Abstract This study analyzes the characteristics of the top 100 most-cited papers related to tooth bleaching. A literature search was performed on the Web of Science up to March 2022. The number of citations was cross-matched with the citation count on Scopus and Google Scholar. The following data were collected: number and density of citations; authorship; year and journal of publication; study design and thematic; keywords; institution and country of origin. Spearman’s correlation and Poisson regression were used to determine associations between the number of citations and study characteristics. The VOSviewer software was used to generate collaborative network maps for the authors and keywords. The number of citations ranged from 66 to 450. Papers were published between 1981 and 2020. The most frequent study design and topic were laboratory-based studies and ‘interaction of the bleaching agent with dental tissues’, respectively. Cochran M, Loguercio AD, Matis B, Reis A, and Suliman M were the authors with the highest number of papers. The countries with the most papers were the United States of America (USA) (28%) and Brazil (20%). Indiana University and State University of Ponta Grossa were the institutions with the most papers (6% each). There was a very strong correlation among the number of citations of the three databases. The 100 most-cited papers related to tooth bleaching were mainly published by the USA and Brazil, with laboratory-based studies addressing topics related to the effects of bleaching agents on tooth structure being the most prevalent.

Houve uma correlação muito forte entre o número de citações das três bases de dados. Os 100 artigos mais citados relacionados ao clareamento dentário foram publicados principalmente pelos EUA e Brasil, sendo os estudos laboratoriais que abordaram tópicos relacionados aos efeitos dos agentes clareadores na estrutura dentária os mais prevalentes.

RESUMO Objetivo: Revisar a literatura sobre as percepções de crianças e seus pais a respeito de trajes médicos. Fontes de dados: Buscas sistemáticas foram conduzidas nas bases de dados EMBASE, Literatura Latino-americana e do Caribe em Ciências da Saúde (LILACS), PubMed, PsycINFO, Scopus e Web of Science. A literatura cinzenta foi pesquisada no Google Scholar, Open Grey e ProQuest Dissertations e Theses Database. Síntese dos dados: Foram identificadas 2.567 publicações e, após uma seleção de duas fases, foram incluídos 15 estudos na síntese qualitativa. As crianças tinham preferência pelo uso de jaleco branco em cinco dos nove estudos incluídos (55,5% [IC95% 48,3-62,7]; p=1,00). Em 11 dos 15 estudos incluídos, os pais tinham preferência pelos médicos que utilizavam jaleco (73,3% [IC95% 67,9-78,6]; p=0,11). Conclusões: Com uma qualidade baixa de evidência, crianças e pais preferem os médicos que usam jaleco branco.

ABSTRACT Objective: To review the literature about children’s and parent’s perceptions on surgical attire. Data source: A systematic search was conducted in the databases EMBASE, Latin American and Caribbean Health Sciences (LILACS), PubMed, PsycINFO, Scopus and Web of Science. Grey literature was searched on Google Scholar, Open Grey and ProQuest Dissertations, and Theses Database. Data synthesis: A total of 2,567 papers were identified. After a two-phase selection, 15 studies were included in narrative synthesis. Children favored wearing white coats in five of the nine included studies (55.5% [95%CI 48.3-62.7]; p=1.00). With respect to parents’ preferences, results of vote counting showed that in 11 of 15 included studies, they favored physicians wearing white coats (73.3% [95%CI 67.9-78.6]; p=0.11). Conclusions: Children and parents have preferred physicians to wear a white coat with a very low certainty of evidence.

