Abstract

Background: Adolescence is one of the most dynamic stages of human development. However, Oral health is an integral part of public health, significantly impacts on the quality of life. OHE program is an important issue that should be given to them. The aim of this study was to evaluate oral health outcomes on adolescents' oral health by teachers and mothersMaterials and Methods: The study was carried out in seven schools of Diyala - Baquba city. This 14-weeks duration study assessed the effectiveness of school OHE program on oral hygiene status, gingival health, and halitosis assessment of 80, 12 year-old, both genders of school adolescents. From the selected schools, one group was supervised by the teachers and the other was supervised by the mothers. General and oral health assessments were evaluated using a questionnaire. A three days training workshop was organized for the teachers and mothers. Oral hygiene, gingival health, and halitosis assessment were assessed using plaque indices, gingival indices and halitosis scores respectively. the resulting data were statistically analyzed using SPSS version 20.Results: Plaque, gingival and halitosis scores reductions were highly significant. Results recorded gingival index, and halitosis scores were lower among the teacher-led group compared to the mother-led group. Statistically, high significant differences were found (P< 0.01).But there is no significant differences were noticed between the groups for plaque index (p>0.05).Conclusions: The OHE program was effective in teacher-led group than mother-led group in improving oral hygiene status, gingival health and halitosis scores of adolescents

Abstract

To detect the levels of fluoride (F), zinc (Zn) and lead (Pb) in primary teeth and drinking water and their relation to dental caries experience in school children aged 6–12 years living in two distinct areas in Ninevah Governorate using two different sources of drinking water supply. Materials and Methods: The samples consisted of 120 freshly extracted highly mobile free of dental caries human primary mandibular teeth and ten wells water samples with ten tap water samples which had been chosen randomly. The samples were analyzed for F by fluoride sensitive electrode and for Zn and Pb by computerized atomic absorption spectrophotometer. Assessments and recording of caries experience were done by application of decayed, missing and filled surfaces (dmfs) index for primary dentition. Results: Statistical analysis of the results indicated that the mean F and Zn concentrations in the teeth were 244.35 + 167.49 ppm; 87.41+ 36.64 ppm respectively of the rural children were significantly higher than in the teeth of urban children (104.53 + 52.75 ppm; 65.19+ 28.79 ppm respectively). Meanwhile the concentration of Pb in the teeth of the urban children (1.62+0.41 ppm) was significantly higher than in the teeth of rural children (0.94+ 0.80 ppm)(p<0.001). Statistically significant higher F concentration in the wells water (3.39+ 0.25 ppm) than urban water supply (0.19+ 0.07 ppm) (p<0.001). Statistically significant higher Zn concentration in the urban water supply (0.1.34+ 0.31 ppm) than wells water (0.07+ 0.03 ppm) (p<0.001), but Pb concentration in wells water was not detected. Statistically significant higher caries experience was found in urban children than in rural (p<0.001). In the rural and urban areas, a negative correlation in the dmfs with F and Zn concentrations in teeth while a positive correlation with Pb was observed. Conclusions: A highly significant F and Zn concentrations in primary teeth were found in rural area than the urban and the opposite was true for Pb concentration. High significant F concentration was found in the wells water than urban water supply, and the opposite was true for Zn, but Pb concentration in wells water was not detected. High significant differences in dental caries indices were found in urban children than in rural children

Abstract

to determine the prevalence of erosion in children and to compare different etiological factors related to dental erosion. Materials and Methods: A study of dental erosion conducted among 3125 children, 11–12 years old which represent delay mixed dentition in 27 primary schools in Mosul city, comprising a study group with 35 erosion children, 22) males and 13 females. The other compared controlled subject are 35 children without erosion and caries free random sampling matching for both age and sex. The level of erosion was recorded using modified tooth wear index (MTWI), standardized methods for salivary flow rate and PH measurements were conducted. The role of various possible factors related to oral health in general and to dental erosion in particular was assessed for both study and control groups by means of multiple choice questionnaire. Results: showed that the prevalence of erosion in the sample was 14.3% distributed as mild erosion (7.55%), moderate erosion (5.6%) and only sever erosion (1.15%). A significant lower salivary flow rate mean (0.38 + 0.38 ml/min) and salivary PH mean (7.35 + 0.37) in erosion group were found, whereas in the control group they were 0.47 + 0.19 ml/min and 7.50 + 0.25 respectively. The results demonstrated a significant higher fruit juice intake, carbonated drink intake in erosion group than in their controls. The erosion group showed no significant difference in drinking habit and time of drinking of the soft drink compared with control group. Conclusion: The dental practitioners must be aware of their important role to recognize dental erosion and understanding its pathogenesis so that correct diagnosis and management of erosion can be performed.

