Avaliação in vitro do potencial erosivo de bebidas isotônicas

A sports drink is a beverage made to rehydrate, as well as replace electrolytes, carbohydrates, and other nutrients. The objective of this in vitro study was to evaluate the endogenous pH, total titratable acidity and total soluble solids content (TSSC) of nine sports drinks. pH analysis was performed by potentiometry and buffering capacity was assessed by dilution of each substance. Increments of 0.1 N KOH were titrated until neutrality was reached. TSSC readings were performed by Brix refractometry using the Abbe refractometer. pH values ranged from 2.03 (Gatorade Tangerina®) to 2.93 (Marathon Limao®) and all sports drinks showed pH below the critical value of 5.5. The titratable acidity values ranged from 0.106 (Marathon Limao®) to 0.32 (Gatorade Tangerina®). Gatorade Tangerina® presented the lowest TSSC content (6.33%) and Marathon Guarana e Acai® presented the highest TSSC content (12.50%). Statistically significant differences were observed between temperatures for pH (G3, G4, G5, G6 and G8), TSSC (G2, G3, G6 and G9) and TA (G2, G3 and G5). When groups 1 and 3 were compared (Marathon Guarana Acai versus Gatorate Guarana Acai), statistically significant difference concerning pH at room temperature, concerning TSSC at room and ± 9oC temperatures and concerning TA at room temperature was seen. The sports drinks evaluated have a high erosive potential to dental hard tissues, as they present low pH. Regarding temperature, it is recommended to intake these beverages chilled.

Dental Caries Experience and Use of Dental Services among Brazilian Prisoners

This ross-sectional study involving 127 male prisoners evaluates the use of dental services and dental caries among Brazilian inmates. Data were collected by interview and clinical examination. Sociodemographic and sentencing information as well as use of dental services, self-reported dental morbidity, self-perception, and oral health impacts were investigated. The mean DMFT index value was 19.72. Of the components, the decayed component showed the highest mean value (11.06 ± 5.37). Statistically significant association was found between DMFTs with values from 22 to 32 and oral health satisfaction (p = 0.002), difficulty speaking (p = 0.024), shame of talking (p = 0.004) and smiling (p < 0.001). Regarding the use of dental services, 80% had their last dental appointment less than one year ago, with most visits occurring in prison (80%), with restorative treatment (32%), followed by dental pain (26.4%), being the main reasons for such appointments. Most prisoners used dental services provided by the prison. Although restorative treatment has been the main reason for the use of dental services, “decayed” and “missing” components contributed to the high mean DMFT index.

Locked mouths: Tooth loss in a women's prison in northeastern Brazil.

Background. Prisoners, in general, exhibit unsatisfactory oral conditions, especially with regard to the large number of missing teeth and with untreated caries. The aim of this study was to assess tooth loss, use of and need for prosthetic rehabilitation, and use of dental services among inmates. A cross-sectional study involving 65 inmates was developed at the Regional Womens Prison of Campina Grande, Brazil. Data regarding sociodemographic and sentencing profile, use of dental services, dental morbidity, and self-perceived oral health impacts were investigated. Chi-square, Pearson, and Kruskal-Wallis (P < 0.05) statistical tests were used. The mean tooth loss was 11.3 teeth. Significant association between tooth loss and oral health satisfaction (P = 0.049), self-perceived need for dental prosthesis (P < 0.001), uncomfortable teeth brushing (P = 0.005), difficult speaking (P = 0.002), and difficulty in performing routine tasks (P = 0.025) was observed. It was observed that 29.2% of inmates were using some type of prosthesis, all deemed unsuitable for use, and 78.5% of inmates needed prosthetic rehabilitation. The oral health condition of the population studied was found to be poor, and prisoners showed significant tooth loss and need for dentures, with the aggravation of having tooth extraction as the major reason for seeking dental care.

Loss on drying, calcium concentration and pH of fluoride dentifrices

Introduction: Fluoride dentifrices containing calcium carbonate have advantages such as control of dental plaque and progression of dental caries, also contributing to oral hygiene, represent most dentifrices marketed in Brazil. Aim: To evaluate the physicochemical properties of seven fluoride dentifrices containing calcium carbonate in relation to hydrogen potential (pH), loss on drying and calcium concentration. Materials and Methods: Data collection was performed using the potentiometric method for pH ranges, gravimetric analysis for loss on drying and atomic absorption spectrometry for the concentration of calcium ions. All tests were performed in triplicate and the analysis was performed entirely at random according to one-way analysis of variance at 5% significance level. Results: The pH values were alkaline and ranged from 8.67 (Oral-B 123®) to 10.03 (Colgate Máxima Proteção Anticáries®). The results of loss on drying ranged from 33.81% (Oral-B 123®) to 61.13% (Close Up®), with significant differences between brands tested. In relation to the calcium content, the highest and lowest concentrations were found in dentifrices Even® (155.55 g/kg) and Colgate Ultra Branco® (129 g/kg), respectively, with significant difference (P < 0.05). Conclusion: Fluoride dentifrices analyzed showed alkaline pH and high levels of loss on drying and calcium concentration. However, these physicochemical characteristics differed according to the different brands tested.

