Association between stress and catecholamines with painful TMD in children.

BACKGROUND: Studying biomarkers in children with temporomandibular disorders (TMD) such as epinephrine, norepinephrine, and dopamine may reveal factors like screen time or sleep loss that affect these biomarkers and predict TMD-related pain, offering new research opportunities. AIM: To determine the association between stress and catecholamines with myofascial pain and headache related to TMD in children. DESIGN: Sixty-six 9- to 11-year-old children assisting at the clinics of Pediatric Dentistry of Universidad CES participated in the study. Myofascial pain and headache attributed to TMD were determined according to the Diagnostic Criteria for TMD (DC/TMD) Axis I. Stress was evaluated with the Perceived Stress Scale-Children (PSS-C), and a 24-h urine sample was analyzed using liquid chromatography to assay catecholamines. Single and multiple regression analyses were performed. RESULTS: Children with a mean age of 10.3 years participated in the study. The mean score of stress was 29 ± 4. Perceived stress, dopamine, epinephrine, and norepinephrine were statistically significant predictors of myofascial pain and headache attributed to TMD in the single- and multiple variable logistic regression analyses. CONCLUSION: Stressful states and its biological biomarkers increase the probability of developing myofascial pain and headache attributed to TMD in children.

Tratamiento integral en odontopediatría para hipoplasia maxilar y erupción ectópica de primeros molares superiores permanentes / Tratamento integral em odontopediatria para hipoplasia maxilar e erupção ectópica de primeiros molares superiores permanentes / Integral pediatric dentistry treatment for maxillary hypoplasia and ectopic eruption of permanent upper first molars

La erupción dental ocurre cuando el diente se mueve desde su posición no funcional hasta la oclusión en la cavidad bucal. Este proceso depende de varios factores para que suceda sin alteraciones. La erupción ectópica de los primeros molares permanentes es común en la dentición mixta y requiere tratamiento inmediato por odontopediatría. Su principal causa es un maxilar hipoplásico, causando una reabsorción atípica más rápida de lo normal apresurando la exfoliación de molares primarios y llevando a una la perdida de espacio en al arco superior y el apiñamiento. Objetivo: presentar el tratamiento integral en odontopediatría para corregir la hipoplasia maxilar. Reporte de caso: Paciente asintomático de sexo femenino de 6 años asiste por primera vez a consulta odontológica en el 2019. Al examen clínico y en las ayudas diagnósticas se observa relación esquelética clase III por maxilar hipoplásico con discrepancia dentoalveolar moderada y erupción ectópica de los primeros molares superiores permanentes. Se inicia tratamiento de expansión maxilar con Hyrax y máscara facial. luego ocurre la pérdida prematura de 55 y 65, por lo que se mesializan los molares permanentes. En 2020 se instala péndulo óseo-soportado. Al año del seguimiento se observa corrección de la vía de erupción de los primeros molares permanentes. Conclusión: El tratamiento para la erupción ectópica de los primeros molares superiores permanentes debe planease de forma integral logrando objetivos en cada periodo de tratamiento para evitar complicaciones en el futuro.

A erupção dentária ocorre quando o dente se move de sua posição não funcional até a sua oclusão na cavidade bucal. Este processo depende de vários fatores para que ocorra sem alterações. A erupção ectópica dos primeiros molares permanentes é comum na dentição mista e requer tratamento imediato por um odontopediatra. A principal causa é um maxilar hipoplásico, causando uma reabsorção atípica mais rápida, acelerando a exfoliação dos molares decíduos, levando a uma perda de espaço no arco superior e ao apinhamento. Objetivo: Apresentar o tratamento integral em odontopediatria para correção da hipoplasia maxilar. Relato de caso: Paciente assintomático, sexo feminino, 6 anos, compareceu pela primeira vez a consulta odontológica em 2019. No exame clínico e nos exames diagnósticos se observou relação esquelética classe III por maxilar hipoplásico com discrepância dentoalveolar moderada, e erupção ectópica dos primeiros molares superiores permanentes. Iniciou-se o tratamento de expansão maxilar com Hyrax e máscara facial. Logo ocorreu a perda precoce do 55 e 65, devido os molares permanentes estarem mesializados. Em 2020 instalou-se o péndulo ósseo-suportado. No ano seguinte observou-se a correção da via de erupção dos primeiros molares permanentes. Conclusão: O tratamento para a erupção ectópica dos primeiros molares superiores permanentes deve-se planejar de forma integral visando atingir objetivos em cada período de tratamento para evitar complicações no futuro.

Dental eruption occurs when the tooth moves from the non-functional position to occlusion in the oral cavity. This process depends on several factors to avoid alterations. The ectopic eruption of the first permanent molars is usual in the mixed dentition and requires immediate treatment by pediatric dentistry. The main cause is a hypoplastic maxilla, causing atypical resorption, faster than normal, hastening the exfoliation of temporal molars and leading to loss space in the upper arch and crowding. Objective: Show an integral pediatric dentistry treatment to correct maxillary hypoplasia. Case report: A 6-year-old asymptomatic female patient with class III skeletal relationship, due to hypoplastic maxilla with moderate dentoalveolar discrepancy and ectopic eruption of the first permanent upper molars. She was attended by pediatric dentistry for first time in 2019 and maxillary expansion treatment began with Hyrax and facial mask. Then occur the premature loss of 55 and 65 tooth and the permanent molars moved mesially. In 2020, a bone-supported pendulum was installed. One year after following up, the correction of eruption of the first permanent molars was observed. Conclusion: The treatment for the ectopic eruption of the first permanent upper molars must be planned in an integral way, achieving objectives in each period to avoid complications in the future

Effect of removable functional appliances on mandibular length in patients with class II with retrognathism: systematic review and meta-analysis.

BACKGROUND: Orthopedic functional devices, are used to improve mandibular length in skeletal class II patients. However, the orthopedic functional device with the best effect to increasing the mandibular length, has not been identified before. Thus, the aim of the present investigation was to evaluate Randomized Controlled Trials (RCT), to determine the best functional appliance improving mandibular length in subjects with retrognathism. METHODS: A systematic review and meta-analysis was performed, including studies published and indexed in databases between 1966 and 2016. RCTs evaluating functional appliances' effects on mandibular length (Condilion-Gnation (Co-Gn) and Condilion-Pogonion (Co-Po)), were included. Reports' structure was evaluated according to 2010 CONSORT guide. The outcome measure was distance between Co-Gn and/or Co-Po after treatment. Data were analyzed with Cochran Q Test and random effects model. RESULTS: Five studies were included in the meta-analysis. The overall difference in mandibular length was 1.53 mm (Confidence Interval (CI) 95% 1.15-1.92) in comparison to non-treated group. The Sander Bite Jumping reported the greatest increase in mandibular length (3.40 mm; CI 95% 1.69-5.11), followed by Twin Block, Bionator, Harvold Activator and Frankel devices. CONCLUSIONS: All removable functional appliances, aiming to increase mandibular length, are useful. Sander Bite Jumping was observed to be the most effective device to improve the mandibular length.
