OBJECTIVE The study evaluated the clinical performance and marginal adaptation of  direct and semi-direct class II composite restorations  in a split-mouth design over 3.5 years . DESIGN 44 upper posterior teeth in 11 adults with primary carious lesions were treated with 22  direct and 22  semi-direct restorations . Conventional cavities were prepared for both types of restorations . A fine fine hybrid composite ( APH ) and a multifunctional adhesive system ( Prisma universal bond 3 ) were used for all restorations . The incremental " 3-sited light curing " technique was applied to direct restorations . Semi-direct inlays were prefabricated on silicone casts and post-cured using light and heat .  Clinical performance was evaluated using modified USPHS parameters , while marginal adaptation was judged on replicas , using SEM and a st and ardized evaluation technique . RESULTS Clinical results after 3.5 years revealed a 100 % retention rate with no fractures , sensitivity or recurrent caries for both types of restorations . SEM-evaluation of the occlusal margins showed at the tooth-restoration interface relatively low rates of marginal openings over the observation period ( 4 - 8 % ) . Marginal restoration fractures ranged between 1 and 2 % , marginal tooth fractures between 3 and 9 % . Differences between the restorative techniques and after the different time observation periods were not statistically significant . Proportions of marginal fractures and openings at the restoration-luting composite interface were less than 10 % after 3.5 years . CONCLUSION The results indicated no significant differences for direct and semi-direct fine hybrid composite restorations  in medium size cavities in posterior teeth with respect to clinical performance and marginal adaptation over 3.5 years The objective of this r and omized control trial was to compare the five-year clinical performance of direct and indirect resin composite restorations replacing cusps . In 157 patients , 176 restorations were made to restore maxillary premolars with Class II cavities and one missing cusp . Ninety-two direct and 84 indirect resin composite restorations  were placed by two operators , following a strict protocol . Treatment technique and operator were assigned r and omly . Follow-up period was at least 4.5 yrs . Survival rates were determined with time to reparable failure and complete failure as endpoints . Kaplan-Meier five-year survival rates were 86.6 % ( SE 0.27 % ) for reparable failure and 87.2 % ( SE 0.27 % ) for complete failure . Differences between survival rates of direct and indirect restorations [ 89.9 % ( SE 0.34 % ) vs. 83.2 % ( SE 0.42 % ) for reparable failure and 91.2 % ( SE 0.32 % ) vs. 83.2 % ( SE 0.42 % ) for complete failure ] were not statistically significant ( p = .23 for reparable failure ; p = .15 for complete failure ) . Mode of failure was predominantly adhesive . The results suggest that direct and indirect techniques provide comparable results over the long term ( trial registration number : IS RCT N29200848 ) STATEMENT OF THE PROBLEM Objective long-term clinical data are necessary to assess the performance of modern posterior composites as direct and indirect restorations . PURPOSE This prospect i ve , long-term clinical trial evaluated direct and indirect composite restorations for clinical acceptability as posterior restoratives in single or multisurface cavities and provided a survey on the 3-year results . MATERIAL AND METHODS Under the supervision of an experienced dentist , 9 dental students placed 88 composite restorations ( Tetric , blend-a-lux , Pertac-Hybrid Unifil ) , 43 direct composite restorations , and 45 indirect inlays .  Clinical evaluation was performed at baseline and in yearly intervals after placement by 2 other experienced dentists , using modified USPHS criteria . A third follow-up of 60 restorations took place within 33 to 36 months after placement . RESULTS A total of 93 % of indirect and 87 % of direct restorations were assessed to be clinical ly excellent or acceptable . During the third year , 1 direct restoration in a molar failed because of margin opening . Indirect inlays exhibited a significantly better anatomic form of the surface than direct composite restorations . Premolars revealed a significantly better marginal integrity and anatomic form of the surface than molars . Restorations in molars exhibited a significantly higher failure rate compared with premolars . CONCLUSION Posterior composite restorations provided a satisfactory clinical performance over a 3-year period , even if placed by relatively inexperienced but supervised students AIM The aim of this study was to assess the clinical performance of two adhesive restorative