Limas rotatorias de uso en Odontopediatría: revisión de la literatura / Rotary files for use in pediatric dentistry: Literature review

Introducción: Los dientes primarios juegan un importante papel en el crecimiento y desarrollo general de los niños, por lo que es necesario conservarlos hasta el momento de su recambio fisiológico. Cuando existe una afectación pulpar que compromete la vitalidad del diente, la pulpectomía se convierte en un reto para el odontopediatra debido a la compleja anatomía radicular de los dientes primarios. En esta revisión bibliográfica se darán a conocer diferentes sistemas de limas usados en odontopediatría, y así brindar una mirada actualizada de la instrumentación rotatoria al realizar pulpectomías en los molares primarios. Material y Método: se realizó una búsqueda bibliográfica en Pubmed y Web of Science de acuerdo con criterios de inclusión y exclusión previamente establecidos. Resultados: tras aplicar los criterios de inclusión y exclusión fueron seleccionados un total de 30 referencias bibliográficas de los últimos 15 años. Conclusión: las limas rotatorias pediátricas pueden considerarse alternativas seguras y más eficientes en la realización de pulpectomías en molares primarios, ya que se reduce el tiempo de tratamiento, se produce desbridamiento completo de los conductos y se mantiene la función del diente hasta su exfoliación.

Introduction: Primary teeth play an important role in the growth and development of children, so it is necessary to keep them until the moment of their physiological replacement. When there is a pulp involvement that compromises the vitality of the tooth, pulpectomy treatment becomes a challenge for the pediatric dentist due to the complex root anatomy of primary teeth. This review of the literature will present different file systems used in primary teeth and provide an updated look at rotary instrumentation when performing pulpectomies on primary molars. Material and Method: a bibliographic search was carried out in Pubmed and Web of Science according to previously established inclusion and exclusion criteria. Results: after applying the inclusion and exclusion criteria, a total of 30 bibliographic references from the last 15 years were selected. Conclusion: pediatric rotary files can be considered safe and more efficient alternatives in performing pulpectomies on primary molars, due to treatment time is reduced, complete debridement of the root canals is produced, and tooth function is maintained until exfoliation.

Intervención interdisciplinaria para la prevención primaria de la caries en lactantes de 0 a 18 meses / Interdisciplinary intervention for the primary prevention of dental caries in children under 18 months

Introducción: la caries es la enfermedad crónica más frecuente en la infancia. La presencia de caries en la dentición temporal es el principal factor de riesgo para desarrollar caries en la dentición definitiva. La mayoría de los factores de riesgo de la caries son modificables y pueden convertirse en elementos para la prevención y control de la enfermedad. Con el objetivo de reducir la incidencia de caries a la edad de 18 meses se diseña una intervención interdisciplinaria de prevención primaria dirigida a familias con niños que se visitan siguiendo el Protocol d’activitats preventives i de promoció de la salut a l’edat pediátrica (PAPPS). Material y métodos: ensayo clínico no aleatorizado, realizado en dos centros de asistencia primaria de Catalunya desde enero de 2019 hasta junio de 2022. En uno de los centros se diseñó e implementó una intervención educativa de prevención primaria de la caries con consejos y habilidades para las familias. En el otro centro se mantuvo el protocolo habitual de recomendaciones. Se evaluó y comparó la incidencia de caries en ambos grupos a la edad de 18 meses con un modelo de regresión logística estimado con el programa R. Resultados: la incidencia de caries a los 18 meses fue superior en los niños del grupo control (OR = 6,0; IC 95% 1,8-20,2), a pesar de que la valoración del riesgo de caries basada en el sistema llamado Caries Management by Risk Assessment (CAMBRA) indicó mayor riesgo de desarrollo de caries en los lactantes del grupo intervención. Conclusión: la intervención interdisciplinaria de prevención primaria de la caries incorporada en los programas de salud infantil reduce la incidencia de caries en los primeros años de vida. (AU)

