نوع مقاله : مقاله‌های پژوهشی

چکیده

مقدمه: در این مطالعه موقعیت اپکس ریشه‌ی دندان‌های پره مولر دوم و مولر اول ماگزیلا با کف سینوس با استفاده از توموگرافی کامپیوتری با اشعه‌ی مخروطی (Cone beam computed tomography) CBCT بررسی گردید.
مواد و روش‌ها: در این مطالعه توصیفی- تحلیلی که در سال 1401 به انجام رسید، ۱۷۲ کلیشه‌ی  CBCTشامل دندان مولر اول و پره مولر دوم بیماران بخش رادیولوژی دانشکده‌ی دندان‌پزشکی دانشگاه آزاد اسلامی واحد اصفهان (خوراسگان) با سن 20 تا 60 سال بررسی شد. موقعیت اپکس دندان‌ها در پلن ساجیتال و کرونال بررسی گردید. وضعیت اپکس بر اساس فاصله تا کف سینوس به سه دسته OS (اپکس ریشه خارج کف سینوس)، CO (اپکس در تماس با کف سینوس) و  IS(اپکس داخل کف سینوس) تقسیم و توسط محقق، متخصص رادیولوژی و اندودانتیست بررسی و داده‌ها با آزمونMann-Whitney  در سطح خطای 0/05 آنالیز شد.
یافته ها: موقعیت OS، شایع‌ترین حالت اپکس ریشه‌های خلفی با کف سینوس بود. بیشترین میزان در دندان پره مولر دوم و کمترین در ریشه پالاتال مولر اول بالا بود. موقعیت IS بیشتر در ریشه‌ی پالاتال مولر اول و کمترین، ریشه پره مولر دوم بود. موقعیت CO، بیشتردر ریشه‌های مزیوباکال و دیستوباکال به طور مساوی مشاهده و کمترین درصد در دندان‌های پره مولر دوم دیده شد. اختلاف معنی‌داری در موقعیت اپکس ریشه‌ها نسبت به کف سینوس ماگزیلا بین زنان و مردان مشاهده نشد و سن تأثیری بر موقعیت اپکس ریشه‌های دندان‌ها نداشت (0/05 p value <).
نتیجه‌گیری: اپکس ریشه‌های مولر اول فک بالا نسبت به اپکس پره مولر دوم فک بالا نزدیکی بیشتری به سینوس داشتند. فراوانی ریشه‌هایی که اپکس آن‌ها با کف سینوس فاصله داشتند بیش از ریشه‌هایی بود که در داخل سینوس بودند.

Investigating the Position of the Apex of the Maxillary Second Premolar and First Molar With Sinus Floor by Cone Beam Computed Tomography Method

چکیده [English]

Introduction: In this investigation, the position of the root apex of the maxillary second premolar and first molar teeth with the sinus floor was investigated using the Cone beam computed tomography (CBCT) method.
Materials and Methods: In this descriptive-analytical study conducted in 2022-2023, 172 CBCT stereotypes were analyzed, including the first molar and second premolar of patients aged 20 to 60 at the radiology department of Isfahan Azad Dental School. The position of the apex of the teeth was checked in the sagittal and coronal planes. The state of the apex was divided into three categories based on the distance to the floor of the sinus: OS (root apex outside the sinus floor), CO (apex in contact with the sinus floor), and IS (apex inside the sinus floor) which reviewed by researchers, radiologists and endodontists, and the data were analyzed by Mann-Whitney test at the significance level of 0.05%.
Results: The OS position was the most common posterior root apex with a sinus floor. The highest amount was in the second premolar, and the lowest was in the palatal root of the upper first molar. IS position was most in the palatal root of the first molar and the least in the root of the second premolar. The position of the CO was observed predominantly in the mesiobuccal and distobuccal roots equally, and the lowest percentage was seen in the second premolar teeth. There was no significant difference in the position of the apex of the roots compared to the floor of the maxillary sinus between women and men, and age did not affect the position of the apex of the roots of the teeth (p value < 0.05).
Conclusion: The apex of the roots of the maxillary first molar is closer to the sinus than the apex of the maxillary second premolar. The frequency of the roots whose apex was far from the sinus floor was more than the roots that were inside the sinus.
