Abstract:
BACKGROUND:Compared with the conventional composite resin, the 3M Z350 nano-resin has good wear
resistance, physical mechanical properties, and polishing, and exerts a lower irritation to the dental pulp. Besides fil ing materials, a reliable tooth-prosthesis bonding interface is necessary for resin bonded repairs.
OBJECTIVE:To compare the clinical effects of self-etch bonding Adper Easy One and total-etch bonding Single Bond 2 on nano-resin bonding restoration of the anterior teeth.
METHODS:120 anterior teeth with vital pulp, which had defects at the incisal ends and were to be restored with nano resins, were divided into two groups randomly. Two kinds of adhesives, self-etch adhesive and total-etch adhesive, combined with nano-resin were used to restore the teeth. The patients were re-examined immediately, 6 months, 1 year and 2 years after the treatment. The fil ings, teeth and pulps of patients were examined,
including whether the prosthesis and tooth color were coordinated, whether the gap between the prosthesis and the teeth were sealed, whether the surface of the prosthesis was intact with no loose, whether the prosthesis and teeth had no staining and secondary caries, whether the condition of the tooth pulp had hot or cold
stimulation-induced pain.
RESULTS AND CONCLUSION:No significant difference in the fil ing effects was found between the two groups when the patients were re-examined immediately, 6 months and 1 year after the treatment (P>0.05). The pulp
lesions of the self-etching group were fewer than those of the total-etch group 2 years after the treatment (P<0.05). Self-etching group had 1, 6, 0, 2 cases and total-etch group had 0, 2, 1, 2 cases in uncoordinated color, edge seal,
incomplete restoration and secondary caries, respectively. No statistical y significant differences were found in these four aspects between the two groups (P>0.05). The 2-year fol ow up showed a low incidence of pulp lesions and satisfactory clinical performance after 3M Z350 nano-resin working with self-etching bonding system in the nano-resin fil ing of
anterior teeth with vital pulp.
