Nano/micro fluorhydroxyapatite crystal pastes in the treatment of dentin hypersensitivity: an in vitro study.

Objectives: Dentin hypersensitivity (DH) is a prevalent problem. This study aimed to formulate a paste using fluorhydroxyapatite (FA) crystals dispersed in different carriers to treat DH. The ability to occlude patent dentinal tubules and to release ions was investigated.

Hypocone reduction and Carabelli's traits in contemporary Jordanians and the association between Carabelli's trait and the dimensions of the maxillary first permanent molar.

The objective of this study is to determine the prevalence of expression and bilateralism of two dental morphological traits in contemporary Jordanians: The hypocone reduction trait on the maxillary second permanent molar and Carabelli's trait on maxillary permanent first and second molars. Furthermore, inter-trait correlation and the relationship of Carabelli's traits with upper first molar dimensions were investigated. Three hundred subjects of school children at their 10th grade and of an average age of 15.

The effects of disinfectants on dimensional accuracy and surface quality of impression materials and gypsum casts.

Background: The study aimed to evaluating the effect of disinfecting impression materials on the dimensional accuracy and surface quality of the resulting casts.

Methods: Impressions of a steel die constructed according to ANSI/ADA specification No.18 were made with each of alginate, addition cured silicone, condensation cured silicone and zinc oxide eugenol paste, and disinfected consequently by each of 0.

The relationships of the maxillary central incisors and canines to the incisive papilla in Jordanians.

Aim: The validity of the relationship between the maxillary anterior teeth and the incisive papilla and the pertinence of this relationship to Jordanians was examined.

Methods And Materials: A computerized digital caliper (CDC) tool was developed and used in the measurements which were made on scanned images of dental casts of 298 Jordanians. The distances from a tangent to the labial surface of the central incisors to the midpoint and the posterior border of the incisive papilla were measured.

Prevalence, association, and sexual dimorphism of Carabelli's molar and shovel incisor traits amongst Jordanian population.

Introduction: The correlation between dental morphological traits can be used as an indicator to show major ethnic differences. Therefore, this study investigated the prevalence of Carabelli's molar and shovel incisor traits and tested their association and sexual dimorphism in Jordanian population.

Material And Methods: Three hundred subjects of school children at their 10th grade and of 15.
