ABSTRACTObjectives: The aim of this study was to evaluate the efficiency of ozone alone and with a re-mineralizing solution following application on initial pit and fissure caries lesions in permanent molars. Methods: Forty children (9-12 years) having non-cavitated fissure caries lesions on bilateral 40 first permanent mandibular molar teeth were participated in the study. Patients were randomly allocated to 2 experimental groups consisting of 20 subjects. In the first group, ozone was applied once for 40 seconds to the assigned test teeth of each pair. In the second group, ozone was applied once for 40 seconds to the assigned test teeth of each pair with the use of re-mineralizing solution. Progression or improvement of the caries was assessed at baseline, immediately after treatment and at 1-,2-,3-, and 6 month follow-up by comparing the DIAGNOdent values, Clinical Severity Indexes, Oral Hygiene Scores. The results were analyzed statistically by using the Wilcoxon-Test for dependent samples in each group. When comparing different test groups (control and experimental groups) the Friedman S test followed by the Mann-Whitney U test was used. Results: A statistically significant difference was found between all of the control and experimental test lesions in each group (P<.001). However, there was no statistically significant difference between the ozone treated groups and those using the additional re-mineralizing solution (P>.001). Conclusions: Ozone treatment either alone or combined with a re-mineralizing solution was found to be effective for remineralization of initial fissure caries lesions. (Eur J Dent 2011;5:393-399)

Aim: To evaluate the clinical changes in dentin of deep carious lesions in young permanent molars, following ozone application with and without the use of a remineralizing solution, using the stepwise excavation. Study design: The sample included 162 first permanent immature molars, showing deep occlusal carious cavities that were indicated for indirect pulp capping. Teeth were divided into 2 main groups according to the method of ozone treatment. Each group was further subdivided equally into test and control subgroups. Following caries excavation, color, consistency and DIAGNOdent assessments of dentin were evaluated after 6 and 12 months. Results: Regarding dentin color and consistency, no significant differences were observed following ozone application, with and without a remineralizing solution. There were no significant differences between ozone treatment, and calcium hydroxide during the different evaluation periods, except in group I cases after 6 months, concerning the dentin color. The DIAGNOdent values were significantly reduced following ozone application, with or without a remineralizing solution, as well as between test and control cases in group I after 6 months. Conclusions: Ozone application through the stepwise excavation had no significant effect on dentin color and consistency in young permanent molars. DIAGNOdent was unreliable in monitoring caries activity.

Abstract Aim The purpose of this laboratory research was to compare the accuracy of digital and conventional bitewing radiographs in the diagnosis of recurrent caries under class II amalgam restorations. Methods and Materials This study involved 82 posterior intact teeth in which class II amalgam boxes were prepared. Carious lesions were simulated in half of the proximal boxes in the intersection between the facial or lingual wall and the gingival floor or midway between the facial and lingual walls. The other half of each tooth specimen served as a control. The prepared boxes were then restored with a Tytin FC (Kerr, USA) amalgam. The teeth were radiographed in the bucco-lingual direction to obtain images comparable to bitewing. Digital radiographs made with an intraoral CCD sensor and conventional radiography with dental E film were used. Three expert observers evaluated both types of images for the diagnosis of recurrent caries. Results Sensitivity and specificity values for direct digital radiography were 73 and 95 percent at the buccal and lingual line angles, respectively, and 29 and 90 percent at the mid-gingival floor, respectively. These corresponding values for conventional radiography were respectively 63 and 93 percent at the buccal line angle, 61 and 93 percent at the lingual line angle, and 44 and 95 percent at the mid-gingival floor. The total sensitivity and specificity values were 58 and 93 percent for digital radiography and 56 and 93 percent for conventional radiography. The overall accuracy was 76 percent for digital and 75 percent for conventional radiography. No significant difference in specificity or sensitivity was found between the digital and conventional radiography (p=0.104). Separately, no significant difference was seen between the buccal line angle and the mid-gingival floor, but a significant difference was seen between the two methods in the lingual line angle (p=0.004). Conclusion The digital and conventional bitewing radiographs had similar diagnostic accuracy for the diagnosis of recurrent caries. Lesions located at the buccal or lingual line angle were more easily detected than those at the mid-gingival region. Clinical Significance Although there was no significant difference between digital and conventional radiography in the diagnosis of recurrent caries, digital radiography requires less ionizing radiation, making this method of imaging suggested for routine dental practice.