Abstract

Background: Tooth avulsion, one of the most severe forms of dental trauma, is characterized by completedisplacement of the tooth from its alveolar socket. It accounts for 0.5% to 16% of traumatic injuries in the permanentdentition. Avulsion of permanent teeth occurs most often in children 7 to 9 years old, an age when the relativelyresilient alveolar bone provides only minimal resistance to extrusive forces. The best way to preserve a tooth that hasbeen avulsed is to put it back into its socket as quickly as possible. Several storage media had been suggested topreserve the viability of the periodontal ligament cells. It was suggested to place the tooth under the patient'stongue in cases in which immediate replantation was not possible. Eagle's culture medium had also been used forstoring teeth. Also it was suggested to store the avulsed tooth in milk, Hank's balanced salt solution or saline. Chickenegg white may also prove to be a suitable storage medium for the avulsed teeth.Materials and methods: Eighty freshly extracted lower first premolars of special criteria were used in this study. Theteeth were divided into control groups in which the teeth were left to dry after extraction for 0 minute, 30 minutes, 4hours and 8 hours before being treated with the enzymes and experimental groups in which the teeth were left to dryafter extraction for 30 minutes, 4 hours and 8 hours before being immersed in a different experimental storage mediaand then treated with the enzymes to isolate the fibroblast cells of the periodontal ligament.Results: Results of this study showed that zero minute dry time was the best time for the control group in maintainingviable fibroblast cells followed by 30 minutes, 4 hours and 8 hours dry times. For the experimental groups, 30 minutesdry time was the best time followed by 4 hours and 8 hours dry times. Results of this study also showed that Hank'sbalanced salt solution was the best storage media that maintain viable fibroblast cells of the periodontal ligament ofthe extracted teeth with a significant difference compared to the control group and with no significant differencecompared to the other experimental storage media. Results also showed that the albumin of the chicken egg,honey and the glycerol were also good storage media with no significant difference than the control group.Conclusion: Hank's balanced salt solution was the best storage media in maintaining viable cells viability.Thirty minutes dry time was the best time in maintaining viable periodontal ligament cells followed by 4 hours and 8hours dry time after teeth avulsion

Abstract

Background: Possibly the greatest deterrent to the development of an ideal restorative material is the leakage thatoccurs along the restoration, tooth interface. There is yet no truly adhesive dental material that exactly duplicatesphysical properties of the tooth structure. This in vitro study was carried out to compare the microleakage of twotypes of restorative materials used in pediatric dentistry Colored light curing compomer(Twinky star) and nanoceramic restorative material (Ceram.x)) with that of amalgam by measuring their ability to prevent dye penetration.Materials and Methods: Standardized Proximo-occlusal cavity preparations were prepared in 30 extracted soundprimary first lower molars. Pulpotomy was performed, and pulpotomy paste filled the pulp chamber with hard settingcement over it all have same occlusal depth. The teeth were then randomly divided into three groups: Group A:filled with Amalgam. Group B: filled with compomer (Twinky star). Group C: filled with nano ceramic (Ceram.x).After that the teeth were stored in distilled water for 30 days at 37 °C in an incubator and during the period of storagethe teeth were subjected to 300 thermal cycles (10 cycles each day), then sectioned to be examined under thestereo microscope.Results: Data was analyzed using ANOVA test with help of spss soft ware, even though nano ceramic (Ceram. X)showed higher resistance to dye penetration, when compared to compomer (Twinky star and amalgam), therewere no significant differences between the three studied groups in their resistance to dye penetration.Conclusion: Depending on the ability to prevent marginal leakage, nano ceramic (ceram.x) and compomer (Twinkystar) restorative materials can be used as an alternative to amalgam in restoring pulpotomized primary teeth
