Based on the surveying of panoramic radiographs of patients attended the dental clinic. A total of 500 panoramic radiographs were screened, and all patients with impacted canines were further screened clinically and radiologically. The purpose of this study was to report the prevalence of impacted canine teeth in Sirte city according to the age, and gender. The clinician can investigate the presence and position of the canine using visual inspection, palpation, and radiography. Canine impaction with or without other impactions occurred in (6.8%) of the scanned radiographs, with higher incidence in female (79.4%) than male (20.6%) cases. The aim of the present study was to create baseline information by evaluating the prevalence of impacted canine in middle region of Libya/Sirte city.

There is limited evidence in Libya regarding UTIs and HIV. This study was conducted to determine the prevalence of UTI among HIV patients attending the infectious disease hospital in Benghazi, Libya. Urine samples are collected and processed by macroscopic and microscopic examination for the identification of bacteria. Antibiotic susceptibility testing was performed using Kirby-Bauer’s disc diffusion method. Urine samples were collected from 112 HIV seropositive patients, and 428 seronegative control group individuals. Out of 112 seropositive patients, 18(16%) had UTI. Escherichia coli was the most frequently occurring bacterial isolate 8(44%), followed by Staphylococcus aureus 4(21%), and Klebsiella species 3(17%). While the least common pathogens were Salmonella Species, Micrococcus, and Sphingo-bacterium; each had 1(6%). The age group 23-28 years recorded the highest prevalence of UTIs 11 (61%), while those aged 35-42 years had the least occurrence 2 (11%). On the other hand, out of 428 seronegative individuals' samples, 40(9%) yielded growth of bacteria. The distribution of uro-pathogens from urine specimens of seronegative patients revealed also Escherichia coli as the most prevalent uro-pathogens 18(45%), followed by Klebsiella species 8(20%) and then Staphylococcus aureus and Enterobacter species; each 5(12.5%). While the least common pathogens were Pseudomonas species and Staphylococcus Saprophyticus 2(5%). The age group 25-30 years recorded the highest prevalence of UTI; 11 (61%) in HIV-positive patients, while the age group. 41-70 years recorded the highest prevalence of UTI 18(45%) in HIV-negative patients. Female individuals showed the highest number of bacterial isolates; females had a prevalence of 14(78%) and males 4(22%) in seropositive patients, while in the seronegative patients, females had 35(87.5%) and males had 5(12.5). The study showed a high prevalence of UTIs among HIV patients which is an indication of the ineffectiveness of prophylaxis administered to HIV patients to prevent opportunistic Sat, 30 Dec 2023 00:00:00 GMT http://dspace-su.server.ly:8080/xmlui/handle/123456789/2720 2023-12-30T00:00:00Z http://dspace-su.server.ly:8080/xmlui/handle/123456789/2719 Influence of preoperative factors on the outcome of root canal treatment (Part 1): A retrospective clinical study Ehtiba, Gazala; Ehtiba, Ali Aim: The aim of this study was to evaluate the effect of preoperative prognostic variables (Gender, Age, General medical health, Tooth type, Tooth location, Pulpal and periapical status) on the outcome of the initial endodontic therapy. Material and methods: Ninety-one patients out of 109 were included and had complete medical and dental record. A total of 146 teeth received an endodontic treatment and overall 408 Canals obturated. All treatments were performed through 2018 and 2019, in a private Dental Clinic in Sirte, Libya. Two independent endodontists, who have analyzed all preoperative and postoperative radiographs. Treatment effectiveness was evaluated using the European Society of Endodontology's standards. The periapical index was used to grade the periapical state. Setting the level of significance at p ˂ 5% by applying chisquare Pearson test. Results: The initial root canal procedure had an overall success rate of 89.7%. The health status showed their power effect on success rate with 83.6% (p-value =0.0001). Periapical status had a strong effect on the outcome. Apical periodontitis (AP) was existing in 49 of all teeth, with a PAI >3 in 17 teeth. The success rate (SR) was 61.6%, 11.6%, 6.8% & 9.7% with teeth has PAI 1, PAI 2, PAI 3 and PAI >3, respectively (p-value = 0.004). However, pulpal status shows that the success rate for vital teeth was 57.5% and for nonvital teeth was 32.2%.Conclusion: Within the parameters of the investigation, medical health and periapical condition have demonstrated to be powerful significant outcome predictors Sat, 30 Dec 2023 00:00:00 GMT http://dspace-su.server.ly:8080/xmlui/handle/123456789/2719 2023-12-30T00:00:00Z http://dspace-su.server.ly:8080/xmlui/handle/123456789/2718 Common Eye Diseases in children attending Makkah eye hospital in Aden, Yemen Saleh, Reem Alkhadher; Gaffer, Ibtihal Aidroos Zain Background: Eye diseases in children are important cause of medical consultation. This study aimed to determine the distribution and spectrum of childhood eye diseases at the pediatric outpatient clinics of Makkah eye hospital in Aden. Materials and method:This is an observational retrospective study. The medical records of all patients aged 16 years or younger who were seen at the pediatric ophthalmology outpatient clinics during the year 2021, were reviewed. The following data were recorded for each patient: sex, age, residency, site of trauma, site of disease, and diagnosis. Descriptive statistics were computed for continuous and categorical variables. The statistics computed included mean and standard deviations (SD) of continuous variables and are presented as mean ± SD, frequencies and percentages of categorical factors. Results: Total study patients were 146 (males were 61.6% and females were 38.4%). Most of them 58.2% were from rural areas. Their age ranged between 1 month to 16 years and their mean age was 7.1 ± 4.1 years. Children aged ≤ 5 years were (37.7%), of the age group 6 – 10 years were (35.6%) and of the age group 11 and 16 years were (26.7%). The most common eye disorders were ocular trauma in (43.2%) children. Squint was the second commonest disease and accounted (14.4%). Congenital glaucoma found in (11.6%) children, refractive error found in (9.6%) patients, and congenital cataract in (6.9%) children. Ocular trauma was predominant (19.9%) in the age group 6-10 years, while squint was predominant (6.8%) in the age group 10-16 years old and congenital glaucoma was predominant (10.2%) in the age group ≤ 5years. The highest frequency of refractive errors were found in children aged between 6 to 10 years and children aged between 11 to 16 years, (P = 0.000). Conclusion: The most common eye diseases in our study were ocular injuries, squint, congenital glaucoma, refractive errors and congenital cataract, respectively.
