Objective:To investigate the efficacy of pulp revascularization in the treatment of pulp necrosis with periapical periodontitis in young permanent teeth and its effect on the levels of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in gingival crevicular fluid.Methods:From January 2021 to August 2021, 72 young patients with permanent teeth exhibiting pulp necrosis and apical periodontitis who were treated at Haiyang People's Hospital were included in this study. These patients were subsequently divided into a study group ( n = 35) and a control group ( n = 37), depending on their respective treatment methods. The control group underwent conventional apical angioplasty, whereas the study group underwent pulp revascularization. A comparative analysis was conducted to assess the clinical efficacy of both treatments. Additionally, levels of VEGF and bFGF in gingival crevicular fluid were measured before and after surgery, and these values were compared between the two groups. Relevant clinical indicators and the incidence of adverse reactions were also compared between the study and control groups. Results:The overall response rate in the study group was 94.3% (33/35), which was significantly higher than 70.3% (26/37) in the control group ( χ2 = 7.01, P < 0.05). Prior to surgery, there were no notable differences in VEGF level, bFGF level, root length, or root canal thickness between the two groups (all P > 0.05). However, after surgery, VEGF level, bFGF level, root length, and root canal thickness in the study group were (43.25 ± 4.87) ng/L, (40.72 ± 4.83) ng/L, (8.95 ± 0.27) mm, and (3.08 ± 0.24) mm, respectively. These values were (39.90 ± 4.80) ng/L, (36.05 ± 4.66) ng/L, (8.55 ± 0.18) mm, and (2.90 ± 0.20) mm, respectively, in the control group. There were significant differences in VEGF level, bFGF level, root length, and root canal thickness between the two groups ( t = 2.96, 4.18, 5.67, 2.88, all P < 0.05). After surgery, the scores for apical inflammation, root development, and Visual Analogue Scale (VAS) in the study group were significantly higher than those in the control group ( t = 7.61, 4.83, 9.47, all P < 0.001). The incidence of adverse reactions in the study group was 2.9% (1/35), which was significantly lower than 21.6% (8/37) in the control group ( χ2 = 5.79, P < 0.05). Conclusion:Pulp revascularization exhibits superior curative effects compared with conventional apical angioplasty for the treatment of pulp necrosis and apical periodontitis in young permanent teeth. This treatment effectively alleviates pain, markedly improves tooth function, and has a low incidence of adverse reactions, highlighting its clinical value as a therapeutic option.

ABSTRACT Objective: To perform a bibliometric analysis on deciduous and permanent eruption publications to discuss the global trends and prospects on the topic. Material and Methods: A systematic search was conducted on the Scopus database. The characteristics of the publications, including co-cited authors, organizations, countries, most cited sources, publications, and keyword co-occurrence, were analyzed using VOSviewer software version 1.6.18. Results: After applying exclusion criteria, 492 studies were included in the analysis. The majority of research centers were located in Europe. "Archives of Oral Biology" emerged as the most frequently cited journal. The United States and Brazil were the most frequently cited countries in the publications. Notable co-authors included Kuchler E. C. and Hägg U. The most frequently cited keywords were associated with oral pathologies, tooth development, odontogenesis, and genetics. The most recent papers were published in journals focused on oral diseases. Conclusion: This bibliometric analysis highlights that the future of research in this field is likely to be focused on the investigation of tooth eruption in both deciduous and permanent teeth, with an emphasis on genetics, tooth development, timing of tooth eruption, and syndromic conditions. While well-accepted in the fields of Pediatrics and Orthodontics, there is a growing interest in this topic within oral biology and pathology journals in the Americas, with the United States and Brazil leading in terms of publications and citations.

Abstract Objective: To evaluate the knowledge of Physical Education students about tooth avulsion (TA) in both dentitions before and after receiving an informative leaflet (IL). Material and Methods: The questionnaire contained information about TA in dentition and its management and was applied to the Physical Education students before and after reading an IL. Results: A total of 118 students, 96.61%, attended a first aid course, and 17.80% received information about TA. Most students (88.98%) never had an experience with TA, and 90.68% considered its management important. The other questions, before and after reading the IL, respectively, were: would not perform deciduous tooth replantation (42%; 88%); knew how to handle the avulsed permanent tooth (APT) (38%; 92%); knew how to clean the APT (50%; 99%); knew that permanent tooth replantation (PTR) must be immediate (15%; 95%); knew the ideal time to seek for the dentist right after TA without performing PTR (6%; 83%); knew how to store APT (31%; 97%). Conclusion: The knowledge of Physical Education students in this research revealed a limited understanding of dental tooth avulsion. After receiving an informative leaflet, the students showed a significant improvement in knowledge about traumatic avulsion management, including tooth replantation and proper actions.

