Influence of the power level of an ultra-sonic system on dental cavity preparation
(2007-12-31)
The aim of this study was to evaluate the shape of dental cavities made with the CVDentus® system using different ultrasound power levels. One standard cavity was made on the buccal aspect of 15 bovine incisors with a ...
Cutting characteristics of dental diamond burs made with CVD technology
(2006-04-01)
The aim of this study was to determine the cutting ability of chemical vapor deposition (CVD) diamond burs coupled to an ultrasonic dental unit handpiece for minimally invasive cavity preparation. One standard cavity was ...
Restorative treatment on class I and II restorations in primary molars: A survey of Brazilian dental schools
(2005-12-01)
A survey was sent to 70 Brazilian dental schools evaluating techniques and restorative materials being taught for Class I and II preparation in posterior primary teeth by Pediatric Dentistry courses. After a 54% response ...
Reactionary dentinogenesis after applying restorative materials and bioactive dentin matrix molecules as liners in deep cavities prepared in nonhuman primate teeth
(Blackwell Publishing, 2006-06-01)
Objective: the aim of this in vivo study was to evaluate the response of the pulp-dentin complex following application of resin-modified glass-ionomer cement, calcium hydroxide hard-setting cement and EDTA-soluble preparation ...
Influence of cavity preparation and curing method on the marginal seal of resin composite restorations: an in vitro evaluation.
(2007-03-01)
OBJECTIVE: To evaluate the influence of cavity design and photocuring method on the marginal seal of resin composite restorations. METHOD AND MATERIALS: Seventy-two bovine teeth were divided into 2 groups: group 1 received ...
Clinical evaluation of proximal contacts of Class II esthetic direct restorations
(2004-11-01)
Objective: This study evaluated the effectiveness of proximal contacts in Class II restorations using two types of matrix bands (steel and polyester) with two different restoration techniques (incremental and with ...
Evaluation of the dentin-pulp complex after cavity preparation with ultrasonic diamond tip
(2011-01-01)
The aim of this paper was to compare the dentin-pulp complex response to cavity preparation in human teeth using ultrasonic chemical vapor deposition (CVD) diamond tip and high-speed diamond bur. Class V buccal cavities ...
Evaluation of cutting patterns produced with air-abrasion systems using different tip designs.
(2001-05-01)
This study assessed cavity preparations produced with different air abrasion tip parameters. Twelve test groups of extracted teeth were prepared to evaluate the parameters of 80 degrees or 45 degrees nozzle angles and 0.38 ...
Treatment options for the occlusal surface of first permanent molars
(2004-09-01)
Restorative dentistry has been increasingly concerned with preservation of the dental structure. For that reason, ultraconservative cavity preparations have been performed with air abrasion systems. The aim of this study ...
Using the self-etch adhesives in anterior restoration
(2012-05-01)
With the arrival of self-etch adhesives systems, there has been a rise in interest among clinicians, making it imperative for health professionals to have knowledge of the properties, characteristics, the association as ...
