“…Threshold levels in this study support these statements, as they were lowest at the incisal edges of the incisors for both the fluorotic and non‐fluorotic teeth, and highest at the cervical third. Similar findings have been reported for the anterior teeth in other studies (6,9,10,21) while Jacobson (7) in an in vitro study reported that the middle third electrode placement sites of the labial surface of maxillary incisors had the least resistance.…”

“…There is, however, no consensus on this. Like several others (6,9,10,21), the current study employed the maxillary central incisors. The choice was based on their location and ease of access, reduced incisal edge wear unlike what can be commonly seen with the posterior teeth and the pulp size reduction that follows secondary dentin deposition.…”

The placement site of electric pulp tester (EPT) probe on the tooth affects the threshold values obtained. The aim of this study was to determine and compare threshold levels and appropriate placement sites for EPT probe on fluorotic and normal teeth. Equal numbers of fluorotic and non‐fluorotic maxillary central incisors of 40 subjects were assessed. The mean of three threshold readings from an EPT was taken from the labial surface at the incisal edge, incisal third, middle third and cervical third. Kruskal–Wallis and Friedman ANOVA followed by post hoc tests were used to compare threshold scores. Significantly higher thresholds were recorded for fluorotic teeth at the incisal edge and incisal third. The lowest thresholds were obtained for the incisal edge in both fluorotic and non‐fluorotic teeth when compared to the cervical third. There was no statistically significant difference among corresponding test sites between the genders and age groups.

“…These claims are supportive of the threshold values found in this investigation, which were highest at the cervical third and lowest at the incisal margins of the incisors for both fluorotic and non-fluorotic teeth. Other studies have revealed similar results for the anterior teeth 15,28 . An in vitro study by Jacobson et al only demonstrated the middle third of the labial surface of maxillary incisor teeth to be the site for lowest threshold readings 29 .…”

Introduction: The probe placement site for an electric pulp tester. (EPT) will have a significant outcome for the threshold readings. These relationships in previous studies have been documented. As dental flourosis is an endemic in regions of Pakistan the aim of this study was to compare and determine the appropriate EPT probe placement sites on fluorotic and non flourotic teeth. Methodology: In this cross-sectional clinical study equal number of flourotic and non flourotic maxillary central incisors(40 volunteers) were selected from a known region of Pakistan for endemic of flourosis to measure threshold levels on EPT on four different parts of each tooth. (Incisal edge, incisal third, middle third and cervical third). Before the readings were taken flourotic teeth were also categorized on the bases of severity (Deans Index).The purpose was to assess if severity of dental flourosis had an impact on the EPT readings. Once the mean values were taken the Dunn–Bonferroni post hoc tests was used to assess the statistical significance (p<0.05) between the four site in both groups. Results: Mean values from the EPT presented that the threshold values increased from incisal to cervical in gender and both age groups i.e. 20-29 and 30-40. It was also found that the threshold values increased from incisal edge to the cervical third in flourotic and non flourotic teeth. Statical significance was found between the reading of flourotic and non flourotic groups across the four probe site readings taken (p value= 0.00). Like previous literature the insical edge was considered the most ideal site for EPT assessment on anterior incisors. As this is where the lowest threshold response was recorded in our study .Dental flourosis does have a significant effect on the EPT threshold values. This is most likely due to structural changes because of dental flourosis. Recommendations: From the study conducted it can be recommended that clinicians need to be aware of the fact that fluorotic teeth response will vary from natural teeth on the EPT. Also further research needs to be done to assess if other vitality test methods will also alter in their response due to dental defects like flourosis.

“…In the present study, in both fluorosed and nonfluorosed teeth incisal edge showed lowest threshold levels for EPT when compared to incisal, middle and cervical thirds because the enamel is thinnest incisally with the highest concentration of neural elements in the pulp horns while in the cervical area the number of nerve fibers decrease. [ 31 ] The straight course of dentinal tubules at the incisal edges of anterior teeth offers faster flow rate to the electric current. [ 12 ] This explains why the threshold values were lower at the incisal edge region than in the cervical third.…”

Background:Accurate diagnosis is key to success. Diagnosing the pulpal status in varied clinical situations poses a challenge to the clinician. Electric pulp test (EPT) is one of the valuable attempts in evaluating the sensibility of pulp tissue. The aim of this study was to find out and compare the threshold levels and optimal electrode placement site for EPT in fluorosed and nonfluorosed anterior teeth.Materials and Methodology:Eighty volunteers recruited for this study were divided into two groups based on the incidence of dental fluorosis. Electric pulp testing was done on either of the central incisors in fluorosed and nonfluorosed group. Four sites on each crown were tested 4 times with digitest electric pulp tester, and the mean of the threshold responses was recorded. The data were analyzed with SPSS, version 11. Means of variables from each location were compared using one-way ANOVA and Tukey's post-hoc test while the critical level of significance was set at P < 0.05.Results:The mean and standard deviation of threshold levels in fluorosed teeth were greater when compared to that of nonfluorosed teeth at all sites with incisal edge showing the least mean threshold levels for both the groups (P > 0.05).Conclusion:Within the limitations of this study, it can be concluded that fluorosed teeth respond to higher threshold levels than the non-fluorosed teeth, and incisal edge was the optimal electrode placement site.
