This study was carried out to evaluate the action of 0.2% sodium fluoride (900 ppmF), and 0.2% chlorhexidinegluconatemouthrinses besides tooth brushing on plaque and gingival indices. To achieve this aim 45 patients undergoing fixed orthodontic therapy were divided into 3 equal groups randomly which were on tooth brushing only, tooth brushing with 0.2% sodium fluoride and tooth brushing with 0.2% chlorhexidinemouthrinses. The second group rinse with 10 ml of sodium fluoride once weekly for 8 weeks, while the third group rinse with 10 mi of chlorhexidine twice daily for the same period, the plaque and gingival indices were scored at base-line and then evaluated after 4 and 8 weeks. The present study revealed that the mean plaque index was significantly reduce (p<0.05) for the chlorhexidine and sodium fluoride patients in comparison with the first group throughout period of study. A similar trend was noted with gingival index as the lower values were recorded to the chlorhexidine groups, moreover, analysis of variance showed significant differences among groups and the chlorhexidine means were the mostly affected one. These results indicate that sodium fluoride could be use also for plaque and gingivitis control in addition to its anticariogenic action for patient undergoing orthodontic treatment.

Al-Rafidain Dental Journal, 2001, Volume 1, Issue 2, Pages 104-112
DOI: 10.33899/rden.2020.166030

The clinical examination involves eighty one males Yemenis, in Dhamar of age 15-45 years old and of similar and regular daily habit of chewing Khat unilaterally at the left side of the oral cavity to enjoy the amphetamin - like effect of Khat as a stimulant in a company with their friends under special environment & social rules in Yemen since a lot of years ago.
The sample was divided equally into three age groups, (15-24 years), (25-34 years) and (35-45 years). The periodontal health status examined clinically to measure the plaque index, gingival index and periodontal pocket depth.
Measurements divided into three groups, non - chewing right site of the mandible, and chewing left buccal site and chewing left lingual site of the mandible in the same individual.
The periodontal health status according to the three parameters, revealed that the scores at the chewing site were higher than that at the non - chewing site, and higher buccally than lingually at the same chewing site.
With the age and prolong abuse of Khat chewing, the scores increased and the periodontal pocket depth significantly differed in the age group (35-45 years) than the (15-24 years) and (25-34 years), age group.
The periodontal pockets were significantly higher buccally than lingually at the same chewing site, may be due to the manner of Khat chewing, where the leaves of Khat accumulate gradually and held in the lower buccal pouch unilaterally in a bolus for several hours daily.

The main objectives of this study were to determine the effect of different nickel - chromium alloys with different surface treatment bonded to enamel tooth surface on the shear bond strength. Seventy five wax disc-shaped samples were prepared. These discs were divided into three groups, (25) in each. The first group was casted with CB-Bland 72 alloy, the second with CB-soft alloy, and the third group with Kera - N alloy. For surface treatment procedures each group was divided into five subgroups, five samples in each: the first subgroup was sandblasted with (50) μm Al2O3 plus electrolytical etching. The second subgroup only electrolytically etched; the third subgroup sandblasted with (50) μmAl2O3. The fourth subgroup sandblasted with (100) μm Al2O3, and the fifth subgroup received no surface treatment. The metal discs were bonded to the labial surface of upper central and lateral incisors using intermediate resin and adhesive luting cement. The samples were thermocycled between (5-60) C°± (2) C° for (500) cycles at (1) minute dwell time and then stored in distilled water in an incubation at (37) C° for seven days. After that the shear - bond strength were tested.
The results showed that the mean shear-bond strength of CB-Bland 72 alloy was found to be greater than that of Kera - N and CB-Soft alloys, and surface treatment with (100) μmAl2O3 procedure exhibit the highest bond strength.

An In vitro study was carried out to compare the effects of the Smear layer and the pretreatment of the foot canal wall with tubular occluding desensitizing agent (6% ferric-oxalate) or a bonding agent on the coronal seal of endodontically treated teeth.
Seventy freshly extracted human teeth with single and straight canals were used in This study. The teeth were divided into five experimental groups: twelve teeth each, withone positive and one negative control for each. Group I: With intact smear layer, Group II: Without smear layer. Group III: With intact smear layer and with ferric-oxalate painting of the canal walls. Group IV: Without smear layer and with ferric-oxalate painting of the canal walls. Group V: Without smear layer and with bonding agent.
After canal obturation the access cavities were exposed to natural saliva then Pelikan ink. Teeth were cleared and linear dye penetration measured. The results showed that the removal of the smear layer significantly increased the tightness of the coronal seal, and pretreatment of the canal walls with ferric-oxalate significantly decreased the coronal microleakage more than with or without smear layer. Using the bonding agent with a hydrophilic primer, after removing the smear layer, showed significantly less microleakage than all other groups.

Most orthodontists and clinicians used to evaluate the patient's profile, clinically and radiologically. To obtain a correct diagnosis, most clinicians now realize the importance of an appraisal of the patient's facial esthetics from the frontal and lateral aspects.
He aim of the present study is to establish the cephalometric mandibular norms of Iraq adults (18-25 years) by means of linear and angular analysis of PA and LAT cephalometric radiographs. The sample is collected from the students of Mosul University and is consisted of 100 Iraqi adults (50 males and 50 females) aged (18-25 years) with class one normal occlusion.
LAT and PA cephalometric radiographs are taken for each subject, Twenty seven cephalometric measurements (11 angular and 16 linear measurement).
Statistical analysis of data is done by using computerized statistical program Minitab. The angular measurements of the mandible showed that the females are significantly larger than males in the N.S.Ar, SN-MP, SN-Occ and B.Me-MP, where as the S.N.B., S.N.B., S.N.Pog and S.N.Id are significantly larger in the males, and the rest of the angular measurements show no significant difference between the two sexes. All the linear measurements of the mandible for males are significantly larger than the females.
