PARAMETER SIGMOID TRANSFORM CONTRAST ENHANCEMENT FOR DENTAL RADIOGRAPH CLASSIFICATION AND NUMBERING SYSTEM

Dental record is a method that is used to identify a person. The identification process needs a system that could recognize each individual tooth automatically. The similar intensity level between the teeth and the gums is one of the main problem in tooth identification in a dental radiograph. The intensity problem could influence the segmentation process of the system. In this paper, we proposed a new contrast enhancement by using parameter sigmoid transform to increase the segmentation accuracy. There are five main steps in this method. The first step is to fix the contrast of the image with the proposed method. The next steps are to segment the teeth using horizontal and vertical integral projection, feature extraction, and classification using Support Vector Machine (SVM). The last step is teeth numbering. The experiment result using the proposed method have an accuracy rate of 88% for classification and 73% for teeth numbering

Aplicación de la inteligencia artificial en Odontología: Revisión de la literatura

The application of artificial intelligence (AI) in the dental field was reviewed in this article. The objective was to review the evidence on artificial intelligence and its application in the different dental specialties. A search was carried out on Medline/PubMed, Scopus and Web of Science databases from 2017 to 2021. Three hundred and twenty-one articles were found, of which 62 were selected and allowed the application of AI in six specialties: periodontology, implantology, forensic dentistry, oral medicine and pathology, orthodontics and diagnostic/cariology/endodontics. The specialty of diagnosis/caryology/ endodontics had more articles on the topic of AI and convolution neural network was the type of AI most used. It was concluded that AI is being widely used in dentistry showing promising results as they show an accuracy equivalent to that of different trained specialists and in some cases they overcome human errors showing excellent results.En este artículo se revisó sobre inteligencia artificial (IA) y su aplicación en el campo odontológico. El objetivo fue revisar la evidencia sobre inteligencia artificial y su aplicación en las diferentes especialidades odontológicas. Se realizó una búsqueda en las bases de datos de Medline/PubMed, Scopus y Web of Science desde el año 2017 al 2021. Se encontraron 321 artículos, de los cuales se seleccionaron 62, que mostraron la aplicación de la IA en seis especialidades: periodoncia, implantología, odontología forense, medicina y patología oral, ortodoncia y diagnóstico/cariología/endodoncia. Se encontró que la especialidad con más artículos sobre el tópico de IA fue la de diagnóstico/cariología/endodoncia y el tipo de inteligencia artificial que más se utilizó fue el de red neural convolucional. Se concluyó que la IA se está utilizando ampliamente en odontología demostrando resultados prometedores ya que muestran una precisión equivalente a la de diferentes especialistas capacitados y en algunos casos superan los errores humanos demostrando excelentes resultados
