Comparative analysis of Scale of oral health outcomes for 5-year-old children (SOHO-5) and Early Childhood Oral Health Impact Scale instruments

Objective: The aim of the present study was compare SOHO-5 and ECOHIS instruments for evaluation of dental caries impact on 5-year-old children quality of life. The sample was comprised by 121 children/parents randomly selected in Diamantina-MG. Children were submitted to oral examination for caries assessment. Parents answered the ECOHIS and SOHO - 5p and children answered the children's version of the SOHO-5c. The comparative analysis was performed between ECOHIS x SOHO-5p, SOHO-5c x SOHO-5p and ECOHIS x SOHO-5c for each item of the instruments (pain, difficulty eating, talking, playing, sleeping, avoid smiling). Each instrument was associated with caries. Statistical analyzes involved Kruskal -Wallis test, Mann -Whitney test and Spearman correlation and the analysis of the area under the receiver operating curve. There was significant correlation between SOHO-5p and ECOHIS (p<0.001). No significant correlation was observed between SOHO-5c x SOHO-5p and SOHO-5c x ECOHIS (p>0.05). Significant association was found between the instruments ECOHIS and SOHO-5p with caries (p<0.05). No association was found between the SOHO-5c and caries (p>0.05). The analysis of the area under the ROC curve showed that SOHO-5c, SOHO-5p and the ECOHIS discriminate children with and without caries with a precision of 52%, 68% and 72% respectively. ECOHIS and SOHO-5p were similar to each other and were associated with caries. The account of the children was different from parents’ reports and was not able to discriminate between children with and without caries.

Assessment of Oral Health Care in Children with Diabetes Mellitus Type 1

Objective: This study evaluated the oral health care offered to children with diabetes mellitus type 1 (DM1) in the primary dentition. For that, it was selected at the Ambulatory of Diabetes from IPPMG/UFRJ children with DM1 who were in the primary dentition. The guardians were interviewed about oral hygiene, diet habits and dental treatment offered to the children. Oral examination was performed to determine the dfm-t index. A total of 23 children aging between 2 and 6 (3.83±1.11) years old composed the sample. In spite of 87% of the guardians have affirmed that the children’s oral hygiene is performed and 61% have been oriented by the doctor to search for dental care, 40% of the children has never been to dentist. From those who have visited the dentist, tooth pain and presence of dental cavities were the most common reasons to look for treatment. The restorative treatment was the dental procedure performed in the major of the children, reflecting on the dmf-t which varied from 3 to 20 (11±5.8). Even with the possibility of free dental treatment next to place the children have appointments regularly to the DM1 treatment, 40% of the guardians did not accept the dental treatment offered. The oral health influences positively the general health of children with DM1 but little attention has been given to promotion of oral health. It is necessary greater elucidation to the guardians about the importance of oral care to promote oral health and improve the quality of life of these children.

Performance of methods for detection of proximal caries lesions in primary molars - In vivo.

Objective: The aim of this clinical study was evaluate the performance of the visual method coded with the Nyvad criteria, radiographic examination (BW) and laser induced fluorescence DIAGNOdent Pen in detection of approximal caries lesions in primary molars. Forty-five children aged between 5 and 9 years who had primary molars with signs suggestive of the presence of caries or sound. The surfaces (n=59) were evaluated clinically and coded according to Nyvad criteria, and DDPen. The radiographic examination was performed only in those teeth scored with Nyvad criteria 2, 3, 5 or 6. Caries active and/or discontinued surface were restored, and the lesions’s depth after cavity preparation was used for validation. Sensitivity, specificity, accuracy and area under the ROC curve were calculated for each method, considering lesions in enamel and dentin ( D1 ) and only dentin lesions ( D2 ). Visual examination with the Nyvad criteria showed the highest specificity (0.95 in D1 and D2 in 0.93 ), accuracy ( 0.94 in D1 and D2 ), and area under the ROC curve ( 0.90 and 0.95 in D1 to D2 ), while DDPen showed the highest sensitivity ( 0.97 and 0.96 in D1 to D2). Although the performance of radiographic examination and DDpen have been good, the use of visual examination with NYVAD criteria was sufficient for the diagnosis of interproximal caries lesions in primary molars.