Introducción: En Cuba ha sido poco estudiado el tiempo que demora el diente, desde que aflora a la cavidad bucal hasta que alcanza el plano oclusal. Objetivo: Determinar la duración de la erupción clínica prefuncional temporal y permanente en la población de Villa Clara. Métodos: Se realizó un estudio epidemiológico descriptivo entre los años 2014 a 2018. Mediante un muestreo polietápico aleatorio simple se obtuvo una muestra de 2 584 niños y adolescentes (520 entre tres meses y cuatro años para la dentición temporal, y 2 064 entre cuatro y 14 años para la permanente), nacidos en la provincia, sin alteraciones del crecimiento general y craneofacial; se observó el brote; se calcularon por medio de la regresión de probit, las edades medias para los dientes brotados sin contacto oclusal y las que habían alcanzado la oclusión. La duración de la erupción clínica prefuncional fue calculada restando las medianas de ambas variables. Resultados: En los dientes temporales demoró más la erupción clínica prefuncional en los 1ros molares (superiores, 0,63; inferiores, 0,62); en los permanentes, en los incisivos centrales inferiores de hombres y mujeres, 1 y 1,07, respectivamente. Conclusiones: La erupción clínica prefuncional para los dientes permanentes osciló entre cuatro meses y un año; para los temporales, entre cuatro y siete meses con diferencias dentarias. Se elaboró una tabla de duración de la erupción clínica prefuncional de los dientes temporales y permanentes ajustada a la población villaclareña.
Introduction: the time the tooth takes to emerge from the oral cavity until it reaches the occlusal plane has been little studied in Cuba. Objective: to determine the duration of temporary and permanent prefunctional clinical tooth eruption in Villa Clara population. Methods: a descriptive and epidemiological study was carried out from 2014 to 2018. A sample of 2,584 children and adolescents who were born in the province without alterations in general and craniofacial growth was obtained through simple random multistage sampling (520 between three months and four years for temporary dentition and 2,064 between four and 14 years for permanent one); the outbreak was observed; the mean ages for teeth eruption without occlusal contact and those that had reached occlusion were calculated by means of probit regression. The duration of the prefunctional clinical eruption was calculated by subtracting the medians of both variables. Results: prefunctional clinical eruption took longer in temporary (upper, 0.63 and lower, 0.62) 1st molars, as well as in permanent lower central incisors of men and women (1 and 1.07, respectively). Conclusions: prefunctional clinical eruption for permanent teeth ranged from four months to one year and for temporary ones between four and seven months presenting dental differences. A table of the duration of the prefunctional clinical eruption of temporary and permanent teeth was created according to Villa Clara population.

Objective@#To describe the prevalence of permanent tooth caries and associated factors among junior high school students in Haikou, and to provide reliable evidence for prevention and control of caries.@*Methods@#A total of 3 573 students from 8 junior high school in Haikou City and towns were selected by the methods of clustered sampling survey. Questionnaire survey and oral health examinations were conducted to analyze the caries rate, mean decayed missing filled tooth (DMFT), filling rate, pit and fissure sealant rate. Logistic regression was used to analyze the influencing factors of caries in permanent tooth.@*Results@#Among the surveyed junior high school students, the caries rate was 47.32%( n =1 691), the mean DMFT was 1.51. The caries rate and mean DMFT were higher in female students (49.59%) than in male students (44.95%), and higher in towns (50.77%) than in urban areas (44.04%), the difference were statistically significant ( χ 2=16.25, 7.72, P <0.05). The filling rate and pit and fissure sealant rate among junior high school students in Haikou were 17.13%, 6.27% respectively. The filling rate and pit and fissure sealant rate were higher in urban areas (18.97%, 7.17%) than towns (15.76%, 5.33%), the difference were statistically significant ( χ 2= 9.57, 5.13, P <0.05). The multivariate Logistic analysis showed that female student, town residence, daily consumption of sweets or sugary drinks (≥1 time), bedtime snack were risk factors for junior high school students suffering from permanent dental caries( OR =1.41, 1.45, 2.63, 2.09, 1.53), while using fluoride toothpaste daily, oral education in school were protective factors( OR =0.44, 0.34)( P <0.05).@*Conclusion@#The caries rate of permanent teeth among junior high school students in Haikou is at high level, but the filling rate of caries and pit and fissure sealant rate are lower. The prevention and treatment of dental caries should be carried out in high risk students, and oral health education in school is also needed to improve the oral health level of junior high school students.

