Exploring the relationship between anxiety, patient characteristics and pain outcomes in oral surgery under local anesthesia: The measurement problem.

BACKGROUND: Anxiety during oral surgery can impact patient homeostasis, increase the difficulty of the procedure and create additional stress for the surgeon. Furthermore, it has been associated with more intense and prolonged pain during and after dental treatment. OBJECTIVES: The aim of the study is to evaluate the relationship between anxiety, patient characteristics and pain outcomes in oral surgery, as well as to verify the impact of anxiety on patient's perception of pain during and after oral surgery. MATERIAL AND METHODS: This is a prospective observational study. Several variables were evaluated during the course of the oral surgery. Anxiety levels were assessed using the State-Trait Anxiety Inventory (STAI), Corah's Dental Anxiety Scale (DAS), the Interval Scale of Anxiety Response (ISAR), and Patient SelfRated Anxiety (PAnx) during the procedure. RESULTS: General anxiety measures (STAI) were not associated with specific dental anxiety or external observations of anxiety. Anxiety levels varied according to gender and body mass index (BMI), and were correlated with increased heart rate (HR) (with variability among assessment tools). Odontectomy, ostectomy and an increased volume of anesthesia were associated with higher anxiety levels (with variability among the assessment tools). There was a correlation between pain and anxiety, with anxiety contributing to approx. 12% of the variability in postoperative pain. CONCLUSIONS: Dental anxiety is a complex, multidimensional mental phenomenon characterized by high variability due to the influence of several dynamic factors.

Patient-related predictors of post-operative pain following root canal treatment: A structural model analysis.

AIM: The pathways to post-operative pain are complex and encompass factors that extend beyond the treatment protocol employed. This study aimed to identify patient-related predictors of post-operative pain following root canal treatment. METHODOLOGY: A total of 154 patients received a single-visit root canal treatment for asymptomatic necrotic mandibular molars. Before treatment, dental anxiety, dental fear and sense of coherence (SOC) were measured as predictors for each patient using validated questionnaires. Other measured predictors included gender, age, previous negative experiences at the dental offices and prior root canal treatment. Post-operative pain was assessed using the Numeric Rating Scale at multiple time-points over 30 days. Structural equation analysis was employed to evaluate the direct and indirect effects of patient-related predictors on a theoretical model of post-operative pain. The irrigant solution was also included in the model, as it was the only aspect that varied in the treatment protocol (sodium hypochlorite 2.5% and 8.25%). RESULTS: Dental anxiety (coefficient 0.028; p < .01), dental fear (coefficient 0.007; p = .02) and irrigant solution (coefficient 0.004; p = .03) exerted a direct effect on post-operative pain. SOC exerted an indirect effect on post-operative (coefficient 0.006; p = .01) through dental anxiety and dental fear. Moreover, previous negative experiences (coefficient 0.048; p = .04) exerted an indirect effect on post-operative pain through dental anxiety. CONCLUSIONS: Dental anxiety, dental fear, previous negative experiences and SOC are patient-related predictors of post-operative pain following root canal treatment. These factors should be taken into consideration in clinical practice, as patients with these characteristics may be at an increased risk of experiencing post-operative pain.

Pain, anxiety, and catastrophizing among pregnant women with dental pain, undergoing root canal treatment

Abstract This prospective study aims to evaluate dental pain, anxiety, and catastrophizing levels in pregnant women undergoing root canal treatment. Sixty pregnant and non-pregnant women presenting dental pain and an indication for root canal treatment were included in the study. Dental anxiety and catastrophizing were investigated using validated questionnaires. The endodontic intervention was performed, and a numerical scale measured preoperative and postoperative dental pain. The results were analyzed using STATA software 12.0. Unadjusted analyses assessed the association between pregnancy and pain, anxiety, and catastrophizing levels. Multiple linear regression models using 'forward stepwise' entry procedures were used to assess the independent effects of variables on pain scores. The significance level was set at 0.05. Initially, most patients experienced intense dental pain. The levels of dental pain, dental anxiety, and catastrophizing did not differ between pregnant and non-pregnant women. Logistic regression showed that postoperative pain was associated with irreversible pulpitis diagnosis (OR = 4.78; 95%CI 1.55-13.55) and high catastrophizing levels (OR = 1.96; 95%CI 1.01-3.84). Preoperative and postoperative pain rates and anxiety and catastrophizing were similar between pregnant and non-pregnant patients. Postoperative pain was associated with irreversible pulpitis diagnosis and high catastrophizing levels. The similarity between pregnant and non-pregnant women regarding preoperative and postoperative dental pain and catastrophizing and anxiety levels supports the indication of root canal treatment during the gestational period whenever necessary.