Effect of nanosized sodium trimetaphosphate added to low-fluoride dentifrices on enamel demineralization in vitro

Objective:To assess the effect of the concentration and particle size of sodium trimetaphosphate (TMP) on enamel demineralization when associated to low-fluoride dentifrices in vitro. Methodology: Bovine enamel blocks (4x4 mm) were analyzed by surface hardness (SH) and randomly divided into 12 groups (n=12/group) according to the dentifrices tested: Placebo (P), 500 µg F/g (500), 500 µg F/g associated to TMP at concentrations of 0.25, 0.5 and 3.0% with particles of conventional size (TMPc), or crushed in a ball mill for 24h (TMP24) or 48h (TMP48), besides a positive control (1,100 µg F/g). Blocks were submitted to 5 pH cycles (37 ºC) and treated twice/day (1 min) with slurries of the above-mentioned dentifrices. After the determination of final SH, the percentage of SH loss (%SHL) was calculated and data were submitted to ANOVA and Student-Newman-Keuls’ test (p<0.05). Results: A dose-response relationship was observed between %SHL and fluoride concentration in the dentifrices without TMP. However, the lowest values of %SHL were observed for 500/TMPc 3.0%, 500/TMP24 0.5% and 500/TMP 48 0.25%, without significant differences among them. Conclusions: The supplementation of dentifrices containing 500 µg F/g with TMP leads to a more effective reduction of %SHL when compared with a 1,100 µg F/g dentifrice.

In situ effect of Recaldent® containing chewing gum at different stages of human enamel erosion

Objective: This study evaluated the in situ effect of an chewing gum containing Recaldent® in different stages of dental erosion. Methods: Studied groups: GWR Trident Total® (with Recaldent®) GNR Trident Fresh® (no Recaldent®) and GC control (no gum). In the 1st step 72 human enamel blocks were selected by the hardness and were eroded in vitro (Coke®, 3 min - hardness evaluation). Twelve volunteers wore intraoral palatal devices for 24h in 3 crossover phases. In GWR and GNR volunteers chewed the gum for 30 minutes, 4 times in 24h. The hardness was assessed after 2 and 24h to calculate the percentage of surface hardness recovery. In the 2nd step (3 crossover phases of 7 days) 48 healthy blocks were randomized between groups and eight volunteers wore palatal devices which were immersed in 150ml of Coke® for 5 min, followed by a chewing gum for 30 min in GWR and GNR, 4x/day. Enamel alterations were measured by profilometry and analyzed by ANOVA/Tukey. Results: In the 1st step GWR (2h/50.0%; 24h/95.9%) showed higher hardness recovery compared to GNR (2h/30.0%; 24h/71.1%) and GC (2h/15.7%; 24h/40.9%) (p<0.05). In the 2nd step GWR (5.2 ± 2.8 µm) and CNR (3.8 ± 1.5 µm) significantly reduced tooth wear compared to GC (6.8 ± 3.5 µm), with no differences between the chewing gums (p>0.05). Conclusions: Recaldent® chewing gum increases remineralization of erosive lesions, but it is not able to enhance enamel protection against the erosive challenge.

Integration of Pediatric Dentistry and Orthodontics in Dentistry courses in Brazil

Objective: The present study aimed to diagnose the existence or not of integration between Orthodontics and Pediatric Dentistry in the 203 undergraduate courses in dentistry throughout Brazil, as well as the opinion and importance given by the professors and coordinators concerning the integration of the two disciplines, by means of a semi-structured questionnaire sent by both email and Survey Monkey. The response rate was of 30.54% in relation to the total number of undergraduate courses. The dentistry disciplines were integrated in 75.8% of the undergraduate courses, whether at public or private universities, and were offered mostly during the seventh and eighth periods of the course. This study showed that 80.6% of the surveyed individuals considered the integration possible and advantageous for the students’ education, while 95.2% of the surveyed individuals considered this integration to be important at children’s dental clinics; 47.05% of the surveyed individuals considered the major hindrance to integration to be related to the professors, while 27.45% considered this hindrance to be related to the institutions themselves; 86.67% of the institutions from the Southeast region of Brazil reported no integration between the disciplines. This finding was statistically significant when compared to integrated education in the other surveyed regions throughout Brazil.