Abstract The aim of the study was to investigate the effectiveness of non-invasive and micro-invasive treatments in active enamel carious lesions in high-caries-risk children. Clinical records of children treated in a dental school setting were retrospectively screened for active enamel carious lesions treated non-invasively (topical fluoride applications, oral hygiene instruction, or dietary guidance) or micro-invasively (sealant). The control of active carious lesions was set as the main outcome established by the combination of inactivation and non-progression of the lesions based on Nyvad and ICDAS criteria, respectively. Individual and clinical factors associated with the outcome were analyzed by Poisson regression. The sample consisted of 105 high-caries-risk children with a mean age of 8.3 (± 2.4) years. From a total of 365 active enamel carious lesions, most lesions (84.1%) were active non-cavitated carious lesions (ICDAS scores 1 and 2) and only 15.9% presented localized enamel breakdown (ICDAS score 3). Of these, 72.6% were inactivated and 92.1% did not progress (mean time of 6.5 ± 4.1 months). The prevalence of controlled carious lesions was higher among children older than 6 years (PR:1.43; 95%CI:1.00-2.03; p = 0.04) and in those with better biofilm control (PR:0.99; 95%CI: 0.98-0.99; p = 0.03). Non-operative approaches are effective for controlling active enamel carious lesions. The majority of active enamel carious lesions became inactive and did not progress after treatment. Caries control was associated with older children and better biofilm control.

Abstract A multicenter, randomized controlled clinical trial evaluated the effectiveness of two treatments for deep caries lesions in permanent molars - selective caries removal (SCR) to soft dentin with restoration in a single visit, and stepwise excavation (SW) - regarding pulp vitality for a 5-year follow-up period. The present study aimed to determine the cost-effectiveness of these treatments. Treatments were conducted in two Brazilian cities (Brasília and Porto Alegre). At baseline, 299 permanent molars (233 patients) were treated and 229 teeth (174 patients) were evaluated after 5 years. The discounted cash flow method was adopted. The total cost of each treatment was calculated, and the failure cost (endodontic treatment + restoration) was added to the final cost, according to the 5-year failure rates of each therapy (20% for SCR and 44% for SW). A public health service unit composed of three dentists in 4-hour work shifts was used to calculate the monetary value of the treatments, assuming a total of 528 treatments/month. Considering the 229 teeth evaluated after 5 years (115 SCR and 114 SW), SCR provided savings of 43% (amalgam) and 41% (resin composite) per treatment, compared to SW. The SCR technique provides benefits for public finances (direct economy) and for public health services (increase in the number of treatments performed). Considering that maximizing profit and reducing costs are powerful motivating factors for adopting a certain treatment, this study provides data to better support the decision-making process, regarding the management of deep caries lesions in permanent molars.

ABSTRACT Objective: To evaluate the 24-month clinical performance of composite resin restorations with and without polyethylene fiber in the first permanent molars of pediatric patients with extensive caries. Material and Methods: In total, 75 Class II restorations were placed in the permanent molar teeth of 75 children (mean age 11.3 years) with (FC; n=38) or without (C; n=37) fiber. One operator placed all the restorations. The restorations were evaluated using the modified USPHS criteria in terms of retention, color match, marginal discoloration, anatomic form, marginal adaptation, secondary caries, and postoperative sensitivity. Statistical data were analyzed using chi-square and Cochran tests (p<0.05). Results: At the end of two years, 65 restorations (FC:31; C:34) were followed up. No changes were observed during the first six months. After 24 months of follow-up, there were minor changes in marginal adaptation and marginal color in both groups; however, no statistically significant difference was observed between the clinical performances for all criteria (p>0.05). Conclusion: Extensive composite restorations with or without fibers displayed good clinical performance in high load-bearing areas after 24 months.

