[CROSS-CULTURAL ADAPTATION, AND Quality In the French VERSION OF THE UPPER Branch Useful List (ULFI-I)].
This study aimed to investigate the prevalence of partial edentulism, RPD type, design, and components and their frequency of use by patients at the prosthodontic clinics of the College of Dentistry, Imam Abdulrahman Bin Faisal University, Dammam, Saudi Arabia. The prepared surveys, laboratory authorization forms, and images of the RPD metal frameworks on casts were used for data collection. Two calibrated investigators studied the digital photographs to identify the Kennedy classification, type of RPD, major connector, clasp assembly, and other details. Data was collected and analyzed statistically. The results showed that the most common class of partial edentulism was Kennedy class I, whereas class IV was the least (p  less then  0.001). Sixty two percent of fabricated RPDs had metal frameworks, whereas 37.2% were frameless. RPI was the most frequently used clasp assembly (38.9%), a significant finding in Kennedy class I(p  less then  0.01). The maxillary anteroposterior palatal strap and mandibular lingual plate were the most commonly used major connectors, at 41.2% and 60.8%, respectively. Conclusions Simple RPD design that accomplishes the treatment objectives as well as proper communication with a well-trained dental technician would promote the success of RPDs. © 2019 The Authors.Purpose This study evaluated the extent of bacterial contamination in water from dental unit waterlines (DUWLs). Methodology Water samples were collected (before flushing, 1 min post-flushing, and 3 min post-flushing) from 24 clinics (Group A no disinfection, Group B citric acid disinfectant) of a Government Dental College. Bacterial counts, identification, antibiotic sensitivity tests, determination of endotoxin levels, and scanning electron microscopy (to confirm the presence of biofilm) were performed. Results The most common opportunistic bacteria were P. aeruginosa (95%), S. aureus (58%), S. auricularis (49%), P. fluorescens (44%), and A. baumannii (20%). Approximately 50% of the bacterial isolates were resistant to two or more antibiotics. Flushing for 3 min did not reduce the contamination of water from Group A clinics which exceeded the recommendation of ≤500 CFU/ml. No bacterial growth was seen in Group B samples. Endotoxin levels were >5.00 endotoxin units (EU)/ml in Group A and ranged from 1.33 to 5.00 EU/ml in Group B clinics. Scanning electron microscopy images showed bacterial biofilms on the surfaces of the tubes. Conclusions DUWL contamination is a serious issue in dentistry, and the microbiological quality of the water must be monitored regularly. Further studies on endotoxin exposure and prevention are therefore necessary. © 2019 The Authors.Objectives Maxillofacial trauma (MFT) is a serious health problem and in Saudi Arabia is mainly caused by road traffic accidents (RTAs). MFT commonly associated with injuries to the face, head, and jaws and may cause soft tissue lacerations and bruises. MFT can also cause fatal blood loss and airway obstruction. The objective of this review was to determine the prevalence of MFT, identify the major causative factors in males and females in the main cities of Saudi Arabia. LGH447 Materials and methods We performed literature searches of all published studies describing MFT from KSA during the last 20 years. Results In Saudi Arabia, males are more prone to MFT than females, although the male female ratio of MFT varies between different cities. Specifically, Aseer has the highest male female ratio (101), followed by AlHofuf (8.31) while AlQurayyat had the least gender ratios of MFT (21). Most cases of MFT are associated with RTAs, which accounted for (63%-90.3%) in Medina, (89.1%) in Aseer, (86.1% -87.1%) in Riyadh, (67%-73.1%) in Jeddah, (71%) in Khamis Mushait, (64.2%) in Makkah and (63.3%) in Al-Hofuf. The least percentage of RTA resulting into MFT was recorded in AlQurayyat (24%). Conclusion Maxillofacial trauma is a serious health problem in Saudi Arabia. RTAs remain the major cause of maxillofacial injuries especially among males, thus strict implementation of traffic rules is a must to minimize maxillofacial injuries and its physical and psychological impact. © 2019 The Authors.Objectives Tooth surface loss (TSL) or tooth wear (TW) is an irreversible loss of hard tooth structure caused by factors other than those responsible for dental caries. TSL is observed clinically as attrition, abrasion, abfraction, and erosion. It may be associated with symptoms such as tooth hypersensitivity and function impairment, and may lead to change in the morphology of the affected tooth. However, it may also be asymptomatic, meaning the patient may not be aware of it. In this instance, the dentist is encouraged to make the patient aware of this issue.The aim of this review is to provide an overview of the classification and management of TSL. Material and methods The PubMed (MEDLINE) search engine was used to gather the most recent information on TSL. The search was restricted to a five year period (1 September 2014-31 August 2019), and only English-language studies were included. A Boolean search of the PubMed dataset was implemented to combine a range of keywords (Tooth surface loss OR tooth wear) AND (tooth attrition OR tooth Abrasion OR tooth erosion OR tooth abfraction OR non-carious cervical lesions) AND (humans). Studies were also obtained by manual searches and from Google Scholar. Results By this process, 560 articles and studies were obtained. More studies were also obtained by manual searches and from Google Scholar. The most relevant published studies were chosen and used in the current review. The selected articles are included in the reference list. Conclusion TSL is a clinical problem that dentists face on a daily basis. Therefore, a sound clinical approach by which TSL can be prevented and managed is essential. While this approach requires that dentists are knowledgeable about the issue, increasing public awareness of TSL is also vital. © 2019 Production and hosting by Elsevier B.V. on behalf of King Saud University.Introduction Clavicle fractures account for approximately 10% of all fractures in multiply injured patients. Our study aims to determine factors associated with surgical fixation of the clavicle fracture in multiply injured patients. Methods Major adult trauma patients from 2005 to 2014 with a clavicle fracture were included. Multivariate analysis was undertaken to determine the variables associated with fixation. Results 1779 patients (median age of 47 and a median Injury Severity Score of 17) were included. 273 (15%) patients underwent clavicle fixation. Factors associated with surgical fixation of the clavicle included year, younger age, ICU admission, or an associated humerus or scapula fracture. © 2020 Professor P K Surendran Memorial Education Foundation.
