Öğe Dentist visits of Syrian refugees and the cost of their dental healthcare(2019) Koparal, Mahmut; Ege, Bilal; Keskinruzgar, Aydin; Yapici Yavuz, Gunay; Erdogmus, Zozan; Unsal, Mustafa NafizAim: To investigate dental problems of Syrian refugees in southeast Turkey and assess the burden of their dental healthcare costs to government. Material and Methods: A retrospective study included dental records of Syrian refugees who applied to Adıyaman Dental Hospital (ADH), were compared with Adıyaman public by years.Results: In 2012, the most common treatments were tooth extraction and complicated tooth extraction, the total dental care cost of such refugee patients was $3,082.14 and the median cost per refugee was $4.43. The most common treatment provided to both the Adıyaman public and Syrian refugees in 2017 was dental filling. In the same year, total dental care cost of refugees was $603,303.69, the median cost per refugee was $22.20. The total dental care cost of the Adıyaman public was $3,869,524.96, the median dental care cost in Adıyaman public was $17.95 for one person in 2017.Conclusions: Dental problems of Syrian refugees and the financial burden of their dental healthcare to the government significantly increased.Keywords: Refugee; dental care cost; Syrian; immigrant; treatment; budgetÖğe Evaluation of bone resorption after implant surgery: Analysis of short-term follow-up(2019) Keskinruzgar, Aydin; Ozcan Kucuk, AyseAim: The aim of this study was to investigate the amounts of marginal bone resorption around the implant that occurs after the implant surgery before the prosthetic loading by evaluating the patients who received implants in oral and maxillofacial surgery clinic. Material and Methods: Two hundred and fifty-three implant surgeries that were performed in the period from 2016 to 2017 were included in this study. The panoramic X-rays taken immediately after implantation and before prosthetic loading at 3 months were evaluated. The marginal bone resorptions around the implants were measured and these values were compared with respect to the gender of the patient and the size of the jaw areas. Results: Implant surgeries were performed on a total of 91 patients (50 females and 41 males). The mean age of the patients was 46.03 ± 12.13 years. One hundred and forty-four implants were evaluated in male patients, while 109 implants were evaluated in females. Marginal bone resorption around the implants in males was observed to be statistically significantly higher than in females (p=0.00). There was no statistically significant difference (p=0.76) between the resorption values of mandible and maxilla. Resorption values in the molar region in the jaws were significantly higher than the amount of resorption in the anterior region (p=0.17). Conclusion: In this study, the marginal bone resorption around the implant was assessed between the implant surgery and the prosthetic loading, where it was found to be 0.24 mm in mandible and maxilla. In addition, both jaws were observed to have the lowest resorption amount in the anterior region and the highest resorption amount in the molar region.Öğe Evaluation of the presence of effusion in patients with temporomandibular joint disorder(2019) Yapici Yavuz, Gunay; Simsek Kaya, Goksel; Ogul, Hayri; Keskinruzgar, AydinAim: The aim of this study is to investigate the relationship between effusion and disc displacement that were detected in MRIs of temporomandibular joint disorder (TMD) patients Material and Methods: MRIs of 60 patients who had pain and/or dysfunction in the TMJ region were evaluated for the presence of effusion. TMC disc positions of 60 MRI results were divided into three groups: normal disc position (control group, n: 20), disc displacement with reduction (R group, n: 20) and disc displacement without reduction (NR group, n: 20). When evaluating the presence of effusion, hyperintense thin lines or absence of effusion was evaluated as no effusion; while signal intensity of more than 2 mm at the anterior-posterior length or superior-inferior height at the joint space was evaluated as the presence of effusion. Results: According to MRI findings, effusion was observed in 2 of the 20 joints (10%) in the control group, 8 of the 20 joints (40%) in the R group and 17 of the 20 joints (85%) in the NR group. When the groups were compared with each other, there was a statistically significant difference between the groups (p<0.05). Conclusion: In TMD, where normal disc position deteriorates to disc displacement, the prevalence of effusion also increases. It is thought that changes in effusion levels can be used as a marker for evaluating the prognosis of TMD.Öğe Histopathological Effects of Teriparatide in Medication-Related Osteonecrosis of the Jaw: An Animal Study(W B Saunders Co-Elsevier Inc, 2016) Keskinruzgar, Aydin; Bozdag, Zehra; Aras, Mutan Hamdi; Demir, Tuncer; Yolcu, Umit; Cetiner, SedatPurpose: Osteonecrosis of the jaw after tooth extraction is a major complication in patients using bisphosphonates (BPs) for bone lesions, such as for the treatment of osteoporosis. The purpose of this study was to investigate the histopathologic effects of teriparatide (a synthetic parathyroid hormone) on rats developing osteonecrosis with BP use. Materials and Methods: Rats (n = 80) that had been injected intraperitoneally with zoledronic acid for 7 weeks were used. Maxillary first molar extractions and bone defects were established in the same region in the eighth week. Teriparatidewas administered subcutaneously to prevent osteonecrosis. Animals were sacrificed and histopathologic changes were examined. Osteoblasts, osteoclasts, inflammatory phase of bone healing, and osteonecrotic areas were evaluated. Results: The osteoclast numbers were larger in the experimental