PURPOSE To evaluate the 24-month clinical performance of  cervical restorations  using a nanohybrid and a flowable resin composite with a one-step self-etching adhesive . MATERIAL S AND METHODS Twenty-one patients with at least one pair of non-carious cervical lesions participated in this study . A total of 134 non-carious cervical lesions were restored ( 67 with a nanohybrid resin composite , Gr and io ; 67 with a flowable resin composite , Gr and io Flow ) using a one-step self-etching adhesive system , Futura Bond NR , by one dentist . The restorations were evaluated for retention , color match , marginal discoloration , marginal adaptation , surface texture , anatomic form , and secondary caries by two calibrated examiners at baseline and after 6 , 12 , and 24 months using modified USPHS criteria . The survival rates of the restorations were calculated by the Kaplan-Meier estimator . The comparison of resin composites for each category was performed with the Pearson chi-square test , and the performance of restorations at baseline and after each recall time was evaluated using McNemar 's test ( p < 0.05 ) . RESULTS All patients attended the 24-month recall . The retention rates at 6 months were 66 % and 58 % , and 61 % and 57 % at 12 months for Gr and io and Gr and io Flow , respectively . At the 24-month recall , the retention rate was 60 % for Gr and io and 54 % for Gr and io Flow . No statistically significant differences were found in retention rates among the restorative material s in any evaluation period ( p > 0.05 ) . For marginal discoloration and anatomical form , three Gr and io and three Gr and io Flow restorations showed Bravo scores at the end of 24 months . The restorations in both groups had Alfa ratings of 100 % for the rest of the criteria evaluated . CONCLUSION The nanohybrid and flowable resin composites showed similar clinical performances in the restoration of non-carious cervical lesions over 24 months PURPOSE To determine the 18-month clinical performance of four tooth-colored restoratives in non-carious cervical lesions . MATERIAL S AND METHODS Buccal abrasion lesions in 83 teeth were restored with each of the following material s : Fuji Cap II , Fuji II LC , APH/Universal Bond 3 , Lite Fil II A/Imperva Bond . Baseline and an 18-month recall was carried out using the Ryge ( USPHS ) method for retention , color match , marginal adaptation , cavosurface marginal discoloration , anatomic form and secondary caries . RESULTS The USPHS results ( % alfa ) for the four products were , respectively : color match ( 9 % , 48 % , 57 % , 55 % ) , marginal discoloration ( 71 % , 76 % , 52 % , 50 % ) , marginal adaptation ( 24 % , 24 % , 33 % , 15 % ) , anatomic form ( 67 % , 86 % , 95 % , 45 % ) and retention ( 100 % , 95 % , 100 % , 65 % ) . Results indicated that ( 1 ) Fuji Cap II exhibited a poor color match at baseline ( 2 ) Color matching of Fuji II LC was comparable to the resin composites and ( 3 ) seven Lite Fil II/Imperva Bond restorations ( 35 % ) were dislodged after 1 1/2 years PURPOSE To clinical ly evaluate the 3-year performance of a one-bottle dentin adhesive in the restoration of non-carious cervical lesions ( NCCLs ) with resin composite . MATERIAL S AND METHODS 105 NCCLs were restored with either AElite Flow , Bisco Glaze ( both flowable resin-based composites ) or Silux ( a microfilled resin-based composite ) , using One-Step dentin adhesive . The cavities were cleaned with pumice and water slurry , the dentin lightly roughened with a fine diamond bur , and the restorations placed according to the manufacturer 's instructions . Patients were recalled at 6 months , 1 year , 2 years and 3 years , and restoration integrity and marginal discoloration assessed . RESULTS The overall retention rates were : 6 months , 100 % ; 1 year , 95 % ; 2 years , 87 % ; 3 years , 75 % . Marginal discoloration was negligible , and there was no significant difference among the material s , although there was a trend for it to be greater around the Bisco Glaze restorations The use of adhesive material s to restore non-carious cervical lesions ( NCCL ) has become the st and ard practice . Until recently , the most reliable material for restoring NCCL is glass ionomer cement , but the esthetics can be problematic . This study compared the retention of a self-etching adhesive , Clearfil SE Bond , with Clearfil ST resin composite ( SE ) , with the phosphoric acid-etch single bottle adhesive Single Bond with A110 resin composite ( SB ) and a resin-modified glass ionomer cement , Fuji II LC , ( FJ ) .  