Abstract

Statement of the Problem: Pit and fissure sealant placement is considered as an effective modality for prevention of caries on occlusal surfaces. Penetration, retention and lateral wall adaptation are the key factors in success of pit and fissure sealant restorations.
Purpose: The purpose of this paper was to compare penetration ability and lateral wall adaptation of three commercially available pit and fissure sealants.
Materials and Method: The present in-vitro study was done on 45 extracted sound human molars to evaluate the fissure pattern and assess the penetration ability of three commercially available sealants [Delton® FS Sealant (Dentsply DeTrey GmbH, Konstanz, Germany), Clinpro Sealant (3M ESPE, Minnesota, USA) and GC Fuji VII Glass Ionomer Cement (GC Asia Dental Pte Ltd, Singapore)] on molars divided into 3 equal groups of 15 each, with further sectioning of each sample into 2 parts giving 30 samples per group. Following thermocycling and embedding of teeth in clear auto-polymerizing acrylic resin, sections were evaluated for fissure morphology, sealant penetration, unfilled space, lateral wall adaptation, and for presence of voids.
Results: Penetrability of all the sealants studied was found to be significantly more in U-type fissure pattern (93.89%) followed by V-type (78.62%), IK-type (74.34%) and then in I-type (65.91). The depth of penetration of the GC Fuji VII Glass Ionomer sealant (85.82%) was found to be superior followed by unfilled resin sealant (Clinpro Sealant- 78.26%) and then by filled resin sealant (Delton® FS Sealant- 74.89%).
Conclusion: U- type fissure pattern was more common than other fissure patterns and showed significantly higher penetrability of different type of sealants evaluated in the present study. GIC based sealant, due to significantly higher penetration depth than unfilled and filled sealants used in the present study, can be preferred over filled or unfilled resin sealants.

Dentsply Sirona Lab Introduces SW 18…

More indications, more functions – inLab SW 18.0 enhances CAD/CAM workflow in dental technology

Dentsply Sirona Lab, the newly created business unit, has launched inLab SW 18.0 as of April 2018. This new software has optimized the functional scope and handling of the CAD and CAM software for an even wider range of applications and more efficient production procedures in the dental laboratory. All inLab software application modules benefit from the innovations.
Bensheim/Salzburg, 16 May 2018. The success of a CAD/CAM workflow in the dental laboratory is essentially a software question. The software should cover a wide spectrum of indications and functions and simultaneously work in a user-friendly way. These are the characteristics that will prove the value of the latest inLab SW 18.0 update across the board.
New uses – More design options
The previous model design has been improved, so that now full-arch models with removable dies and models with implant analogs can be constructed, including a separate gingival mask for any kind of model. Different articulator systems can be put in and the model can be marked individually. The completed model data for production can be provided with a 3D-printer or in central production via the optional STL interface. 
In the area of implant restorative solutions, inLab is the first program to offer the option to design multilayer gingival bridges for the production of highly esthetic, directly attached implants with a gingival section. The structure with the gingival section can be separated from the veneer structure for production from different materials, and the veneer structure can be processed as one piece, split into individual crowns, or made from a combination of the two depending on the esthetic goal.
A special feature of the current inLab SW is the new “1:1 Copy Mode”. Using this additional copy function, all geometries of a restoration can be copied exactly in accordance with the original and transferred – ideally for large bridges and implants with a gingival section, when, for instance, any adjustments to long-term temporary solutions are transferred into the final restoration. This saves dental technicians an enormous amount of time and they can take over any attachment geometries 1:1.
 “We have significantly expanded and upgraded the inLab SW 18.0 especially where it can efficiently support the dental laboratory and where it guarantees more ease of use,” summarizes Jörg Haselbauer, Product Manager for CAD/CAM Laboratory Software at Dentsply Sirona. “This pertains to gingival elements for bridges and for choosing original attachment geometries for slide attachments. Additionally, the revised administration phase now offers the user – in a clearly organized overview on a screen – an intelligent tool for quickly and accurately positioning and managing restorations and flexible adjustment options during the design phase.” 
Lab-to-lab workflow with Dentsply Sirona
For the first time, an inLab laboratory can transfer scan or restoration data quickly and safely to another inLab laboratory and receive it back again via the Sirona Connect Portal to make optimal use of construction and production capacities, for example. This new function also simplifies access to the patient-specific solutions from Atlantis directly from the inLab SW – for the design and manufacture of implant abutments and suprastructures by Dentsply Sirona. 
Inclusive inLab CAM software update 
The inLab SW 18.0 update includes the inLab CAD SW 18 and the inLab CAM SW 18.0. The new CAM software supports the inLab MC X5 and inLab MC XL production units with optimized workflows. The new archiving function, the option to reuse material, a simplified pin tool, and other improvements in the details boost efficiency and safety when using machines on a daily basis. The new tool status display reliably informs the user about the status of the tool’s wear and tear when using validated materials. Additional materials from Dentsply Sirona and others are also integrated and validated in inLab CAM, such as Cercon ht, Cercon xt, Lucitone 199, Wax Disc, Multilayer PMMA, Shaded PMMA, Burnout PMMA Disc and Celtra Duo. 
Digital Denture Milling
The Lab SBU is pleased to announce that the inLab MC X5 milling machine has been cleared for launch—supporting the milling of digital dentures. The inLab MC X5 has been a dependable solution for producing bonded dentures using the Lucitone 199 digital denture disc, Portrait IPN denture teeth, and HIPA as a bonding system. This unit is part of the Dentsply Sirona Digital Denture system (equipment and materials) and has been qualified to be compatible with denture workflows using the engineered by AvaDent design engine.
The inLab SW 18.0 update is available to currently inLab commercial dental lab customers by registering on the Software Downloads page at www.dentsplysirona.com/inlab.

