ABSTRACT
Background: All-in one adhesive systems reduce the number of steps and thus possible soures of error that may occur in clinical wage of adhesives; it is hoped that they also have good clinical performance. Objective: To evaluate the clinical performance of a selfetch adhesive system - Adper's Prompt L-Pop in noncarious cervical lesions over a six months period. Method: One hundred and eighty-one (181) restorations were placed by one operator for 35 patients. The self-etch adhesive was applied to the cavity and composite was used to restore the teeth. The restorations were evaluated at baseline; 3 months and 6 months according to the modified Ryge's criteria. Restorations were monitored for postoperative sensitivity; retention rates and marginal adaptation. Results: At six months; 160 restorations were available for evaluation in 32 patients. The retention rate was 96.3; postoperative sensitivity was scored Alpha for all restorations (no sensitivity); and 3.7restorations had marginal adaptation failure at six months. Conclusion: The adhesive system tested exhibited very good clinical performance at the end of six months

Introduction : Le but de la présente étude est d'évaluer le taux de succès et les facteurs affectant le pronostic de l'auto-transplantation immédiate de la troisième molaire mandibulaire, au site de la première ou la deuxième molaire homolatérale après un suivi clinique et radiologique sur une période de trois ans. Matériel et méthodes : Un total de 90 troisièmes molaires mandibulaires ont été immédiatement transplantées pour remplacer la première ou la deuxième molaire homolatérale jugées non restaurables. Le stade de développement des molaires auto-transplantées varie de 3 à 7 selon la classification de Moorrees. Pour les molaires matures, le traitement canalaire est réalisé 1 à 2 semaines plus tard. A l'issue des contrôles cliniques et radiographiques des troisièmes molaires transplantées échelonnés selon un calendrier prédéfini, des statistiques descriptives ainsi que l'analyse du taux de réussite et des facteurs affectant le pronostic ont été réalisées. Résultats : L'âge moyen des patients était de 22,80 ans. Le taux de succès est de 87,8%. Le taux de réussite de l'auto-transplantation des troisièmes molaires immatures et matures est respectivement de 91,2% et de 81,8%. Le taux d'échec est de 12,2%.Le temps extra-alvéolaire apparait comme la cause principale des complications. Parmi les 11 transplantations considérées comme un échec, la résorption radiculaire externe est la manifestation principale représentée par 8 cas, suivi de 2cas d'ankylose et d'un cas d'expulsion du transplant. Conclusion : L'auto-transplantation immédiate des troisièmes molaires mandibulaires au site de la première ou de la deuxième molaire homolatérale est une solution viable et une alternative à la réhabilitation prothétique conventionnelle ou au traitement implantaire d'un point de vue thérapeutique et économique.
Introduction: The aim of the present study was to evaluate the success rate and to the factors affecting the prognosis of the immediate auto-transplantation of the mandibular third molar, in homolateral first or second molar site after clinical and radiological follow-up over a period of three years. Material and methods: A total of 90 mandibular third molars were immediately autotransplanted to replace homolateral lost first or second molar. The development stage of autotransplanted molars varied from 3 to 7 according to Moorrees. Root canal treatment began for mature molars 1 to 2 weeks later. Clinical and radiographic checkup of the transplanted third molars were done according to predesigned record form. Descriptive statistics and statistical analysis about success rate and to the factors affecting the prognosis were performed. Results: The mean age of treated patients was 22.80 years. The success rate was 87.8%. The success rates of the auto-transplantation of third immature and mature molars were 91.2% and 81.8%, respectively. The failure rate is 12.2% and extra-alveolar time appears as the main cause of complications. In all, 11 transplants were considered a failure. External radicular resorption appeared to be the principal manifestation with 8 cases, followed by 2 cases of ankylosis and 1 of transplant expulsion. Conclusion: Immediate auto-transplantation of the mandibular third molar teeth in homolateral first or second molar site is an interesting treatment alternative to conventional prosthetic rehabilitation or implant treatment in cases of lost molars from both a therapeutic and an economic point of view.

Reported are the results of an evaluation of process indicators and outputs for the Expanded Programme on Immunization (EPI) in Mozambique which were used to modify immunization strategies from 1985 to 1987. In 1986 according to cluster sample surveys, 84% of children in Maputo, the capital, were fully vaccinated. In other cities in the country, vaccination coverage increased from an average of 36% in 1985 to 55% in 1987. The major determinants of low vaccination coverage were provision of vaccination services at health centres on less than 3 days per week; missed opportunities; and vaccinating too early or with too short an interval between doses. The results of sentinel site surveillance in Maputo indicated that EPI had a marked impact on neonatal tetanus and to a lesser extent on poliomyelitis and measles. Evaluation led to changes in EPI policy in Mozambique (e.g., adoption of a uniform national vaccination schedule and discontinuation of the use of expired vaccine) and strategies (elaboration of different strategies for urban areas, rural areas, and displaced people). Also, performance was improved by involving programme managers and implementors in evaluation, and by providing timely and widespread feedback of results to policy-makers, peripheral health workers, and the community