Which Dental Procedures Lead to Greater Distress During Children's Dental Treatment? A Cohort Study

ABSTRACT Objective: To assess children's self-reported distress during dental procedures and investigate risk factors. Material and Methods: A total of 163 children (3-10 years old) were included from a clinical trial on diagnostic strategies for evaluating restorations in primary teeth. Treatment plans were elaborated based on the clinical examination performed at the baseline of the study. Dentists performed 742 dental procedures, and an external evaluator collected children's self-reported distress through the Wong Backer Facial Scale (WBFS) and dentists' opinions about children's behavior during the treatment. Kruskal-Wallis Test was performed to compare the distress and the dentists' perception of the different dental procedures, and multilevel ordered logistic regression analysis was conducted to the evaluate association between explanatory variables and the outcomes. Results: More complex procedures caused more distress in children (p=0.017), with a 5.5 times higher risk than simple operative treatments. Similarly, dentists reported children's worse behavior (p<0.001). Older children (older than 7 years) reported less distress than younger children (OR 0.52; CI 0.30-0.87; p=0.014). Patients reported greater distress in the first consultations, reducing the chance of higher scores by 16% in the next interventions. Conclusion: Children experience higher levels of distress during their first treatment appointments. More complex operative procedures and the child's age below 7 years were risk factors associated with greater distress during dental treatment.

O método computadorizado de anestesia odontológica é mais efetivo que o método convencional em crianças e adolescentes? Uma revisão sistemática da literatura / Is the computerized dental anesthesia method more effective than the conventional method in children and adolescents? A systematic literature review

Objetivo:Revisar sistematicamente a literatura sobre a efetividade do método computadorizado de anestesia odontológica em relação àdor, comportamento não colaborador e o medo/ansiedade em crianças e adolescentes em comparação com o método convencional. Materiais e métodos:Uma buscaeletrônica foi realizada em cinco base de dados (Biblioteca Virtual em Saúde, Scopus, Embase, Pubmed e Web of Science)e que incluiu ensaios clínicos randomizados. A busca foi realizada em outubro de 2020 eatualizada em maio de 2021 e, não houve restrição de data ou idioma. A avaliação de risco de viés foi realizada usando aRoB 2 e, tambémfoi realizada uma análise qualitativa. Resultados:Foram encontrados 3.518 estudos, e após a remoção das duplicatas, análise do título e resumo e,leitura completa, restaram 26 estudos incluídos. Destes,cinco avaliaram ansiedade/medo, doze avaliaram o comportamento durante a anestesia, e vinte e dois avaliaram a percepção de dor. Não foi observadodiferença significativa na maioria dos estudos entreo uso do método computadorizado em comparação ao método tradicionalpara todos os desfechos analisados. Discussão:Apesar de não parecer haver diferença significativa na percepção de dor, no relato de medo/ansiedade e no comportamento entre o uso do método computadorizado emcomparação ao método tradicional, é fundamentalavaliar o comportamento da criança durante o atendimento odontológico pois suas expressões podem indicar algum desconforto e dor. Esses achados devem ser interpretados com cautela, considerando que quase três quartos dos estudos incluídos apresentaram alto risco de viés. Conclusão:Mesmo com a ausência de diferença, os dispositivos eletrônicos são promissores, visto que promovem uma administração lenta e controlada e resultam em uma anestesia segura e eficaz que coloca-se como alternativa a prática clínica.

