Publication Metadata only Re: A comparison of treatment effects of total arch distalization using modified C-palatal plate vs buccal miniscrews. Sang Kyu Lee; Noha H. Abbbas; Mohamed Bayome; Un-Bong Baik; Yoon-Ah Kook; Mihee Hong; Jae Hyun Park. The Angle Orthodontist. 2018; 88: 45-51(2019-09-01T00:00:00Z) YILMAZ, BERZA; ŞEKER, Elif Dilara; KURT, GÖKMEN; YILMAZ, BERZA; ŞEKER, ELIF DILARA; KURT, GÖKMENPublication Metadata only Comparison of Er:YAG laser and acid etching methods prior to lingual retainer application in vitro(2019-09-01T00:00:00Z) Kurt Biyiklioglu, Merve; YILMAZ, BERZA; YILMAZ, BERZAPublication Metadata only Laser-Aided Enamel Conditioning: A Comparison of Microleakage Under Brackets Following Different Aging Procedures(2019-11-01T00:00:00Z) Sen Yilmaz, Berza; Ok, Ufuk; Ramoglu, Sabri Ilhan; YILMAZ, BERZAObjective: To evaluate microleakage under the orthodontic adhesives applied following two version of erbium:yttrium aluminum garnet (Er:YAG) laser-aided enamel conditioning after thermal and thermomechanical simulators. Materials and Methods: A comparative analytical study based on metal braces bonded on the enamel of extracted teeth (n = 160) etched with acid, Er:YAG laser and Er:YAG laser with an X-Runner handpiece, and self-etch adhesives. An arch wire was ligatured to samples which were embedded in acrylic blocks by two with periodontal ligaments. The specimens were subdivided into two groups: those aged with thermal cycling and thermomechanical aging procedures. The samples were immersed in basic fuchsin solution (0.5%) for 24 h. Buccolingual sections were performed on the mesial and distal wings of the braces. The color penetration at the gingival and occlusal margins of the adhesive-bracket and enamel-adhesive was evaluated under a stereomicroscope. The median and mean values of microleakage in both groups were evaluated with Kruskal-Wallis and Mann-Whitney U tests (P < .05). Results: The highest microleakage was recorded in the gingival part of the samples aged with the thermomechanical aging procedure (P = .001). The amount of microleakage generally increased in the samples subjected to thermomechanical loading, but the only significant difference was recorded in the gingival part in each four different conditioning methods. Conclusion: Microleakage of the phosphoric acid-etched groups was recorded with lower values for both aging methods. Thermomechanical aging should be included to microleakage studies due to increased microleakage on gingival side for all etching groups.Publication Metadata only Skeletal, soft tissue, and airway changes following the alternate maxillary expansions and constrictions protocol(2015-01-01T00:00:00Z) Sen Yilmaz, Berza; Kucukkeles, Nazan; YILMAZ, BERZAObjective: To evaluate the skeletal, soft tissue, and airway effects of the alternate maxillary expansions and constrictions (Alt-RAMEC) protocol in prepubertal patients.Publication Metadata only Simultaneous Alveolar Cleft Closure and Dental Midline Correction With Curvilinear Intraoral Distraction(2014-05-01T00:00:00Z) Erverdi, Ahmet Nejat; Yilmaz, BERZA; Motro, Melih; GÖZNELİ, RİFAT; Ugurlu, Kemal; YILMAZ, BERZAThis article describes a new method that enables vector control during alveolar distraction osteogenesis in the treatment of a cleft palate patient. The patient presented with unilateral complete cleft lip and palate, and the alveolar part of the defect was covered by a mobile buccal flap. The distraction was performed by sliding the surgically released tooth segment with the help of an intraoral distractor over 1.5-mm stainless steel archwires held by metal crowns. This vector-controlled method enabled new bone and attached gingiva formation in harmony with the proper alveolar shape.Publication Open Access The Accuracy of Information about Orthodontics Available on the Internet(2018-12-01T00:00:00Z) Yilmaz, Borza Sen; YILMAZ, BERZAObjective: The aim of the present study was to evaluate the content of the informative websites related to orthodontic terms in Turkish and in English. Methods: Five different orthodontic terms ("orthodontic appliances (ortodontik aygıtlar)," "orthodontic braces (ortodontik braketler)," "orthodontic elastics (ortodontik elastikler)," "orthognathic surgery (ortognatik cerrahi)," and "orthodontic treatment (ortodontik tedavi)") both in Turkish and in English were searched using Google. There were 25 websites evaluated for each term. A total of 137 different websites were evaluated with three measurement tools: DISCERN (questionnaire, University of Oxford, 1999) (quality of information), LIDA (v1.2 Minervation, 2007) (accessibility, usability, and reliability), and AChecker (v0.1 ATutor, 2011) (accessibility). Results: The mean overall score of the quality of information was "good" for terms in Turkish and in English. The LIDA score was classified as "moderate" for terms in Turkish and in English. More accessibility errors were found on the Turkish websites than on the English counterparts. Most of the statistical evaluations between Turkish and English terms were insignificant. However, intragroup evaluation of the terms mostly showed significant differences. Conclusion: Accessibility, usability, and reliability; quality of information; and scores of access errors showed variations among Turkish and English sites. The collaboration of website designers and clinicians to increase the quality level of the websites is recommended.Publication Metadata only Is There a Relationship between Maxillary Sinus Findings and Skeletal Malocclusion?(2016-10-01T00:00:00Z) AKSAKALLI, SERTAÇ; YILMAZ, BERZA; Birlik, Muhammet; Dadaşlı, Ferit; Bölükbaşı, Esra; YILMAZ, BERZAObjective: No study has investigated the relationship between maxillary sinus findings and skeletal malocclusion based on conebeam computed tomography (CBCT). The aim of the present study was to determine the relationship between the frequency of sinus findings and patients- skeletal malocclusion classification.Publication Open Access Polymerization characteristics of colored compomers cured with different LED units(2019-02-01) Durmus, ZEHRA; Yilmaz, BERZA; Bakkal, MELTEM; Durmus, Ali; Ozalp, Serife; BAKKAL, MELTEM; YILMAZ, BERZA; ÖZDEMİR, ŞERİFEAim: Incomplete polymerization of a resin material used for dental restoration affects the properties of the restoration. We evaluated the structural and mechanical properties of three different colored compomers cured with three different LED units to observe the characteristic changes occurring in different matches. Methods: Polytetrafluoroethylene molds (5 mm in diameter and 2 mm in thickness) were used to prepare disk-shaped sample specimens. Nine sample groups (each of five specimens) were prepared, three each of different compomer resin colors (gold, berry, and silver). Samples were cured using three different LED units (Optima, VALO, and Demi Ultra), according to the manufacturers’ instructions. Microstructural properties of samples were characterized by determining the degree of curing using Fourier-transform infrared spectroscopy and by analyzing sample morphology under a scanning electron microscope. The Vickers hardness, compressive strength, and elastic modulus of the samples were measured to investigate their mechanical properties. Results: The degrees of curing decreased in the order of silver > berry > gold for all curing units. Conversely, gold compomers exhibited poorer mechanical values than the berry and silver counterparts. The Optima 10 unit yielded slightly higher degrees of curing than the other devices, followed by Demi Ultra and VALO light-curing units, respectively. Conclusion: The resin color affected the structural and mechanical properties of the compomers, possibly as a result of the complex interactions and relationships between the irradiation light and resin material, such as light absorbance and reflectance; thus, depending on the color as well as the curing protocol.Publication Metadata only Occurrence of Pneumatic Cavities Surrounding the Temporomandibular Joint(2015-07-01T00:00:00Z) Sen Yilmaz, Berza; Aksakalli, Sertac; Birlik, Muhammet; Dadasli, Ferit; Bolukbasi, Esra; Aytugar, Emre; YILMAZ, BERZAObjectives: The aim of this study was to investigate the occurrence, the location, and the characteristics of the pneumatic cavities (PCAs) surrounding the temporomandibular joint (TMJ) by using cone-beam computed tomography.Publication Metadata only Treatment effects evaluated with cone-beam computed tomography(2015-06-01T00:00:00Z) Sen Yilmaz, BERZA; YILMAZ, BERZA
