Medial and lateral canthal distances in unrepaired cleft lip and palate Nigerians
Medial canthal distance (MCD) (inner canthal distance) refers to the distance between the two medial canthal of the eyes, while lateral canthal distance (LCD) (outer canthal distance) is the distance between the two laterals canthal of the eye. Accurate measurements of these distances are necessary for the diagnosis of true ocular hypertelorism and a guide in both reconstructive surgery and orthodontic treatment. The...

Using electric current during dentin bonding agent application and its effect on microleakage under simulated pulpal pressure conditions
The use of electric current during application of etch-and-rinse adhesive systems has been recently introduced to decrease microleakage. This study investigated the effects of an electric field produced by an experimental device for the application of a two-step etch-and-rinse adhesive on moist dentin surface. Sixty freshly extracted human premolars were used for this study. In order to simulate real conditions, the...
