Objectives: The aim of the present study was to assess the psychometric properties and level of agreement between the self-administered and interviewer-administered Child Perceptions Questionnaire (CPQ) for children between 8 and 10 years of age (CPQ 8-10) and between 11 and 14 (CPQ 11-14) years of age. Methods: A randomized cross-over study was carried out, involving 180 children (Group 1 - 90 children between 8 and 10; Group 2 - 90 children between 11 and 14 years of age) in the state of Minas Gerais, Brazil. All children completed both administration modes of the CPQ; half of each group received interviewer-administered mode first [Subgroup A (CPQ 8-10n = 45) and Subgroup C (CPQ 11-14n = 45)], and the other half performed the self-administered mode first [Subgroup B (CPQ 8-10n = 45) and Subgroup D (CPQ 11-14n = 45)]. Test-retest reliability of each mode of administration was tested on 60 children (30 for CPQ 8-10; 30 for CPQ 11-14), who were not included in the other analyses. The level of agreement between scores on the self-administered and interviewer-administered versions of the CPQ 8-10 and CPQ 11-14 was established using the intraclass correlation coefficient (ICC). The order of presentation of both instruments was tested considering the four subgroups (A, B, C and D). The calculation of effect size proposed by Cohen (1992) was used to test the clinical significance of the findings. Results: Both the self-administered and interviewer-administered versions of CPQ 8-10 and CPQ 11-14 demonstrated acceptable psychometric properties. Agreement between the administration modes for the CPQ 8-10 and CPQ 11-14 was 0.90 and 0.88 (ICC), respectively. With the exception of the functional limitation subscale, the scores of the subscales and overall score on the CPQ 8-10 were significantly higher in the group of children who responded to the interviewer-administered measure first. With the CPQ 11-14, statistically significant differences were found only for the emotional well-being subscale. Conclusions: Both administration modes of the CPQ 8-10 and CPQ 11-14 demonstrated satisfactory psychometric properties and a high level of agreement. Although statistically significant differences were observed for oral symptoms, emotional well-being and social well-being, with the first administration of the interviewer-administered version, the effect of the order of administration had small to medium effects on the CPQ scores. © 2011 John Wiley & Sons A/S.

This study aimed to evaluate the psychometric properties of the Brazilian version of the Early Childhood Oral Health Impact Scale (ECOHIS). A total of 247 children aged 2 to 5 years and their parents/guardians participated in this study. A clinical oral examination was performed and the parents/guardians completed the ECOHIS questionnaire. Within a period of four-weeks, 20% of the participants repeated the ECOHIS questionnaire. Construct validity was determined using Spearman's rank correlation. Discriminant validity, internal consistency and test-retest reliability were also evaluated. The children were divided into 2 groups: group 1 (with dental caries) and group 2 (caries-free). Children with caries showed higher mean ECOHIS scores than the caries-free children. The child impact section (p < 0.01), family impact section (p < 0.01) and total ECOHIS scores (p < 0.01) were significantly correlated with tooth decay. Cronbach's alpha coefficients demonstrated satisfactory internal consistency. The Brazilian version of the ECOHIS is a valid instrument for assessing oral health-related quality of life in preschool children with Brazilian Portuguese-speaking primary caregivers.

