This in vitro study was to evaluate the effect of three type provisional restorative material on micromovement of immediate loading implant. <strong>Methods</strong>. Thirty samples of provisional bridges were fabricated using three different restorative materials A- Resinous CAD/ CAM. B- Dual cure composite .C- Conventional heat cure resin, fixed-fixed bridge cemented over implant by zinc oxide eugenol free based temporally cement. All samples were mounted in a computer-controlled materials testing machine with a loaded up to50N ,100N,150N,200N and data were recorded using computer software. Vertical displacement was measurement by using the image analysis software. <strong>Results</strong>. It was found that heat cure acrylic resin group recorded statistically significant highest (p&lt;0.05), µ -movement mean value (75.70±7.615 µm) followed by dual cure composite group (53.15±5.330 µm). While, CAD/CAM resin group recorded statistically significant (p&lt;0.05) lowest µ -movement mean value (39.66±3.325 µm) as indicated by ANOVA test followed by pair –wise Tuke's tests. <strong>Conclusion</strong>. Ceramill Temp (acrylic resin) implant supported bridges showed the lowest vertical micromovement compared to composite resin and heat cure acrylic resin provisional restorations.</p> Abdesalam Sougei, Mohamed Zeglam, Wesam Eddlali, Derar Almalhouf Copyright (c) 2022 Khalij-Libya Journal of Dental and Medical Research https://creativecommons.org/licenses/by-nc/4.0 http://journals.khalijedental.com.ly/index.php/ojs/article/view/37 Mon, 13 Jun 2022 00:00:00 +0000 Assessment of Color Difference of Translucent Zirconia Substructure Veneered Using a Layering Technique with Two Different Veneering Thicknesses: An in-vitro study http://journals.khalijedental.com.ly/index.php/ojs/article/view/38 <p><strong>Background and objectives.</strong> The introduction of zirconia to the dental field created a path for development of new designs and applications, but still, a minimum framework thickness of 0.5 mm with the remaining thickness of the restoration used for building the ceramic veneer was always recommended. This might have possibly affected the final shade of the restoration due to the whitish color of Y-TZP. This in vitro study was designed to assess the color difference of translucent zirconia substructure veneered using a traditional layering technique with two different veneering thicknesses. <strong>Methods</strong>. A total of twenty translucent Ice zirconia disc samples with standardized dimensions 12 mm in a diameter, 0.5mm in thickness were designed and constructed using zirkonzahn system. The samples were classified into two groups: Group I: (n = 10) veneered by 0.5 mm thickness layering technique using IPS emax Ceram dentin shade A2. Group II (n = 10) veneered by 1 mm thickness layering technique using IPS emax Ceram dentin shade A2. Twenty composite resin discs 12mm in diameter and 5mm in thickness in A3 shade, were fabricated to be bonded to ceramic specimens using Dual-curing translucent rely X Unicem automix Self-Adhesive Resin luting cement. Spectrophotometer was used to measure color parameters L*, a*, b* for all samples. ΔE values were measured to determine color differences between the specimens and the A2 VITA classical shade (target shade). ΔE values were compared with an acceptability threshold (ΔE=3.7). Independent t-test was used to analyze data (P&lt;0.05) in this study and was analyzed using (SPSS) software, version 22. <strong>Results</strong>. The results showed that veneering thicknesses had a significant effect on the mean (ΔE) Values at P ≤ 0.001. The 0.5 mm veneer thickness showed the higher significant mean color difference (∆E) than the 1.0 mm veneering thickness where the recorded mean (ΔE) Values were (4.15±1.31) (2.65±1.39) respectively at p ≤ 0.001. <strong>Conclusions</strong>. This study concluded that 1.0 mm veneer thickness was the optimum thickness regarding color matching.</p> Noora Berhaim, Nourelhouda Misurati, Milad Eshah, Mohamed Zeglam, Hager Ashiki Copyright (c) 2022 Khalij-Libya Journal of Dental and Medical Research https://creativecommons.org/licenses/by-nc/4.0 http://journals.khalijedental.com.ly/index.php/ojs/article/view/38 Thu, 14 Jul 2022 00:00:00 +0000 Oxygen Saturation During Dental Surgery with Local Anesthesia Alone and in Combination with Sedation in Medically Compromised Patients http://journals.khalijedental.com.ly/index.php/ojs/article/view/39 <p><strong>Objective</strong>. The aim of this study was to determine which specific operative events are associated with change in SaO2 and blood pressure and heart rate in patients undergoing exodontia or minor oral surgery with local anaesthetic Medically compromised patients with Local anaesthesia alone or in combination with sedation. <strong>Methods</strong>. Arterial oxygen saturation (SaO2) with Heart rate and blood pressure was measured in 60 patients divided into two equal groups. Group I consisted of 30 patients receiving LA alone and undergoing simple extraction minor oral surgery, group II 30 patients receiving LA with oral midazolam and undergoing simple extraction or minor oral surgery. <strong>Results</strong>. There was a decrease in SaO2 from the baseline in 10% of group I patients, represented in 3 patients, 2 of them asthmatic and one anxious patient who the BP and HR raised slightly during LA admiration. There was a fall in SaO2 from the baseline in 53% of patients in group II, represented in 16 patients, the majority of them asthmatic and anxious patients, 6 patients with history of ischemic heart disease. The majority of these decreases in SaO2 or raining in BP or HR were associated with breath holding, in response to fear or emotional stress, during administration of LA due to vasoconstrictor effect or during elevation of teeth. The patients in group II showed a significantly (P&lt;0. 001) greater maximum decrease in SaO2 from the baseline value compared to group I. The length of the operating time was longer in group II than that in group I, and the patients of group II were more anxious than the patients in group I. <strong>Conclusion</strong>. It was concluded that during simple extraction and minor oral surgery under LA alone or in combination with sedation procedures such as elevation of the tooth or administration of the LA may as a result of Breath holding cause reduction in SaO2 or raising in BP or HR. In fit patients this may be of little consequence, however patients with existing airway disease or Medically compromised patients may suffer significant falls in SaO2 or alter the Blood Pressure and Heart Rate. Therefor Monitoring of vital signs and oxygen saturation recommended during simple extraction dental surgery procedure and sedation as premedication for cardiac patients would be recommended.</p> <p>Citation: Hilal M, Ajanan N.