Aim: To determine the site and pattern of deep carious lesion & its consequences on coronal and radicular structures radiographically in primary molars & first permanent molars using IOPA radiographs. Materials and methods: It consisted of 200 IOPA of Deep carious of Maxillary & mandibular of primary (n=100) and permanent molars(n=100) X-rays are collected. IOPA radiographs of Deep carious lesion involving only dentin with radiolucency reaching the inner 1/3 of dentin, clinically cavitated that is RC5 Of the ICMMS criteria were taken. Blinded Radiographic evaluation was done by two persons to rule out inter examiner variability. Results: In primary molars IOPA there was statistically significant difference in Carious adjacent tooth whereas in permanent molars IOPA there was statistical difference in Diffused pattern and lost tooth structures. When compared primary and permanent molars diffused pattern and lost tooth structure showed statistically significant difference. Conclusion: The deep carious lesions definitely lead to loss of crown structure over a period of time and also capable of spread of caries to adjacent teeth due to food impaction & inadequate oral hygiene. Hence leading to loss of function and arch length.

Abstract We aimed to determine whether dye-ehanced quantitative light-induced fluorescence (DEQLF), wherein the porous structure of carious lesions is filled in with a fluorescent dye, can be used to quantitatively and intuitively distinguish between active and inactive carious lesions. To simulate active and inactive caries, lesions were artificially formed on 126 bovine specimens. They were demineralized with 1% carbopol solution for 3 (A3), 5 (A5), and 10 days (A10). Half the specimens in each group were remineralized with 2% NaF (I3, I5, and I10). The specimens were dehydrated for 10 s and dyed with 100-µM sodium fluorescein for 10 s. Images were captured with a QLF-digital 2+ Biluminator. Fluorescence intensity of the lesions (ΔG) between the groups and absolute changes in ΔG (|ΔΔG|) between dehydration and dye penetration were compared using the independent t-test. ΔG in A3, A5, and A10 were higher than those in I3, I5, and I10 (P<0.001). In |ΔΔG| comparisons, dye penetration was 3.1-3.7 times higher than dehydration in the active group (P<0.001), and was 1.7-2.2 times lower than dehydration in I3 and I5 (P<0.05), with no significant difference in I10. DEQLF may be used to clinically evaluate early caries activity, and longitudnally monitor changes in lesion activity.

Adaptation is an important factor for the clinical success of restorations. However, no studies are available evaluating the adaptation of primary crowns. The aim of this study was to compare the adaptation of crowns fabricated by CAD/CAM technology versus prefabricated fiberglass primary crowns. Typodont maxillary central, canine, and mandibular molar teeth were prepared to serve as master dies after the size of Figaro crowns was determined ( n = 10 ). Master dies were scanned with an intraoral scanner, and 10 identical CAD/CAM crowns were fabricated from resin-ceramic blocks. Figaro and CAD/CAM crowns were placed on the corresponding master dies and scanned via micro-CT. Three-dimensional volumetric gap measurements were performed to evaluate the overall adaptation. A total of 255 location-based linear measurements were allocated into 4 categories: marginal, cervical-axial, middle-axial, and occlusal. Statistical analyses were performed with factorial ANOVA, repeated measure ANOVA, and LSD tests ( α = 0.05 ). CAD/CAM crowns showed significantly lower overall and location-based gap measurements than Figaro crowns regardless of tooth number ( p < 0.05 ). For all groups, mean marginal discrepancies were lower than occlusal measurements ( p < 0.05 ). Both crown types showed higher marginal gaps for molar teeth than for canine and central incisors with no significant difference between them ( p > 0.05 ). CAD/CAM-fabricated crowns showed better marginal and internal adaptation than prefabricated Figaro crowns.

INTRODUCTION: A main variant in the mandibular molars is the presence of radix entomolaris (RE) and radix paramolaris (RP) in the mandibular first molars and fused roots in 2nd mandibular molar. Hence, the present prospective study intends to evaluate the prevalence of radix entomolaris, radix paramolaris and molars with fused roots in a local population of Western Nepal. MATERIAL AND METHODS: This is prospective cross-sectional study. The total of 336 patient's mandibular first and second permanent molars having radiological and clinical evidence of pulpal pathology were included in this study. The criteria for the identification of an extra root were justified by crossing of the translucent lines defining the pulp space and periodontal ligaments in the mandibular first molars, and for the mandibular second molars, the outline of the periodontal ligament was followed to see the presence of the fused roots. RESULTS: Thirty nine patients (24 females and 15 males) showed a supernumerary distolingual root (RE) in mandibular first molars and 42 patients (18 females and 24 males) showed mesiolingual root (RP). The prevalence of patients with radix entomolaris was 11.6% (39 of 336), 13.6% for females (24 of 176) and 9.3 % for males (15 of 160). The prevalence of radix paramolaris was 12.5%(42 of 336), 10.5%(18 of 176) for females and 15% (24 of 160) for males. 54 patients (27 females and 27 males) showed C-shaped canals in mandibular molars. The prevalence of C-shaped mandibular molars was 30% for females (27 of 90) and 34.6% (27 of 78) for males. There was statistically no significant difference in the prevalence of entomolaris, paramolaris and C-shaped canals among male and female population. CONCLUSION: Failure to diagnose radix entomolaris, paramolaris and fused root may lead to missed canal and incomplete debridement of canal resulting in compromised treatment outcome. The successful endodontic therapy employed all the roots and canals to be located, cleaned, shaped and obturated.