Background/Aim: The joint evaluation of oral health-related quality of life and traumatic dental injury (TDI) is an important tool for setting priorities in public oral health programs. The purpose of the present study was to compare the impact of treated TDI, untreated TDI, and absence of TDI on the quality of life of schoolchildren aged 11-14 years. Material and methods: A cross-sectional study was carried out with 668 schoolchildren from the city of Diamantina, Brazil. The clinical examination involved the determination of the presence and type of TDI based on the criteria proposed by O'Brien. Malocclusion was evaluated using the criteria of the Dental Aesthetic Index, and dental caries was diagnosed using the DMFT/dmft index. The impact of TDI on quality of life was assessed using the Child Oral Impact on Daily Performances (Child-OIDP). The outcome was the absence (Child-OIDP = 0) or presence (Child-OIDP ≥ 1) of impact on quality of life. Results: The prevalence of TDI was 34.3%. Schoolchildren with untreated TDI experienced a greater impact on eating (P = 0.016) and smiling (P < 0.001) in comparison with those without TDI. No significant differences were found in the Child-OIDP score between schoolchildren with treated TDI and those without trauma. The unadjusted and adjusted results of the Poisson regression analysis of the Child-OIDP demonstrated that schoolchildren with untreated TDI were more likely to experience an impact on 'eating and enjoying food', 'smiling and showing teeth', and 'overall score'. Conclusions: Untreated TDI was associated with a negative impact on the quality of life of schoolchildren, whereas treated TDI and absence of TDI were not associated with impact on quality of life. © 2013 John Wiley & Sons A/S.

Objective The aim of the present population-based cross-sectional study was to evaluate the association between untreated dental caries, considering stages and activity, and the impact on OHRQoL among preschool children and their parents/caregivers. Methods A randomly selected sample of 451 Brazilian preschool children aged three to 5 years underwent a clinical oral examination for the assessment of dental caries using the ICDAS II criteria. Parents/caregivers were asked to answer two questionnaires: one on the OHRQoL of the children (ECOHIS) and another on the demographic and socioeconomic characteristics of the children and families. Statistical analysis involved descriptive statistics, the chi-square test, Mann-Whitney test and hierarchically adjusted Poisson regression models. Results The prevalence of early childhood caries was 51.2%. The majority of teeth with caries exhibited severe decay (60.6%). Untreated severe decay, such as active lesions within visible dentin (P < 0.001), extensive active and inactive cavity without pulp exposure or fistula (P < 0.001 and P = 0.001, respectively), extensive cavity with pulp exposure and absence of fistula (P = 0.003) and root remnant (P = 0.002), were associated with a negative impact on quality of life. Conclusion Active and inactive untreated severe carious lesions were associated with a negative impact on the quality of life of preschoolers and their parents/caregivers. © 2013 John Wiley & Sons A/S.

Background: To investigate the correlation between anti-hepatitis C virus (HCV) antibodies in saliva and detection of HCV RNA in saliva and salivary glands of patients with chronic hepatitis C. Methods: A total of 180 samples of saliva (131 non-stimulated and 49 stimulated) from 133 patients with chronic hepatitis C were tested by ELISA for presence of anti-HCV antibodies. Results were compared with the detection of HCV RNA in saliva and salivary glands samples. Pearson's chi-squared and Fisher's exact tests were performed for statistical analysis. Results: Anti-HCV antibodies could be detected in 47/180 (26.1%) saliva samples. In 11/47 (23.5%) of these, HCV RNA was also detected. From the 133/180 (73.9%) saliva samples with undetectable anti-HCV antibodies, 49/133 (36.8%) were positive for HCV RNA at least in one saliva sample. From the 64 patients from whom salivary gland samples were available, 17/64 (26.6%) had detectable anti-HCV antibodies in saliva, from which 2/17 (11.8%) also had HCV RNA in the salivary gland. From the 47/64 (73.4%) cases negative for anti-HCV antibodies in saliva, 10/47 (21.3%) were positive for HCV RNA in salivary gland. Conclusions: Taken together, our results suggest that there is no correlation between the presence of anti-HCV antibodies in saliva and the detection of HCV RNA in saliva and salivary glands in patients with chronic hepatitis C. Nevertheless, as there was a statistically significant difference between detection of anti-HCV antibodies and HCV RNA in stimulated saliva, our study points toward the need for new research on mechanisms of HCV shedding in saliva.© 2012 John Wiley & Sons A/S.

