A 5-year Follow-up of Projector System-Based Endodontic Treatment: Case Series.

Endodontic rehabilitation of grossly mutilated teeth is challenging. It requires reconstruction of the tooth under proper isolation before the commencement of the endodontic procedure. The study was designed to assess the 5-year performance of projector system-based endodontic restoration. Two patients diagnosed with pulpal necrosis and chronic periradicular periodontitis were provided with "Projector Endodontic Instrument Guidance System-" (PEIGS) based endodontic treatment. After access cavity preparation, the canals were cleaned, shaped, and further enlarged to receive the projectors with a snug fit after effective etching. The incremental composite buildup was performed in a standardized manner. On successful curing, the files and the projectors were retracted sequentially. This was followed by a conventional root canal therapy. A 5-year follow-up showed an intact tooth structure and patient compliance in both cases. Although a technique sensitive procedure, the PEIGS provides promising results.

An assessment of coronal leakage of permanent filling materials in endodontically treated teeth: An in vitro study.

INTRODUCTION: The present in vitro study was undertaken to evaluate and compare the sealing ability of hybrid composite, glass ionomer cement type II, silver amalgam and Ketac molar as permanent filling material in root canal treated teeth. METHODOLOGY: Hundred maxillary central incisors were selected for the study. After cleaning all the teeth, root canal treatment was carried out on all of them. The crown portion was cut-off at the cervical level. Three millimeter of coronal Gutta-percha was replaced by four different restorative materials. Then after thermocycling, samples were immersed in dye for 2 weeks. The amount of dye penetration was measured using stereomicroscope. Data were collected and analyzed statistically with ANOVA test and Student-Newman-Keuls test. RESULTS: Coronal leakage was seen in all groups. Composite hybrid showed least amount of microleakage as compared to the other three experimental groups, and Ketac molar showed more leakage compared to other experimental groups. CONCLUSION: This study showed that hybrid composites offer better sealing ability compared to other materials tested in this study.

Dental age estimation among female commercial sex workers in Goa.

INTRODUCTION: Age estimation is a sub-discipline of the forensic sciences and an important part of every identification process, especially when information relating to the deceased is unavailable. In India, close to 3.5 million women work as commercial sex workers (CSW) of which 1.2 million are under aged. AIM: To assess the dental and the skeletal age of rescued female CSWs with an intention of rehabilitation of the minors. METHODOLOGY: Dental age assessment of 32 rescued female CSWs with unknown age was done based on the radiographic analysis using regression equations derived in a Qualitative and Quantitative study by Dinkar A D. The skeletal age was assessed based on physical and radiological examination of the skeletal bones by Forensic experts. RESULT: It was observed that the estimated age of the CSWs ranged from 7 to 22 years out of which 22 cases (68.75%) were found to be below 18 years. When the dental and skeletal age was compared the maximum variation ranged between ± 12 months (1 year). Although the CSWs were found to be from different parts of India, maximum number of the cases (50%) was from Andhra Pradesh and one case (3.13%) was from Nepal. CONCLUSION: Dental age assessment using qualitative and quantitative method given by Dinkar A D can be thought of a reliable method for dental age assessment as it didn't show much variation when compared to the skeletal age of the 32 CSWs. In the present study 68.75% of the females were minor which shows that the number of minors being trapped in the trade of prostitution is increasing. Rescuing and rehabilitation of these minors is of paramount importance.

Cheiloscopy: revisited.

Identification plays a very important role in any crime investigation. Cheiloscopy helps in identifying the humans based on the lips' traces. The pattern of wrinkles on the lips has individual characteristics like fingerprints. A review of the literature reveals very little research done on lip prints so far. The present article reviews in detail the history, scope of cheiloscopy, and the use of lip prints in crime detection. It also highlights the current research carried out in the field of cheiloscopy. An effort has been made to help the researchers by reviewing in detail the various methods of classifying and analyzing the lip prints. It concludes by enlightening the readers with the fact that the possibilities to use the red part of lips to identify a human being are wider than it is commonly thought.

The effect of 0.5% sodium hypochlorite and 2% glutaraldehyde spray disenfectants on irreversible hydrocolloid impression material.

Infection control has assumed prime importance in dentistry. It is a prime concern in prosthodontics as well, where impressions materials are most commonly used. Impression materials can act as a medium for cross infection. To prevent cross infection many products are being developed. Among them 0.5% Sodium hypochlorite and 2% Glutaraldehyde are considered effective. This study was done to asses the efficacy of 0.5% Sodium hypochlorite and 2% Glutaraldehyde on irreversible hydrocolloid impression material. The result of the study indicated that they are effective against both Gram positive and Gram negative organisms and their use is recommended.