Head and Maxillofacial Injuries in Child and Adolescent Victims of Automotive Accidents

Background. Victims of motor vehicle accidents may suffer multiple lesions, including maxillofacial injuries. The aim of this study was to evaluate the prevalence and factors associated with head, facial, and maxillofacial injuries in child and adolescent victims of automobile accidents. A cross-sectional study was carried out with analysis of forensic medical reports from the Legal Medical Institute of Campina Grande, Brazil, between January 2008 and December 2011. Descriptive and inferential statistical analysis was conducted using the chi-square test (α = 0.05). From 1613 medical reports analyzed, the sample is composed 232 (14.4%) reports referring to child and adolescent victims of automobile accidents aged 0–19 years of both sexes. Victims were mostly adolescents aged from 15 to 19 years (64.2%), males (73.7%), and motorcyclists (51.3%). More than half of the victims had single lesions (54.3%) located in the head (20.7%) and face (21.6%). Head injuries occurred more frequently in children aged 0–4 years (53.8%, PR = 5.065, 95% CI = 1.617–5.870) and pedestrians (30.4%, PR = 2.039, 95% CI = 1.024–4.061), while facial and maxillofacial injuries occurred in higher proportion among females (31.1%, PR = 0.489, 95% CI = 0.251–0.954). Our findings suggest that accidents involving motorcyclists are the most prevalent, affecting male adolescents aged from 15 to 19 years, resulting in a high frequency of injuries in the head and face regions.

Evaluation of total soluble solids content (TSSC) and endogenous pH in antimicrobials of pediatric use

BACKGROUND The use of liquid pharmaceutical preparations is a daily occurrence for some children. Evidences show a significant relation between the intake of oral sucrose based medicines and an increase incidence in dental caries. AIM This in vitro experimental study evaluated the Total Soluble Solids Content (TSSC) by means of Brix scale refractometry and the endogenous pH of antimicrobials of pediatric use presented as oral suspensions. MATERIALS AND METHODS Nine medications (6 chemotherapics and 3 antibiotics) were evaluated by random experiment with 3 repetitions for each sample. The analysis of TSSC readings were performed by Brix refractometry using the Abbé refractometer, and the pH values were determined by potentiometry. RESULTS The mean TSS contents ranged from 11.73 (Keflaxina) to 63.83 (Azitromed). The minimum and maximum mean pH values were 4.12 (Keflaxina) and 10.97 (Zitroneo), respectively. CONCLUSIONS The chemotherapic antimicrobials evaluated in this study presented the highest TSSC means, while the antibiotics showed pHs below the values considered as critical, which may contribute to the development of caries lesions in case of inadequate administration of these medications to children.

EFEITO DOS SUCOS DE FRUTAS INDUSTRIALIZADOS NA MICRODUREZA DO ESMALTE DENTAL PERMANENTE

Objective: To analyze in vitro the endogenous pH and the effect of industrialized fruit juices on the microhardness of permanent tooth enamel. Material and Method: Sample was composed of 10 beverages from two commercial brands and different flavors. Experimental groups were formed by selecting the beverages with lower and higher pHs according to the brands. Twenty-five specimens were prepared from human third molars and randomly assigned into five groups: G1: Ades Uva®, G2: Ades Morango®, G3: Kapo Uva®, G4: Kapo Laranja® and G5: Control (distilled water). Vickers microhardness was analyzed before (T1) and after (T2) the demineralization-remineralization cycles by applying a 100 g load during 15 seconds. The specimens were immersed in the juices during 1 minute, followed by 3 minutes in artificial saliva. Wilcoxon test was used for statistical analysis with 5%significance level and 95% confidence level. Results: All beverages presented pH values below the critical value of 5.5 for enamel demineralization, varying from 3.53 to 3.93. Microhardness analysis showed statistically significant difference (p=0.04) in all experimental groups, the largest reduction was observed in G1 (190.67). Conclusion: All beverages promoted a significant decrease in permanent enamel microhardness, being considered as potentially erosive under the conditions of this study. DESCRIPTORS Hardness Tests.