Abstract: The purpose of this review was to identify and analyze the main characteristics of the 100 most-cited papers in the field of endodontic therapy in primary teeth. A search for the most-cited articles was conducted in the Clarivate Analytics Web of Science ‘Core-Collection’ (WoS-CC) database up to December 2020. Papers were ranked in descending order, by number of citations, and each paper was matched with the citation count on Scopus and Google Scholar. Two independent reviewers selected the most-cited papers and analyzed it according to the number and density of citations, year and journal of publication, authors, countries and contributing institutions, study design, topic of the paper, and keywords. Spearman’s correlation and Poisson regression were used to determine associations between the number of citations and study characteristics. The citation count varied from 15 to 135 (WoS-CC), 8 to 141 (Scopus), and 14 to 317 (Google Scholar). Of the 306 contributing authors, most paper contributions were from Sakai VT, Oliveira TM, and Machado MAAM (5 each). Most of the papers originated from the USA (n=21) and Brazil (n=18). Randomized trials were the most common study design (n=32), and “pulpotomy” was the most frequently used keyword (n=35). Poisson regression showed that the number of citations decreased by 1.5% each year, and increased by 9.7% for each unit of impact factor. This bibliometric analysis highlighted papers, authors, and institutions that have contributed to endodontic therapy in primary teeth. Common terms of interest in this research area was also identified, representing the first bibliometric analysis on this subject.

Abstract Efficient working length determination is essential for a successful endodontic treatment. The purpose of the present study was to evaluate whether the method for determining the working length of root canals (radiographic or electronic) influences the obturation level of primary molars. Thus, a controlled, triple-blind, randomized clinical trial was conducted. Sixty-four children aged 6 to 9 years with an indication for primary molar pulpectomy were included. Participants were divided into two groups according to the method used to determine the working length of the root canals: (G1) radiographic and (G2) using an electronic apex locator. The study had 3 operators: #1 performed the clinical procedures, except the electronic measurement; #2 performed radiographic measurement and final evaluation of obturation level; and #3 performed eligibility criteria and electronic measurement. Adequacy of obturation level was evaluated based on the final conventional radiography and it was recorded as acceptable or unacceptable (short or overfilled). Data were analyzed with repeated measures logistic regression. There was no difference between the obturation level of primary molars measured by radiographic and electronic methods (p > 0.05). The other investigated variables (age, tooth type, dental arch position, last instrumentation file, and canal location) also did not influence the obturation level (p > 0.05). In conclusion, both measurement methods resulted in similar adequacy of obturation level in primary molars after pulpectomy.

Abstract This study aimed to answer the following question: What is the proportion of acceptance reported by parents toward pediatric behavior guidance techniques (BGTs)? Observational studies that evaluated parental acceptance of BGTs during pediatric dental visits among parents of non-special health care need (non-SHCN) and SHCN children were included. A search of the Cochrane Library, Latin American and Caribbean Health Sciences (LILACS), MedLine/PubMed, PsycINFO, Scopus, and Web of Science databases, in addition to gray literature, was performed until October 2021. The Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies was used for quality assessment. The certainty of evidence was assessed using the Recommendation, Assessment, Development, and Evaluation (Grade). Fifty-three studies with 4868 participants were included, and 42 were retained for the random-effects proportion meta-analysis. The methodological quality varied from low to high. The agreement with the BGTs varied from 85.6% (95%CI: 77.5–92.1; p < 0.001; I 2 = 93.6%; 16 studies; n = 1399) for tell-show-do to 25.7% (95%CI: 17.8–34.4; p < 0.001; I 2 = 90.4%; 12 studies; n = 1129) for passive protective stabilization among non-SHCN children’s parents; meanwhile, among the parents of SHCN children, it varied from 89.1% (95%CI: 56.1–99.7; p < 0.001; I 2 = 95.7%; 3 studies; n = 454) for tell-show-do to 29.1% (95%CI: 11.8–50.0; p = 0.001; I 2 = 84.8%; 3 studies; n = 263) for general anesthesia. The effect estimates varied greatly, as substantial heterogeneity across studies was observed, thus limiting the confidence in the results. Parents were more likely to agree with basic BGTs over advanced BGTs, with very low certainty of evidence. Dentists should discuss BGT options with parents. Protocol registration: PROSPERO CRD42018103834.