Aim:To systematically review the literature on the effectiveness of the computerized method of dental anesthesia in relation to pain, non-collaborative behavior and fear/anxiety in children and adolescents compared to the conventional method. Materials and methods:An electronic search was performed in five databases (Virtual Health Library, Scopus, Embase, Pubmed and Web of Science)that included randomized clinicaltrials. The search was performed in October 2020 and updated in May 2021. The risk of bias assessment was performed using the RoB 2 andaqualitative analysis was also performed. Results:A total of 3,518 studieswere found, and after removing duplicates, analyzing the title and abstract, and completereading, 26 studies remainedincluded. Of these, five assessed anxiety/fear, twelve assessed behavior during anesthesia, and twenty-two assessed pain perception. No significant difference was observed in most studies between the use of the computerized method compared to the traditional method for all outcomesanalyzed. Discussion:Although there does not seem tobe a significant difference in pain perception, fear/anxiety reports and behavior between the use of the computerized method and the traditional method, it is fundamental to evaluate the child's behavior during dental care, as their expressions may indicate some discomfort and pain. These findings should be interpreted with caution, considering that nearly three-quarters of the included studies were at high risk of bias. Conclusion:Even with the absence of difference, electronic devices are promising, as they promote slow and controlled administration and result in safe and effective anesthesia, which is an alternative to clinical practice.

Effect of music during endodontic treatment on patients' anxiety: a systematic review of randomized clinical trials.

OBJECTIVES: Endodontic treatment is one of the most fearful procedures among dentistry, and the use of music during the procedure has been evaluated to control patients' anxiety. This systematic review has been conducted to provide a synthesis of the state of knowledge in this field and aimed to answer the following question: "Can music therapy reduce patient's state anxiety during endodontic treatment?". METHODS: A search was performed in six electronic databases (PubMed, Cochrane Library, Scopus, Web of Science, EMBASE, and Open Gray) for articles published until April 2022. The eligibility criteria, based on the PICOS strategy, were as follows: (P) patients undergoing endodontic treatment; (I) exposure to music; (C) no music; (O) patients' anxiety; (S) only randomized clinical trials. The risk of bias was analyzed according to the Cochrane Risk of Bias tool for randomized controlled trials (RoB 2). The strength of evidence from the included studies was assessed using the Grading of Assessment, Development, and Assessment Recommendations (GRADE) tool. RESULTS: Five eligible studies were retrieved. A low to high risk of bias was verified. Descriptive analysis showed an effect in favor of music intervention, with differences among state anxiety, heart rate and blood pressure. CONCLUSIONS: With a very low quality of evidence, dental care professionals may consider playing background music during endodontic treatment since it is a cost-effective and easy alternative to trying to reduce dental anxiety. CLINICAL RELEVANCE: Five studies were included in this systematic review and showed, with a very low quality of evidence, that music may reduce state anxiety levels on patients during root canal treatment.

The influence of anxiety on pain perception and its repercussion on endodontic treatment: a systematic review.

OBJECTIVE: To evaluate the influence of dental anxiety on the perception of pain before and during endodontic treatments. MATERIALS AND METHODS: The PRISMA checklist was followed. A search was conducted in Scopus, Medline/PubMed, The Cochrane Library, and Web of Science databases. Based on PECOS criteria, the first outcome was a possible association between pre-operative pain and anxiety. The second outcome was a possible association between intraoperative pain and anxiety. The type of studies was observational. The JBI Critical Appraisal Checklist was used to evaluate the methodological quality of articles. The certainty of the evidence was analyzed using the GRADE approach. RESULTS: Four articles were included with a total of 471 patients. Two studies found a positive association between pain and pre-endodontic treatment anxiety. Three studies investigated the relationship between anxiety and intraoperative pain; two identified an extremely significant positive association. One article noted that anxiety influences pain expectancy. The studies were of good quality as assessed by the JBI Critical Appraisal Checklist for cross-sectional studies. However, the certainty of the evidence was considered low and very low. CONCLUSIONS: Dental anxiety can be directly associated with pre- and intraoperative pain during endodontic procedures. CLINICAL RELEVANCE: It is necessary to identify patients with dental anxiety to employ therapies to bring their anxiety under control, avoiding the increase of endodontic infections, and the postponement and evasion of endodontic treatments.

