Patients' perception of installation, use and results of orthodontic mini-implants.

The purpose of this study was to evaluate patient acceptance and perception of pain with regard to orthodontic mini-implants. The study was conducted on 58 individuals undergoing orthodontic treatment, who had orthodontic mini-implants placed as anchorage devices. Data were collected using a questionnaire containing 6 questions evaluating perception of pain during mini-implant placement and during use, difficulty with cleaning, unaesthetic appearance, difficulty with eating and benefits observed. Data were tabulated and analyzed using Fisher and Spearman's Correlation Coefficient tests. It was found that 94.8% of the patients reported that they would be willing to undergo treatment with mini-implants again. Of the negative aspects evaluated, the most significant was discomfort during placement, while the least significant was difficulty with eating. Patients' perception of aspects related to mini-implants was shown to be independent of the quantity of these devices placed. Although the patients evaluated some aspects of mini-implants negatively, the mean score for benefits observed was very high, indicating good patient satisfaction with treatment.

Effectiveness of varnish with CPP-ACP in prevention of caries lesions around orthodontic brackets: an OCT evaluation.

OBJECTIVE: To evaluate the in vitro efficiency of applying varnish containing casein phosphopeptide (CPP) and amorphous calcium phosphate (ACP) in prevention of caries lesions around orthodontic brackets. MATERIALS AND METHODS: For this purpose, brackets were bonded to the vestibular surface of bovine incisors, and eight groups were formed (n = 15) according to exposure of oral hygiene substances and enamel varnish: 1 (control) brushing only performed, 2 (control) brushing + use of mouth wash with fluoride, 3 Duraphat varnish application only (Colgate-Palmolive Ind. E Com. Ltda, São Paulo, SP, Brazil), 4 Duraphat + brushing, 5 Duraphat + brushing + mouth wash, 6 MI Varnish application (GC America, USA), 7 MI + brushing, and 8 MI + brushing + mouth wash. The experimental groups alternated between pH cycling and the procedures described and were kept in an oven at temperature of 37°C. Both brushing and immersion in solutions was performed in a time interval of 1 minute, followed by washing in deionized water three times a day for 28 days of experimentation. Afterwards, evaluation by optical coherence tomography (OCT) of the special type (Ganymede OCT/Thorlabs, Newton, USA) was performed. In each group, a scanning exam of the white spot lesion area (around the region where brackets were bonded) and depth measurement of caries lesions were performed. RESULTS: Groups 1 and 3 were shown to differ statistically from groups 5, 6, 7, and 8 (p = 0.000). MI Varnish was shown to be more effective in diminishing caries lesion depth, compared with Duraphat, irrespective of being associated with brushing and mouth wash, or not. LIMITATIONS: The major limitation of this study is that it is a study in which demineralization was obtained with the use of chemical products, and did not occur due to the presence of Streptococcus mutans and its acid byproducts. CONCLUSION: Application CPP-ACP-containing varnish irrespective of being associated with brushing and mouthwash, or not, reduced depth of caries lesions around orthodontic brackets.

O objetivo do presente estudo foi avaliar a aceitabilidade e percepção dolorosa dos pacientes em relação aos mini-implantes ortodônticos. Este estudo foi realizado com 58 indivíduos em tratamento ortodôntico que tiveram a instalação de mini-implantes ortodônticos como recurso de ancoragem. Oinstrumento de coleta de dados foi um questionário contendo 8 perguntas que avaliaram a percepção dolorosa durante a instalação e uso dos mini-implantes, dificuldade de higienização,aspecto anti-estético, dificuldade de alimentação e os benefíciosobservados. Os dados foram tabulados e analisados pelos testes de Fisher e de Coeficiente de Correlação de Spearman. Os resultados demonstraram que 94,8% dos pacientes relataram que se submeteriam novamente ao tratamento com mini-implantes.Dos aspectos negativos avaliados, o mais significante foi o incômodo e dor durante a instalação, enquanto o menos significante foi dificuldade de alimentação. A percepção dos pacientes sobre os aspectos relacionados aos mini-implantesmostrou-se independente da quantidade desses dispositivos instalados. Conclui-se que apesar da avaliação dos mini-implantes pelos pacientes ter apresentado alguns aspectos negativos, o escore médio dos benefícios observados foi bastante alto, indicando boa satisfação dos pacientes com o tratamento.
