[Collection of epidemiological data on oral and dental health in young children. Pilot study conducted with 212 children in 11 ONE centers in the Province of Liège].

Dental caries still affect 60 to 90 % of children attending school worldwide. We collected epidemiological data from 212 children under the age of 6 supervised by the Office of Birth and Childhood in the Province of Liège. We analyzed the relationships between the prevalence of dental caries in the studied population sample and the risk factors that are usually associated to dental carries.

[The importance of pulp therapy in deciduous teeth].

Preserving primary teeth is crucial for maintaining the maxillary growth, aesthetics, mastication, and speech and for preventing from abnormal habits. Given the peculiar anatomy of the primary tooth, caries grow faster and more frequently to the pulp. In pediatric dentistry, new methods and enhanced material have been recently released on the market and broadened the field of treatments.

Microleakage after Thermocycling of Three Self-Etch Adhesives under Resin-Modified Glass-Ionomer Cement Restorations.

This study was designed to evaluate microleakage that appeared on Resin-Modified Glass-Ionomer Cement (RMGIC) restorations. Sixty class V cavities (h x w x l = 2 mm x 2 mm x 3 mm) were cut on thirty extracted third molars, which were randomly allocated to three experimental groups. All the buccal cavities were pretreated with polyacrylic acid, whereas the lingual cavities were treated with three one-step Self-Etch adhesives, respectively, Xeno III (Dentsply Detrey GmbH, Konstanz, Germany), iBond exp (Heraeus Kulzer gmbH & Co.

[Caries prevalence among children in Belgium].

The limited epidemiological data on dental health in Belgium has led our team to conduct a pilot study in this field. Children, aged from 6 to 12 years old came from two primary schools located in the area of Liège, and were clinically examined for their dental health. The main recorded dental parameters were the number of decayed, missed or filled teeth (epidemiological score DMFT) as well as the amount of dental plaque on the buccal side of the teeth.

[Bonding-cementation of all-ceramic restorations].

The objective of this article is to synthesize the current scientific data relating to the bonding of ceramic restorations in order to present a reliable and reproductive clinical method for the general practitioner. The different ceramic treatments are explained with a distinction between those which can be etched and the others. A precise check list is suggested for the conditioning of dental tissues and ceramic surfaces.

Microleakage after thermocycling of 4 etch and rinse and 3 self-etch adhesives with and without a flowable composite lining.

This study evaluated the microleakage of composite fillings prepared with 4 etch and rinse and 3 self-etch adhesive systems after thermocycling. Also evaluated was the potential improvement of cavity sealing when utilizing a low charged resin lining for cavity preparations. Seventy recently extracted teeth were randomly allocated to 7 experimental adhesive systems: two 3-step etch and rinse adhesive systems, Scotchbond Multipurpose (SBMP) and Optibond Solo Plus (OS); two 2-step etch and rinse adhesive systems, referred to as "one-bottle," Scotchbond 1 (SB1) and Gluma Comfort Bond + Desensitizer (G); and 3 self-etch "all-in-one" adhesives, Adper Prompt-L-Pop (PLP), Xeno III (X-III) and iBond (iB).

Experimental comparison of cavity sealing ability of five dental adhesive systems after thermocycling.

Purpose: To evaluate the cavity sealing obtained after thermocycling with five adhesive systems in which one all-in-one adhesive was compared to three one-bottle adhesives, and to observe the effect of a low-charged resin layer added to a one-bottle adhesive.

Materials And Methods: Twenty-five recently extracted teeth were randomly allocated to five experimental adhesive systems (n = 5 each): Optibond Solo (OS), Scotchbond 1 (SB1), PQ 1, Prompt-L-Pop (PLP), SB1+Revolution (R). On each tooth, two rectangular cavities at the cementoenamel junction were filled with a microhybrid composite (Z100) and the tested adhesives.
