Antibiotic prescribing practices by dentists: a review

Najla Dar-Odeh; Osama Abu-Hammad; Mahmoud K. AL-Omiri; Ameen Khraisat; Asem A. Shehabi

Antibiotics are prescribed by dentists for treatment as well as prevention of infection. Indications for the use of systemic antibiotics in dentistry are limited, since most dental and periodontal diseases are best managed by operative intervention and oral hygiene measures. However, the literature provides evidence of inadequate prescribing practices by dentists, due to a number of factors ranging from inadequate knowledge to social factors. Here we review studies that investigated the pattern of antibiotic use by dentists worldwide. The main defects in the knowledge of antibiotic prescribing are outlined. The main conclusion is that, unfortunately, the prescribing practices of dentists are inadequate and this is manifested by over-prescribing. Recommendations to improve antibiotic prescribing practices are presented in an attempt to curb the increasing incidence of antibiotic resistance and other side effects of antibiotic abuse.

INTRODUCTION Posts have been used efficiently to retain restorations for badly destructed teeth. This article critically analyzes the concerned topics related to the fracture resistance of teeth restored with dowel-retained restorations. METHODS A systematic review of PubMed/MEDLINE, Cochrane, and Scopus databases was completed (from 1960 to 2010). Single or combined key words were used to obtain the most possible comprehensive list of articles. Checking the references of the relevant obtained sources completed the review along with a manual search to locate related articles on the topic. In vivo and ex vivo (laboratory, computer-based finite element, and photoelastic stress analysis studies) investigations related to the topic were included. RESULTS Many factors have been proposed to influence the fracture resistance of post-restored teeth. Recognizing the significance of these factors on the fracture resistance of teeth would aid in choosing the suitable treatment modality for every individual case. Fracture resistance was improved if tooth structure loss was limited, a ferrule was obtained, a post with similar physical properties to natural dentine was used, and adhesive techniques for post luting and coronal restoration were used. Adhesively luted resin/fiber posts with composite cores appear to be the best currently available option in terms of tooth fracture and biomechanical behaviour. CONCLUSIONS Most guidelines were based mainly on ex vivo studies and to a lesser extent on limited in vivo studies. The lack of long-term controlled randomized clinical studies was the main hindrance to reaching a conclusive and undisputable opinion regarding endodontic posts in terms of tooth fracture and biomechanical behaviour.

Narghile smoking and its adverse health consequences: a literature review.

Najla Dar-Odeh; Osama Abu-Hammad

Oral squamous cell carcinoma (OSCC) is a world health problem with approximately 50% of patients having a 5-year survival rate. A change in the demographics of the disease is now being recognised, particularly in Europe, where it is increasingly being seen in young males. While a variety of risk factors are important in OSCC, it is tobacco that plays a central part in the pathogenesis of the disease. Narghile is an old form of tobacco use but in the past decade, there has been a resurgence in this form of smoking. The practice is particularly common in young males and females from the Middle East but with the advent of immigration and globalisation, its use is becoming more widespread. It is now not uncommon to see narghile smoking in western countries such as the UK and USA. Studies describing the oral effects of narghile are unfortunately scarce. While adverse effects such as periodontal bone loss and dry socket have been described, its association with OSCC cannot be excluded. Variation in the type of narghile, the type of tobacco and the presence of co-factors such as cigarette smoking may all influence clinical outcome. In the present study, the practice of narghile smoking is reviewed in terms of its effect on health, particularly oral health. The association of narghile smoking and adverse effects on the orofacial region will be outlined, namely, periodontal disease, potentially malignant lesions and oral cancer.

The changing trends in tobacco smoking for young Arab women; narghile, an old habit with a liberal attitude

Najla Dar-Odeh; Osama Abu-Hammad

Narghile smoking by young females is becoming more acceptable than cigarettes in the conservative societies of Arab countries. Lack of social constraints on narghile smoking has resulted in an increased prevalence of narghile smoking among young Arab females and an earlier age of onset of this habit when compared to cigarette smoking.Documented health hazards of narghile smoking including pulmonary, cardiovascular and neoplastic ailments are consequently expected to affect this vulnerable sector of the population together with their offspring. In this commentary, we shed some light on the changing trend of tobacco use among young Arabic women as shown by an increasing number of studies investigating habits of tobacco use in young people.

Objectives: The aim of this study was to analyze clinical records of dental patients attending the Dental Department at the University of Jordan Hospital: a teaching hospital in Jordan. Analysis aimed at determining whether dental specialists properly documented the drug prescriptions and local anesthetic injections given to their patients. Methods: Dental records of the Dental Department at the Jordan University Hospital were reviewed during the period from April 3rd until April 26th 2007 along with the issued prescriptions during that period. Results: A total of 1000 records were reviewed with a total of 53 prescriptions issued during that period. Thirty records documented the prescription by stating the category of the prescribed drug. Only 13 records stated the generic or the trade names of the prescribed drugs. Of these, 5 records contained the full elements of a prescription. As for local anesthetic injections, the term “LA used” was found in 22 records while the names and quantities of the local anesthetics used were documented in only 13 records. Only 5 records documented the full elements of a local anesthetic injection. Conclusion: The essential data of drug prescriptions and local anesthetic injections were poorly documented by the investigated group of dental specialists. It is recommended that the administration of the hospital and the dental department implement clear and firm guidelines for dental practitioners in particular to do the required documentation procedure.

