Abstract

The purpose of the study was to determine the prevalence of mottled enamel in a group of school students lived in area with high and low natural fluoride contained drinking water in Iraq. The study was conducted among (874) school's students aged (13-16) years from randomly selected intermediate schools in two provinces in Ninevah Governorate, Tour hundred and eight students who had lived since birth in high natural fluoride level area (Sinjar province) (2.05-2.22 ppm fluoride) and (466) students lived continuously from birth in low natural fluoride level area in their drinking water (Talkaif province) (0.11-0.19 ppm fluoride). Al-Alousi index has been used to assess mottled enamel. The results show that the prevalence of mottledenamel in Sinjar province is (95.8%) within individuals and (65.3%) within teeth, with significant difference between the sex; while the prevalence of mottled enamel in Talkaif province was (18.1%) within individuals and (3.6%) within teeth, with no significant sex difference. The high percentage of mottled channel was of type "A", followed by types "B" and "E" in high fluoride area, while in low fluoride area also type "A" reported thehigh prevalence, followed by types "B" and "C".

Abstract

This purpose of this study is to evaluate the effectiveness of vanillin (2%) alone and with Amber dentifrice on the cariogenic bacteria (Streptococcus mutans and Lactobacillus). The vanillin material was prepared in this study by the use of pure vanillin (2%). Two microorganisms were selected to examine the antimicrobial activity of the vanillin against dental caries. These microorganisms are Streptococcus mutans and Lactobacillus; both are isolated from the dental plaque on the carious surface and from saliva. For the assay the turbidity method was used as described by Abdul-Rahman (2001), using the mean value of optical density to record the growth of bacteria. This study showed that the vanillin (2%) alone and withdentifrice reported significantly less mean value of optical density for both bacteria compared with the control read. That means it is effective in controlling and preventing dental caries by reducing the growth of cariogenic microorganisms.

Abstract

This study was designed to evaluate the relationship between the occurrence of root surface caries (RSC) and a subject's dental health habits such as the frequency of tooth brushing and the use of other cleaning aids such as chewing stick and the dental floss in the adult population aged(30-70) years in Mosul city. A sample of (1270) subjects [719 (56.6%) males and 551 (43.4%) females] were collected randomly from different eight factories, seven primary schools, eight secondary schools and five colleges from Mosul University. According to age, the sample was divided into four age groups (30-39, 40-19, 50-59 and 60-69 years). The results of the study revealed that subjects with RSC in the young age group (30-39 years) claimed to brush their teeth once a day and twice a day or more, whereas subjects with RSC in the old age group (60-69 years) claimed to brush their teeth infrequently. Statistically, the differences between subjects with and without RSC were significant for all age groups. The study showed that generally subjects with and without RSC who claimed never use other cleaning aids reported higher percentage that those who used other cleaning aids. Indeed, those who claimed to use chewing stick displayed high rate than those who use dental floss. It was concludedthat dental health behavior influence root caries occurrence and that caries on root surface is associated with poor dental health habits

Abstract

The aim of this study was to estimate the prevalence and severity of gingivitis and oral hygiene condition in school children aged (11) and (12) years in peri-urban area (QadhaSinjar). A sample of (388) school children aged(11) and(12) years (184 boys and 204 girls) were examined using plaque index score by Silness and Loe, and gingival index by Loe and Silness. The severity of gingival inflammation and the frequency of tooth brushing were recorded. The results show that the mean plaque score for the total sample was (1.06); the girls reported less significant mean plaque score than boys. The mean gingival score was (1.45) for the total sample; also the girls reported less significant mean gingival score than boys. Three quarters of children have moderate gingivitis. The study revealed that (63.7%) of the total sample did not brush their teeth or brush infrequently. Therefore, oral health education for school children is an essential activity for promoting, establishing and maintaining optimal oral health and preventing oral diseases.

Abstract

This study was carried out to compare the location of occlusal plane, which exists in the natural dentition with the prosthetic occlusal plane when oriented according to Camper's line. Lateral cephalometric radiographs were obtained form (106) dentate subjects using a standard radiological technique. The results showed a variation between the orientation of the two planes. The plane extending from inferior border of ala of the nose to the inferior border of external auditory meatus was found to be reliable for the determination of occlusal plane of the artificial teeth.

Abstract

This study was designed to investigate the relationship between root surface caries and systemic disease (diabetes, hypertension and heart problem) in the adult and elderly population in Mosul City, Iraq. A sample of (1270) subjects [719 males (56.6%) and 551 (43.4%)] are collected randomly from different eight factories, seven primary schools, eight secondary schools and five colleges from Mosul City. According to age, the sample was divided into four age groups (30-39),(40-49),(50-59) and (60-69) years. The result indicated that the subjects with systemic disease have more effected by root surface caries than the subject medically fit, for the age groups below (60) years. These differences were highly significant, while the subjects in the age group (60-69) years reported the very high percentage affected by root surface caries for both groups with no significant difference between them. The study revealed that the males with systemic disease have a higher significant root surface caries than the females in all age groups except for the age group (40-49) years. For total group with root surface caries, the percent with systemic disease in males was slightly higher (36.8%) than females (29.8%) with no significant difference between them.

Abstract

This study was undertaken to elucidate the effect of fixed orthodontic appliance on the microbial composition of dental plaque and to detect any difference between the isolated microflora from different teeth before and during treatment. Twenty subjects (15 females and 5 males) between (12) and (23) years of age, participated in this study. From each subject, four swabs were collected; two in the anterior region (upper and lower central incisors) and two in the posterior region (upper and lower first molars). Bacterial examinations were performed before the beginning of the treatment and (4-6) weeks after placement of orthodontic appliances, so (160) swabs were collected. The composition of dental plaque determined was under light microscope. The statistical analysis was performed and the results showed a variety of microorganisms from supra-gingival plaque samples in pre-and during treatment fixed orthodontic patient. Changes during treatment consisted of an increase in the Peptpcocci,Klebsiella,α- Streptococci, Pseudomonas and Escherichia coli in certain locations. Conversely, a decrease in the Peptostreptococci,Bacteroids,Veillonella, Staphylococci,Streptococcus mutans, Klebsella, Candida, Lactobacilli and Propeniobacterium in different locations, whereas other microorganisms and some of the above-mentioned microorganisms in certain locations showed insignificant differences. The comparison of microflora between different teeth indicated that the molars presented a significantly more microorganisms than incisors did specially in pre-treatment, whereas the upper incisor in both pre-and during treatment presented more microorganisms than lower incisor; while the lower molar exhibited more microorganisms than the upper molar particularly during treatment.

Abstract

A comparison between the location of mandibular foramen on ten dry mandibles has been used in this study with its location on the two extraoral radiographic projections taken for each dry mandible. First projection with the use of panoramic radiograph and the second projection have been taken by lateral oblique jaw projection. The results are shown no significant difference between the measurements are taken from both radiographs. But still the lateral oblique jaw radiograph is more resoluted and accurate in the localization of the mandibular foramen.

Abstract

The aims of this study are to determine the prevalence of dental caries among thalassaemic major patients and compare the results with normal subjects. The study sample consisted of (35) thalassaemic patients and (35) non thalassaemic controls, all aged (14-22) years. Examination of the patient's teeth for dental caries prevalence in the two groups was performed using two methods: clinical and transillumination. There was no statistical difference in the prevalence and severity of dental carries between thalassaemic and non-thalassaemic groups. The results of this study indicate that the percentage of treated teeth in thalassaemic group was very low in comparison with non thalassaemic patients and this difference is statistically significant for all age groups except the last age group (20-22), where it is not significant.
