Desafíos en la vigilancia de todos los casos de cáncer en Chile: Registro Nacional de Cáncer / Challenges in surveillance of all cancer cases: The Chilean National Cancer Registry

El cáncer causa millones de muertes a nivel mundial por lo que su registro es fundamental, existiendo registros clínicos, hospitalarios y poblacionales. Estos últimos son el estándar de oro para la información sobre incidencia y supervivencia de cáncer en una región definida. En Chile se cuenta con cinco registros poblacionales ubicados en ciertas zonas del país. El Registro Nacional del Cáncer chileno surge como un desafío para conformar una herramienta transversal a los tres tipos de registro con la finalidad de, al menos, conocer la cantidad de casos por tipo de cáncer. Su diseño implicó un despliegue de acciones orientadas a lograr consensos entre diversos actores respecto de la información, validación y eventos necesarios de registrar. Se identificaron cuatro etapas en el proceso de atención y el registro: sospecha de diagnóstico, confirmación morfológica (biopsia), resolución clínica (comité oncológico incluyendo la indicación de tratamiento), tratamiento y seguimiento oncológico. A su vez, el desarrollo de la plataforma (años 2018 a 2021) implicó levantamiento de información y acuerdos sobre los requerimientos para el co-diseño del registro, incluyendo un exitoso pilotaje con más de 20 establecimientos de salud del sector público y privado con registro de cerca de 7500 casos de cáncer. El despliegue y uso del Registro Nacional de Cáncer a nivel nacional depende de la autoridad sanitaria. Se trata de un sistema de información que recolecta, almacena, procesa y analiza de forma continua y sistemática datos sobre todos los casos y tipos de cánceres que ocurren en el país. En este trabajo se presenta el diseño y desarrollo de la herramienta, los desafíos abordados, sus fortalezas y debilidades.

Cancer causes millions of deaths worldwide, making its registration essential. There are clinical, hospital, and population-based registries in place. The latter is the gold standard for information on cancer incidence and survival in a defined region. Chile has five population-based registries located in specific areas of the country. The Chilean National Cancer Registry emerged with the challenge of creating a tool encompassing all three types of registries to identify the number of cancer cases by type. Its design involved a series of actions to achieve consensus among various actors regarding information, validation, and events to be registered. Four stages were identified in the care and registration process: suspected diagnosis, morphological confirmation (biopsy), clinical resolution (oncology committee, including treatment recommendations), treatment, and oncological follow-up. The platform's development (from 2018 to 2021) involved gathering information and agreements on the requirements for co-designing the registry, including a successful pilot program with over 20 public and private healthcare facilities that recorded nearly 7500 cancer cases. The deployment and use of the National Cancer Registry at a national level depends on the healthcare authority. It is an information system that continuously and systematically collects, stores, processes, and analyzes data on all cancer cases and types occurring in the country. This work presents the design and development of the tool, the challenges addressed, as well as its strengths and weaknesses.

Se destaca una situación intensa donde se manifiestan los tres niveles analíticos del marco teórico. Materiales y métodos: Investigación cualitativa de la transcripción de los diálogos sostenidos en WhatsApp entre 239 médicos intensivistas al inicio de la pandemia, específicamente a lo largo del 27 de febrero del 2020. Se utilizó el análisis narrativo para interpretar el fragmento del chat. Se elaboró un esquema con tres dimensiones (análisis de la información compartida, estándares de acción social en la atención a pacientes COVID-19 y expresiones emocionales) para codificar y categorizar los diálogos. Resultados: Los intercambios comunicativos por WhatsApp permitieron dar sentido al conocimiento emergente sobre la COVID-19 expuesto en las tramas narrativas. También influyó en la orientación de acciones pertinentes en los contextos hospitalarios y ayudó a modular las emociones ante la pandemia. Además, fomentó lazos de solidaridad y empatía entre los médicos intensivistas para afrontar con resiliencia el sufrimiento personal y social. Conclusiones: Los diálogos del chat reflejaron las relaciones humanas y las profundas inquietudes de las personas en situaciones de crisis. El estudio permitió comprender las formas y los significados de los intercambios comunicativos con el uso de dispositivos tecnológicos en tiempos de crisis para orientar la implementación de acciones en situaciones emergentes como la pandemia de la COVID-19. El WhatsApp respondió a la necesidad de información, con datos científicos y verídicos, sobre la pandemia. Se apreció que los médicos intensivistas se beneficiaron de la mensajería instantánea al cooperar en situaciones y experiencias críticas en el marco de una crisis sanitaria en evolución.

