Texte intégralStatement of the problem: In the living individual, the estimation of dental age is a parameter used in orthopedics or dentofacial orthodontics or in pediatrics to locate the individual on its growth curve. In forensic medicine, the estimation of dental age allows to infer the chronological age for a regression or a classification task. There are physical and radiological methods. While the latter are more accurate, there is no universal method. Demirjian created the most widely used radiological method almost 50 years ago, but it is criticized for its accuracy and for using reference tables based on a French-Canadian population sample. Objective: Artificial intelligence, and more particularly machine learning, has allowed the development of various tools with a learning capacity on an annotated database. The objective of this thesis was to compare the performance of different machine learning algorithms first against two classical methods of dental age estimation, and then between them by adding additional predictors. Material and method: In a first part, the different methods of dental age estimation on living children and young adults are presented. The limitations of these methods are exposed and the possibilities to address them with the use of machine learning are proposed. Using a database of 3605 panoramic radiographs of individuals aged 2 to 24 years (1734 girls and 1871 boys), different machine learning methods were tested to estimate dental age. The accuracies of these methods were compared with each other and with two classical methods by Demirjian and Willems. This work resulted in an article published in the International Journal of Legal Medicine. In a second part, the different machine learning methods are described and discussed. Then, the results obtained in the article are put in perspective with the publications on the subject in 2021. Finally, a perspective of the results of the machine learning methods in relation to their use in dental age estimation is made. Results: The results show that all machine learning methods have better accuracy than the conventional methods tested for dental age estimation under the conditions of their use. They also show that the use of the maturation stage of third molars over an extended range of use to 24 years does not allow the estimation of dental age for a legal issue. Conclusion: Machine learning methods fit into the overall process of automating dental age determination. The specific part of deep learning seems interesting to investigate for dental age classification tasks

Texte intégralSummary Aim: Pathomorphological changes of the temporomandibular joints occur frequently in patients with JIA. In this study, orthodontic two-dimensional X-ray imaging (orthopantomography - OPG) was used to differentiate pathological changes of the temporomandibular joints in JIA patients and to determine asymmetries of the mandible in accordance to the degree of condyle destruction. In addition, it should be examined how the disease duration affects the involvement of the temporomandibular joints. In addition, clinical analysis (FAL), joint vibration analysis (JVA) and 3D stereophotogrammetry (3d-scan) were used for the specific analysis of pathomorphology. The aim was to detect unambiguous parameters for affected temporomandibular joints by means of non-invasive, cost-effective and rapidly available examination methods. Patients and methods: In this study, 46 patients (28 female, 18 male) of Caucasian origin were diagnosed with JIA. The temporomandibular joints (n = 92) were individually evaluated based on the degree of their condylar destruction (Grades 0 - 4 according to Billiau et al. [78]) and divided into a slightly affected group 1 (Grades 0, 1 and 2 according to Billiau: radiologically unremarkable, Condylar erosions, condyle flattening) and into a severely affected group 2 (grade 3 and 4 according to Billiau: condyle flattening with erosions, complete loss of the condyle). To quantify mandibular asymmetries, the ratio of condyle, ramus and mandibular height was determined. The comparison of the individual clinical, instrumental and imaging examination procedures (OPG, FAL, JVA, 3d-Scan) was performed by comparing the severely affected and the slightly affected patient group. Results: Disease duration: Based on the degree of condylar destruction, 36 patients were divided into the slightly affected group 1 and 10 patients to the severely affected group 2. The disease duration was significantly longer in the severely affected patient group (8.9 ± 5.2 years) than in the slightly affected patient group (4.6 ± 4.7 years) (p = 0.031). FAL: The results of the FAL showed more functional deviations in the severely affected patient group (group 2). However, no significant difference to Group 1 was found. The severely affected patients showed a higher percentage of pain in palpation of the temporomandibular joints (group 2: 70.0% vs. group 1: 61.1%) or mouth opening pain (group 2: 10.0% vs. group 1: 8.3%), mandibular deflections (group 2: 50.0% vs. group 1: 33.3%), joint noises (group 2: 80.0% vs. group 1: 63.9%) and mouth opening restrictions (Group 2: 60.0% vs. Group 1: 25.0%). The average mouth opening in group 2 was 40.6 mm, while in group 1 it was 43.5 mm. In patients with a mouth opening <40 mm, an average mouth opening of 35.3 mm was measured in group 2 and 34.1 mm in group 1. JVA: In the joint-related as well as in the patient-group-related analysis of the JVA, the measurement parameters in the severely affected patient group increasingly pointed to chronic degenerative or existing effusions in the temporomandibular joint. In the joint-related evaluation, this was demonstrated in particular by a reduced signal strength in the severely affected patient group (total power: p = 0.005, power <300 Hz: p = 0.006, power> 300 Hz: 0.003;) and in a significantly increased peak frequency (p = 0.036). OPG: In the evaluation of the OPGs, the ratio of condyle, ramus and mandibular height was significantly lower in the severe patient group (ratio 79.6%, 85.9%, 86.5%) (condyle height: p = 0.0005; p = 0.0030, mandibular height: p = 0.0002), than in the slightly affected Patient group (ratio 93.8%, ratio 96.0%, 95.6%). Thus, significantly more pronounced mandibular asymmetries were found in the severely affected patient group than in the slightly affected patient group. 3d scan: In the 3d scan, deviations of the soft tissue chin from the median plane (group 2: 3.0 mm vs. group 1: 1.2 mm, p = 0.041) and mandibular asymmetry were significantly more frequent in patients with severely affected temporomandibular joints (group 2: 62.5% vs. Group 1: 14.8%, p = 0.015) than in patients with slightly affected temporomandibular joints. Conclusion: It has been shown that it is possible to visualize pathology in the temporomandibular joint by means of simple and easily available examination methods such as clinical functional analysis, joint vibration analysis and OPG imaging. The methods can serve as an important reference for controlling disease progression in patients with JIA. In addition, a classification of the condyles in severe and slightly affected temporomandibular joints by means of pathomorphological analysis is possible. There is a direct correlation between the degree of destruction, the extent of mandibular asymmetry and the duration of the disease in patients with JIA. Overall, the value of clinical, instrumental and imaging examination methods of temporomandibular joint diagnosis in patients with juvenile idiopathic arthritis was demonstrated
