OBJECTIVE Aim of the present study was to evaluate the cytotoxicity of Real Seal 1 compared to other commercially available endodontic filling materials: Real Seal (SybronEndo, Orange, CA, USA) and Thermafil (Tulsa Dental, Tulsa, OK, USA). MATERIAL AND METHODS Periodontal ligament cells from healthy patients were cultured. The eluate of Real Seal 1(TM) (RS1), Real Seal (RS) and Thermafil (TF)...

This paper describes the program structure and strategies being used by the Massachusetts Department of Public Health to promote the utilization of sealants. The program design includes four components: clinical demonstration, consumer education, professional education, and reimbursement. Eighteen Massachusetts neighborhood health centers and six local health departments are participating in th...

Sample wafers of compounded dental gutta-percha and uncompounded dental-grade gutta-percha were compression tested to 20,000 pounds in uniaxial and triaxial systerns. Unrestrained flow in the uniaxial series prevented development of stress levels sufficient to produce molecular compression. Negligible molecular compression did occur in the triaxial series but only above a stress level of approx...

Adv Dent & Oral Health 4(1) : ADOH.MS.ID.555628 (2017) Introduction Traumatic dental injuries are common among pediatric dental patients. Approximately 20-30% of children have suffered dental injuries by the age of 12 [1]. Intrusion injuries, though considered rare in the permanent dentition [2], are seen more frequently in the pediatric population [3]. Intrusion is defined as a displacement of...

The cleft palate is associated with feeding difficulties, dysfunction of eustachian tube, infection and effusion of middle ear, hearing loss, disorders of speech, dental and orthodontic problems. Feeding plate is a prosthetic aid that is designed to seal the cleft and restore the separation between oral and nasal cavities. This clinical report describes fabrication of feeding plate for neonate ...

AIM At present, two different clinical procedures to ensure the adherence of indirect tooth restorations to the dental tissues are available: a traditional method based on a delayed dentin sealing (DDS) and an innovative approach that contemplates an immediate dentin sealing (IDS). In this study the authors highlight the advantages of the latter method (IDS), decribing the operating phases of t...

The success of dental implant treatment depends on the healing of both hard and soft tissues. While osseointegration provides initial success, the biological seal of the peri-implant soft tissue is crucial for maintaining the long term success of implants. Most studies of the biological seal of peri-implant tissues are based on animal or monolayer cell culture models. To understand the mechanis...

OBJECTIVE Dental implants anchor in bone through a tight fit and osseo-integratable properties of the implant surfaces, while a protective soft tissue seal around the implants neck is needed to prevent bacterial destruction of the bone-implant interface. This tissue seal needs to form in the unsterile, oral environment. We aim to identify surface properties of dental implant materials (titanium...
