Summary
This study presents two methods for reconstructing the cemento-enamel junction (CEJ) before root coverage therapy (RCT) for non-carious cervical lesions (NCCLs). Both analog and digital techniques successfully restored tissue and improved gingival recession outcomes.
Area of Science:
- Dental Restorations
- Periodontology
- Prosthodontics
Background:
- Non-carious cervical lesions (NCCLs) involve dental hard tissue loss at the cemento-enamel junction (CEJ).
- NCCLs complicate the diagnosis and treatment of gingival recessions (GR).
- Established protocols for CEJ reconstruction prior to root coverage therapy (RCT) are lacking.
Observation:
- Two patients with GR and NCCLs underwent CEJ reconstruction using analogically and digitally guided techniques.
- Therapeutic CEJ position was predetermined, followed by analog or digital diagnostic wax-up.
- Restorations utilized direct composite resin, with RCT performed one week later.
Findings:
- Both analog and digital CEJ reconstruction techniques resulted in complete root coverage and effective soft tissue healing at 6 months.
- The analog technique's outcomes are operator-dependent, while digital methods are effective but costly.
- CEJ reconstruction enhances multidisciplinary team communication and ensures precise gingival margin placement.
Implications:
- CEJ reconstruction prior to RCT may improve treatment prognosis for non-carious cervical lesions.
- Diagnostic wax-ups are crucial for creating accurate prosthetic guides for CEJ reconstruction.
- These techniques facilitate optimal aesthetic results and precise gingival margin positioning in complex restorative cases.

01:28Water Cement Ratio
The water-cement ratio is pivotal in defining concrete's quality. This ratio, a balance between the weight of water and cement in the mix, shapes the concrete's strength, durability, and resistance to environmental factors. As identified by Abrams’ law, less water in the mix equates to stronger concrete. However, water is essential not only for the chemical process of hydration but also for the concrete's workability and compaction. While hydration chemically binds water and cement, physical...
01:16Dynamic Modulus of Elasticity of Concrete
The dynamic modulus of elasticity assesses how a concrete structure deforms under impact or dynamic loads. It is typically higher than the static modulus of elasticity, measured under slow, steady loading conditions.
The sonic test is a common method to determine the dynamic modulus. In this test, a concrete beam, sized either 6 x 6 x 30 inches or 4 x 4 x 20 inches, is clamped at its center. Vibrations are initiated at one end of the beam by an electromagnetic exciter unit powered by a...

01:25Permeability of Concrete
Permeability in the context of concrete refers to how easily liquids or gases can pass through the material. This quality is crucial for assessing the water-tightness and durability of concrete structures and their resistance to chemical attacks. Concrete permeability can be determined through comparative laboratory tests. These tests typically involve sealing a concrete specimen from the sides, applying water pressure to the top surface with pressure, and measuring the amount of water passing...
01:22Effect of Sea Water on Concrete
Concrete exposed to seawater can undergo degradation like the dissolution of ettringite and gypsum, increasing the material's porosity and decreasing its strength. In contrast, the crystallization of salts within the concrete's pores can cause expansion, particularly above the waterline where evaporation occurs. Nonetheless, this expansion only happens when seawater, enabled by the concrete's permeability, manages to infiltrate the structure.

01:12Modeling and Similitude
Scaled modeling is a fundamental technique in engineering, enabling the study of large and complex systems by creating smaller, manageable replicas that recreate critical characteristics of the original. In hydrology and civil infrastructure, for example, scaled models of dams help analyze water flow, turbulence, and pressure. This method allows for accurate predictions of real-world behavior within a controlled environment, significantly reducing the cost and time involved in full-scale...
01:30Typical Model Studies
Fluid mechanics model studies often utilize scaled-down systems to predict fluid behavior in full-scale environments, such as river flows, dam spillways, and structures interacting with open surfaces. Maintaining Froude number similarity in river models is crucial, as it replicates surface flow features like wave patterns and velocities.
