BACKGROUND: Permanent tooth avulsion is one of the severe forms of dental traumatic injuries. The immediate action taken at the site of the accident is crucial to the prognosis of the tooth. Replantation is considered as the treatment of choice. OBJECTIVE: The study was undertaken to assess the knowledge of parents who accompany their children to the pediatric dental clinic, KATH on the pre-hospital management of avulsed permanent tooth in children. METHODS: A researcher administered structured questionnaire was used to collect data on the knowledge of pre-hospital management of avulsed permanent tooth from 83 parents who accompanied their wards to the pediatric dental clinic at KATH. RESULTS: A total of 83 parents were involved in the study. 30 (36%) were males while 53 (64%) were females. The majority of the parents (57%) were either university trained or had attended college of education. Only 32 parents (39%) were aware of the possibility of replantation. Majority of the parents chose non-physiologic media as the transport media of choice and only 10% would attempt self-replantation before seeking professional help. 76 parents (92%) had no previous education on pre-hospital management of avulsed tooth. CONCLUSION: The results obtained from this study indicate that parental knowledge on pre-hospital management of avulsed permanent tooth is low hence the need for massive public educational campaigns.

对分离于甘肃省民勤县的6株木霉菌进行耐盐性筛选和鉴定。结果表明,随着NaCl浓度(0 to 150 mmol/L)增加显著降低6株木霉菌(TG1 to TG6)的菌落直径。与其他5株木霉菌相比,不同浓度NaCl胁迫下菌株TG1具有较强耐盐性。当NaCl浓度为50 mmol/L时,培养2 d后菌株TG1产孢量和菌落直径与对照相比无显著差异,但是其孢子萌发率增加10.59%。菌株TG1在PDA培养基上菌落正面呈暗绿色,菌落背面呈暗黄色,分生孢子球形至椭圆形。分生孢子梗直角分枝,结合其形态特征将菌株TG1鉴定为***。构建菌株TG1的TEF和ITS系统发育树,结果表明菌株TG1的TEF和ITS序列分别与*** IMI 297702(EU401578.1)和***(MT889709.1)序列相似性为99.22%和100.00%。因此,结合形态特征和分子生物学分析将菌株TG1鉴定为*** TG1。与对照相比,菌株TG1在50、100和150 mmol/L NaCl胁迫下产生IAA浓度分别为1.25、1.35和1.56μg/mL,而对照为0.92μg/mL。同时,在50、100和150 mmol/L NaCl胁迫下,TG1菌株ACC脱氨酶活性分别为0.1、0.16和0.17μmolα-ketobutyrate mg/h,而对照为0.09μmolα-ketobutyrate mg/h。
