Objective. To measure the distribution of dental caries in a group of Palestinian adolescents. Material and Methods. A sample of 677 individuals of both sexes (411 were females and 266 were males) their ages ranged from 12 to 15 year old randomly selected from schools in northern west bank in Palestine. Clinical examination was performed on all the subjects focusing on the index DMFT, representing the number of teeth that were either decayed, missing or with extraction indicated, or restored. Results. The prevalence of dental caries in the permanent dentition was 54.35% and was the highest in 15 age 75.75% in comparison to the other ages (12, 13, and 14) (40.57%, 41.76%, and 60.47%), respectively. The mean DMFT for the sample was 5.39 ± 2.85525 while the mean DMFT for different age groups (12–15) was 5.52 ± 2.766, 5.58 ± 2.745, 5.23 ± 3.304, and 5.23 ± 2.606, respectively. The prevalence of dental caries was higher in females with DMFT 5.39 ± 2.854 than males with DMFT 5.26 ± 2.891. Conclusion. High prevalent dental caries was found among Palestinian adolescents and higher in females than males. Strict preventive programs should be implemented. Further research with large samples required to include all adolescents from Palestine.

Abstract Background: Oral hygiene is one of the most important health issues in children that affects the health of children. This study aimed to investigate dental caries prevalence, Decayed, Missing, and Filled Teeth (dmft and DMFT Indexes) and the associated factors among 9 -11 years old children.Materials and Methods: This cross-sectional study was performed on 4226 primary school students aged 9-11 years old using the census method in Iran. Data were collected by valid and reliable researcher-made checklists. Data analysis was performed using SPSS software version 24 and using Kruskal Wallis, Mann-Whitney, and Logistic Regression tests.Results: The prevalence of permanent and primary dental caries in all students was 39.73% and 67.72%. The mean (standard deviation) of DMFT in the 9, 10 and 11 age groups were 0.6 (1.11), 0.97 (1.39) and 1.23 (1.63), respectively. The mean (standard deviation) dmft in the 9, 10 and 11 age groups were 3.14 (2.56), 2.46 (2.34) and 1.37 (1.84), respectively. There was a significant difference in DMFT and dmft between age groups (P<0.001). Results of multivariate logistic regression showed that there is a significant relationship between gender, birth rate, place of residence, mother's education, father's education and use of mouthwash with DMFT index (P<0.05). The results of multivariate logistic regression showed that the variables of insurance, residence and mother's job were significantly correlated with dmft index (P<0.05). Conclusion: In this study, the prevalence of dental caries was high. Variables of gender, birth rate, parental education, place of residence, use of mouthwash, having health insurance and mother's job were effective in predicting dental caries in students. it seems necessary to hold educational courses to increase awareness among students, educators, and parents about oral Health.

SummaryThe objective of the present study was to determine clinical and arthroscopic characteristics associated with dorso-proximal proximal phalanx (P1) fragments in Warmblood horses, as well as to examine their histopathological appearance. One hundred sixty-eight fragments were removed from 150 fetlocks of 117 Warmblood horses. Details of signalment and results of clinical examination were collected prior to surgery. After arthroscopic fragment removal and joint evaluation for synovial and/or cartilage abnormalities, the fragments were measured and evaluated histopathologically. The vast majority of the fragments (95.2%) were found medially, without predilection for front or hind limbs. In 10% of the joints, more than one fragment was present. The mean size of the fragments was 6.8 ± 2.6 mm. Only eight horses presented fetlock-related lameness. Horses of seven years of age and older (OR=13.32; p=0.033) and the presence of more than one fragment (OR=11.12; p=0.016) were significantly associated with lameness. Arthroscopic evaluation revealed one or more abnormalities in 50.7% of the joints. On histopathology, osteochondral fragments presented as a bony center covered with smooth hyaline cartilage on one side and some fibrous tissue on the other side. No clear histopathological signs were indicating precisely their origin. In Warmblood horses with dorsoproximal P1 fragments, the age (seven years and older) and the presence of more than one fragment in a fetlock significantly increased the risk of lameness. The osteochondral dorsoproximal P1 fragments could be defined as a developmental orthopaedic disease.

