Öğe Angioleiomyoma of the gingiva: a report of two cases(Korean Acad Oral & Maxillofacial Surgery, 2016) Arpag, Osman Fatih; Damlar, Ibrahim; Kilic, Soydan; Altan, Ahmet; Tas, Zeynel Abidin; Ozgur, TumayLeiomyoma is a type of benign smooth muscle neoplasm that is a common neoplasm of the uterus and gastrointestinal tract but rarely affects the head and neck region and is especially unlikely to affect the oral cavity. The diagnosis of leiomyoma is mainly determined by histopathological studies due to variation in its clinical appearance and symptoms. In the present paper we report two rare cases of gingival angioleiomyoma in the posterior maxilla and mandible. After total excision, hematoxylin-eosin and smooth muscle actin staining confirmed the diagnosis of angioleimyoma.Öğe Applicability of the Demirjian method for dental assessment of southern Turkish children(Elsevier Sci Ltd, 2014) Celik, Salih; Zeren, Cem; Celikel, Adnan; Yengil, Erhan; Altan, AhmetAge-related legal problems are especially common in underdeveloped parts of Turkey. In terms of civil and criminal law, the ages from 13 years to 18 years are critical in our country. Estimation of age is a very significant in aspect of accordance with laws. The aims of this study were to evaluate the applicability and accuracy of the Demirjian technique for assessing southern Turkish children; to analyze the sexual dimorphism of dental age in the studied groups; and to define the relationship between the dental age and the degree of mineralization in mandibular permanent tooth in southern Turkish children. This study was performed using panoramic radiographs from 932 healthy southern Turkish children, 444 girls and 488 boys aged between 4 and 18 years. Statistical evaluations were performed using SPSS (Statistical Package for Social Sciences) for Windows 13.0 software. The mean difference between dental and chronological age was calculated for each age and sex group. The paired t-test was used to compare all data. The chi-square test was used for between-group comparisons of categorical variables. Continuous variables were tested for normality using the Kolmogorov-Smirnov test. Relationships between continuous variables were examined using Pearson's correlation coefficient. The same observer re-examined 700 teeth three months after the first examination. The results were evaluated with the intraclass correlation test and both measurements were statistically significantly similar with each other(R = 0.982, p = 0.0001). Dental age (DA) and chronological age (CA) were consistent for boys in the 16-16.9 age group and for girls in the 9-9.9 and 15-15.9 age groups. From this study, we can conclude that dental age varies across ethnic populations. Additionally, dental maturation varies across different regions of the same country. Because Demirjian's standards are not suitable for all age groups of southern Turkish children, a new table is necessary for evaluating this population. Future studies using multi-ethnic population data are needed to establish the international applicability of Demirjian's method. (C) 2014 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

Panoramic radiographs of 756 children (378 females, 378 males) aged between 5 and 14.99 years were examined by one observer. This retrospective study involved a contemporary southern Turkish population. The chronological ages of the subjects were divided into 10 groups. These 10 groups consisted of children of the following ages 5 and 14.99. Relationships between continuous variables were examined using Pearson's correlation coefficient. The paired t-test was used to compare all data according to gender and age groups. A p-value of less than 0.05 was considered significant for all statistical data. According to the results, a very high correlation was found for both girls (r(2) = 0.946) and for boys (r(2) = 0.940). Dental age (DA) and chronological age (CA) were consistent for girls in the four age groups (5-5.99, 6-6.99, 12-12.99, and 14-14.99) and for boys in the three age groups (5-5.99,13-13.99, 14-14.99). The maturity score of Willems' Belgian samples of the DA was applicable to seven groups of the southern Turkish children. The present study reports that Willems' method is more accurate for girls than for boys. (C) 2015 Elsevier Ltd and Faculty of Forensic and Legal Medicine.