Background. The aim of this study was to compare the postoperative pain intensity following the root canal preparation carried out with XP-endo Shaper (XPS; FKG Dentaire SA, La Chauxde-Fonds, Switzerland), iRace (iRC; FKG Dentaire SA) and Reciproc Blue (REC Blue; VDW, Munich, Germany) files. Methods. Mandibular molar teeth with asymtomatic necrotic pulps in 69 patients were randomly divided into three groups (n=23). The root canals were prepared using XPS, iRC or REC Blue instruments and obturated using the lateral condensation technique. The patients were asked to record their pain intensity at 24-, 48- and 72-hour and 1-week postoperative intervals on VAS. For intolerable pain after the procedure, ibuprofen (400 mg) was prescribed. Data were analyzed using chi-squared, Friedman, Kruskal–Wallis, and Mann–Whitney U tests. Results. The postoperative pain gradually decreased during the study period in all the groups (P<0.05). No statistically significant difference was found between iRC system and the two other systems at 12-, 24- 48-hour and 1-week intervals (P>0.05). When compared to XPS system, a higher level of postoperative pain was observed with REC Blue system at 24- and 48-hour intervals (P<0.05). Conclusion. The XPS group exhibited less postoperative pain than the REC Blue group at 24- and 48-hour intervals. iRC, XPS and REC Blue systems were found to be similar in terms of postoperative pain severity.

Background . The effectiveness of fissure sealants in caries prevention depends on their long-term retention and ability to stop caries progression. This randomized controlled clinical trial compared the retention rate and cariostatic properties of a contemporary glass-ionomer-based sealant (GIS) versus a resin-based sealant (RS) placed on fully erupted permanent molars in a split-mouth design. Methods. The sealants were placed on fully erupted permanent teeth (8‒12 years of age) in 45 children. The evaluation was conducted after one week and three and six months. Results. There was a statistically significant difference in the retention rate and caries transition between the two groups over a six-month clinical evaluation period. The resin-based sealant group showed a better retention rate than the GIS group (75.56% and 48.88%, respectively). The resin-based sealant was superior to GIS in preventing caries progression. Conclusion. Resin-based fissure sealant with fluoride releasing properties might be preferable in preventing caries progression of incipient non-cavitated carious lesions in fully-erupted teeth.

Back Ground: Hemifacial spasm is one of movement disorder case that commonly found in daily clinical practice. Epidemiological data are very limited, the average prevalence is 11 per 100,000 population, 14.5 per 100,000 in women and 7.4 per 100,000 in men. In Germany, the estimated prevalence is 8000 to 9000 peoples.1 The incidence of women is more than that of men with a ratio of 2:1. Based on Yaltho and Jankovic study in 2011, out of 215 patients, the ratio of men to women was 1:1.8.2 One study in Indonesia also reported that most of the subjects were female (64.7%).3 Treatment with botulinum toxin injections is preferred to microvascular decompression surgery therapy, but this injection is only effective in a few months and quite expensive. This study is the first study to assess the effectiveness of dry needling on clinical improvement of hemifacial spasm compared to standard therapy of botulinum toxin injection.Methods: The study design was quasi experimental. Total of 24 subjects were divided into two groups. The first group underwent dry needling intervention while the other had botulinum injection. Clinical severity before and after treatment in both groups was assessed using Jankovic and HFS7 scores.Results: In dry needling group there were significant differences between Jankovic and HFS7 score at baseline and at week 1, 2, 3 and 4. While in botox group significant differences were also Jankovic and HFS7 score at baseline and at weeks 2 and 4. There were also a significant difference of Jankovic and HFS7 score when we compared dry needling group to botulinum toxin group.Conclusion: Dry needling can be an alternative treatment for hemifacial spasm, although clinical improvements based on Jankovic and HFS7 scores in dry needling group were not as effective as those with botulinum toxin injections.