ABSTRACT Objective: To describe and analyze, at various levels, the communication exchanges that took place in a group chat of intensivists using the instant messaging application WhatsApp during the first stage of the COVID-19 pandemic, specifically on the day the first case was confirmed in Mexico. An intense situation showing the three dimensions of the theoretical framework is stood out. Materials and methods: A qualitative research of WhatsApp messages shared between 239 intensivists at the beginning of the pandemic, specifically throughout February 27, 2020. A narrative analysis was used to interpret a fragment of a chat. A schema with three dimensions (analysis of shared information, standards of social action in COVID-19 patient care and emotional expressions) was developed to code and classify the messages. Results: The communication exchanges via WhatsApp made it possible to give meaning to the emerging knowledge about COVID-19 in the narrative plots. They also influenced the implementation of appropriate actions in hospital environments and helped modulate emotions in front of the pandemic. In addition, it fostered bonds of solidarity and empathy between intensivists to face personal and social suffering with resilience. Conclusions: The chat messages reflected human relationships and the deep concerns of people in crisis situations. The study provided insight into the forms and meanings of communication exchanges with the use of technological devices in times of crisis to guide the implementation of actions in emerging situations such as the COVID-19 pandemic. WhatsApp responded to the need for information, with scientific and truthful data, about the pandemic. It was noted that intensivists benefited from instant messaging by cooperating in critical situations and experiences within the context of an evolving health crisis.

Occlusion development after premature loss of deciduous anterior teeth: preliminary results of a 24-month prospective cohort study

ABSTRACT Objective: This study aimed to evaluate occlusion development after premature loss or extraction of deciduous anterior teeth, by means of a prospective cohort study. Methods: Fifteen infants and children aged 1 to 5 years old were longitudinally assessed (with loss or extraction of deciduous anterior teeth [n = 9], and without tooth losses [n = 6]). Photographs and dental casts at the baseline and after 24 months of follow-up were performed. Dental casts were scanned, and linear measurements were made on the digitalized models (missing tooth space, arch perimeter, arch length, arch width, intercanine length and intercanine width). The t-test was used for groups comparisons (α = 0.05). Results: Individuals' mean age at baseline was 2.93 (± 1.18) years. No statistically significant differences were observed in the missing tooth space in the group with tooth loss during the 24 months of follow-up (p > 0.05). Arch perimeter, arch length, arch width, intercanine length and intercanine width did not show differences between the groups (p > 0.05). Qualitative photographic evaluation revealed other changes in the dental arches and occlusion, such as exfoliation and eruption of deciduous teeth, eruption of permanent teeth, self-correction or establishment of malocclusion, among others. Conclusion: The results suggest that the premature loss of deciduous anterior teeth does not affect the perimeter, length and width of the dental arches; however, other alterations that lead to malocclusion could be established.

RESUMO Objetivo: Este estudo teve como objetivo avaliar o desenvolvimento da oclusão após perda prematura ou extração de dentes decíduos anteriores, por meio de um estudo de coorte prospectivo. Métodos: Quinze bebês e crianças de 1 a 5 anos foram avaliados longitudinalmente (com perda ou extração de dentes anteriores decíduos [n = 9] e sem perdas dentárias [n = 6]). Foram realizadas fotografias e modelos dentais no início e após 24 meses de acompanhamento. Os modelos dentários foram escaneados e medidas lineares foram feitas nos modelos digitalizados (espaço dentário perdido, perímetro da arcada, comprimento da arcada, largura da arcada, comprimento intercaninos e largura intercaninos). O teste t foi utilizado para comparações entre grupos (α = 0,05). Resultados: A média de idade dos indivíduos no início do estudo foi de 2,93 (± 1,18) anos. Não foram observadas diferenças estatisticamente significativas no espaço dentário perdido no grupo com perda dentária durante os 24 meses de acompanhamento (p > 0,05). O perímetro da arcada, comprimento da arcada, largura da arcada, comprimento intercaninos e largura intercaninos não apresentaram diferenças entre os grupos (p> 0,05). A avaliação fotográfica qualitativa revelou alterações nas arcadas dentárias e na oclusão, como: esfoliação e erupção de dentes decíduos, erupção de dentes permanentes, autocorreção ou estabelecimento de má oclusão, entre outras. Conclusão: Os resultados sugerem que a perda prematura de dentes anteriores decíduos não afeta o perímetro, comprimento e largura das arcadas dentárias; entretanto, outras alterações que levam à má oclusão poderiam ser estabelecidas.

