Purpose The purpose of this study was to investigate the prevalence of different interproximal contact areas of primary molars, as described in the OXIS classification, in a group of three- to four-year-old caries-free children. Methods This cross-sectional study was carried out with a representative sample of 4,476 contact areas of 1,119 caries-free school children. A single calibrated examiner performed a type III examination to assess the type of contact area between primary molars, as seen from the occlusal view. The contacts were scored as O (open contact), X (point contact), I (straight contact), and S (curved contact) using OXIS classification. The prevalence of the types was expressed in the form of numbers and percentages. The findings were subjected to chi-square and McNemar's tests. Results The most common contact type was I (75.5 percent), followed by S (15.3 percent), O (5.8 percent), and X (3.3 percent). Significant differences were obtained (P less then 0.001) when the inter- arch comparison was performed for all except the X type of contact. Further, 401 (35.8 percent) children had more than one type of contact in dif- ferent quadrants. Conclusions The present study highlights the existence of four different types of interproximal contact areas, O, X, I, and S, in caries-free three- to four-year-olds.Purpose The purpose of this study was to compare approximal carious lesions in dentin diagnosed by clinical examination with those diagnosed radiographically in high caries-risk children. Methods Eighty-four Amish two- to 11-year-olds were evaluated clinically by calibrated examiners using standard epidemiological criteria and radiographically using standard criteria as part of baseline examinations for a two-year pilot clinical trial. Approximal carious surfaces diagnosed by clinical examination were compared to those diagnosed radiographically to determine the number of lesions misdiagnosed by clinical examination alone. Comparisons between the number of lesions detected by clinical exam and radiographic exam were made using McNemar's test. Results Among 124 anterior approximal tooth surfaces, clinical examination alone identified 61 lesions (49.2 percent), while radiograph examination identified 72 lesions (58.1 percent); thus, nine percent of lesions were misdiagnosed by clinical examination alone. For the 412 posterior approximal tooth surfaces included in the study, 101 lesions (24.5 percent) were identified by clinical examination, whereas 229 lesions (55.6 percent) were identified via radiographic examination. Thus, 128 (31.1 percent) were misdiagnosed by clinical examination alone. Conclusions Clinical examinations without radiographs significantly underestimate caries prevalence. Therefore, the use of radiographs should be encouraged in epidemiological studies and clinical trials.Purposes The purposes of this prospective trial were to (1) compare the clinical and radiographic outcomes of three restorative methods -modified atraumatic restorative treatment (mART), the Hall technique (HT), and stainless steel crown (SSC)-in primary molars with multi-surface carious lesions; and (2) assess child behavior throughout these treatments. Methods In this randomized controlled trial (RCT), 123 primary molars in four- to nine-year-old children were randomly divided into treatment groups (HT, mART, and SSC). Tamoxifen molecular weight Variables, including signs of failure, treatment time, child's discomfort, child's behavior, and canine overbite relationship in HT, were recorded immediately after the treatment and at six- and 12-month recalls. Results Failures occurred most significantly for mART at all recalls (P=0.001). The treatment time was significantly higher in SSC. There was no significant difference in the child-assessment of discomfort (P=0.814). The child's behavior, as evaluated by the dentist, however, was significantly better for the SSC group. Alterations to the canine overbite relationship of HT decreased significantly during recalls (P less then 0.001). Conclusions The high success and shorter treatment time of the Hall technique support its consideration as an alternative to the conventional technique for the treatment of carious primary teeth with multisurface lesions. The results for modified atraumatic restorative treatment were not as satisfying.One of the goals of environmental enrichment is to encourage species-typical behaviors, while discouraging abnormal behaviors or stereotypies. Assessing the effectiveness of various enrichment modalities can be challenging, particularly for prey species such as rabbits that exhibit freezing responses in the presence of people. In this study, we housed rabbits in 3 different sized cages and observed their behaviors. The 3 cage sizes were our standard rabbit housing cage, a medium sized cage, and a large run. Based on analysis of the recordings, ethograms were constructed and behaviors were quantified. The rabbits in large runs spent more time performing active, exploratory behaviors (431 ± 74 s) than rabbits in the standard cages(184 ± 55 s). However, space constraints inside research facilities often make it impractical to house rabbits in large runs.Therefore, we decided to explore if enrichment devices could promote the expression of active behaviors, similar to those displayed by rabbits housed in the large runs. We selected 3 devices a hanging toy, a destructible device, and a dig bin. All 3 enrichment devices promoted more time spent performing active, exploratory behaviors (389 ± 48, 463 ± 50, and 420 ± 44 s,respectively), compared with control rabbits housed without an enrichment device (226 ± 53 s). We also analyzed the fecal glucocorticoids of rabbits after shipping or surgery to determine if enrichment devices could mitigate the physiologic impact of these stressors. We found no significant differences in fecal glucocorticoid levels between rabbits that experienced the stressor and rabbits that did not, or between rabbits with or without enrichment devices. Overall, the provision of largercaging and/or addition of enrichment devices encouraged a broad spectrum of active, species-typical rabbit behaviors, suggestiveof improved animal welfare.
