The purpose of the present paper is to present the results of central corneal thickness &amp; intraocular pressure measurements in diabetic patients with or without retinopathy, and compare the results with non-diabetic control patients. Methods. Total number was 152 patients were 152 eyes The study group was divided into 3 groups as following: 50 non diabetic (control). 50 diabetic type II with no diabetic retinopathy. 52 diabetic type II patient with diabetic retinopathy. Correlation analysis was performed to assess the association between glycosylated hemoglobin levels&amp; Intraocular pressures and retinal changes among subgroups. Results. Demographic characteristics of study and control groups were similar (P&gt;0.05). Mean CCT 553.62 with Std deviation (14.47) in control cases and 622.27 with Std deviation (507.09) in diabetic cases which is more than control however the distinction failed to reach applied math significance were (p value= &gt; 0.05). additionally, CCT and diabetic retinopathy association was significant were CCT in diabetic patients with no retinal changes was 563.96 Std deviation (18.85) and in diabetic patients with retinopathy was 670.45 Std deviation (717.2) and P value = 0.004 (significant). There was significant correlation between increased corneal thickness and intraocular pressure were p-value = 0.002. Conclusions. We found that the central cornea of diabetic patients is thicker when compared with non-diabetic patients. Thicker central cornea associated with diabetes mellitus should be taken into consideration while obtaining accurate intraocular pressure measurements in diabetics.</p> Yasmena Abdulhadi Suliman Masuod Wafa Lareibi Mohamed Eldursi Copyright (c) 2021 Khalij-Libya Journal of Dental and Medical Research https://creativecommons.org/licenses/by-nc/4.0 2021-11-21 2021-11-21 6 1 1 5 Shaping Ability of Three Ni-Ti Rotary Systems in Curved Root Canals of Extracted Teeth http://journals.khalijedental.com.ly/index.php/ojs/article/view/22 <p>Aims. The purpose of this study was to compare the effects of 3 different rotary Ni-Ti instruments used to prepare curved root canals on the root canal curvature by using Digora system. Methods. Mesiobuccal canals of 30 mandibular first molars with curvature between 20-40 degrees were divided into 3 equal groups according to Ni-Ti rotary system need for root canal preparation: Alpha, RaCe and ProTaper system. Root canal curvatures from both buccal and proximal view were measured before and after instrumentation by using Digora system and image analysis software according Schneider's technique. Results. The result indicated that ProTaper system showed significantly greater decrease in curvature in the mesio-distal view and in the bucco-lingual view (p&lt;.05). Conclusion. The current study concluded that the rotary Ni-Ti RaCe system better maintained the original root canal curvature than the rotary Ni-Ti Alpha System and ProTaper Universal Systems. It may be better to use the rotary Ni-Ti RaCe system to prepared curved canal in order to maintained the original root canal curvature.</p> Showg Salem Nora Agila Salaheddin Alkesher Copyright (c) 2021 Khalij-Libya Journal of Dental and Medical Research https://creativecommons.org/licenses/by-nc/4.0 2021-11-27 2021-11-27 6 1 6 10 Ultra-High-Molecular-Weight-Polyethylene (UHMWPE) as Desired Polymer Material for Biomedical http://journals.khalijedental.com.ly/index.php/ojs/article/view/24 <p>It is very important that any materials used as implant material work in harmony with the body. There will be drawback with every material. No matter how good, as nothing can be 100% identical as the natural human tissue. The body operates in an environment at a constant temperature of 37°C and pH of 7.25, so choice of materials will have to withstand these conditions. Incorrect use of material can cause rejection by the body, infection and even cancer, leading to more pain and discomfort by the patient. In turn the possibility of even further damage to the joint. The implant must work in the same way as the body part it is replacing- clear understanding of how the joint works is needed. Ultrahigh molecular weight polyethylene is considered as the standard material for Artificial joints to decrease the total weight and the wear rate to make it more flexible. This is what makes Ultra-High-Molecular-Weight-Polyethylene (UHMWPE) such an appropriate polymer. It is very widely used in total hip and knee joint replacements having the highest known impact strength of any thermoplastic presently made, can highly withstand abrasion, and has a very low coefficient of friction. Therefore, these properties, connected with extremely low moisture absorption, make UHMWPE especial material for the medical industry due to good industrial impact and wear resistance sliding applications. For moving joints, the friction would be damaging without the natural lubrication. In implant components this does not exist, however UHMWPE is self-lubricating, making it ideal for component such as an acetabular cup, which would wrap around a metallic femoral head in a hip joint. Also, UHMWPE has high impact strength, high toughness, and low elastic modulus, but it has disadvantages such as low tensile, transverse and compressive strengths with high creep rate. This review article deals with the history of UHMWPE, its material properties that make it an ideal candidate for total joints, implant-component fabrication procedures and provides insights as to why some of the implants eventually fail.