Aim: To determine the type and frequency of sequelae in permanent teeth as a result of traumatic dental injuries in primary teeth in pediatric patients attended to at the Hospital Base Valdivia, between 2007 and 2012. Material and Methods: A descriptive study was conducted. The medical records of pediatric patients who were affected by traumatic dental injuries in primary teeth and went to the Sub-department of Dentistry of the Hospital Base Valdivia, Chile, were selected according to inclusion and exclusion criteria. The recorded data was: age of the child at the time of the accident, gender, affected primary tooth, type of traumatic dental injuries, and diagnosis of the permanent successor tooth. Descriptive statistics were performed. A chi-square test was used to establish differences between type of traumatic dental injuries and condition of the permanent tooth. Results: The most frequent diagnosis of traumatic dental injuries in primary dentition was subluxation. The primary tooth with the highest frequency of traumatic dental injuries was the right maxillary central incisor; 58.2% of the permanent successors presented some developmental disturbances. The most frequent sequelae observed in permanent teeth were chronological alterations of the eruption. Conclusion: There is a high frequency of sequelae in permanent dentition as a result of trauma in primary dentition. The most frequent sequel observed was chronological alteration of the eruption. It is fundamental to inform parents about the possible consequences that could arise and emphasize the importance of attending periodic follow up in order to prevent or minimize possible sequelae in permanent teeth.

Abstract: This research aims to provide updated information on caries experience and associated risk factors in children 6-12 years old. A cross-sectional and descriptive study design was carried out with a non-probabilistic, convenient sample of 209 children male and female. Clinical examinations were performed by calibrated dental students following WHO detection criteria. Caries indices dmft and DMFT were calculated. Caries Risk Assessment data was collected using an adapted CAMBRA instrument; following the International Caries Care guidelines. Descriptive statistics were performed to analyze the results and Chi-square test, Contingency Coefficient (C) and Corrected Typified Residues were calculated to determine the association between variables. 58% of the total population had dental caries lesions in its more severe stages (cavitation) and 42% were apparently healthy (AHS) without any cavitated lesions. The mean dmft index was 1.34 ± 1.93, and the mean DMFT index was 0.63 ± 1.22. Lesion severity remained between 1-2 teeth affected on both dentitions. A statistically significant association (p = 0.035) between the health condition and toothbrushing was stablished with a degree of dependence of C = 0.144. A positive standardized residual of 2.1 was evident for schoolchildren that experience caries lesion that never brush their teeth and AHS that brushed their teeth more than once. No association (p = 0.081) was found between health condition and intake of sugary snacks and beverages. A severe dental caries experience with a statistically significant association between the health condition and toothbrushing with fluoridated toothpaste 1450 ppm > 1 a day and a positive correlation in schoolchildren that experience caries lesion that never brush their teeth.

Abstract The aim of this study was to determine the prevalence of dental trauma in schoolchildren 6 to 12 years of age and associated clinical, sociodemographic, and socioeconomic variables. A cross-sectional study was conducted in 477 children from public elementary schools in four locations in Mexico. The dependent variable was dental trauma, which was dichotomized in 0 = without dental trauma and 1 = with dental trauma. For the statistical analysis, a multivariate binary logistic regression model was generated in Stata. Average age was 9.06±1.94 years and 51.1% were girls. The prevalence of dental trauma was 18.2%. Falls, automobile accidents and sports had the highest number of instances (p < 0.01). In the multivariate model, it was observed that the risk of dental trauma increased with age (OR = 1.28) and among boys (OR = 1.45). Schoolchildren with decreased overjet (OR = 0.38) had lower dental trauma. Father's age (OR = 1.03) and educational level (OR = 1.78) were associated with dental trauma. Schoolchildren without health insurance (OR = 0.62) presented dental trauma less often. This study provided important information regarding the association of different sociodemographic, socioeconomic and clinical variables with dental trauma in Mexican schoolchildren. Identifying factors associated with dental trauma may support health promotion opportunities to ameliorate the prevalence of dental trauma.

