Efeitos bioestimulantes do laser de baixa potência no processo de reparo

The wound healing process has always been an excellent subject for researchers. The use of low-power laser on wounds during the postoperative phase has increased the speed of the healing process. It has been implied that low power radiation affects cellular metabolic processes and promotes beneficial biological effects (analgesic, anti-inflammatory, and healing). Laser biostimulation appears to influence the behavior of the repair process. This paper aims at reviewing the most interesting aspects of the use of low-power laser in the tissue-repair process.

Impact of oral health conditions on the quality of life of preschool children and their families: a cross-sectional study.

BackgroundDental caries, traumatic dental injury (TDI) and malocclusion are common oral health conditions among preschool children and can have both physical and psychosocial consequences. Thus, it is important to measure the impact these on the oral health-related quality of life (OHRQoL) of children. The aim of the present study was to assess the impact of oral health conditions on the OHRQoL of preschool children and their families.MethodsA preschool-based, cross-sectional study was carried out with 843 preschool children in the city of Campina Grande, Brazil. Parents/caregivers answered the Brazilian Early Childhood Oral Health Impact Scale and a questionnaire addressing socio-demographic data as well as the parent’s/caregiver’s perceptions regarding their child’s health. Clinical exams were performed by three researchers who had undergone a calibration process for the diagnosis of dental caries, TDI and malocclusion (K = 0.83-0.85). Hierarchical Poisson regression was employed to determine the strength of associations between oral health conditions and OHRQoL (α = 5%). The multivariate model was run on three levels obeying a hierarchical approach from distal to proximal determinants: 1) socio-demographic data; 2) perceptions of health; and 3) oral health conditions.ResultsThe prevalence of impact from oral health conditions on OHRQoL was 32.1% among the children and 26.2% among the families. The following variables were significantly associated with a impact on OHRQoL among the children: birth order of child (PR = 1.430; 95% CI: 1.045-1.958), parent’s/caregiver’s perception of child’s oral health as poor (PR = 1.732; 95% CI: 1.399-2.145), cavitated lesions (PR = 2.596; 95% CI: 1.982-3.400) and TDI (PR = 1.413; 95% CI: 1.161-1.718). The following variables were significantly associated with a impact on OHRQoL among the families: parent’s/caregiver’s perception of child’s oral health as poor (PR = 2.116; 95% CI: 1.624-2.757), cavitated lesions (PR = 2.809; 95% CI: 2.009-3.926) and type of TDI (PR = 2.448; 95% CI: 1.288-4.653).ConclusionCavitated lesions and TDI exerted a impact on OHRQoL of the preschool children and their families. Parents’/caregivers’ perception of their child’s oral health as poor and the birth order of the child were predictors of a greater impact on OHRQoL.

Obesity and Dental Caries among Preschool Children in Brazil

AIM This study was aimed at verifying the relationship between childhood obesity and dental caries. METHOD A total of 2,651 preschool children were examined for this cross-sectional study in Recife, Pernambuco, Brazil; 1,338 of them attended public schools and 1,313 private schools. The clinical data and anthropometric measurements were obtained in line with WHO criteria. Pearson chi-square and Mann-Whitney tests were used, with a 5 % margin of error. RESULTS The prevalence of child obesity was 9 % (n=240). The highest prevalence was observed amongst children in private elementary schools (p<0.0001). The prevalence of dental caries was 19 % (n=504). The DMFT index was smaller in non-obese individuals (p=0.0267). The average value of dental caries, lost teeth and DMFT were significantly higher among children in public elementary schools than amongst those in private pre-schools (p<0.0001). CONCLUSION No relationship was found between dental caries and obesity. Suitable health policies should be adopted so as to minimise the high prevalence of dental caries among this population.

Perceived Impact of Dental Pain on the Quality of Life of Preschool Children and Their Families.

The aim of the present study was to evaluate the perceived impact of dental caries and dental pain on oral health-related quality of life (OHRQoL) among preschool children and their families. A cross-sectional study was conduct with 843 preschool children in Campina Grande, Brazil. Parents/caregivers answered a questionnaire on socio-demographic information, their child’s general/oral health and history of dental pain. The Brazilian version of the Early Childhood Oral Health Impact Scale was administered to determine the perceived impact of caries and dental pain on OHRQoL. The children underwent an oral examination. Logistic regression for complex sample was used to determine associations between the dependent and independent variables (OR: Odds ratio, α = 5%). The independents variables that had a p-value <0.20 in the bivariate analysis were selected for the multivariate model. The prevalence of dental caries and dental pain was 66.3% and 9.4%, respectively. Order of birth of the child, being the middle child (OR: 10.107, 95%CI: 2.008-50.869) and youngest child (OR: 3.276, 95%CI: 1.048-10.284) and dental pain (OR: 84.477, 95%CI: 33.076-215.759) were significant predictors of the perceived impact on OHRQOL for children. Poor perception of oral health was significant predictor of the perceived impact on OHRQOL for family (OR=7.397, 95%CI: 2.190-24.987). Dental caries was not associated with a perceived impact on the ORHQoL of either the children or their families. However, order of child birth and dental pain were indicators of impact of OHRQoL on preschool children and poor perception of oral health was indicators of impact on families.

