The desmoplastic variant of ameloblastoma (DA) is characterized by unique histological and radiographic features. It is histologically characterized by an abundance of densely collagenous stroma with small nests and strands of likely compressed odontogenic epithelium. Although radiographic examination of ameloblastomas usually reveals unilocular or multilocular radiolucency, DA may appear as a mixed radiopaque-radiolucent lesion. In this case report, a 68-year-old man who had a complaint of a mass in his right mental region is presented. The patient was unable to wear his prothesis because of an underlying swelling. An incisional biopsy was performed. Microscopic examination of the surgical specimen revealed large epithelial islands of ameloblast-like cells within increased, dense, collagenous desmoplastic stroma. Histopathologically, it was diagnosed as DA. Under local anesthesia, the lesion was enucleated. There was no recurrence after 32 months of follow-up.

Amaç Odontomalar çenelerde en sık görülen odontojenik kökenli iyi huylu tümörlerdir. Yavaş büyürler ve agresif davranış göstermezler. Genellikle asemptomatiktirler ve sıklıkla rutin radyografi sırasında bulunurlar. Kompleks ve kompaund odontoma olarak ikiye ayrılmaktadır. Bu vaka serisinde 8’i komplex 14'ü kompaund, toplam 22 odontoma vakasının cerrahi tedavisinin anlatılması amaçlanmıştır. Olgular Sunumu Yaş aralığı 10-34 arası olan 14’ü kadın 8’i erkek toplam 22 hasta, bölümümüzde gerekli klinik ve radyolojik muayenelerden sonra cerrahi olarak opere edilmiştir. Çıkarılan dokuların histopatalojilerinin, radyolojik ve klinik bulgularla değerlendirilmesi ile 8’inin komplex 14’ünün kompound odontoma olduğu tespit edilmiştir. Bazı vakalarda odontoma ile birlikte gömülü diş alınırken bazı vakalarda diş sürmesinin takibi amacıyla veya çene fraktürü riski sebebiyle etken gömülü dişler bırakılmıştır. İyileşme süresince hastalarda herhangi bir komplikasyon görülmemiştir. Sonuç Odontomalar genellikle asemptomatik görüldükleri için hastaların diş hekimlerine rutin kontrollere gelmeleri, erken teşhiste çok önemlidir. Erken teşhis ile morbidite ve maliyet azaltılabilir.

Background: The simple explanation of burnout syndrome is exhaustion from work and work-related factors. It is more common in work that requires face-to-face contact with people, such as dentists. In this study, we researched the burnout levels of dentists working in Turkey and evaluated them according to gender, title, place of work and experience. Methods: Burnout scores were determined by the Copenhagen Burnout Inventory. This questionnaire was delivered to dentists online through various social media applications. We analyzed data via SigmaPlot Software. Results: The answers of a total of 477 dentists were considered valid. We observed that 73,5% of them had high burnout scores. A statistically significant difference was found in the evaluations according to the title and workplace. Experience and gender do not statistically affect burnout scores. Conclusion: It has been observed that dentists working in Turkey are more likely to face burnout syndrome at high levels. It has been predicted that patient burden may be closely related to burnout syndrome.

The aim of this in vitro study was to compare the efficacy of sodium-tri-metaphosphate-treated varnish containing eggshell and membrane powder and bioactive glass varnish with fluoride varnish in preventing erosion. Two windows were created on the buccal surface of 72 molars for the erosion cycle. One of the windows was treated with fluoride varnish [(FV, Metroberry, Imicryl), varnish containing STMP-treated eggshell and membrane powder (EPV, BioViera, Imicryl) and bioactive glass varnish (BAG, Polimo, Imicryl)] while the other window was used as control. Acidic syrup (Atarax) was applied 3 times a day and acidic drink (Coca Cola) 4 times a day for 5 days. The samples were analyzed by SEM (n = 1), ATR-FTIR (n = 6) and Vicker’s hardness (n = 5). Data were analyzed by one-way ANOVA and post hoc Tukey test. The protective effects of the varnishes were observed in the SEM images obtained. There was a difference between the FV and EPV groups in the 875 cm⁻¹ v₂ CO₃ ⁻² peak spectrum and microhardness values (p < 0.05). There was a difference between FV and FV-C in the carbonate v₂ band in the acidic beverage demineralised varnish groups (p < 0.05). Other band areas and CO₃ ⁻² /PO₄ ⁻³ ratios of the varnish areas against the erosion and control areas showed similar results (p > 0.05). Microhardness analyses showed that the BAG group demineralized with acidic syrup and the FV group demineralized with acidic drink were similar to the control group (p > 0.05). The varnishes tested in our study showed a similar protective effect against erosion as fluoride varnishes.

Background: The surface properties of dental and orthopedic implants are directly related to their osseointegration rate. Coating and/or modifying the implant surface might reduce the time of healing. In this study, we aimed to examine the effects of a hybrid surface consisting of a brushite surface coating and cross-linked water-soluble eggshell membrane protein ...
