Assessing the reliability of ChatGPT: a content analysis of self-generated and self-answered questions on clear aligners, TADs and digital imaging

ABSTRACT Introduction: Artificial Intelligence (AI) is a tool that is already part of our reality, and this is an opportunity to understand how it can be useful in interacting with patients and providing valuable information about orthodontics. Objective: This study evaluated the accuracy of ChatGPT in providing accurate and quality information to answer questions on Clear aligners, Temporary anchorage devices and Digital imaging in orthodontics. Methods: forty-five questions and answers were generated by the ChatGPT 4.0, and analyzed separately by five orthodontists. The evaluators independently rated the quality of information provided on a Likert scale, in which higher scores indicated greater quality of information (1 = very poor; 2 = poor; 3 = acceptable; 4 = good; 5 = very good). The Kruskal-Wallis H test (p< 0.05) and post-hoc pairwise comparisons with the Bonferroni correction were performed. Results: From the 225 evaluations of the five different evaluators, 11 (4.9%) were considered as very poor, 4 (1.8%) as poor, and 15 (6.7%) as acceptable. The majority were considered as good [34 (15,1%)] and very good [161 (71.6%)]. Regarding evaluators' scores, a slight agreement was perceived, with Fleiss's Kappa equal to 0.004. Conclusions: ChatGPT has proven effective in providing quality answers related to clear aligners, temporary anchorage devices, and digital imaging within the context of interest of orthodontics.

RESUMO Introdução: A Inteligência Artificial (IA) é uma ferramenta que já faz parte de nossa realidade, e esta é uma oportunidade de entendermos como ela pode ser útil na interação com os pacientes e no fornecimento de informações valiosas sobre Ortodontia. Objetivo: O objetivo deste estudo foi avaliar a precisão do ChatGPT em responder a perguntas sobre Alinhadores transparentes, Dispositivos de ancoragem temporária, e Imagens digitais em Ortodontia. Métodos: 45 perguntas e respostas foram geradas pelo ChatGPT 4.0 e analisadas separadamente por cinco ortodontistas que, de forma independente, avaliaram a qualidade das informações fornecidas, usando uma escala de Likert, na qual pontuações mais altas indicavam uma maior qualidade das informações (1 = muito ruim; 2 = ruim; 3 = aceitável; 4 = bom; 5 = muito bom). Aplicou-se o teste H de Kruskal-Wallis (p < 0,05) e comparações pareadas post-hoc com correção de Bonferroni. Resultados: Das 225 avaliações dos cinco avaliadores diferentes, 11 (4,9%) foram consideradas como muito ruins, 4 (1,8%) como ruins, e 15 (6,7%) como aceitáveis. A maioria foi considerada boa [34 (15,1%)] ou muito boa [161 (71,6%)]. Com relação às pontuações dos avaliadores, percebeu-se uma leve concordância, com o Kappa de Fleiss igual a 0,004. Conclusões: O ChatGPT mostrou eficácia em fornecer respostas de qualidade para questões relacionadas a Alinhadores transparentes, Dispositivos de ancoragem temporária e Imagens digitais.

Mandibular Molar Protraction with Orthodontic Temporary Anchorage Devices: A Case Report.

Management of patients with congenitally missing mandibular second premolars continues to challenge clinicians to find the best treatment options. The Orthodontist must make the proper decision at the appropriate time regarding management of the edentulous space. If space is left for an eventual prosthetic replacement, the clinician should try to create the exact amount of space required and leave the alveolar ridge in an ideal condition for the future restoration. If the space is to be closed orthodontically, detrimental changes to the occlusion and facial profile must be prevented. Therefore, the correct decision must be made at the appropriate time. This paper presents a case report of a congenitally missing lower left second premolar where molar protraction with orthodontic temporary anchorage device has been done.

