The Effect of Primary Root Canal Treatment on Dentinal Tubule Penetration of Calcium Silicate-based Sealers during Endodontic Retreatment.

Introduction: The aim of this study was to evaluate the effect of previous root canal treatment on dentinal tubule penetration of calcium silicate-based sealers during endodontic retreatment and to compare 2 different (commonly used and modified) tubule penetration depth measurement techniques.

Methods: The crowns of mandibular premolar teeth were removed, and root canals were prepared (ProTaper Universal; Dentsply Sirona, York, PA) and obturated using AH Plus (AH; Dentsply DeTrey, Konstanz, Germany), MTA Fillapex (MTAF; Angelus, Londrina, Brazil), and WellRoot ST (WRST; Vericom, Gyeonggi-do, South Korea); 0.1% red Rhod-2 dye (Chemodex, St Gallen, Switzerland) was added to the sealers.

An evaluation of quality of life of mothers of children with enuresis nocturna.

The aim of this study was to evaluate the impact of enuresis nocturna on quality of life of the mothers. Mothers who have a child with monosymptomatic nocturnal enuresis (n=28) and mothers who have a child without any health problems (n=38) were enrolled in the study. Groups were in balance for background variables (child's age, gender, and number of siblings; mother's age, marital status, highest year of education completed, and occupation; presence of health insurance; and type of residence).

Evaluation of voiding dysfunctions in children with chronic functional constipation.

There are controversial results about the role of dysfunctional bowel emptying in disorders of the urinary tract like urinary tract infection (UTI), vesicoureteral reflux (VUR) and enuresis. Constipation may cause UTI, enuresis and VUR due to the uninhibited bladder contraction. The aim of this study was to investigate the frequency of nocturnal enuresis, UTI and instability symptoms in chronic functional constipation (CFC).

Frequency and characteristics of mongolian spots among Turkish children in Aegean region.

Mongolian spots, which are benign congenital lesions observed in the first years of life, can cause distress for parents due to aberrant localization as well as unexpected number and size. Therefore, efficient differential diagnosis is necessary. The aim of this study was to determine the frequency and characteristics of mongolian spots in 1-12-month-old children in a west Anatolian city and to evaluate parental approach to these lesions.