Utilização de dispositivos digitais, funcionamento familiar e desenvolvimento da linguagem em crianças de idade pré-escolar: um estudo transversal / Use of digital devices, family functioning, and language development in preschool children: a cross-sectional study

RESUMO Objetivo Este estudo teve como objetivo analisar a relação entre a utilização de dispositivos digitais, o funcionamento familiar e o desenvolvimento da linguagem em crianças de idade pré-escolar. Método Estudo transversal, descritivo-correlacional com uma amostra de 93 díades pais-crianças. As crianças tinham uma média etária de 57,01 ± 9,95 meses, sendo a maioria do gênero feminino. Os instrumentos de recolha de dados incluíram um questionário sobre o uso de dispositivos digitais, a versão portuguesa da Escala de Avaliação da Flexibilidade e Coesão Familiar - Versão IV (FACES-IV) e o Teste de Linguagem - Avaliação de Linguagem Pré-Escolar (TL-ALPE). Resultados As respostas demonstram uma maior tendência para a utilização do smartphone, tablet e televisão entre 0 e 3 horas por dia nas crianças. Com a aplicação da FACES-IV e do TL-ALPE, verificou-se que a maioria das famílias participantes eram do tipo equilibrado e que a maioria das crianças apresenta um normal desenvolvimento da linguagem. Observaram-se relações estatisticamente significativas entre a FACES-IV e o TL-ALPE; a FACES-IV e a utilização de dispositivos digitais; a utilização de dispositivos digitais e o TL-ALPE. Verificou-se que crianças com um funcionamento familiar mais equilibrado pontuam mais alto nas provas do TL-ALPE e que o tempo de uso de dispositivos digitais pode comprometer o desenvolvimento da linguagem. Conclusão Destaca-se o impacto da utilização dos dispositivos digitais e o papel do funcionamento familiar no desenvolvimento da linguagem da criança, sugerindo que uma utilização moderada de dispositivos digitais e um funcionamento familiar equilibrado são fatores facilitadores de um bom desenvolvimento da linguagem.

ABSTRACT Purpose This study aimed to analyse the relationship between the use of digital devices, family function, and language development in preschool children. Methods This cross-sectional, descriptive-correlational study included a sample of 93 parent-child dyads. The children were of an average age of 57.01 ± 9.95 months, and the majority were female. The data collection instruments included a questionnaire on the use of digital devices, the Portuguese version of the Family Flexibility and Cohesion Evaluation Scale - Version IV (FACES-IV), and a Preschool Language Test (TL-ALPE). Results The findings showed a greater tendency of children to use smartphones, tablets, and television for 0-3 hours daily. The analysis of the responses on the FACES-IV and TL-ALPE instruments showed that most of the participating families were of the balanced type and that most children had normal language development. Statistically significant relationships were found between the FACES-IV subscales and TL-ALPE subtests, FACES-IV subscales and the use of digital devices, and the use of digital devices and TL-ALPE subtests. Notably, children in more balanced family functioning scored higher on TL-ALPE tests, and the time spent using digital devices may compromise language development. Conclusion This study highlights the impact of digital device use and the role of family functioning on children's language development, suggesting that moderate digital device use and balanced family functioning are facilitating factors for good language development.

Medidas de proteção contra a COVID-19: impactos comunicativos, sociais e emocionais em usuários de aparelhos de amplificação sonora individual / Protective measures against COVID-19: communicative, social and emotional impacts on hearing aids users

