C-reactive proteins (CRP) levels are usually increased in case of chronic inflammatory process like periodontitis. Association of CRP with pregnancy has been observed in the past, which includes most commonly preterm delivery, preeclampsia, etc. Therefore, it can be hypothesized that CRP may act as a link between periodontitis and adverse pregnancy outcomes. Hence, we aim to evaluate the plasma CRP levels in pregnant women with and without periodontal pathologies. Materials and methods: The study included 210 pregnant women who reported to the hospital with periodontal problems and for routine checkups. All the patients were divided into three groups based on the presence and absence of periodontal pathologies. Russell's Periodontal Index Score was used for the evaluation of periodontal status of the subjects. Results: While comparing the mean CRP levels in all the three study groups, statistically significant results were obtained.

One such procedure is bleaching that offers various advantages, as it is minimal invasive and cheap option to color the teeth and remove stain. The altered enamel after the bleaching process shows surface demineralization and porosities. The present study aimed to evaluate the effect of different bleaching agents on the microhardness of enamel. Materials and methods: A total of 100 freshly human extracted maxillary premolar teeth were selected for the study. Teeth with sound tooth structure were included for the study. All the specimens were randomly divided into four groups with 25 specimens in each group depending upon the type of bleaching agent used: Group A, artificial saliva (Control group); Group B, 35% hydrogen peroxide (HP); Group C, 25% HP; Group D, 10% carbamide peroxide (CP). Knoop Hardness Number (KHN) was calculated at 24, 48-hour, and 7-week interval. Results: Results showed no statistical significant differences between the microhardness of enamel of different groups

[1] The healing process of a wounded, diseased or an injured bone is a normal phenomenon. It begins with fibrin clot formation that alters the normal flow of blood and feeds and supports the osteoprogenitor cells. [2] Successful implant insertion occurs in human bone due to optimum osseointegration at the junction or interface of bone and implants. [3] Most common form of malignancy occurring in humans is the head and neck cancer with over 0.5 million new cases occurring every year. The treatment modality for malignant lesions involves most commonly surgical intervention in combination with radiotherapy. Since, surgical therapy for cancer patients' results in loss of considerable amount of tissue, oral rehabilitation by artificial prosthesis, implants, etc., is a necessary procedure to redress both functional and esthetic disabilities. Artificial prosthesis has certain side-effects such as having the capability of producing xerostomia, mucositis, and altering the healing process in irradiated tissues. Dental implants avoid these side-effects to a much extent but successfully placing implants in patients treated for oral cancer is itself a difficult task because some have had radiation exposure in the tissues. [4] Patients exposed to radiotherapy for treatment of cancer have reduced healing capacity due to progressive fibrosis of vasculature. Radiation

The increased fluoride content is thought to result in a metabolic alteration of ameloblasts, which results in defective matrix, and improper calcification of teeth. A total of 6244 patients between the ages of 6yrs to 60yrs, who presented to our outpatient clinic from October 2009 to December 2010 were included in the study. The study subjects were grouped according to their age into the following groups- 6-14 yrs, 15-25 yrs, 26-40 yrs, and 40-60yrs. Only permanent dentition was taken into consideration in this study. The overall prevalence of fluorosis in this study was 63.34% (3955 of 6244 patients). Men had a slightly higher prevalence of 64.27% compared to 62.28% among women. Prevention of fluorosis would require efforts at raising awareness among the people about the harmful effects of their dietary choices on their teeth. They also need ...

These are tall claims and have potentially difficult repercussions for those behind these machinations if proved. Nevertheless, before those responsible for the mayhem are brought to the books in any foreseeable future, it might be necessary to understand under what circumstances such actions may become ‘rational’ and how these actions are ‘rationalised’ to those in stupor. This understanding would contextualise such phenomenon to develop an informed opinion on these cases. In this regard, this study may be considered as an exercise to explore the relevant contemporary events to this end.

Research paper thumbnail of Evaluation of Clinical Co-Relation of Xi Point (Mid Point of Ramus) in Edentulous Patients with Reference to Occlusal Plane

The conformity to this occlusal plane orientation by other parts of masticatory system is very distinct but it is often missed. It is very important to understand this interrelationship, because slight variation from this desired configuration can lead to occlusal instability. According to GPT 8 [1] occlusal plane defined as "an average plane established by the incisal and occlusal surface of teeth. Generally it is not a plane but represents the planar means of the curvature". Another definition defines as "the surface of wax occlusal rims contoured to guide in the arrangement of denture teeth". In completely edentulous condition the orientation of occlusal plane is lost due to the loss of natural teeth. The determination of correct occlusal plane inclination is necessary during the construction of complete denture in order to get the denture maximum stability and harmonious relation with masticatory system [2]. It is desirable to establish the occlusal plane in complete denture as it was present in natural dentetion [3]. Study design Introduction: In this clinical study the occlusal plane was established by two methods, in first method extra oral landmarks i.e. superior ala-tragal line is used as a reference for establishing the occlusal plane , and in second method intra oral landmarks, commissure of the mouth and upper third of retromolar pad were used as a reference to establish the occlusal plane. And later through digital cephalometric radiograph and DICOM software the proximity of the occlusal plane to Xi point is checked. Materials and Methodology: Occlusal plane was traced up to the full width of ramus, parallelism of occlusal plane to ala-tragal line is verified and the distance between the Xi point to the occlusal plane was measured using DICOM software. Results: The T-test comparison was done between control and study group. Occlusal plane established by method A method B was compared it shows the T-value of-15.470 and P-value of 0.0001. Conclusion: During the construction of complete denture the position of occlusal plane established by considering the superior alatragal line is similar to the position of OP of natural dentition. Material and Methodology This clinical study was performed in dentate and edentate individuals to find out the correlation between the occlusal plane and Xi point(mid point of the ramus) (Figure 1).

Literature has a paucity of the studies that stress on the division and analysis of the pulp canal segments. The reason for this disparity might be the technique used for collecting the samples from the pulp canals. Hence, we carried out the present study to evaluate the microbial flora in the apical part of the roots with necrotic pulp canals. Materials and methods: The present study included the assessment of 40 freshly extracted teeth that had necrotized pulpal tissue along with the presence of periapical periodontal lesions. Removal of the soft tissue lesions attached to the root portion of the teeth along with apical periodontal lesions was done with the help of scalpel blade, after rinsing them with a sterile solution of saline. Thorough cleaning of the root surfaces was done with hydrogen peroxide followed by rapid disinfection with the help of sodium hypochlorite at varying concentrations. Sectioning of the root portion of all the specimens with the help of a disk was done perpendicular to the long axis of the teeth at a distance of roughly 5 to 6 mm from the teeth's apicalmost point. Cryotubes were used for transferring the specimens of apical portions containing 1 mL of buffer and were subjected