Measurements have been taken of the crowns of the teeth of seventy-nine chimpanzees, eighty-nine gorillas and sixty-three orang-outangs. Basic statistical data, comprising the mean, the number of skulls, the standard deviation and the standard error of the mean, are presented for forty-eight dimensions and indices of the deciduous teeth and for seventy-eight of those of the permanent dentition of each type of ape. A separation between the sexes has been made in the case of the permanent teeth. Further separation has been made into age groups, where necessitated by changes in dimensions due to wear. Even with the small samples resulting from these subdivisions, the standard error is seldom greater than 4 % of the mean, and therefore the figures obtained are reliable estimates of the variability of the teeth of apes. The data provide a basis for quantitative comparisons between the teeth of existing and fossil anthropoids.

There is a relationship between the use of fluoride, the reduction of dental caries and the increase of dental fluorosis. The purpose of this study was to analyze the fluoride kinetics in saliva after using the HappydentTM chewing gum, which contains 3.38 mg of fluoride as monofluorophosphate. Fifteen 7-9-year-old volunteers were instructed to chew the gum TridentTM (control) and HappydentTM on different days. Total saliva was collected for 3 minutes, at 0, 3, 6, 9, 15, 30 and 45 minutes after starting chewing. Salivary fluoride was analyzed with a fluoride-specific electrode (Orion 96-09) after acid hydrolysis. The data were analyzed by two-way analysis of variance and by Tukey’s post hoc test (p < 0.05). The mean amounts ± sd (mg) of fluoride released in saliva were 0.276 ± 0.126 and 0.024 ± 0.014 for HappydentTM and TridentTM respectively. The fluoride amount in the saliva samples after the use of Happydent was significantly higher than after the use of TridentTM in all experimental periods, except after 30 and 45 minutes. The high fluoride presence in saliva after the use of Happydent may be significant to prevent dental caries and this should be evaluated in clinical researches. On the other hand, children at an age of risk for dental fluorosis should avoid the use of HappydentTM.

Objective. To analyze the dynamics of prevalence and severity of dental caries among 12- and 15-year-old schoolchildren in six regions of Lithuania. Material and methods. A total of 5910 schoolchildren aged 12 and 15 years were examined. Dental caries was diagnosed according to the criteria of World Health Organization. The prevalence of dental caries was calculated by dividing the number of children with caries by the number of all children examined and expressed as percentage. Severity of dental caries was described by DMF-T index. DMF-T indices of individual persons as well as each age group were determined. Oral hygiene was evaluated by a simplified oral hygiene index. Fluoride concentration in Kretinga was 1.6–2.2 ppm; in the other regions, it varied between 0.2 to 0.4 ppm. Results. The prevalence of dental caries among 12-year-olds was 88.4% in 1983 and 85.5% in 2005; among 15-year-olds, it was 95.5% and 92.9%, respectively. Mean DMF-T score decreased from 4.5 (in 1983) to 3.7 (in 2005) among 12-year-olds and from 6.4 (in 1983) to 5.6 (in 2005) among 15-year-olds. Oral hygiene index decreased from 1.69 in 1983 to 1.34 in 2005 among 12-year-olds and from 1.46 to 1.22 among 15-year-olds, respectively. Conclusions. A tendency towards decrease in the prevalence and severity of dental caries was observed, when caries prevention program was running. Correlation between oral hygiene and DMF-T was observed in both age groups. Decreased prevalence and intensity of dental caries among 12- and 15-year-olds were associated with improved oral hygiene, usage of fluoride toothpaste, and fluoride content in drinking water.

