Both chronic kidney disease (CKD) and its treatment can affect a wide range of tissues and systems. It directly or indirectly affects flow, concentrations and composition of saliva. Hemodialysis can effectively minimize most of these complications to some extent.The main aim of this study was to know the salivary content of sodium, potassium, calcium, urea, bicarbonate and oral manifestations in patients with CKD.For this study, 50 patients diagnosed with CKD and 50 systemically and periodontally healthy individuals were subjected to a detailed general and intraoral examination. Whole un-stimulated saliva samples of all the selected subjects were collected and subjected to calcium (Ca), phosphorous (P), sodium (Na), potassium (K), bicarbonate and urea analysis.Paired t-test, Mann-Whitney test.Among 50 study subjects, 26 subjects had reduced salivary flow in the range of 0.1-0.4 ml/min. Intraoral examination of the study subjects revealed pallor, increased deposition of calculus, bleeding gums, metallic taste, hypoplasia of teeth and fissured tongue. There was a significant difference between healthy and prehemodialysis patients in the salivary sodium, potassium, calcium, phosphorus, urea levels and the difference was insignificant in relation to bicarbonate levels.Alterations in salivary calcium, phosphorous, urea, sodium, potassium levels were significantly higher in the study groups when compared to control groups and the difference was insignificant in relation to bicarbonate level. The increased levels in dialysis patients correlated with renal disease severity.

The aim of this study is to evaluate the response of human pulp tissue to mineral trioxide aggregate (MTA), Emdogain (EMD), and combination of MTA/EMD.This study was performed on sixty intact first and second premolars of human maxillary and mandibular teeth. A standard pulpal exposure was done on all the teeth and was divided into three groups of twenty teeth each and was capped with MTA, EMD, and MTA/EMD combination. The final restoration was done with resin-modified glass ionomer cement. The teeth were then extracted on the 15Differences in inflammatory response and thickness of dentin bridge formation of the exposed pulp to the three different groups were statistically evaluated using Chi-square and Mann-Whitney tests and were found to be significant. No significant difference was found between MTA/EMD and MTA in terms of calcified bridge formation and pulp inflammatory response to the capping materials.MTA and MTA/EMD combination produced a better quality hard tissue response compared with the use of EMD.

Zinsser-Cole-Engmann syndrome also called Dyskeratosis Congenita (DKC) is a rare genodermatosis first described by Zinsser in 1906. Mutations in DKC1 gene is responsible for DKC. It is usually inherited as an X-linked recessive trait, resulting in a striking male predilection. It is characterized by a triad of reticular skin pigmentation, nail dystrophy and mucosal leukoplakia. Complications include predisposition to malignancy and bone marrow failure. Here, we report a case of DKC in a 9-year-old boy with classic triad of signs. Special investigations like endoscopy, barium swallow and bone-marrow aspiration study confirmed the diagnosis. There is no effective treatment for DKC. Some preventive measures can be adopted and the only long term cure for the haematological abnormalities is allogenic haemopoietic stem cell transplantation.

Granulocytic sarcoma (GS) is an extremely rare condition involving infiltration of myeloblasts or immature myeloid cells in an extramedullary site. It is also known as chloroma, myeloid sarcoma or extramedullary myeloid tumor. It usually occurs concomitantly with acute myelogenous leukemia or with the onset of blastic phase of chronic myelogenous leukemia. On rare occasions, it evolves even before the onset of leukemias, and when it precedes leukemias without any overt signs, it is referred to as the primary type. Although GSs can involve any body part, localization in the oral cavity is extremely rare. The recognition of this rare primary entity is important because early aggressive chemotherapy can cause regression of the tumor and improve survival. Here, we report a rare case of GS in a nonleukemic 62-year-old female who presented with generalized gingival enlargement involving both maxilla and mandible.

All-ceramic crowns with different core materials of different strength and aesthetics are available in recent years. The aesthetics of the crown depends mainly on the shade and translucency. Clinician should be aware of the quality and characteristics of these materials so that they will be able to opt for good material for successful clinical use.The aim of this study was to evaluate and compare the translucency of crowns fabricated with three different commercially available all-ceramic materials viz. Alumina - CAD-CAM Procera, Lithium disilicate - Pressable IPS e.max Press, Zirconia - CAD-CAM Lava.All-ceramic crowns (5 per each group and total of 15 samples) were made of Alumina - CAD-CAM Procera (Group I), Lithium disilicate - Pressable IPS e.max Press (Group II), Zirconia - CAD-CAM Lava (Group III) and veneered with their respective layering ceramic. Evaluation for the Translucency (CR=Yb/Yw) over the White (Yw) and Black (Yb) backgrounds at the Incisal, Middle, Cervical, Mesial and Distal thirds of each crown were done using the Spectrophotometer. The results obtained were statistically analyzed by Paired t-test (p<0.05) and Analysis of Variance (p<0.05) for the test of significance among the groups.Significant differences in the contrast ratios were obtained among the three Groups (p<0.001). In this study, Group II Lithium disilicate-Pressable IPS e.max Press showed higher translucency (0.54). Group III Zirconia - CAD-CAM Lava showed the least translucency (0.75) and the translucency of Group I Alumina - CAD-CAM Procera (0.7) was in between both the groups.Translucency of material gives fair idea to clinician for the choice of material in different zones during replacement and suitability for restoration in aesthetic zone. Selection of all ceramic system depends on the translucency needed for successful prosthesis of artificial tooth so that it mimics patients natural dentition. The qualitative measurement of translucency will give the evidence for the clinicians during selection of high or low value translucent tooth for successful replacement. Lithium disilicate - Pressable IPS e.max Press is having better translucency in comparison with other two materials in our study.

