Aim: To find the effectiveness of abdominal muscle exercises on peak expiratory flow rate (PEFR) in college going obese females. Material and Methods:A total of 20 college going obese females were selected based on inclusion and exclusion criteria who did not receive any sort of exercise and went about their daily routines as usual. Abdominal exercise protocol will include crunches, hiprolls, double knee to chest movement, planks, flutter kicks. PEFR was measured using Peak flow meter. The maximum of the 3 similar trials were taken, and the mean of these trials were calculated, which gave us the final pre PEFR reading of each participant. After recording the pre peak expiratory flow rate all participant were given exercises for a period of 3 months, 4 days a week, 3 sets of each exercise with 10 repetitions per set which gives us post PEFR reading. Result: Statistical Analysis was done using paired group 't' test to compare pre and post peak expiratory flow rate, which is statically significant with (p <0.05). The pre intervention peak expiratory flow rate values were (226.50±40.04), whereas post intervention the value was (292 ± 38.61). Conclusion: When the effectiveness of Abdominal exercise on PEFR was checked using Peak Flow Meter, after 3 months of training, they showed significant improvement in PEFR reading. It shows that the Abdominal exercises are significantly effective in increasing respiratory muscle strength. [ABSTRACT FROM AUTHOR]

Aims: The aim of this study is to evaluate the role of three different intraorifice barrier materials on resistance to fracture of obturated teeth with seal-apex sealer. Subjects and Methods: Eighty extracted human single-rooted mandibular premolars were decoronated to approximately similar dimension, and prepared and obturated with gutta-percha and seal-apex sealer. For the placement of different intraorifice barrier materials, the coronal 3-mm gutta-percha was removed except for the control group. The specimens were divided into four groups (n = twenty) on the basis of the intraorifice barrier material used. Group I: Mineral trioxide aggregate (MTA), Group II: Cention N, Group III: Nanohybrid composite, Group IV: Control, Fracture resistance of the specimens was tested. Statistical Analysis Used: It was done by the statistical software SPSS version 16.0. One-way ANOVA followed by Tukey's HSD test and independent t-test was used. Results: Fracture resistance of endodontically treated tooth was significantly affected by the type of intraorifice barrier used (P < 0.001). Conclusions: The use of nanohybrid composite significantly improved fracture resistance followed by cention N and MTA as compared to the control group. [ABSTRACT FROM AUTHOR]

In the current attempt of research, novel method for spectrophotometric estimation of nalidixic acid in tablets using melted niacinamide as solvent was developed. The main objective behind research is to show "SOLIDS ALSO POSSESS SOLUBILIZING POWER". The current study deals with novel spectrophotometric analytical technique for quantitative estimation of nalidixic acid in tablets using melted niacinamide as solvent. According to the theory proposed by Maheshwari, each & every substance possesses solubilising power; substance may be a gas, solid or liquid. Niacinamide imbibes large solubilizing power to nalidixic acid and having approximate solubility more than 80 mg per gm of melted niacinamide (135°C) whereas aqueous solubility of nalidixic acid is 0.21mg/ml at room temperature. Calibration curve of nalidixic acid was plotted by recording the absorbances of standard solutions of drug. The absorbances were observed at 330 nm against respective reagent blanks. The percentage label claims were found very close to 100 (100.93± 1.303 and 99.08±1.764) indicating accuracy of the proposed method. Percentage recoveries estimated by the proposed method are close to 100 (99.91±1.303 and 101.74±1.663) with significant low values of percentage deviation and standard error. Thus, it may be concluded that proposed method is simple, safe and precise and excludes use of toxic organic solvents. [ABSTRACT FROM AUTHOR]

Intrusive luxation of permanent teeth has great psychologic impact on both parents and children and presents clinical challenge for the dentist. Considering the degree of severity of the injury, different clinical modalities for intrusive luxation treatment may be used: passive repositioning, surgical management, and active repositioning by means of orthodontic traction. The main goal of these modalities of treatment is to achieve a guided repositioning of the tooth without the complications like pulp necrosis, inflammatory root resorption and dentoalveolar ankylosis. This paper presents a case report of management of traumatically intruded maxillary incisors with orthodontic repositioning along with endodontic treatment yielding successful treatment outcomes with no postoperative complications.

Brief Background Impaction of permanent incisors due to supernumerary tooth is a rare entity encountered in the clinical practice. Supernumerary teeth can affect the normal position and eruption of adjacent teeth and often require clinical intervention. Early detection of such teeth is most important if complications are to be avoided. The paper presents a case of an 11-yearold boy with an impacted central incisor tooth in the maxillary anterior region and its management. Materials and Methods The two impacted supernumerary teeth which were preventing the eruption of permanent incisor were surgically removed. Combined approach with surgical exposure and the application of an orthodontic force brought the impacted left maxillary central incisor down to its proper position in the dental arch. Discussion Impacted permanent incisor due to supernumerary teeth is often encountered with psychological problems in children. This causes tooth impaction, common oral complications of supernumerary teeth, spontaneous eruption of the impacted maxillary incisors. factors considered for successful alignment of impacted tooth, need for cumulative surgical and orthodontic treatment for aesthetically pleasant and balanced occlusion are subjects that form the discussion. Summary and Conclusions Impaction of maxillary anterior teeth can be a challenging orthodontic problem. Timely recognition, extraction or surgical removal of supernumerary tooth should be the only remedy. The orthodontic intervention for impacted tooth should not be delayed to avoid unnecessary difficulties in aligning the tooth in the arch. [ABSTRACT FROM AUTHOR]

Background :Among the various dental traumatic injuries avulsion accounts for 0.5 - 16% of all traumatic injuries and is most commonly observed in young adolescents . The important factors to be considered while management of avulsed teeth are conservation, preservation, minimal invasion, patient acceptance and cost. Fibre reinforced composite fixed prosthesis is an innovative alternative to the conventional metal ceramic restorations. Here, a clinical technique for immediate interim tooth replacement is being presented, utilizing the clinical crown to assist the clinician in providing an aesthetically acceptable treatment option . Materials & Methods : Fibre Reinforced Composite( Interlig) has virtually no memory, adapts well to the tooth contours of arch, has patented lock stitch leno weave design which effectively transfers forces without transferring them back to the resin and thus serving a key to success. Avulsed teeth can be bonded directly to adjacent teeth utilizing a prefabricated composite resin framework reinforced with polyethylene fibre as a non invasive long-term provisional tooth replacement. This immediate provisional restoration allows for exact repositioning of the coronal part of the extracted tooth in its original intraoral three-dimensional position and thus relieves the apprehension of the patient caused by the sudden loss of an anterior tooth. Results :Acceptable aesthetics were obtained and the result was satisfactory for the patient. Conclusion : The technique is practical, economically feasible, requires limited laboratory support and materials, and can be accomplished in a single appointment. Using the natural tooth as a pontic offers the benefits of being the right size, shape, and color. This particular design allows for exact repositioning of the coronal part of the extracted tooth in its original intraoral three-dimensional position. [ABSTRACT FROM AUTHOR]
