RESUMO
PURPOSE: The study aimed to evaluate the possible preventive effect of two concentrations (3 and 5% w/w) of Eugenia jambolana (EJ) extract against 5-FU-induced mucositis. METHOD: Sixteen adult rats were separated into four groups: two control and two preventive groups. Animals in Groups 1, 2, and 3 were injected intraperitoneally with 60 mg/kg/day of 5-FU on Day 1 followed by 150 mg/kg/day on Day 5. The rats in Group 4 (negative control) were given physiological saline at the same times and doses. Furthermore, on the fifth day of the study, the cheek and sublingual mucosa were irritated by external superficial scratches using the tip of an 18-G needle, followed by the application 15 µL of 20% acetic acid, after which 3 and 5% EJ w/w gels were applied topically for animals in Groups 2 and 3, respectively. RESULTS: The weight and the mucositis scores were recorded. Antioxidant and anti-inflammatory markers and biochemical tests were analyzed. Significant differences were found between the study groups in weight loss, clinical mucositis scores, mortality rates, and antioxidant and anti-inflammatory parameters. CONCLUSION: The preventive effect of 3% gel was significant, with no mortality rate, making it an option for preventive strategies.

Background. The chronic recommendation of pediatric drugs could exhibit erosive and cariogenic problems. Objective. To evaluate the effects of different pediatric drugs on the color stability of various restorative materials. Methods. Five specimens (1 mm × 3 mm) were prepared and immersed in ten different pediatric drugs and agitated every 8 hours daily for 2 min up to 1 week. Between immersion periods, the samples were stored in artificial saliva. After 1-week period, ΔEâ values were calculated. Two-way ANOVA and Fisher's LSD test were used for statistical analysis at a level of p < 0.05. Results. ΔEâ values were only significantly influenced by restorative material factor (p < 0.001) and varied in the range of 2.08 and 6.55 units for all drugs/restorative materials. The highest ΔEâ was found in Ferrosanol B-composite (6.55 ± 1.38) and the lowest one was found in Dolven-glass ionomer (2.08 ± 0.40) pairwise. The most prominent ΔEâ value elevations were obtained in composite material compared to the compomer and/or glass ionomers in Macrol, Ferrosanol B, and Ventolin (p < 0.001; for all) and also for other drugs (p < 0.05). Dolven exhibited significantly higher values compared to Augmentin (p = 0.021), Macrol (p = 0.018), and Ventolin (p = 0.013) in compomer group. Conclusion. The clinically perceptible color changes for tested composite/pediatric drug pairwise can be more problematic than compomer and glass ionomers in pediatric dentistry.

A selection of commercially available products containing stannous fluoride (SnF2 )/sodium fluoride (NaF), SnF2 /amorphous calcium phosphate (ACP), SnF2 /NaF/ACP, tin (Sn)/fluorine (F)/chitosan were compared with phytosphingosine (PHS) with respect to their anti-erosive properties in vitro. One-hundred and twenty bovine enamel specimens were immersed in the respective product slurries for 2 min, twice daily. The formulations were diluted with either remineralization solution or artificial saliva. After each treatment, an erosive challenge was performed for 10 min, twice daily, using citric acid, pH 3.4. The specimens were stored in remineralization solution or artificial saliva until the next treatment-erosion challenge. After 10 d, tissue loss was determined using profilometry. Enamel softening was determined through surface microhardness measurements. Tissue-loss values (measured in µm and expressed as mean ± SD) for PHS, SnF2 /NaF, SnF2 /ACP, SnF2 /ACP/NaF, and Sn/F/chitosan treatment groups and for the negative-control group, were, respectively, 35.6 ± 2.8, 15.8 ± 1.8, 22.1 ± 2.0, 22.9 ± 1.8, 16.2 ± 1.2, and 51.2 ± 4.4 in the presence of remineralization solution and 31.7 ± 3.3, 15.6 ± 2.9, 16.5 ± 2.7, 16.8 ± 2.1, 13.1 ± 3.0, and 50.7 ± 2.8 in the presence of artificial saliva. There were no significant differences in surface microhardness measurements between the treatment groups. In conclusion, PHS resulted in a significant reduction of tissue loss compared with the negative control, but in comparison, the toothpastes containing Sn(2+) and F(-) ions were significantly more effective compared with PHS.

OBJECTIVE: A fractured whole crown segment can be reattached to its remnant; crowns from extracted teeth may be used as pontics in splinting techniques. We aimed to evaluate the effect of different storage solutions on tooth segment optical properties after different durations. STUDY DESIGN: Sixty central incisor crowns were divided into 6 groups (n = 10); Group 1 was kept dry; Groups 2, 3, 4, 5, and 6 were placed in an isotonic solution, water, milk, saliva, and casein-phosphopeptide-amorphous-calcium-phosphate (CPP-ACP), respectively, for 30 min, 12 h, 1 day, 1 week, and 3 weeks. Color values were measured using a colorimeter. Data were analyzed with Kruskal-Wallis tests, Mann-Whitney U-tests, and Friedman Wilcoxon tests with Bonferroni stepwise corrections (p < 0.05). RESULTS: ΔE* values varied from 0.3 to 15.3 over the 3 week period. Group 1 demonstrated the greatest color changes over all durations; Group 6 exhibited the least. L*, a*, b*, and ΔE* values varied between time periods in all groups; the differences were significant (p < 0.01), except for L* and ΔE* values in Group 2 and a* values in Group 6 (p > 0.01). Comparing ΔE* values, Group 6 was significantly different from the other groups for all durations (p < 0.01), except Group 4. CONCLUSIONS: A CPP-ACP complex solution seems a good choice for tooth fragment storage. Milk and saliva solutions may cause perceptible color changes if tooth fragments are stored for 3 weeks before use.

