Aim: To evaluate & compare esthetic perception by Prosthodontist as well as patient using QDA (Questionnaire on own Dental Appearance) and PEI (Prosthetic Esthetic Index). Materials and Methodology: The study was conducted on 44 participants, who were evaluated by a single Prosthodontist by using PEI Index, and another questionnaire filled by patients, evaluating their own esthetic appearance by using QDA index. Data was recorded and Spearman correlation coefficient analysis was done. Results: On the basis of Spearman correlation coefficient test, it showed that the R value was 0.374. This value shows weak but positive correlation between PEI & QDA. Conclusion: On basis of the results of the study, it can be concluded that the perception of Prosthodontist and perception of patient both are different but there was weak positive correlation between PEI & QDA.

Various disinfection modalities are available for dental materials; however, acrylic resins are heat sensitive materials and so cannot be autoclaved. Chemical disinfection has immerged as a safe alternative that is least likely to cause severely detrimental changes to the physical properties of the acrylic resin and be simultaneously potent enough to control the growth of Candida albicans which is the most common cause of denture stomatitis and other inflammatory conditions of the oral mucosa following denture us. Recent research has suggested use of Peracetic Acid on acrylic resins, however the potential of the acid at low concentrations in comparison with commonly available commercial chlorhexidine has not been examined at time intervals that simulate clinical, laboratory and household constraints. Therefore, this study was designed to evaluate the effect of 01% and 0.25% peracetic acid in comparison with 2% chlorhexidine at 5-minute, 10 minute and 8-hour immersion in the chemical solutions of acrylic resin specimens contaminated with Candida Albicans. The percentage elimination of C. albicans with 0.1% peracetic acid and 0.25% peracetic acid was 100% after immersion in disinfectant at every time point. While, the percentage elimination of C. albicans with ICPA Hexidine mouthwash was 60%, 70% and 100% after immersion in disinfectant for 5miutes, 10minutes and 8 hours respectively. The difference in reduction of Candida Albicans as compared to control group was significant (p<0.05) in ICPA Hexidine mouthwash, 0.1% peracetic acid and 0.25% peracetic acid. Acrylic resin samples subjected to 0.1% and 0.25% peracetic acid depicted higher levels of disinfection in comparison with ICPA Hexidine (2% chlorhexidine) following all three intervals of time. It can therefore be concluded that peracetic acid even at low concentrations is capable of controlling the proliferation of Candida albicans even at short immersion time intervals.

Aim: This paper highlights a novel method of apical plug formation with a successful outcome. Methods: Clinical examination of the left maxillary central incisor revealed a draining intraoral sinus in the labial vestibule. A radiograph of the tooth 21 showed an obturated root canal with the presence of incomplete root formation and periapical radiolucency. The endodontic retreatment of tooth 21 was carried out under rubber dam isolation. Hydroxyapatite was condensed into the periapical bone defect along with obturation of the apical third of the root canal. The remaining canal space was obturated with thermoplasticised gutta-percha and the access preparation was restored using resin composite. Result: The 1 year-recall radiograph of the patient revealed a successful outcome and the patient was asymptomatic. Conclusion: Condensation of hydroxyapatite into the periapical bone defect, along with biomimetic obturation using hydroxyapatite of the apical root canal system is an innovative approach for the nonsurgical treatment of cases with incomplete root formation.

Context: Probiotics have been prescribed to old aged patients' invariably with or without complete dentures for improving their digestive process. It is mentioned that probiotics do have an effect in increasing the amount of saliva in the oral cavity. Therefore, this study was planned to evaluate the amount and pH of saliva after using probiotics for 60 days in completely edentulous patients. Aim: This study aims to evaluate the amount and pH of saliva of edentulous patients before and after using probiotics. Settings and Design: The interventional prospective study was conducted at the department of prosthodontics of the institute. Methods: The study was conducted on edentulous patients. The whole unstimulated and stimulated saliva was collected at baseline and amount, and pH was measured. Then, each patient was given probiotic capsules reaching 3.3 × 107 CFU/g to consume daily once for 60 days. Saliva was recollected from patients, and its amount and pH was calculated and compared with baseline. Statistical Analysis Used: STATAIC-13. Results: On comparison of saliva before and after consuming probiotics, there was an increase in the mean unstimulated and stimulated saliva from baseline to that after 60 days, the difference being 0.406 and 0.433, respectively. The difference was statistically significant with P < 0.001. The mean pH at baseline was 7.818 ± 0.231 which increased after 60 days to 7.825 ± 0.189, the difference being 0.007. Conclusion: This study concluded that probiotics increase the amount of saliva of completely edentulous patients and so it can be helpful in patients suffering from xerostomia/hyposalivation.

This case study explores the treatment related issues of a 9 year old boy, who presented with symptoms of Panic Disorder with Agoraphobia, School Refusal and depressive symptoms, in a school counseling setting. To cope with anxiety and reintegrate the child within school. Initial three sessions focused on rapport building and exploring the problem using narrative therapy. Next three sessions included narrative therapy techniques and cognitive behaviour therapy including behaviour experiments and graded exposure was carried out to gain confidence over his anxieties and reintegrate him to school environment. Simultaneously family, teachers and peers were counselled to maintain the gains in therapy. At termination the child presented marked decrease in anxiety symptoms, willingness to attend school and engage with classmates, and improvements in self-confidence. The Narrative and Cognitive Behavioural Techniques were found to be effective in treatment of panic disorder with agoraphobia. Family and school support is essential and the treatment gains its effectiveness when all stakeholders come to support especially in a child case. [ABSTRACT FROM AUTHOR]

Anatomic variations in maxillary molars are frequent. These deviations are also one of the major cause for endodontic treatment failure owing to inadequate cleaning, shaping and sealing of root canal system. Diagnosis of such aberrations using newer imaging techniques like cone beam computed tomography is firmly advocated. The present paper highlights the root canal treatment of a rare case of type I canal morphology diagnosed with an aid of cone beam computed tomographic technique. [ABSTRACT FROM AUTHOR]

Every deterministic finite automata can be converted into regular expression and vice versa.Various techniques like Transitive closure method, Brzozowski algebraic and State elimination exist for conversion of deteministic finite automata to regular expression. In state elimination method concept of bridge state, horizontal chopping and vertical chopping are used for obtaining smaller regular expressions from deterministic finite automata. In this research paper, new heuristic is discussed using which a smaller regular expression can be generated. Relationship between the size of deterministic finite automata and size of regular expression is estimated.. [ABSTRACT FROM AUTHOR]
