Clinical evaluation of combined surgical/ restorative treatment of gingival recession-type defects using different restorative materials: A randomized clinical trial.

ABSTRACT: Background/purpose:An ideal therapeutic procedure for the treatment of gingival recession associated with an NCCL has presented a challenge to clinicians. Various dental materials and surgical approaches have been used to manage gingival recessions associated with NCCLs for the most predictable combined surgical/restorative treatment. The objective of this study was to evaluate the treatment of gingival recessions associated with non-carious cervical lesions (NCCL) using a modified coronally advanced flap (MCAF) in combination with a connective tissue graft (CTG) on restored root surfaces. Materials and methods:Twenty-three systemically healthy subjects, who were positive for the presence of three cervical lesions associated with gingival recessions in three different adjacent teeth, were enrolled in the study. The NCCL were each restored prior to surgery by using one of three different materials: nanofilled composite resin (NCR), resin-modified glass ionomer cement (RMGI) or giomer. The gingival recession defects were treated by CTG. Results:Inter-group differences were not statistically significant for probing depth (PD), relative recession height (rRH), relative clinical attachment level (rCAL), keratinized tissue width (KTW) or keratinized tissue thickness (KTT) (p > 0.05) among the groups at any time. The mean percentage of defect coverage was 71.18 ± 23.16% for NCR + CTG group; 71.33 ± 22.33% for RMGI + CTG group; and 64.23 ± 20.33% for giomer + CTG group at 1 year postoperatively (p > 0.05). Conclusion:The combined surgical/restorative treatments provided successful clinical results. Giomer + CTG may be less effective compared to other groups for treatment of gingival recession associated with NCCL.

Project description:PurposeTo compare the short-term restorative effect and periodontal health status of restorations with different materials in full-crown restoration of mandibular premolar tooth defects.MethodsA total of 105 cases (123 affected teeth) of mandibular premolar tooth defects who visited the Department of Stomatology between January 2019 and January 2020 were selected, of which 58 cases (68 affected teeth) restored with cobalt-chromium alloy porcelain crowns were included in the metal-ceramic crown (MCC) group and 47 cases (55 affected teeth) repaired by zirconium dioxide all-ceramic crowns were assigned to the zirconia crown (ZC) group. The restorative effect, inflammatory factors (high-sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor-α (TNF-α)) and periodontal health indicators (human cartilage glycoprotein-39 (YKL-40), resistin, aspartate aminotransferase (AST), and alkaline phosphatase (ALP)) after treatment, and the occurrence of adverse reactions were compared between the two groups.ResultsThe ZC group outperformed the MCC group in terms of margin fitness, restoration fracture, gingival condition, and color matching. After restoration, hs-CRP and TNF-α were statistically decreased in both groups, while YKL-40, resistin, AST, and ALP were significantly increased; and compared with the MCC group, hs-CRP, TNF-α, YKL-40, resistin, AST, and ALP were lower in the ZC group. The ZC group also scored statistically higher in retention effect, aesthetic effect, masticatory function, voice function, and comfort. Moreover, the ZC group had a higher total effective rate and a lower incidence of adverse reactions than the MCC group, with statistical significance.ConclusionsZirconia dioxide all-ceramic crowns contribute to a better short-term restorative effect in the full-crown restoration of mandibular premolar tooth defects, with little impact on periodontal health and high patient satisfaction, which deserves popularization and application.

Project description:Fabricating method may affect the surface properties and biological characteristics of provisional restorations. This study aimed to evaluate the surface roughness, plaque accumulation, and cytotoxicity of provisional restorative materials fabricated by the conventional, digital subtractive and additive methods. Sixty-six bar-shaped specimens (2×4×10 mm) were fabricated by using provisional restorative materials through the conventional, digital subtractive and additive methods (n = 22 per group). Ten specimens of each group were used for surface roughness and plaque accumulation tests, 10 specimens for cytotoxicity assay, and 2 specimens of each group were used for qualitative assessment by scanning electron microscopy. The Ra (roughness average) and Rz (roughness height) values (μm) were measured via profilometer, and visual inspection was performed through scanning electron microscopy. Plaque accumulation of Streptococcus mutans and cytotoxicity on human gingival fibroblast-like cells were evaluated. The data were analyzed with one-way ANOVA and Tukey's post hoc test (α = 0.05). Surface roughness, biofilm accumulation and cytotoxicity were significantly different among the groups (P<0.05). Surface roughness was significantly higher in the conventional group (P<0.05); however, the two other groups were not significantly different (P>0.05). Significantly higher bacterial attachment was observed in the additive group than the subtractive (P<0.001) and conventional group (P = 0.025); while, the conventional and subtractive groups were statistically similar (P = 0.111). Regarding the cytotoxicity, the additive group had significantly higher cell viability than the subtractive group (P = 0.006); yet, the conventional group was not significantly different from the additive (P = 0.354) and subtractive group (P = 0.101). Surface roughness was the highest in conventionally cured group; but, the additive group had the most plaque accumulation and lowest cytotoxicity.