RESUMO Objetivo investigar os impactos comunicativos, sociais e emocionais gerados pela adoção de medidas protetivas contra a COVID-19 e associá-los ao grau da perda auditiva e ao tempo de uso dos aparelhos de amplificação sonora individual. Métodos estudo transversal e quantitativo, com 72 indivíduos, divididos em adultos e idosos, com perda auditiva bilateral, de grau até moderadamente severo, protetizados antes da pandemia em um programa público de saúde auditiva e que mantiveram uso efetivo dos dispositivos. Os sujeitos foram convidados a participar do estudo enquanto aguardavam consulta. Os prontuários foram acessados, a fim de coletar informações sobre o perfil audiológico e adaptação/uso dos aparelhos de amplificação sonora individual. Em sala silenciosa, foi aplicado, oralmente, protocolo contendo questões objetivas e os dados foram tabulados e submetidos aos testes estatísticos Igualdade de Duas Proporções e Qui-Quadrado. Resultados nos dois grupos, um número significativo de usuários teve a comunicação impactada pelo uso de máscaras e pelo distanciamento físico, predominando, entre os adultos, a dificuldade com as tecnologias digitais (celulares/computadores), enquanto nas videochamadas, os prejuízos comunicativos foram mais experenciados pelos idosos. Os empecilhos comunicativos e sociais existiram, independentemente do perfil audiológico e do tempo de uso dos dispositivos. Quando questionados se deixaram de se comunicar e se as medidas afetaram a sua vida social, as respostas ficaram divididas entre "sim/às vezes" e "não". Quanto ao impacto emocional das medidas protetivas, constatou-se maior repercussão entre os adultos. Conclusão as medidas protetivas afetaram a comunicação dos usuários de aparelhos de amplificação sonora individual, porém, não desencorajaram as trocas comunicativas e as interações sociais de, aproximadamente, metade da amostra, sendo o impacto emocional mais evidente nos adultos. Tais dificuldades não estiveram relacionadas ao perfil audiológico e uso diário dos dispositivos.

ABSTRACT Purpose to investigate the communicative, social, and emotional impacts generated by adopting protective measures against COVID-19 and associate them with the degree of hearing loss and the time of use of hearing aids. Methods cross-sectional quantitative study, with 72 individuals, divided into adults and older adults, with bilateral hearing loss up to moderately severe degree, users of hearing aids fitted before the pandemic in a public hearing health program who had maintained effective use of the devices. The participants were invited to participate in the study while waiting for an appointment and signed the consent form. After that, medical records were accessed to collect information about audiological profiles and the fitting/use of hearing aids. Afterward, a protocol with objective questions was orally applied in a silent room. Data were tabulated and subjected to Equality of Two Proportions and Chi-Square statistical tests. Results in both groups, a significant number of users had communication impacted by the use of masks and by social distancing, with difficulty with digital technologies (cell phones/computers) predominating among adults, while older adults more commonly experienced communicative impairments during video calls. The communicative impediment existed regardless of the audiological profile and device use time. When asked if they stopped communicating and if the measures affected their social life, the sample was divided between "yes/sometimes" and "no". As for the emotional impact of protective measures, there was a greater impact among adults. Conclusion protective measures affected the communication of hearing aids users but did not discourage communicative exchanges and social interactions for approximately half of the sample, with the emotional impact being more evident in adults. Such difficulties were not related to the audiological profile and daily use of the devices.

Do baseline participant characteristics impact the effectiveness of a mobile health intervention for depressive symptoms? A post-hoc subgroup analysis of the CONEMO trials

Objective: To ascertain whether sociodemographic and health-related characteristics known from previous research to have a substantive impact on recovery from depression modified the effect of a digital intervention designed to improve depressive symptoms (CONEMO). Methods: The CONEMO study consisted of two randomized controlled trials, one conducted in Lima, Peru, and one in São Paulo, Brazil. As a secondary trial plan analysis, mixed logistic regression was used to explore interactions between the treatment arm and subgroups of interest defined by characteristics measured before randomization - suicidal ideation, race/color, age, gender, income, type of mobile phone, alcohol misuse, tobacco use, and diabetes/hypertension - in both trials. We estimated interaction effects between the treatment group and these subgroup factors for the secondary outcomes using linear mixed regression models. Results: Increased effects of the CONEMO intervention on the primary outcome (reduction of at least 50% in depressive symptom scores at 3-month follow-up) were observed among older and wealthier participants in the Lima trial (p = 0.030 and p = 0.001, respectively). Conclusion: There was no evidence of such differential effects in São Paulo, and no evidence of impact of any other secondary outcomes in either trial. Clinical trial registration: NCT02846662 (São Paulo, Brazil - SP), NCT03026426 (Lima, Peru - LI). Funded by the U.S. National Institute of Mental Health (grant U19MH098780).