Ninety-two restorations in 20 patients ( mean age 61 years ) were placed . The teeth were restored r and omly and manufacturers ' instructions were followed . Patients were recalled at 6 months , 1 , 2 and 3 years and the restorations were evaluated for marginal staining . The restorations were photographed at baseline and at recall periods . At one year , 80 restorations were available for evaluation ; at 2 years , 65 restorations were evaluated and at 3 years , 55 restorations were evaluated . The cumulative retention rates at 1 year , 2 years and 3 years , respectively , were SE : 97 % , 93 % , 90 % ; SB : 86 % , 77 % , 77 % ; FJ : 100 % , 100 % , 97 % . At 3 years , RM-GIC performed the best , followed by Clearfil SE Bond/Clearfil ST . Single Bond/A110 's performance was significantly less than the other 2 material s ( p = 0.012 ) OBJECTIVE This controlled clinical trial evaluated the 5-year clinical performance of a self-etching primer system including selective enamel-etching with phosphoric acid and a one-bottle adhesive system . METHODS Seventy-two non-carious cervical lesions in 8 patients ( 4 male and 4 female ) with a mean age of 61.3 years ( range 45 - 78 ) participated in the study . An enamel bevel was placed and dentin lightly ground , and cavities restored with clearfil liner bond II ( LB ) or single bond ( SB ) in conjunction with a hybrid resin composite ( Clearfil AP-X ) . In the case of 27 cavities for LB , the enamel was pretreated with 37 % phosphoric acid for 10 s. Each patient received both types of restoration , which were distributed on a r and om basis . All restorations ( 37 restorations for LB and 35 restorations for SB ) were placed by one dentist . The restorations were evaluated blind after 5 years using modified USPHS criteria . The data were statistically analyzed using the Fisher 's exact test . RESULTS All but one restoration ( which was replaced by a crown after the 2-year recall ) were evaluated after 5 years . 100 % retention rates were recorded for both restorative groups . No caries was detected in association with any restorations . The only minor problem was marginal discoloration ; superficial and localized marginal discoloration occurred around 18 % of the restorations , and mainly at the dentin margin . There were no significant differences in the marginal integrity between the LB and SB groups . CONCLUSIONS Restorative material s used in this study demonstrated a good clinical effectiveness in the restoration of non-carious cervical lesions for 5 years OBJECTIVES Despite representing an important component of current dental adhesives , HEMA has been said to negatively influence the long-term stability of adhesion to dentine and enamel . The aim of this r and omised clinical trial was to evaluate the 3-year clinical performance of two one-step self-etch adhesives . METHODS Thirty patients had 175 non-carious cervical lesions restored with composite ( Gradia Direct Anterior , GC ) using either the HEMA-rich adhesive Clearfil Tri-S Bond ( C3S ; Kuraray ) or the HEMA-free adhesive G-Bond ( GB ; GC ) . The restorations were evaluated by two examiners at baseline , 6 , 12 , 24 and 36 months regarding retention , caries recurrence , marginal integrity and discoloration and post-operative sensitivity . The data were statistically analysed with GEE and McNemar tests ( p<0.05 ) . RESULTS The recall rate at 6 and 12 months was 100 % and decreased to 96.7 % at 24 and 36 months . At 3 years , the retention rate was 93.8 % for C3S and 98.8 % for GB ( p=0.14 ) . A pairwise comparison showed no significant differences between the two adhesives for all the parameters evaluated , irrespective of the recall ( p>0.05 ) . After 3 years , both adhesives presented an increase in the percentage of clinical ly acceptable marginal discoloration ( C3S : 32.9 % and GB : 26.8 % ) normally associated to clinical ly acceptable marginal defects ( C3S : 35.8 % and GB : 26.5 % ) . Only 1 dentine margin of a GB restoration presented a severe marginal defect ( 1.2 % ) and 1 C3S restoration presented caries recurrence . The overall 3-year clinical success rate was 92.6 % for C3S and 97.6 % for GB ( p=0.16 ) . CONCLUSION Both one-step self-etch adhesives presented an equally favourable clinical effectiveness at 3 years . CLINICAL SIGNIFICANCE HEMA is a monomer frequently present in dental adhesives in order to increase their wettability and hydrophilicity . However , this monomer negatively influences hydrolytic stability and durability of the adhesive interface complex . In this 3-year clinical trial no significant difference in bonding effectiveness was noticed between a HEMA-rich and HEMA-free one-step adhesive BACKGROUND The clinical performance of various tooth-coloured material s used to restore Non-Carious Cervical Lesions ( NCCLs ) has been evaluated . However , most of these evaluations were in western societies where soft diets requiring little mastication were common . The present study sets out to evaluate resin composite and RMGIC in the restoration of NCCLs among a Nigerian sub population group with fibrous diet requiring more rigorous mastication . PATIENTS & METHODS The study included all adult patients that presented at the Dental Hospital , Obafemi Awolowo University Teaching Hospitals Complex , Ile-Ife , Nigeria with non-carious cervical lesions over a period of six months . The teeth with non-carious cervical lesions in each patient were allocated into treatment with either resin composite or resin-modified glass