(2019) Alansaari, Albatool
Objectives: To assess the dental anxiety levels among patients attending Oral Surgery department at Hamdan Bin Mohammed Dental Clinics (HBMCDM) and to identify factors influencing dental anxiety level among the patients attending Oral Surgery department. Methods: A cross-sectional study using a Likert-scale questionnaire was conducted to collect quantitative data from 206 patients at the Oral Surgery Clinics at (HBMCDM). Dubai, U.A.E. Descriptive analysis as well as independent-t test and Chi-Square Test to compare and determine the associations of the dental anxiety scores between groups was carried out using IBM-SPSS for windows version 24.0 (SPSS Inc., Chicago, IL). Results: The prevalence of dental anxiety (MDAS score of 13 or more) of the 206 patients was 72.33% with overall severity represented by a mean score of 15.50 (SD ± 5.4). The maximum anxiety scores were reported for: planning to going to the dentist for treatment, sitting in the dentist’s waiting room, having a tooth drilled, having teeth scaled and polished, having a local anesthetic injection, and having an extraction/surgical procedure with the following anxiety scores respectively 2.12, 2.21, 2.70, 1.92, 3.05 and 3.50. There was a significant high dental anxiety average score among females 16.42 (SD ± 5.54) compared with that among males 14.65 (SD ± 5.16), p-value was 0.02. The average dental anxiety score increases significantly by education level (p-value 0.02). There is statistically significant difference between average dental anxiety scores among student 17.44 (SD ± 6.09) compared with the employee 14.92 (SD ± 5.34) and the unemployed 17.24 (SD ± 4.78) (p-value 0.03). However, there were no relation between dental anxiety scores and age of the patient, marital status, dental history and history of bad dental experience. The best-recorded technique to reduce patients’ dental anxiety was communication strategies (51% of the respondents) and followed by Tell-Show-Do techniques (33.0%). Conclusion: From the study, it can be concluded that dental anxiety levels among patients in United Arab Emirates was significantly high especially in relation to teeth extraction and dental surgical procedures and the least anxiety scores were reported for scaling and polishing.
The pattern of oral and maxillofacial injuries among patients attending Fujairah Hospital, Fujairah, UAE.
(2017-08) Alhmoudi, Asmaa
Objective: To determine the pattern of oral and maxillofacial injuries among patients attended Fujairah Hospital, Fujairah, UAE. Study design: Descriptive retrospective hospital based study. Study population: All patients who attended the Oral and Maxillofacial Surgery Department- Fujairah Hospital for the treatment of oral and maxillofacial injuries during the period of the study. Methodology: This is a retrospective study of patients who had attended Fujairah Hospital between 2003 till 2015, with oral and maxillofacial injuries using a structured form to obtain the relevant information. Socio-demographic information (age, gender, education level), type of injury, place where the injury took place, and the causes of injury were recorded. Clinical findings were recorded such as: type of injury, site of injury, single or multiple, soft tissue or hard tissue injury. The hard tissue injury was categorized as a fracture of nasal bone, maxilla, mandible, zygoma, frontal, palatal and orbital bones. Radiological investigations, including plain skull radiography, orthopantomograph and where necessary a computed tomography (CT) were reviewed. The treatment offered and treatment outcomes were also recorded. The data were entered into a computer data base (SPSS) version 20 for statistical analysis. An association of maxillofacial injury parameters and type of injuries was evaluated using Chi –square test. A significant level p <0.05 was used to draw out conclusions. Results: Road traffic accidents (RTA) were the most (34.8%) common causes of oral and maxillofacial injuries. The introduction of the compulsory seatbelt law has dramatically reduced the incidence of the maxillary facial injuries from 62.6% prior to the introduction of the law to 24.0% after the law introduction. Five hundred and forty-eight patients (76.4%) had sustained fractures of either the mandible, mid face or both and 335 (46.8%) patients sustained fracture mandible and 122 (17%) sustained fractured zygomatic complex including zygomatic arch, while 91 patients (12.7%) diagnosed with maxillary fracture. Surgical wound debridement and wound suturing were the most common method of treatment for soft tissue injuries, while mandibulomaxillary fixation was the most (45.3%) widely used method of treatment of bony injuries prior to 2008. Likewise, open reduction and internal fixation (ORIF) has been widely used method after 2008. Conclusion: This study showed that maxillofacial injuries in Fujairah are similar to national, regional characteristics. These findings should alert the authorities, particularly the government and the Road Safety Authority on the need for the enforcement of existing traffic laws and to raise the awareness among the public about the magnitude of the problem.
