rarely seen during child hood. Their frequency in the general population has been estimated at 1.44 cysts for every 100 unerupted teeth. According to frequency of impaction, the maxillary permanent canine ranks second only to the third molar, with a prevalence of approximately 2% in the general population. Impacted canines are positioned palatally 85% of the time. The frequency of impaction is three times greater in females than males. In many instances the cyst may be asymptomatic till it attains a large size. It usually presents as a slowly enlarging, sometimes painful swelling; particularly if infected. At radiography, dentigerous cysts appear as well-defined, round or ovoid, corticated, lucent lesions around the crowns of unerupted teeth. The radiographic appearance of such dentigerous cysts is comparable with that of cystic, unilocular odontogenic keratocysts. Treatment includes extraction of the associated tooth and enucleation of the cyst. In this study we present dentigerous cyst that caused by impacted canine.Öğe Effects of systemic zoledronic acid administration on osseointegration of hydroxyapatite-coated and resorbable blast material surface implants in rabbit models(2012) Yaman F.; Ağaçayak S.; Atilgan S.; Benlidayi E.; Ucan M.C.; Erol B.; Kaya B.Purpose: It is unknown whether zoledronic acid (ZA) interferes with initial bone healing at implant sites. The goal of this study was to examine the effects of systemic zoledronic acid administration on osseintegration of hydroxyapatite (HA)-coated and resorbable blast material surface (RBM) implants in rabbit models. Materials and Methods: Twenty-eight male New Zealand rabbits (aged 6 to 12 months) were used in this study. Rabbits were randomly assigned to four groups. In group A, HA-coated implants were placed in the right tibia of seven rabbits. In group B, RBM-surface implants were placed in the right tibia of seven rabbits. In group C, HA-coated implants were placed in seven rabbits with intravenous (IV) administration of ZA. Finally, in group D, RBM-surface implants were placed in seven rabbits with IV administration of ZA. For groups C and D, IV zoledronic acid (0.1 mg/kg) was performed monthly during the entire osseointegration period. All of the rabbits were sacrificed 12 weeks after the implantation, and tibial specimens were harvested. Histomorphometric boneto- implant contact (BIC) analysis and the data were statistically analyzed. Results: The highest BIC percentage was detected in group D, with a mean value of 56.73% ± 1.85%, as compared with 45.80% ± 3.77% in group C, 35.11% ± 0.76% in group B, and 31.14% ± 1.04% in group A. Conclusions: Histomorphometric analyses showed significant improvement in the osseointegration of implants in the RBM-surface ZA group compared with the HA-coated ZA group. The results of this study suggest that systemic ZA administration may improve osseointegration of titanium implants in bone. © 2012 by Quintessence Publishing Co Inc.Öğe Interesting case: An unusual location for a large pleomorphic adenoma arising in the maxilla(2010) Tanrikulu R.; Yaman F.; Atilgan S.; Gunes N.; Gorgun B.Pleomorphic adenoma is the most common benign tumor of the major salivary glands, especially of the parotid gland. It is much less common in the minor salivary glands of the oral cavity, and it rarely occurs in others sites in the head and neck (intraosseous, lacrimal gland, chest). A 51-year-old woman was referred to our department complaining of painless swelling of the left maxillary vestibular sulcus, which had been felt pain with the pressure. CT scan revealed a well defined expansile mass arising from pterygoid plates, infratemporal space to palatinal bone and arcus zygoma. Transoral biopsy specimen showed pleomorphic adenoma. Patient was treated by surgical excision. Follow up goes on in postoperative period. Our study's aim is to present the pleomorophic adenoma's case which is extended up large propotion in an unusual location. Our case is evaluated by in terms of diagnose and treatment result. Furthermore in the light of literature reviews we discuss the pleomorphic adenoma's incidence, location, and recurrence rates. We believe that our presentation is very interesting in point of view rare location and expansive mass.