Aimed to evaluate the effect of silicon, acibenzolar-S-methyl (ASM) and cultivars of cotton plant on the behavior of A. gossypii. Were conducted non-preference trials with apterous aphid and with winged aphid, both with nine treatments arranged in a factorial scheme 3 (inductors: Silicon ASM and Control) x 3 (cultivars BRS Verde, BRS Rubi and Safira), with thirteen replications. The treatments were distributed in a factorial scheme 3 (cv. BRS Verde, BRS Safira and BRS Rubi) x 3 (silicon, ASM and control) with thirteen replicates. Silicic acid at the dosage equivalent to 3 t ha -1 and 0.2% ASM were tested. For the test with apterous aphid, after 14 days from the application of the inducers, leaf sections of each treatment were placed into Petri dishes forming an arena where 24 adults aphid were released. The number of adults and nymphs of the aphid was evaluated after 24; 48 and 72 hours after release. For the second test, after 14 days from the application of the inducers, winged aphids were released randomly on the plants grown in an acclimatized chamber. After 24; 48 and 72 hours from the release, the number of winged adults and of nymphs present on the plants was evaluated. From the results, the both cv. Verde and Rubi were less infested in relation to Safira and the application of silicon did not affect the preference of A. gossypii. However the product ASM proved viable and could contribute to the reduction of the colonization of the plants by aphids.

The presence of retained foreign bodies in the maxillofacial region as a consequence of penetrating injuries from knives is poorly documented in the scientific literature. This manuscript reports the case of a 30-year-old Caucasian with a knife blade lodged in the maxillofacial skeleton. Following clinical and radiographic exams, it was determined that the object had penetrated through the left nostril and nasal septum, in the direction of the right maxillary sinus, and remained impacted without causing injury to important anatomical structures. After systemic assessment and determination of the exact location of the knife blade, the object was removed in an outpatient setting under local anaesthesia. This manuscript aims to report a rare case of a transfacial penetrating injury involving a knife blade that was removed in an outpatient setting while also discussing the proper conduct and treatment options for similar cases in the context of a brief literature review.

In a previous study, we evaluated the influence of periodontal treatment and physiological parameters on the subjective perception of mastication using the Oral Impact on Daily Performance Questionnaire (OIDP). In this study, we investigated the influence of periodontal treatment on the objective measures of masticatory performance in the same study sample. Patients with chronic periodontitis (n = 28) were examined on two occasions with a 45-day interval. Electrical activity of the masticatory muscles and maximum bite force were determined. In addition, masticatory performance was assessed using silicone impression blocks as test material. The median particle size of the chewed blocks was determined employing a sieving method. The number of teeth and the probing depth were also recorded. The probing depth was significantly reduced following treatment (P < 0.001). The median particle size of the chewed material was also reduced, which indicates a significant improvement in masticatory performance after treatment (P < 0.001). Bite force and muscle activity were significantly correlated both before and after treatment (P < 0.05). There was a negative correlation between masticatory performance and number of teeth (P < 0.05); moreover, individuals with a lower number of teeth exhibited poorer masticatory performance (P = 0.01). Periodontal treatment had a positive influence on masticatory performance 45 days after conservative treatment.

In crowded dental arches, the permanent lateral incisors often erupt and resorb the mesial portion of the root of deciduous canines, causing their premature loss. Therefore, knowledge on clinical aspects related to etiologic factors is necessary to pediatric orthodontists and clinical dentists for diagnosis and treatment with regard to incisor crowding and adjustment. The aim of the present study was to describe a clinical case characterized by the unilateral loss of a lower deciduous canine, offering clinical considerations on this issue and discussing the various procedures implemented to prevent potential problems. A patient, 8 years of age, had the lower right deciduous canine prematurely lost, resulting in a deviation from the midline to the same side of the loss caused by the migration of the permanent incisors. The antimeric canine was removed and a fixed apparatus was attached to the lower arch associated to a spring to correct the midline. Next, a lip bumper device was employed to promote the vestibular conduction of the lower incisors to accommodate the permanent canines in the arch. Although early loss of deciduous canines occurs frequently, treatment possibilities are controversial and further studies on the subject are necessary Orthodontic evaluation should be always considered to minimize the need to extract permanent teeth and/or future orthodontic treatment.