Introduction: caries is the most common chronic disease in childhood. The presence of caries in the primary dentition is the main risk factor for developing caries in the permanent dentition. Most of the risk factors for caries are modifiable and can become elements for the prevention and control of the disease. With the goal of reducing the incidence of caries in children at age 18 months, we designed an interdisciplinary primary prevention intervention aimed at families with children who attended routine preventive visits within the PAPPS (“Protocol d’activitats preventives i de promoció de la salut a l’edat pediàtrica”) child health programme. Methodology: non-randomized clinical trial carried out in two primary care centres in Catalonia between January 2019 and June 2022. In one of the centres, an educational intervention for the primary prevention of caries was designed and implemented to provide families with guidance and skills. In the other centre, patients received standard care. The incidence of caries was assessed and compared in both groups at age 18 months by means of a logistic regression model fitted with the R software. Results: the incidence of caries at 18 months was higher in children in the control group (OR=6.0; 95% CI: 1.8-20.2), despite the fact that the caries risk assessment by means of the “Caries Management by Risk Assessment” (CAMBRA) protocol indicated a higher risk of caries in infants in the intervention group. Conclusion: the interdisciplinary primary caries prevention intervention integrated into the child health prevention and promotion programme achieved a reduction in the incidence of caries in early childhood.

Knowledge and attitudes of dental practitioners regarding the use of behaviour management techniques for paediatric dental patients.

INTRODUCTION: Understanding children's behaviour and development is crucial in managing and treating paediatric dental patients. Dental practitioners are expected to be aware of the behaviour management techniques which will facilitate routine dental treatment of the child dental patient.

Live Modeling Versus Tell-Show-Do Technique Based on Children's Heart Rates, Oxygen Saturation and Facial Image Scale.

BACKGROUND: Tell-Show-Do is most popular and Live modeling is less frequently used behavior management techniques in pediatric dentistry. This study was conducted to compare the children's response to these two techniques by measuring the objective and subjective parameters of anxiety by using pulse rate, oxygen saturation and facial-image scale. METHODS: A cross-sectional study was conducted among 138 children aged 5-10 years from December 2020 - August 2021. Children were randomly divided into three groups: Group A: Live modelling technique (mother as model), Group B: Live modelling technique (father as model), Group C: Tell-Show-Do technique. All were subjected to oral examination and rotary prophylaxis on first dental visit. Pulse oximeter was used to record heart rate, oxygen saturation along with facial-image scale scores before and after the treatment period. RESULTS: The average heart rate at the end of rotary prophylaxis session was significantly lower among children in group A than in group C (p=0.05). facial-image scale scores revealed high significance after the rotary prophylaxis treatment and it was lower in group A than group C and group B (p< 0.001). Average facial-image scale scores of fear perception by girls in group A was lower than group C and group B (p< 0.001). Oxygen saturation showed no significant differences between the three groups. CONCLUSIONS: Live modelling is equally worth practicing as Tell Show Do technique to decrease the anxiety level of children. Anxiety level increased during the procedural work than oral examination and facial image scale indicated anxiety.

An Evaluation of Knowledge, Awareness, Attitudes, and Behaviors Regarding COVID-19 Among Parents of Pediatric Dental Patients.

Children infected with COVID-19 have a critical part in community-based viral transmission. This study aimed to evaluate knowledge, awareness, attitudes, and behaviors of parents of pediatric dental patients on COVID-19 and to present required actions to prevent its spreading. A total of 524 parents took part in this cross-sectional study. A self-administered questionnaire was prepared for determining sociodemographic characteristics and socioeconomic status of parents, along with their COVID-19-related knowledge, awareness, attitudes, and behaviors. In total, 90.6% of parents were unaware that disease may show no symptoms; 61.1% and 32.6% did not know roles of "close contact with asymptomatic patients" and "dentistry practices" in transmission, respectively; 30.2% thought it could be transmitted to their children at dental clinics, and only 16.4% stated their children as carriers. Parents need to be informed on COVID-19 transmission through contact with asymptomatic individuals, risks associated with dentistry practices, and role of children in transmission.

O uso de desenhos como técnica projetiva em odontopediatria / The use of drawings as a projective technique in pediatric dentistry

The dental environment can be considered a stressor for children, and can trigger unwanted behaviors. Pediatric Dentistry is a specialty that requires professionals to know preventive measures and restorative skills to perform dental treatment in children or adolescents. In addition, it is especially important that the professional is concerned with the child's feelings and reactions, allowing the pediatric dentist to identify situations that may generate stress for the patient during the care, and manage the presented behaviors. Recent studies have measured children's reactions and feelings during dental treatments using projective techniques. Given the importance of drawing to identify children's emotions, the objective of this study was to search the literature about the use of drawings as a projective technique in Pediatric Dentistry. Therefore, projective techniques, with an emphasis on drawing, have proved to be an effective instrument to be used in clinical practice to better understand the reactions presented by children during dental care and their relationship with dentists. Thus, avoiding unexpected situations in the office and allowing greater chances of obtaining a positive return from the patient.

