Abstract

Objective: Skin colour measurement and analysis was performed for Iraqi Kurdish population in sulaimani city. The purpose of this study was to produce a dedicated skin shade guide for precise colour reproduction and colour matching of maxillofacial prostheses with the patient’s original skin colour. Methodology: A skin colour measurement was undertaken for 140 subjects (73 female and 67 male). A method of capturing their (L* a* b*) colour values from nine body parts was performed using a Minolta CM-2600d spectrophotometer and a colour Data Software. The study sample aged between 18 to 50 years from Sulaimani city representing a Kurdish population of the north of Iraq. A comparison was made between (L* a* b*) colour values of the face and arm and between male and female shades. Data analysed using Independent-samples T-Test. Furthermore this study aimed at employing the performed data for suggesting a dedicated skin shade guide for the population examined in this study. Results: A significant difference between facial and arm colour was identified. Facial colour found to be more reddish and colourful but darker than arm colour. Furthermore, collected data showed lighter female colour than males. Variations in skin colour of the study population were detected, body area differences and gender differences found to have a significant effect on the skin colour formulation of the study population. Based on colour data obtained, a skin shade guide was suggested for the population examined in this study. Conclusions: A consistent colour shift in Kurdish population between facial and arm colour in which facial colour found to be reddish, more colourful, and darker than arm colour. Females are found to have a lighter colour than males. A dedicated skin shade guide was developed and suggested for Kurdish population based on a comprehensive colour gamut that was determined in this study.

Abstract

Introduction: Diagnosis is one of the important skills for dental students. During their clinical training dental students make diagnostic mistakes, which are expected because of limited knowledge and experience. Despite the fact that these diagnostic problems are usually addressed during the clinical training in the final two years, the exact reasons for diagnostic inaccuracies made by students have not been investigated thoroughly in Iraqi dental schools. Aim: The aim of the study is to identify factors influencing the appropriateness of diagnostic procedure by students performing dental extraction. Material and methods: Eight Selected items from the case sheet of the Department of Oral Surgery were used to evaluate the student’s accuracy of surgical diagnosis. Seventy eight dental students were included in the study. After completion of surgical (dental extraction) procedure, each student was asked about the reason behind the diagnosis. Results: Documentation of selected items reported as follows: chief Complaint (CC) field was neglected in 9%; history of present illness has been neglected in 73 case sheets (93.6%). Chi square test, however, showed no significant relationship between history taking (CC and HPI) and the accuracy of diagnosis. Extraoral clinical examination included lymph node (LN) examination, which was reported in 42 cases (53.8%); and facial swelling, which has been reported in 45 (57.7) cases. Intra oral examination items reported as follows: cavity probing was documented in 33 (42.3%) cases; tooth percussion for tenderness documented in 50 (64.1%) cases; examination for tooth supporting structure reported in 46 (59%) cases. Chi Square Test did not show significant relationship between both extra and intra oral examination and the accuracy of diagnosis (p>0.05, df=12). 56 students, however, made their diagnosis by guess rather than accurate diagnosis process. How about the differences you observed by gender? Conclusion: There is an obvious lack of documentation in both history taking and clinical examination. This might negatively influence proper diagnostic procedure.

Abstract

Introduction: Distal caries of mandibular second molars has been documented to be associated almost exclusively with impacted third molars. The level of involvement of second molars in distal caries is influenced by the angulation of the occlusal surface of mandibular third molars and third molars depth. In spite of the importance of these factors on the occurrence of distal caries, their influence on prophylactic extraction decision of asymptomatic impacted molars for Iraqi population did not get enough attention. Aim: of the study: To determine the influence of mandibular third molar impaction, as identified by panoramic radiograph, on distal caries incidence in second molar in Iraqi population. Materials and Methods: Panoramic radiographs of impacted mandibular third molars prior to surgical extraction were retrieved from the database of Al-Karamah Secondary Dental Care Centre in the period 2004-2013. Demographic data were collected for all cases. Each panoramic radiograph was examined for the presence of distal caries of mandibular second molar and for the level of depth and degree of angulation of adjacent impacted mandibular third molar. Results: One hundred forty-eight panoramic radiographs of 214 pre-surgically extracted impacted mandibular third molars were reviewed. Eighty-four (56.8%) of the cases were for males and sixty-four (43.2%) were for females. ChiSquare Test showed significant relationship between age group, impaction angulation, impaction depth and incidence of mandibular second molar distal caries. It also showed highly significant relationship between angulation and depth of impaction. Conclusion: Horizontally impacted mandibular third molars close to the level of occlusion increases the chance of distal caries incidence in adjacent mandibular second molars. Close monitoring for such cases would be a suitable option. Further prospective studies should be conducted to study the influence of other factors on distal caries incidence.