Association of dental hypersensitivity and anxiety in children with molar-incisor hypomineralisation (MIH).

AIM: The objective of this study was to investigate whether dental hypersensitivity and dental fear were linked to the presence and severity of MIH. METHODS: For this cross-sectional study, 1830 students between the ages of 6 and 12 years were recruited from four randomly selected schools. The Children's Fear Survey Schedule-Dental Subscale questionnaire was used to assess dental anxiety and fear. The children's self-reported dental hypersensitivity resulting from MIH was evaluated using the Wong-Baker Facial Scale and the Visual Analog Scale (VAS). RESULTS: MIH was correlated with tooth hypersensitivity, particularly in severe cases. Dental fear was present in 17.4% of the children with MIH, but it was not associated with dental hypersensitivity, gender, or age. CONCLUSION: No association was found between dental fear and dental hypersensitivity in children with MIH.

Indicações e eficácia do tratamento restaurador atraumático / Indications and effectiveness of atraumatic restorative treatment

A fobia odontológica afeta considerável parcela da população, a ansiedade e medo frente ao tratamento dentário induzem pacientes ao cancelamento ou adiamento de tratamentos essenciais, agravando assim o seu quadro clínico. As abordagens restauradoras minimamente invasivas preconizam maior preservação dos tecidos dentários, diminuindo o desconforto e dor durante as intervenções. Sob esta ótica o Tratamento Restaurador Atraumático (ART) dispensa o uso das turbinas rotatórias, da anestesia local, do isolamento absoluto e utiliza o Cimento de Ionômero de Vidro de alta viscosidade nas restaurações. A relevância do ART no panorama odontológico e sua ampla utilização nos serviços públicos e privados de assistência bucal justificam a realização desta revisão narrativa de literatura, realizada a partir de artigos publicados nos últimos dois anos, acessados nas bases de dados online Scientific Eletronic Library On-line (SciELO), MEDLINE e LILACS. Esta pesquisa tem como objetivo reconhecer a fobia odontológica e associá-la à indicação do ART assim como definir a efetividade desta proposta de intervenção, colaborando para seu uso de forma criteriosa e adequada.

Dental phobia affects a considerable portion of the population, anxiety and fear regarding dental treatment induce patients to cancel or postpone essential treatments, thus aggravating their clinical condition. Minimally invasive restorative approaches advocate greater preservation of dental tissue, reducing discomfort and pain during interventions. From this perspective, the Atraumatic Restorative Treatment (ART) dispenses with the use of rotating turbines, local anesthesia, absolute isolation and uses high viscosity Glass Ionomer Cement in restorations. The relevance of ART in the dental panorama and its wide use in public and private oral care services justify this narrative literature review, based on articles published in the last two years, accessed in the online databases Scientific Electronic Library On- line (SciELO), MEDLINE and LILACS. This research aims to recognize dental phobia and associate it with the indication of ART, as well as to define the effectiveness of this intervention proposal, contributing to its judicious and appropriate use.

Effectiveness of a smartphone application on dental anxiety in adolescents: A randomized controlled trial.

BACKGROUND: Dental anxiety is a common issue among adolescents. Despite the use of smartphones being an important part of their daily lives, only a few digital-based interventions for dental anxiety have been tested in randomized controlled trials (RCT). AIM: The aim of this study was to evaluate a new smartphone application (App) named FALE, which was designed to demonstrate interest from the dentist to adolescent and to reduce dental anxiety. DESIGN: This is a RCT in which 184 adolescents aged 10-19 years were randomly allocated into the intervention group (IG) or the control group (CG). The intervention was applied in the waiting room before the consultation at a dental clinic. The IG answered the FALE, which contained 14 questions-of which the first and last questions addressed anxiety, whereas the CG answered the question about anxiety twice with an interval between them. RESULTS: There was a significant difference in the distribution of anxiety rating frequencies before and after the intervention period in both groups. For the IG, there was a reduction in anxiety after the intervention of 16.29%, and, in the CG, a reduction of 2.2% (p < .001). CONCLUSION: The FALE App effectively reduced dental anxiety before the appointment.