groups (teriparatide administered before and immediately after tooth extraction) than in the control group (administered zoledronic acid). The inflammatory phase of bone healing was more pronounced in the experimental group (teriparatide administered before tooth extraction) than in the control group. There were significant differences in osteoclast numbers and in the inflammatory phase of bone healing between the experimental and control groups (P < .05). The osteoblast numbers and osteonecrotic areas were similar in size between the experimental and control groups. There were no significant differences (P > .05). Conclusions: BPs have negative effects on osteoclasts and the inflammatory phase of bone healing, whereas teriparatide was found to be effective in eliminating the negative effects of BPs. Teriparatide had positive effects in preventing osteonecrosis; therefore, teriparatide could be an effective agent for MRONJ. (C) 2016 American Association of Oral and Maxillofacial SurgeonsÖğe Inferior alveolar nerve paresthesia due to radicular cyst: A case and review of literature(2019) Ege, Bilal; Koparal, Mahmut; Yapici Yavuz, Gunay; Keskinruzgar, Aydin; Geyik, Abdussamed; Aydin Turk, BilgeRadicular cysts are inflammatory jaw cysts that form in the apices of infected and necrotic pulp teeth. They are usually asymptomatic and tend to grow slowly. However, depending on the progressive size of the lesion and its relation to neighboring tissues, it may cause mobility, root resorption and displacement. In addition, a limited number of studies have been reported in which paresthesia occurs as a result of local pressure caused by periapical pathology and various mandibular intraosseous lesions on nerve tissue. In this study, treatment process of the paresthesia of inferior alveolar nerve caused by radicular cyst which is remained asymptomatic for a long time in the left posterior mandible is presented in a 33 year-old male patient and it is evaluated in the light of current literature.Öğe Therapeutic effect of alendronate in an experimental temporomandibular joint osteoarthritis(Wiley, 2023) Acibadem, Elif; Keskinruzgar, Aydin; Bozdag, Zehra; Yavuz, Gunay YapiciBackgroundTemporomandibular joint osteoarthritis is a common degenerative joint disease. This disease negatively affects the daily life, speech and chewing functions of patients. ObjectiveThis study aimed to evaluate the effects of intra-articular injection of alendronate to osteoarthritis, which has a protective effect on bone and cartilage tissue and helps reduce inflammation in temporomandibular joint osteoarthritis. MethodsA total of 24 Wistar albino rats were used in the study. Rats were divided into four groups: study, saline, control and sham. In both saline and control groups, monosodium iodoacetate was injected intra-articularly to induce osteoarthritis. Alendronate was administered intra-articularly to the study group weekly for 4 weeks. In the saline group, saline was administered by intra-articular injection. At the end of the 12th week, all groups were sacrificed. Mandibular condyle tissues were examined histopathologically. ResultsAccording to the results, osteoarthritic changes in the control group were higher than those in the study group (p < .05). No significant reduction in osteoarthritic changes was observed in the saline group (p > .05). Significant osteoarthritis findings were observed in all groups compared with the sham group (p < .05). ConclusionIntra-articular injection of alendronate was found to have positive results on TMJ osteoarthritis. In addition, it was seen that alendronate has effects on reducing cartilage tissue degeneration and loss of matrix proteins.Öğe Ultrasonographic evaluation of the masseter muscle in patients with temporomandibular joint degeneration(Korean Acad Oral & Maxillofacial Radiology, 2023) Arikan, Busra; Dedeoglu, Numan; Keskinruzgar, AydinPurpose: Sonographic elastography can be used to evaluate the hardness of muscle tissue through the application of compression. Strain elastography gauges hardness through the comparison of echo sets before and after compression. This study utilized ultrasonography to measure the thickness and hardness of the masseter muscle in individuals with temporomandibular joint (TMJ) osteoarthritis.Materials and Methods: This study included 40 patients who presented with joint pain and were diagnosed with TMJ osteoarthritis via diagnostic cone-beam computed tomography, along with 40 healthy individuals. The thickness and hardness of each individual's masseter muscle were evaluated both at rest and at maximum bite using ultrasonography. The Mann-Whitney U test and the chi-square test were employed for statistical analysis, with the significance level set at P<0.05.Results: The mean thickness of the resting masseter muscle was 0.91 cm in patients with osteoarthritis, versus 1.00 cm in healthy individuals. The mean thickness of the masseter muscle at maximum bite was 1.28 cm in osteoarthritis patients and 1.36 cm in healthy individuals. The mean masseter elasticity index ratio at maximum bite was 4.51 in patients with osteoarthritis and 3.16 in healthy controls. Significant differences were observed between patients with osteoarthritis and healthy controls in both the masseter muscle thickness and the masseter elasticity index ratio, at rest and at maximum bite (P<0.05).Conclusion: The thickness of the masseter muscle in patients with TMJ osteoarthritis was less than that in healthy controls. Additionally, the hardness of the masseter muscle was greater in patients with TMJ osteoarthritis.Öğe Upward Migration of an Asymptomatic Lower Second Molar to the Coronoid Process(Lippincott Williams & Wilkins, 2016) Keskinruzgar, Aydin; Demirkol, Mehmet; Dedeoglu, Numan[Abstract Not Available]
