Purpose

The purpose of this review was to analyze existing literature on the relationship between tooth count and mortality by evaluating the findings in the context of methodological variations. We aimed at addressing the question of whether preserving natural teeth can impact mortality.

Study selection

PubMed, Web of Science and CINAHL databases were systematically searched using various combinations of related and synonymous keywords for “tooth count” and “mortality”. The references of included articles were also evaluated for inclusion. Overall 49 studies found to be eligible were critically evaluated and their key findings were summarized.

Results

Studies were conducted in various continents and differed substantially in regards to their sample size, population, methodology, the definition of the tooth count variable, the confounders as well as the mediators accounted for in the analysis. Follow-up period ranged from 1 to 56 years.

Conclusions

Although high variability in the studies precludes a definite conclusion about the relationship between number of teeth and mortality, the overall finding from this review is that reduced tooth count is associated with higher mortality. However the impact of factors such as smoking, health-care access, baseline co-morbidity and risk profile, dental and periodontal health, the presence of dental prosthesis as well as socio-economic status, in mediating whole or part of the association cannot be overlooked and needs further investigation using more standard methodologies. Any differences in males vs. females, as well as among different age groups, will also need further consideration in the future studies.  相似文献

This clinical report of a fractured cantilevered substructure bar describes an alternative treatment to the proposed refabrication of the substructure bar and overdenture prosthesis. This report outlines the clinical and laboratory procedures to repair the fractured bar, eliminating the time and expense of fabricating a new bar and prosthesis.  相似文献

In this 2-part review series, the current uses of saliva as a diagnostic fluid are reviewed, first with a focus on known measurements of systemic conditions. In Part 2, the role of saliva to measure bone turnover with a special emphasis on osteoporosis will be discussed.  相似文献

We present a curious pulsatile right atrial mass which we found by routine transthoracic echocardiography in an asymptomatic woman. Only consecutive section planes finally revealed the true nature of this round mass, highlighting the general statement that the ultrasonographer should never rely on a single ultrasound imaging plane for making a correct diagnosis.  相似文献
