| Objective:The purpose of this paper is to observe effectiveness about calcium phosphate cement paste vs calcium hydroxide/iodoform paste, when performed direct capping after vital pulpotomy of deciduous molars, which accidentally exposed pulp because treatment of deep carie, in order that provide a reference about choicing of capping agent for clinicians. Methods:Select patients met the inclusion criteria totaled96(96teeth) at Children’s Hospital in Urumqi oral dental outpatients from June2011to June2012, included male50and female46, the children ranged in age from4to6years old,an average of5years, included the first molars53,second molars43.Routine preoperative periapical X-ray taken to exclude periapical inflammation and other diseases or absorb. The patients were randomly divided into calcium phosphate cement paste group (experimental group) and calcium hydroxide/iodoform cement paste group (control group) and informed consent of the parents of these children. Experiment on two groups of teeth in the mouth and teeth are part of disinfection, disinfecting wipes, with teeth under local mucosal injection of articaine touch adrenal injection of about0.5ml,markedly after anesthesia, following with75%alcohol swab cavity disinfection, high-speed mobile mortgage net pulp chamber roof a small cotton scrub with saline cavities, separated from the wet again after disinfection, with a sharp spoon to dig a small sterile residual coronal pulp siegen tube mouth excavation clean, thou shalt save alive coronal pulp, with plenty of saline repeatedly washed with sterile cotton ball wipe cavity, hemostasis, if the root canal orifices bleeding more, the available small cotton ball dipped0.1%epinephrine solution placed bleeding at the compression blade, then the experimental group with calcium phosphate cement paste as capping agent, covering amputated pulp covering the control group used calcium hydroxide/iodoform paste, paste thickness covering both are about1mm, and finally with zinc oxide eugenol paste temporarily seal cavity. If there is no pain and other symptoms observed after1to2weeks, then remove the part of the provisional sealant of the nest cave, then with zinc phosphate cement bottom, glass ionomer cements tight filling. periapical X-rays taken after recording, after3months,6months and12months were observed, such as loose teeth, percussion pain, sinus, restorations,occlusal function, pulp vitality. By X-ray, observed beneath capping agent dentin bridge formation, periapical lesions, apical pore formation, root canal and pulp calcification absorption, follow-up study to evaluate the clinical efficacy. Results:All patients without any pain and other adverse reactions during the observation period. The clinical effective rates were94%and97.8%3months after operation,6months respectively were92.0%and95.7%,12months efficiency were92.0%and87.0%, the statistical analysis of the difference has no statistically significant (P>0.05).Conclusion:calcium phosphate cement paste, as a capping agent for primary teeth pulpotomy, after covering the pulp section, can play effectively isolated from external stimuli and retain the residual activity of the purpose of pulp, It is close to the clinical efficacy of calcium hydroxide/iodoform paste, The findings provide more choice of capping agent in pulpotomy surgery for dental clinicians. |