</p> Assma Said Copyright (c) 2021 Khalij-Libya Journal of Dental and Medical Research https://creativecommons.org/licenses/by-nc/4.0 2021-12-05 2021-12-05 6 1 11 16 Tooth Loss and Prosthesis Replacement at El-Koms City http://journals.khalijedental.com.ly/index.php/ojs/article/view/25 <p>Background and objective. Loss of at least one tooth disturbs the structural balance of the remaining natural teeth and may result in widening of proximal contacts, and other deformities.The proportion of full and partial edentulous people, as well as their prosthetic therapy, were investigated El-Koms city Methods. Patient demographics, the percentage of partial and completely edentulous patients, and their prosthetic treatment were collected at four dental clinics. Health services. Ministry of Health in El-Koms city. The study was approved by the prosthodontics department, Faculty of Dentistry, University of Al Marqab. In 2020, a total of 1000 people were assessed in four dental clinics, with 472 individuals being chosen as part of the sample study group. Patients were chosen based on their age, which ranged from 25 to 75 years old, and their dental records.</p> Hussein Abuzgyaia Copyright (c) 2021 Khalij-Libya Journal of Dental and Medical Research https://creativecommons.org/licenses/by-nc/4.0 2022-01-01 2022-01-01 6 1 17 23 Anatomical Causes of Infertility Diagnosed Using Imaging Tests in A Group of 100 Women http://journals.khalijedental.com.ly/index.php/ojs/article/view/27 <p>Background and aims. The demographics of infertility differ dramatically from one region to another. Therefore, details about the causes and distribution of infertility of different localities and regions are essential for any effective management strategy. This study aimed to evaluate the distribution of the causes of infertility in a women population attending a tertiary healthcare facility. Methods. A cross-sectional observational study conducted in a gynecology clinic on female patients who came for infertility consultation or treatment between June -2019 and December-2020. The cause of infertility was diagnosed by the history, examination and investigation. Data were arranged in tables, and the frequency of each factor was calculated and therefore the prevalence was estimated using SPSS 25. Results. secondary infertility (53%) was more prevalent than primary infertility (47%). Pelvic inflammatory disease was the leading cause (40%) and it was associated with tubal factor infertility. Second cause was polycystic ovarian syndrome (PCOS) (33%). Infertility causes changed as the age of marriage increased. In females married for less than 5 years, PCOs was the main cause of infertility. Conclusion. Causes of infertility in women change according to the age group and the age of marriage. This study shows that PID is the most common cause of infertility in females followed by PCO. A significant association between infections and tubal factor infertility was found.</p> Basma Taryna Copyright (c) 2021 Khalij-Libya Journal of Dental and Medical Research https://creativecommons.org/licenses/by-nc/4.0 2022-01-04 2022-01-04 6 1 24 30 Effect of Nonsurgical Periodontal Therapy On IL-36 Levels in Serum, Gingival Crevicular Fluid of Type 2 Diabetic and Non-Diabetic Patients with Chronic Periodontitis http://journals.khalijedental.com.ly/index.php/ojs/article/view/28 <p>Objective: The aim of this study was to compare the level of inflammatory marker IL-36β in serum and gingival crevicular fluid in type 2 diabetic and non-diabetic patients with chronic periodontitis, before and after phase I therapy. Methods: A total of fifty subjects was included in this study; 20 Type 2 diabetic subjects with chronic periodontitis (group I) and 20 systemically healthy subjects with chronic periodontitis (group II) in addition to 10 systemically healthy subjects with clinically healthy gingiva as a control group (group III). The nonsurgical periodontal therapy was done to both group I and group II. Periodontal parameters, including plaque index, gingival index, bleeding on probing, probing depth and the clinical attachment level, in all the sites were recorded. GCF and serum were collected from all individuals included in the study; the first sample was collected from all groups (study and control) before phase I therapy. The second sample was collected 6 weeks after phase I therapy from group I&amp; group II. Levels of IL-36β in GCF and serum were quantified using ELISA. Results. The current results showed statistically significant reduction in total level of IL-36β in serum and GCF in both groups; Type 2 diabetes with chronic periodontitis group (I) and systemically healthy with periodontitis group (II) after phase I therapy. Results also showed all clinical parameters were significantly improved after the phase I periodontal therapy in both groups I &amp;II (p&lt;0.001). Conclusions. Scaling and root planning (SRP) is the mainstay of treatment of periodontal diseases as SRP was effective in improving clinical parameters in diabetic and non-diabetic patients with chronic periodontitis. IL-36β could be used as a potential diagnostic marker for periodontal disease activity in both serum and gingival crevicular fluid.</p> Hana Albashir Copyright (c) 2021 Khalij-Libya Journal of Dental and Medical Research https://creativecommons.org/licenses/by-nc/4.0 2022-01-11 2022-01-11 6 1 31 34