systems ( Single Bond/Filtek P-60 and Single Bond/Filtek Z-250 ) in posterior teeth using a modified United States Public Health Service ( USPHS ) system . METHODS AND MATERIAL S A total of 70 restorations were placed in molars and premolars in 30 patients ( 14 females and 16 males ; 18 - 40 years ) by one operator . All restorations were directly evaluated by two examiners at baseline , six months , and 12 months using the following modified USPHS rating criteria : marginal integrity , marginal discoloration , surface texture , contour , postoperative sensitivity , and recurrent caries . RESULTS At six and 12 months all restorations were available for evaluation of marginal discoloration , surface texture , contour , postoperative sensitivity , and recurrent caries that remained with 100 % Alpha-ratings at recalls for both restorative systems . Marginal integrity for P-60 was scored as 94.3 % and 91.4 % Alpha at six and 12 months , respectively , and rates for Z-250 were 100 % and 97.1 % Alpha at six and 12 months , respectively . Statistical analysis was completed with Fisher 's exact and McNemar Chi-square tests at a significance level of 5 % ( P<0.05 ) . CONCLUSION All restorations were clinical ly satisfactory and no significant differences were found among them . CLINICAL SIGNIFICANCE Posterior resin composite restorations placed under appropriate conditions provide a satisfactory clinical performance STATEMENT OF PROBLEM Few long-term clinical studies have reported data of modern posterior composites as direct and indirect restorations . PURPOSE This prospect i ve , long-term clinical trial ( 1 ) evaluated direct and indirect composite restorations for clinical acceptability as posterior restoratives in single or multisurface carious teeth and ( 2 ) provided a survey on the 2-year results . MATERIAL AND METHODS Nine dental students placed 88 composite restorations ( Tetric , blend-a-lux , Pertac-Hybrid Unifil ) , 43 direct composite restorations and 45 indirect inlays , under the supervision of an experienced dentist . The first clinical evaluation was performed 11 to 13 months after placement by 2 other experienced dentists , using modified USPHS criteria . A second follow-up of 60 restorations took place within 20 to 26 months after placement . RESULTS A total of 93 % of indirect and 90 % of direct composite restorations were assessed to be clinical ly excellent or acceptable . Two restorations ( 1 indirect composite inlay and 1 margin of a direct composite restoration )  failed during the second year because of fracture . Indirect inlays demonstrated a significantly better " anatomic form of the surface " than direct composite restorations . Premolars revealed a significantly better margin integrity and postoperative symptoms than molars . CONCLUSION Posterior composite restorations provided a satisfactory clinical performance over a 2-year period when placed by relatively inexperienced but supervised students OBJECTIVES The Atraumatic Restorative Treatment ( ART ) approach was compared with the traditional amalgam ( TA ) approach in order to test their appropriateness to complement a preventive and educational school oral health programme in Syria . METHODS Using a parallel group design , 370 and 311 grade 2 children were r and omly assigned to the ART and the TA group respectively . Eight dentists placed 1117  single- and multiple-surface restorations .  A modified actuarial method was used to estimate survival curves . The jackknife method was applied to calculate the st and ard error in the cumulative survival percentages . RESULTS A statistically significant difference in cumulative survival percentages between single-surface non-occlusal ART and comparable amalgam restorations was observed after 4.3 , 5.3 and 6.3 years . The survival of single-surface non-occlusal  ART  posterior restorations ( 80.2 + /- 4.9 % ) was statistically significantly higher than that of occlusal posterior ART restorations ( 64.8 + /- 3.9 % ) at evaluation year 6.3 . There was no statistically significant difference observed between survival percentages of large ( 55.8 + /- 10 % ) and that of small ( 69.2 + /- 4.6 % ) single-surface posterior ART restorations after 6.3 years . There was an operator effect observed for single-surface ART and comparable amalgam restorations . Secondary caries was observed in 2.3 % of single-surface ART restorations and in 3.7 % of single-surface amalgam restorations during the 6.3 year observation period . CONCLUSIONS The ART approach provided higher survival percentages for single-surface restorations than the TA approach over 6.3 years and is therefore appropriate for use in school oral health programmes . Secondary caries was only a minor