University of the WesternCape, Cape Town.16Pro.thodontic reabilltatica with a set of complete denture usually requires six to sevenclinical sessians. This poses problums for a group of patients who, for one reason or asother,find it almost impossible to ass such frequent visits are thus denied oral health cars.Iowever, the number of pointsots ould be reduced to three if a modified oomplete denturetechnique is adopted. his technique consists of only thre clinical s"siont the first forexamination, diagnosis, treateet planning, preliminary and wortino impressions and maxillo-sandibular reords; the s*eo5d for try-in and protrusive record and the final session for theissue, Although the first clinical seesson is rather long, thi has enabled patientswho would have been denied colete denture service due to the impracticality of lking frquentvisits, the opportunity to avail themslves of this service.Dental cerise in developing countries is widesprad and affocts millions of people. Rsetorationof these carious teeth with conventional restoration is not necessarily the correct strategy dueto (1) a lack of huean and financial resources and (2) the high failure rate (520-6)0) associatedwith conventional restoration. The high failure rate has been linked songset other factors tothe presence of residual decay under the restoration and/or to the microleskage that occurs atthe tooth-restoration interphase. Pivotal to the appropriate restorative technique (ART)philosophy is the removal of all infected dentin. and the sealing of the lesion with a glessionser cement. This study evaluated ia..cir. microleakage arond Fuji IX restorations sealedwith a sealant. 30 Caries extracted teeth were restored by pro-clinical dental students usingFuji IX with a sealant. The restored teeth were thermo-cycled between sC snd 55sC for 500 cyclesand then placed in a basic fuchoin solution for 24 hours. u ts showed g atBased on these results this study recommreds tha utilization of:1. the micro-cavity preparation2. a caries-cavity to ensure optimal renoval of all infectad dentine3. a glasa-ionoser (Fuji IX) restoration sealed with a oealant.This philosophy will result in an appropriate resistant to microleakage and which will act as adeterrent to reurrent caries due to its continuing fluoride release.One and 2 Year Results of ART Procedures in Zimbabwe.

During the first year,ihmtil Superior was used as the filling/sealing material whilst Fuji IX was used in lo9e. oneand 2 yer results for on surface ART restorations using Cheelil showed a cumeulative survivalfigure of 93.40 and 59.2% respectively. Aftar 2 years, only one of the 54 restorations wasevalusted a failure because of the presence of caries. Glass ionomar sasbante had bean placedin active/inactive early enamel lesions. Caries was present in 0.00 and 3.80 of the surfecosesaled after 1 and 2 years, respectively.The 1 year survival figure for one-surface ART restorations using Puji 1X was 97.9 Caries wasabsent almogsid the restorations. After 1 year, 2.90 of the surface sealed with Fuji IX glaseionaor showed signs of caries. :t is oncluded that ART makes restorative dental care moreavailable to laxger groups in the population.Supported by Lever Brothers LTD zimbe; N00 CollaboratIng CentreCysts of the oral region are lesions that occur frequently.
