Picture Examination Communication System Versus Video Modelling in Improving Oral Hygiene of Children with Autism Spectrum Disorder: A Prospective Randomized Clinical Trial.

The purpose of this study was to compare video modelling (VM) to a Picture Exchange Communication System (PECS) aimed at improving the oral hygiene of children with autism spectrum disorder (ASD). This prospectively stratified randomized controlled trial was conducted on 50 children with mild and moderate ASD. Children were assigned into two balanced groups.

Clinical Evaluation of CAD/CAM Ceramic Endocrown Versus Prefabricated Zirconia Crown in the Restoration of Pulpotomized Primary Molars: A Two-Year Spilt-Mouth Randomized Controlled Trial.

Objectives:  The current trial aimed to compare lithium disilicate (LS2) endocrowns' clinical performance, gingival health, and parental satisfaction to those of prefabricated zirconia crowns (ZCs) over a 24-month of follow-up.

Materials And Methods:  This study designed as a spilt-mouth randomized controlled trial. A total of 88 pulpotomized mandibular second primary molars of 44 children were assigned into two equal groups.

Premixed bioceramics versus mineral trioxide aggregate in furcal perforation repair of primary molars: in vitro and in vivo study.

Objectives: The current study was carried out to (1) evaluate premixed bioceramic (BC) and mineral trioxide aggregate (MTA) sealing properties in a laboratory and (2) compare the performance of these two materials in repairing an immediate iatrogenic furcal perforation of primary molars both clinically and radiographically.

Materials And Methods: In vitro sections including eighty mandibular second primary molars were sorted into 4 equal groups: (1) an intact furcation area group, (2) an artificial perforation group (unrepaired), (3) an artificial perforation group repaired with MTA, and (4) an artificial perforation group repaired with premixed BC. The dye extraction method was used to assess the sealing ability of the material.

Untreated dental caries prevalence and impact on the quality of life among 11 to14-year-old Egyptian schoolchildren: a cross-sectional study.

Background: This study aimed to assess caries prevalence and experience among 11 to 14 years, school children, analyze demographic, socioeconomic, personal and professional dental care in relation to untreated carious lesions, and evaluates the effect of decayed teeth on early adolescents' oral health-related quality of life (OHRQoL).

Methods: A cross-sectional analytical investigation was conducted on 1020 preparatory schoolchildren selected on the basis of a multistage sampling technique. Caries status of the participants detected via recording their caries experience and untreated cavities using DMFT and DT indices.

Oral-cancer knowledge, practice, and attitude assessment of dentists in Upper Egypt: A cross-sectional study.

The aims of this study were to investigate the knowledge, attitude, and practice of dentists in Upper Egypt with regard to oral cancer (OC). Out of 1,200 licensed dental practitioners list, 424 dentists were randomly selected from three governorates in Upper Egypt (Minia, Assuit, and Sohag). The sample size was calculated using the equation considering the knowledge of dentists about OC, confidence level, and margins of error; then, an additional number of dentists were added to guard against nonresponse.
