Dental emergencies in a university pediatric dentistry clinic: a retrospective study Abstract: A significant number of children visit a dentist for the first time due to emergency situations. However, little is known regarding the prevalence, etiology, and treatment provided for children at emergency dental visits. This study aimed to evaluate the profile of children attending a dental school emergency clinic, the reasons for seeking dental care, and the treatment provided. Records of 270 patients who attended an emergency clinic during 2010 were analyzed, and 253 were selected. Demographic, diagnostic, and procedural information was collected. The mean child age was 7.8 years. For 208 children (82%), pain was the main reason for the emergency visit. Nearly 79% of the visits were due to caries, and the most frequently required treatment was endodontic intervention (31.22%). Of the decayed teeth, 61.70% were primary posterior teeth and 31.9% permanent posterior teeth. Pain caused by dental decay was the most frequent chief complaint. A large number of children were brought to the dentist with complaints that had started long before, for which over-the-counter medications had been used.

Exposure to a staining agent, cumulative exposure time, and commercial brand are factors that influence the color stability of clear elastic ligatures.

As the silane impaired or generally had no effect on the bond strength of SARCs to the glass fibre posts, and also as the bond strength of all SARCs was higher than the conventional cement when the posts were not silanated, it seems that silanization of glass fibre posts is not necessary when SARCs are used.

The use of translucent post may positively influence the polymerization efficiency and bond strength of resin cement to intraradicular dentin.

The use of a whitening dentifrice containing blue pigment during orthodontic treatment might decrease the yellow discoloration of elastic ligatures.
