Prevalencia de trauma dentoalveolar en la parroquia urbana Hermano Miguel / Prevalence of dentoalveolar trauma in the Hermano Miguel urban church

Resumen Introducción: Los traumatismos dentoalveolares (TDA) son eventos que ocurren frecuentemente, llegando a comprometer órganos dentarios, sus tejidos de soporte, los maxilares y los tejidos blandos de la cara. Las estadísticas revelan cifras significativas en cuanto a la incidencia y prevalencia de estos accidentes, por lo que son considerados como un problema de salud pública global. Objetivo: Determinar la prevalencia de trauma dentoalveolar (TDA) en la parroquia urbana Hermano Miguel del cantón Cuenca- Ecuador en el año 2019. Materiales y Métodos: La investigación forma parte del proyecto "Macro estudio epidemiológico del trauma dentoalveolar en niños, adolescentes y adultos, del Cantón Cuenca, 2019" de la Universidad Católica de Cuenca. El diseño de investigación fue descriptivo/analítico y retrospectivo. Se utilizó un cuestionario validado por expertos, obteniendo información de 320 personas en 78 viviendas de entre 2 y 11 habitantes (M=4; DE=2) en 11 cuadras escogidas de forma aleatoria. Resultados: La prevalencia de trauma en la muestra fue del 8.1% (n=26); en el 28.2% (n=22) de viviendas visitadas se registraron una (23.1%) o dos (5.1%) personas con golpes en los dientes. Conclusión: El traumatismo dentoalveolar, por la frecuencia con que se presenta, se considera una urgencia odontológica de suma importancia para mantener en boca la pieza dentaria afectada y los tejidos involucrados; se considera que la arcada superior recibe más traumatismos y las causas más frecuentes suelen ser las caídas.

Abstract Introduction: Dentoalveolar trauma (DTA) are events that occur frequently, compromising dental organs, their supporting tissues, the jaws and the soft tissues of the face. Statistics reveal significant figures regarding the incidence and prevalence of these accidents, which is why they are considered a global public health problem. Objective: To determine the prevalence of Dentoalveolar Trauma (TDA) in the urban parish of Hermano Miguel in the canton of Cuenca- Ecuador in 2019. Materials and Methods: The research is part of the "Macro epidemiological study of dentoalveolar trauma in children, adolescents and adults in Cuenca Canton, 2019" of the Catholic University of Cuenca. The research design is descriptive/analytical and retrospective. A questionnaire validated by experts was used, obtaining information from 320 people in 78 dwellings of between 2 and 11 inhabitants (M=4; SD=2) from 11 randomly selected blocks. Results: The prevalence of trauma in the sample was 8.1% (n=26); in 28.2% (n=22) of the dwellings visited, one (23.1%) or two (5.1%) persons were recorded with blows to the teeth. Conclusion: Dentoalveolar trauma, due to the frequency with which it occurs, is considered a dental emergency of utmost importance to keep the affected tooth and the tissues involved in the mouth; it is considered that the upper arch received more trauma and the most frequent causes were falls.

CBCT or not CBCT: That is the Question

Root fractures comprise approximately 0.5­7% of all traumatic injuries to the permanent dentition and frequently are diagnosed after trauma to the face and mouth. Horizontal fractures are most frequent in the middle third of the root and rare in the apical third, it occurs more often in the maxillary central incisors of male patients. According to Andreasen, the healing process of horizontal root fractures depends on several variables, such as the age of the patient, the mobility of the coronal fragment, the location of the root fracture and the stage of root formation.

Association between Trauma to Primary Incisors and Crown Alterations in Permanent Successors

The aim of this study was to determine the prevalence of sequelae in permanent teeth that had their predecessors traumatized and investigate associated factors. The study was carried out with clinical and radiographic data from 137 patient charts of the Traumatized Patient Care Program, Federal University of Santa Catarina (Brazil), totalizing 253 teeth. Data were gathered on gender, age at the time of trauma, type of trauma, type of post-trauma sequelae, trauma recurrence and crown alteration in the permanent successors. No statistically significant associations were found between permanent successor's crown alteration and gender, age at the time of trauma, post-trauma sequelae or trauma recurrence (p>0.05). Significant associations were found between severe trauma (crown fracture with pulp exposure, lateral luxation, intrusion and extrusion) in the primary incisors and permanent successor's crown alteration (p<0.05). Multivariate analysis revealed an association between severe trauma to the primary incisors and permanent successor's crown alteration (OR: 4.1 - IC: 1.7-10.1). Alterations in the crown of permanent successors are associated with severe trauma to the primary incisors, as primary teeth affected by severe trauma have a fourfold greater chance of exhibiting permanent successor crown alteration in comparison to primary teeth that had minor trauma.

O objetivo deste estudo foi determinar a prevalência de sequelas nos dentes permanentes, em crianças que tiveram o seu antecessor traumatizado e os fatores associados. O estudo foi realizado com dados clínicos e radiográficos de 173 prontuários de pacientes do Programa de Assistência ao Paciente Traumatizado, Universidade Federal de Santa Catarina (Brasil), totalizando 253 dentes. Os dados coletados foram: gênero, idade no momento do trauma, tipo de trauma, tipo de sequelas pós-trauma, recorrência de trauma e alteração na coroa dos sucessores permanentes. Não houve associação estatisticamente significativa entre alteração na coroa do sucessor permanente e gênero, idade no momento do trauma, sequela pós-trauma e recorrência de trauma (p>0,05). Foram encontradas associações significativas entre trauma grave (fratura coronária com exposição pulpar, luxação lateral, intrusão e extrusão) nos incisivos decíduos e o sucessor permanente com alteração na coroa (p<0,05). A análise multivariada revelou uma associação entre trauma grave nos incisivos decíduos e alteração no sucessor permanente (OR: 4.1- IC: 1,7-10,1). Alterações na coroa dos sucessores permanentes estão associadas com trauma grave nos incisivos decíduos. Dentes decíduos acometidos por trauma grave têm quatro vezes mais chance de apresentar alteração na coroa do permanente em comparação com trauma leve.

Prevalence of dental fractures and associated factors in students of Valinhos, SP, Brazil

AIM: To investigate the prevalence of dental fractures and their association with risk factors in the permanent dentition of adolescents in Valinhos, SP, Brazil. METHODS: The study population was obtained using the probability sampling method and comprised 379 students between 13 and 19 years old enrolled in the eight State schools of the city, who were examined by nine pairs of calibrated dentists (Kappa>0.80). The presence of dental fractures in permanent anterior incisors, as well as the presence of considerable overjet (> 5mm) and lip seal was evaluated in a clinical-epidemiological examination. RESULTS: The prevalence of dental trauma was 27.1%. The most frequent lesions were enamel fractures (72.6%) of which falls were the main cause (45.7%). No association was found between the presence of considerable overjet and deficient lip seal (chi-square test; p>0.05). CONCLUSIONS: The prevalence of dental trauma in the studied population was expressive when compared with the literature, but the analyzed oral aspects did not contribute to its occurrence.