A Nano-Indentation Study(W B Saunders Co-Elsevier Inc, 2016) Altan, Ahmet; Damlar, Ibrahim; Sahin, OsmanPurpose: The aim of this study was to compare the nano-hardness and elastic modulus of titanium and resorbable screws and determine whether resorbable screws could completely replace titanium screws. Materials and Methods: The mechanical properties (nano-hardness and decreased elastic modulus) of TriMed titanium, resorbable Inion CPS, and Synthes RapidSorb samples were measured using a nanoindentation technique. In this study, a Hysitron TriboIndenter TI 950 with a resolution less than 1 nN and a displacement resolution of 0.04 nm was used for the nano-indentation tests. The unloading segments of the nano-indentation curveswere analyzed using the method of Oliver and Pharr (J Mater Res 7: 1564, 1992). Results: Statistical analysis showed that the values of the elastic modulus and nano-hardness of the TriMed titanium screws were significantly higher than those of the resorbable Inion CPS and Synthes RapidSorb screws (P < .05). A statistical difference was not observed between the values of the elastic modulus and the nano-hardness of the Inion CPS and Synthes RapidSorb screws (P > .05). Conclusions: In this study, the resorbable screws were found to be soft and flexible compared with the titanium screw. According to the results of this nano-indentation study, resorbable and titanium screws cannot be used interchangeably. (C) 2016 American Association of Oral and Maxillofacial SurgeonsÖğe Cow's Milk Protein Allergy in Pediatric Dentistry(Mazandaran Univ Med Sci, 2019) Altan, Halenur; Cosgun, Alem; Altan, AhmetContext: Immunological reactions against proteins found in cow's milk (casein and whey proteins) are called Cow's Milk Protein Allergy (CMPA). CMPA has systemic as well as oral symptoms. Also, any casein-containing products used for preventive and therapeutic purposes in dentistry may trigger this allergy. The objective of this compilation is to reveal the importance of CMPA in dentistry by adhering to the literature. Evidence Acquisition: A literature search was done using PubMed, with focus on articles published in the last 10 years. Searched terms included the following: cow's milk protein allergy, child, pathogenesis, prevention, management, and dentistry. Results: Oral allergy syndrome and dental erosion caused by gastroesophageal reflux were observed in 40% of patients with CMPA that were detected by the dentists. Conclusions: Pediatric dentists should be aware of CMPA and pediatricians should be given support in definitive diagnosis of CMPA.Öğe Çukurova bölgesinin süpernümerer diş karakteristikleri : çok merkezli retrospektif bir çalışma(2014) Tatlı, Ufuk; Evlice, Burcu; Damlar, İbrahim; Arslanoğlu, Zeki; Altan, AhmetAMAÇ: Bu çalışmanın amacı, Çukurova bölgesinde gözlenen süpernümerer dişlere ait demografik özelliklerin incelenmesi ve güncel literatür ile kıyaslanmasıdır.GEREÇ VEYÖNTEM: Bu retrospektif çalışmada, Temmuz 2011-Temmuz 2013 tarihleri arasında çeşitli diş problemleri nedeniyle Çukurova Üniversitesi ve Mustafa KemalÜniversitesi Diş Hekimliği Fakültelerine başvuran 12735hastanın klinik ve radyografik verileri incelendi.

Age determination is important in terms of both laws and penalties in the legal process. Objectives: The aim of the present study was to compare the validity of the Demirjian and Willems methods in southern Turkish children. Methods: In this retrospective study, panoramic radiographs of 745 southern Turkish children (382 boys and 363 girls) aged between 4 and 15.99 years were examined by one investigator. According to Demirjian and Willems method, the mean difference between chronological and dental age was calculated for each sex and age group. The Wilcoxon test was used to compare all data. Statistical analysis was performed to test the validity of Demirjian and Willems methods by comparing the mean estimated and chronological age. Results: The Demirjian's method overestimated age with a mean accuracy of 0.832 in females and by 0.923 in males, while Willems method overestimated it by 0.202 in females and 0.434 in males. Conclusions: The dental age estimation by Willems method was found to be more accurate than Demirjian method in contemporary Turkish pediatric population.