Crescer Sorrindo/UERJ Project: integrating teaching, research and extension for 12 years

Abstract: Children can be affected by various dental problems such as dental caries, malocclusion and dental trauma. These dental problems can have a negative impact on children's lives and on their families’. For that reason, it is important to prevent them. Nevertheless, when they occur, they need to be promptly addressed in order to limit impairment on children´s quality of life. “CrescerSorrindo” project is an excellent opportunity for integrating theory and practice within pediatric dentistry. Due to its multidisciplinary focus, the project enables students and teachers to obtain a holistic view of the pediatric patient. “CrescerSorrindo” has been developed by the School of Dentistry/UERJ, at Piquet Carneiro Polyclinic, since 2001. The aim of the project is to promote the oral health of children up to 11 years of age through educational, preventive and restorative activities and to emphasize dental care for preschoolers. In 12 years, approximately 530 preschoolers have received dental care and more than 750 undergraduate and 150 graduate pediatric dentistry students have been involved. In addition, the project carries out scientific research in the field of children's oral health. Thus, the “CrescerSorrindo” project has been promoting children´s oral health, for the last 12 years, by integrating teaching, research and extension.

Promoting oral health in early childhood: age of joining the preventive program and behavioral aspects

Objective: This cross-sectional study was to analyze the level of interference of age when joining a dental care program in children from 0 to 48 months, who attended a dental care preventive government program in the State of São Paulo, Brazil, named ‘Dentistry for babies’ and the behavioral aspects about the children dental caries experience. A sample of 465 children were assigned into three groups: Babies whose mothers joined the program when still pregnant (n=50); Babies that joined the program during the first year of life (n=230); and Children that joined the program between 13 and 18 months (n=185). The Chi-Square and Kruskal-Walis tests (IC95%) assessed the relationship between the variables. It was observed that there was an association between group and dental caries (p<0.001), being the smaller prevalence for G0 and G1. Similarly, it was found association between the children’s age when joining the program with assiduity, cariogenic diet, oral night hygiene, duration of night feeding and parents’ educational level, children’s behavior through out the treatment, at home or at the office (p<0.001). Low socio-economic background (p>0.05) and day oral hygiene (p=0.214) were common variables in the groups with 99% of occurrence. Assiduity, night oral hygiene presence and parents’ level of education variables were protection factors for dental caries. Cariogenic diet and night feeding were determinant factors for dental caries. It was concluded that in order to promote children's oral health it is essential that children join the program earlier in life, assiduity and the children and parents’ positive behavior.

Pulpal response after using the low-level laser therapy on pulpotomy of human primary teeth

Objective: The aim of this study was to evaluate through clinical, radiographic and histological analyses the effects of LLLT on pulpal response of human primary teeth after pulpotomy. Twenty mandibular primary molars of children aged between 6 and 9 years were selected. The teeth were randomly divided into the following groups: Buckley’s Formocresol (diluted 1:5) (GI), Calcium Hydroxide (GII), LLLT + Zinc Oxide and (GIII), and Low-Level Laser therapy + Calcium Hydroxide (GIV), and treated by the pulpotomy technique. The clinical and radiographic evaluations were performed at 3 and 6 post-operative months. The teeth in the normal exfoliation period were extracted and processed for histological analysis and assessed through a score system. The clinical and radiographic results did not show statistically significant difference among groups (p>0.05). The statistical analysis of the histological assessment revealed statistically significant difference for pulpal inflammation, with the least degree of pulpal inflammation for group GIV. The group GII showed a higher rate of formation of mineralized tissue barrier, odontoblastic layer and dense collagen fibers. The group GI showed higher incidence of internal resorption. The results obtained indicated that the group GIV showed more satisfactory effects compared to other groups. Therefore, it is suggested that Low-Level Laser therapy with Calcium Hydroxide can be considered as an alternative technique for the pulpotomy of human primary teeth.

Bottle feeding and malocclusion in permanent dentition: systematic review and meta-analysis

Objective: To search for scientific evidence on the association between a history of breastfeeding compared to bottle feeding and risk of malocclusion in the permanent dentition. Methods: An electronic search was performed in seven databases with no restrictions regarding language or year of publication. Data were extracted on type of feeding habits (breastfeeding vs. bottle feeding) and duration of breastfeeding (< 6 months vs. ≥ 6 months). Relative risk measures and confidence intervals were described. Results: The systematic review included four studies (3 cross-sectional and 1 case-control). When malocclusion was evaluated using clinical data, bottle feeding was associated to increased mean protrusion of the maxillary and mandibular incisors as well as mean inclination of the maxillary incisors (OR: 1.464; 95% CI: 1.091-1.965). However, facial profile was not associated with the duration of breast feeding (OR: 0.885; 95% CI: 0.462-1.695). However, there were few studies and substantial heterogeneity among them. Conclusions: The scientific evidence suggests a weak association between bottle feeding and malocclusion in the permanent dentition. More prospective cohort studies are needed to confirm the evidence.

