Juvenile obsessive compulsive disorder in a paediatric dentistry set-up.

Obsessive-compulsive disorder (OCD) is an anxiety disorder comprising uncontrollable thought processes and repetitive, ritualised behaviours that one feels compelled to perform. If an individual has OCD, he/she probably realises that his/her obsessive thoughts and compulsive behaviours are irrational but would still feel unable to resist them. Since a pedodontist's association with the child patient and parents is established at quite an early age, they should make good use of the opportunity to diagnose psychological disorders in child patients as well as adolescents.

SHED - Basic Structure for Stem Cell Research.

The discovery that stem cells from dental pulp are capable of differentiating into endothelial cells raised the exciting possibility that these cells can be a single source of odontoblasts and vascular networks in dental tissue engineering. These so-called mesenchymal stem cell populations have been identified from human exfoliated deciduous teeth because of their ability to generate clonogenic adherent colonies when grown and expanded. In addition to these stem cells, other population of stem cells can be from adult human dental pulp and periodontal ligament.

Access to abutment screw in cement retained restorations: a clinical tip.

Abutment screw loosening has been reported to be the most common prosthetic complications occurring in screw retained as well as cement retained implant restorations. Different methods to treat this issue have been reported in the literature so far; however these have their own short-comings. Retrievability of an implant restoration intact becomes a clinical challenge when the restoration is cement retained especially with an angulated abutment.

Rehabilitation of amputed thumb with a silicone prosthesis.

Creating prosthesis, having realistic skin surface and seamless visual integration with the surrounding tissues, requires both artistic and technical skill. Anatomical design, thin margins, lifelike fingernails and realistic color/contours are essential for patient satisfaction. Prosthesis is especially useful in case of lost body parts, as reconstructive surgery cannot fully restore aesthetics.

Endodontic-periodontal microsurgery for combined endodontic-periodontal lesions: An overview.

Endodontic and periodontal microsurgery has surpassed the success rates for traditional endodontic and periodontal surgical procedures. Excellent healing results are being attributed to both the techniques, when employed, for isolated endodontic or periodontal defects. Combined endodontic-periodontal lesions have been referred to as a true challenge, requiring not only endodontic microsurgical management but also concurrent bone grafting and membrane barriers techniques.

Titanium allergy: a literature review.

Titanium has gained immense popularity and has successfully established itself as the material of choice for dental implants. In both medical and dental fields, titanium and its alloys have demonstrated success as biomedical devices. Owing to its high resistance to corrosion in a physiological environment and the excellent biocompatibility that gives it a passive, stable oxide film, titanium is considered the material of choice for intraosseous use.
