Abstract

the purpose of this study was to compare the Vickers hardness of sound dentin after carious tissue removal using the chemo–mechanical method and the conventional rotary method. Materials and Methods: The carious dentin of thirty extracted human primary lower second molars was removed using Carisolv™ and conventional rotary methods. The Vickers hardness number (VHN) of the cavity floor was determined and the adjacent sound dentin of each tooth was used as a control reference. Results: The results indicated no statistical difference in the microhardness of the dentin in the cavity floor after treatment with Carisolv™ gel and conventional rotary method and no statistical difference in the microhardness of the dentin of both types of caries removal compared with the adjacent control areas. Conclusions: The Carisolv™ gel does not cause a significant change in the microhardness of dentin that remains after being submitted to carious tissue removal.

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

Aims: The aims of the present study were to determine if primary teeth eruption and the presence of
enamel defect are affected by low birth weight and prematurely of birth. Materials and Methods: The
total subjects of (420) child aged 4 – 24 months were included in this study, consisted of (210) prematurely
born (<37 gestational weeks and birth weight < 2.500 Kg) children and 210 control children (&#8805;40
gestational weeks and birth weight &#8805; 2.500 Kg). Those children selected randomly the children who
came to the primary health care centers with their mother for vaccination and the mothers asked to participate
in this study. For each child, clinical exanimation was performed in dental chair. The criterion
used for enamel defect to include various enamel hypoplasias, deficiency of enamel in the form of pits,
grooves or other quantitative surface loss and enamel hypocalcifications and opacities. Data were analyzed
using numbers, percentages, means and standard deviations. T – test, Z – test Chi – square (X2)
test were used for determining the differences concerning different variables. The differences were
considered significant at p&#8804; 0.05. Results: There was no significant difference (p>0.05) between different
genders numbers among in each age group for the preterm and control children. The results
showed significantly (p<0.05) delayed eruption of the primary teeth in the prematurely born children as
compared with the control children in all age groups except in 4 – 6 months age group, also there was
significantly higher percentages of enamel defect present in preterm children, than in control children
in all age groups except in 4 – 6 months age group. Conclusions: The findings indicated that the eruption
of deciduous teeth was delayed and the percentage of enamel defect was significantly increased in
prematurely born children.

Abstract

Aims: To evaluate the effect of two types of disinfectant solutions(2% alkaline glutaraldehyde, 1% sodium hypochlorite) in wettability of three types of elastomeric impression materials (light body) which are used in crown and bridge restorations at different times of immersion. Materials and me-thods: Three types of elastomeric impression materials (light body) were formed on a flat acrylic resin block and allowed to set(five specimens of each impression material was done for each immersion time(15,30 and60 minutes)of each disinfectant solution in addition to control groups). The wettability is indicated by measuring the contact angle of aqueous solution of CaSO4 on surface of cured impres-sion materials. Results: indicated no significant effect of immersion times on wettability of three types of impression materials. The hydrophilic type produce high wettability. Conclusions: The disinfectant solutions have different effects on each impression material. Sodium hypochlorite has the greatest beneficial effect on wettability

Abstract

Aims: To identify the clinical picture and the association between dry socket and severe postoperativedevelopment with one of the systemic risk factors (typhoid fever). Materials and Methods: Twentyadult (both sexes) patients attended dental clinic searching for different dental treatments were studied.The clinical picture of 6 months period study was evaluated by completing two case sheet forms. Theywere diagnosed having dry sockets and severe postoperative pain. Blood samples were taken for bacteriological,serological and hematological study to diagnose typhoid fever. These tests included WAT,WFT, WBCs and blood culture. Results: Significant correlation existed between postoperative painand typhoid fever examined by BC and the highest percentage was with dry socket (61.5%) followedby WFT (57.1%(, WAT (44.4%) using two tests for diagnosis showed that WFT and BC gave 97.9%positive for dry socket and Kappa test was 88%, while WAT and WBCs or WFT and WAT gave theleast non significant correlation. Conclusion: There was a strong correlation between dry socket andtyphoid fever and the most sensitive tests for diagnosis was BC followed by WFT, WBCs and WAT

Abstract

Aims: To evaluate the effectiveness of some nursing caries factors related to presentation such as gender variation, pattern of feeding habits, parent’s education and area of residence through a random sample of preschool children in Mosul City. Materials and Methods: A sample of 271 children was selected from 2–5 year olds, attending the Pedodontic clinic of Dentistry College at Mosul University and some others private dental clinic in Mosul City. For each child, clinical exanimation was performed on dental chair. The examination was conducted with a visual and non tactile technique. The criterion used for nursing caries was the presence of caries on the labial or lingual surfaces (smooth surface) of at least two maxillary incisors with absence of caries in mandibular incisors. The questionnaire was designed to collect general information on each child: name, age, gender as well as questions including area of residence (rural or urban) and parental education levels. Dietary information sought included past and current infant feeding practices either; breast feeding, bottle feeding or mixed of both. Chi – square (X2) test was used to determine the gender differences for each group and between total samples of different groups. The differences were considered significant at p ≤ 0.05. Results: A total of 271 children with nursing caries, 146 (53.87%) males and 125 (46.13%) females of 2 – 5 years old were included in this study. The higher number of children was from rural area than those from the urban area with significant difference (p≤ 0.05) between them. Concerning parents’ education, nursing caries was significantly the higher amongst children of mothers and fathers with the lowest level of education. The lowest percentages of children were seen in the children of parents educated to beyond college level. The higher number of children was of breast feeding group followed by bottle feeding group and mixed feeding group with a significant difference (p≤ 0.05) between breast feeding and mixed feeding groups only. Meanwhile, there was no significant difference (p>0.05) between different genders among all variables groups. Conclusions: The occurrence of nursing caries in preschool children appears to vary significantly with respect to the area of residence, parental education and feeding habits groups. The improvement of different familial factors may have an impact on the oral health of children.