The purpose of this prospective, randomized, double-blind study was to compare the anesthetic efficacy of 2% mepivacaine and 2% lidocaine (both with 1:80,000 epinephrine) for inferior alveolar nerve block in mesioangular bilaterally impacted third molar extraction.Forty patients with mesioangular bilaterally impacted third molars were taken for the study; either 2% mepivacaine or 2% lidocaine is given in a double-blind manner. Surgery started 5 min after solution deposition. Success was defined as no or mild discomfort (visual analog scale [VAS] recordings) during the surgical procedure.The mean time for onset period 4.2 min and 4.6 min (P = 0.018). The mean duration anesthesia 177.17 min 166.71 min (P = 0.085). No significant difference between the scores of pain reported by the patients by VAS and venovenous bypass treated with mepivacaine and lidocaine (P = 0.000). Slight increased postoperative analgesics required for mepivacaine group (4.000 tablets) and lidocaine group (4.170 tablets) (P = 0.335). The sharp increase of pulse rate with respect to both the solutions at 5 min after postinjection of local anesthetics. However, there was no statically significant difference in systolic and diastolic blood (P = 0.681) and (P = 0.270).Lidocaine and mepivacaine with the same vasoconstrictor have similar action and both solutions are effective in surgical procedures. There were also no significant differences between them in relation to the intensity of postoperative pain.

Epidemiological studies have shown strong evidence that periodontal disease does not affect all subjects in the same manner.There are subjects and sites with higher risk for disease progression. This study tested parameters to select a priori sites and subjects potentially at risk.The data from periodontal clinical examinations of 2273 subjects was used. The clinical loss of attachment was measured in 6 sites per tooth. Using computer software, the patients were distributed into 14 age groups, with intervals of 5 years, from 11 years to greater than 75 years of age. The measure of each site was compared with the average and the median values of the subject age group, with the results indicating site comparative severity (SCS). Three global parameters were calculated: parameter 1 (PI) - percentage of sites with clinical attachment loss > 4 mm; parameter 2 (P2) - percentage of sites with clinical attachment loss j> 7 mm; parameter 3 (P3) - percentage of sites with clinical attachment loss surpassing the median value for the age group by 100% or more.There were 1466 (65%) females and 807 (35%) males. Most subjects had PI, P2 and P3 values less than 30%. Parameter 3 allowed a division of the sample similar to that of Parameters 1 and 2, with the advantage of analyzing the subject in relation to his/her age group. It was suggested that the methodology of SCS is useful for selecting a population with a high disease prevalence, and that cut-off lines between 10% and 20% would be appropriate for using parameter.

To compare and evaluate the bonding ability of resin composite (RC) to three different liners: TheraCal LC (TLC), a novel resin-modified (RM) calcium silicate cement, Biodentine (BD), and resin-modified glass ionomer cement (RMGIC) using an universal silane-containing adhesive and characterizing their failure modes.Thirty extracted intact human molars with occlusal cavity (6-mm diameter and 2-mm height) were mounted in acrylic blocks and divided into three groups of 10 samples each based on the liner used as Group A (TLC), Group B (BD), and Group C (RMGIC). Composite post of 3 mm diameter and 3 mm height was then bonded to each sample using universal adhesive. Shear bond strength (SBS) analysis was performed at a cross-head speed of 1 mm/min.Statistical analysis was performed with one-way analysis of variance (ANOVA) and post hoc test using Statistical Package for the Social Sciences (SPSS) version 20.No significant difference was observed between group A and group C (P = 0.573) while group B showed the least bond strength values with a highly significant difference (P = 0.000). The modes of failure were predominantly cohesive in Groups A and B (TLC and BD) while RMGIC showed mixed and adhesive failures.Hence, this present study concludes that the bond strength of composite resin to TLC and RMGIC was similar and significantly higher than that of BD following application of universal adhesive.
