[Abstract in English is at the end of the manuscript] GİRİŞKök kanal tedavisinde kök kanallarının biyomekanik preparasyonunun başarı ile tamamlanmasından sonra kök kanal sisteminin yeniden enfekte olmasını engellemek amacıyla kök kanal dolgusu yapılmalıdır. Bu amaç ile birçok kök kanal dolgu maddesi piyasaya sürülmüş-tür. Uzun yıllar boyunca, kök kanalı dolgu materyali olarak kullanılan güta-perka, biyouyumluluğu ve kolay uygulanabilir olması nedeni ile günümüzde de güncelli-ğini korumaktadır.1 Ancak, basınca karşı dayanıksızlık göstermesi, sertliğinin yeterli olmaması ve en önemlisi adeziv özellik göstermemesi nedeniyle kök kanal tedavisinde alternatif kök kanal dolgu maddeleri araştırılma-ya devam etmektedir.2 GuttaFlow (Coltène/Whaledent, Langenau, Almanya) güta-perka tozları ve polidimetilsiklosan içeren silikon-esaslı bir kök kanal dolgu materyalidir. Sertleşirken hafifçe genişlemesi ve akışkanlığı, kök kanal duvarları-na ve güta-perkaya iyi adaptasyon göstermesini sağla-maktadır. 3Kök kanal tedavisinin başarısız olduğu durumlarda öncelikli tedavi seçeneği kök kanal tedavisinin yenilenmesidir. Kök kanal tedavisinin yenilemesinin ilk defa yapılan kök kanal tedavisine kıyasla daha uzun zaman aldığı bildirilmiştir. 4 Kök kanalı dolgusunun kök kanallarından mekanik uzaklaştırılmasını kolaylaştırmak amacıyla birçok çözücü madde kök kanal tedavisi yenileme tedavisinde kullanılabilmektedir. 4 Kloroform ucuz, güta-perka çözebilme etkinliği fazla olan ve hızla etki gösteren bir çözücüdür. Fakat potansiyel olarak karsinojen etkisinin bulunması ve canlılar üzerinde toksik etkiye sahip olması nedeniyle kullanımı sınırlandırılmış bir maddedir.5 Portakal yağı doğal bir

“…In particular co-registration is essential to obtain quantitative evaluation of endodontic treatment. Following the development of previous software and methods targeted to endodontic investigation [1,2] , we were able to increase reliability and flexibility of the analysis. Of course our analytical procedures are not general but suited for the endodontic case.…”

“…Thanks to its intrinsic non-destructive character, µCT can be used to provide evidence of tissue surface and volume changes over time. As an example, it is possible to scan a sample before and after a specific treatment, in order to evaluate possible modifications of its 3D structure [1,2,9] . Furthermore, internal and external anatomy can be provided simultaneously or separately [10] .…”

Background: The 3D images of dental specimens were obtained by means of micro-Computed Tomography (µCT) before and after therapeutic intervention. A suite of software tools has been developed to assess the efficacy of dental treatment as revealed by µCT scans. Endodontic root canal and restorative therapy were selected as model procedures to test and optimize the developed tools. Non destructive µCT imaging allows repeated scans of the same tooth and might provide quantitative information about specimen modifications over time. Preliminary literature has suggested that anatomical characterization and detailed evaluation of dental therapies would considerably benefit from the coupling between detailed 3D imaging and custom software. However, the main drawbacks reside in time consuming pipeline for scanner-time of the specimens and absence of efficient software for accurate data analysis and direct comparison of a set of 3D dental structures. Methods:The software we present here implements co-registration procedures together with an algorithm for the 3D quantitative characterization of teeth hollow spaces and interfaces. The software is targeted to the individualized analysis of the single specimen in an effort to help dentists to quantify the outcome of the surgical intervention performed on teeth. The approach aims to automatically highlight the differences between pre-and post-treatment structures for further anatomical and statistical analysis. Of note, the two different treatments analyzed exploit two different perspectives. As a matter of facts, endodontic therapy aims at the modification of the root canal structure (axe, volume and surface), whereas the restorative treatment focus is on the whole tooth structure. Results:The developed co-registration algorithm allows finding correct superposition in both data sets, despite the preand post-structure can be markedly different, especially after the application of dental adhesive composite in the restorative treatment. Tools for characterization of canal volume and surface are robust with respect to the presence of branches and allow the complete characterization of the endodontic treatments. Modification of the tooth structure after restorative treatments is highlighted after the co-registration procedure in automatic way and allows the user to quantify the volume of voids due to the shrinkage of the material at the interface and eventually the presence of internal cracks or other morphological modification of the tooth structure.www.sciedu.ca/jbgc Journal of Biomedical Graphics and Computing, 2013, Vol. 3, No. 4 ISSN 1925-4008 E-ISSN 1925 86 Conclusions: We demonstrate the effectiveness of customization of 3D data analysis tools to obtain specific characterization and quantitative information about different dental therapies.

Micro‐CT evaluation of residual material in canals filled with Activ GP or GuttaFlow following removal with NiTi instruments

Abstract: Both root fillings with ActivGP and GuttaFlow were removed with nickel-titanium rotary instruments. Enlargement of canals up to two sizes beyond the pre-retreatment size was necessary to minimize the amount of sealer remaining.