Effect of the Case for Carpule as a Visual Passive Distraction Tool on Dental Fear and Anxiety: A Pilot Study.

The present cross-over study aimed to evaluate the effect of a visual passive distraction tool, a case for carpule, in the management of fear and anxiety during invasive dental treatment. Children between the ages of 4 and 8 years that need at least two treatments with inferior alveolar nerve block were selected. All the included children received two treatments at different moments: in one treatment, local anesthesia was performed with a visual passive distraction tool, the crocodile case, for carpule (experimental); in the other treatment, local anesthesia was performed without the device (control). An evaluation of the anxiety levels was performed by measuring the heart rate and salivary cortisol levels. Wilcoxon's nonparametric test was used for a data analysis (p < 0.05). The mean heart rate with the visual passive distraction device fell from 81.8 to 78.1, while the control rose from 91.4 to 100 (p < 0.05). The mean salivary cortisol levels with the visual passive distraction device fell from 2.0 to 1.6, while in the control, they rose from 2.1 to 2.4 (p < 0.05). In conclusion, the crocodile case for carpule as a visual passive distraction device contributed positively to the management of fear and anxiety during inferior alveolar nerve block in children.

Nociception associated with pain/distress in young children sedated for dental treatment: a clinical study with objective and subjective measures.

PURPOSE: To evaluate the association between children's pain/distress levels and patient characteristics (age, sex, history of dental pain), sedation type (level of sedation, sedative regimen), nociception and pain intensity reported by the parents in sedated children undergoing minimally invasive dental treatment. METHODS: This clinical study evaluated secondary outcomes of an RCT that evaluated the efficacy of dexmedetomidine sedation with or without ketamine. Only children who had nociception levels recorded using the Analgesia Nociception Index (ANI) were included (0-100; 0 = highest nociception). FLACC scale (Face, Legs, Activity, Cry and Consolability) was used to assess children's pain/distress (0-10; 0 = no pain/distress). Parental proxy report of the child's pain intensity during the treatment was performed using the Visual Analogue Scale (VAS; 0-100; 0 = no pain). The association between ANI, children's age and sex, dental pain history, sedation level, sedative regimen, and VAS with the FLACC was verified using the generalised estimation equation analysis (alpha 0.05). RESULTS: Participants were 31 children (51.6% boys) and their parents (90.3% mothers). Median FLACC was 3.3 (25th-75th percentiles 1.7-8.2), ANI 80.9 (74.7-85.8), and VAS 10 (1-23). FLACC associated with ANI (OR 0.96; 95% CI 0.93-0.99; p = 0.02), moderate sedation (0.13; 0.03-0.50; p = 0.003), and VAS (1.05; 1.01-1.10; p = 0.01). CONCLUSION: Pain/distress was generally low and more prominent with minimal (versus moderate) sedation and higher nociception.

Relation between anxiety disorders in adolescent mothers and dental fear in children.

BACKGROUND: Maternal anxiety disorders can cause adverse consequences in child's health, cognitive development, and behavior. AIM: To investigate the association of maternal anxiety disorders with the occurrence of dental fear in children aged 24-36 months. DESIGN: This cross-sectional study is part of a cohort of adolescent mothers and their children (n = 527) in the city of Pelotas, RS, Brazil. Anxiety disorders in mothers were assessed using Mini International Neuropsychiatric Interview (DSM-IV), whereas the Dental Anxiety Question was used to assess children's dental fear. Clinical oral examinations were performed on the cohort. Poisson regression analysis was used to determine the association of maternal anxiety disorders with maternal perception of dental fear in children (p < .05). RESULTS: The prevalence of dental fear in children was 21.7% (n = 114), and maternal age, agoraphobia, social phobia, and maternal caries experience (p < .05) were associated with the presence of dental fear. After adjusted analysis, children of mothers presenting with agoraphobia (Prevalence ratios [PR] = 1.52; 95% confidence interval [CI] = 1.00-2.32) and social phobia (PR = 1.69; 95% CI = 1.06-2.71) had higher prevalence of dental fear than children whose mothers did not have any of these conditions. CONCLUSIONS: In this population of young mothers, agoraphobia and social phobia were associated with children's dental fear. Detection of and treatment for maternal mental disorders may aid in the prevention of dental fear and its oral health-related consequences.

