Abstract

Objectives: To assess the influence of two conventional and one adapted cheek and lip retractors and three emissivity setting values on intraoral infrared thermography (IT) temperature values.

Methods: The sample was composed by 50 volunteers. Three cheek and lip retractors were tested: Group 1-flex retractor (FR); Group 2-FR adapted with Styrofoam; Group 3-U-type retractor (UR) for cheek and lip. All thermograms were acquired using FLIR T650 infrared camera. A set of three thermograms in frontal norm were acquired for each lip and cheek retractor at 0.91, 0.96, and 0.98ε, with an interval of 15 min between each set of images to avoid thermal interference. All images were assessed by two observers. The ROIs' mean temperature of the four upper incisors was recorded. Two-way ANOVA and Sidak post-test were used for data assessment with a significance level of 5%.

Results: Group 3 showed higher mean temperature than Groups 1 and 2 at all emissivity settings for all assessed teeth (P < .05). 0.91ε showed higher temperature than 0.96ε and 0.98ε for all assessed variables (P < .01). Contralateral teeth assessed using Group 3 at 0.91ε showed statistical differences between each other (P < .05). No statistical difference was observed between contralateral teeth assessed using Groups 1 and 2 at 0.96ε and 0.98ε (P > .05).

Conclusions: The choice of cheek and lip retractor and emissivity setting can interfere on intraoral IT temperature values. U-type cheek and lip retractor and 0.91ε setting should not be used for IT image acquisition when assessing dental tissues.

不同的颊唇牵开器和发射率对口内红外热成像的影响。

目的：评估两种传统和一种改良的颊唇牵开器以及三种发射率设置值对口内红外热成像温度值的影响：评估两种传统和一种经调整的面颊和嘴唇牵开器以及三种发射率设置值对口内红外热成像（IT）温度值的影响：样本由 50 名志愿者组成。测试了三种颊唇牵开器：第 1 组--柔性牵引器（FR）；第 2 组--用泡沫塑料改装的 FR；第 3 组--用于脸颊和嘴唇的 U 型牵引器（UR）。所有热图均使用 FLIR T650 红外热像仪采集。在 0.91、0.96 和 0.98 Ɛ处分别为唇部和颊部牵开器采集了三组正面标准的热图，每组图像之间间隔 15 分钟，以避免热干扰。所有图像均由两名观察者进行评估。记录四个上门牙 ROI 的平均温度。数据评估采用双向方差分析和 Sidak 后验，显著性水平为 5%：结果：在所有被评估牙齿的所有发射率设置下，第 3 组的平均温度均高于第 1 组和第 2 组（P 0.05）：结论：颊唇牵引器和发射率设置的选择会影响口内 IT 温度值。在评估牙齿组织时，不应使用 U 型颊唇牵引器和 0.91Ɛ 设定来获取 IT 图像。

期刊介绍： Dentomaxillofacial Radiology (DMFR) is the journal of the International Association of Dentomaxillofacial Radiology (IADMFR) and covers the closely related fields of oral radiology and head and neck imaging. Established in 1972, DMFR is a key resource keeping dentists, radiologists and clinicians and scientists with an interest in Head and Neck imaging abreast of important research and developments in oral and maxillofacial radiology. The DMFR editorial board features a panel of international experts including Editor-in-Chief Professor Ralf Schulze. Our editorial board provide their expertise and guidance in shaping the content and direction of the journal.