reason for ART restorations to fail . An operator effect was observed for both treatment approaches AIM To evaluate the effectiveness of three different types of  glass ionomer restorations placed in children 's teeth using the ART technique two years after placement by either dentists or primary health care workers . SETTING The rural district of Palpa in western Nepal . METHOD An opportunistic non-r and omised field study , commenced in April 1997 . Three different glass ionomer restorative cements were used : Fuji IX ( GC ) , Dentsply Baseline ( DENTSPLY/DeTrey ) , and S.S. WhiteR ( S.S. White ) . The restorations were assessed two years later by an independent evaluator , who was blind to the type of restorations used and also blind to the operators . RESULTS Four primary health care workers and two dentists restored 163 primary and permanent teeth using h and instruments . One and two surface restorations were placed in 105 students ranging from 3 to 19 years of age from seven schools . After two years , 79 ( 75 % ) of the restorations survived and 27 ( 25 % ) failed , while 100 % of 21 evaluated single surface restorations placed on permanent molars with Fuji IX survived . There was no statistically significant difference in the survival of the restorations placed by dentists and placed by primary health care workers , which corroborates that both groups are both capable of performing the technique satisfactorily . CONCLUSIONS ART is very effective for one surface permanent molars using improved glass ionomer cements design ed for the ART technique PURPOSE The aim of this long-term follow-up study was to collect up to 17 years of survival data of endodontically treated single teeth with or without a prefabricated metal post .  MATERIAL S AND METHODS Single teeth were provided with direct composite resin core-crown reconstructions with or without posts by 15 operators . Restorations consisted of either a prefabricated metal post and a composite core-crown reconstruction or a post-free direct composite reconstruction . Allocation of either restoration was performed by balanced drawing . These restorations were not covered by an artificial crown . The study sample consisted of 87 patients who received 98 core-crown reconstructions .  The performance of the restorations was evaluated based on data collected from the files of the clinicians currently monitoring the oral health of the patients . The survival probability was analyzed at different levels : on the restoration level and on the level of the tooth carrying the restoration . Kaplan-Meier analysis was used to compare survival probabilities . RESULTS Post placement showed no influence on the survival probability at either level ( P > .05 ) . The estimated overall survival rate at 17 years was 53 % + /- 14 % at the restoration level and 79 % + /- 11 % at the tooth level . CONCLUSION The results of this long-term follow-up study showed no difference in survival probabilities between different direct composite resin core-crown reconstructions of endodontically treated single teeth ( with or without a post ) PURPOSE To retrospectively evaluate the 6-year survival rates and technical/ biologic complication rates of single-retainer glass-ceramic resin-bonded fixed dental prostheses ( RBFDPs ) .  MATERIAL S AND METHODS Forty patients with 49 anterior/posterior glass-ceramic RBFDPs were included . The RBFDPs  replaced 11 maxillary/m and ibular central incisors , 18 lateral incisors , 18 premolars , and 2 molars . Patients willing to participate were clinical ly and radiologically examined . The technical outcome was assessed with modified United States Public Health Service criteria . Fracture and /or chipping of the restoration , occlusal wear , marginal adaptation , marginal discoloration , shape , surface texture , and esthetic integration were recorded . Tooth vitality and postoperative sensitivity were tested . The following biologic parameters were assessed at test and control teeth : probing pocket depth , gingival recession , attachment loss , bleeding on probing , furcation involvement , and periodontal mobility . Statistical analysis was performed with exact 95 % confidence intervals to relative frequencies and the paired t test . RESULTS Twenty-eight patients with 35 RBFDPs participated . The mean follow-up of the RBFDPs was 6 years . Twelve patients with 14 RBFDPs were not willing to participate or not available . No catastrophic failures occurred . The 6-year survival rate of the examined RBFDPs was 100 % . No debonding was recorded . Chipping of the ceramic was found in 5.7 % of the RBFDPs . Biologic outcomes were similar at test and control teeth . CONCLUSION Glass-ceramic RBFDPs exhibited promising clinical outcomes in both anterior and posterior regions Since single-tooth implant restorations were introduced 12 years ago ( Jemt 1986 ) , there has been continuous development both in the technical design and the aesthetic outcome of the treatment . In order to ensure high quality in single-tooth implant treatments a clinical follow-up study was carried out on patients treated with modifications to the original regimen . In this study 69 consecutive patients were provided with 80 single-tooth implant restorations .  