Background: Implant success is affected by initial bone resorption at the implant surface. Continuous efforts have been made to reduce the peri-implant crestal bone loss. Limited information is available regarding the influence of low level laser therapy (LLLT) on interaction between the bone and implant surface. Purpose: The aim of this pilot study was to assess the effect of LLLT on peri-implant crestal bone levels. Materials and methods: Twenty implants were placed in 20 patients who were randomly assigned to two groups. Group I patients' received no adjunctive treatment and group II patients' were administered LLLT using 980 nm diode laser at 0.1 W output power following implant placement. The energy density of 4 J/cm 2 was delivered at six sites for a duration of 10 seconds per site. Crestal bone levels were evaluated primarily using digital intraoral periapical (IOPA) radiograph. The measurements were made immediately (T0) and 6 weeks (T1) post implant placement; and 6 months (T2) and 1 year (T3) post prosthetic loading time intervals and compared using repeated measures ANOVA test. Results: Crestal bone levels at baseline were statistically not significant between groups (P = .880). At T3 time interval, the mean change in crestal bone levels around all anatomical implant sites measured was 0.81 (SE 0.04) mm for irradiated group and 0.97 (SE 0.04) mm for nonirradiated group. Intergroup analysis revealed statistically significant (P = .020) less crestal bone loss in group that received LLLT. Conclusion: Under the conditions of this study, LLLT reduced the crestal bone resorption surrounding dental implants. Trial registration: The present clinical trial was not registered.
The wellbeing and health of people are influenced by satisfaction about their job. The essence of job satisfaction is explained as mental gratification derived from one’s job. To know how the job satisfaction of an individual affects the other domains of an individual’s life like, psychological well-being and perceived stress in making an individual over-all healthy being. The study aims to investigate the Job satisfaction levels on psychological well-being and Perceived stress among government and private employees. Convenient sampling method was used in this study. In this study the sample consisted of 100 employees; 48 employees from the government sector and 52 employees from the private sector of the Delhi/ NCR region. For this study the behaviour tools used were job satisfaction scale, psychological well-being, and Perceived stress scale were taken for the study. These tools are used to measure government and private employee psycho social health issues. SPSS-18 software was used for data management. The results revealed significant negative correlation between Job satisfaction and Purpose in Life (r= -0.21) at p<0.05 level of significance. Perceived stress had a negative correlation between Autonomy (r= -.23) and Positive relation with others (r= -0.20) at p<0.05 level of significance. There was a significant difference between Government and Private sectors on Positive relations with others (p=0.003) at p<0.05 and Perceived stress (p=0.000) at p<0.05.
Persistent cerebrospinal fluid (CSF) rhinorrhea is an infrequent complication of frontal sinus trauma. It often require craniotomy for dural repair and obliteration of sinus with well vascularized pericranial flap. The multilayer vascularized techniques have gained popularity over the years owing to low rate of postoperative CSF leaks. The study retrospectively analyzed 25 frontal sinus trauma patients (20 males, 5 females) of mean age 32 AE 10.23 years with persistent CSF rhinorrhea from January 2011 to December 2018. All patients underwent frontal craniotomy and duraplasty was done with pericranial flap alone in 14 patients (Group I) and in combination with fascia lata graft in 11 patients (Group II). The clinical outcomes of single and double layer dural reconstruction techniques in management of CSF leak were analyzed. The size of defects ranged between 3 to 28 mm. Significant association was present between defect size and reconstruction technique with large defects underwent double layer repair. Two patients developed CSF leak following repair with pericranial flap alone. The rate of successful closure of CSF fistula was 100% with double layer reconstruction technique. However, statistically no significant association was noted between postoperative CSF leak and reconstruction technique. There was no evidence of meningitis, subdural hematoma, intracranial abscess, and mucocele formation in all patients during follow-up of 50.7 AE 23.6 months. To conclude, pericranial flap is a reliable reconstruction material for management of post traumatic frontal sinus CSF leaks. Dual flap technique that combine the use of fascia lata provides comprehensive solution of CSF fistula repair.
