Clinical effectiveness of a dentifrice containing fluoride and a citrate buffer system for treatment of dentinal sensitivity.

Four test dentifrices were evaluated in a double-blind investigation to determine their effect on dentinal sensitivity in 87 adult human participants. Baseline data were obtained by patient questionnaire, dental examination and by soliciting subjective responses to controlled osmotic, thermal and tactile stimuli. The four dentifrices were: (1) a placebo dentifrice, (2) a fluoride dentifrice containing 0.1% fluoride, (3) a 2% citrate buffered dentifrice in a pluronic gel and (4) a dentifrice containing 0.1% fluoride and 2% citrate buffer in a pluronic gel. Precipitated silica provided the abrasive for all dentifrices. Dentifrices were supplied to participants on a random basis, and participants were instructed to brush twice daily for 8 weeks. Responses to the three stimuli as accomplished at baseline were obtained at 2, 4 and 8 weeks on 81 participants. A statistically significant stimulus reduction was found between treatment groups to thermal stimulus at the 2-month interval (P = 0.048) and to the tactile stimulus at 2 weeks (P = 0.019). Both the citrate dentifrice and the citrate/fluoride dentifrices demonstrated significant efficiency in reducing sensitivity.

Comparison of two desensitizing agents for the treatment of cervical dentine sensitivity.

Numerous desensitizing agents have been utilized in an effort to alleviate the discomfort associated with cervical dentine sensitivity (CDS). Recently several new tubule-occluding and sealant systems have been marketed for treatment. The aim of this study was to compare two desensitizing agents (ALL-BOND 2 and Butler Protect) in a 3-month clinical study. Ten subjects (6F; 4M mean age 45.1 years (SD 8.81) who had provided voluntary written informed consent participated in a single-blind 3-month clinical study. Subjects were evaluated for tactile (Yeaple probe) and air sensitivity (dental air syringe) together with subjective perception of pain (VAS scores) at 0.5 min, 1, 2 and 3 months. There was an overall trend in reduction of CDS over the study period in all group with no significant differences detected between groups. The results suggested that while subjects reported overall reductions in sensitivity levels, this may not necessarily be substantiated when assessed objectively. Furthermore, there appeared to be a strong placebo effect in this study.

Efficacy of a potassium nitrate mouthwash in alleviating cervical dentine sensitivity (CDS).

Potassium nitrate (KNO3) has been used previously in a dentifrice or gel to alleviate cervical dentine sensitivity (CDS). The aim of this study was to compare a 3% KNO3 Silica/NaF mouthwash with a NaF/silica mouthwash in a 6-week multi-centre double-blind study. 47 subjects (12M; 35F, mean age 36.2 (SD 11.46) years) participated in the study. Subjects were evaluated for tactile (Yeaple probe) and air sensitivity (dental air syringe) together with subjective perception of pain (0-10 scale) at 0, 2 and 6 weeks. Results for Yeaple probe (gm wt) (Wilcoxon paired rank test) between 6 weeks and baseline, were highly significant for both groups. Differences between groups at 6 weeks were statistically significant. Subjective Yeaple probe scores (paired t-tests) between 6 weeks and baseline were significant for both groups. There were no significant differences (unpaired t-tests) between groups over 6 weeks for subjective Yeaple probe scores. Subjective air scores (paired t-tests) between 6 weeks and baseline were significant for both groups. There were significant differences (unpaired t-tests) between groups in favour of the 3% KNO3/Silica/NaF group at 6 weeks. The 2 weeks and baseline results for both groups were the same as reported for 6 weeks and baseline. The results demonstrated that a 3% KNO3/Silica/NaF mouthwash compared to a Silica/NaF control significantly reduced CDS when evaluated by tactile and thermal stimuli. A 3% KNO3/silica/NaF mouthwash would, therefore appear to have therapeutic potential to alleviate CDS.

Prevalence of cervical dentine sensitivity in a population of patients referred to a specialist Periodontology Department.

The reported prevalence of cervical dentine sensitivity (CDS) ranges from 8 to 35%. Detailed epidemiology of the condition, particularly with regard to possible causal factors, is lacking. In particular, no published data appear to exist on its prevalence in periodontal patients. The aim of the present study was therefore to determine the prevalence, distribution and severity of CDS in a population of patients referred to a Periodontology Department of a specialist postgraduate hospital. 507 patients (181 M; 326F, mean age 44.2 (SD 10.31) years) attending a periodontal clinic were assessed for CDS by a questionnaire. The results demonstrated a prevalence of CDS of 84% with no significant gender difference. 71.1% of patients perceived cold as the most common cause of discomfort. A higher prevalence of self-reported discomfort was observed between 40 and 49 years. Of the patients with a reported history of periodontal surgery (34.7%), those treated within 6 months prior to assessment appeared to be more at risk to CDS. Of the patients who received hygienist treatment (88.2%), only 10.5% reported discomfort persisting > or = 3 days after treatment. Generally, patients who complained of varying degrees of discomfort over time (84.5%) did not perceive the condition as severe and consequently did not seek treatment. The prevalence of CDS in these referred patients was very high, suggesting that periodontal diseases and/or treatment effects play a rôle in its aetiology.

Root-dentin sensitivity following non-surgical periodontal treatment.