Evaluation of mandibular cortical bone thickness for placement of temporary anchorage devices (TADs) / 대한치과교정학회지

OBJECTIVE: In this study, we measured the cortical bone thickness in the mandibular buccal and lingual areas using computed tomography in order to evaluate the suitability of these areas for application of temporary anchorage devices (TADs) and to suggest a clinical guide for TADs. METHODS: The buccal and lingual cortical bone thickness was measured in 15 men and 15 women. Bone thickness was measured 4 mm apical to the interdental cementoenamel junction between the mandibular canine and the 2nd molar using the transaxial slices in computed tomography images. RESULTS: The cortical bone in the mandibular buccal and lingual areas was thicker in men than in women. In men, the mandibular lingual cortical bone was thicker than the buccal cortical bone, except between the 1st and 2nd molars on both sides. In women, the mandibular lingual cortical bone was thicker in all regions when compared to the buccal cortical bone. The mandibular buccal cortical bone thickness increased from the canine to the molars. The mandibular lingual cortical bone was thickest between the 1st and 2nd premolars, followed by the areas between the canine and 1st premolar, between the 2nd premolar and 1st molar, and between the 1st molar and 2nd molar. CONCLUSIONS: There is sufficient cortical bone for TAD applications in the mandibular buccal and lingual areas. This provides the basis and guidelines for the clinical use of TADs in the mandibular buccal and lingual areas.

Efectividad del anclaje esquelético temporal para el cierre de espacios: Revisión sistemática de literatura / Effectiveness of temporary skeletal anchorage for space closure:A systematic review

Introducción y Objetivo: El manejo del anclaje es fundamental para el éxito del tratamiento en ortodoncia fi ja, sin embargo no hay consenso acerca de la efectividad del anclaje esquelético para la retracción de los dientes anteriores. El objetivo fue evaluar la efectividad del anclaje esquelético para el cierre de espacios en el arco maxilar.Materiales y Métodos: Se realizó una revisión sistemática de literatura a partir de las bases de datos PubMed, Lilacs, Cochrane, Scielo. Se incluyeron ensayos clínicos controlados, donde el anclaje esquelético fuera utilizado para el cierre de espacios; tresrevisores analizaron los resúmenes y textos completos para considerar el cumplimiento de los criterios de inclusión y exclusión de manera independiente, en un formato de extracción de datos.Resultados: Se identifi caron 324 artículos, de los cuales 316 fueron rechazados después de la evaluación, de los ocho estudios inicialmente seleccionados, cinco fueron excluidos. Sólo tres estudios cumplieron con los criterios de inclusión. Se realizó un metanálisis con el método de efectos aleatorios para el movimiento mesial del molar superior, en el cual los dispositivos de anclaje esquelético temporal mostraron ser más efectivos en el control del anclaje en -2,72 mm (-4,10,- 1,33 IC95%) al compararlos con los métodos de anclaje ortodóntico convencional, esta diferencia fue estadísticamente signifi cativa. Conclusiones: El anclaje esquelético temporal parece ser más efectivo para controlar el movimiento mesial del molar durante el cierre de espacios, comparado con el anclaje ortodóntico convencional, sin embargo la evidencia científi ca en la literatura es escasa.

Introduction and Objetive: Anchorage management is essential for successful fi xed orthodontic treatment; however there is no consensus about the effectiveness of skeletal anchorage for anterior teeth retraction. The aim of this review was to evaluate the effectiveness of skeletal anchorage forspace closure in the maxillary arch. Materials and Methods: A systematic review of the literature was performed in PubMed, Cochrane, Lilacs, Scielo databases. Controlled clinical trials were included, where skeletal anchorage was used for space closure. Three reviewers examined the abstracts and full texts to determine fulfi llment of the inclusion and exclusion criteria independently in a data extraction form. Results: 324 papers, out of which 316 were excluded after the evaluation of title and abstract of the eight initially selected trials. Only three trials met the inclusion criteria.A meta-analysis was performed with a random effects method for the mesial movement of upper molars in which the temporary skeletal anchorage devices showed to be more signifi cantly moreeffective in controlling anchorage -2,7 mm (-4,10,-1,33 CI 95%) when compared to the conventionalanchorage control methods.Conclusions: Temporary skeletal anchorage seems to be more effective in controlling the movement of molars during mesial space closure, when compared to the conventional orthodontic anchorage although evidence in the literature is limited.
