前牙外伤性脱位再植治疗效果分析

目的 总结前牙外伤性脱位再植治疗效果。方法 对46例共53颗外伤脱位牙进行再植术，术后追踪观察3。5年。结果 脱位牙再植5年成功率88．68％；其中8～12岁组成功率91．11％，且15．56％牙髓活力正常；脱位时间小于2h的牙齿全部生长良好；再植失败牙均在2年内出现松动脱落。结论 牙再植术是脱位牙有效的治疗方法。年龄小的患者和脱位时间短的牙齿成功率较高。脱位时间较长的牙齿也有成功的病例，临床应尽可能给予再植。

牙再植的治疗体会

作者自1986年以来先后用自体牙再植术治疗外伤性离体牙9例、错位扭转S例、牙周病3例,经6—10年不等的临床的观察,外伤离体牙及错位扭转牙的再植,术后获得较满意临床效果。 一般资料 本组共积集处伤性病离体与9例共14颗均为中切牙和侧切牙,离体时间最长12小时,最短半小时,治疗经过:除离体时间半小时的一颗牙创清直接再植,余牙均根充后再植,结果牙齿生长稳固,颜色基本正常,直接再植牙活力正常。本组收集错位牙钳正固位牙与创5颗,结果牙生长稳固,颜色正常牙活力存在。此外本组还收集3例因牙周萎缩、牙槽骨吸收、牙Ⅱ°松动的中印牙行根尖印除,根充,牙槽窝清创再植,结果牙生长差,牙均Ⅱ°松动、上述病例均经6—10年临床追踪。

Prognosis of replanted primary incisors after injuries

Between 1979 and 1997, 58 avulsed primary teeth were treated at the Pedodontic Clinic of Niigata University Dental Hospital. Among these, we replanted six avulsed incisors of four patients and treated two teeth of two patients replanted at other dental clinics. Referring to the clinical records, oral photographs and radiographs, we examined the injury age, cause of injury, condition of tooth storage, length of time until replantation, and also the prognosis after replantation. Three teeth of two cases remained until eruption of their permanent successors, and one tooth of one case remained under observation without extraction. Although the other four teeth of three cases resulted in extraction, no secondary infection was detected due to replantation. The following reasons were suspected for the poor prognosis of the four teeth. One avulsed tooth was not fixed immediately after replantation. One replanted tooth might not have been compatible with the alveolar socket. In the other two teeth, the periodontal vital tissues might have been removed before replantation. It is generally suggested that replantation of primary teeth is not a good option. However, from the present results, it was considered that replantation can be an effectual method when the condition of the avulsed primary tooth is suitable.

The clinical effectiveness of a dentifrice containing triclosan and a copolymer for controlling breath odor measured organoleptically twelve hours after toothbrushing

The objective of this double-blind clinical study was to investigate the effectiveness of a dentifrice containing triclosan and a copolymer, Colgate Total Toothpaste, for controlling breath odor twelve hours after brushing the teeth compared to a placebo dentifrice which did not contain triclosan or a copolymer. Breath odor was evaluated by a panel of four expert judges using a nine-point hedonic scale. Following a baseline evaluation of breath odor, prospective study subjects who presented scores above the threshold value for unpleasant breath odor were stratified by score, and randomized into two treatment groups. Subjects were provided with a soft-bristled toothbrush, and brushed their teeth thoroughly in their regular and customary manner with their assigned dentifrice. Subjects refrained from dental hygiene, breath mints, or mouth rinses for the next twelve hours, after which they were once again evaluated for breath odor. Sixty-three (63) adult male and female subjects from the Mississauga, Ontario, Canada area participated in the study. At twelve hours after brushing their teeth, subjects in both dentifrice treatment groups presented mean breath odor scores which were statistically significantly lower than the mean scores observed at baseline. However, the difference between the mean twelve-hour breath odor scores differed significantly between the two dentifrices. The mean twelve-hour breath odor score for the Colgate Total Toothpaste group was 4.77, which is within the range of values corresponding to pleasant breath odor; the mean twelve-hour breath odor score for the placebo group was 6.05, which is above the value corresponding to unpleasant breath odor. Thus, the results of this double-blind clinical study support the conclusion that Colgate Total Toothpaste provides effective control of breath odor at twelve hours after brushing the teeth.