Öğe The effect of Hypericum Perforatum on wound healing of oral mucosa in diabetic rats(Istanbul Univ Press, Istanbul Univ Rectorate, 2018) Altan, Ahmet; Aras, Mutan Hamdi; Damlar, Ibrahim; Gokce, Hasan; Ozcan, Oguzhan; Alpaslan, CansuPurpose This study aims to investigate the histopathological and biochemical effects of the topical application of Hypericum perforatum on the healing of surgical wounds created in the oral mucosa of rats with experimentally induced diabetes mellitus. Materials and methods The study was carried out on 48 adult male Wistar albino rats. The animals were divided into two main groups as control and study groups. Two main groups were divided into three subgroups according to the sacrification days. All rats were given streptozotocin 60 mg/kg, after 72 hours, and those having blood glucose levels above 200 mg/dL were included in the study. Mucosal defects were created in the palatal area of the rats. H. perforatum oil was applied topically twice a day to the wounds of the rats in the study group. Animal were sacrificed on the 3rd, 7th and 10th days and samples taken from the palatal wounds were examined histologically and biochemically. Results On the 7th day, ulceration, necrosis, epithelialization, polymorphonuclear leucocytes and hydroxyproline variables showed statistically significant differences (p<0.05). Ulceration, necrosis and polymorphonuclear leukocytes values were higher in the control group, whereas epithelialization and hydroxyproline values were found to be higher in the H. perforatum group. Among 10th-day groups, there was only a statistically significant difference between the values of hydroxyproline, whereas H. perforatum-treated group showed high hydroxyproline levels (p<0.05). Conclusion Topically applied H. perforatum did not create any difference on the 3rd day, but it has positively affected the wound healing on the 7th and 10th days in diabetic rats.Öğe Hard tissue preparation prior to dental implant placement: A four-year retrospective study(Selçuk Üniversitesi, 2020) Arpağ, Osman Fatih; Altan, Ahmet; Damlar, İbrahimBackground: The purpose of this study was to investigateincidence for the requirements of hard tissue preparation prior todental implant placement.Methods: In this retrospective study, the records of 1086 patientswho referred to Mustafa Kemal University, Faculty of Dentistry,Periodontology and Oral and Maxillofacial Surgery clinics between2011 and 2015 were investigated.

Materyal ve Metod: Bu retrospektif çalışmada; 2010 ve 2013 yılları arasında Mustafa Kemal Üniversitesi Diş Hekimliği Fakültesi'ne, çeşitli sebeplerle başvuran 5227 hastanın (2865 kadın, 2362 erkek) panoramik radyografları tarandı. Mandibula ve maksillada gömülü kalmış dişler kaydedildi. Hastanın yaşı, cinsiyeti belirlenip; dişlerin gömülü kalma oranları, lokalizasyonları, gömülülük oranlarının cinsiyete göre dağılımları tespit edildi. Bulgular: Hastaların % 41,8'inde gömülü diş tespit edildi. Hastaların yaş dağılımı 18-80 arasında değişmekteydi. Gömülü kalma sıklığı sırasıyla mandibular 3. molar diş (% 64,7), maksiller 3. molar (% 30,9), maksiler kanin (% 3,1), mandibular premolar (%0,4), mandibular kanin (% 0,3), maksiler premolar (% 0,2), maksiler santral ve lateral kesiciler (% 0,2), mandibular santral ve lateral kesiciler (% 0,1), mandibular 1. ve 2. molarlar (% 0,07), maksiler 1. ve 2. molarlar (% 0,03) şeklindeydi. Sonuç: Hatay bölgesinde yaşayan bireylerde, yaşamın ilerleyen evrelerinde gömülü dişlerin genellikle çeşitli komplikasyonlar nedeniyle çekildiği ancak çok az bir kısmının herhangi bir semptoma neden olmadan gömülü kalmaya devam ettiği görüldü.