BACKGROUND, AIMS: Little clinical data exist on the incidence and severity by which root dentin sensitivity (RDS) results from periodontal therapy. The aim of the present clinical trial was to study the degree to which a sample of patients requiring non-surgical periodontal treatment develops RDS. MATERIAL AND METHODS: Alterations in RDS was followed in 35 patients (29-65 years of age) requiring non-surgical treatment for moderate to advanced periodontal disease. Inclusion criteria for participation were need for periodontal treatment in at least 2 quadrants comprising a minimum of 4 teeth with vital pulps, no open caries lesions, no dental treatment in the last 3 months and no ongoing treatment for RDS. Baseline and follow-up recordings included responses of teeth to pain stimuli (directed compressed air) at buccal surfaces as graded by the patient on a 10-cm visual analogue scale (VAS). Periodontal therapy consisted of oral hygiene instruction (OH) followed by supra- and subgingival scaling/root planing by hand and ultrasonic instrumentation of one quadrant per each of the subsequent weeks. Thus, follow-up data included pain assessment after 1-3 weeks of OH alone, and 1-4 weeks post-instrumentation. RESULTS: There was a statistically significant reduction in mean VAS scoring over time in quadrants where only meticulous plaque control had been maintained, while VAS mean values increased significantly after instrumentation (p<0.001). Also the % of subjects reporting higher mean VAS values increased after instrumentation. Changes in mean VAS scores were generally moderate and only 9 patients gave an increase on VAS of >2 cm for 3 or more teeth. A statistically significantly higher increase of RDS was observed for initially sensitive teeth (VAS>0) than for teeth not responding at baseline (p<0.001). Although a reduction in the intensity of RDS could be noticed during the later phase of the 4-week follow-up period after scaling and root planing, the percentage of sensitive teeth remained unchanged. CONCLUSION: The data confirm that meticulous plaque control will diminish RDS problems and that scaling and root planing procedures in periodontal therapy result in an increase of teeth that respond to painful stimuli. However, pain experiences in general appeared minor and only a few teeth in a few patients developed highly sensitive root surfaces following instrumentation.

Clinical evaluation of pulp and dentine sensitivity after supragingival and subgingival scaling.

The exposure of dentinal tubules by the removal of root cementum on scaling procedures has been proposed to be a source of pulp injury and to cause dentine hypersensitivity. The aim of this study was to evaluate the sensitivity of the pulp and dentine after supragingival and subgingival scaling. Eleven patients with periodontally diseased mandibular incisors were selected. The subjects were divided into two groups according to marginal bone loss. The pulp sensitivity was evaluated by an electric pulp test. Dentine sensitivity was evaluated with two forms of controlled stimulations (probe and air-jet) and with a questionnaire. No changes in pulp sensitivity were found after scaling, but a clinically significant increase in dentine sensitivity to probe and/or air stimuli was observed in 6 patients. Five of these were also sensitive to daily life stimuli. A natural mechanism of desensitization seemed to have occurred two weeks after subgingival debridement. This study showed that supragingival and subgingival scaling might cause a more or less transient occurrence of dentine hypersensitivity.

A study of the prevalence and distribution of dentine sensitivity in a population of 17-58-year-old serving personnel on an RAF base in the Midlands.

Previous studies have reported on dentine sensitivity (DS) prevalence in hospital and general practice populations. Results from these studies indicate that perception and prevalence of DS vary depending on the population. The study aimed to determine any major differences in the perception and prevalence of DS in subjects in a military training establishment. Questionnaires from 228 subjects [188 completed by males, 39 completed by females, with one person not indicating their gender of mean age 24.0 years (s.d. 7.16)] were collected and analysed using the Statistical Package for the Social Sciences (SPSS). Fifty percent of the subjects (n=114) claimed to have DS. Yet approximately 30% of the subjects (29.8%, n=68) perceived the condition as a slight problem and approximately 40% of the subjects (40.8%, n=93) claimed it was an occasional problem and approximately 50% (49.1%, n=112) did not seek treatment. Seventeen subjects (7.5%) used a desensitizing paste during periods of discomfort. No clear pattern emerged with regard to seasonal variation in DS although 5.7% (n=13) subjects considered DS to be more of a problem in winter. Only 7.9% (n=18) reported any previous periodontal surgery, consistent with previous studies (12.6 and 15.5%). Of those who received regular scaling (27.2%, n=62), only 23 (10.1%) reported any discomfort following treatment, which did not last >or=5 days. The results indicate that self-reporting of DS was similar to previous reports, although it is of fundamental importance that such studies should be supplemented with a thorough clinical examination to determine more reliable prevalence data.

Comparison of 2 desensitizing dentifrices with a commercially available fluoride dentifrice in alleviating cervical dentine sensitivity.

Previous studies have demonstrated efficacy of desensitizing dentifrices containing strontium acetate/sodium fluoride (SrAc2F) and potassium chloride/sodium monofluorophosphate (KCl/MFP) in alleviating discomfort arising from cervical dentine sensitivity (CDS). The aim of this investigation, therefore, was to determine efficacy of a SrAc2F dentifrice compared with KCl/MFP and a commercially available fluoride dentifrice containing sodium fluoride/sodium monofluorophosphate (NaMFP). Fifty-six patients participated in a 2-center double-blind, 3-way comparative parallel 6-week clinical study. Patients were evaluated at 0, 2, and 6 weeks for tactile (Yeaple probe), air sensitivity (dental air syringe), and subjective perception of pain (VAS scores). Results for Yeaple probe scores (Wilcoxon tests) between 2 weeks and baseline were highly significant for KCl/MFP, significant for NaMFP and nonsignificant for SrAc2F; scores between 6 weeks and baseline were, however, highly significant for all groups. Subjective Yeaple probe VAS scores (paired t-tests) between 6 weeks and baseline were significant for all groups; significance was demonstrated in the KCl/MFP group between 2 weeks and baseline. Subjective air visual analogue scores (paired t-tests) between 2 weeks and baseline were highly significant for all groups. There were no significant differences between groups at any time point. The results of the study demonstrated that the commercially available fluoride-containing dentifrice was as effective as the 2 desensitizing dentifrices in alleviating CDS over time.