Background/Aim. Oral health is an integral part of general health and an important factor in the overall quality of life. The purpose of this study was to investigate the prevalence of dental caries among the children from the SOS Children?s Village in Croatia. Methods. The dental examinations based on the World Health Organization criteria were performed on 88 children from SOS Children?s Village in Croatia. The teeth were clinically examined with standard dental instruments using the visual-tactile method under standard light. The clinical indexes of decayed, missed, and filled (dmft and DMFT, for primary and permantnt teeth, respectively) and decayed, missed, and filled surfaces (DMFS), as well as the significant caries index (SiC) were recorded. Results. Among the children from the SOS Children?s Village caries incidence were 57.94%. The mean dmft, DMFT and DMFS of all children was 1.82, 1.90 and 2.82, respectively. The highest mean dmft and DMFT score of 4.24 and 2.56 was found among 7?10 and 11?14 years old children, respectively. The highest mean DMFS score of 3.85 and 3.90 was found among 11?14 years old children and among the children from the SOS Children?s Village Lekenik, respectively. Among all children, the SiC index was 4.69. There was a significant difference between age groups and children?s place of residence in DMFT, DMFS and SiC. Conclusion. Prevalence of dental caries is low among the children from the SOS Children?s Village in Croatia compared to the children who lived with biological families.

Introduction. In 2016, 5-, 7- and 12-year-old children from the Małopolskie region were included in the study of oral health as part of the Nationwide Monitoring of Oral Health programme, which has been periodically implemented in selected index groups of the Polish population since 1997. Aim. To evaluate the prevalence and level of dental caries in 5-, 7- and 12-year-old children from the Małopolskie region and to observe the dental caries trend in this region in recent years in relation to the Polish population. Material and methods. The study covered 673 children from the Małopolskie region, including 223 aged 5, 225 aged 7 and 225 aged 12 years. Dental condition/state of dentition was examined according to the WHO recommendations and criteria. The prevalence and level of dental caries in children from the Małopolskie region were evaluated and compared with the results of earlier studies from this province. The obtained results were also compared with the results for the entire Polish population from the current and previous nationwide monitoring studies. The studies were conducted upon the consent of the Medical University of Warsaw Ethics Committee no. KB 190/2016. Results. Dental caries prevalence in 5-, 7- and 12-year-old children from the Małopolskie region that were covered by the study was 74.9, 84.9 and 81.8%, respectively. The average values of dmft were 4.55 (in the age group of 5) and 5.38 (in the age group of 7), while DMFT for particular age groups was 0.03, 0.56 and 3.54, respectively. Slight decrease in the value of these indications of caries is noticed for 5- and 7-year-old children from the Małopolskie region (decrease in prevalence by 2.5 and 6.7%, respectively, as well as a fall in the value of dmft by 0.71 in the age group of 5, relative to 2011). The group of 12-year-old children from our region, as the only one from the entire Polish population of children of this age, have kept a downward trend of caries prevalence (a fall by 12.7% relative to the monitoring study from 2010). This reduction needs to be confirmed in the next monitoring studies. Conclusions. The presented results indicate stable high prevalence of dental caries in children of the Małopolskie region and in the whole country. It is therefore necessary to enhance actions intended to improve this situation through education of both children and their parents, widespread prophylaxis, and greater health-oriented awareness of patients.

Objective: The purpose of the study was to determine the cariostatic potential of a chewing gum containing tea polyphenol. Study design: A total of 157 schoolchildren aged 8-9 years were randomly allocated into three groups. Two groups received chewing gum with or without tea polyphenol. A third group did not receive any chewing gum. A single examiner assessed the caries status for all participates at baseline, 12 months and 24 months. A one-way analysis of variance (ANOVA) was performed to evaluate differences among the groups at each interval. The Chi-square test was used to compare the caries-free rate among the three groups. Results: The mean DMFT increment was 0.17 for the polyphenol gum group, 0.60 for the control gum group, and 1.15 for the no gum group. Children who chewed gum containing tea polyphenol had a significantly lower mean DMFS increment over the 24-month period than did the other two groups (p &lt; 0.05). The caries-free rate in the polyphenol gum group was significantly higher than that in the other two groups (p &lt; 0.05) after two years. Conclusion: These findings indicated that the oral application of chewing gum with tea polyphenol has an inhibitory effect on dental caries.
