An In Vitro Comparison of Different Diagnostic Methods in Detection of Residual Dentinal Caries


Makale | 2010 | Hindawi Publishing Corporation

The aim of this study was to investigate the efficiency of different diagnostic methods in detection of residual dentinal caries in excavated cavities. Fifty extracted molar with deep dentinal carious lesions were excavated using a slow-speed handpiece. All cavities were assessed by laser fluorescence(LF) device, electronic caries monitor(ECM), and caries detector dye(CDD) by three independent observers blindly. The measurements were repeated after two weeks. Specimens containing dentin slices 150 μm in thickness were prepared for histological analyses. The existence and absence of carious dentin was determined using a lig . . .htmicroscope. The average intraobserver accuracy was 1.00 (perfect agreement) for CDD, 0.86 (excellent agreement) for ECM, and 0.50 (good agreement) for LF. The average interobserver accuracy values were 0.92 (excellent agreement), (0.36 marginal agreement) and 0.48 (good agreement), for CDD, ECM, and LF, respectively. The average specificity was 0.60 for CDD, 73% for ECM, and 0.50 for LF. The average sensitivity was 0.55 for CDD, 0.85 for LF, and 0.47 for ECM. The average accuracy values were 0.53, 0.51, and 0.81 for CDD, ECM, and LF, respectively. LF had the greatest sensitivity and accuracy values of any of the methods tested. As a conclusion, LF device is appeared to most reliable method in detection of remain caries in cavity. However, because of its technical sensitivity it may susceptible to variations in measurements. To pay attention to the rule of usage and repeated measurements can minimize such variations in clinical practice. It was concluded that LF is an improvement on the currently available aids for residual caries detection Daha fazlası Daha az

Influence of soft drinks on dental enamel: An in vitro study


Makale | 2013 | Wolters Kluwer Health

This in vitro study was to evaluate the erosive potential of four soft drinks at different times on bovine teeth by profilometry. Bovine incisors buccal side was sectioned with a diamond saw and a total of 100 enamel blocks were prepared (8 × 4 × 0.5 mm). Five specimens each were exposed to 60 ml of soft drinks (Sprite, Coca Cola, Cappy-orange and Ayran) for 15, 30, 60, 120 and 180 minutes in a continuously vibrating soft drinks bath in a beaker at room temperature. Surface loss of the specimens was determined with a profilometry. The data were analyzed by two-way analysis of variance and Tukey HSD test. Loss of enamel was observed . . .in Coca Cola, Cappy and Sprite groups. Coca Cola was significantly higher erosive potential in 180 minutes than other soft drinks (p < 0.05). Ayran was no sign of erosive potential in all time. It can be concluded that the composition of the beverages had a significant effect on dental erosion, so consumption of Ayran can be advised Daha fazlası Daha az

Treatments of horizontal root fractures: four case reports


Makale | 2013 | Wolters Kluwer Health

Horizontal root fractures are rare in comparison to other types of injuries and the reported prevalence in the literature is between 0.5% and 7%. The treatment and prognosis of root fractures depend on many variables, the most important being the length of time between trauma and treatment, degree of dislocation and mobility, site of fracture, fixation period, stage of root development, age of patient, and quality of treatment. The ideal healing type is hard tissue healing. The aim of these case reports is to present four different patients who had horizontal root fractures of immature permanent teeth treated by repositi . . .oning and fixation with good healing. Patients were referred to our clinic with a complaint of mobility and tenderness in their upper central incisors as a result of an orofacial injury. As a result of radiographical examination, horizontal fractures were diagnosed on the roots. Teeth were repositioned and rigid fixation was applied. Splints were retained for about 12 weeks. After splints were removed, patients were scheduled for follow‑up visits at 3 month intervals. After long‑term clinical and radiographical follow‑up, all teeth presented positive response to electrical pulp tests, suggesting a repair of root fractures. These immature teeth showed radiographic evidence of continued root development and normal color and mobility, and no pain was observed in horizontal and vertical percussion tests. Patients reported no discomfort with their teeth. Using splints without any further treatment was found to be successful in the presence of suitable conditions for the treatment of horizontal root fractures Daha fazlası Daha az

