BackgroundTo comparatively evaluate the esthetic improvement of white-spot lesions (WSLs) treated by: BiominF, CPP-ACP paste with fluoride & ICON resin infiltration, using Spectrophotometer & Diagnodent.Material and MethodsThe study was done using 72 sound permanent extracted premolars, divided into four groups (18 teeth per group). After taking the ethical approval the study was commenced. WSLs were created on human premolars and randomly assigned to four groups: Group A: Artificial Saliva, Group B: CPP-ACP with fluoride, Group C: BiominF, Group D: Resin infiltration (Icon). The color change (∆E) of each specimen was measured with a Spectrophotometer (VITA Easy Shade Compact), and fluorescence loss (∆Q) was measured by a laser fluorescence device (DIAGNOdent, Kavo, Biberach, Germany), at different time points after treatment: baseline (0 weeks), 2 weeks, 4 weeks, and 6 weeks.ResultsThe ∆E and ∆Q baseline values for the four groups before the treatments did not differ significantly. Icon treatment improved the WSL color significantly and gave the lowest ∆E (5.12± 3.92) & ∆Q (1.64 ±0.72) compared with other treatments at end of 6 weeks (P< .01). In the BiominF and CPP-ACP with fluoride treatment groups, ∆Q & ∆E showed significant recovery compared with the baseline values (P< .05).ConclusionsWithin the limitations of the study, it can be concluded that all the three remineralizing agents used in the study could effectively remineralize artificial enamel caries and showed improvement in color change and fluoresence as compared to the baseline. Therefore they can be effectively used for the treatment of the white spot lesions.

Aim
This study aimed to study the intensity and duration of patients’ pain perception after placement of elastomeric separators and the effects of various methods to reduce the pain.
Materials and methods
Elastomeric separators were placed on either side of first molars in 120 patients which were divided into 4 groups. Patients in group I were control group, group II underwent low-level LASER therapy, group III were subjected to topical anesthetic gel, and group IV underwent TENS (transcutaneous electric nerve stimulation). And then they were asked to measure pain using a visual analog scale (VAS) at 5 intervals of time, i.e., immediately after separator placement, after day 1, day 2, day 3, and day 4.
Results
Turkey's
post hoc
test showed that pain score after immediate placement of separators was found to be the least in the anesthetic gel than that in other groups and pain score was least in the LASER group out of all four groups on day 1, 2, 3, and 4.
Conclusion
It was found that low-level LASER therapy was more effective in reducing pain after placement of elastomeric separators.

Introduction The aim of this study was to evaluate the validity of Ramanujan’s equation in measuring arch perimeter on untreated natural dentition models and their orthodontically corrected posttreatment models. The secondary objective was to apply the equation to predict the arch perimeter gained by the expansion of the molar teeth or proclination of the incisor teeth and compare it with the actual posttreatment arch perimeter changes. Methods 32 maxillary and mandibular (16 pretreatment and 16 posttreatment each) fairly aligned diagnostic casts of orthodontically treated nonextraction patients with class I molar relationships were used. The arch perimeter was measured using 0.012 mm stainless steel wire and was compared with the calculated arch perimeter obtained using Ramanujan’s equation. Pearson correlations were used to determine the correlation between the measured and predicted values. Paired t-tests were used to assess changes in different variables in the pre- and posttreatment study casts of maxilla and mandible. Results Positive correlation of 0.06 (90% CI) between predicted and measured values was found. In maxillary ( P = .04) study models, predicted arch perimeter by use of Ramanujan’s equation was more reliable than mandibular ( P = .74) study models. Conclusion Ramanujan’s equation can be an important aid to calculate the arch perimeter change by the expansion of molar teeth and proclination of incisor teeth 0.06 (90% CI). It is helpful for more accurate nonextraction treatment planning before the start of orthodontic treatment. In maxillary ( P = .04) study models, calculated arch perimeter using Ramanujan’s equation is even more reliable than mandibular study models ( P = .74).
