One-year clinical evaluation of tooth-colored materials in non-carious cervical lesions

Abstract

The purpose of this study was to assess the clinical performance of bonded composite (Excite/Tetric Ceram - Vivadent) versus a resin-modified glass ionomer cement (Vitremer - 3M) for restoring non-carious cervical lesions. A total of 70 restorations (thirty-five per material) were placed in 30 patients, 18-50 aged, by one operator. Rubber dam was employed in all cases, lesions were pumiced, enamel margins were not beveled, and no mechanical retention was placed. The restorations were directly assessed by two independent evaluators using modified-USPHS criteria for six clinical categories. The ratings for clinical acceptability restorations (alfa plus bravo) were as follows (Tetric Ceram/Vitremer): retention (86%/100%), marginal integrity (100%/100%), marginal discoloration (100%/100%), wear (97%/100%), postoperative sensitivity (100%/100%) and recurrent caries (100%/100%). Statistical analysis was completed with Fisher's exact or Pearson Chi-square tests at a significance level of 5% (P<0.05). Results showed that almost all restorations were clinically satisfactory with no significant differences between materials groups. Five restorations of Excite/Tetric Ceram failed. No restorations of Vitremer have yet failed.

Four-year randomized clinical trial of oxalic acid pretreatment in restorations of non-carious cervical lesions

“…Analyzing marginal integrity, marginal discoloration, postoperative sensitivity, caries, and anatomic form, the authors had 100 % of success at the 4-year recall, in agreement with other clinical trials [37][38][39][40]. There were no statistically significant differences between treatments, and both were significantly important in reducing dentin hypersensitivity.…”

Dentin hypersensitivity treatment of non-carious cervical lesions – a single-blind, split-mouth study

“…19 Thus, T3's results may reflect the effect of the gel on dentin permeability and nervous excitability, and the restorative technique could block the dentin fluid flow with the composite acting as a mechanical barrier against thermal stimuli. 20 In the case of T4, the latter effect can be hypothesized.…”

One-year clinical evaluation of tooth-coloured materials in non-carious cervical lesions

“…Za evaluaciju i vrednovanje retencije (R), pojave marginalne pukotine (IPK), marginalne prebojenosti (IPR), trošenja (TI), postoperativne osetljivosti (PO) i pojave sekundarnog karijesa (SK) korišćeni su modifikovani USPHS kriterijumi [6] (Tabela 1), pri čemu je ocena A (Alfa) označavala najvišu ocenu, ocena B (Bravo) srednju ocenu, a ocena C (Charli) najnižu ocenu. Za registraciju ocena korišćeni su namenski obrasci u koje su beleženi: ime i prezime pacijenta, zub na koji je postavljen ispun, grupa ispitivanog materijala i kriterijumi za ocenu kvaliteta ispuna: R, IPK, IPR, TI, PO, SK sa ocenama A (Alfa), B (Bravo) i C (Charli).…”

“…Konstantna pojava novih estetskih restaurativnih materijala na tržištu diktira i dužinu kliničkih ispitivanja, koja ne mogu biti dugotrajna jer do isteka kliničkog perioda evaluacije proizvođači plasiraju nove "usavršene" verzije istih adhezivnih sistema i estetskih materijala. Rezultat je sve više jednogodišnjih kliničkih studija koje se bave procenom kvaliteta estetskih restaurativnih materijala, pri čemu se napominje da je za potpunu procenu kvaliteta i dugotrajnosti dentalnih materijala u uslovima oralne sredine ipak potreban duži evaluacioni period [6,9,10].…”

“…U kliničkoj studiji terapijskog učinka kompozita i smolom ojačanih glasjonomera u sanaciji NCCL koju su sproveli Santiago i saradnici [6] znatan broj ispuna je nakon evaluacionog perioda od 12 meseci dobio ocenu Bravo (prisustvo ivične pukotine, pri čemu stomatološka sonda zapinje), što autori povezuju s činjenicom da nije vršeno zakošavanje gleđnih prizmi, to jest s pojavom pucanja gleđnih rubova kaviteta i/ili materijala za vreme procesa polimerizacije. Po mišljenju istih autora, i pored dobre adhezije ispitivanih materijala, narušavanje marginalnog integriteta nastaje i kao rezultat fleksije (saniranih) zuba u funkciji, te stvaranja lokalizovanih defekata na rubovima kaviteta/ispuna.…”
