This study was conducted to evaluate the effects of ethylenediaminetetraacetic acid (EDTA), Irritrol, and QMix solutions used with manual irrigation and diode and erbium, chromium-doped yttrium, scandium, gallium, and garnet (Er,Cr:YSGG) laser activation on the bonding ability of sealer to the intraradicular dentin. The root canals of 90 mandibular incisors were instrumented, and the teeth were allocated randomly to nine groups (n = 10/group) receiving final irrigation with different irrigation solutions (EDTA, Irritrol, and QMix) and irrigant activation techniques (manual, diode laser, and Er,Cr:YSGG laser). Following endodontic filling, three sections of 1-mm thickness were obtained from the middle third of each root. The root filling was subjected to a push-out test to examine the bond strength of the sealer to dentin. The test data were examined using analysis of variance with a significance level of ɑ < .05. Failure modes were determined by stereomicroscopy, and the surface characteristics of dentin were observed by scanning electron microscopy. Irritrol showed less push-out bond strength than did the other solutions in the Er,Cr:YSGG laser groups (p < .05). In the diode laser groups, QMix provided greater adhesion than did Irritrol (p < .05). The activation of QMix with the Er,Cr:YSGG laser increased the bond strength more than did manual irrigation (p < .05). No other significant difference was observed between other comparison pairs (p > .05). QMix provided adhesion superior to that of Irritrol when activated with diode and Er,Cr:YSGG lasers. Er,Cr: YSGG laser activation increased the adhesion of filling material with QMix irrigation.
ÖZDens invaginatus ve dens evaginatus gelişimsel dental anomalilerdir. Aynı dişte çift dens evaginatus ve dens invaginatus son derece nadirdir. Bu makalenin amacı maksiller lateral kesici dişlerdeki çift dens invaginatus ve dens evaginatuslu iki vakayı sunmaktır. Detaylı klinik ve radyografik muayene bu tür abnormaliteleri belirlemek için önemlidir. Diş hekimlerinin dens invaginatus ve dens evaginatus'un klinik ve radyografik bulguları hakkındaki farkındalığı erken tanı ve tedavi için önemlidir. ANAHTAR KELİMELER: Dens invaginatus, dens evaginatus, talon cusp, çift, anomali
Avulsion is the completely taking out of the tooth from the dental socket; and replantation is replacing the teeth which have been completely avulsed by trauma. Traumatic injuries to permanent anterior teeth are common during childhood and 0.5-16 % of the 7 to 10 years age group experience tooth avulsion. The prognosis of replanted teeth depends on several factor, the most important being the length of extra-oral dry time. The most preferable management for the avulsed tooth is immediate replantation, within 20-30 min after injury or keeping in storage media until dental visit.The purpose of this case report, is replantation technique which used in the treatment of an avulsive tooth case. Case was avulsed right mandibulary permanent lateral incisor of 8 years old male patient suffering from a traumatic injury who came to the clinic 16 h later from injury.Although replantation of avulsed permanent teeth are widely accepted treatment approach, the long-term prognosis of replanted teeth are still contraversial.Key Words: Avulsion, delayed replantation, dental trauma ÖZET Travmatik yaralanma sonras›nda dişin alveoler soketten tamamen ç›kmas›na avulsiyon, travma sonucu total olarak alveoler soketten ç›km›ş olan dişin tekrar yerine yerleştirilmesine replantasyon ad› verilmektedir. Ön grup dişlerin travmatik yaralanmalar› genel olarak 7 ila 10 yaş grubu çocuklarda % 0.5-16 oran›nda görülmektedir. Replante edilmiş dişin prognozu birkaç faktöre bağl›d›r, en önemli faktör dişin ağ›z d›ş›nda kald›ğ› süre ve sakland›ğ› ortamd›r. Avülse dişin en uygun tedavisi yaralanmadan hemen sonra 20-30 dak içerisinde yap›lan erken replantasyon ya da diş hekimine gelene kadar dişin uygun saklama solüs-yonunda saklanmas›d›r.Bu vaka raporu travmatik yaralanma sonras›nda sağ alt lateral dişinin avülse olmas› nedeniyle 16 saat sonra kliniğe gelen 8 yaş›ndaki erkek hastan›n replantasyon tekniğini sunmaktad›r.Avulse olmuş daimi dişin replantasyonu büyük ölçüde kabul gören ilerleme kaydetmesine rağmen replante edilmiş dişin uzun dönem prognozu hala tart›ş›lmaktad›r.Anahtar Sözcükler: Avulsiyon, gecikmiş replantasyon, dental travma GİRİŞ 7-10 yaşlar›ndaki çocuklarda daimi anterior dişlerdeki travmatik yaralanmalar›n yaklaş›k % 0.5-16's› diş avülsiyonu ile sonuçlanmak-tad›r (1).