Application of mixed reality technology in the diagnosis and treatment of oral and maxillofacial tumors / 口腔疾病防治

@#Oral and maxillofacial tumors are common oral and maxillofacial surgery-related diseases. Digital surgical technology, represented by virtual surgical design and surgical navigation, is the main auxiliary means of the surgical diagnosis and treatment of oral and maxillofacial tumors. However, the existing digital technology still has some problems and room for improvement in terms of 3D visualization imaging and intraoperative hand-eye coordination. At present, the application of 3D visualization technology represented by mixed-reality technology has been rapidly developing in the medical field. It assists in realizing the real-time stereoscopic presentation of medical images by superimposing 3D virtual images onto the real surgical environment. Mixed-reality technology has been gradually applied to the diagnosis and treatment of oral and maxillofacial tumors. Preoperatively, mixed-reality technology can be used to construct a 3D model of the tumor and its surrounding vital structures based on imaging data, at which point the medical team can personalize the preoperative assessment and design the surgical plan in the mixed-reality environment. Intraoperatively, the combination of mixed-reality technology and surgical navigation technology can be used to display the 3D virtual model in real time in the actual environment of the operation area, overcoming the hand-eye coordination problem associated with using navigation technology alone and further improving the accuracy and safety of oral and maxillofacial tumor surgery. The combination of mixed-reality technology and internet medical technology can provide a high-quality teaching platform to promote the development of regional oral and maxillofacial surgery practices. The limitations of mixed-reality technology include image occlusion, lack of accuracy when used alone, and long alignment times. In this review, the application of mixed-reality technology to the diagnosis and treatment of oral and maxillofacial tumors will be summarized and assessed by combining information from domestic and international literature reports with the practical clinical experience of the author group.

Expert consensus on digital intraoral scanning technology / 口腔疾病防治

@#Digital intraoral scanning is a hot topic in the field of oral digital technology. In recent years, digital intraoral scanning has gradually become the mainstream technology in orthodontics, prosthodontics, and implant dentistry. The precision of digital intraoral scanning and the accuracy and stitching of data collection are the keys to the success of the impression. However, the operators are less familiar with the intraoral scanning characteristics, imaging processing, operator scanning method, oral tissue specificity of the scanned object, and restoration design. Thus far, no unified standard and consensus on digital intraoral scanning technology has been achieved at home or abroad. To deal with the problems encountered in oral scanning and improve the quality of digital scanning, we collected common expert opinions and sought to expound the causes of scanning errors and countermeasures by summarizing the existing evidence. We also describe the scanning strategies under different oral impression requirements. The expert consensus is that due to various factors affecting the accuracy of digital intraoral scanning and the reproducibility of scanned images, adopting the correct scanning trajectory can shorten clinical operation time and improve scanning accuracy. The scanning trajectories mainly include the E-shaped, segmented, and S-shaped methods. When performing fixed denture restoration, it is recommended to first scan the abutment and adjacent teeth. When performing fixed denture restoration, it is recommended to scan the abutment and adjacent teeth first. Then the cavity in the abutment area is excavated. Lastly, the cavity gap was scanned after completing the abutment preparation. This method not only meets clinical needs but also achieves the most reliable accuracy. When performing full denture restoration in edentulous jaws, setting markers on the mucosal tissue at the bottom of the alveolar ridge, simultaneously capturing images of the vestibular area, using different types of scanning paths such as Z-shaped, S-shaped, buccal-palatal and palatal-buccal pathways, segmented scanning of dental arches, and other strategies can reduce scanning errors and improve image stitching and overlap. For implant restoration, when a single crown restoration is supported by implants and a small span upper structure restoration, it is recommended to first pre-scan the required dental arch. Then the cavity in the abutment area is excavated. Lastly, scanning the cavity gap after installing the implant scanning rod. When repairing a bone level implant crown, an improved indirect scanning method can be used. The scanning process includes three steps: First, the temporary restoration, adjacent teeth, and gingival tissue in the mouth are scanned; second, the entire dental arch is scanned after installing a standard scanning rod on the implant; and third, the temporary restoration outside the mouth is scanned to obtain the three-dimensional shape of the gingival contour of the implant neck, thereby increasing the stability of soft tissue scanning around the implant and improving scanning restoration. For dental implant fixed bridge repair with missing teeth, the mobility of the mucosa increases the difficulty of scanning, making it difficult for scanners to distinguish scanning rods of the same shape and size, which can easily cause image stacking errors. Higher accuracy of digital implant impressions can be achieved by changing the geometric shape of the scanning rods to change the optical curvature radius. The consensus confirms that as the range of scanned dental arches and the number of data concatenations increases, the scanning accuracy decreases accordingly, especially when performing full mouth implant restoration impressions. The difficulty of image stitching processing can easily be increased by the presence of unstable and uneven mucosal morphology inside the mouth and the lack of relatively obvious and fixed reference objects, which results in insufficient accuracy. When designing restorations of this type, it is advisable to carefully choose digital intraoral scanning methods to obtain model data. It is not recommended to use digital impressions when there are more than five missing teeth.

