ABSTRACT
To assess calcium and phosphate loss from enamel using 37.5% hydrogen peroxide (HP) gel with additional application of light emitting diode (LED), Diode laser and Nano-Pulsed Cold laser (NPCL) light sources compared to that of 37.5% HP alone using atomic absorption spectrophotometer (AAS). Methods: Twenty teeth were sectioned to obtain mesiobuccal, distobuccal, mesiopalatal and distopalatal specimens. The specimens were randomly assigned to four equal groups. 37.5% HP of 1mm thickness was applied to the enamel surface of each specimen. Each group received three cycles of bleaching of 8 minute’s duration. Group II, III & IV received additional application of LED, Diode laser & cold laser light respectively. Results: Data was analyzed by means of descriptive statistics. Group III showed the maximum loss of ions while Group IV showed the least loss and the differences were statistically significant (P < .05). Conclusion: Teeth treated with 37.5% hydrogen peroxide with application of Nano-Pulsed Cold Laser (NPCL) light presented with significantly minimal calcium and phosphate loss
ABSTRACT
Background: Aim: to evaluate the effect of bioceramic sealers on post endodontic pain following single visit endodontics. Methods: Ninety patients requiring endodontic treatment were selected for the study. Patients were treated in single visit endodontically using three different bioceramic based sealers. Results: No significant difference was found in post endodontic pain scores between the sealers groups. Conclusion: Any of the three bioceramic sealer can be used forsingle visit endodontics without fear of post operative pain.
ABSTRACT
Background: Aim: To evaluate the effect of diode laser with maleic acid and ethylenediaminetetraacetic acid (EDTA) on the smear layer removal from root canals. Methods: A total of 160 mandibular premolars were decoronated to working the length of 12 mm and prepared with protaper gold rotary files up to size F3. Group 1 canals irrigated with 1 ml 17% EDTA followed by 3 ml of 3% NaOCl. Group 2 canals were initially irrigated with 0.8 ml of 17% EDTA the remaining 0.2 ml was used to fill the root canals, and diode laser application was done. Group 3 canals were irrigated with 1 ml of 7 % maleic acid followed by 3 ml of 3% NaOCl. Group 4 canals were irrigated with .8 ml of maleic acid and remaining .2 ml was used to fill canal and activated by diode laser followed by 3% NaOCl. Scanning electron microscope examination of canals was done for remaining smear layer at coronal middle and apical third levels. Results: Maleic acid with and without diode laser had the least smear layer scores. Conclusion: Diode laser with maleic acid performed significantly better than EDTA.
ABSTRACT
Aim: The aim of this study is to evaluate the effect of low-level laser irradiation and ibuprofen in reducing the onset and severity of postoperative pain following single visit endodontics. Materials and Methods: One hundred and twenty patients were recruited for this study. Group A (n = 30) patients were administered 400 mg of ibuprofen orally 1 h before the institution of an endodontic procedure. Group B (n = 30) patients were given irradiation of a low-level laser at 50 Hz for 3 min after the standard endodontic procedure at the periapical region on both buccal and lingual aspect. Group C (n = 30) patients were given preoperative ibuprofen followed with a low-level laser at 50 Hz for 3 min after endodontic treatment. Group D (n = 30) patients were administered no preoperative ibuprofen nor low-level laser irradiation after the endodontic procedure. The patient immediately recorded his/her pain perception on the Heft Parker pain survey after completion of the appointment and at 4, 8, 12, 24, and 48 h postoperatively. Inter group analysis was carried out using the analysis of variances with “least significant difference” post hoc test. For intra group analysis, Student's t-test was used. Chi-square test was applied for nonparametric data. Results: Pain was significantly reduced in all the treatment groups postoperatively. Ibuprofen showed significant pain reduction at 4 h and 8 h period. The combination of low-level laser and ibuprofen showed the best results in terms of postoperative pain reduction. Conclusion: This study proved that low-level laser therapy can be an effective alternative for conventional use of nonsteroidal anti-inflammatory drugs in controlling postendodontic pain thereby eliminating the adverse effects of such drugs on the patients.
ABSTRACT
Background: Various environmental, socio-economic and geographical factors influence the pattern of dermatoses in an area. Observations made at tertiary dermatology centres may not reflect the actual pattern of dermatoses at the community level. Aims: To evaluate the pattern of dermatoses at community level and compare it with that at a tertiary centre. Methods: Cases were registered through community visits in block Hazratbal in Kashmir valley, once a week over a calendar year. The pattern of dermatoses observed was compared with that seen at the tertiary centre over the same period. Results: A total of 1065 community cases, with 1105 dermatoses, were compared with 4358 patients with 4466 dermatoses seen at the tertiary centre. Non-infectious dermatoses in each group were more common than infectious dermatoses (34.08% infectious dermatoses versus 65.97% non-infectious in community cases and 29.42% infectious dermatoses versus 70.58% non-infectious in hospital patients). Infectious cases were seen significantly more in the community (34.08%) than at the tertiary centre (29.42%). Among the infectious diseases, fungal infection was the most common and in the non-infectious group, pigmentary disorders were the most common, followed by acne and eczema. Conclusion : Infectious dermatoses were found statistically significantly more in community cases as compared to hospital patients while the opposite was the case with non-infectious dermatoses. The study emphasizes the need for providing frequent dermatology services to the community at the primary healthcare level so that the burden of dermatoses, especially infectious, may be reduced. Also, wider studies should be conducted in different regions in order to assess the actual magnitude of dermatological illnesses in the community.