Öğe Large dentigerous cyst in the maxillary sinus leading to diplopia and nasal obstruction : case repor(2015) Kara, Muhammed İsa; Yanık, Saim; Altan, Ahmet; Öznalçın, Onur; Ay, SinanDentijeröz kistler, çenelerin en yaygın gelişimsel odontojenik kistleridir. Sıklıkla erkeklerde görülür ve en çok maksillar kanin, mandibular üçüncü molar dişleri etkilerler. Süpernumere ve ektopik olarak sürmüş dişlerle ilişkili olabilirler. Bu makalede; maksiller sinüste ektopik üçüncü molar dişle ilişkili dentijeröz kistin tedavisini sunmayı amaçladık. 16 yaşında kadın hasta, yaklaşık altı aydır olan, sağ yanağının üzerinde ağrılı şişlik şikâyeti ile kliniğimize başvurdu. Tüm daimi dişler sağ üst üçüncü molar dışında mevcuttu. Ekstraoral muayenede yüzde asimetri, göz kürelerinin seviyelerinin eşit olmadığı görüldü. Radyografik muayenede, sol maksiller sinüste ektopik üçüncü molar dişle ilişkili kistik lezyon saptandı. Lokal anestezi altında marsüpyalizasyon yapıldı. Altı aylık takipten sonra genel anestezi ile cerrahi operasyonu yapıldı. Hastanın şikâyetlerinin operasyondan sonra tamamen geçtiği görüldü ve 3 yıllık takipte herhangi bir problemle karşılaşılmadı.Dentijeröz kistin istenmeyen etkilerinden kaçınabilmek için, sürmemiş dişlerin radyolojik incelemeleri dikkatle yapılmalıdır. Tedavi edilmeyen dentigeröz kistler büyük boyutlara ulaşabilir. Ayrıca odontojenik tümör oluşturma potansiyeline sahiptirlerÖğe LARGE DENTIGEROUS CYST IN THE MAXILLARY SINUS LEADING TO DIPLOPIA AND NASAL OBSTRUCTION: CASE REPORT(Istanbul Univ Press, Istanbul Univ Rectorate, 2015) Kara, M. Isa; Yanik, Saim; Altan, Ahmet; Oznalcin, Onur; Ay, SinanDentigerous cysts are the most common developmental odontogenic cyst of the jaws. They are more frequent in males and although most often affected teeth are maxillary canines and mandibular third molars, they may also be related with supernumerary or an ectopically erupted tooth. Our aim was to report the management of ectopic third molar tooth related with a dentigerous cyst in maxillary sinus. 16 years old girl referred to our clinic with a complaint of painful swelling over her right cheek since past six months. All permanent teeth were present except the right upper third molar. External examination showed that the face was gently asymmetrical; levels of eye globes were abnormal. Radiographic examination revealed a cystic lesion related with ectopic third molar which located in the roof of the left maxillary sinus. Under local anesthesia, hard drain was inserted into the hole and the cystic pressure was decreased. After the six month of follow-up, the operation was performed under general anesthesia. The patient's symptoms were resolved completely after surgery and remained symptom-free for over a postoperative follow-up period of 3 year. To avoid unwanted effects of a dentigerous cyst, unerupted tooth should be observed with radiographic imaging. Some untreated dentigerous cysts may grow large and have a potential to develop into an odontogenic tumor.Öğe Maksillada fibröz displazi : iki olgu sunumu(2015) Altan, Ahmet; Damlar, İbrahim; Kılıç, Soydan; Turgay, Berk; Taş, Zeynel AbidinFibröz displazi genellikle çocuklarda ve ergenlerde görülen; kemiğin gelişimsel, yavaş büyüyen, fibroosseöz benign bir lezyonudur. Monostotik ve poliostotik olmak üzere iki klinik formu vardır. Lezyon içindeki kemik oluşumunda artışla birlikte 'buzlu cam' veya 'portakal kabuğu' olarak adlandırılan radyografik görüntü oluşur. Bu makalede klinik, radyografik ve histopatolojik bulgularla tanı konulmuş iki fibröz displazi olgusu sunulmuştur.19 yaşında erkek hasta, 3 aydan beri var olan sağ üst bölgede şişlik şikayetiyle kliniğimize başvurdu. Klinik muayene sonucunda üst çene anterior bölgede vestübüle ekspansiyon gösteren asemptomatik bir lezyon tespit edildi. Lokal anestezi altında kontur düzeltmesi yapılarak fonksiyonel ve estetik sorunlar ortadan kaldırıldı.56 yaşındaki bayan hasta sağ maksillada şişlik şikayetiyle kliniğimize başvurdu. Ağız içi muayenede sağ maksillada vestibüle ve palatinale ekspansiyon gösteren bir şişlik görüldü. İnsizyonel biyopsi sonucunda fibröz displazi tanısı konuldu. İleri yaştaki hastada, büyük boyutlardaki asemptomatik lezyonun aylık kontrollerle takip edilmesine karar verildi.