Ehlers-danlos sendromu : olgu sunumu


Makale | 2009 | Selçuk Üniversitesi Diş Hekimliği Fakültesi

Ehlers Danlos Syndrome (EDS) is a connective tissue disease that has effect on the structure and function of collagen. Collagen is a fibrous protein that is one of the main building structures of connective tissues such as skin, tendon, bone and cartilage. Connective tissue requires all type of collagen to function correctly. People with EDS may show symptoms such as skin hyperelasticity, joint hypermobility, increased tendency to bruise and abnormal scarring. Dental findings have been reported with some types of EDS. This case report describes the dental findings of a patient (10, c?) who applied to Selçuk University Department . . .of Pediatric Dentistry with dental caries and mobility. According to his medical history he was born at month 7 of the pregnancy. He had a history of easy bruising and scarring after minimal trauma and presented a soft and hyperextensible skin. In addition, he had atrophic paper scars on the face, elbows, knees and shins; hypertelorizm on the face, ecchymosis on the lower legs and generalized joint laxity. Intraoral examination revealed pigmentation at gingival tissues, mobility at mandibular lateral and central incisors and supernumerary teeth in the area of left maxilla. Based on these findings the patient’s profile was consistent with classical type EDS. In this report a case with EDS is presented and also the clinical approach to his dental problems is emphasized Daha fazlası Daha az

Fiberle güçlendirilmiş kompozit rezin köprü restorasyonu


Makale | 2011 | Türkiye Klinikleri

Çocuk ve adolesanlarda konjenital olarak eksik veya travma nedeni ile kaybedilmiş daimi kesici dişlerden kaynaklanan problemlerin tedavisi için farklı yaklaşımlar mevcuttur. Bu olgu raporunda, alt ön keser dişleri konjenital olarak eksik olan hastaya uygulanan polietilen fiber ile güçlendirilmiş rezin tutuculu köprü sunumu amaçlanmıştır. On iki yaşındaki kız çoğuğu, bölümümüze diş eksikliğine bağlı estetik problem nedeni ile getirildi. Ağız içi ve radyolojik muayenesinden alt ön keser dişlerinin konjenital olarak eksik olduğu belirlendi. Komşu yan keser dişler bu bölgeye diastemalı olarak yerleştikleri için mevcut boşluk, köprü yapı . . .mına uygun değildi. Kısa süreli ortodontik tedavi ile köprü yapımı planlanan boşluk kısmen yeterli hale getirildi. Kompozit materyalden hazırlanan köprü gövdesi mevcut boşluğa, fiber ile güçlendirilmiş kompozit rezin materyal yardımıyla sabittendi. Hastanın 24 ay sonraki kontrolünde herhangi bir sorunun olmadığı görüldü. Minimal invaziv yaklaşımla uygulanan fiber ile güçlendirilmiş kompozit rezin köprülerin, gelişim dönemindeki hastalar için estetik, fonksiyon ve fonasyon kayıplarının düzeltilmesinde kullanılan ekonomik bir tedavi seçeneği olduğunu düşünmekteyiz. Different treatment alternatives are considered for the rehabilitation of congenitally or traumatically missing permanent incisors in young children and adolescents. The purpose of this case report is to present an example of polyethylene fiber-reinforced composite resin bonded bridge. A 12-year-old girl, was referred to our clinic with complaints regarding aesthetics. The screening procedure revealed congenitally missing lower central incisors short term orthodontic treatment provided the necessary space for prothetic restoration was relatively opened to a built bridge. Fiber reinforced composite resin material was used to bond the composite bridge restoring the created space. Follow-up examination after 24 months, revealed stability with the absence of problems. Fiber reinforced composite resin bridge applications with minimal invasive approach may be an economical treatment alternative for rehabilitation of aesthetics, function and phonetics in young children and adolescents Daha fazlası Daha az