RESUMO Objetivo: Investigar a prevalência de problemas para dormir por motivos dentários autorrelatado e sua associação com condições orais adversas em escolares. Métodos: Estudo transversal com amostra representativa de 1589 escolares de 8 a 10 anos matriculados em escolas públicas de Florianópolis, Brasil. Os dados não clínicos incluíram um questionário sobre indicadores socioeconômicos respondidos pelos pais/cuidadores. As crianças foram questionadas se tinham problemas para dormir por motivos dentários e sobre episódios anteriores de dor de dente. Foram realizados exames clínicos orais para avaliar: cárie dentária - Índice de Dentes Cariados, Perdidos e Obturados (índice CPO-D/ceo-d) - e suas consequências clínicas (índice PUFA/pufa - presença de envolvimento pulpar (P/p); ulceração (U/u); fístula (F/f); e abscessos (A/a) e traumatismo dental (TD). Foram realizados análise descritiva e modelos ajustados de regressão logística (p<0,05; IC95%). Resultados: A prevalência de problemas para dormir por motivos dentários foi de 28%. Crianças com cárie dentária não tratada (OR 1,32; IC95% 1,05-1,67) e presença de índice PUFA/pufa (OR 1,89; IC95% 1,45-2,46) apresentaram maiores chances de relatar problemas para dormir devido a razões dentárias. Conclusões: Aproximadamente, um terço das crianças apresentou problemas para dormir devido a razões dentárias. Cárie dentária não tratada e suas consequências clínicas foram associadas a problemas autorrelatados para dormir por motivos dentários em escolares.

ABSTRACT Objective: To investigate the prevalence of self-reported trouble sleeping due to dental problems and its association with oral conditions in schoolchildren. Methods: This is a cross-sectional study carried out with a representative sample of 1,589 schoolchildren aged 8-10 years enrolled in public schools from Florianópolis, Santa Catarina, Brazil. Non-clinical data included a questionnaire about socioeconomic indicators answered by parents/guardians. Children were questioned about whether they had trouble sleeping due to dental problems and about previous history of toothache. Clinical oral examinations were performed to evaluate dental caries - Decayed, Missing, and Filled Teeth Index (DMFT/dmft index) and its clinical consequences [PUFA/pufa index: considering the presence of pulpal involvement (P/p); ulceration of tissues due to tooth fragments from decayed crowns (U/u); fistula (F/f); and abscesses (A/a), and traumatic dental injuries (TDI)]. We conducted a descriptive analysis and used adjusted logistic regression models (p<0.05; 95%CI). Results: The prevalence of trouble sleeping due to dental problems was 28%. Children with untreated dental caries (OR 1.32; 95%CI 1.05-1.67) and clinical consequences from the PUFA/pufa index (OR 1.89; 95%CI 1.45-2.46) had higher chances of reporting trouble sleeping due to dental problems. Conclusions: Approximately one-third of the children declared having trouble sleeping due to dental problems. Untreated dental caries and its clinical consequences were associated with self-reported trouble sleeping due to dental problems in schoolchildren.

