The Oral Microbiome in Treatment-Naïve Paediatric IBD Patients Exhibits Dysbiosis Related to Disease Severity that Resolves Following Therapy.

Background: There is a limited literature describing the oral microbiome and its diagnostic potential in paediatric inflammatory bowel disease [IBD].

Methods: We examined the dorsum tongue microbiome by V1-V2 sequencing in a cohort of 156 treatment-naïve children diagnosed with IBD compared to 102 healthy control children. Microbiome changes over time following treatment were examined in a subset of patients and associations between IBD diagnosis and dysbiosis were explored.

Timetable for oral prevention in childhood-a current opinion.

Dental caries in young children remains a public health problem particularly for children whose families are socioeconomically deprived. A child's first dental visit should be at approximately 12 months of age and this should facilitate the provision of anticipatory guidance concerning oral health and dental development to the child's parents/guardians. Compliance with dietary advice is of key importance and motivational interviewing shows promise in relation to parents adopting good oral health practices for their children.

Complete theoretical treatment of the transmittance ratio ultraviolet/visible spectrophotometric stray radiant energy test method.

This paper develops the theoretical basis behind the transmittance ratio test method for determining the relative stray radiant energy level in a double-beam dispersive spectrophotometer so as to allow for the non-transparency of a test solution towards the stray radiant energy for all sample beam-to-reference beam cuvette path length ratios. Non-transparency is defined as the transmittance of the reference beam solution, whose monochromatic absorbance is unity, towards stray radiant energy. The proposed method has the same concentration absorbing sample placed in the beams of the scanning spectrophotometer, the sample-beam cuvette being a known factor longer than the reference-beam cuvette.

Looking in the mouth for Crohn's disease.

It is widely acknowledged among gastroenterologists that the oral cavity may be involved in Crohn's disease (CD). However, the specific manifestations are poorly appreciated. Although oral aphthous ulceration is probably not diagnostically useful in patients with suspected CD, disease-specific manifestations do occur and are particularly common in children presenting with CD.

Aspiration of an avulsed primary incisor: a case report.

This case report describes a 7-year-old boy who avulsed and inhaled a primary maxillary incisor. Over the next number of weeks, he developed a persistent, productive cough, which was unresponsive to antibiotic therapy. Radiographic examination revealed a small radiopaque tooth-shaped object in the right hilar lung region.

Cleft palate and congenital synechiae syndrome: a case report.

A 1-day-old baby girl with a cleft of the secondary palate and a soft tissue band connecting the upper and lower jaws and preventing mouth opening was referred to the cleft lip and palate team by her pediatrician. This case represents a further example of an interesting but rare anomaly known as congenital alveolar synechia syndrome that requires early management to allow normal feeding and oral development.