OBJECTIVES: The present study evaluated associated factors for developing early childhood caries (ECC) and Severe-ECC (S-ECC) in a group of children aged 24-71 months. Potential positive effects of early dental visit on formation of ECC is investigated as well. STUDY DESIGN: This was a multicenter, cross-sectional study conducted at three governmental and university pediatric dentistry clinics in 408 preschool children who were randomly selected from a total of 4116 children. The questionnaires administered to the mothers by interview and intraoral examination performed by calibrated pediatric dentists. The children were evaluated in three groups according to their caries experience as who had caries free, ECC and S-ECC. RESULTS: The following factors were significantly associated with caries formation: 1. Prolonged (i.e., >18 months) breastfeeding in preterm babies (OR=2.4) 2. Prolonged breastfeeding in children who started tooth brushing after 1.5 years of age (OR=3.7), 3. Sugar (p<0.001) and fruit-juice consumption (p<0.0001), and 4. Lack of periodic dental examination (p<0.05). Parental smoking habit does not significantly affect ECC development. Nocturnal bottle feeding and nocturnal feeding also affected S-ECC formation significantly (p=0.043 and p=0.005, respectively). CONCLUSIONS: There is a significant difference between the children with caries and caries-free associated with the brushing initiation age started before or after 18 months. If a child is under the risk of multiple caries factors, it is very difficult to evaluate which habits affect the caries formation or increase the severity of the caries lesions.

OBJECTIVES: The purpose of this study was to evaluate oral health care knowledge and behavior of women during pregnancy. SUBJECTS AND METHODS: The study population consisted of 351 mothers with children under 3 months of age who presented at Gülhane Medical Academy's Department of Pediatrics for a routine child check-up. Mothers were asked to complete a questionnaire about their knowledge and behavior regarding dental care during pregnancy. RESULTS: All the women who participated in the study had dental insurance, and most of them had high levels of education. Of the 351 mothers, 263 (75%) had heard about possible connections between oral health and pregnancy outcome, and 165 (47%) believed tooth and periodontal problems could affect pregnancy outcome. However, 256 (73%) women still believed that calcium would be drawn out of their teeth by the developing baby, and 151 (43%) believed in the erroneous statement 'A tooth for a baby'. 241 (68.7%) women had experienced oral health problems during pregnancy; however, only 48 (13.7%) visited a dentist during their pregnancy. CONCLUSIONS: Turkish women, despite having knowledge that adverse pregnancy events may be related to dental and periodontal problems, did not seek oral health care during pregnancy. This suggests the need to better educate medical providers to inform pregnant women to obtain oral health care during pregnancy.

The aim of this study was to identify the types and etiologies of dento-alveolar injuries among patients who were treated for injuries to maxillary and/or mandibular permanent teeth at the Gulhane Medical Academy, Department of Pediatric Dentistry, Center of Dental Sciences in Ankara, Turkey to provide a basis for determining optimal treatment approaches and educational needs. From a total of 4956 children aged 6-12 years (mean age: 8.91 +/- 1.95) applying to the Center, 472 children (9.5%) were found to have suffered dental injuries during a period of 2 years. Injuries were classified according to drawings and texts based on the WHO classification system, as modified by Andreasen and Andreasen. Injury rates were highest among children age 6 and ages 8-10. The most frequently injured permanent teeth were the maxillary central incisors (88.2%), and the maxillary right central permanent incisor made up 47.2% of all injured teeth. The most common cause of dental trauma was falling while walking or running (40.3%). Most injuries involved a single tooth (64.8%). The most common type of injury was enamel fracture (44.6%). There was a significant difference in gender, where boys more often suffered from a dental hard tissue and pulp injury than girls (P = 0.019), whereas there was no difference in gender (P = 0.248) in the distribution of periodontal injuries. Injuries were found to occur more frequently during the summer (P < 0.001). Children with increased overjet were 2.19 times more likely to have dental injuries than other children. Considering that the incidence of traumatic dental injury is highest among children ages 6 and ages 8-10 as well as the fact that patients with increased overjet are more prone to dental trauma, preventive orthodontic treatment in early mixed dentition may play an important role in reducing traumatic dental injuries.

OBJECTIVES: Common carious lesions owing to vomiting are not widespread in children. In this case, we aimed to report an 11-years-old male patient with common carious lesions due to repeated vomitings, chewing and eating difficulty and retarded growth with Multiple Hereditary Osteochondromatosis (MHO). CASE REPORT: An 11-years-old boy was referred to Department of Pediatric Dentistry in Faculty of Dentistry because of eating difficulty owing to common carious lesions. It was seen that the patient growth was generally retarded in extra-oral examination. Some exostoses were also present on the extremities. It was learned that he was previously diagnosed as MHO in Faculty of Medicine. Nausea and vomiting have been commonly occurring after taking of Didronat. Chewing and eating difficulty and inadequate nutrition were present because of bad oral hygiene, carious lesions and remained roots. Growth was negatively affected by malnutrition and MHO. RESULTS: Diet recommendations were given and oral hygiene behaviors were rearranged. Preventive, surgical, restorative and prosthetical dental applications were applied for dental treatments.