RESUMO Objetivo: Determinar a associação entre a percepção dos cuidadores sobre a saúde bucal das crianças e características sociodemográficas, relato de dor dentária e condições clínicas bucais. Métodos: Foi realizado um estudo transversal com 570 crianças de dois a cinco anos matriculadas em pré-escolas públicas e seus cuidadores. Os dados referentes à percepção do estado de saúde bucal nas crianças, características sociodemográficas e dor dentária foram coletados por meio de um questionário. Três examinadores (Kappa>0,7) avaliaram o estado de saúde bucal das crianças usando o índice ceo-d, o índice PUFA e a classificação de Andreasen para traumatismo dentário (TD). A ocorrência de mordida aberta e overjet também foi investigada. Análise descritiva e regressão logística não ajustada e ajustada foram realizadas, considerando um nível de significância de 5%. Resultados: A percepção da má condição de saúde bucal nas crianças foi de 24,7%, a qual aumentou 4,92 vezes (IC95% 3,05-7,93) quando as crianças apresentaram cárie dentária e 3,78 vezes (intervalo de confiança de 95% [IC95%] 1,63-8,76) quando houve consequências de cárie dentária. A percepção de saúde bucal ruim também foi associada a mordida aberta (Odds Ratio [OR] 1,98; IC95% 1,16-3,38) e TD (OR 1,68; IC95% 1,06-2,68). Não foram encontradas associações entre as percepções dos cuidadores e variáveis sociodemográficas ou overjet. Conclusões: As percepções dos cuidadores sobre a má condição de saúde bucal das crianças foram associadas à cárie dentária, suas consequências, TD e mordida aberta.

ABSTRACT Objective: To determine the association between the perception of caregivers regarding the oral health of their children and socio-demographic characteristics, report of dental pain, and clinical oral conditions. Methods: A cross-sectional study was conducted with 570 children aged two to five years old, enrolled at public preschools, and with their caregivers. Data regarding perceptions of oral health status in children, socio-demographic characteristics, and dental pain were collected from a questionnaire. Three examiners (Kappa>0.7) evaluated children’s oral health status using the dmft index, pufa index, and the Andreasen classification for traumatic dental injury (TDI). The occurrence of open bite and overjet was also investigated. Descriptive analyses, and unadjusted and adjusted logistic regression were used, considering a 5% significance level. Results: A total of 24.7% of children had poor oral health status, which increased 4.92-fold (95% confidence interval [95%CI] 3.05-7.93) when children had dental caries, and 3.78-fold (95%CI 1.63-8.76) when there were consequences from dental caries. The perception of poor oral health was also associated to open bite (Odds Ratio [OR] 1.98; 95%CI 1.16-3.38) and TDI (OR 1.68; 95%CI 1.06-2.68). No associations were found between the perception of caregivers and socio-demographic variables or overjet. Conclusions: The perception of caregivers of poor oral health in their children was associated to dental caries, its consequences, TDI, and open bite.

RESUMO Objetivos: Este trabalho avaliou a percepção dos responsáveis sobre a ansiedade odontológica das crianças e sua associação com as variáveis independentes: ansiedade odontológica dos responsáveis e o motivo para sua última consulta odontológica, fatores socioeconômicos, última visita ao dentista dos responsáveis e da criança, condição bucal da criança e tipo de procedimento odontológico realizado na consulta. Métodos: Neste estudo transversal a amostra contou com 58 crianças entre 6 e 9 anos e seus responsáveis. Os participantes foram selecionados a partir de um estudo clínico em que metade das crianças receberam fluorterapia e as outras exodontia. Os responsáveis responderam ao questionário socioeconômico e para avaliar a ansiedade odontológica e a percepção sobre a ansiedade odontológica das crianças eles responderam a Dental Anxiety Scale e a Dental Anxiety Question, respectivamente. Para avaliar a ansiedade odontológica das crianças foi aplicado o Venham Picture Test Modificado e a sua condição bucal foi verificada pelo índice CPO-D/ceo-d. A análise dos dados foi realizada pelo teste Qui-quadrado, Exato de Fisher e Mann-Whitney. Resultados: A frequência de responsáveis que perceberam a ansiedade odontológica das crianças foi de 50,9%. Entretanto, 41,4% das crianças relataram a ansiedade odontológica. Houve uma diferença significativa entre o Dental Anxiety Question e o Venham Picture Test Modificado (p = 0,002). Não houve relação entre a percepção dos responsáveis sobre a ansiedade odontológica das crianças com as demais variáveis independentes. Conclusão: Existiu uma diferença significativa entre a ansiedade odontológica das crianças e a percepção desta pelos responsáveis.