[Anxiety level and physiological response to invasive dental treatments. a longitudinal study]. / Nivel de ansiedad y respuesta fisiológica ante tratamientos dentales invasivos. un estudio longitudinal.

Objective: To determine the relationship between the level of anxiety and the physiological response to invasive dental treatments. Materials and methods: A convenience sample of 180 patients was formed (73 men and 107 women) ≥18 years (range: 18-58) undergoing treatment with local anesthetics from three private dental offices in the city of Lima. Measurements were made before, during and after treatment on anxiety according to the IDARE questionnaire of 40 questions (20 trait and 20 state) and their physiological response was evaluated according to oxygen saturation (OS), pulse and blood pressure (BP) measured. with digital pulse oximeter and blood pressure monitor. The Friedman and Spearman correlation tests were used, working with a value of P<0.05. Results: Most patients had a medium level of anxiety before dental treatment (state 49.4% and trait 55.6%). OS, pulse and BP increased after application of the anesthetic and decreased at the end of treatment, with significant differences (P<0.05). Anxiety scores were significantly correlated only with pulse (state: r=0.238-0.564; trait: r=0.174-0.323) and BP (state: r=0.429-0.699; trait: r=0.312-0.465) (P<0.05). Conclusion: State-trait anxiety had a positive relationship with the physiological dimensions of blood pressure and pulse before dental treatment with local anesthetics.

[Virtual reality glasses as a distraction aid and anxiety reduction in a 7-year-old girl who underwent a dental extraction procedure. Case report]. / Gafas de realidad virtual como ayuda de distracción y disminución de la ansiedad en niña de 7 años que se somete a procedimiento de extracción dental. Reporte de caso.

Virtual reality in Pediatric Dentistry has enormous potential, in the treatment of phobia of dental treatments, this technology is also promising, since it shows satisfactory results and in the surgical area it has a high potential for complex treatments, allowing predictable and safe results. However, future studies should have to establish technological standards with high data quality and in the development of applications approved for clinical routine. Distraction is a non-pharmacological pain management technique commonly used by Pediatric Dentists to control pain and anxiety. There are some new techniques that use audio and video stimulation and distract the patient by exposing him to three-dimensional videos. These techniques are called virtual reality audiovisual systems. The objective of this case was to evaluate the effectiveness of virtual reality glasses as a distraction aid to reduce anxiety in a 7-year-old girl who attends the pediatric dentistry office to perform a dental extraction procedure.

Dental Fear/Anxiety in Children and Child Emotional and Behavioural Problems

ABSTRACT Objective: To investigate the association between emotional and behavioural problems and dental fear/anxiety (DFA) in children aged four to 12 years treated at a clinic in southern Brazil. Material and Methods: In this cross-sectional study where mother-child dyads were interviewed, emotional and behavioural problems were investigated using the Strengths and Difficulties Questionnaire (SDQ) (considering five subscales). Children's DFA was evaluated through the Venham Picture Test. For each SDQ subscale, Poisson regression model was explored. Prevalence ratios (PR) were estimated, considering a significant level of p ≤ 0.05. Results: Overall, 128 children participated in this study. Most children were female (54.7%) and aged between 7 and 9 years (39.8%). The prevalence of emotional problems was 47.7% and behavioural problems were 46.1%. The prevalence of DFA was 18.8%. Children with emotional problems had a 2.3 higher prevalence of DFA (95%CI 1.06-5.04). In general, behavioural problems were not associated with DFA (95%CI 0.84-3.34) only when conduct problems were considered (2.20; 95%CI 1.02-4.70). Conclusion: Children aged between 4 and 12 years who present emotional and conduct problems tend to show higher DFA.

