“…After this fatigue phase, the specimens were placed in the Instron Universal Testing machine (E3366, Instron, MA, America). Each tooth was loaded at the central fossa at 135° from the tooth long axis to simulate a maximum bending motion of the tooth at buccal cervical areas [8]. A continuous compressive force was applied with a 2-mm spherical crosshead at 1 mm/min until failure occurred, which was de ned as a 25% drop in the applied force [24] ( Fig.…”

Background: This study aims to compare the percentage of dentin removed, instrumentation efficacy, root canal filling and load at fracture between contracted endodontic cavities, and traditional endodontic cavities on root canal therapy in premolars. Methods: Forty extracted intact human first premolars were imaged with micro-CT and randomly assigned to the contracted endodontic cavity (CEC) or traditional endodontic cavity (TEC) groups. CEC was prepared with the aid of a 3D-printed template, canals were prepared with a 0.04 taper M-Two rotary instrument, and cavities were restored with resin. Specimens were loaded to fracture in an Instron Universal Testing Machine after a fatigue phase. The data were analyzed by the independent samples T test and Mann-Whitney U test, appropriate post hoc tests. Results: In the premolars tested in vitro, the percentage of dentin removed in the premolars with two dental roots in the CEC group (3.85% ± 0.42%) was significantly smaller (P < 0.05) than in the TEC group (4.94% ± 0.5%). The untouched canal wall (UCW) after instrumentation for TECs (16.43% ± 6.56%) was significantly lower (P< .05) than the UCW (24.42% ± 9.19%) for CECs in single-rooted premolars. No significant differences were observed in the increased canal volume and surface areas in premolars between the TEC and CEC groups (P > 0.05). CECs conserved coronal dentin in premolars with two dental roots but no impact on the instrument efficacy. There were no differences between the CEC groups and the TEC groups in the percentage of filling material and voids (P > 0.05). In addition, the mean load at failure of premolars did not significantly differ between the CEC and TEC groups and there was no significant difference in the type of fracture (P > 0.05). Conclusion: The results of this study suggest that CEC could not improve the fracture resistance of the endodontically treated premolars. The instrumentation efficacy and the percentage of filling material did not significantly differ between CECs and TECs in premolars.

Ö ÖZ ZE ET T Toplumda yüksek oranda gözlemlenen temporomandibuler eklem (TME) rahatsızlıkları çene, boyun ve baş ağrıları, eklem sesleri gibi pek çok semptomla bireylerin yaşam kalitesini düşürmek-tedir. Bu rahatsızlıklar tedavi edilmediği takdirde ilerlemekte ve TME'de kalıcı hasara sebep olabilmektedir. TME rahatsızlıkları için pek çok tedavi yöntemi bildirilmiştir. Bu tedavi yöntemleri geri dönüşümlü (noninvaziv) ve geri dönüşümsüz (invaziv) tedaviler olmak üzere ikiye ayrılmıştır. Geri dönüşümlü tedaviler arasında bilgilendirme yöntemi, fizik tedavi yöntemleri, farmakolojik tedavi, psikiyatrik destek tedavisi ve oklüzal splint tedavileri yer alır iken; geri dönüşümsüz tedaviler oklüzal uyumlama ve cerrahi girişimleri içermektedir. TME rahatsızlıklarında geri dönüşümsüz tedavilerden önce daha konservatif yöntemler olan geri dönüşümlü tedaviler denenmesi temel prensiptir. Tavsiye edilen tedavi yöntemlerinin etkinliklerini araştırmak amacıyla pek çok çalışma yapılmıştır. Bununla birlikte, tedavi etmede ya da semptomları azaltmada hangi tedavi yönteminin ya da hangi splint tipinin daha etkin olduğuna dair kesin bir kanıt mevcut değildir. Etki mekanizmaları ve tedavi başarıları tartışmalı olmasına rağmen, TME rahatsızlıkları tedavisinde en çok kullanılan yöntem oklüzal splint tedavisidir. Diş hekimliğinde her biri farklı özel durumlar için olmak üzere birçok oklüzal splint kullanılmaktadır. Splint endikasyonları TME inflamasyonu, eklem içi dü-zensizlik, cerrahi sonrası tedavi, hipertonik yüz kasları, diş sıkma ve gıcırdatma olarak belirtilmektedir. Bu çalışmada, oklüzal splint çeşitleri ele alınmış ve güncel literatür bilgisine dayanılarak TME rahatsızlıklarının tedavisinde kullanılan geri dönüşümlü yöntemlerin etkinliklerinin değer-lendirilmesi amaçlanmıştır.A An na ah ht ta ar r K Ke el li im me el le er r: : Temporomandibuler eklem bozuklukları; oklüzal splintler A AB BS ST TR RA AC CT T Temporomandibular joint (TMJ) disorders are highly prevalent in the community and reduces the quality of life with many symptoms such as jaw and neck pain, headache and joint sounds. These disorders progress when they are not treated and may cause permanent damage to the TMJ. Many treatment modalities have been reported for TMJ disorders. These treatment methods are divided into two as non-invasive treatments and invasive treatments. Non-invasive treatments include informative methods, physical therapy, pharmacological treatment, psychiatric support therapy and occlusal splint therapies and invasive treatments include occlusal adjustment and surgical interventions. Non-invasive treatments, which are more conservative methods should be employed before invasive treatments for TMJ disorders. Many studies have been conducted to investigate the effectiveness of recommended treatment modalities. However, there is no definitive evidence of which treatment method or splint type is more effective in treating or reducing symptoms. Although the mechanisms of influence and treatment success are controversial, the most common method of tre...

Despite the new ideas were inspired in medical treatment by the rapid advancement of three-dimensional (3D) printing technology, there is still rare research work reported on 3D printing of coronary arteries being documented in the literature. In this work, the application value of 3D printing technology in the treatment of cardiovascular diseases has been explored via comparison study between the 3D printed vascular solid model and the computer aided design (CAD) model. In this paper, a new framework is proposed to achieve a 3D printing vascular model with high simulation. e patient-speci c 3D reconstruction of the coronary arteries is performed by the detailed morphological information abstracted from the contour of the vessel lumen. In the process of reconstruction which has 5 steps, the morphological details of the contour view of the vessel lumen are merged along with the curvature and length information provided by the coronary angiography. After comparing with the diameter of the narrow section and the diameter of the normal section in CAD models and 3D printing model, it can be concluded that there is a high correlation between the diameter of vascular stenosis measured in 3D printing models and computer aided design models. e 3D printing model has high-modeling ability and high precision, which can represent the original coronary artery appearance accurately. It can be adapted for prevascularization planning to support doctors in determining the surgical procedures.