The patients were followed for 3 years . There was continuous development of the prosthetic design during the time of the study , allowing us to analyse possible prognostic differences for the different prosthetic treatments . This study confirms earlier reports which describe the single-tooth implant treatment as a safe method with few surgical complications and minimal marginal bone loss . Only 1 implant was lost during the follow-up period and the average marginal bone loss was 0.48 mm over the 3-year follow-up period . Crowns veneered with acrylic and with gold casted directly to the abutments , screwed onto the implants , led to recurring prosthetic complications and gave an appearance of rapid ageing . The first generation of crowns made following the Cera-One design , sometimes produced a gap between the crown and the abutment associated with significant marginal bone loss during the first year . Few surgical or prosthetic complications were noted with cemented all-ceramic constructions , although the number of these crowns in this study was limited AIM This was to evaluate the influence of two methods of tooth-isolation on the survival rate of proximal ART restorations in the primary molars . METHODS The study was conducted in two rural divisions in Kenya , with 7 operators r and omly paired to a group of 8 assistants . A total of 804 children each had one proximal cavity in a primary molar restored using the ART approach .  During restorations 2 isolation methods , rubber dam or cotton wool rolls , and 3 br and s of glass ionomer cements were used by the operators . The restorations were then followed for a period of 2 years . STATISTICS SPSS 14.0 was used to analyse and relate the data obtained to the method of isolation used . RESULTS After 2 years 30.8 % of the ART restorations had survived . Higher survival rates of the restorations were obtained when using rubber dam irrespective of the GIC material or the operator . CONCLUSION Generally the survival rate of the proximal restorations in the present study was very low , but the use of rubber dam result ed in a higher survival rate of the restorations PURPOSE This study aim ed to assess the efficacy and short-term effectiveness of the morphology and function of direct and indirect cusp-replacing resin composite restorations . MATERIAL S AND METHODS In 94 patients , 106 cusp-replacing restorations for maxillary premolars were fabricated to restore Class II caries lesions with 1 cusp missing . Fifty-four direct ( Clearfil AP-X ) and 52 indirect ( Estenia ) resin composite restorations were placed following a strict protocol . The treatment technique and operator were assigned r and omly . Treatment time was recorded for all restorations . One-month postoperative evaluation included assessment of postoperative sensitivity and presence of occlusal and proximal contacts . RESULTS Treatment time for the indirect technique ( 68 + /- 17 min ) was longer than for the direct technique ( 45 + /- 13 min ) . Regression analysis revealed that the restorative method , operator , and location of the preparation outline had a statistically significant effect on the total treatment time . Occlusal contacts were observed in 94 % of the direct restorations and in 98 % of the indirect restorations ( chi-square , P>.05 ) . Mesial proximal contacts were present in 98 % of the direct and in 97 % of the indirect restorations ( chi-square , P > .05 ) . Distal contacts were present in 100 % of the restorations for both techniques . Postoperative sensitivity within 1 week posttreatment was reported for 11 % of the direct restorations and for 13 % of the indirect restorations , but decreased to 4 % and 6 % , respectively , after 1 month ( chi-square , P > .05 ) . CONCLUSION The results of this study suggest that in the short term , both direct and indirect adhesive techniques are adequate to restore the morphology and function of premolars presenting with Class II caries lesions and a missing cusp AIM : The objective of the study was to determine the influence of the experience of the operator and the assistant on the survival rate of proximal ART-restorations after 2 years when placed using two methods of tooth-isolation