ABSTRACT Purpose: to measure the total time of mastication and oral phase of swallowing in healthy elderly people, considering different food consistency, the presence of natural teeth, and the type of prosthetic oral rehabilitation, as well to compare dental conditions and consistencies. Methods: a cross-sectional study with 57 healthy elderly people, aged between 60 and 82 years, divided into: dentate group (D) (n=15); and rehabilitated groups; PD: fixed or removable partial dentures in one or both arches (n=15); CRD: maxillary and mandibular complete removable dentures (n=15); ISCD: complete dentures - maxillary removable denture and mandibular implant-supported dentures (n=12). The duration time (seconds) of chewing and of the oral phase of swallowing was measured in the consistencies: solid (a roll slice), pudding (10 ml) and liquid (10 ml). Results: healthy dentate elderly subjects had the following intervals: liquid=1.07±0.35 s; pudding=3.48±1.76 s; and solid=27.88±7.11 s. Statistically significant differences were observed between the D and ISCD groups (p=0.0056) and between D and CRD (p=0.0056) for liquid. For all groups, there was a statistically significant increase between liquid and solid consistencies and between pasty and solid ones (p<0.001). Conclusions: the dentate elderly had shorter oral phase time of swallowing for liquids than the rehabilitated edentulous elderly, but not different from the elderly with partial dentures. Chewing and swallowing time for solid food was longer than that for the other consistencies, regardless of dental condition.
RESUMO Objetivo: mensurar o tempo total da mastigação e da fase oral da deglutição em idosos saudáveis, considerando diferentes consistências alimentares, a presença de dentes naturais e o tipo de reabilitação oral protética, bem como realizar comparação entre as condições dentárias e as consistências. Métodos: estudo transversal com 57 idosos saudáveis, entre 60 e 82 anos, distribuídos em grupo dentado (D) (n=15) e grupos reabilitados: próteses parciais fixas ou removíveis em uma ou ambas as arcadas (PP) (n=15); prótese total removível maxilar e mandibular (PTR) (n=15); prótese total - prótese removível superior e prótese implanto-suportada inferior (PTIS) (n=12). O tempo de duração (segundos) da mastigação e da fase oral da deglutição foi medido nas consistências: sólida (pão francês), pudim (10 ml) e líquida (10 ml). Resultados: idosos dentados saudáveis apresentaram os intervalos: líquido=1,07±0,35 s; pudim=3,48±1,76 s; e sólido=27,88±7,11 s. Foram observadas diferenças estatisticamente significativas entre os grupos D e PTIS (p=0,0056) e entre D e PTR (p=0,0056) para líquido. Para todos os grupos, houve aumento estatisticamente significante entre as consistências líquida e sólida e entre pastosa e sólida (p<0,001). Conclusões: idosos dentados apresentaram menor tempo de fase oral da deglutição para líquidos do que idosos edêntulos totais reabilitados, mas não diferente dos idosos com prótese parcial. O tempo de mastigação e deglutição do alimento sólido foi maior que o das demais consistências, independente da condição dentária.
Résumé
Abstract Dental trauma is considered a complication in oral health, which has attracted the attention of researchers, as its prevalence has increased in recent years. Dental trauma in primary dentition can lead to early tooth loss and impairment of permanent successor teeth, depending on the stage of development of the tooth germ. The aim of the present study was to describe a clinical case of a 4-year-old child who was referred to a pediatric dentist after dental trauma and early loss of deciduous teeth. During the anamnesis, it was observed that the upper deciduous teeth (#51 and #61) were affected by successive traumas, resulting in the early loss of the affected teeth. Nance arch device with a tube-bar system was selected to restore function and aesthetics to the child, while the eruption of the successor permanent teeth was monitored. During the follow-up period, a delay in the eruption of #21 tooth was observed, and ulectomy of the region was indicated to allow the tooth eruption and the proper alignment of the central incisors, which occurred after 5 months of the surgical procedure. Through this report it was possible to conclude that the early diagnosis and the long-term periodic control of traumatic dental lesions in the primary dentition are of fundamental importance to prevent and minimize the damages that can occur to the permanent dentition.

