Abstract Supernumerary teeth are described as the teeth formed in excess of the number found in a

normal dentition. Multiple supernumerary teeth without any associated condition or

syndromes are relatively uncommon. In this case report, a 22-year male showed the presence of multiple supernumerary teeth. The medical history was noncontributory, and

an extra oral examination did not reveal any abnormality. This case was unique because

of the presence of good intercuspal relation even in presence of crowding and impaction.

Abstract Behind all complexities in the world stand simple solutions. In the present era of fixed

prosthetic dentistry cast partial dentures are still being used owing to the anatomical and

biomechanical constraints in the oral cavity. The difficulties encountered by patients with cast partial denture are an age old saga. The common problems are unaesthetic

appearance of the clasp, rigidity of denture base resin, unavoidable tooth preparation, weight of the prosthesis, the lever effect causing abusive forces on the abutments, etc.

Thermoplastic resins with inherent flexibility are the panacea for this problem.

Therapeutic use of these resins has drastically sprung up in the last decade. Unlike the conventional technique of making dentures, flexible dentures are made by injection

molding technique. Various thermoplastic resins are available in the market today. This article presents a review of thermoplastic resins with their properties and aims at the

potential areas of application and advances in future.

Comparative Evaluation of Shear Bond Strength of

Three Different Generations of Adhesive to

Dentin: An In Vitro Study

Hospital, AMU, Aligarh, India

Abstract The clinical use of resin composites has expanded considerably over the past few years

due to increased esthetic demands by patients, new improved formulations, and

simplification of bonding procedures. Novel resin composites benefits from improved filler technology and modifications of the organic matrix for a greater degree of

polymerization .Improved marginal sealing around composites has reduced the frequency of unfavorable postoperative responses. The sealing ability of a composite restoration is

directly related to the effectiveness of the adhesive system used, as the lack of bonding

and inadequate marginal sealing may lead to restoration failure.

Abstract In clinical dental practice, patients often present with pain in the oral cavity. While some

oral pain may be generalized in nature, the clinician has to consider other factors that involve pain and discomfort. Many symptomatic teeth do not need endodontic treatment –

on the contrary, they have undiagnosed occlusal problems, caries, fractures or referred

pain. For the teeth needing endodontic treatment, this paper provides several modes of diagnostic methodology. The etiology of endodontic pain from the infected pulp consists

largely of the following clinical factors: 1) Pulpal – Cariogenic microorganisms in the oral cavity exposing dental tubules and

direct infection of the pulp chamber and root canals

2) Periodontium/Alveolar bone – Chronic periodontal disease exposing the apical foramen and/or accessory (lateral) root canals.

3) Alveolar bone – Cyst or granuloma formation at the apex reflecting chronicity of

infection in the development and progression of degenerative changes that constitute periodontal disease and subsequent bone loss.

Defective restorations, interproximal caries, and open proximal contacts acting as food

traps create a locus for significant pathology. As a result of toxins released from the

action of bacterial colonies on impacted food, plaque, and calculus, there is subsequently substantial inflammation, infection, and pain. Preventing food impaction by maintaining

or restoring contacts between the proximal surfaces of adjoining teeth and repairing defective restorations are primary concerns in preventing the morbidity of oral infections.

The development of endodontic infections and their sequelae produce active loci of

disease that ultimately cause pain and negative involvement of the periodontium, pulpal tissues, and alveolar bone. Socioeconomic factors like lack of financial resources, lack of

access to dental offices/clinics, lack of transportation, and cultural factors may limit the

patient to receiving only pain-motivated dental care. In the long run, infection, inflammation, and tooth loss negatively impact the overall health of the patient.

Abstract Diagnosis and treatment of dental-related symptomology should be conducted with the

understanding that dental conditions may influence the course and conduct of medical

therapy. Many people with severe orofacial pain and/or swelling come to the local

hospital ER for treatment of dental problems. The economics of health care in the United States is burdened by high-cost hospital ER dental visits largely by poverty level patients

having few treatment options and limited opportunities for follow-up care. The aims and

objectives of this article are to address utilization and policy concerns of the increasing use of the hospital ER for preventive and emergency dental visits. The article identifies

what constitutes an “acute dental emergency” and promotes alternatives for dental

treatment. The demography of patients seeking dental treatment at the hospital ER is described along with the growing concerns about the effects of this practice on the health

care system. The authors provide recommendations for positive change in the existing environment of the provision of dental services by the hospital ER. The policy of

governments at all levels, in the best interest of the public health, should address and

provide for emergency dental care. The Federal Government should provide alternatives to the hospital ER dental visit by poverty-level patients with low cost insurance plans that

mirror the medical coverage for everyone taken by “Obama care”.
