Clinical examination revealed grade III mobile 71 and 81, with minimal

gingival inflammation and plaque deposits. There were no other dental findings and no significant medical history. Tooth numbers 71 and 81 exfoliated prematurely with no evidence of root resorption, shortly after presentation. Everolimus clinical trial Haematological and urinary investigations showed no abnormalities. Histological examination showed a complete absence of cementum. A diagnosis of OHP was made. After 10 months of dental follow-up, no further teeth have increased mobility. Conclusion.  Odontohypophosphatasia should be included as a differential diagnosis in children presenting with early loss of primary teeth. The dentist may be the first health care professional to whom the patient presents. “
“International Journal of Paediatric Dentistry 2013; 23: 32–38 Background  Salivary levels of Bifidobacteria have been shown to be significantly correlated with caries experience in adults but not as yet in children. Hypothesis.  Salivary levels of Bifidobacteria are

positively associated with caries experience in children. Aim.  To compare the salivary concentrations of Bifidobacteria of caries-free and caries-active children. Design.  Saliva was collected using the tongue-loop method from 38 caries-active children and from 22 clinically caries-free children, and the numbers of Bifidobacteria, mutans streptococci, lactobacilli and yeasts were determined. Additionally, the age and gender of the children, a plaque index, sugar amount in diet, sugar frequency in diet, hygiene practice and fluoride toothpaste usage were recorded. Results.  Bifidobacteria C59 wnt mw were isolated from 95% of the caries-active children and from only 9% of the caries-free children (P < 0.001). Salivary levels of Bifidobacteria Selleckchem Pembrolizumab were significantly correlated with amount of sugar in the diet, frequency of sugar consumption and oral hygiene practice. The significant variables that discriminated between the caries-free and caries-active subjects were salivary levels of Bifidobacteria, salivary levels of mutans streptococci

and oral hygiene practice (χ2 = 72.57, P < 0.001) and overall 90.0% of cases were correctly classified. Conclusions.  Salivary levels of Bifidobacteria are significantly associated with caries experience in children. The salivary levels of this genus may be a useful marker of caries risk. "
“This study aims to identify the determinants of caries prevention-oriented practice for children among final-year dental students in Nigeria. A questionnaire was distributed to 179 final-year dental students in six dental schools in Nigeria. It requested information on age, gender, knowledge of caries prevention measures, self-perceived competency in providing caries-preventive care for children, and caries prevention-oriented practice for two hypothetical cases with high and low risk of caries.