Comparison of the virtual surgical planning position of maxilla and condyle with the postoperative real position in patients with mandibular protrusion / 北京大学学报(医学版)

Objective:To compare the difference between virtual surgical planning(VSP)position and postoperative real position of maxilla and condyle,and to explore the degree of intraoperative realization of VSP after orthognathic surgery.Methods:In this study,36 patients with mandibular protrusion de-formity from January 2022 to December 2022 were included.All the patients had been done bilateral sagittal split ramus osteotomy(SSRO)combined with Le Fort Ⅰ osteotomy under guidance of VSP.The VSP data(T0)and 1-week postoperative CT(T1)were collected,the 3D model of postoperative CT was established and segmented into upper and lower jaws in CCMF Plan software.At the same time,accor-ding to the morphology of palatal folds,the virtual design was registered with the postoperative model,and the unclear maxillary dentition in the postoperative model was replaced.Then the postoperative model was matched with VSP model by registration of upper skull anatomy that was not affected by the opera-tion.The three-dimensional reference plane and coordinate system were established.Selecting anatomical landmarks and their connections of condyle and maxilla for the measurement,we compared the coordinate changes of marker points in three directions,and the angle changes between the line connecting the marker points and the reference plane to analyze the positional deviation and the angle deviation of the postoperative condyle and maxilla compared to VSP.Results:The postoperative real position of the maxilla deviates from the VSP by nearly 1 mm in the horizontal and vertical directions,and the anteropos-terior deviation was about 1.5 mm.In addition,most patients had a certain degree of counterclockwise rotation of the maxilla after surgery.Most of the bilateral condyle moved forward,outward and downward(the average distance deviation was 0.15 mm,1.54 mm,2.19 mm,respectively),and rotated forward,outward and upward(the average degree deviation was 4.32°,1.02°,0.86°,respectively)compared with the VSP.Conclusion:VSP can be mostly achieved by assistance of 3D printed occlusal plates,but there are certain deviations in the postoperative real position of maxilla and condyle compared with VSP,which may be related to the rotation axis of the mandible in the VSP.It is necessary to use patient personalized condylar rotation axis for VSP,and apply condylar positioning device to further improve surgical accuracy.

Consistency of gingival thickness measurement based on cone-beam CT imaging and cone-beam CT superimposed intraoral scan imaging / 中国组织工程研究

