Linear dimensions of sella turcica were calculated and compared to those of a control group (47 individuals). A standardize scoring scale was used to quantify the extent of <jats:styled-content style="fixed-case">STB</jats:styled-content> from each radiographs.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>The frequency of partial and complete calcifications of sella in patients with dental anomalies is increased when compared to controls. <jats:styled-content style="fixed-case">STB</jats:styled-content> can influence the interclinoid distance but does not affect other linear dimensions of sella. No statistically significant difference has been found in sellar dimensions and <jats:styled-content style="fixed-case">STB</jats:styled-content> expression when evaluating radiographs at different ages.</jats:p></jats:sec><jats:sec><jats:title>Conclusions</jats:title><jats:p><jats:styled-content style="fixed-case">STB</jats:styled-content> is frequently found in patients with dental abnormalities.</jats:p></jats:sec>
