In vivo study on the effectiveness of a lacquer containing CaF2/NaF in treating dentine hypersensitivity

The purpose of this double-blind study was to evaluate the effectiveness of a commercially available fluoride lacquer (Bifluorid 12) containing CaF₂ (6%) and NaF (6%) in reducing dentine hypersensitivity. A fluoride lacquer containing only NaF (6%) served as a control. Twenty-five adult patients complaining about at least two hypersensitive teeth participated in this study. In each patient and at each appointment, one tooth was treated with Bi-fluorid 12, while the other was treated with the control substance. Sensitivity levels were determined before and after the application of each lacquer at baseline as well as at 1, 2 and 3 weeks after the start of study. The final evaluation of hypersensitivity was performed at 4 weeks, and follow-ups were undertaken at 6 and 12 months. A reproducible air blast stimulus and a visual analogue scale were used for evaluation. Results demonstrated a distinct reduction of hypersensitivity after 1, 2 and 3 weeks in the Bi-fluorid 12 group. Initially, no obvious effects could be observed in the control group. However, a clear alleviation could be observed after 2 and 3 weeks with the control. After 4 weeks, the overall sensitivity scores were comparably low, without any significant differences between the two fluoride lacquers. In both groups, the effects of treatment were seen over the 12-month observation period. Bifluorid 12 was considered at least comparable to the control. It is concluded from this study that Bifluorid 12 is effective in the initial reduction of dentine hypersensitivity. The combination of CaF₂/NaF can be recommended for clinical use.     

氟化泡沫对减轻洁治后牙本质敏感的近期效果

目的观察牙周洁治后使用氟化泡沫对减轻牙本质敏感的效果,以期为临床提供参考。方法采用随机、对照、双盲的设计。203例需要进行牙周洁治的中重度牙周炎患者,随机分为实验组和对照组,实验组102人洁治后涂擦氟化泡沫;对照组101人洁治后涂擦相同厂家生产的不含氟的对照泡沫。用视觉模拟评分法（visualanalogue scale,VAS）对患者的牙齿敏感程度进行评估。分别于洁治前、洁治后1周和1个月记录VAS值,比较治疗后与治疗前的差值。结果对照组洁治后1周VAS值比洁治前增加（0.75±0.14）;实验组洁治后1周VAS值比洁治前减少（0.41±0.18）,两组间VAS变化值的差异具有统计学意义（P〈0.01）。实验组洁治后敏感程度增加的患者发生率（25.5%）显著低于对照组（40.6%）（P=0.026）。敏感程度明显加重（VAS值增加3以上）患者的发生率（6.9%）也显著低于对照组（21.8%）（P=0.003）。结论氟化泡沫能够降低洁治后近期牙齿敏感的发生率,提高患者牙周洁治后的舒适度,临床指导意义受短时效果所限。     

Effectiveness of arginine-containing toothpastes in treating dentine hypersensitivity: A systematic review

Objectives

To evaluate by way of a systematic review the effectiveness of arginine-containing desensitising toothpastes in comparison to control agents in reducing dentine hypersensitivity.

Data sources

Electronic databases were searched including: Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, LILACS (30/03/2012). Reference lists of eligible studies and systematic reviews were cross-checked in an attempt to identify additional studies. Strategies to identify grey literature were employed.

Study selection inclusion criteria

Controlled Clinical Trials (CCTs) and Randomised Controlled Trials (RCTs) comparing arginine-containing desensitising toothpastes to non-arginine-containing control toothpastes.Two review authors independently screened the titles and abstracts of studies identified. Data collection forms were completed for included studies.

Outcomes

Changes in sensitivity to tactile and air-blast stimuli. A subjective assessment of sensitivity was also sought.

Conclusion

Data identified indicates a potential role for arginine-containing toothpastes in managing dentine hypersensitivity. However, this conclusion is based on small sample sizes and the studies identified did not follow patients up in the medium to long term. The authors recommend that there is a need for well-designed RCTs to be conducted prior to any definitive recommendations being made.

Clinical significance

Dentine hypersensitivity is a common condition. Its multi-factorial aetiology has led to several treatment modalities being advocated. The continued introduction of new desensitising agents suggests that no product has yet proven ultimately successful. Arginine-containing toothpastes have recently been introduced, this article systematically reviews the evidence relating to their effectiveness.     

A 3-day randomised clinical study investigating the efficacy of two toothpastes,designed to occlude dentine tubules,for the treatment of dentine hypersensitivity

Objectives

A product comparison study to compare the short term clinical efficacy of a strontium acetate/silica toothpaste with an arginine/calcium carbonate paste for pain reduction in dentine hypersensitivity.

Methods

The study was examiner blind of two arm parallel design. Eighty healthy adult subjects from general dental practice with ≥2 sensitive teeth but otherwise good oral health, were enrolled and randomised to 1 of 2 toothpaste treatments, schedule provided by the sponsor. Almost equal numbers received each treatment. Tooth sensitivity was measured in three ways; evaporative (Schiff score; Visual Analogue Scale) and tactile stimuli (Yeaple probe), prior to and immediately after subjects’ self application of a single pea sized dose of toothpaste, and following subsequent twice daily brushing for three days with the paste.

Results

All 80 subjects completed the study. Results confirm that for both treatments, pain was reduced immediately and relief was sustained after 3 days use. For all 3 measures, benefit was similar between the two pastes, with no statistical or clinical difference demonstrated, apart from response to evaporative stimulus at 3 days, where Schiff scores were significantly lower in the arginine group, p = 0.02.

Conclusions

It can be concluded that both desensitising, occluding toothpastes provided reduction of pain from dentine hypersensitivity on a short term basis: toothpastes appearing to be clinically similarly effective both after a single subject dab on application and post twice daily brushing for three days.National Research Ethics Service register number 09/H020/57.     

Treatment of dentinal hypersensitivity using a dentine bonding system

AIMS AND OBJECTIVES: Many agents have been used in treatment of dentinal hypersensitivity in the past, but dentine bonding systems have recently been suggested as being effective. This study examined the effectiveness of a dentine bonding system in the treatment of dentinal hypersensitivity in dental practice conditions. METHODS: Dentists in two dental practices agreed to carry out the project. One practice was in the UK, the other in India. A total of 34 patients who were diagnosed to have dentinal hypersensitivity were treated using the dentine bonding system. Patients were requested to record their perception of their pain on a 100mm linear scale, pre-treatment, one day and one week post-treatment. RESULTS: All patients experienced relief of pain, both 1 day and 1 week after treatment. Profile plots of the patients' perceived pain scores for the two practices separately indicated that there was a general trend across both practices for these to fall quite sharply one day after treatment and then generally level out one week post-treatment. There was evidence indicating a possible difference in pain perception in the two communities from which the patients were drawn. CONCLUSION: The dentine bonding system evaluated was successful in reducing the pain of dentinal hypersensitivity, at least in the short term.
