Despite of the decline of dental caries, this disease is still common in polarized groups affecting children. Therefore, the aim of this randomized blind in vivo study was to compare the antimicrobial effect of two antimicrobial therapies in deciduous carious dentin. Thirty two patients aging from 5 to 7 years old had partial caries removal in deep carious dentin lesion in deciduous molar and were divided in three groups: Control - chlorhexidine and resin modified glass ionomer cement (RMGIC); LEDTB - antimicrobial photodynamic therapy (APDT) with LED associated with toluidine blue orto dye solution and RMGIC; LMB - APDT with laser associated with methylene blue dye solution and RMGIC. The patients were submitted to initial clinical and radiographic examination and demographic features were evaluated by biofilm, gingival, and dmft/dmfs indexes, besides clinical and radiographic follow up at 6 and 12 months after the treatments. The carious dentin was collected before and after each treatment and the number of Streptococcus mutans, Streptococcus sobrinus, Lactobacillus casei, Fusobacterium nucleatum, Atopobium rimae and total bacteria were established by quantitative PCR.

This case report aims to demonstrate the regenerative potential of particles obtained from a crushed extracted tooth. Following tooth removal, the clean root was ground and the dentin and cementum gra...
In recent years, the risk of allergy to chlorhexidine is increasingly recognised. In this review, we discuss why the allergy is so easily overlooked and point out several preventative initiatives that...
Since 2011, 2% chlorhexidine in 70% isopropyl alcohol (2% chlorhexidine tincture) has been widely used in Korea. To investigate changes in chlorhexidine sensitivity of staphylococci causing central li...

Extracellular matrix (ECM)-based biomaterials developed from mammalian tissues have been successfully used in preclinical and clinical tissue engineering applications. We have previously reported abou...
Adherent debris produced when cutting the enamel or dentin in cavity preparation. It is about 1 micron thick and its composition reflects the underlying dentin, although different quantities and qualities of smear layer can be produced by the various instrumentation techniques. Its function is presumed to be protective, as it lowers dentin permeability. However, it masks the underlying dentin and interferes with attempts to bond dental material to the dentin.
An autosomal dominant disorder of tooth development characterized by opalescent dentin resulting in discoloration of the teeth, ranging from dusky blue to brownish. The dentin is poorly formed with an abnormally low mineral content; the pulp canal is obliterated, but the enamel is normal. The teeth usually wear down rapidly, leaving short, brown stumps. (Dorland, 27th ed)
The process of TOOTH formation. It is divided into several stages including: the dental lamina stage, the bud stage, the cap stage, and the bell stage. Odontogenesis includes the production of tooth enamel (AMELOGENESIS), dentin (DENTINOGENESIS), and dental cementum (CEMENTOGENESIS).
Sheets of latex rubber punched and placed over the teeth during dental procedures to isolate the field of operation from the rest of the oral cavity (Jablonski; Illustrated Dictionary of Dentistry, 1982). Rubber dams are useful in preventing the swallowing of instruments or restorations during dental work.
An apparently hereditary disorder of dentin formation, marked by a normal appearance of coronal dentin associated with pulpal obliteration, faulty root formation, and a tendency for peripheral lesions without obvious cause. (From Dorland, 27th ed)