Çene kemiklerinde fibröz displazi nadir görülen bir durumdur. Diğer benign ve malign kemik bozukluklardan ayırt edilmesi zor olabilir. Malign transformasyon son derece nadirdir ve daha çok poliostotik tipte görülür. Bu nedenle takibi önemlidir.Öğe Management of obstructive sleep apnea in a Treacher Collins syndrome patient using distraction osteogenesis of the mandible(Korean Acad Oral & Maxillofacial Surgery, 2016) Damlar, Ibrahim; Altan, Ahmet; Turgay, Berk; Kilic, SoydanIn this study, we present the surgical treatment of obstructive sleep apnea in a child with Treacher Collins syndrome. A 10-year-old girl with a past history of Treacher Collins syndrome presented to our clinic with her parents for respiratory distress and insomnia. The patient was referred to a sleep laboratory where she was diagnosed with obstructive sleep apnea, which was a consequence of her Treacher Collins syndrome. The patient underwent mandibular distraction osteogenesis under general anesthesia. The mandible was expanded by 15 mm using internal bilateral distractors. After distraction osteogenesis, the patient's respiratory problems resolved, and she was able to sleep comfortably. Distraction osteogenesis was an effective method of advancing the mandible, increasing the upper airway space and ultimately preventing obstructive sleep apnea syndrome in patients with Treacher Collins syndrome.Öğe Oral Angioleiomyoma of the Lower Lip: A Case Report(Derman Medical Publ, 2013) Damlar, Ibrahim; Kisa, Halil Ibrahim; Tatli, Ufuk; Altan, Ahmet; Hakverdi, SibelLeiomyoma is a benign smooth muscle tumor that occurs most frequently in the uterine myometrium, gastrointestinal tract, skin and lower extremities. Leiomyoma rarely affects the oral cavity. Angioleiomyoma (vascular leiomyoma) is a histological subtype of the leiomyoma. The diagnosis is commonly determined by histopathological studies. This case report shows a 35-year-old male patient with a lesion of the lower lip. After surgical excision, hematoxylin-eosin and smooth muscle actin staining confirmed the diagnosis of angioleiomyoma.Öğe Oral kavitenin reaktif lezyonları :147 vaka üzerine rekrospektif bir çalışma(2014) Altan, Ahmet; Yanık, Saim; Damlar, İbrahim; Arpağ, Osman Fatih; Demirkol, MehmetAmaç: Ağız mukozasının çok katlı yassı epiteli patojenik faktörlere karşı koruyucu görev yapar.

Sonuç: Oral reaktif lezyonlar sıklıkla kadınlarda görülmektedir ve en çok diş etini etkilemektedir. Yaptığımız çalışma en çok rastlanan reaktif lezyonun periferal göstermektedirÖğe Retrospective Investigation Of the Prevalence of Impacted Teeth in Hatay(Cukurova Univ, Fac Medicine, 2014) Damlar, Ibrahim; Altan, Ahmet; Tatli, Ufuk; Arpag, Osman FatihPurpose: The purpose of this study were to examine localization, the prevalence of impacted permanent teeth and to perform the distributions according to sex and jaws in Hatay population. Material and Methods: In this retrospective study, up to 5227 orthopantomograms of the patients (2865 women, 2362 men) who were referred to Mustafa Kemal University, Faculty of Dentistry, Hatay from December 2010 to June 2013 were examined. Data including the age, gender, localization were evaluated by statistical tests. Results: There were 2187 (% 41,8) patients having impacted teeth. The age of the patients ranged from 18 to 80. Among the impacted teeth, mandibular third molars were the most common (% 64,7), followed by maxillary third molars (% 30,9), maxillary canines (% 3,1), mandibular premolars (% 0,4), mandibular canines (% 0,3), maxillary premolars (% 0,2), maxillary central and lateral incisors (% 0,2), mandibular central and lateral incisors (% 0,1), mandibular first and second molarlars (% 0,07), maxillary first and second molars (% 0,03) Conclusion: In later stages of the people who lives in Hatay's life, due to complications of impacted teeth usually extracted. The impacted teeth were seen without causing any symptoms in a small part of population.