ABSTRACT Objectives: This research evaluated the caregivers’ perception on dental anxiety of their children and verified its association with independent variables: caregivers’ dental anxiety and the reason for their last dental appointment, socioeconomic factors, caregivers and children’s last dental visit, children’s oral health status, dental anxiety and kind of dental appointment. Methods: Fifty-eight children aged 6 to 9 years old and their caregivers participated in the study. For this cross-sectional study the participants were selected from a clinical study where half of the children received fluortherapy and the other half tooth extraction. The caregivers answered questions about socioeconomic status and to evaluate their dental anxiety and the perception on children’s dental anxiety they answered the Dental Anxiety Scale and Dental Anxiety Question, respectively. To evaluate children’s dental anxiety the Modified Venham Picture Test was applied and their oral health status was verified with the DMFT index. Data were analyzed with Chi-square, Fisher’s Exact and Mann-Whitney’s test. Results: The frequency of the caregivers’ perception on dental anxiety of their children were 50.9%. However, 41.4% of children reported dental anxiety. There was a significant difference between Dental Anxiety Question and Modified Venham Picture Test (p=0.002). There was no relationship between caregivers’ perception on dental anxiety of their children and other independent variables. Conclusion: There was a significant difference between children’s dental anxiety and the perception of it by those caregivers.

Abstract The present study aimed to identify the scientific evidence regarding the association between crown discoloration and pulp necrosis in traumatized permanent teeth. A systematic literature search was conducted in the PubMed/Medline, Lilacs/BBO, Scopus, Web of Science, Cochrane Library databases, and grey literature. Quality assessment and bias control were carried out according to the Fowkes and Fulton guidelines. Meta-analysis was performed, and the odds ratio was calculated with a 95% confidence interval. The quality assessment of the evidence was determined for the meta-analysis outcomes using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. From 2,702 studies identified, five articles met the inclusion criteria. One among these showed no methodological soundness and was excluded from the meta-analysis, and the remaining four studies were included in the meta-analysis. The total number of traumatized permanent teeth evaluated in the meta-analysis was 367. The results showed a positive association between crown discoloration and pulp necrosis in permanent teeth. Teeth with crown discoloration showed 23 times more chance to present pulp necrosis than teeth without crown discoloration (OR 23.82 [1.25, 452.87]; p = 0.03), with a very low certainty of evidence. There is a significant association between crown discoloration and pulp necrosis of traumatized permanent teeth. Due to the very low strength of evidence according to GRADE, this result should be viewed with caution.

Abstract The aim of this study was to verify the oral habits, symptoms, and characteristics of some children aged 8 to 10 years that could be associated with possible sleep bruxism. A cross-sectional study was performed. Questionnaires were sent to parents to obtain information on sex, age, school shift, sleep quality, parents’ perception of children’s behavior, and children’s oral habits (nail biting, object biting, and lip biting), and symptoms such as headache or earache. In addition, parents reported the frequency of sleep bruxism (no day to 7 days a week). Descriptive analysis and multinomial logistic regression were performed and the level of significance was set at 5%. A total of 1,554 parents of children aged 8 to 10 years participated in this study. Possible sleep bruxism was reported as mild for 65.7%, moderate for 25.3%, and severe for 9% of the children. In the adjusted multinomial logistic regression, boys were 79% more likely to have sleep bruxism (OR: 1.79; 95%CI 1.23–2.60) and were 2.06 more times at risk of being in the habit of lip biting (OR: 2.06; 95%CI 1.26–3.37). Children with possible severe sleep bruxism were 61% more likely to develop object biting (OR: 1.61; 95%CI 1.09–2.39), 52% more likely to have headaches (OR: 1.52; 95%CI 1.01–2.28), and 3.29 more times at risk of poor sleep quality (OR: 3.29; 95%CI 2.25–4.82). Based on the report, boys with lip and object biting habits, headaches, and poor sleep quality presented a higher chance of possible severe sleep bruxism.

