To evaluate dimensional stability when various combinations of dental plaster and dental stone are used as an investment material.

Dental plaster is routinely used as an investing material to acrylize dentures with some acceptable linear dimensional changes in the finished acrylic denture. This study aimed to evaluate which combination of dental plaster and dental stone, when used as an investment, will produce fewer linear dimensional changes in acrylic dentures.

An aluminum block is prepared with sharp margins. The block is invested with various combinations of dental plaster and dental stone. The linear dimensional changes are measured using a digital caliper.

The results obtained were subjected to statistical analysis using analysis of variance test.

Investing with 100% dental stone and a combination of 70% dental stone and 30% dental plaster showed fewer dimensional changes.

A combination containing higher percentage of dental stone may be used for investing to produce a finished denture with fewer linear dimensional changes.

Treatment with dental implants has become increasingly important in the range of prosthodontic treatment. Significant improvements in oral rehabilitation particularly in edentulous individuals have been seen. In Adhiparasakthi Dental College, Melmaruvathur, a survey was made to evaluate awareness among patients for dental implants, their level of knowledge, and attitude toward replacement of missing teeth by dental implants.

A survey of 480 people was conducted through a printed questionnaire and completed by willing respondents. The questionnaires were prepared in English and Tamil language to enable better understanding and completion.

Of the 510 people surveyed, 480 responses were retrieved, of which 331 were aware of dental implant treatment in Melmaruvathur, Tamil Nadu. Among them, 304 respondents were aware that implants could be used for replacement of missing teeth. Most of the respondents stated that dental implants were placed in the jawbone, followed by gums. Only 41% respondents assumed that implants last for a lifetime and only 35% of respondents believe that poor oral hygiene was the most common cause of implant failure.

More dental education programs are needed to improve understanding of the importance of restoration of missing teeth. General implant awareness levels are satisfactory. However, increased awareness of patients for restoration of missing tooth with dental implants is necessary. Dental education programs with special emphasis on advantages, treatment, maintenance, and postoperative care of dental implant therapy are needed. More than two-thirds of the surveyed population is interested in knowing about and being treated with dental implants.

To present a novel approach for nonsurgical management of large periapical lesion with open apex by using White Portland Cement to create an apical plug leads to substantial periapical healing.

Radiographic examination in this case indicated previous root canal treated, immature tooth with a wide-open apex and a periapical radiolucency. After cleaning and shaping Triple antibiotic paste was placed for 3 weeks. Hydroxyapatite was mixed with sterile saline & placed beyond the canal apex until with the aim of creating a periapical barrier. WPC powder was then mixed with sterile water, carried inside the canal to create apical plug (4mm) and obturation. The remainder of the canal was filled with thermoplastic gutta-percha. This was followed by post &core and PFM crown. Clinical follow-up of 2 years revealed absence of clinical symptoms and substantial periapical healing.
