RESUMO
Abstract: A randomized controlled parallel clinical trial was conducted to evaluate the efficacy of the association of 1.23% topical professional acidulated phosphate fluoride (APF) gel with oral hygiene and dietary instructions on the arrest of active non-cavitated lesions in permanent, mixed, and temporary dentition in children between 3 and 12 years of age. Ninety-eight caries-active children were randomly divided into two groups: a fluoride gel group (n = 49) and a non-fluoridated gel group (n = 49). Each group received up to eight weekly applications of gel, weekly professional toothbrushing with oral hygiene instructions and dietary counselling. Caries lesions were assessed qualitatively through visual-tactile criteria performed in three stages: initial, intermediate, and final. Regression models were applied to identify risk indicators for caries control. Between-group comparison regarding the time taken to arrest the lesions was performed using Chi-squared and Fisher's exact tests. Seventeen children did not receive the allocated intervention, and one was lost to follow-up (n = 80). There was no difference between the control and placebo groups regarding the time to the arrest of the lesion (p >.05). The treatments showed similar results without significant statistical difference (p = 0.33; 95%CI: 0.32-1.48). No adverse effects were observed. It can be concluded that no additional effect of the association of 1.23% APF gel with oral hygiene using fluoride dentifrice and dietary instructions on the arrest of active non-cavitated lesions could be established. We can also confirm the importance of toothbrushing frequency and, consequently, the visible plaque reduction in the control of caries activity. RBR-37V5S3

Abstract: Qualitative approach about the implications that occur succeeding the premature loss teeth is still insufficient. This study aimed to understand the experience of early loss of deciduous teeth in children's lives, from the perspective of their caregivers. Qualitative case study included 52 caregivers of children from an outpatient service of a public university in the south of Brazil. Early loss of deciduous teeth to trauma or caries was identified through analysis of health records, and afterwards, semi-structured interviews were performed. Textual material was interpreted through the content analysis proposed by Bardin, supported by the ATLAS.ti software. The theoretical perspective of stigma was guided according to the principles of the phenomenology of Maurice Merleau-Ponty, centred on the experience of early loss of deciduous teeth as a historic-cultural expression of a social group. According to caregivers, premature loss of deciduous teeth due to trauma or decay brings functional limitations with chewing and speaking, and impairments related to social interaction with other children. The repercussions of missing teeth were not limited to the child's image, but also brought changes in families' daily lives. However, when early tooth loss was due to extraction because of pain and suffering, caregivers perceived the loss as 'commonplace' in children's lives. The understanding of how children see themselves without teeth in their social world for their caregivers, which also includes their family and friends, determines how much experiencing tooth loss affects their lives. Besides, caregivers' perceptions related to early loss of deciduous teeth should be included in strategies of oral health promotion programs.