Abstract

Background: Acid etching of enamel appears to improve retention by selectively eroding certain hydroxyapatite formations and facilitating penetration by the development of resin tags. Aim of study: To evaluate shear bond strength (SBS) of flowable composite to non-lased and lased groups, compare the (SBS) of flowable composite between Total and Self-etch in non-lased and lased groups, and failure mode analysis.Materials and Methods: Forty bovine incisors were used, enamel surfaces was grounded by silicon carbide paper and samples were randomly assigned into two main groups (Group A: Non lased n=20, Group B: lased prepared n=20). Each main group was subdivided randomly according to the adhesive systems that used which are: total-etch adhesive and self-etch adhesive, which were applied to the prepared enamel surface according to manufacture instruction. Composite rod applied over the bonded area and cured. Samples were stored in distilled water at 370 for 24 hours. The evaluation of shear bond strength was employed by the use of universal testing machine. Results: The results of Student’s t-test showed that there was no significant difference between the lased and non-lased enamel groups (P= 0.311). One–way ANOVA test and Duncan's Multiple Range test that compare shear bond strength between total and self-etch adhesives showed no significant difference in both lased and non-lased enamel groups. Conclusion: The mean shear bond strength and enamel surface etching obtained with an Er,Cr:YSGG laser was not comparable to that obtained with non- lased enamel surface.

Abstract

Introduction: Laser application in dentistry is the latest innovative modality which has been used in different dental and surgical fields. Among the different types of lasers, the Er:YAG laser is used for soft tissue surgery in numerous ways. Methods: Forty five patients, who had various oral conditions, were referred to the Department of Oral and Maxillofacial Surgery in Alwasity teaching hospital and selected to be treated by Er:YAG Laser. The subjects were divided into six groups based on the clinical diagnosis. Group1 for 17 subjects with polyps, Group2 for 6 subjects requiring implant exposure, Group3 for 16 subjects requiring frenectomy, Group4 for 1 apicectomy, Group5 for 2 subjects with aphthous ulceration and Group6 for 3 subjects with pyogenic granuloma. Results:. Our study confirmed that soft and hard tissue surgery by Er: YAG laser had less oedema, post-operative bleeding and pain, good cutting and coagulation effects, easily tolerated and rapid uncomplicated healing processes in comparison to the conventional surgical methods of treatment. Conclusion: With laser surgery, treatment times and post-operative healing periods are much shorter. Using Er: YAG lasers in soft-tissue surgery means that sutures are rarely needed, and with the laser’s simultaneous disinfection effects, healing is faster with fewer post-operative complications.

Abstract

Aims: To evaluate and compare the fracture resistance of maxillary central incisors received EverStick adaptable glass fiber reinforced composite posts and prefabricated glass fiber Luxa post and to determine the mode of failure. Materials and Methods: Thirty extracted human permanent maxillary central incisor were decoronated, instrumented, and obturated. Post space was prepared in each root, randomly divided into 3 groups (n=10). Group (A): Control group; the roots remained without post space preparation. Group (B): The roots prepared to receive prefabricated translucent glass fiber posts (Luxa post). Group (C): The roots prepared to receive adaptable EverStick fiber reinforced composite post. After core built up, the specimens were thermocycled, mounted in a customized metal ring and fracture resistance was tested in a Universal Testing Machine. Data collected were analyzed statistically and the mode of failures was analyzed under stereomicroscope. Results: Statistical analysis revealed highly significant difference at p≤ 0.001. Group (C) showed the highest mean of fracture resistance followed by Group (B). While Group (A) the control group show the lowest mean of fracture resistance. Fracture pattern indicated that specimens in Group: C represent 100 % favorable failure, followed by group: B which represent 80 % favorable failure, while the control group showed 80 % unfavorable failure. Conclusions: EverStick adaptable glass fiber reinforced composite post showed significantly more predictable fracture resistance than prefabricated glass fiber Luxa post.