Do patients with molar incisor hypomineralization have more dental anxiety and behavior management problems? A systematic review with meta-analysis

Abstract This systematic review evaluated the available evidence on whether children with molar incisor hypomineralization (MIH) have more dental fear and anxiety (DFA) and dental behavior management problems (DBMPs) than those without MIH (Prospero CDR42020203851). Unrestricted searches were performed in PubMed, Scopus, Web of Science, Lilacs, BBO, Embase, Cochrane Library, APA PsycINFO, Open Grey, and Google Scholar. Observational studies evaluating DFA and/or DBMPs in patients with and without MIH were eligible. Reviews, case reports, interventional studies, and those based on questionnaires to dentists were excluded. The methodological quality assessment was based on the Newcastle-Ottawa Scale. Random-effects meta-analyses were conducted to synthesize data on DFA. The certainty of evidence was performed according to GRADE. Seven studies that evaluated a total of 3,805 patients were included. All of them presented methodological issues, mainly in the comparability domain. Most studies observed no significant difference in DFA between children with and without MIH. The meta-analysis did not show a significant effect of MIH on the standardized units for the DFA scores (SMD = 0.03; 95%CI: -0.06-0.12; p = 0.53; I2 = 0%). Synthesis including only the results for severe cases of MIH also did not show a significant effect of the condition on DFA scores (MD = 8.68; 95%CI: -8.64-26.00; p = 0.33; I2 = 93%). Two articles found DBMPs were significantly more frequent in patients with MIH. The overall certainty of evidence was very low for both outcomes assessed. The current evidence suggests no difference in DFA between children with and without MIH; DBMPs are more common in patients with MIH. This information should be viewed with caution because of the very low quality evidence obtained.

Técnicas no-farmacológicas en el manejo del comportamiento ante el tratamiento odontológico del niño

Introducción: Muchas veces la experiencia del niño encuentra la manera de responder ante un problema de una forma más verosímil, siendo más real que se concentre la atención en la clínica del niño. Objetivo: Determinar la efectividad de esas técnicas en el control de la ansiedad en niños ante el tratamiento estomatológico. Métodos: La investigación fue de carácter experimental y cuantitativo, se tomó una población muestral de 16 niños de 6-11 años de edad. Los cuales fueron hechos para la intervención con técnicas no farmacológicas. Resultados: Después de realizado en análisis, se utilizó la prueba t de Student, que constituyó el 56,25 % de los niños del grupo experimental y el 50 % del grupo control se encontraron en el rango de edad de 8-9 años, 31,25 % y 37,5 % entre 6-7 años y el 12,50 % en ambos grupos de 10-11 años respectivamente; a diferencia del grupo control que el 75 % de los niños, presentaban alta ansiedad, y el 68,75 % estaban en una ansiedad moderada. Conclusiones: Las técnicas no farmacológicas son efectivas en el manejo de los comportamientos en la consulta odontológica, a diferencia en niños del grupo control sin esta intervención disminuyen a nivel moderado.

Introduction: Many times the experience of the child finds a way to respond to a problem in a more credible way, being more real than the attention of the child's clinic is combined. Objective: To determine the effectiveness of these techniques in the control of anxiety in children before dental treatment. Methods: It was an experimental and quantitative subject; a sample population of 16 children from 6 to 11 years of age was taken. Which were made for intervention with non-pharmacological techniques. Results: After the analysis, the t-Student test was used, which is 56.25 % of the children of the experimental group and 50 % of the control group are in the age range of 8 to 9 years, 31.25% and 37.5% between 6 to 7 years and 12.50 % in both groups from 10 to 11 years respectively; unlike the control group, 75 % of the children before the care presented high anxiety, after which 68.75 % presented moderate anxiety. Conclusions: Non-pharmacological techniques are effective in managing behaviors in the dental office, unlike children in the control group without this intervention, they decrease to a moderate level.