Abstract Objective: To analyze whether demographic and socioeconomic factors can influence the OHRQoL in schoolchildren. Material and Methods: A cross-sectional study using a representative sample of 1137 children aged 8-10 years, enrolled in public schools in Florianópolis, Brazil, was conducted. Children answered the Brazilian version of the Child Perceptions Questionnaire (CPQ8-10) quality of life questionnaire and their parents responded to socioeconomic and demographic questions. Logistic regression models were used to analyze the data. Results: Higher probability of presenting a negative impact on the OHRQoL was observed in children whose skin color was non-white (OR 1.46, 95% CI 1.04-1.69) and female (OR 1.33, 95% CI 1.04-1.69). Children in whom the head of the family had years of schooling 9-11 (p=0.001), 5-8 (p=0.005) and ≤4 (p=0.000) were more likely to have a negative impact on the OHRQoL. CPQ8-10 domains evaluation showed that variables education, gender, skin color, and age were associated with a negative impact on OHRQoL (p≤0.05). Conclusion: The educational level of the head of the family and the demographic characteristics of the children are associated with a negative impact on the OHRQoL.

RESUMO Objetivo: Avaliar o impacto do trauma dental (TD) e do comprometimento estético na qualidade de vida (QV) de pré-escolares e familiares. Métodos: Este estudo foi realizado com crianças de 2 a 5 anos em 11 pré-escolas de Florianópolis (SC), Brasil. Os pais/responsáveis preencheram a versão brasileira do questionário sobre QV Early Childhood Oral Health Impact Scales (B-ECOHIS), um questionário socioeconômico e perguntas específicas sobre TD. As crianças foram examinadas por três examinadores calibrados (kappa>0,7). O TD foi avaliado de acordo com os índices adotados pela Organização Mundial de Saúde (OMS), e o comprometimento estético também foi classificado. Os dados foram analisados descritivamente e submetidos à análise bivariada por qui-quadrado e teste de Fisher, sendo significante p<0,05. Resultados: Dos pré-escolares examinados, 62,5% foram diagnosticados com trauma e 15,6% com comprometimento estético, e somente 12% dos pais relatou que seus filhos apresentam impacto na QV. O TD não se associou a sexo, idade ou QV. A alteração de cor da coroa por TD relacionou-se ao comprometimento estético, e apenas este causou impacto negativo na QV (p<0,05) e se associou ao domínio limitações orais (p<0,05). Conclusões: O comprometimento estético causou impacto negativo na QV das crianças, e o trauma dental não se associou com a QV das crianças nem de suas famílias.

ABSTRACT Objective: To evaluate the impact of dental trauma and impaired esthetics on the quality of life (QoL) of preschool children and their relatives. Methods: Study conducted with 192 children aged 2 to 5 years in 11 preschools in Florianópolis, Santa Catarina, South of Brazil. Parents/caregivers completed a questionnaire on quality of life (Brazilian version of the Early Childhood Oral Health Impact Scales - B-ECOHIS), a socioeconomic survey, and then answered specific questions related to dental trauma. The subjects were examined by three accordant examiners (Kappa>0.7). Dental trauma was evaluated on the basis of indexes adopted by the World Health Organization, and esthetic impairment was then classified. Data were descriptively analyzed and put to bivariate analysis by chi-square and Fisher tests, with significance level at 5%. Results: The prevalence of dental trauma was 62.5% with 15.6% of esthetic impairment. Almost 12% of parents reported impact on the quality of life of their children. Dental trauma was not significantly associated with gender, age or QoL. Crown color change by trauma was associated with esthetic impairment. Also esthetic impairment had a negative impact on QoL (p<0.05) and was associated with oral limitations (p<0.05). Conclusions: Esthetic impairment had a negative impact on children’s quality of life, while dental trauma was not associated to it.

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.

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.