Resumo O traumatismo dentário é considerado uma complicação à saúde bucal que vem chamando a atenção de pesquisadores, pois sua prevalência tem aumentado nos últimos anos. O trauma dentário na dentição decídua pode ocasionar a perda precoce dos dentes, e comprometimento dos dentes sucessores permanentes, dependendo do estágio de desenvolvimento do germe dentário. O objetivo do presente estudo foi descrever um caso clínico de uma criança de 4 anos de idade que foi encaminhada ao odontopediatra após traumatismo dentário e perda precoce de dente decíduo. Durante a anamnese, foi observado que os dentes decíduos incisivos superiores (#51 e #61) foram afetados por sucessivos traumas, resultando na perda precoce dos dentes afetados. O dispositivo arco de Nance com sistema do tipo tubo-barra foi selecionado para devolver função e estética à criança, enquanto a irrupção dos dentes permanentes sucessores foi acompanhada. Durante consulta de controle, um atraso na erupção do dente #21 foi observado e a ulectomia da região foi indicada para permitir a irrupção do dente e o alinhamento adequado dos incisivos centrais, que ocorreu após 5 meses do procedimento cirúrgico. Por meio do presente relato foi possível concluir que o diagnóstico precoce e o controle periódico a longo prazo das lesões dentárias traumáticas na dentição decídua são de fundamental importância para prevenir e minimizar os prejuízos que podem ocorrer à dentição permanente.

O objetivo deste trabalho foi comparar a cronologia de erupção do primeiro molar permanente em crianças de ambos os sexos, residentes na zona urbana e rural do munícipio de Santa Helena - PR, Brasil. Foi realizado um estudo transversal com 154 crianças da zona rural e 300 crianças da área urbana de 04 a 07 anos (48 a 84 meses). Os primeiros molares avaliados foram considerados irrompidos quando qualquer porção de sua coroa estivesse clinicamente visível. A média de idade para erupção do primeiro molar permanente se mostrou de 72 a 83 meses. Destes, o grupo da zona rural apresentou uma média para idade de erupção mais precoce. Contudo, verificou-se um resultado considerável em crianças na faixa de 48 a 59 meses (4 anos), mostrando mais uma vez a erupção precoce nas crianças da zona rural. Este dente irrompeu primeiro na mandíbula, irrompendo primeiro nas meninas do que nos meninos, e o dente 46 foi o que mais se mostrou presente. A média de idade para erupção do primeiro molar permanente correspondeu àquela descrita pela literatura aos seis anos, mas não correspondeu ao atraso na erupção das crianças residentes em zona rural. Bem como este dente irrompeu primeiro na mandíbula... (AU)
The objective of this study was to compare the chronology of eruption of the first permanent molar in children of both sexes, living in the urban and rural areas of the city of Santa Helena-PR, Brazil. A cross-sectional study was carried out with 154 children from the rural area and 300 children from the urban area from 4 to 7 years old (48 to 84 months). The first molars evaluated were considered erupted when any portion of their crown was clinically visible. The average age for eruption of the first permanent molar was 72 to 83 months. Of these, the rural group had an earlier average age for eruption than the urban group. However, a considerable result was found in children 48-59 months showing once again the early eruption in rural children. This tooth erupted first in the jaw, erupting first in girls rather than boys, and tooth 46 was most present. The mean age of eruption of the first permanent molar corresponded to that described in the literature at age six, but did not correspond to the delayed eruption of children living in rural areas. Just like this tooth erupted in the jaw first... (AU)

ABSTRACT Objective: To evaluate the prevalence of caries stages and interventions on first permanent molars (FPM) in Brazilian children. Material and Methods: Data from FPM were extracted from dental records of children aged 5-14 years of age that attended the UERJ Pediatric Dentistry Clinic. Data include patient age, sex, biofilm index, presence of carious lesions in all stages, and the treatments. Data was analyzed using the SPSS® 20.0 program. Results: A total of 158 dental records were analyzed, 587 registers were related to the caries stage and 601 related to the interventions; mean age of 8.26 (±1.4 years) and 53.2% were girls. The prevalence of active/inactive white spot(AWS/IWS) varied from 14.3% to 21.6% in right upper and lower left FPM, respectively. Enamel/dentin lesions without pulp involvement were also more prevalent in the lower arch and ranged from 3.4% for the right upper to 11.5% for the lower right FPM. Cavities with pulp involvement or indicated extraction ranged from 0% to 1.4%. Treatment included dental sealants, varying from 17.1 to 24.0% (n=126) and restorations, varying from 1.3 to 11.8% (n=38). The lower right were the most affected teeth. Conclusion: First permanent molars presented a higher prevalence of dental caries in early stages and the most prevalent treatment was related to the initial carious process, fluor therapy and sealants.

