Background: Adolescents who rely on social aid networks tend to be more socially competent and enjoy higher levels of quality of life than those who interact only with their own limited groups of family and friends. In this light, the present study aimed to measure social capital and analyse its possible relation to adolescents’ quality of life. Methods: This is a cross-sectional analytical study with 363 adolescents from the Brazilian NGO. The instruments used included a short Portuguese version of the Integrated Questionnaire to Measure Social Capital (SC-QI) from the World Bank and its abbreviated Portuguese version from the World Health Organization Quality of Life Bref (WHOQoL-Bref) used to measure the quality of life. To measure social capital, the present study chose to use a segmentation analysis, along with the Two-Step Cluster method, applying Euclidian distance and the criteria of centroid aggregation. The Mann-Whitney test was used to compare the scores of WHOQoL-Bref domains among the clusters, at a significance level of 5%. Results: The segmentation analysis resulted in two clusters, with 160 (44.1%) adolescents classified as Low Social Capital (LSC) and 178 (49%) classified as High Social Capital (HSC). Participation in activities for the good of the community (p < 0.001), opinion regarding the differences between people in the community (p = 0.002), and number of community meetings (p < 0.001) constituted the decisive variables for determining the separation of the clusters. When quality of life among the newly formed clusters was compared, the highest average score in the HSC cluster was found in the Psychological Domain (75.4 ± 11.9), whereas in the LSC cluster, the highest average score was found in the Physical Domain (74.6 ± 12.6). Lower quality of life scores was found in the environmental domain for both the LSC clusters (51.3 ± 14.0) and the HSC clusters (54.7 ± 15.5). This difference proved to be statistically significant (p = 0.009). Conclusions: The results showed that adolescents with higher social capital also presented higher

Leles, Cláudio Rodrigues;Freire, Maria do Carmo Matias;
Journal of Applied Oral Science , 2004, DOI: 10.1590/S1678-77572004000200009
Abstract: a critical problem in the decision making process for dental prosthodontic treatment is the lack of reliable clinical parameters. this review discusses the limits of traditional normative treatment and presents guidelines for clinical decision making. there is a need to incorporate a sociodental approach to help determine patient's needs. adoption of the evidence-based clinical practice model is also needed to assure safe and effective clinical practice in prosthetic dentistry.
Patients' self-perceived impacts and prosthodontic needs at the time and after tooth loss
Teófilo, Linéia Tavares;Leles, Cláudio Rodrigues;
Brazilian Dental Journal , 2007, DOI: 10.1590/S0103-64402007000200001
Abstract: studies on self-perception have demonstrated that tooth loss is associated with esthetic, functional, psychological and social impacts for individuals. however, not all subjects seek treatment immediately after tooth loss, even when desire for replacement is strongly expressed. the aim of this study was to evaluate the perception of patients submitted to tooth extraction about factors associated with tooth loss and prosthodontic treatment, at the time and after extraction. a convenience sample of 211 consecutive patients were clinically evaluated and answered to a questionnaire about perceived impacts and prosthodontic treatment needs. data were collected at the time of extraction and after a 3-month time interval. perceived impacts were high (21 to 76% at the time and 35 to 87% after extraction). from 72.5% patients who expressed intention of immediate replacement of edentulous spaces, only 8.1% had actually been treated. financial limitation was considered the most important factor that restricted access to treatment. bivariate statistical analysis showed association between immediate dental replacement and anterior tooth loss (p=0.00) and extension of edentulous space (p=0.01). position of lost teeth was associated to perceived functional limitation (p=0.03). worsened appearance was associated to tooth loss in the maxillary arch (p=0.02), and desire of prosthodontic treatment was associated to the extension of edentulous space (p=0.05). perceived impacts were more frequent in women than men. it was concluded that although patients usually expressed prosthodontic treatment needs, clinical and financial issues are determinant factors for tooth replacement.

Leles, José Luiz Rodrigues;Santos, ênio José dos;Jorge, Fabrício David;Silva, Erica Tatiane da;Leles, Cláudio Rodrigues;
Journal of Applied Oral Science , 2010, DOI: 10.1590/S1678-77572010000100006
Abstract: background: maxillofacial injuries occur in a significant number of trauma patients. epidemiological assessments are essential to reaffirm patterns, identify new trends and develop clinical and research priorities for effective treatment and prevention of these injuries. objective: the aim of this study was to identify the epidemiological profile and risk factors associated with maxillofacial trauma treated at a referral emergency hospital for the public health system in the state capital of goiás, brazil. material and methods: a cross-sectional study was designed including 530 patients with maxillofacial trauma, 76% male, with a mean age of 25.5±15.0 years. data were collected between may 2003 and august 2004 over weekly shift-working periods. results: the main causes of trauma were traffic accidents (45.7%) and physical assaults (24.3%), and differences in etiological factors were identified according to gender (p<0.001). the distribution of patients according to age and etiology showed significant differences for traffic accidents (p<0.01), physical assaults (p<0.001), falls (p<0.001) and sport injuries (p<0.01). in the multinomial logistic regression analysis (r2 = 0.233; p<0.05), age was associated with injury in traffic accidents and falls (p<0.01), sports-related accidents were associated with males (p<0.05), and alcohol consumption with assaults and traffic accidents (p<0.001). facial soft tissue lesions were found in 98% of patients and facial fractures in 51%. conclusions: the significant association of maxillofacial trauma with young males and alcohol consumption reinforces the need for educational strategies and the development of policies for the prevention and reduction of associated damage in this specific risk group.

