To find the association between the morphological characteristics of palatal rugae and sagittal skeletal patterns.
The retrospective charts review was conducted at the Aga Khan University Hospital from April to June 2016, and comprised data obtained from the pretreatment dental cast of orthodontic patients visiting the dental clinics over 5 years from 2011 to 2015. The sample was divided equally in three malocclusion groups based on sagittal skeletal relationship Class I, Class II and Class III. The number of palatal rugae was recorded for both right and left sides. Morphological features of the three anterior most primary rugae were recorded for the length, pattern and orientation bilaterally. SPSS 20 was used to compare the number and lengths as well as the pattern and orientation of palatal rugae among the groups.
Of the 165 subjects, there were 55(33.3%) in each of the three groups. Significant differences were recorded in rugae lengths among the groups at ruga 1 on both sides and rugae 2 and 3 on the left side (p<0.05 each). There were significant differences in the palatal rugae patterns among the groups (p<0.05) except at rugae 2 and 3 on the left side (p>0.05). Orientation showed significant differences at ruga 2 on the right side (p=0.02).
No specific pattern was associated with any skeletal pattern. Further studies are required to evaluate three-dimensional characteristics of rugae to assess the association between palatal rugae and sagittal skeletal patterns.
探究腭皱襞的形态特征与矢状骨面型之间的关联。
2016年4月至6月在阿迦汗大学医院进行回顾性病历审查，数据来自2011年至2015年这5年间到牙科诊所就诊的正畸患者的治疗前牙模。根据矢状骨面关系将样本平均分为安氏I类、安氏II类和安氏III类三个错颌组。记录左右两侧腭皱襞的数量。记录双侧最靠前的三条主要皱襞的长度、形态和走向等形态特征。使用SPSS 20对各组腭皱襞的数量、长度以及形态和走向进行比较。
165名受试者中，三组每组各有55名（33.3%）。各组间两侧的第1条皱襞以及左侧的第2条和第3条皱襞长度存在显著差异（均p<0.05）。除左侧的第2条和第3条皱襞外（p>0.05），各组间腭皱襞形态存在显著差异（p<0.05）。右侧第2条皱襞的走向显示存在显著差异（p = 0.02）。
未发现特定形态与任何骨面型相关。需要进一步研究来评估皱襞的三维特征，以评估腭皱襞与矢状骨面型之间的关联。