RESUMEN Introducción: en la práctica clínica ortodóncica es de capital importancia el conocimiento de la erupción dentaria. Este es un proceso largo e íntimamente relacionado con el crecimiento y desarrollo del resto de las estructuras craneofaciales. Objetivo: caracterizar el ritmo de brote de los distintos grupos dentarios en niños con dentición permanente de la Escuela «Vietnam Heroico¼, en Santa Clara, desde marzo de 2016 a febrero de 2017. Métodos: se realizó un estudio epidemiológico, descriptivo, longitudinal y prospectivo, en niños de la Escuela «Vietnam Heroico¼, en Santa Clara, desde marzo de 2016 a febrero de 2017. El universo de estudio estuvo constituido por 506 niños de ambos sexos, entre 5 y 13 años de edad. La muestra quedó finalmente conformada por 142 individuos. Se obtuvieron valores medios ponderados del ritmo de brote mensual para cada grupo dentario, y la media de la duración clínica de la erupción según sexo y raza de los pacientes. Resultados: se encontraron diferencias entre arcadas y hemiarcos en cuanto al ritmo de brote. Los dientes maxilares erupcionaron más rápido que los mandibulares. Las féminas fueron más adelantadas en el ritmo de brote en incisivos centrales y primeros molares, y más retrasadas en primeras bicúspides superiores e inferiores, caninos inferiores e incisivos laterales superiores. Conclusiones: el canino y primer premolar presentaron el mayor ritmo de brote en ambos maxilares. No se encontraron diferencias significativas entre los sexos. La duración clínica de la erupción fue menor en la raza negra y demoró aproximadamente seis meses en ambos sexos.
ABSTRACT Introduction: knowledge of tooth eruption is of great importance in clinical orthodontic practice. This is a long process closely related to the growth and development of the rest of the craniofacial structures. Objective: to characterize rhythm of tooth eruption of the different dental groups in children with permanent dentition at "Vietnam Heroic" School, in Santa Clara, from March 2016 to February 2017. Methods: an epidemiological, descriptive, longitudinal and prospective study was conducted on children from Vietnam Heroic" School in Santa Clara from March 2016 to February 2017. The study universe consisted of 506 children of both genders, between 5 and 13 years of age. The sample was finally made up of 142 individuals. Weighted average values of the monthly rhythm of tooth eruption for each dental group were obtained, and the average clinical duration of tooth eruption according to gender and race of the patients. Results: differences were found between arcades and hemiarchs in terms of rhythm of tooth eruption. Maxillary teeth erupted faster than mandibular ones. Females were more advanced in the rhythm of tooth eruption in central incisors and first molars, and more delayed in upper and lower first bicuspids, lower canines and upper lateral incisors. Conclusions: canine and first premolar presented the highest rhythm of tooth eruption in both jaws. No significant differences were found between the genders. The clinical duration of tooth eruption was shorter in black people and it took approximately six months in both genders.

Hereditary gingival fibromatosis (HGF) is a rare genetic condition characterized by slow and progressive gingival enlargement. The gingival overgrowth often delays teeth eruption and may cause serious functional and aesthetic problems. We reported a case of a 10-year-old female child presenting a generalized gingival enlargement covering almost all the maxillary and mandibular teeth and resulted in problems for swallowing, speaking, and poor aesthetics. An incisional biopsy was performed and revealed a hypocellular and hypovascular dense collagenous tissue covered by squamous epithelium exhibiting acanthosis and elongated rete ridges. The diagnosis was HGF. The treatment instituted was an association of gingivectomy with a rigorous program of oral hygiene and follow-up. Herein, we describe a rare non-syndromic case of generalized HGF, including clinical and microscopical features, as well as highlighting the importance of correct diagnosis of this genetic condition.