ionomer cement by simple r and om sampling using ballots . The depth of the NCCLs was measured using a graduated flat ash periodontal probe . All the treatment was done by the first author according to the manufacturer 's instructions . Patients were recalled and evaluated at 48- hours , 3- months , 6- months and 12- months using the USPHS criteria . Data analysis was done using SPSS version 15 . The level of significance was put at 0.05 . RESULTS At the end of 12 months , 143 resin composite and 144 RMGIC restorations were evaluated , out of which 37 resin composite and 13 RMGIC restorations were dislodged , giving a retention rate of 74.1 % and 91.0 % respectively . The difference was statistically significant ( p<0.05 ) . For marginal discolouration , marginal adaptation , abrasion wear resistance , post operative sensitivity , and secondary caries , there were no statistically significant differences in the performance of resin composite and RMGIC . There was more retention failure of both resin composite and RMGIC restorations in NCCLs in m and ibular teeth than in maxillary teeth . The differences were statistically significant ( p<0.05 ) . CONCLUSION RMGIC demonstrated a higher retention rate in the restoration of non-carious cervical lesions than resin composite over a period of 12 month PURPOSE To study the clinical performance of two c and i date s for improvement of the original Gluma bonding system . MATERIAL S AND METHODS Eight teeth with cervical buccal abrasion/erosion lesions were identified in 40 patients . The lesions were conditioned with an oxalic acid solution followed by either a HEMA-glutaraldehyde bonding agent or a formamide-containing bonding agent . The lesions were restored with a hybrid composite . Each patient received the same number of restorations with the two different bonding formulations . All restorations were made by the same operator ( JK ) . Evaluations were based on the USPHS system . RESULTS No difference between the two groups as to retention , marginal adaptation and discoloration was observed after 3 years . Eight restorations were lost and a slight increase in marginal discoloration was seen during the observation period This controlled clinical trial evaluated the 2-year clinical performance of a one-bottle etch- and -rinse adhesive and resin composite system ( Excite/Tetric Ceram ) compared to a resin-modified glass ionomer cement ( RMGIC ) ( Vitremer/3 M ) in non-carious cervical lesions . Seventy cervical restorations ( 35 resin composite - RC- restorations and 35 RMGIC restorations ) were placed by a single operator in 30 patients under rubber dam isolation without mechanical preparation . All restorations were evaluated blindly by 2 independent examiners using the modified USPHS criteria at baseline , and after 6 , 12 and 24 months . Data were analyzed statistically by Fisher 's exact and McNemar tests . After 2 years , 59 out of 70 restorations were evaluated . As much as 78.8 % retention rate was recorded for RC restorations , while 100 % retention was obtained for RMGIC restorations . Fisher 's exact test showed significant differences ( p=0.011 ) for retention . However , there were no significant differences for marginal integrity , marginal discoloration , anatomic form and secondary caries between the RC and RMGIC restorations . The McNemar test detected significant differences for Excite/TC between baseline and the 2-year recall for retention ( p=0.02 ) , marginal integrity ( p=0.002 ) and anatomic form ( p=0.04 ) . Therefore , the one-bottle etch- and -rinse bonding system/resin composite showed an inferior clinical performance compared to the RMGIC BACKGROUND The authors conducted an in vivo investigation to compare the clinical performance of two commercial one-bottle adhesives and a two-bottle adhesive for restoration of noncarious cervical lesions ( NCCLs ) . METHOD The patient pool consisted of 57 patients and 171 teeth ( three teeth per patient ) , with one NCCL per tooth . Each patient received three resin-based composite restorations , each with a different adhesive : one tooth with a two-bottle , water-based adhesive as the control ; another tooth with a one-bottle , ethanol-based adhesive ; and a third tooth with a one-bottle , solvent-free adhesive . The authors assessed restorations in terms of retention , marginal integrity , margin discoloration and air sensitivity at baseline , six months , one year , two years and three years after initial placement . RESULTS The retention rates at 36 months were 88 percent for the first adhesive , 81 percent for the second adhesive and 90 percent for the third adhesive . No statistically significant differences in retention rates could be shown , with 86 percent of restorations retained overall . Measures of marginal integrity , marginal discoloration and sensitivity also had no statistically significant differences between the three adhesives ( P > .05 ) . CONCLUSIONS All three adhesives performed with acceptable outcomes after a 36-month period , with small differences