Fluoridated dentifrice has been commercially available for the last 70 years. 1 Dentifrice use, that is the use of toothpastes or powders during oral hygiene practice, is a standard modality for preventative dental care. For high-risk children, the use of fluoridated dentifrice with parental supervision has a more significant caries-preventive effect compared with operatorapplied or unsupervised the use of fluoridated dentifrice. 2 In Australia, many dentifrice formulations marketed at children are sold in pharmacies and supermarkets. These include dentifrice with low strength, that is less than (<) 1000 parts per million (ppm) fluoride (F); standard strength, that is equal to or higher than (≥) 1000 ppm F; and non-fluoridated. Studies exploring the critical factors influencing the parental choice of child dentifrices are limited, region-specific and often exclude non-fluoridated dentifrice. 3,4 Swedish and Australian investigators have found no significant difference
Primate spaces are diastemata consistent with an inherent physiological pattern rather than functional adaptation. This article presents an atypically increased primate space only in the right mandibular arch. CPD/Clinical Relevance: Differential diagnoses that can be considered for an asymmetrically enlarged primate space include individual variation, tooth size, arch length discrepancy, infection, traumatic dental injury or an obstructive pathology, such as a malignant neoplasm, developmental cyst, odontoma or supernumerary tooth.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