Determinant Factors of Untreated Dental Caries and Lesion Activity in Preschool Children Using ICDAS

The aim of the present study was to investigate determinant factors associated with the presence of dental caries and lesion activity in preschool children. A population-based, cross-sectional study was carried out with 843 children of aged three to five years enrolled at public and private preschools in the city of Campina Grande, Brazil. A questionnaire addressing socio-demographic data and oral health care was self-administered by parents/caregivers. Three dentists previously calibrated examined the children for the diagnosis of dental caries and lesion activity using the International Caries Detection and Assessment System (ICDAS). Nutritional status was evaluated based on the body mass index. Logistic regression analysis for complex samples was performed (α = 5%). The prevalence of dental caries was 66.3%. Among the children with caries, 88.0% had active lesions. Dental caries was more prevalent in girls (OR = 1.53, 95%CI: 1.05–2.23), in children from families with a monthly household income ≤US

Prevalence and Associated Factors for the Development of Anterior Open Bite and Posterior Crossbite in the Primary Dentition

312.50 (OR = 2.38, 95%CI: 1.65–3.43) and those whose mothers had up to eight years of schooling (OR = 1.55, 95%CI: 1.07–2.23). Lesion activity was significantly associated with mother’s schooling ≤ 8 years (OR = 2.15, 95%CI: 1.15–4.00). The prevalence rates of dental caries and lesion activity were high and mainly associated with a lower socioeconomic status and mother’s schooling.

Predisposing Factors for Traumatic Dental Injury in Primary Teeth and Seeking of Post-trauma Care

The aim of the study was to verify the prevalence of anterior open bite (AOB) and posterior cross-bite (PC) in the primary dentition and the association with sociodemographic factors, presence and duration of nutritive and non-nutritive habits. A cross-sectional study was carried out with 732 preschoolers in Campina Grande, PB, Brazil. Clinical exams were performed by three calibrated examiners (Kappa: 0.85-0.90). A questionnaire addressing sociodemographic data as well as nutritive and non-nutritive sucking habits was administered to parents/caregivers. Data analysis involved descriptive statistics and Poisson regression analysis (α=5%). The prevalence of AOB and PC was 21.0% and 11.6%, respectively. AOB was significantly associated with the three-year-old age group (PR: 1.37; 95%CI: 1.24-1.52), enrollment in public school (PR: 1.09; 95%CI: 1.01-1.17) and duration of pacifier sucking ≥ 36 months (PR: 1.41; 95%CI: 1.30-1.53). PC was associated with pacifier use (PR: 1.11; 95%CI: 1.05-1.17) and duration of breastfeeding <12 months (PR: 1.05; 95%CI: 1.00-1.10). Socioeconomic factors appear not to be related to AOB or PC in the primary dentition, except type of preschool. Breastfeeding should be encouraged for longer periods and the use of pacifier beyond 3 years of age represents a predisposing factor for both types of malocclusion, especially AOB.

Dental trauma among Brazilian schoolchildren: prevalence, treatment and associated factors

The aim of the present study was to investigate predisposing factors for traumatic dental injury (TDI) in the primary dentition and seeking of dental care after the occurrence of TDI. A randomized population-based cross-sectional study was carried out with 814 children aged 3 to 5 years enrolled at public and private preschools in the city of Campina Grande, PB, Brazil. Parents were asked to fill out a questionnaire on demographic data and the childs history of TDI. TDI was evaluated by clinical examinations performed by three previously calibrated dentists (Kappa: 0.85 to 0.90). Bivariate and multivariate Poisson regression models were constructed for TDI and the parent-reported search for dental care (α=0.05). The prevalence of TDI was 34.6%. The most common type of TDI was enamel fracture (55.0%). The central incisors were the most frequently affected teeth (87.5%). Predictors for TDI in the primary dentition were household income >U

Smoking among undergraduate students in the area of health

312.50 (PR: 1.355; 95% CI: 1.050-1.724) and overjet >2 mm (PR: 1.539; 95% CI: 1.219-1.942). The predictor for seeking dental care following TDI was parents age >30 years (PR: 1.753; 95% CI: 1.039-2.960). Household income and overjet were associated with TDI. Among children having suffered TDI, parents age is a crucial determinant for seeking dental care.

Impact of Traumatic Dental Injury on the Quality of Life of Brazilian Preschool Children

AIM: To assess the prevalence of traumatic dental injury (TDI), as well as associated factors, behaviour of affected schoolchildren and normative treatment needs. METHODS: The present cross-sectional study involved 590 children aged 7–14 years at state schools in Campina Grande, Brazil. The O’Brien classification [1994] was used for the diagnosis of TDI and the body mass index (BMI) was used as an indicator of overweight/obesity. Clinical tests were carried out by two duly calibrated examiners (intra-observer and inter-observer agreement: 0.87 and 0.90, respectively). The Chi-square test was used (5% level of significance) to determine whether TDI was associated with age, gender, ethnicity, overweight/obesity, lip seal and overjet. Backward stepwise multivariate regression analysis was performed. Normative treatment needs were determined based on the criteria of the International Association of Dental Traumatology (IADT). When the absence of treatment was detected, each child/adolescent was asked about the reason for non-treatment. RESULTS: The prevalence of TDI was 12.7%. The most common type of trauma was enamel fracture (67.0%), followed by enameldentine fracture (25.3%). TDI was 4.9-fold greater (95% CI: 1.6-14.4) among children aged 13 and 14 years, 1.9-fold greater (95% CI: 1.1-3.2) among males and 2.6-fold greater (95% CI: 1.2-5.4) among those with inadequate lip seal. The majority of schoolchildren did not undergo treatment (82.6%) due to a belief that it was unnecessary (53.2%). The normative clinical evaluation revealed that adhesive restoration was the most common form of treatment (84.0%). CONCLUSION: The prevalence of TDI was low. Age, gender and inadequate lip seal were associated with dental trauma. A significant number of schoolchildren did not receive treatment for dental trauma.
