A Bag of Marbles: A Fascinating Compound Odontoma of the Maxilla.

Odontomas are the most common odontogenic tumors, typically diagnosed during the first two decades of life. 1 The purpose of this paper was to report an interesting case of an eight-year-old Caucasian boy who presented with an asymptomatic, progressive, firm swelling of the right maxilla with no eruption of the permanent maxillary right lateral incisor. Radiographic investigation revealed a mixed radiolucent and radiopaque lesion measuring 28 by 24 by 17 mm with a corticated border causing expansion and thinning of the buccal cortical plate.

Transcriptomic analysis of three Veillonella spp. present in carious dentine and in the saliva of caries-free individuals.

Veillonella spp. are predominant bacteria found in all oral biofilms. In this study, a metatranscriptomic approach was used to investigate the gene expression levels of three oral Veillonella spp.

Salivary levels of Bifidobacteria in caries-free and caries-active children.

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.

The use of multidirectional cross-sectional tomography for localizing an odontome.

Background: A 7-year old boy was referred with retained maxillary right primary central and lateral incisors. Radiographic exam revealed a large calcified radio-opaque mass overlying the roots of these primary teeth preventing the permanent teeth from erupting.

Case Report: The purpose of this paper is to describe the pre-operative use of multi-directional cross-sectional tomography in establishing the relationship between a large complex odontome that was preventing the eruption of a maxillary permanent central incisor.

Odontomas in the primary dentition: literature review and case report.

Odontomas are hamartomatous developmental malformations of dental tissues. They are very rarely diagnosed in the primary dentition. The purpose of this paper was to review the literature in relation to odontomas in the primary dentition, and describe the dental management of a child, age 4 years and 8 months, who had a complex odontoma.
