Interim endodontic therapy for alveolar socket bone regeneration of infected hopeless teeth prior to implant therapy.

The immediate placement of implants in the fresh extraction sockets of infected teeth with periradicular and periapical lesions is contraindicated because of both the infection and the loss of architecture required for proper implant placement. There are 4 approaches for implant replacement of a hopeless tooth with lesions: (1) extraction and delayed implant placement; (2) extraction, debridement, guided bone regeneration (GBR), guided tissue regeneration (GTR), and delayed implant placement; (3) extraction, intrasocket debridement, and immediate implant placement; or (4) extraction, debridement, GBR, GTR, and simultaneous implant placement. The extraction of such hopeless teeth often results in large bone and soft tissue defects that are difficult to repair. This article introduces an alternative approach: interim endodontic implant site preparation, defined as a transitional, surgical, or nonsurgical endodontic treatment to regenerate the hopeless tooth bone defects and prepare the site for proper implant placement. This article describes 3 distinct interim endodontic protocols used to manage 5 patients, all of whom had severely infected hopeless teeth with large lesions and were treatment planned for implant replacement: the first, interim nonsurgical endodontic treatment to restore the normal anatomy of the infected hopeless tooth; the second, interim surgical endodontics on the hopeless tooth with preexisting endodontic treatment to regenerate apical bone for primary implant stability, thus avoiding the involvement of the maxillary sinus and other critical anatomic structures; and the third, interim surgical endodontics on the hopeless tooth with preexisting endodontic treatment to confine the size of the osseous defect and simplify the GBR and GTR procedures. The outcome of interim endodontic treatment on these 5 patients demonstrated that tooth extraction would have been a less predictable approach. The interim treatment changed the overall direction of the patients' dental care. When treated, these hopeless teeth served many preventive, biologic, and esthetic functions. The infections of the alveolar sockets were eliminated, the alveolar bone defects were repaired through normal bone regeneration, and sockets anatomies were maintained or restored. Furthermore, the patients were spared maxillary sinus surgery and the possible complications resulting from major GBR and GTR procedures. In summary, the interim treatment facilitated tooth extraction and immediate implant placement.

Antibiotic prescription and dental practice within Saudi Arabia; the need to reinforce guidelines and implement specialty needs.

The aim of the present survey was to analyse the frequency and type of antibiotic prescriptions used in dental practice in Saudi Arabia, to assess the awareness of periodontal treatment need among dentists and specialists and to evaluate the distribution of dental specialties in Saudi Arabia. We distributed a questionnaire to 378 dentists including different specialists working in various major hospitals and dental departments. This same questionnaire was then redistributed, 3 years later, to 211 participants. Results from both surveys indicated that antibiotics were not always prescribed on a scientific basis. Cost was the most significant factor (p < 0.05). Interestingly, and although periodontal disease was included as one of the possible causes of infections, the penicillin group was shown to be the group of choice (p < 0.007) and was prescribed by 45% of all participants, metronidazole and tetracyclines followed and were the second most commonly prescribed antibiotics in both surveys (p < 0.05). It was further demonstrated that although the need for periodontics is present among patients and specialists, it is one of the least practised specialties (p < or = 0.008) along with oral surgery (p < or = 0.36).

2.3 Towards global convergence of education, training, quality, outcome and assessment.

The purpose of this section's report is to propose strategies which will help those committed to promoting and implementing higher standards in dental education. There is a wide variety of systems throughout the world. These systems are developed, governed, operated and applied differently. Their standards, whether they are controlled by governments (federal and/or state), councils, universities or professional organizations are frequently determined cooperatively with dental educators, so that there is often some agreement among interested constituencies as to the content and application of the standards. These standards, whether they be called 'accreditation standards"requirements' or 'guidelines' (formal or informal), or written as laws or statutes reflect a region's history, traditions, culture and socio-economic realities. The emphasis in this report will be on the development of an organic or growing electronic database containing worldwide information relating to standards in dental education. This database might contain or be linked with similar sources detailing, inter alia, best practices, innovations and core values as they relate to the convergence of standards in education, professional training, continuous quality analysis, assessment and outcome. The linking of such a database to others containing electronic curricular modules, clinical management and practice information needs to be further developed.
