| Objective:In this study,SILICONE One Gloss and oxygen inhibitor were used in resin filling treatment in the form of case report,and compared with clinical conventional resin filling methods.Through follow-up observation,the clinical effects of resin restoration in four groups were compared at 6 and 12 months after treatment,and the clinical effects of SILICONE One Gloss polishing wheel and oxygen inhibitor in resin filling were discussed.Methods:According to the order of patients,120 teeth that met the inclusion criteria were randomly divided into 4 groups with 30 teeth in each group.Group A:extra-fine diamond bur;group B:SILICONE One Gloss polishing wheel;group C:extra-fine diamond bur+oxygen inhibitor;group D:SILICONE One Gloss polishing wheel+oxygen inhibitor.Inclusion criteria of cases:1.The dental caries on the occlusal surface of the molars was not more than 1/2 of the dental cusp,and it's superficial or moderate caries,and the occlusal contact with the opposite jaw teeth was normal.X-ray showed that the periodontal ligament was not significantly broadened,and there was no obvious transmission around the apical tissue.2.The affected teeth had no history of treatment,no trauma,no discoloration of the crown,no crack,no wear and no loosening.There was no progressive inflammation in periodontal tissue,no pathological changes in periapical tissue and dental pulp tissue,no spontaneous pain,no obvious stimulating pain,no occlusal pain,and pulp temperature test was the same as that of normal control teeth.4.The patient's general condition and understanding are good,can cooperate with clinical treatment,with good compliance,and sign the informed consent form before the start of treatment.Take preoperative X-ray film of affected teeth,educate patients on oral health,and remove soft dirt and plaque in the lesion area.Under natural light,the affected teeth were naturally moist,and selecting appropriate color.The occlusal conditions of the whole teeth and treated teeth were examined carefully before treatment,and the occlusal contact points were marked with occlusal paper.Use a high-speed turbine to remove the decayed tissue and avoid the sites of bite force.Group A and group C:using extra-fine diamond bur to polish the enamel on the edge of the hole for30s,group B and group D:using SILICONE One Gloss polishing wheel to refine and polish the enamel at the edge of the cavity for 30s.Rinse the cavity thoroughly,isolate the affected teeth with aseptic cotton roll,37%phosphoric acid gel pretreated enamel wall for 30s,rinse 30s with three guns under pressure,immediately replace the dry cotton roll to insulate moisture,small cotton ball absorbs dry water,and sterilize the cavity with 75%alcohol cotton balls and blow dry.Dip the full Single Bond TMUniversal adhesive with a small brush,dynamically smear the cavity 20s and blow gently for 5s until the adhesive is no longer flowing,the surface is a bright water film,and the light is cured for 10s.3M light-cured resin Z350XT was filled and cured in layers.After the last layer of resin filling was completed in group C and group D,the surface and cavity edge of the whole filling body were covered with oxygen blocker,cured by light for 20s,and washed off with water.The occlusal paper was checked for occlusal condition,then modified and polished.The polishing time of each group was controlled at 30s.Intraoral photos were taken immediately after the completion of filling treatment in all patients to compare the clinical status of the filling body at the time of revisit.Instruct the patient to return regularly to inform the patient of the possible situation and matters needing attention after filling treatment.If the filling body breaks or falls off,and the affected teeth have induced pain,occlusal pain and spontaneous pain,they need to be revisited immediately and be treated accordingly.Results:Resin filling for 6 months,there was no significant difference in anatomic form,color matching,marginal adaptation,smooth surface and secondary caries among the four groups?P>0.05?,but there was significant difference in marginal staining?P<0.05?.Group 3 and 4 were significantly better than group 1 and 2.Among them,there were significant differences in 1-3,1-4,2-3 and 2-4 groups?P<0.05?.Clinical observation of 12 months after resin filling:there was no significant difference in anatomic form,color matching and secondary caries among the four groups?P>0.05?,but there were significant differences in marginal staining,marginal adaptation and smooth surface?P<0.05?.Group 3 and 4 were significantly better than group 1 and 2.Among them,there were significant differences in 1-3,1-4,2-3 and 2-4 groups?P<0.05?.Conclution:As a tool of margin polishing,there is no significant difference between SILICONE One Gloss and extra-fine diamond bur in the clinical curative effect of resin filling.The SILICONE One Gloss and extra-fine diamond bur are used in combination with oxygen inhibitor is obviously better than using SILICONE One Gloss polishing wheel and extra-fine diamond bur alone in marginal staining at 6 months,marginal staining,marginal adaptation and smooth surface at 12 months.It is suggested that the use of oxygen inhibitor in resin filling therapy can delay the marginal staining,improve marginal adaptation and maintain good surface smoothness to a certain extent,and can be used in clinic. |