Education Research International , 2011, DOI: 10.1155/2011/107069
Abstract: The aim of the study was to explore treatment efficiency in an undergraduate comprehensive dental care program (CDCP). The study sample consisted of the records of 652 patients from the CDCP of the School of Dentistry, Federal University of Goias, Brazil, who were treated in the period from 2004 through 2009. A total of 45 clinical procedures performed by the students was listed and a panel of 19 judges, graded the perceived complexity of each procedure on a 11-point scale using an adaptation of the Thurstone method. Spearman's correlation, one-way Anova, Kaplan-Meier, and Cox regression were used to build a predictive model for time-to-event data—completion of treatment (CT). Treatment time for CT was correlated with complexity scores (=0.60; <0.001). The average estimated median months for CT was 23.0 (95%CI = 19.6–26.3) and was significantly different (<0.001) among complexity levels (low 13.0, intermediary 19.0, high 47.0). When low complexity was the reference category, estimated changes in risk for incomplete treatment were greater for intermediary (HR=0.54; 95%CI = 0.40–0.75) and high complexity cases (HR=0.32; 95%CI = 0.23–0.45). The results indicated that treatment complexity has a large influence on undergraduate CDCP efficiency and should be considered when planning organizational strategies for the clinical environment.

Abstract: after complete denture insertion, edentulous patients usually present transitory difficulties. this is one of the most critical stages of prosthetic treatment and it is strongly related to the prostheses acceptance. the aim of this study was to evaluate potential changes in the mandibular movement pattern related to insertion of the complete denture during the functional adaptation period. the kinesiograph instrument k6-i (myotronics research inc., seattle, wa) was used to evaluate eight edentulous patients that received conventional complete denture treatment. recordings of opening and closure movement limits, movement velocity, postural rest position, chewing cycle and limits of eccentric movements were performed. each patient was evaluated in four different stages: with the old dentures, immediately after insertion of the new dentures, and 30 days and 6 months after insertion of the dentures. the results showed that there were no remarkable changes in the mandibular motion patterns after insertion of the new dentures. it was suggested that the problems related to the process of utilization of new dentures are not strictly associated to the mandibular movement. therefore, functional adaptation after denture insertion is not directly related to functional changes, but to the quality of the dentures and to individual features.

Souza, Raphael Freitas de;Compagnoni, Marco Antonio;Leles, Cláudio Rodrigues;Sadalla, Karina Buainain de Freitas;
Journal of Applied Oral Science , 2005, DOI: 10.1590/S1678-77572005000400018
Abstract: the purpose of this study is to determine the association of speaking space of /s/ sound with vertical and horizontal overlaps for two subject groups. group i comprised 61 subjects with complete permanent dentition and group ii comprised 33 complete denture wearers. they had their mandibular movement determined by using an electromagnetic method. speaking space of /s/ was obtained from each subject as they were instructed to say the word 'seis' three times. the mean interocclusal distance during /s/ production was considered the speaking space of /s/. vertical and horizontal incisor overlaps were also measured. the mean value of speaking space of /s/ was 2.22 mm (± 1.38) for group i and 2.61 mm (± 1.53) for group ii. in group i, significant correlations were found between the speaking space of /s/ and vertical overlap (r=0.36, p<0.01), and between speaking space of /s/ and horizontal overlap (r=0.45, p<0.01). in group ii, no significant correlation was found between speaking space of /s/ and the overlaps. it was concluded that incisor overlap had a direct influence on the measure of speaking space of /s/ for dentate subjects, but this association was not present for complete denture wearers.

Abstract: the mucosa that covers the residual ridges of edentulous patients may present some distortion or displacement when occlusal loading is applied in complete dentures. this distortion and movement of the denture can result in acceleration of residual ridge resorption and loss of retention and stability. the aim of this study was to analyze the pattern of upper complete denture movement related to underlying mucosa displacement. a sample of 10 complete denture wearers was randomly selected, which had acceptable upper and lower dentures and normal volume and resilience of residual ridges. the kinesiographic instrument k6-i diagnostic system? was used to measure denture movements, according to the method proposed by maeda et al.7, 1984. denture movements were measured under the following experimental conditions: (a) 3 maximum voluntary clenching cycles and (b) unilateral chewing for 20 seconds. the results showed that under physiological load, oral mucosa distortion has two distinct phases: a fast initial displacement as load is applied and a slower and incomplete recovery when load is removed. intermittent loading such as chewing progressively reduces the magnitude of the denture displacement and the recovery of the mucosa is gradually more incomplete.