The quality of dental X-ray images that are referred to oral surgeons A multinational study in the Middle East and United Kingdom
(2017-02) Sebeeh, Taghrid
Background: The dental profession is committed to delivering the highest quality of care to each of its individual patient and applying advancements in technology and science to continually improve the oral health status of the population. Several guidelines have been developed to serve as an adjunct to the dentist’s professional judgment on how to best use diagnostic imaging for a patient. Radiographs can help the dental practitioner evaluate and definitively diagnose a number of oral diseases and conditions. However, the dentist must weigh the benefits of taking dental radiographs against the risk of exposing a patient to radiation, the effects of which accumulate from multiple sources over time. The dentist, knowing the patient’s health history and vulnerability to oral disease, is in the best position to make this judgment in the interest of the patient. Objective: The purpose of this study is to evaluate the different perceptions of what makes a proper dental X-ray image, and to compare if there is a difference in dentists’ perspectives of the quality of dental X-ray images against established criteria in the “National Radiological Protection Board (NRPB)”, between dentists in the Middle East and the dentists in the United Kingdom. Material and methods: This was a cross-sectional study of a total of 400 dentists of all specialties, who were invited to participate in a survey, using a structured questionnaire shown on a tablet screen that included 10 different X-ray images of teeth intended for extraction. These images were selected for the questionnaire by expert radiologists and oral surgery consultants from a pool of referred dental X-ray images to oral surgeon in UK. The criteria used for answering the questionnaire is an adaptation of the “National Radiological Protection Board (NRPB)” criteria which uses subjective quality rating of radiographs. The criteria included two ratings (acceptable and unacceptable) for the purpose of the extraction of a tooth. All ten images were pre-evaluated by a calibrated panel of experts composed of seven specialists in the field of maxillofacial radiology. The questionnaire also included other information obtained for the purposes of comparison and description regarding the area of specialty, years of experience, location of current practice and country of qualification in dentistry. Results: A total of 342 participants were included in the study out of 400 with a response rate of 85.5%. The inclusion criteria of the selected questionnaire depended on completion of all elements of the questions included. There were 215 (62.9 %) males and 127 (37.1 %) females. The experience in dentistry ranged from 1 year to 45 years with a mean range of experience of 13.28 years. The distribution of participants according to the place of qualification was 182 (53.7%) from the Middle-East, while 160 (46.8%) were from the United Kingdom. The average of the score of reading the ten photos correctly in agreement of the panel of experts was 4.95 (S.D. 1.62) overall in both groups of participants from the Middle East and from the United Kingdom. There is no association between the number of years of experience and the score of correct answers (p-value=0.113). This study has iv revealed that there is a significant difference in the overall correct score of the questionnaire in favour of the participants group with a qualification in dentistry from the United Kingdom (p-value= 0.013). Conclusion: The participants qualified from the United Kingdom performed better than the Eastern participants in answering the questionnaire. The perception of dentists of varying specialties in the Middle East in regards to the quality of referred dental X-ray images needs to be addressed. This perception affects the quality of care that the patients receive, through either repeated X-ray exposure or by management of patients with inadequate Xray images. More attention is needed to highlight this issue and strict protocols for the quality of referred dental X-ray images must be put in place.