BACKGROUND:Gingival thickness is an important indicator to determine gingival phenotype.The correct evaluation of gingival phenotype is helpful for the smooth going of periodontal surgery,implant implantation and orthodontic treatment.The search for a comfortable,accurate and convenient method of measuring gingival thickness has always been a research hotspot in this field. OBJECTIVE:To analyze the gingival thickness in different dental positions and to study the consistency of cone-beam computed tomography(CBCT)image and digital intraoral scanners and cone-beam computed tomography(DIS-CBCT)superimposition image for measuring gingival thickness and determining whether the gingiva is thick or thin. METHODS:Twenty volunteers(10 males and 10 females)with complete maxillary dentition were recruited.The thickness of the gingiva 2 mm below the buccal gingival margin of 160 teeth was measured by CBCT image and DIS-CBCT digital superimposition image.Gingival thickness was used to determine whether the gingiva was thick or thin.Paired t-test was used to analyze the differences in gingival thickness measured by the two methods.Pearson correlation analysis was used to evaluate the correlation between the gingival thickness results of the two methods.The intraclass correlation coefficient(ICC)and Bland-AItman chart were used to analyze the repeatability and consistency in measuring gingival thickness using the two methods.Kappa value was used to analyze the consistency in determining whether the gingiva was thick or thin using the two methods. RESULTS AND CONCLUSION:The gingival thickness measured by CBCT image and DIS-CBCT digital superimposition image was(1.47±0.39)and(1.42±0.36)mm,respectively(t=5.673,P＜0.05).Pearson correlation analysis showed that the gingival thickness measured by the two methods was positively correlated(r=0.968,P＜0.001).In the CBCT group,the values of intraobserver and interobserver ICC were 0.980-0.982 and 0.984,respectively;in the DIS-CBCT group,the values of intraobserver and interobserver ICC were 0.941-0.984 and 0.964,respectively(P＜0.001).The intergroup ICC value of gingival thickness measured by the two methods was 0.967(P＜0.001).Bland-AItman analysis showed that 4.37%(7/160)of the points measured by both methods for gingival thickness was outside the 95%limits of agreement.There were 71 cases of thick-gingiva and 89 cases of thin-gingiva measured by CBCT imaging,and 59 cases of thick-gingiva and 101 cases of thin-gingiva measured by DIS-CBCT digital superimposition image.The Kappa value of the two groups was 0.845(P＜0.001).These findings indicate that there is a significant difference in the thickness measurement of the gingiva 2 mm below the gingival margin between the CBCT group and the DIS-CBCT group,but the correlation is very strong.The repeatability and consistency of gingival thickness measurement are both high,and there is a good consistency between the two methods when used to determine whether the gingiva is thick or thin.

Constructing an animal model of temporomandibular joint osteoarthritis in Sprague-Dawley rats by digital technology / 中国组织工程研究

BACKGROUND:Temporomandibular joint osteoarthritis is a common oral disease with a high incidence.However,temporomandibular joint osteoarthritis is not easy to be detected in the early stage,and it is difficult to obtain clinical pathological specimens,so it is difficult to carry out related research.The application of digital 3D printing technology to animal models of Temporomandibular joint osteoarthritis increases the consistency of the animal models,thus promoting the study of temporomandibular joint osteoarthritis. OBJECTIVE:To establish a standardized animal model of temporomandibular joint osteoarthritis using novel digital technology. METHODS:According to the different modeling methods of unilateral anterior crossbite,30 female Sprague-Dawley rats were randomly divided into traditional model group,digital model group,and control group(n=10 per group).Cartilage specimens of the condyles were collected at 4 and 8 weeks after modeling.The apparent morphology was observed by stereoscopic microscope.The pathological morphology was observed by hematoxylin-eosin staining and Safranin O/fast green staining.Changes in the expression of interleukin-1β and tumor necrosis factor-α were observed by ELISA,and changes in the expression of aggrecan,type Ⅱ collagen and matrix metalloproteinase-13 were observed by immunohistochemical staining. RESULTS AND CONCLUSION:Different degrees of degeneration were observed in the digital and traditional model groups.The body mass of rats in both the model groups decreased during the 1st week after intervention and subsequently demonstrated growth trend and were significantly lower than that in the control group.The results of stereoscopic microscope showed that at 4 and 8 weeks after modeling,the deformation and defect degree of the digital model group was significantly higher than that of the traditional model group.At these two time points,the Osteoarthritis Research Society International scores of the digital model group and the traditional model group were higher than those of the control group,and the Osteoarthritis Research Society International score of the digital model group was higher than that of the traditional model group(P＜0.05).Histopathological observation showed that the modified Mankin score and Osteoarthritis Research Society International score of the two model groups were significantly higher than those of the control group of the same age at 4 and 8 weeks after modeling(P＜0.05).Immunohistochemical staining results showed that at two time points,compared with the control group of the same age,the expression of aggrecan and type Ⅱ collagen decreased in the traditional model group and the digital model group,while the expression of matrix metalloproteinase 13 increased(P＜0.05).ELISA results showed that the expression levels of inflammatory factors interleukin-1β and tumor necrosis factor-α in the traditional and digital model groups were higher than those in the control group at 8 weeks,and the expression levels of interleukin-1β and tumor necrosis factor-α in the digital model group were higher than those in the traditional model group(P＜0.05).To conclude,the personalized metal tube designed and produced by 3D printing technology can quickly guide the osteoarthritis-like lesions of the temporomandibular joint without repeated trial and adjustment,which is reproducible and suitable for promotion and application.