Marginal adaptation between glass fiber post and primary root dentin after 6 month degradation

Objective: The aim of this study was to evaluate the influence of filling materials andcleaning agents in marginal adaptation between glass fiber post and root canaldentin after 6 month degradation. Roots of primary bovine teeth wereendodontically treated and assigned into groups: Control (no material - C);Calen® + Zinc Oxide (CZO); Vitapex® (V); Calcipex II® (CP). After 7 days, fillingmaterials were removed and the roots were subdivided according the groups(n=10): No cleaning (NC); 70% Ethanol (E); Tergenform® (T). Glass fiber posts were luted using resin cement RelyXTMARC after acid etching, rinsing and application of adhesive system. Specimens were sectioned (±1 mm) and water storage for 6 month. After this period, they were polished and replicas were made. Images obtained by scanning electron microscopy were measured usingthe software Image J 1.45 to calculate the gap formation percentage (%G). Thedata were submitted to two-way ANOVA and Tukey’s test (α=5%). Interaction was not observed between the studied factors (p<0.05). Significant difference was observed for filling materials (p<0.01) and cleaning agents (p<0.05). COZ showed the lowest %G (41.90±21.45), significantly different from C(62.23±19.59). E showed %G (60.04±26.71) significantly different from T(46.84±22.77). It could be concluded that filling materials and cleaning agents influenced the marginal adaptation of glass fiber post to root dentin after 6 month degradation.

Bond strenght of hight-viscosity glass ionomer cement with addition of chlorhexidine diacetate according to substrate and time

Objective: This study evaluated the long-term influence of the addition of chlorhexidinediacetate (CHX) at different concentrations to a high-viscosity GIC on its adhesion to sound and caries-affected dentin. Sixty third molars were divided into 6 groups (n = 10) according to the condition of the substrate (sound and caries-affected dentine) and concentration of CHX added to the GIC (GIC + CHX 1% and 2% CHX), and GIC without CHX was used as control. Dentin flat surfaces were produced and half of them was subjected to artificial induction of caries. In each dentin surface of two specimens of the same material (1 mm in diameter and 1 mm in height) was made. They were kept at 37 °C with 100% humidity for 24 hours or immersed in distilled water for 6 months and tested for microshear. Bond strength data were submitted to ANOVA and Tukey’s test (α= 0.05). In sound dentin, GIC and GIC + CHX 1 % bond strength was statistically similar and higher than the GIC + CHX 2 % and there was no significant difference between immediate and six months analysis. In caries-affected dentin, GIC and GIC + CHX 1% showed bond strength statistically superior to GIC + CHX 2% in the immediate analysis. At six months analysis there was no difference between the groups, and GIC + CHX 2% was the only group in which bond strength didn’t reduce. The addition of CHX at 2% decreased GIC/dentin bond strenght, but was able to prevent bond degradation after six months.

Association between iron deficiency anaemia and severe early childhood caries - a case report

Objective: The aim of this study was to present a clinical case of a 3 years and 10 months old patient with severe anemia associated with severe early childhood caries. The patient had low hemoglobin levels (7.70 g / dl), ferritin (10.5 ng / dl) and serum iron (16 mg / dl), low hematocrit (25.9 %), and impaired growth and delayed neuro-psycho-motor development. He was admitted to the University Hospital of the Federal University of Santa Catarina, which received blood transfusion, antibiotics and iron supplements. It was performed the extraction of all 20 root fragments on 4 different days, under intravenous sedation with a combination of midazolam and ketamine. The discharge from the hospital occurred after 20 days of hospitalization, when hemoglobin levels (10.80 g / dl), ferritin (44.5 ng / dl) and serum iron (30 mg / dl) were normal and the hematocrit equal to 34.2%. Treatment of severe early childhood caries should occur as soon as possible, because the consequences of this disease can affect significantly the overall health of the patient.
