We conclude that the FPC and BLS are simple and effective for the treatment of anterior open bite, with the advantage given to the FPC.

his study compared the caries index (dmft), presence of sucking habits and facial alterations in children attended by the preventive program for infants and children assisted by spontaneous demand, at the same age, at the public sector of Maringá, PR. A total of 100 children were evaluated (1-6 years), who were divided into 2 groups: GI -children attended by the infant program with educational and preventive care and bimonthly follow-up, since the 1 st year of age; GII -children assisted for conventional treatment (preventive and restorative) according to the needs, and follow-up as requested by the parents. Data collection was performed by interview with the parents and clinical examination for evaluation of the dmft and facial alterations. Analysis of data (Mann-Whitney test for dmft comparison and chi-square test for all other comparisons) demonstrated a significant difference (p<0.05) in relation to the dmft index (GI: 0.2; GII: 3.0), percentage of caries-free children (GI: 88%; GII: 57%) and non-nutritive sucking habits (GI: 47%; GII: 75%). The breastfeeding and bottle utilization practices were similar for both groups. Facial alterations were more frequently observed (p<0.05) in GII (48%) than GI (8.4%), especially for the variables (p<0.05) high arched palate (GI: 10.2%; GII: 35.4%), anterior open bite (GI: 14.2%; GII: 35.4%) and mouth breathing (GI: 6.1%; GII: 29.1%). It was concluded that the infant program is more effective than the spontaneous demand program, reaching the goal of oral health maintenance in the child population.

Foram avaliadas 100 crianças (1-5 anos), divididas em 2 grupos: GI-crianças atendidas no programa de bebês com atendimento educativo-preventivo e retornos bimestrais, desde o 1º ano de vida; GII-crianças atendidas para tratamento convencional (preventivo e curativo) de acordo com a necessidade, sendo o retorno responsabilidade dos familiares. A coleta dos dados foi realizada por meio de entrevista com os pais e através de exame clínico, para avaliação do ceo e alterações faciais. A análise dos dados (Teste de Mann-Whitney para comparações de ceo e teste qui-quadrado para todas outras comparações) mostrou diferença significante (p<0,05) em relação ao índice ceo (GI: 0,2; GII:3,0), componente livre de cárie (GI:88%; GII:57%) e hábitos de sucção não nutritiva (GI:47%; GII:75%). As práticas de amamentação e uso da mamadeira foram semelhantes nos grupos. Constatou-se maior presença de alterações faciais (p<0,05) no GII (48%) do que no GI (8,4%), destacando-se as variáveis (p<0,05) palato ogival (GI: 10,2%; GII:35,4%), mordida aberta anterior (GI:14,2%; GII:35,4%) e respiração bucal (GI: 6,1%; GII: 29,1%). Concluiu-se que o programa de at...

Introduction: bonded fixed retainers are often used to stabilize the results obtained with the orthodontic treatment. It is important that they do not prejudice dental health, as they will be used for a long period. Objective: The purpose of the present study was to compare periodontal indexes between two types of bonded fixed retainers, conventional 3 x 3 plain retainer (0.8-mm orthodontic wire, bonded to the canines only) and a manufactured braided retainer (0.2 x 0.7-mm stainless steel wire, bonded to all anterior teeth) after use. Methods: a test group of 15 volunteers (aged from 18 to 25 years) used both the conventional retainer and braided retainer for six months. A randomized longitudinal study design, with a two week washout interval, was applied. The dental plaque index, gingival index and dental calculus index were evaluated. Furthermore, the calculus accumulated along the retainer wire was measured and all patients answered a questionnaire about the use, acceptance and comfort of both types of retainers. Results: the scores for plaque and gingival indexes were higher for the braided retainer (p< 0.05) on the lingual and proximal surfaces. The same occurred with the calculus index on the lingual surfaces (p< 0.05). The calculus index along wire was higher for the braided retainer (p< 0.05). All patients preferred the conventional retainer, and said that it was also more comfortable to use. Conclusion: it was concluded that the conventional retainer showed better periodontal indexes than the braided type.

Este trabalho tem como objetivo fazer uma revisão de literatura sobre a etiologia e as condutas clínicas mais adequadas para realizar diagnóstico e tratamento de crianças com bruxismo. Este hábito tem gerado uma grande preocupação, pois atualmente tem se mostrado cada vez mais presente entre as crianças e repercute de forma significativa no sistema estomatognático quando de forma intensa e prolongada. O bruxismo é considerado uma parafunção, com ranger dos dentes durante movimentos não funcionais do sistema mastigatório, que ocorre tanto durante o dia como a noite. Como conseqüência o bruxismo pode resultar em abrasão dos dentes decíduos e permanentes, podendo causar alterações na dimensão cervico incisal ou oclusal. Pôde-se concluir que este hábito está muito presente no público infantil e sua etiologia é multifatorial no qual o fator psicológico é preponderante, talvez pela presença do medo, tensões e ansiedade entre as crianças. Desta forma, como este hábito é complexo, o tratamento ideal é uma terapia multidisciplinar entre dentistas, psicólogos, médicos para alcançar resultados mais eficientes.Palavras Chaves: Bruxismo; Crianças; Desgaste Dentário.

Objective: To identify the dental anomalies that can modify the occlusal characteristics and their distribution in these occlusal alterations in the skeletal patterns of children. Material and Methods: We analyzed charts, panoramic and periapical radiographs of children aged 5 to 12 years from 2009 to 2012. The facial pattern was evaluated through subjective face analysis and cephalometric data, as well as the occlusion of patients with and without (control) dental anomalies. The relationship between the presence of dental anomalies and malocclusion was analyzed by the Chi-square test with significance level of 5%. Results: 73 children (27.8%) presented dental anomalies, being 49.3% in girls and 50.7% in boys in a total of 88 teeth involved. Anomalies observed in decreasing order were: enamel hypoplasias, eruptive ectopias, agenesis, supernumerary teeth, corono-radicular dilaceration, microdontia, transposition and imperfect amelogenesis. Of these, 22.2% presented associated dental anomalies, whose ectopic eruption with enamel hypoplasia were the most frequently encountered. When comparing the control group with children with dental abnormalities it was observed a significant relationship between the presence of dental anomalies and malocclusion (p<0.05). The most frequent alteration among patients with dental anomalies was deep overbite (24.6%), followed by crowding (23.3%), posterior crossbite (14.2%), anterior open bite (12.9%) and anterior crossbite (0.3%). Conclusion: Dental dysgenesis interferes with the development of occlusion and the resulting occlusal problems are distributed differently, taking into account the skeletal facial pattern in patients with and without dental anomalies.
