ABSTRACT: The aim of this study was to investigate the dimensional structure of the Oral Health Impact Profile-14: (OHIP-14). Data was obtained from studies carried out in Rio de Janeiro (N = 504) and Carlos Barbosa (N = 872), in the State of Rio Grande do Sul, Brazil. Exploratory factor analysis (EFA) was performed to identify the latent dimensions of the OHIP-14. Confirmatory factor analysis (CFA) was carried out of both samples to compare the one-dimensional structure found by the EFA and the proposed three-dimensional structure. This factorial structure was assessed using goodness-of-fit indices. In the Rio de Janeiro study, the eigenvalue was 9.2 and this one factor explained 65.6% of total variance, while in the Carlos Barbosa study the eigenvalue was 7.9 and this one factor explained 56.6% of variance. CFA indicated an adequate fit of the one-factor model for the Rio de Janeiro study (RMSEA = 0.04; CFI = 0.98; TLI = 0.98) and for the Carlos Barbosa study (RMSEA = 0.05; CFI = 0.97; TLI = 0.97). Our findings suggest that the OHIP-14 measures one single construct.

ABSTRACT: OBJECTIVES: To assess the effects of fluoride (F) toothpastes on the prevention of dental caries in the primary dentition of preschool children. STUDY DESIGN: Systematic review and meta-analysis. METHODS: A search for randomized or quasi-randomized clinical trials was carried out, without idiom restraints, in six electronic databases, registers of ongoing trials, meeting abstracts, dentistry journals and reference lists of potentially eligible studies. The search yielded 1932 records and 159 full-text articles were independently read by two examiners. Data regarding characteristics of participants, interventions, outcomes, length of follow-up and potential of bias were independently extracted by two examiners on the basis of predetermined criteria. Any disagreement was solved by consensus after consulting a third examiner. Pooled prevented fractions (PF) and relative risks (RR) were estimated separately for studies testing low F toothpastes (<600 ppm) and those testing standard F toothpastes (1000-1500 ppm). RESULTS: Eight clinical trials fulfilled the inclusion criteria and most of them compared F toothpastes associated with oral health education against no intervention. When standard F toothpastes were compared to placebo or no intervention, significant caries reduction at surface (PF = 31%; 95% CI 18-43; 2644 participants in five studies), tooth (PF = 16%; 95% CI 8-25; 2555 participants in one study) and individual (RR = 0.86; 95% CI 0.81-0.93; 2806 participants in two studies) level were observed. Low F toothpastes were effective only at surface level (PF = 40%; 95% CI 5-75; 561 participants in two studies). CONCLUSION: Standard F toothpastes are effective in reducing dental caries in the primary teeth of preschool children and thus their use should be recommended to this age group.

ABSTRACT: Studies in the dental literature do not yet provide conclusive evidence for the functional and psychosocial benefits of orthodontic treatment. In this cross-sectional study, we aimed to assess the oral health-related quality of life of young Brazilian adults, aged 18 to 30 years, who had completed orthodontic treatment compared with untreated subjects waiting for treatment.
The subjects were recruited at a state-funded university clinic. The sample comprised 100 patients in the retention phase of orthodontic treatment for more than 6 months (treated group) and 100 persons who were seeking orthodontic treatment and were still on a waiting list (nontreated group). Data were collected by using the oral health impact profile, the index of orthodontic treatment need (malocclusion severity and esthetic impairment), the Brazilian economic classification criteria (socioeconomic status), and the index of decayed, missing, and filled teeth (oral health status). Statistical analyses were performed by using chi-square and Fisher exact tests and negative binomial regression.
The mean oral health impact profile scores were 3.1 (SD ± 2.99) and 15.1 (SD ± 8.02) in the treated and nontreated groups, respectively. The most frequent impacts in the treated and nontreated groups were "painful aching" and "been self-conscious," respectively. Comparisons between the groups were controlled for malocclusion severity, clinician-assessed esthetic impairment, age, sex, socioeconomic status, and oral health status. Nontreated young adults had mean oral health impact profile scores 5.3 times higher than did the treated subjects.
Young Brazilian adults who received orthodontic treatment had significantly better oral health-related quality of life scores in the retention phase, after treatment completion, than did nontreated subjects.