and three glass ionomer cement-br and s. STUDY DESIGN : A clinical intervention study . METHODS : Each of 804 children aged 6–8 years received one proximal restoration in their primary molars . The restorations were placed by ‘ experienced/inexperienced ’ operators r and omly paired with ‘ experienced/ inexperienced ’ assistants . The atraumatic restorative treatment ( ART ) approach was used with 3 br and s of glass ionomer cements ( GIC ) and 2 tooth-isolation methods ( rubber dam vs cotton rolls ) . Trained and calibrated evaluators evaluated the restorations , soon after placement and after 2 years . STSTISTICS : The data collected were analyzed using SPSS 14.0 , to determine and relate the survival rate of the restorations to the operator and assistant with respect to the other factors such as the restorative material used and the isolation method applied . RESULTS : After 2 years , the survival rate of the restorations was 30.8 % . In general , there were no statistical significant differences in the survival rate of the restorations made by the ‘ experienced ’ vs ‘ inexperienced ’ operators , but individually , the operator with more experience was associated with a significantly higher survival rate of the restorations . The experienced assistants were associated with significantly higher survival rates of the restorations . The most ‘ experienced ’ operator paired with any ‘ experienced ’ assistant and using rubber dam tooth-isolation method , was associated with a significantly higher survival rate of the restorations . CONCLUSION : The combination of the ‘ experienced ’ operator and assistant using rubber dam tooth-isolation method had the best chance of survival for proximal ART restorations , irrespective of the material -br and used OBJECTIVES This prospect i ve clinical study evaluated the performance of indirect , anterior , surface-retained , fibre-reinforced-composite restorations ( ISFRCR ) . METHODS Between June-2003 and January-2011 , a total of 134 patients ( 83 females , 51 males , 16 - 68 years old ) received 175 ISFRCRs ( local ethical registration number : 14/9/4 ) . All restorations were made indirectly on a plaster model using unidirectional E-glass fibres ( everStick C&B , StickTech ) in combination with a laboratory resin composite ( Dialogue , Schütz Dental ) and cemented according to the instructions of 4 resin cements [ ( RelyX ARC , 3M-ESPE , n=61 ) , Bifix DC , VOCO , n=45 ) , Variolink II ( Ivoclar Vivadent , n=32 ) and Multilink ( Ivoclar Vivadent , n=37 ) ] . After baseline recordings , patients were followed at 6 months and thereafter annually up to 7.5 years . The evaluation protocol involved technical ( chipping , debonding or fracture of tooth/restoration ) and biological failures ( caries ) . RESULTS Mean observation period was 58 months . Altogether , 13 failures were observed [ survival rate : 97.7 % ] ( Kaplan-Meier ) . One catastrophic fracture [ ( cement : RelyX ARC ) , eight partial debonding ( cement : Bifix DC ( 5 ) , Multilink ( 1 ) , RelyX ARC ( 1 ) , Variolink II ( 1 ) ] and four delaminations of veneering composite [ ( cement : Bifix DC ( 2 ) , RelyX ARC ( 1 ) , Multilink ( 1 ) ] were observed . Except one replacement , all defective restorations were repaired or recemented . Annual failure rate of ISFRCRs was 1.73 % . The survival rates with the four resin cements did not show significant differences ( RelyX ARC : 98.3 % ; Bifix DC : 93.5 % ; Variolink 2 : 100 % ; Multilink : 100 % ) ( p=0.114 ) . Secondary caries did not occur in any of the teeth . CONCLUSION The 3-unit anterior indirect surface-retained resin-bonded FRC FDPs showed similar clinical survival rate when cemented with the resin cements tested . Experienced failures in general were due to debonding of the restoration or delamination of the veneering composite . CLINICAL SIGNIFICANCE 3-unit surface retained resin-bonded FRC FDPs could be considered minimal invasive and cost-effective alternatives to conventional tooth- or implant-borne FDPs .  Failures were mainly repairable in the form of chipping or debonding depending on the resin cement type This study compared microleakage between  indirect composite inlays and direct composite restorations . Forty-eight st and ard inlay MOD cavities , with cervical margins located either in enamel or dentin , were prepared in extracted human third molars . The specimens were r and omly divided into 3 groups ( n=16 ) . In the control group , the cavities were restored with the composite Filtek Z250 ( 3 M ESPE ) . For the experimental groups , indirect restorations were made with the Artglass ( Heraeus-Kulzer ) or Belleglass HP ( Kerr Laboratories ) systems and cemented with the dual curing cement RelyX ARC ( 