Abstract

The aim of the study is to evaluate the oral hygiene and gingival health and to identify if there is any variation between sex and age group among adolescents and adult population in rural area (sharkhan village), in Ninevah governorate. A sample of 203 individuals aged 1-44 years (84 males and 119 females) were examined using plaque index score by silness and loe (1964) and gingival index by loe and silness (1963). The results show that mean plaque score for total sample is (1.29), the plaque index was increase with age, the females reported less mean plaque score than male, however, there was no statistically significant difference of oral hygiene by sex. The mean gingival score was moderate (1.26) for total sample and it was increase with age significantly, the mean gingival score was slightly better in females in females than males with statistical significant between them. The study revealed that about (50%) of the total sample did not brush their teeth or brush infrequently. Therefore the objective of dental health education to those subjects is to brush their teeth regularly and to improve the effectiveness of oral hygiene practice.

Abstract

New orthodontic adhesives should be put under vitro and vivo investigation to evaluate their efficiencies and disadvantages, so that, Concise, No Mix and Right On orthodontic adhesives were tested in vitro and evaluated clinically by treating (15) cases. These adhesives were used in bonding (10) human sound extracted premolars for each one according to the manufactures instructions, and then rebonded new brackets to these tested teeth after cleaning and polishing. The adhesive were used in bonding the brackets to the 40 teeth clinically (five upper dental arches) for each type, according to their manufacturer ' s instructions. The lowest number of failure brackets was within the use of concise adhesive. The shear bond and rebond strength were measured in compression test Machine in Mega Pascal (Mpa). The results showed that the Concise adhesive had strongest bond and rebond strength in vitro and clinically than that No Mix and Right-On adhesives and the later adhesives had adequate bonds strength and more successful in bonding anterior brackets

Abstract

A survey was carried out to determine the various etiologic factors leading to root canal therapy. The study included cases of root canal filling that had been done by undergraduate students in conservative department. Results of this study can be concluded in the following: 1. Necrotic pulp and irreversible pulpits were the most frequent reasons for root canal filling and trauma was the second common reason. 2. The frequency of maxillary central incisor was the most often for endodontic therapy. 3. The frequency of endodontic therapy by arch showed three times as often in upper arch as in the lower arch. 4. Preoperative pain was noted in 58.3% of the patients.

Abstract

This study evaluated resin-bonded fixed partial dentures (FPDs) clinically. Forty patients received 40 resin-bonded FPDs. Two types of luting materials were used, Super Bond Crown and Bridge Material and Degufill SC composite. The metal frame works for Super Bond Crown and Bridge Material were sandblasted only, and for Degufill SC composite were electrolytically etched, Clinical evaluation were performed at 3, 6, 12 and 24 months after cementation. None of the prostheses bonded by Super Bond Crown and Bridge Material lost retention, whereas two of the acid etched retainers required replacement after one year, Resin bonded prostheses appear to be favorable alternative to other types of fixed partial dentures.

Abstract

The acid etching effect of a new viscous 35% phosphoric acid dissolved in glycerol and known 35% gel phosphoric acid agent were investigated in vitro on 40 sound extracted premolars using concise orthodontic adhesive in bonding stainless orthodontic brackets. The results showed no significant difference in bond strength between the two etching agents at 0.05 significant level. But samples etched with Viscous phosphoric acid have higher numerical value. This finding was supported by the clinical investigation on 10 orthodontic patients in which the number of failure brackets was 8 for viscous phosphoric acid etching agent and 12 for gel phosphoric | acid agent after 11 months of treatment

Abstract

The aims of this study were to determine the mean shear bond strength of fast setting fluoride releasing core materials (vitremer core build up restorative system,compoglass F resin modified glass ionomer,Tetricceram composite and Definite composite) to dentin and the effect of one hour, 24 hour, and one week storage on mean shear bond strength. One hundred thirty molar teeth Were mounted in a plastic cylinder using self-curing resin, then the teeth were prepared to expose flat superficial dentinal surfaces. Each material was mixed according to the manufacturer ' s instruction ' s. A prefabricated nylon mold was applied to the exposed denton, filled with the core material, then light cured and stored in distilled water at 37°C for one hour, 24 hours and one week. The 24 hours and one week storage groups were thermocycled(5°C to 55°C) for 100 cycles before shearing, The specimen were tested with universal compression machine and the mode of failure was observed. The result showed that Vitrether core build up exhibited the greatest bond strength followed by compoglass F and then Tetrie Composite, Definite showed the lowest for all storage time. The differences among time groups were not statistically significant except for vitremer core build up and compoglass F which showed an improvement after 24 hour storage. The adhesive mode of failure revealed a combination of cohesive adhesive failure and failure for vitremer core build up and compoglass F and adhesive failure for Tetricceram and Definite composite resin

Abstract

The present study was carried out to observe the level of mercury hygiene for the dentists in Mosul city via a questionnaire given to the 98 dentists selected randomly. The data was collected and percentages were calculated. The results revealed that the dentists had some of good hygienic methods, for example, (80% of dentists were ventilate their clinic, 100% of dentists were use water cooling System during removal of old amalgam restorations), and some of unhygienic methods, for example, (33% of dentists only were uses amalgam capsules, 93% of dentists work without rubber gloves) which increase the possibility of dentists exposure to mercury toxicity. According to this results the dentists should change they manner form unhygienice type to minimize as much as possible the mercury toxicity. Seminars & lectures of continuos education are very important in this field

Abstract

This study was carried out on 900 intermediate school students aged 13-15 years from high, middle and low socioeconomic classes in the center city of Mosul in order to determine the prevalence of periodontal disease and treatment need with the three different socioeconomic levels. The CPITN (Community Periodontal Index of Treatment Needs) was used to asses the periodontal condition and treatment needs. The results showed that the disease was prevalent in 97.6% of the sample, with a slight higher percentage of students with healthy gingiva in high social class group compared to middle and low class (4%, 2% and 1.3%) respectively, but with no statistically significant difference between them. The result indicated that there was statistically significant difference in the mean number of healthy Sextants in the three groups (1.78, 1.32 and 0.91) for high, middle and low class respectively. Results also revealed a significant a healthier gingiva in females compared to males (1.55 for females and 1.12 for males). The periodontal treatment needs for the students were massive with no significant difference between the three socioeconomic level, while there are statistically significant differences between males and females,as more tales need prophylactic scaling and polishing compared to females