ABSTRACT: Some of the basic dental health practices that are recommended to the public by professionals are not evidence based. Incorrect oral health messages may adversely affect children's oral health behaviours.
To identify and list the recommendations concerning children's oral hygiene practices provided by dental and paediatric organisations, and to assess how these recommendations relate to the scientific evidence currently available.
Cross-sectional. The authors contacted professional organisations in ten countries requesting items (brochures, leaflets or folders) containing messages on children's oral hygiene practices. They then listed these recommendations and assessed how they related to scientific evidence obtained from systematic reviews available at PubMed and the Cochrane Library.
Fifty-two of 59 (88%) organisations responded to our request and 24 dental health education materials were submitted to the authors. They mentioned recommendations on oral hygiene practices for children, such as toothbrushing frequency, supervision and technique; when to start and how long toothbrushing should last; toothbrush design and replacement; flossing; gums/teeth wiping; tongue cleaning; type and amount of toothpaste and advice on toothpaste ingestion. The search at PubMed and the Cochrane Library resulted in 11 systematic reviews addressing these topics.
Several oral hygiene messages delivered by professional organisations showed inconsistencies and lacked scientific support.

ABSTRACT: The aims of this study were to detect whether recommendations concerning oral hygiene practices for children among Brazilian health agencies are consistent and to verify whether possible inconsistencies in these recommendations might be associated with an apparent gap in the scientific evidence. Fifty-four Brazilian health agencies were contacted by mail or electronic mail and were asked to send any material containing recommendations on oral hygiene practices aimed at children. A search was subsequently carried out on the Cochrane Oral Health Review Group and PubMed-Clinical Queries websites in order to assess the scientific evidence available on this subject. Forty (74%) agencies answered and 21 materials containing oral hygiene recommendations were obtained. Eleven pertinent systematic reviews were identified. This preliminary study detected some conflicting and not evidence-based oral hygiene messages, which emphasizes the need to carry out and disseminate systematic reviews on these controversial issues in order to bridge the gap between knowledge and practice.

ABSTRACT: The aim of this study was to verify whether sucking habits influence the position of the primary incisors. The sample comprised 34 preschool children (mean age 44 months ± 9 months). They were divided into three groups: group B (n=9) with a baby bottle habit; group BP (n=13) with baby bottle and pacifier habits; and a control group C (n=12) with no sucking habit. Data were derived from face-to-face interviews with the parents/guardians, oral examinations, study casts, facial photographs (frontal/lateral views), and cephalograms. The cephalograms were scanned and subsequently analyzed by one trained and calibrated operator. The cephalometric parameters recorded were: interincisal angle (U1/L1), U1/NA (angle/distance), and L1/NB (angle/distance). The data were analyzed using Stata 7.0. The Kruskall-Wallis test was used to compare the cephalometric measurements in the children with and without sucking habits. The level of significance was set at P≤.05. This study found a significant relationship between existing sucking habits and a protrusion of the maxillary and mandibular primary incisors.

ABSTRACT: To assess the effects of oral pain on oral health-related quality of life during pregnancy and document measures taken by pregnant women seeking relief for oral pain. Their experience of other types of pain were also investigated.
A sample of pregnant women who were admitted to a public hospital to give birth were invited to participate in this cross-sectional study. Those who agreed were asked if they had experienced any pain due to problems with their mouth, teeth, or dentures during the 6 months prior to the interviews. Interviewees who answered affirmatively were questioned about the effects of this pain on their normal activities with the Oral Impacts on Daily Performances (OIDP) tool.
The study population consisted of 504 subjects (83% of the eligible individuals). A high prevalence of untreated dental caries was found. The prevalences of oral pain, headaches, back pain, and pelvic pain were 39.1%, 61.5%, 59.3%, and 60.9%, respectively. Of those reporting pain, 168 (33.3%) reported having had difficulty doing at least one of the activities included in the OIDP due to oral pain. The most frequently mentioned effects were difficulty in maintaining emotional balance (23.6%), difficulty eating (22.8%), and difficulty cleaning teeth (20%). The mean and median OIDP scores were 13.9% and 8.0%, respectively.
Oral pain during pregnancy was an important problem for this group of women and had a negative effect on their quality of life.

ABSTRACT: The term amelogenesis imperfecta is applied to a clinically heterogeneous group of hereditary disorders that interfere with the normal development of dental enamel. These disorders cause a deficiency in the enamel's quantity and/or the quality that may result in poor dental esthetics. The purpose of this paper was to describe a case of hypoplastic amelogenesis imperfecta in an 8-year-old girl whose dissatisfaction with the appearance of her teeth led to impaired social functioning. Since the patient was in the mixed dentition stage, a temporary treatment aiming to improve dental esthetics, preserve oral function, and allow for the recovery of the patient's self-confidence was performed by a multidisciplinary team.
