Effects of glass fiber post-core crowns and cobalt-chromium alloy post-core crowns in restoration of molar teeth residual roots and crowns
Objective To evaluate the effects of glass fiber post-core crowns versus cobalt-chromium alloy post-core crowns in the restoration of molar teeth with residual roots and crowns.Methods One hundred and two patients with residual roots and crowns of molars treated at Shangluo Traditional Chinese Medicine Hospital from January 2021 to January 2023 were selected for the randomized controlled trial.They were divided into a control group and an observation group by the random number table method,with 51 cases in each group.There were 28 males and 23 females in the control group;they were(44.26±4.36)years old.There were 29 males and 22 females in the observation group;they were(44.3 8±4.47)years old.The control group received cobalt-chromium alloy post and core restorations,and the observation group received glass fiber post and core restorations.After one year's follow-up,the restoration effects,restoration success rates,periodontal indicators[sulcus bleeding index(SBI),gingival index(GI),and plaque index(PI)],masticatory efficiencies,occlusal function,levels of IL-6 and TNF-α in gingival crevicular fluid,and adverse reactions were compared between the two groups by x2 and t tests.Results The Likert score and restoration success rate in the observation group were higher than those in the control group[25.02±1.69)vs.(22.16±1.31)and 96.08％(49/51)vs.80.39％(41/51)],with statistical differences(t=9.552;x2=6.044;both P＜0.05).Before the restoration,there were no statistical differences in periodontal index,masticatory efficiency,occlusal function,and levels of IL-6 and TNF-α between the two groups(all P＞0.05).After the restoration,the SBI,GI,PI,and levels of IL-6 and TNF-α in the observation group were lower than those in the control group[(0.61±0.19)vs.(0.98±0.26),(0.64±0.18)vs.(1.45±0.39),(0.82±0.21)vs.(1.38±0.25),(48.46±4.92)ng/L vs.(54.69±5.64)ng/L,and(4.69±1.02)ng/L vs.(5.75±1.14)ng/L],with statistical differences(t=8.205,13.467,12.249,5.945,and 4.949;all P＜0.05).The masticatory efficiency and occlusal function in the observation group were higher than those in the control group[(91.58±7.89)％vs.(86.25±7.65)％and(147.11±13.58)1bs vs.(136.58±12.05)1bs],with statistical differences(t=3.464 and 4.142;both P＜0.05).The incidence of adverse reactions in the observation group was lower than that in the control group[5.88％(3/51)vs.19.61％(10/51)],with a statistical difference(x2=4.320;P＜0.05).Conclusions Glass fiber post-core crowns show better aesthetic results,periodontal health indicators,masticatory efficiency,and occlusal function compared to cobalt-chromium post-core crowns.They also effectively reduce the levels of IL-6 and TNF-α in gingival crevicular fluid and decrease the incidence of adverse reactions.