O ambiente odontológico pode ser considerado um estressor para o público infantil, capaz de desencadear comportamentos indesejados. A Odontopediatria é uma especialidade que exige do profissional o conhecimento de medidas preventivas e de habilidades restauradoras para a realização do tratamento odontológico na criança ou no adolescente. Além disso, é muito importante que o profissional se atente aos sentimentos e às reações da criança, e identifique situações que possam desencadear estresse para o paciente durante o atendimento odontopediátrico, e maneje os comportamentos apresentados. Estudos recentes têm mensurado as reações das crianças e seus sentimentos durante tratamentos odontológicos por meio de técnicas projetivas. Diante da importância do desenho como meio para identificar as emoções das crianças, o objetivo deste estudo foi fazer uma busca na literatura acerca do uso de desenhos como técnica projetiva em Odontopediatria. As técnicas projetivas, com ênfase no desenho, revelaram-se um instrumento eficaz a ser utilizado na prática clínica a fim de melhor compreender as reações apresentadas pelas crianças durante o atendimento odontológico e seu relacionamento com os dentistas. Elas evitam situações inesperadas no consultório e possibilitam maiores chances de se obter um retorno positivo do paciente.

Prevalence of Dental Fear among 6-15 Years Old School Children.

INTRODUCTION: Odontophobia or dental fear is a "unique phobia with special psychosomatic components that impact on the dental health of the odontophobia persons". It is well documented that dental fear has a significant impact on dental care utilization behaviors. The objective of this study was to find out the level of dental fear among school children studying in government schools of Dharan, Nepal. METHODS: A descriptive cross-sectional study was conducted from March to August 2017 among 215 school going children of Dharan of age group 6 to 15 years. Ethical approval was obtained. Children studying in six different government schools of Dharan were selected using two stage cluster sampling method. The Children's Fear Survey Schedule-Dental Subscale was used to measure dental fear among the study group. Data were entered in Microsoft Excel Sheet 2007 and analyzed in Statistical Package of Social Sciences 11.5. RESULTS: This study showed that among the total study population, 96 (44.7%) had high fear, 62 (28.8%) had moderate fear and 57 (26.5%) had low dental fear. Among males, 29 (34.5%) had high fear whereas more than half of the female respondents had high fear. CONCLUSIONS: The present study showed that most of the school going children had high fear of dental treatment. So, school health programs should be planned to make the children familiar to dentistry and proper treatment modalities should be provided to make the child comfortable to seek dental care.

The transition from amalgam to other restorative materials in the U.S. predoctoral pediatric dentistry clinics.

Increased concerns about the safety of amalgam restorations in children have resulted in many dental schools emphasizing the teaching of alternative dental materials. This study investigated the current teaching of different dental materials for use in posterior teeth in the United States predoctoral pediatric dentistry programs. In 2011, the authors invited the chairs of the predoctoral pediatric dentistry departments in all accredited dental schools at that time (N = 57) to participate in an internet-based survey. Descriptive statistics were calculated to describe the frequency of using different restorative materials. Regression models were developed to explore the factors related to the use of dental restorations in predoctoral pediatric clinics. Among the 44 dental schools that responded (77% response rate), 74% used amalgam, and 93% used composite in primary posterior teeth. Glass ionomer was used by 61% of the schools in primary posterior teeth. Placing amalgam in primary posterior teeth was associated with programs that treated more 3-5-year-old patients (ß = .302, p < .043), whereas the use of glass ionomer was associated with having students serving at off-site satellite dental clinics (ß = .015, p < .012). In general, having departments with chairs who had positive attitudes towards Minimal Invasive Dentistry (MID) used composite (ß = .091, p < .0001) and glass ionomer (ß = 103, p < .0001) more frequently and were less likely to use amalgam (ß = -.077, p < .005) in primary posterior teeth. Although teaching MID concepts in predoctoral pediatric clinics in dental schools is increasing, the use of amalgam in posterior primary and permanent teeth is still widely practiced.

