Nanofilled and conventional resin-modified glass ionomer fillings combined with connective tissue grafts for treatment of gingival recessions with non-carious cervical lesions

Abstract

The aim of this study was to evaluate the clinical root coverage results of subepithelial connective tissue grafts (SCTG) performed on teeth with gingival recessions and non-carious cervical lesions (NCCLs) that were restored with cervical fillings and compare the results of two different filling materials: resin-modified glass ionomer (RMGIC) and nano-ionomer cements (NIC). A total of 54 teeth with Miller Class I gingival recessions with or without NCCLs in 36 patients (28 females, 8 males) were treated with SCTGs. Cervical lesions were randomly treated with RMGIC or NIC restorations. Periodontal clinical parameters, height of gingival recession (HGR), width of gingival recession (WGR), height of keratinized tissue, and dentin sensitivity were measured at baseline and 3, 6, and 12 months postoperatively. HGR and WGR values were statistically significantly reduced at all time points when compared to baseline values in all groups. There were no statistically significant differences between the groups in any clinical periodontal parameter (P > 0.05). The percentage of root coverage at 12 months was 89.5%, 90.1%, and 96.2% in the RMGIC, NIC, and control groups, respectively. Successful root coverage with connective tissue grafts may be achieved on teeth restored with RMGIC or NIC cervical fillings.

Hipersensibilidade Dentinária Associada a Lesões Cervicais não Cariosas: Revisão de Literatura

“…Os casos de LCNC associadas à recessão gengival que foram tratados com cirurgia mucogengival de reposicionamento coronal combinada a enxerto de tecido conjuntivo e procedimento restaurador resultaram em melhora do quadro de hipersensibilidade e das condições periodontais e estéticas (12,24). Além disso, a espessura gengival menor que 2 mm pode ser um fator que esteja associado a presença das LCNC, sendo o enxerto gengival livre uma das possibilidades para aumentar a espessura gengival nesses casos (34).…”

“…Os procedimentos restauradores são alternativas que visam interromper a progressão da LCNC, fortalecendo o remanescente dental, prevenindo o acúmulo de placa e o desenvolvimento da cárie e doença periodontal. Os materiais restauradores comumente utilizados são a resina composta, a resina "flow" e o ionômero de vidro resino-modificado (12,24,26,27). A resina composta foi mais eficiente em relação ao tratamento de hipersensibilidade quando comparado com ionômero de vidro resino-modificado, principalmente entre pacientes jovens.…”

“…A resina composta foi mais eficiente em relação ao tratamento de hipersensibilidade quando comparado com ionômero de vidro resino-modificado, principalmente entre pacientes jovens. Em pacientes mais velhos, os dois materiais tiveram a mesma eficácia (12,(24)(25)(26)(27).…”

Restorative materials for restorations of non-carious cervical lesions: an overview

“…In specific cases, restoration of the site affected by the lesion is necessary 10 . Dursun et al 11 reported in their research that gingival recession and root exposure may be associated with NCCLs and in these cases periodontal treatment is necessary.…”

“…Besides the advantageous properties of GICs, there were improvements in wear resistance and postoperative sensitivity rate compared to conventional GIC. However, they present mechanical failures when used in areas of load concentration 11,16 .…”
