Subcutaneous emphysema is a rare possible complication of dental procedures. The majority of the dental literature describes cases of localized areas of subcutaneous emphysema following various dental procedures, with a large number of these cases seen following intraoral surgical procedures. Classically, subcutaneous emphysema occurs within minutes to hours after conclusion of dental procedures and is commonly misdiagnosed as either an allergic reaction or acute post-operative swelling. This case report describes a four-year-old male who underwent dental rehabilitation for routine restorative dentistry without extractions under general anesthesia...

The role of a hospital consultant has changed extensively over the past decade as the National Health Service has progressed through a series of challenges including an ageing population and rising costs of clinical care. The traditional concept of a consultant has changed with different and increased expectations of the role as the pressures to deliver high quality patient care, education and advice continue to rise in a difficult financial climate. In addition, consultants in restorative dentistry are faced with the challenge of a poor general awareness of the scope of their speciality and their role...

Current dental restorations have short longevity, consequently there is a need for novel tissue engineering strategies that aim to regenerate the dentine-pulp complex. Dentine matrix contains a myriad of bioactive growth factors and extracellular matrix proteins associated with the recruitment, proliferation and differentiation of dental pulp progenitor cells. Here, we show that demineralised dentine matrix (DDM), from non-carious dentine, can be encapsulated into liposomes for delivery to dental tissue to promote regeneration...

Zirconia ceramic is a popular trend in esthetic and restorative dentistry. Computer-aided design/computer-aided manufacturing (CAD/CAM) systems have been well developed to fabricate zirconia frameworks and restorations with acceptable mechanical properties. Zirconia ceramics have excellent optical characteristics; however, achieving optimal esthetic outcomes with zirconia-based restorations is still challenging due to multiple effective factors on the final color. These factors are different layers of a zirconia-based restoration and its underlying structures including: dental substrate, cement, zirconia coping, veneering ceramic, and glaze...

The anatomical form of a tooth can undergo changes leading to loss of tooth form. The loss of tooth surface can be due to varying etiology. Dental caries, attrition, abrasion, erosion, involving any surface of the tooth can lead to loss of tooth structure. The rate of tooth destruction may proceed to such an extent that the esthetics, function and comfort may be lost. The role of a practioner lies in identification and screening of such case and motivate for oral rehabilitation that includes habit cessation...

Reattachment of the tooth fragment is an ultraconservative technique for managing coronal tooth fractures when the tooth fragment is available, and there is minimal violation of the biological width. The advances in adhesive dentistry have allowed dentists to use the patient's own fragment to restore the fractured tooth which provides fast and esthetically pleasing results. This article reports fragment reattachment technique and presents two clinical cases of complicated crown fracture.

Background: Many patients consider removal of caries to be a very unpleasant experience. Removal of caries with conventional drill is considered traumatic mainly due to fear and anxiety of children and their parents. Minimally invasive dentistry adopts a philosophy that integrates prevention, remineralization, and minimal intervention for the placement and replacement of restorations, thus reaching the treatment objective using the least invasive surgical approach, with the removal of the minimal amount of healthy tissues...

INTRODUCTION: Composite materials used in dentistry indicate adverse biological effects in laboratory conditions. One reason for this activity is incomplete conversion of their polymer matrix, favoring chemical instability and release of biologically harmful components to the external environment. AIM: The aim of the study was to assess the degree of conversion of restorative materials commonly available on the European market and to examine the cytotoxic effects of their eluates in vitro...

The most common discrepancy concerning tooth size is the presence of peg-shaped lateral incisors, which can cause teeth with reduced size, anterior diastema, and consequently an unpleasant smile. The development of the adhesive dentistry and ceramic veneers allowed all ceramic-bonded restorations to become an esthetic and functional approach to reestablish the smile harmony. The purpose of this clinical report is to describe a conservative treatment approach to recover an esthetic disharmony caused by bilateral peg-shaped lateral incisors...

Regeneration of pulp and dentin could be important in operative dentistry as a method to save teeth. Currently cell population from dental pulp of deciduous and permanent teeth of humans and laboratory animals are isolated and characterized. The paper presents a study on pulp regeneration using autologous mesenchymal stromal cells from pulp of molars in combination with fibrin clot, transplanted in pulp chamber of miniature pigs after pulp removal. The results proved that transplantation of autologous multipotent stromal cells of dental pulp in combination with autologous platelet-rich plasma in pulp chamber of miniature pigs after pulp removal leads to pulp restoration and reparative dentinogenesis with dentinal bridge formation on the 30th day...

REVIEW
Madhuri Bandi, Sreekanth Kumar Mallineni, Sivakumar Nuvvula
Ferric sulfate (FS) has been commonly used as a local hemostatic agent for more than three decades in dentistry. Even though the hemostatic mechanism of FS is questioned, it seems that agglutination of blood proteins occurs due to the reaction of blood with ferric and sulfate ions in acidic pH. FS has gained widespread importance as a pulpotomy medicament in contemporary dentistry; nevertheless, it has several applications in different fields of dentistry which was paid little attention. Hence, the purpose of this paper is to review the various applications of FS in dentistry, along with restorative dentistry and endodontics...

Dental disease annually affects billions of patients, and while regenerative dentistry aims to heal dental tissue after injury, existing polymeric restorative materials, or fillings, do not directly participate in the healing process in a bioinstructive manner. There is a need for restorative materials that can support native functions of dental pulp stem cells (DPSCs), which are capable of regenerating dentin. A polymer microarray formed from commercially available monomers to rapidly identify materials that support DPSC adhesion is used...

Most recent advances in tissue engineering in the fields of oral surgery and dentistry have aimed to restore hard and soft tissues. Further improvement of these therapies may involve more biological approaches and the use of dental tissue stem cells in combination with inorganic/organic scaffolds. In this study, we analyzed the osteoconductivity of two different inorganic scaffolds based on poly (lactic-co-glycolic) acid alone (PLGA-Fisiograft) or in combination with hydroxyapatite (PLGA/HA-Alos) in comparison with an organic material based on equine collagen (PARASORB Sombrero) both in vitro and in vivo...

Today, a substantial part of the dental crown production uses computer-aided design and computer-aided manufacturing (CAD/CAM) technology. A recent step in restorative dentistry is the replacement of natural tooth structure with pre-polymerized and machined resin-based methacrylic polymers. Recently, a new CAD/CAM composite was launched for the crown indication in the load-bearing area, but the clinical reality forced the manufacturer to withdraw this specific indication. In parallel, a randomized clinical trial of CAD/CAM composite crowns luted on zirconia implant abutments revealed a high incidence of failure within the first year of service...