Öğe Santral dev hücreli granülomanın iliak greft ve hareketli yer tutucu aparey ile rehabilitasyonu : olgu sunumu(2014) Damlar, İbrahim; Altan, Ahmet; Yanık, Saim; Arslanoğlu, Zeki; Çevik, CengizAmaç: Santral dev hücreli granüloma sıklıkla mandibula ve maksillada lokalize olan, non-odontojenik patolojik bir lezyondur. Etiyolojisi tam olarak bilinmemektedir. Lezyonun cerrahi olarak uzaklaştırılması en çok uygulanan tedavi yöntemidir. Amacımız bu vakada santral dev hücreli granülomanın iliak greft ve hareketli yer tutucu aparey kullanılarak rehabilitasyonunu rapor etmektir. Vaka raporu: 10 yaşındaki erkek hasta kliniğimize mandibula anterior sol bölgede şişlik şikayetiyle başvurdu. Alınan anamnezde, şikayetin olduğu bölgeye yaklaşık 1 yıl önce cerrahi bir müdahale yapıldığı, fakat şişliğin altı ay önce tekrar oluştuğu öğrenildi. Genel anestezi altında lezyon çıkartıldı. Mandibular sol santral, lateral, kanin ve birinci premolar dişler çekildi. Mandibulada oluşan defekt iliak greftle onarıldı. Çıkarılan kitlenin histopatolojik incelemesi yapıldı ve santral dev hücreli granülom tanısı konuldu. Operasyon sonrası yapılan 12 aylık takipte herhangi bir problemle karşılaşılmadı. Daha sonra hastaya hareketli yer tutucu bir aparey yapıldı. Sonuç: Literatürde santral dev hücreli granülom gibi agresif lezyonların %72 rekürens oranı olduğu görülmektedir. Rekürens gösteren vakalarda kortikostreoid enjeksiyonu, sistemik kalsitonin uygulaması gibi konservatif yöntemlerin başarısı kesin değildir. Cerrahi tedavi çene kemiklerinde major defektlere neden olabilir ve fasiyal konturu bozabilir. Böyle bir durumda defektin iliak greftle tamiri estetik problemleri çözecektir ve protezle rehabilitasyon imkanı sunacaktır.Öğe To what extent does hyaluronic acid affect healing of xenografts? A histomorphometric study in a rabbit model(Univ Sao Paulo Fac Odontologia Bauru, 2018) Arpag, Osman Fatih; Damlar, Ibrahim; Altan, Ahmet; Tatli, Ufuk; Gunay, AhmetAmong the many graft materials that have been used for the treatment of bone defects in oral and maxillofacial regions is xenograft. To improve osteoconductive effects of xenografts, they have been combined with various biocompatible materials, such as hyaluronic acid and bone morphogenetic protein. Objective: To determine bone-healing capacity of high molecular weight hyaluronic acid (HA) combined with xenograft in rabbit calvarial bone defects. Material and methods: Ten adult male New Zealand rabbits (mean weight 3 kg) were included in the study. Three 6-mm-diameter bicortical cranial defects were created on calvarial bone of all rabbits. These defects were filled as follows: a) xenograft; b) HA+xenograft; c) autograft. One month after the first operation, rabbits were sacrificed. Specimens were evaluated histomorphometrically. Results: Considering multiple comparisons, differences regarding new bone were statistically significant between all groups (p<0.05). The volume of residual graft was significantly decreased in HA group compared to xenograft group (p=0.035). Marrow space, trabecular thickness (TbTh), trabecular width (TbWi), trabecular separation (TbSp), and number of node: number of terminus (NNd:NTm) in the autograft group were significantly better than xenograft and HA groups (p<0.05). However, regarding marrow space, TbTh, TbWi, TbSp, and NNd: NTm values, xenograft and HA groups showed similar results and the difference were not significant (p>0.05). Conclusion: These results support that high molecular weight hyaluronic acid could contribute to the healing of xenograft by improving the percentage of new bone formation and reducing the percentage of residual graft. However, HA did not significantly affect the quality of newly formed bone assessed by microarchitectural parameters.