Acceptance of Behavior Guidance Techniques Used in Pediatric Dentistry by Parents From Diverse Backgrounds.

Objective. To investigate if parental background affects acceptance of behavior guidance techniques. Background. Behavior guidance techniques are used for the safe and effective treatment of pediatric patients. Acceptance of these techniques may vary by racial and ethnic background. Methods. A total of 142 parents were recruited and asked to rate videos showing: active restraint/protective stabilization (AR), general anesthesia (GA), nitrous oxide sedation (N2O), oral premedication/sedation (OP), passive restraint/protective stabilization (PR), tell-show-do (TSD), and voice control (VC) techniques. Results. Hispanic parents rated VC most acceptable, followed by TSD, PR, and pharmacologic techniques. Black and white parents rated TSD, followed by N2O, as most acceptable, and AR and PR as least favorable. Hispanics found GA significantly less acceptable than whites or blacks. Hispanics were less accepting of AR than blacks; but more accepting of PR than whites. TSD was highly rated among all 3 cohorts. Parental background affected acceptance of the techniques in this study.

Dental Cone Beam Computed Tomography in Children: Clinical Effectiveness and Cancer Risk due to Radiation Exposure.

Firstly used in the early 90s to generate 3-dimensional projections of X-ray images, cone beam computed tomography (CBCT) has resulted in a large application in dentomaxillofacial imaging, even in children. CBCT uses ionizing radiation that may cause damage to the DNA, and children are at the greatest carcinogenesis risk due to their higher tissue radiosensitivity and their longer life expectancy compared to adults. The questions of whether the cancer risk is really increased after repeated dental CBCT in childhood and of what the underlying biological basis is have become hot topics in the field of dentistry and radiobiology. We performed an overview of the current literature to assess an acceptable role of CBCT in pediatric dentistry.

Does audiovisual distraction reduce dental anxiety in children under local anesthesia? A systematic review and meta-analysis.

OBJECTIVES: To perform a systematic review and meta-analysis on the effects of audiovisual distraction on reducing dental anxiety in children during dental treatment under local anesthesia. METHODS: The authors identified eligible reports published through August 2017 by searching PubMed, EMBASE, and Cochrane Central Register of Controlled Trials. Clinical trials that reported the effects of audiovisual distraction on children's physiological measures, self-reports, and behavior rating scales during dental treatment met the minimum inclusion requirements. The authors extracted data and performed a meta-analysis of appropriate articles. RESULTS: Nine eligible trials were included and qualitatively analyzed; some of these trials were also quantitatively analyzed. Among the physiological measures, heart rate or pulse rate was significantly lower (p = .01) in children subjected to audiovisual distraction during dental treatment under local anesthesia than in those who were not; a significant difference in oxygen saturation was not observed. The majority of the studies using self-reports and behavior rating scales suggested that audiovisual distraction was beneficial in reducing anxiety perception and improving children's cooperation during dental treatment. CONCLUSION: The audiovisual distraction approach effectively reduces dental anxiety among children. Therefore, we suggest the use of audiovisual distraction when children need dental treatment under local anesthesia.

Usos del láser terapéutico en Odontopediatría: Revisión de la literatura. Reporte de casos / Uses of Therapeutic Laser in Pediatric Dentistry: Review of the Literature. Case Reports

RESUMEN El término "LÁSER" es un acrónimo de "Light Amplification by the Stimulated Emission of Radiation" (en español "Amplificación de Luz por Emisión Estimulada de Radiación"). La utilización de la tecnología láser en Odontología ha tenido una constante evolución y desarrollo en los últimos 30 años. Se deben distinguir dos grandes grupos de láseres: De alta potencia o quirúrgicos y de baja potencia o terapéuticos. El más empleado en odontología pediátrica es el terapéutico o LLLT (o "blando"). El láser terapéutico está indicado para diversas anomalías tales como la hipersensibilidad, gingivitis, herpes, parestesias, neuralgias del trigémino, trismus, disfunción ATM, implantes, activación de químicos de blanqueamiento dental, entre otros. Este artículo pretende realizar una actualización de las aplicaciones del láser de baja potencia en el ámbito de la Odontología Pediátrica, así como la presentación de 4 casos clínicos representativos.