BackgroundChronic granulomatous disease is an extremely rare primary immunodeficiency syndrome that can be associated with various oral complications. This can affect high number of patients. However, data on oral complications is sparse. Here we will review the literature and describe the orofacial findings in 12 patients.FindingsThe age range was 5-31 years. Oral findings were variable, and reflected a low level of oral hygiene. They included periodontitis, rampant caries, gingivitis, aphthous-like ulcers, and geographic tongue. One patient had white patches on the buccal mucosa similar to lichen planus. Another patient had a nodular dorsum of the tongue associated with fissured and geographic tongue. Biopsies from the latter two lesions revealed chronic non-specific mucositis. Panoramic radiographs showed extensive periodontitis in one patient and periapical lesions in another patient.ConclusionPatients with chronic granulomatous disease may develop oral lesions reflecting susceptibility to infections and inflammation. It is also possible that social and genetic factors may influence the development of this complication. Therefore, oral hygiene must be kept at an optimum level to prevent infections that can be difficult to manage.

Objective: The aim of this study was to determine the therapeutic adult antibiotics prescribed by dental practitioners working in the Jordan University Hospital. Methods: Adult dental prescriptions for therapeutic antibiotics issued between 1 January 2003 and 31 May 2004 by dental specialists working in the Jordan University Hospital were included in this study. Data included the name of the antibiotic as well as the dose, quantity and presentation of the drug. Descriptive statistical analysis was carried out. Results: Amoxycillin and metronidazole were the most commonly prescribed antibiotics, with 60% of the prescriptions containing amoxycillin and 39.4% containing metronidazole. 20.4% of the prescriptions were combination prescriptions containing metronidazole. In this study, long courses were observed for amoxycillin (60.5%), cephalosporins (21%) and metronidazole (59.7%). Conclusions: It seems that in the sample studied, Jordanian dental specialists have a tendency towards overprescribing antibiotics both in quantity and duration. This may constitute a problem particularly when considering the remaining sectors of less well-educated dental practitioners. The results will be used to increase awareness among dental practitioners in the field of antibiotic prescribing throughout the University of Jordan and the Jordanian Dental Association.

Esthetic Considerations for Reconstructing Implant Emergence Profile Using Titanium and Zirconia Custom Implant Abutments: Fifty Case Series Report

Ahmad Kutkut; Osama Abu-Hammad; Richard Mitchell

Titanium and zirconia custom implant abutments are now commonly used for esthetic implant dentistry. Custom implant abutments allow the clinician to improve an implants emergence profile, to customize cervical margins in accordance with the anatomy of the natural root, and to compensate for poor implant angulation. All of these are essential for optimum esthetic outcomes. Computer-aided design/computer-aided machining (CAD/CAM) technology allows the clinician to design custom implant abutment configurations and create natural-looking superstructures that are in harmony with the adjacent dentition and soft tissue. The CAD/CAM technique provides precise fit, reduces the cost of the procedure, and eliminates dimensional inaccuracies inherent in the conventional waxing and casting technique. The aim of this report is to describe a simplified technique for reconstructing emergence profiles during implant restoration using milled titanium and zirconia custom implant abutments. The results of 50 consecutive cases are reported.

Aims: We estimated the number of users of tobacco, particularly narghile(water pipe) among a sample of women working at a higher education institute in Jordan. We also investigated the attitudes of narghilesmokers to their habit, together with their willingness to stop NS; and finally their awareness to oral health and their perceptions about the harmful effects of NS. Study Design: The study was a cross-sectional survey whereby the sample was conveniently selected from all the faculties, institutes and centres of the University. Place and Duration of Study:University of Jordan, Amman, Jordan during July 2011. Methodology: Data were collected by allowing the participants to complete a pre prepared questionnaire privately. Statistical analysis was performed using theSPSS program. Results:Among the (96) participants, 24 ladies (25%) were smokers mostly (79.2%) of narghile. Demographic and social data of age, marital status, education level and number of children did not seem to affect smoking status. Friends and relatives were the

to minimise long term morbidity for the patient. Complications include trismus, pain, infection, and damage to the inferior alveolar and lingual nerves.1 To prevent needle breakage practitioners should use 27-gauge 35 mm needles for IAN block, avoid inserting to full length or burying the needle in the tissues, ensure patient cooperation thus avoiding sudden movements, and avoid bending needles or changing direction while still located deep in the tissues or exerting lateral pressure on withdrawal.3 A.