3 M ESPE ) . The adhesive system Single Bond ( 3 M ESPE ) was applied on all groups . The specimens were su bmi tted to thermolcycling , coated with nail varnish , then immersed in 2 % basic fuchsine aqueous solution for 24 hours . The teeth were then sectioned and leakage scores were evaluated ( 40x ) , based on a st and ard ranking . Data were su bmi tted to statistical analysis ( Mann-Whitney and Kruskal-Wallis tests ) with a 95 % confidence level . No statistical difference was found between substrates ( p=0.595 ) , and the material s performed similarly in dentin ( p=0.482 ) . Direct restorations showed higher leakage than indirect restorations at the enamel margins ( p=0.004 ) . Within the limitations of this experimental design , overall leakage was similar between both substrates , while the indirect systems provided a better sealing than direct composites only in enamel PURPOSE To report the 4-year clinical performance of  posterior resin-based composite restorations placed using the total-etch technique . MATERIAL S AND METHODS Over a period of 1 year , 726 restorations ( 248 molars , 478 premolars ; 260 Class I , 466 Class II ; 540 replacements , 186 primary decay ) were placed on conservative preparations , using the incremental placement technique in a clinical environment . Baseline data were collected , and the restorations were evaluated after 4 years . Z100 and Scotchbond Multi- Purpose ( SBMP ) ( 3 M Dental Products , St. Paul , Minnesota ) were used as the restorative system . The criteria evaluated were color match , marginal adaptation , anatomic form , cavosurface marginal discoloration , axial contour , interproximal contact , secondary caries , postoperative sensitivity , and tooth vitality . RESULTS At baseline , 24 % of the teeth restored presented postoperative sensitivity ; 86 % of the sensitive teeth were from the replacement group . At 4 years , all teeth were vital to cold test . Eighteen restorations ( 2.5 % ) presented clinical ly detectable marginal fracture . The shade was acceptable in all restorations . Cavosurface marginal discoloration was observed in 47 restorations ( 6.5 % bravo scores ) . Axial contour , interproximal contact , and marginal adaptation received 100 % alfa scores . No secondary caries was diagnosed in any of the teeth examined . None of the examined restorations required replacement . CLINICAL SIGNIFICANCE Under controlled clinical conditions , posterior resin-based composite restorations placed with the total-etch technique and restorative Z100/SBMP have the potential to present a high success rate at 4 years . None of the examined restorations required replacement , and there was no clinical ly detectable wear in any of the restorations . Simultaneous etching of enamel and dentin followed by the application of a resin adhesive can be considered an adequate modality of pulp protection in nonexposed tooth preparations PURPOSE The aim of this prospect i ve case series study was to assess the clinical performance of single restorations in the posterior m and ible supported by 6-mm implants . MATERIAL S AND METHODS Twenty-one consecutive patients with one or more missing premolars or molars in the posterior m and ible and with an estimated bone height of 8 mm between the top of the ridge and alveolar nerve were included . Each patient was to receive one or more 6-mm implants ( OsseoSpeed 4.0 S , Astra Tech Implant System , Dentsply Implants , Mölndal , Sweden ) without any grafting . After a 3-month osseointegration period , the implants were restored with custom-made titanium abutments ( Atlantis abutment , Dentsply Implants ) and cemented zirconia-based porcelain crowns .  Clinical and radiographic examinations were performed at placement of the restoration and 12 months thereafter . Next to this , patients ' satisfaction was scored before treatment and after 12 months with the restoration in function . RESULTS Implant survival was 100 % . From loading to the 12-month follow-up , mean marginal bone loss was 0.14 mm ( SD : 0.4 ) . Mean scores for plaque , calculus , gingiva , bleeding , and pocket probing depth were low . Patients ' satisfaction was high . CONCLUSION One-year follow-up data revealed that 6-mm dental implants inserted in the resorbed posterior m and ible provide a solid basis for single tooth restoration
An association between the kind of complications and different types of restorations could not be established .
Nevertheless , a relatively high failure rate due to caries and ceramic fractures was noted
OBJECTIVE The aim of this study was to identify if different types of indirect restorations used for single teeth had different biological and technical complications , as well as survival rates .