ABSTRACT The term "LASER" is an acronym for "Light Amplification by the Stimulated Emission of Radiation" (in Spanish "Amplificación de Luz por Emisión Estimulada de Radiación"). The use of laser technology in dentistry has had a constant evolution and development in the last 30 years. Two large groups of lasers should be distinguished: high-power or surgical and low-power or therapeutic. The most used in pediatric dentistry is the therapeutic or LLLT (or "soft"). The therapeutic laser is indicated for various anomalies such as hypersensitivity, gingivitis, herpes, paresthesias, trigeminal neuralgias, trismus, TMJ dysfunction, implants, activation of teeth whitening chemicals, among others. This article intends to perform an update of the applications of low power laser in the field of Pediatric Dentistry, as well as the presentation of 4 representative clinical cases.

Aplicación del Láser de Baja Potencia (LLLT) en Pacientes Pediátricos: Revisión de Literatura a Propósito de una Serie de Casos / Application of Low Power Laser (LLLT) in Pediatric Patients: Review of the Literature in a Series of Cases

RESUMEN: El uso del láser de baja potencia en odontología está siendo cada vez más frecuente y con excelentes resultados, los equipos más modernos traen pre-establecidos la dosimetría de los parámetros para las diferentes acciones clínicas. El objetivo de esta revisión fue encontrar evidencia científica que permita al clínico tener como una alternativa de tratamiento el uso del láser de baja potencia en patologías orales de tejidos blandos y duros en pacientes pediátricos. Se realizó una revisión de la literatura por medio de buscadores como PubMed, LILACS y SciELO. Después de leer a texto completo todos los trabajos es posible señalar que el láser de baja frecuencia es una buena alternativa terapéutica en la resolución de signos y síntomas en patologías orales que aquejan al paciente pediátrico, puesto que, presenta un rápido control del dolor, la inflamación, el sangrado y acelera los procesos de reparación celular.

ABSTRACT: Low Level Laser Therapy in dentistry is becoming more frequent and has had excellent results, with state of the art equipment having pre-established dosimetry parameters for the various clinical actions. The objective of this review was to find scientific evidence that allows the clinician to have the use of low power laser as treatment alternative, in oral soft tissue and hard pathologies in pediatric patients. A review of the literature was performed through search engines such as PubMed, LILACS and SciELO. After reading the texts, it was possible to point out that low frequency laser is a good therapeutic alternative in the resolution of signs and symptoms in oral pathologies of the pediatric patient. This alternative allows for rapid pain control, reduces inflammation and bleeding, and accelerates cellular repair processes.

Dental health aides in Alaska: A qualitative assessment to improve paediatric oral health in remote rural villages.

OBJECTIVE: Isolated villages in Alaska face disparities in oral health and access to care. Dental health aides such as the primary dental health aide (PDHA) and the dental health therapist (DHAT) fill a critical role for providing dental care in Alaska. Our objective was to describe strengths and barriers to paediatric dental care for children living in remote Alaska villages from the perspectives of the community and the health care system. METHODS: This qualitative study collected data through semi-structured key informant interviews with community members (n = 19) and healthcare workers (n = 19) and focus groups with patients (n = 31 adolescents and 16 caregivers of children under 12 years) living in or providing health care to 3 remote villages in Alaska. Using an inductively developed codebook and a narrative approach, 3 researchers independently read and thematically analysed the transcripts. RESULTS: Two themes emerged: (i) PDHAs and DHATs are perceived as sustainable and strongly positioned to meet the unique dental needs of the rural communities; (ii) PDHAs and DHATs face barriers that limit their effectiveness, and their distinct roles require clarification and administrative support. CONCLUSIONS: Dental health aides, both PDHAs and DHATs, are well accepted in Alaska villages. An innate understanding of cultural norms and continuity of care are key elements driving village satisfaction. The potential exists administratively to strengthen the model with the implementation of clinical and office-system strategies to increase efficiency of the dental team. Culturally adapted implementation strategies will be critical to the successful expansion of new workforce models that are addressing health disparities.

Parents' acceptance and their children's choice of pet for animal-assisted therapy (A.A.T.) in 3- to 12-year-old children in the dental operatory -A questionnaire-based pilot study.