between the one- and two-bottle systems and between the various solvents . Retention rate was moderately high and air sensitivity was markedly reduced ; however , superficial marginal discoloration and marginal degradation was notable . Certain lesion , tooth and patient characteristics may predispose restorations to retention failure . CLINICAL IMPLICATION S The type of solvent may not be a major factor in retention of Class V restorations in NCCLs . Both single-bottle adhesives and conventional two-bottle adhesives performed acceptably This double-blind clinical trial was undertaken to compare the retention rate of restorative material s with contrasting stiffness in noncarious class 5 lesions . All restorations were placed using retraction cord and cotton roll isolation to more closely mimic the general practice setting . Thirty subjects with at least two lesions were recruited to participate in the study . Each subject received one restoration using Silux Plus and one using Z100 . The assignment of material was r and omized , and the subjects were unaware of which tooth had received which material . All restorations were placed with a fourth-generation adhesive liner , Scotchbond Multi- Purpose . Evaluations were performed at baseline , 6 , and 12 months by two independent examiners unaware of the restoration 's group identity . The restorations were evaluated using criteria developed by Cvar and Ryge in a forced-consensus model . Despite the fact that the two material s have widely different elastic modulus values , after 12 months no difference between the retention rates for the two groups was found , and both groups of restorations performed very well Objective The purpose of this double-blind , r and omised trial was to compare the clinical performance of a hybrid composite ( Clearfil AP-X , Kuraray , Tokyo ) and a nanocomposite ( Filtek Z350 , 3 M ESPE , St. Paul , MN ) over a period of 2 years in non-carious class V lesions using a modified US Public Health Service ( USPHS ) system . Methods Forty-six patients with at least one pair of equivalent non-carious cervical lesions under occlusion and a mean age of 44.1 years ( range 27–66 years ; median 45 years ) were enrolled in this study . A total of 116 restorations ( 58 with each material ) were placed according to manufacturer 's instructions by two calibrated operators . The restorations were evaluated at baseline and at 6 , 12 and 24 months after placement using the USPHS criteria for retention , colour match , marginal discolouration , marginal adaptation , anatomic form , surface texture and secondary caries . Statistical analysis was conducted using the Cochran and the McNemar tests at a significance level of 5 % ( P < 0.05 ) . Results No surface texture changes or secondary caries were detected in association with any restorations . The retention rates for Clearfil AP-X ( 100 % ) and for Filtek Z350 ( 91.38 % ) did not differ significantly ( P > 0.05 ) . Two Z350 restorations were completely lost after 2 years . No significant differences were observed in the colour match , marginal discolouration , marginal adaptation or anatomic form . Conclusions There were no significant differences in the clinical performances between the material s. Clinical relevance Both restorative material s exhibited acceptable clinical performance in class V non-carious lesions 2 years post-restoration UNLABELLED This double-blind r and omized clinical trial compared different ethanol/water and acetone-based systems in non-carious cervical lesions over 36 months . MATERIAL S AND METHODS Eighty-four patients having at least one non-carious cervical lesion [ NCCL ] under occlusion were enrolled in this study . A total of 84 restorations were placed , half for each group ( Adper Single Bond [ SB ] + FiltekA110 or One Step [ OS ] + MicroNew ) . All the material s were placed by two calibrated operators . Two other independent examiners evaluated the restorations at baseline , 6 , 12 , 18 and 36 months , according to slightly modified USPHS criteria . Statistical analysis between material s in each period was conducted using the Fisher 's exact test ( alpha=0.05 ) , and performance of the material s in the baseline in comparison to each period was evaluated by McNemar 's test ( alpha=0.05 ) . RESULTS The 12- , 18- and 36-month retention rates for SB were 95.2 % ( 12 and 18 months ) and 92.3 % ( 36 months ) . For OS , the retention rates were 83.3 % , 73.8 % and 56.4 % , respectively , for each recall period . After 36 months , 10 OS restorations ( 25.7 % ) and seven SB restorations ( 17.9 % ) were rated as Bravo in the marginal discoloration item . CONCLUSIONS The ethanol/water-based adhesive ( Single Bond ) that was evaluated showed a higher retention rate than the acetone-based system ( One Step ) after 36 months of clinical service The dentinal adhesive Scotchbond 2 was evaluated with the microfilled composite resin Silux in cervical and root caries lesions for up to 3 years . Clinical criteria evaluated included retention , marginal