Aspectos orofaciais dos maus-tratos infantis e da negligência odontológicaOrofacial aspects of childhood abuse and dental negligence

The aim of this randomized clinical trial study was to evaluate the therapeutic effect of two varnish formulations (G1 = 5% NaF, G2 = 6% NaF + 6% CaF(2)) on the remineralization of white spot lesions (WSL). The sample was composed of 15 (7- to 12-year-old) children with 45 active WSL in anterior permanent teeth. The children were randomly divided into two groups providing 22 lesions for G1 and 23 for G2. The children were submitted to weekly varnish applications 4 times. The WSL were evaluated twice: baseline and on week 4. Maximum lesion dimensions (mesiodistal and incisogingival) were measured in millimeters and classified in four grades of size. WSL were also assessed regarding lesion activity by one calibrated examiner. The Pearson chi-square and Fisher's exact tests were used (P < 0.01). WSL reductions were observed in both varnish groups (Chi-square = 0.15, d.f. = 1, P = 0.90), and with similar magnitude (in mm): 1.19 and 1.29 for G1 and G2, respectively. Thirty-six WSL (15 in G1 and 21 in G2) were classified as inactive on week 4, reaching an overall value of 80%. No difference was observed between G1 and G2 regarding activity scores (Fisher's exact test, p > 0.01). It was concluded that after 4 applications the two varnish formulations tested produced similar clinical effects, indicating the reduction and the control of carious activity in most WSL.

To evaluate the knowledge of public daycare center teachers of the city of João Pessoa, PB, Brazil, about child oral health Method: Using an extensive direct observati on, a questi onnaire with objecti ve questi ons was used, aft er being pre-tested with 10% of the sample in a pilot-study. The sample size was calculated using the stati sti cal soft ware DIMAM 1.0 wih 95% confi dence level, 10% error and 50% power, corresponding to 54 professionals out of a populati on of 118 teachers registered at the Municipal Secretariat of Educati on. Data were analyzed by descripti ve stati sti cs using the SPSS v.11.0 stati sti cal soft ware. To evaluate the level of informati on of the preschool teachers, a frequency of 0 to 50% of correct answers were considered as unsati sfactory knowledge, 50 to 70% was considered as reasonable knowledge, and above 70%, as sati sfactory knowledge. Results: All parti cipants reported to have knowledge of Preventi ve Denti stry, and the denti st was considered as the main source of informati on about the subject (31.5%). The teachers knew adequately the meaning of dental biofi lm and its removal in 31.5% and 7.4% of the cases, respecti vely. Only 51.9% of the interviewees were aware of the multi fatorial eti ology of caries and 55.6% believed that this pathology was not transmissible. When asked about Preventi ve Denti stry, 98.1% of the teachers believed that fl uoride have preventi ve eff ect, 92.6% knew the characteristi cs of an adequate toothbrush, and 94.4% considered the toothbrushing technique as important for a correct oral hygiene. Conclusion: The teachers evaluated in this study presented limited knowledge of dental caries, but sati sfactory knowledge of preventi on of this pathology.