Prosthodontics treatment undertaken in the clinics should be supplemented by the laboratory, and hence cross-infection chances have to be halted on both the fronts. The aim of this study was to evaluate attitudes regarding infection control procedures in prosthodontics clinics among general dentists, and specialists in Tripoli, Libya. <strong>Methods</strong>. A questionnaire of 11 questions was created and randomly distributed to 150 general dentists and specialists working in Tripoli's private clinics and public health centers. The questionnaire was anonymous and consisted of questions related to vaccination status, attitude and awareness towards infection control in prosthodontics clinics. Out of which (123) questionnaires were filled, giving a response rate of 82%. The data were sorted, checked, tabulated, and statistically analyzed. <strong>Results</strong>. A total of 123 dentists (68.3%) were general practitioners and (31.7%) were specialists, (39.9%) were males, and (60.1%) were females. In this study there was a positive correlation between vaccination status and the qualification (P =0.044). As (89.7%) of the specialists stated that they had been vaccinated against Hepatitis B virus, while only (73.8%) of general dentists had been vaccinated. The study also showed statistical significance when qualification was cross‑tabulated against the responses for various questions, that is, disinfection of rubber bowl (P = 0.027), sterilization of dental cast (P = 0.032), sterilization of metal framework (P =0.009), bite registration and bite block sterilization before sending to the dental laboratory (P =0.005), custom trays sterilization (P =0.005), and sterilization of the handpiece between cases (P = 0.000). The study also revealed that while just 11.9% of general dentists disinfect the impression prior to sending it to the dental laboratory, 23.1% of specialists do so after rinsing the impression. <strong>Conclusion</strong>. The findings of this study suggest that there are insufficient attitudes toward infection control procedures in prosthodontics practice. Furthermore, the implementation of selective standard precautions, such as hand hygiene compliance, was widely practiced by the Tripoli dentists surveyed.</p> <p><strong>Citation</strong>: Misurati N, Berhaim N, Traina H.

This study also aims to evaluate the impact of self-assessed brushing frequency and the role of parental observation during brushing on DMFT scores. <strong>Methods</strong>. a cross-sectional study was carried out on 185 schoolchildren (125 boys and 60 girls) between the ages of 12-14 years in Tripoli to collect the data for decayed, missing and filled teeth in the permanent teeth (DMFT). TNI, CI, RI and FMI were determined. The impact of brushing frequency and parental observation during brushing on the DMFT score were assessed within the stated age range. Data were analyzed using GraphPad Prism version 9. <strong>Results</strong>. high rates of treatment needs were observed amongst girls (66%) and boys (55%), with no statistically significant difference. CI was found to be 6.8 and 4.6 for boys and girls, respectively, whereas RI was shown to be 0.08 and 0.05, for boys and girls, respectively. FMI was found to be 0.9 amongst both genders. Brushing frequency was correlated with DMFT scores. In contrast, the role of parents in encouraging oral hygiene habits did not impact oral health status. <strong>Conclusion</strong>. The study indicated unmet treatment needs for dental caries and little experience of restorative treatment. Oral hygiene education for children and parents needs to be implemented to maximize opportunities for oral health improvement.</p> <p><strong>Citation</strong>: Misurati N, Berhaim N, Traina H.

The purpose of this in vitro study was to evaluate the fracture resistance of endodontically treated teeth that were prosthetically restored with two fiber post Surface characteristics with different lengths (8,10 and 12mm). <strong>Material and methods.</strong> A total of thirty intact upper central incisors were collected and decoronated 2mm above to the cemento –enamel junction. Then prepared with 2mm a circumferential ferrule and a chamfer finish line of 0.5 mm. The teeth were embedded in epoxy resin blocks using a centralizing device. Root canals were performed then post holes were prepared with the corresponding drill using the drilling machine. The thirty samples were divided into 2 main groups according to the post surface characteristics Group І: parallel smooth glass fiber post. (n=15). Group ІІ: parallel serrated glass fiber post. (n=15). The samples of each group were further subdivided into three sub-groups(n=5) according to different post lengths as follows: Sub Group A: 8mm length. Sub Group B: 10 mm length. Sub Group C:12mm length. All posts were cemented with a-self-adhesive resin cement using a load applicator device. Metal crown coping was constructed and cemented to the post and core assembly. Each specimen was then subjected to a compressive test in a universal testing machine where load was applied on palatal side at angle of 135 degrees in relation to long axis of the root at across head speed of 1mm/min until failure occurred. <strong>Results</strong>. There was no statistically significant difference between the tested post Surface characteristics, and there was a statistically significant difference between the three post lengths. <strong>Conclusion</strong>. The increased in post length showed significant increase fracture resistance of endodontically treated maxillary central incisor teeth, while Surface characteristics of post showed non-significant influence to fracture resistance.</p> <p><strong>Citation</strong>: Elkawash H, Eshah M.
