The environmental impact assessment plays an important role in ensuring environmental media. This study aimed to assess the environmental pollution of the neonatal intensive care unit in Al-Jala hospital of obstetrics and gynecology, Tripoli, Libya through environmental monitoring of bacteria on different surfaces. Methods. A cross-sectional, descriptive study was carried out in the neonatal intensive care unit from December- to February 2022 at Al-Jala hospital, Tripoli. A total of 61 samples were collected with a sterile swab from high-contact environmental surfaces. Isolation, identification, and antibiotic resistance of bacterial isolated were performed by standard technique. Blood culture isolates from neonatal intensive care unit patients were compared with the environmental isolates during the study period. Results. Out of 61 samples, bacterial growth was observed in 58 samples, out of which 40 (68.9%) were gram-positive and 18 (31.03%) were gram-negative. The observed gram-positive bacterial isolate was Staphylococcus aureus 13(32.5%), and most of gram-positive isolates were recovered from an incubator, suction tip, stethoscope, ambu bag, and staff hand. The potential gram-negative bacterial isolates were E. coli 10 (55.5%), and the majority of gram-negative isolates were recovered from the door handle, suction tip, neonate breathing tube, and staff hand. The isolated bacteria were resistant to amoxicillin (41.3%), clindamycin (39.6%), imipenem, and tetracycline (27.5%). Common potential pathogens isolated from the blood culture of NICU patients were staphylococcus aureus. Conclusion. Bacterial contamination of objects and instruments in neonatal intensive care units was high (95%). This study emphasizes the need for rigorous decontamination protocols and hand hygiene. Clindamycin and tetracycline may be used for empirical therapy in clinically suspected cases of isolates.","PeriodicalId":436335,"journal":{"name":"Khalij-Libya Journal of Dental and Medical Research","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126576860","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prosthodontics clinics require a high degree of concern regarding cross-infection of patients, personnel, unsterilized instruments, and equipment. 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. Methods. 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. Results. 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. Conclusion. 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.","PeriodicalId":436335,"journal":{"name":"Khalij-Libya Journal of Dental and Medical Research","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122583953","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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. Methods. 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. Results. 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<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. Conclusion. 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.","PeriodicalId":436335,"journal":{"name":"Khalij-Libya Journal of Dental and Medical Research","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128861316","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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. Methods. 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<0.05) in this study and was analyzed using (SPSS) software, version 22. Results. 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. Conclusions. This study concluded that 1.0 mm veneer thickness was the optimum thickness regarding color matching.","PeriodicalId":436335,"journal":{"name":"Khalij-Libya Journal of Dental and Medical Research","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123651446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was conducted to evaluate and compare the effect of locator attachment and Ball-O-ring attachment on the peri-implant crestal bone level changes in edentulous patients rehabilitated with implant retained lower over denture. Methods. Twenty edentulous patients (male) were participating in this study, they were rehabilitated by mucosa supported maxillary complete denture and implant retained mandibular over denture by two implants installed in the canine region, patients were divided into two equal groups according to the type of attachment used, the locator attachment was used for group I and Ball-O-ring attachment was used for group II. Peri-implant crestal bone level changes were assessed using intra-oral radiographs taken with the standardized long cone paralleling technique using custom made acrylic template and the Rinn-xcp system. Periapical radiographs were taken every six months to complete a period of 18 months follow up period. The marginal bone loss at different intervals was obtained by calculating the difference in bone height at that interval from the base line measurement and statistically analyzed (t-test P < 0.05). Results. The result of this study showed that the time has significant effect on the mean values of the peri-implant bone height on both groups. Moreover, group I had significantly less bone resorption from insertion to twelve months in compare to group II. Conclusion. The insignificant difference observed between comparing the peri-implant bone loss between the two groups indicates that the two treatment modalities are effective for the rehabilitation of lower denture. Locator attachments have the ability to control the amount bone loss. It could be advantageous in cases where the retention of implants retained overdentures is compromised.","PeriodicalId":436335,"journal":{"name":"Khalij-Libya Journal of Dental and Medical Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129894541","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
