The periodontal disease and gingival bleeding are highly prevalent in the adult population worldwide. The World Health Organization (WHO) data shows that 90–100% of the 34-year-old adults present gingival inflammation. Therefore, an investigation method is required to allow the assessment of the periodontal disease as well as the monitoring of the evolution of the gingival inflammation after periodontal treatments. Non-invasive and operator-independent methods for periodontal examination are necessary for diagnosing and monitoring the periodontal disease. The periodontal ultrasonography is a reliable technique for visualizing the anatomical elements which are necessary to diagnose the periodontal status. Using this imaging technique the dentino-enamel junction, the cortical bone, the radicular surface from the crown to the alveolar bone, the gingival tissue can be seen without interfering with those elements during the examination. Also, calculus visualization is possible before and after scaling in order to evaluate the quality of the treatment. Using 2D ultrasonography is not feasible in dental practice as it requires extensive experience and is also time consuming. The reproducibility of the 2D slices is very difficult in order to have the possibility to compare different investigations efficiently. 3D reconstructions of the periodontal tissue can be a very good alternative to eliminate the operator dependence. Ultrasonography allows the practitioner to visualize the anatomic elements involved in making a periodontal diagnosis. It also allows tracking of subsequent changes. This method is not commonly used for periodontal examination and further studies are required. Previous studies show that ultrasonography can be a reliable non-invasive method to diagnose and monitor the periodontal disease.

“…For orthodontic treatment, the alveolar bone pattern and crest thickness must be evaluated prior to treatment to avoid risk of alveolar bone loss during tooth movement (Timock et al 2011). At present, CBCT is currently the only radiographic method to visualize the bone level on the buccal and lingual surfaces (Nguyen, Pacheco-Pereira, et al 2018). The development of ultrasound techniques will minimize the patients’ exposure to ionizing radiation.…”

Alveolar Bone Segmentation in Intraoral Ultrasonographs with Machine Learning

et al. 2020

The use of intraoral ultrasound imaging has received great attention recently due to the benefits of being a portable and low-cost imaging solution for initial and continuing care that is noninvasive and free of ionizing radiation. Alveolar bone is an important structure in the periodontal apparatus to support the tooth. Accurate assessment of alveolar bone level is essential for periodontal diagnosis. However, interpretation of alveolar bone structure in ultrasound images is a challenge for clinicians. This work is aimed at automatically segmenting alveolar bone and locating the alveolar crest via a machine learning (ML) approach for intraoral ultrasound images. Three convolutional neural network–based ML methods were trained, validated, and tested with 700, 200, and 200 images, respectively. To improve the robustness of the ML algorithms, a data augmentation approach was introduced, where 2100 additional images were synthesized through vertical and horizontal shifting as well as horizontal flipping during the training process. Quantitative evaluations of 200 images, as compared with an expert clinician, showed that the best ML approach yielded an average Dice score of 85.3%, sensitivity of 88.5%, and specificity of 99.8%, and identified the alveolar crest with a mean difference of 0.20 mm and excellent reliability (intraclass correlation coefficient ≥0.98) in less than a second. This work demonstrated the potential use of ML to assist general dentists and specialists in the visualization of alveolar bone in ultrasound images.

“…La desventaja es que requiere personal capacitado para manipular el equipo, con suficiente conocimiento anatomopatológico para reconocer exitosamente las imágenes y que pueda realizar un diagnóstico preciso y diferenciar los fenómenos sonográficos. No hay muchos estudios científicos que respalden su uso en la odontología, puesto que ha sido utilizada más para la obtención de imágenes macro de tejidos blandos que en el caso de imágenes que requieran un análisis más minucioso y de tejidos duros ( 21,28 ).…”

La ecografía es una ayuda diagnóstica en el área de la salud que se usa para evaluar el desarrollo intrauterino, observar el comportamiento de lesiones, valorar órganos internos y acompañar procedimientos clínicos específicamente en la medicina, pero en la odontología es un campo en el que apenas se está explorando e incursionando para incluirlo como parte de los métodos diagnósticos de rutina en la consulta clínica. El creciente interés por investigar su uso como método diagnóstico y terapéutico en la odontología se basa en las bondades que tiene y en cómo puede facilitar muchos procesos por tratarse de una ayuda diagnóstica accesible, económica y poco nociva para la salud. En el presente artículo se exponen los diferentes usos que se le da a la ecografía en las diferentes especialidades odontológicas, y se la compara con otros métodos diagnósticos.
