The surface area was significantly different among groups, denoting higher values for stage B and C (1.82&lt;!--&gt; &lt;!--&gt;±&lt;!--&gt; &lt;!--&gt;0.55&lt;!--&gt; &lt;!--&gt;cm&lt;sup&gt;2&lt;/sup&gt; and 1.86&lt;!--&gt; &lt;!--&gt;±&lt;!--&gt; &lt;!--&gt;0.41&lt;!--&gt; &lt;!--&gt;cm&lt;sup&gt;2&lt;/sup&gt;, respectively), compared to stage D and E groups (1.53&lt;!--&gt; &lt;!--&gt;±&lt;!--&gt; &lt;!--&gt;0.38&lt;!--&gt; &lt;!--&gt;cm&lt;sup&gt;2&lt;/sup&gt; and 1.57&lt;!--&gt; &lt;!--&gt;±&lt;!--&gt; &lt;!--&gt;0.54&lt;!--&gt; &lt;!--&gt;cm&lt;sup&gt;2&lt;/sup&gt;, respectively). A significant negative but poor correlation was seen between mid-palate total average height, surface area and mid-palatal suture stage (rho&lt;!--&gt; &lt;!--&gt;=&lt;!--&gt; &lt;!--&gt;–0.278, &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;=&lt;!--&gt; &lt;!--&gt;0.005 and rho&lt;!--&gt; &lt;!--&gt;=&lt;!--&gt; &lt;!--&gt;–0.222, &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;=&lt;!--&gt; &lt;!--&gt;0.027, respectively). Moreover, a very strong to moderate positive correlation (rho&lt;!--&gt; &lt;!--&gt;=&lt;!--&gt; &lt;!--&gt;0.847, &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;&lt;&lt;!--&gt; &lt;!--&gt;0.001, rho&lt;!--&gt; &lt;!--&gt;=&lt;!--&gt; &lt;!--&gt;0.739, &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;&lt;&lt;!--&gt; &lt;!--&gt;0.001) was seen between age and the maturational stage of the mid-palatal and transverse palatine sutures, respectively. Both the mid-palatal and transverse palatine sutures maturity stages were positively and very strongly correlated (rho&lt;!--&gt; &lt;!--&gt;=&lt;!--&gt; &lt;!--&gt;0.839, &lt;em&gt;P&lt;/em&gt; &lt;!--&gt;&lt;&lt;!--&gt; &lt;!--&gt;0.001).&lt;/div&gt;&lt;/div&gt;&lt;div&gt;&lt;h3&gt;Conclusions&lt;/h3&gt;&lt;div&gt;The height and surface","PeriodicalId":45449,"journal":{"name":"International Orthodontics","volume":"23 1","pages":"Article 100935"},"PeriodicalIF":1.8,"publicationDate":"2024-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142510123","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