integrity , marginal discoloration , color match , anatomic form , recurrent caries , gingival response , and postoperative sensitivity . Overall , the adhesive demonstrated improved performance over earlier dentinal adhesive systems . Retention was greatest at 3 years when available enamel margins had been etched ( 93 % ) and when root caries lesions ( 97 % ) had been restored . Other criteria were reported as generally favorable . Early findings suggest that the level of development of sclerotic dentin may influence behavior of the adhesive . The greatest difficulty was noted in lesions presenting with heavy sclerotic dentin INTRODUCTION The aim of this two-year prospect i ve clinical study was to evaluate and compare the clinical performance of three different adhesive esthetic material s in noncarious cervical lesions . MATERIAL AND METHODS A total of 90 restorations ( 30 per material ) were placed in 30 patients who ranged in age between 18 and 50 years and of both genders , by a single operator with no previous preparation . The restoration of noncarious cervical lesions was done with either a microfilled composite ( Esthet . X/Dentsply/De Trey , Konstanz , Germany , and Prime&Bond NT/Dentsply/De Trey ) , a nanohybrid composite ( TetricEvoCeram/Vivadent , Schaan , Liechtenstein , and AdheSE/Vivadent ) , or a compomer ( Dyract eXtra/Dentsply/De Trey and Xeno III Dentsply/De Trey ) . All restorations were evaluated by independent examiners using a modified US Public Health Service criteria at baseline and after 12 and 24 months for six clinical categories . Data were analyzed statistically by Pearson 's chi-square or the Fisher 's exact test at 5 % significance level ( p<0.05 ) . RESULTS Results showed that most of the restorations were clinical ly satisfactory after 12 and 24 months , with no statistically significant differences among the three groups for all evaluated criteria . CONCLUSION Treatment of noncarious cervical lesions using composite and compomer material s , combined with the appropriate adhesive systems and properly implemented restorative procedures , gives satisfactory results after a two-year evaluation period One hundred fifty-nine noncarious cervical lesions were restored with glass-ionomer cement , resin composite used with a dentinal bonding agent , or the laminate ( s and wich ) restoration , which combines both these material s. These restorations were evaluated at baseline , 1 year , and 3 years for color match , cavosurface marginal discoloration , anatomic form , marginal adaptation , and retention . There was a general deterioration of the restorations with time . Lesions restored with resin composite and a dentinal bonding agent exhibited the highest percentage of lost restorations PURPOSE To place four restorative material s , including two resin-based composites ( Pertac III and Synergy ) , an improved resin-modified glass-ionomer ( Fuji II LC Improved ) , and a compomer ( Dyract AP ) , in Class 5 non-carious cervical lesions and to evaluate and compare those restorations for marginal discoloration , anatomic form , surface texture , secondary caries , retention , and marginal adaptation at baseline and annually for 3 years . METHODS The tested material s were used to restore moderate-size Class 5 non-carious cervical lesions . All material s were used following the manufacturers ' directions for etching , bonding , curing , and finishing . Thirty restorations of each material were placed . After rubber-dam isolation , a bevel was placed on the occlusal margin of all preparations except the Fuji II LC Improved , and all preparations were cleaned with pumice . Each restorative material was placed and cured in increments except Fuji II LC Improved . All restorations were evaluated at baseline , 6 months , 1 , 2 , and 3-year recalls using a modified USPHS scale . RESULTS Analysis with Chi Square and Logit Analysis revealed that , at 3 years , Pertac III and Fuji II LC Improved were significantly rougher than all other material s. Pertac III had significantly poorer marginal adaptation than all other material s. All other comparisons were not significant . At 3-year recall , most restorations were satisfactory
Conclusion The current best evidence indicates that a glass ionomer cement has a significantly lower risk of loss of a NCCL restoration compared to either a three-step etch- and -rinse or a two-step etch- and -rinse adhesive system ; a three-step etch- and -rinse adhesive system has a significantly lower risk of loss of a NCCL restoration compared to a two-step etch- and -rinse adhesive system .
No significant difference could be observed in the risk of loss of a tooth-colored NCCL restoration between a three-step etch- and -rinse adhesive system and either a two-step self-etch or a one-step self-etch adhesive system
Objectives The aim of this review was to assess the effect of different adhesive systems and tooth preparation on the retention of tooth-colored restorative material s  placed in non-carious cervical lesions ( NCCLs ) .
