RESUMEN

In the fi eld of forensics, the use of dentition for identifi cation has been well established. Th e dental analysis has been employed mainly for the positive personal identifi cation of the person. Th erefore, the purpose of this review is to show the possibility of using the dental characteristics, for example, caries and dental restorations for the general profi ling of the decedent. It was found that many signifi cant relationships existed between the dental characteristics and the sex, race, age, and socioeconomic status of the person identifi ed. Th e socioeconomic status is having the least number of correlations while the age and race were seen to have the most.

RESUMEN

Aim: The purpose of present study is to assess the attitude of general dental practioners towards use rotary instruments and hand instruments for root canal treatment. Material and Methods: It was a cross-sectional questionnaire study conducted in the private clinics in Lucknow city, Uttar Pradesh. A total of 400 clinics were visited and face to face interview schedule was conducted. Questionnaire consists of demographic details of dental professionals. Information regarding the years of experience, OPD details and number of root canal treatment done per week by dental professionals was obtained. Use of rotary and hand instruments by dental professionals was inquired. Years of experience with Rotary instruments, procedural problems with rotary instruments faced by dental professionals and reasons for not using the rotary instruments if any was also recorded. Results: 102 (33%) of the total study samples were using rotary instruments for root canal treatment and 100 (32%) using both rotary and hand instruments for root canal treatment. Dentists who are using rotary instruments are facing the procedural problem of file breakage {70 (36%)}. And those dental professionals using hand instruments are facing the problem of ledge formation {82(40%)}. Conclusions: The main procedural failure of the rotary instruments in root canal treatment, faced by dental professionals was file breakage and with hand instrument is ledge formation. Lack of expertise is the main reason which restricts dental professionals from using rotary instruments.

RESUMEN

Aim: The present study evaluated the antimicrobial efficacy of Chlorhexidine, Nisin and Linezolid and a control group (Normal saline ) against Enterococcus faecalis (EF). Methods: Human single rooted premolars with type I canal anatomy were instrumented with ProTaper using NaOCl as an irrigant. Supension of EF was inoculated into each root specimen and incubated. The medicaments were syringed into each root and incubated. After 24 hours, 8 samples per group (among the 4 groups) were retrieved. A hole was drilled on each root, and the dentinal shavings obtained were allowed to fall in brain-heart infusion (BHI) broth. Dilutions from the broth were plated and spread over blood agar. Colony-forming units (CFU) of EF was counted. The procedure was repeated after 72 hrs and 1 week. Results: In group Nisin, the mean CFU was 10.6250 at 24 hrs, 6.6250 at 72 hrs and 6.2500 after 1 week respectively (statistically significant). In group Chlorhexidine, mean CFU was found to be the lowest of 10.5000 at 24 hrs, with further gradual increase to 13.7500 at 72 hrs and further increase to 15.8750 by 1 week. Similarly, in group linezolid , the mean CFU was found to decrease from 49.0000 at 24 hrs to 29.8750 at 72hrs and then increase to 34.8750 in 1 week.
