Color Match Between Composite Resin and Tooth Remnant in Class IV Restorations: A Case Series.
Operative Dentistry
|March 17, 2018
Summary
Achieving optimal shade matching for composite resin restorations, particularly Class IV, requires considering tooth rehydration and resin polymerization. A 14-day clinical assessment period is recommended for reliable color match evaluation in dental restorations.
Area of Science:
- Dentistry
- Dental Materials Science
- Restorative Dentistry
Background:
- Accurate shade selection of composite resin is crucial for aesthetic dental restorations.
- Factors like tooth rehydration and composite resin polymerization significantly influence final color match.
- Class IV restorations, involving incisal edges, present unique challenges for achieving seamless shade integration.
Purpose of the Study:
- To evaluate the color match between composite resin (CR) and tooth remnant (TR) in Class IV restorations over time.
- To determine the optimal time frame for assessing the color stability and match of composite resin restorations.
- To analyze changes in translucency, luminosity, and saturation of composite resin restorations post-procedure.
Main Methods:
- A case series involving thirteen Class IV restorations in maxillary central incisors.
- Color match assessment using spectrophotometry to measure ΔE values between TR and CR at multiple time points (baseline, 48 hours, 7, 14, and 28 days).
- Qualitative analysis of translucency, luminosity, and saturation via digital photography.
Main Results:
- The color difference (ΔE) between composite resin and tooth remnant was statistically similar at 14 and 28 days (p>0.05).
- Most restorations maintained stable saturation and luminosity.
- A notable change in translucency was observed over the evaluation period.
Conclusions:
- A 14-day clinical assessment period is sufficient to establish a reliable color match for composite resin in Class IV restorations.
- Understanding the dynamic changes in tooth and resin properties is essential for long-term aesthetic success.
- The study highlights the importance of considering rehydration and polymerization effects on shade selection for dental composites.

01:20Antiarrhythmic Drugs: Class IV Agents as Calcium Channel Blockers
2.2K
Class IV antiarrhythmic drugs, such as verapamil and diltiazem, block calcium channels. They primarily affect the heart, slowing the conduction in calcium-dependent tissues like the SA and AV nodes. These drugs manage reentrant supraventricular tachycardia (SVT) and reduce ventricular rate in atrial flutter/fibrillation.
Verapamil, a calcium channel blocker, inhibits calcium movement across myocardial cell membranes and vascular smooth muscle. This results in the dilation of coronary and...

2.4K
Restorative care is provided once a patient has been discharged from a healthcare facility and requires additional services. The additional services include home care, rehabilitation programs, and extended care. Restorative care centers help the patient regain their previous level of functioning or acquire a new level of functioning due to the incapacitating effects of a disease or a disability. It aims to assist patients in enhancing their quality of life by encouraging independence,...

Color in Coordination Complexes
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human...

427
The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values.

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...

1.5K
Color perception begins in the retina, the light-sensitive layer at the back of the eye. Two main theories explain how colors are seen: the trichromatic theory and the opponent-process theory. The trichromatic theory, proposed by Thomas Young in 1802 and extended by Hermann von Helmholtz in 1852, suggests that color vision is based on three types of cone receptors in the retina. These cones are sensitive to different but overlapping ranges of wavelengths corresponding to red, blue, and green.
