Characterization of the Oral Microbiome Among Children With Type 1 Diabetes Compared With Healthy Children.

Current microbiome profiling of type 1 diabetes mellitus (T1D) patients is mostly limited to gut microbiome. We characterized the oral microbiome associated with T1D in children after the onset of the disease and explored its relationship with oral physiological factors and dental status. This cohort study comprised 37 children aged 5-15 years with T1D and 29 healthy children matched in age and gender.

Adherence to Infective Endocarditis Prevention Guidelines by Israeli Dentists Who Treat Children.

Purpose: To examine the rate of adherence of Israeli dentists who treat children and their rate of adherence, in 2010-2011 and in 2016, to changes made to the 2008 American Heart Association (AHA) guidelines for endocarditis prevention.

Methods: A questionnaire on adherence to AHA guidelines was handed out in two consecutive continuing education courses in 2010-2011 and again in 2016. Data were analyzed using student's t test, chi-square, and analysis of variance.

Age Related Prevalence of Pre-Eruptive Intracoronal Radiolucent Defects in the Permanent Dentition.

Objective: The present study aimed to determine if the prevalence of pre-eruptive intracoronal radiolucent defects is higher for young age groups, in which there are more unerupted teeth.

Study Design: A retrospective study of panoramic and bitewing radiographs was conducted. An inclusion criterion was the presence of un-erupted permanent teeth with a formed and clearly visible crown.

Are there metallic traces in black extrinsic dental stain?

Objective: The detection of ferric ions in samples of black extrinsic dental stain led to the idea that it is comprised of insoluble ferric compounds. The present study examined the chemical composition of black extrinsic dental stain.

Method And Materials: Plaque was collected from 17 children with black extrinsic dental stain (study group A) and from 15 children without black extrinsic stain (control group), using sterile graphite curettes; and from 4 children with black extrinsic stain (study group B), using a standard sterile metal curette.

Medical considerations in dental treatment of children with Williams syndrome.

Williams syndrome is a rare disorder that was first described in 1961. It is thought to be caused by a microdeletion in the long arm of chromosome 7 at 7q11.23 and is a multisystem, congenital, and panethnic disorder characterized by a number of developmental and physical abnormalities, including congenital cardiovascular abnormalities, mental retardation and neurological features, growth deficiency, genitourinary manifestation, gastrointestinal and musculoskeletal problems, behavioral characteristics, craniofacial features, ophthalmologic features, and dental problems.

Mutans streptococcus counts following treatment for early childhood caries.

Purpose: The purpose of the study was to assess mutans streptococci (MS) count in children who were treated for early childhood caries (ECC) in a follow-up examination.

Methods: Forty-four children who were treated for ECC in the pediatric dentistry clinic of the Hebrew University-Hadassah School of Dental Medicine were given paraffin film to chew. A blade containing children's saliva was placed inside a test tube containing MS selective medium to allow bacteria growth.
