AIM: To measure torque angle values of brackets designed for canines, comparing it to their prescription values. METHODS: One hundred and sixty maxillary -2o and mandibular -11o canine brackets of Roth prescription from the following brands were selected: Abzil, Eurodonto, Morelli and Ormco. The brackets were set in wax and images were obtained by scanning. Reference points were determined over these images, lines drawn and the torque angle was measured. The Student's t-test and the Wilcoxon signed-rank test were used at a significance level of 5%. RESULTS: For maxillary canine brackets, the medium torque angle values were: Abzil -0.93o ± 0.88o; Eurodonto 0.13o ± 0.34o; Morelli -2.56o ± 0.50o, and Ormco -1.16o ± 1.27o. For mandibular canine brackets, the values were: Abzil -11.76o ± 0.40o; Eurodonto -10.40o ± 0.25o; Morelli -11.18o ± 0.56o, and Ormco -11.36o ± 0.30o. For maxillary canine brackets, the brands Abzil, Morelli, and Ormco presented statistically diferente values from those indicated for prescription. For mandibular canine brackets, the brands Abzil, Eurodonto, and Ormco presented statistically different values from the prescribed ones. CONCLUSIONS: Some marketed brands present differences between the torque angle found in the brackets and those recommended in the prescription. However, these differences are clinically acceptable.

AIM: To verify the presence of Bolton anterior and total discrepancy in Brazilian individuals with natural normal occlusion and Angle's Class I and Class II, division 1 malocclusions. METHODS: The sample was divided in three groups (n=35 each): natural normal occlusion; Class I malocclusion; Class II, division 1 malocclusion. Of the 105 Caucasian Brazilian individuals, 24 were boys and 81 were girls aged from 13 to 17 years and 4 months. The mesiodistal width of the maxillary and mandibular teeth, from the left first molar to the right first molar, was measured on each pre-treatment dental plaster cast using a digital caliper accurate to 0.01 mm resolution. Values were tabulated and the Bolton ratio was applied. The Kolmogorov-Smirnov test was used to verify if data were normally distributed (p>0.2). For comparison between the values obtained and those from the Bolton standard, Student's t test was used and one-way ANOVA was used for comparisons among the 3 groups, with a significance level of 5% (p<0.05). RESULTS: For groups 1, 2 and 3, respectively, the total ratio found was 90.36% (SD 1.70), 91.17% (SD±2.58) and 90.76% (SD±2.45); and the anterior ratio was 77.73% (SD 2.39), 78.01% (SD 2.66) and 77.30% (SD 2.65). CONCLUSIONS: There was no significant difference among the groups regarding the values indicated in the Bolton ratio.

INTRODUÇÃO: após a promulgação e maior divulgação do Código de Defesa do Consumidor (CDC), aumentou o número de conflitos legais entre pacientes e cirurgiões-dentistas, fazendo com que o profissional da saúde passasse a se resguardar cada vez mais quanto ao risco de eventuais processos. Para sua defesa, é indispensável a elaboração de um prontuário clínico adequado e completo, porém, o tempo que esse deve ser guardado é uma incógnita. OBJETIVO: o objetivo do presente estudo é rever a literatura e discutir sobre o tempo de guarda da documentação ortodôntica versus o prazo de prescrição legal, além de propor um modelo de termo de conclusão de serviços odontológicos. CONCLUSÃO: aconselha-se a devolução de parte dos documentos clínicos ao seu legítimo dono mediante recibo discriminado. O "Termo de Conclusão" traduz o conhecimento da conclusão do tratamento pelo paciente e poderia ser considerado termo inicial do prazo prescricional pelo CDC porque nesse consta que o paciente reconhece a qualidade do serviço e o resultado satisfatório.

INTRODUCTION: After promulgation and wider dissemination of the Code of Consumer Protection, there was an increase in the number of legal conflicts between patients and dentists, leading these health professionals to increasingly guard themselves from possible lawsuits. As such, it becomes critical the preparation of an adequate and complete clinical record, even though the keeping time remains uncertain. OBJECTIVE: To review the literature and discuss the keeping time of orthodontic records versus the legal time for their prescription, as well as to propose a model of a Term upon Completion of Dental Treatment. CONCLUSION: It is advised to return part of the clinical records to their rightful owners by means of an itemized receipt. The Term upon Completion reflects the patient's awareness and could be considered by the CCP as the initial term of the prescription time, because it implicates that the patient recognizes the quality of service provided and satisfactory results achieved.
