AI Article Synopsis
- The study examined how well plastic and metal Thermafil obturators seal the ends of root canals in extracted human teeth.
- Radiographic analysis revealed no significant differences in filling accuracy or microleakage between the two materials.
- Smaller sized obturators, regardless of material, tended to have more voids, but overall, both types performed similarly in preventing leakage.
Article Abstract
This study compared the apical seal of plastic versus metal Thermafil obturators in extracted human teeth. The obturated teeth were evaluated radiographically for the extent and adaptation of the filling obturator. No difference was seen between plastic and metal for over- or underfilling. Voids were seen more often in smaller sizes of both plastic and metal obturators. Obturated teeth were stained in India ink, decalcified, and cleared. Microleakage evaluation of the transparent teeth showed no statistical difference between metal and plastic obturators.

Aim: This study aimed to investigate and compare the total and sectional bond strengths of three endodontic sealers when used with the single-cone obturation technique.
Materials And Methods: Forty-five human maxillary central incisors were prepared and divided into three groups according to the type of endodontic sealer: Group I (Gutta-percha/AH Plus Jet), group II (Gutta-percha/GuttaFlow 2), and group III (RealSeal/RealSeal SE). All canals were filled with the single-cone technique.

Objectives: This study evaluates the effect of different irrigation solutions for postoperative pain in the regenerative endodontic treatments (RET) of necrotic teeth with open apex.
Materials And Methods: This study included necrotic, deeply carious lower molars of 42 patients. Access cavities of the teeth were opened and working lengths were measured at the first visit.

Introduction Endodontic re-infections primarily occur due to the ingress of bacteria and their toxins through an incomplete seal following obturation. A variety of sealers have been developed to achieve effective integration with the different obturation materials and dentinal tubules. To choose the right endodontic sealer and application for each clinical instance, one must be aware of the attributes of the various sealers commonly used in clinical practice.

Purpose: This study was aimed to compare the difference between iRoot SP and AH Plus on root canal sealing ability for teeth extracted due to severe periodontitis and explore whether the dentin tubule pathway plays an important role in the development of endodontic-periodontic lesions(EPL), in order to provide a theoretical basis for selection of proper time for root canal therapy and suitable root canal sealants in patients with EPL.
Methods: Fifty single-root anterior teeth extracted due to severe periodontitis were selected. The roots were completely debrided to remove the calculus, dental plaque and cementum.

Statement Of The Problem: The creation of a proper seal of the root canal with canal-filling materials, such as gutta-percha and sealer, is one of the essential factors in the success of root canal treatment. In addition, the penetration depth of the sealer is one of the influential factors in creating a proper seal, which improves the sealing ability of the canal and the burial of microorganisms.
Purpose: This study aimed to investigate the effect of cold atmospheric plasma on the depth of tubular penetration of two types of resin sealer: AH26 and Beta RCS sealers.