AIM: To evaluate the parents' acceptance to therapy pets, child's most favoured pet, child's choice of soft toy as compared to live pet, and child's preference of his own pet versus therapy pet. METHODS: Sixty-two children of age groups 3-6 year, 6-9 year, and 9-12 year were selected. The data from completed questionnaires were statistically analysed and subjected to z test, Chi-squared test with P value<0.05 considered as significant. RESULTS: The consent to the presence of pet was given by 41.47% parents of 9- to 12-year-old children, 34.15% parents of 6- to 9-year-old children and 24.39% parents of 3- to 6-year-old children. Children who chose dog as their preferred pet were 56.7%; those who chose cat as their preferred pet were 44%. A majority of 3-to 6-year-olds (63.15%) had dog & cat as their choice, while 6- to 9-year-olds (65.21%) & 9- to 12-year-olds (40%) preferred dogs over all others. Dog was the favourite pet of 46.8% children. More percentage of children wanted pet provided by clinic. CONCLUSIONS: Animal-Assisted Therapy (AAT) can prove to be a good behaviour management technique if more parents are made aware and informed about AAT; dog is one of the highly recommended pets for AAT, and therapy pet should be preferred over home pet.

Paediatric oral & maxillofacial surgery.

Children have differences in their physiology, anatomy and they are continuing to grow and develop. The management of pathology, trauma, deformity and upper airway obstruction in the young growing patient has to take into account these factors in the treatment planning for these conditions. It is important for Oral & Maxillofacial Surgeons to understand the potential impact of disease or injury on the developing facial skeleton and dentition. This chapter will provide an overview of the some of the major components of paediatric maxillofacial surgery and their management.

Pediatric Dental Surgery Under General Anesthesia: Uncooperative Children.

Dental treatment of young pediatric patients can be confounded by lack of cooperation for dental rehabilitation procedures and even examination and/or radiographs. With the recent US Food and Drug Administration warning applied to many anesthetic/sedative agents for children less than 3 years old, a retrospective review of general anesthesia (GA) cases from 1 private pediatric dental practice was studied for age, gender, body mass index, anesthetic duration, airway management used, extent of dental surgical treatment, recovery time, and cardiac/pulmonary complications. For the 2016 calendar year, 351 consecutive GA cases were identified with patients aged 2-13 years. Of these, 336 underwent nasal endotracheal intubation. Forty-six of 351 patients (13%) were younger than 3 years. Median anesthesia duration was approximately 1.7 hours for all age groups. Dental treatment consisting of 8-9 teeth including crowns, fillings, and extractions was most frequently encountered. One hundred sixty-eight patients (48%), however, required care for 10-18 teeth. There were no episodes of significant oxygen desaturation. The overall complication rate was 1.1%, with 2 cases of postextubation croup, 1 case of mild intraoperative bronchospasm, and 1 case of intraoperative bradycardia. Complications did not correlate with children being overweight or obese.

The Effects of Mouth Opening and Throat Pack Placement on Uncuffed Nasal Endotracheal Tube Leakage and Delivered Tidal Volumes in Mechanically Ventilated Pediatric Patients Undergoing Dental Procedures.

Intubation for pediatric patients is frequently performed with an uncuffed endotracheal tube (ETT), which may result in an incomplete tracheal seal, resulting in gas leakage (leak). The purpose of this study was to assess the effect of (1) mouth opening and (2) throat pack placement in sealing and/or minimizing this leak to an acceptable level while providing adequate tidal volumes in mechanically ventilated patients. This prospective study of 2- to 6-year-olds undergoing general anesthesia with nasal intubation for dental procedures in the New York University-Lutheran Medical Center operating room was conducted between March 2015 and October 2015. Three sequential tidal volume (VT) measurements were recorded: postintubation with the neck extended, with mouth opened, and after throat pack placement. Twenty-five subjects were included in the analyses. For subjects in whom no leak was detected, only throat pack placement statistically improved VT. This is in marked contrast to numerically large, statistically significant effects, relative to baseline, for mouth opening (±23.2 mL, p < .009, 21% increase from baseline) and throat pack placement (±46 mL, p < .009, 41% increase from baseline) when a leak was detected. In children 2-6 years of age, nasal intubation with uncuffed ETTs that have incomplete tracheal seal have improved VT with mouth opening and throat pack placement. This finding suggests that the intubation procedure is a process that extends through positioning, mouth opening, and throat pack placement.