Dentsply Sirona Unveils SICAT Endo 3D Software at CDA Meeting in Anaheim…

Faster, safer, and more efficient endodontic treatment with SICAT Endo

Dentsply Sirona is introducing another integrated solution to the dental market ‒ the new SICAT Endo 3D software for improved planning and workflow in endodontic treatment. SICAT Endo also enables you to order special surgical guides for guided endodontic treatment. Advantages of the software: enhanced diagnostics, improved certainty in planning, and optimized accuracy of treatment through the use of surgical guides.
Charlotte, NC (May 17, 2018) – SICAT Endo is the first and only fully integrated and complete 3D solution for the diagnosis and planning of endodontic treatment that also supports clinical implementation with surgical guides. Using the software, all root canals can be easily identified in 3D, and the working length and depth of the access cavity can be determined precisely. Even heavily curved and calcified canals can be diagnosed easily. This process considerably improves the endodontic workflow for practitioners. The user-friendly software has diagnostic advantages for optimal treatment planning ‒ efficient, reliable, with predictable outcomes.
Introducing fusion of 2D images with 3D Data
The combination of high-resolution intraoral 2D X-ray images and the depth information from 3D X-ray data facilitates diagnostics considerably. Thanks to the simultaneous navigation in 2D and 3D, dentists are easily oriented in all dimensions and can concentrate on the root canal to be diagnosed.
SICAT Endo is optimized for 2D and 3D X-ray units and CEREC by Dentsply Sirona. The software is fully integrated in Sidexis 4 with 3D data from Galileos and Orthophos SL units combined with 2D data; including Schick 33 and Schick Elite sensors. No export and manual import of data are required. The integration of optical impressions allows the occlusal surface to be visualized precisely, thus optimizing planning for the access cavity and the exact determination of the working lengths.
Jochen Kusch, Managing Director of SICAT GmbH & Co. KG: “With the SICAT Endo software, we have taken a major step towards the diagnostics, planning, and implementation of endodontic treatment. We developed surgical guides for the opening of the root canal, and this is innovative in the dental market. The specific endodontic tools in the software such as 360° visualization of the root canals, the integration of 2D and 3D views, and the integration of optical impressions for the precise visualization of the occlusal relief are crucial support for practitioners in diagnostics and treatment planning.”
Guided root canal treatment with surgical guides
After identifying and diagnosing all root canals in SICAT Endo, dentists can order a SICAT ACCESSGUIDE surgical guide. The use of the surgical guide for opening the root canal helps make endodontic treatment even more effective, safer, and more precise. The surgical guide enables minimally invasive and efficient preparation of cavity access. SICAT ACCESSGUIDE guides are available for orthograde root canal treatment.
