BACKGROUND: Keratin has shown promising outcomes as a biomaterial due to its inherent bioactivity, biocompatibility and regenerative effects. The effect of keratin on repair and regeneration of dental tissues has never been studied before. Current therapies to treat pulp tissues involve its replacement with inert, synthetic materials that do not have a proper biological function, leading to failure and tooth loss. This study aimed to develop a biocompatible keratin hydrogel (KH) suitable for pulp therapies...

Atsushi Oishi
This case report describes the importance of continual examination for dental trauma and the efficacy of intentional replantation with retrograde root canal filling for a transverse root fracture in an immature incisor accompanied by subsequent periodontal-endodontic disease. In the treatment of traumatically fractured roots in immature incisors, continual examination is indispensable for the final diagnosis because roots in immature teeth are less calcified, resulting in less detailed radiological examinations...

BACKGROUND: Odontogenic infections, and especially endodontic infections, are polymicrobial, involving a combination of Gram-positive and Gram-negative facultative anaerobes and strictly anaerobic bacteria. Therefore, antibiotics can be used as an adjunct to endodontic treatment. However, most chronic and even acute endodontic infections can be successfully managed by disinfection of the root-canal system, which eliminates the source of infection, followed by abscess drainage or tooth extraction, without the need for antibiotics...

Martin Tungotyo
BACKGROUND: Ebiino, also known as false tooth extraction, is a traditional practice done mainly in the remote areas of African countries, including Uganda. It involves the extraction of tooth buds in babies with common childhood illnesses such as fever, cough, and diarrhea. It is thought that the tooth buds are responsible for the ailments seen in these infants. The practice is performed by traditional healers using unsterile instruments. The complications associated with this dangerous practice have been mentioned in the literature and include anemia and septicemia, among others...

The objective of this study was to quantitatively determine ridge contour changes after different alveolar ridge preservation techniques. An initial total of 40 patients provided a final total of 35 single-gap extraction sites. After tooth removal, the socket was subjected to one of four treatment modalities: placement of a deproteinized bovine bone mineral (DBBM; Endobon) covered with a soft tissue punch from the palate (Tx1); placement of DBBM without soft tissue punch (Tx2); placement of an adsorbable collagen membrane (Osseoguard) covering the DBBM (Tx3); and no additional treatment (control)...

Part 1 of this series introduced the partial extraction therapies as a group of techniques for ridge preservation at immediate implant placement and beneath pontic sites. The concept proposes a paradigm shift away from extract and augment toward partly retaining the tooth root to preserve the ridge and prevent buccopalatal collapse. The revolutionary socket-shield technique was introduced in 2010; however, there has been no follow-up literature to guide the clinician in terms of procedural steps. While root submergence is well established, the socket-shield and pontic shield are still in their clinical infancy and require long-term clinical data before they can be proposed as routine in everyday implant dentistry...

Treated dentin matrix (TDM) as a kind of scaffolding material has been proved odontogenic induction ability on dental-derived stem cells. Given the limited resources of dental stem cells, it is necessary to seek new seed cell which easily obtained. Jaw bone marrow mesenchymal stem cell (JBMMSC) as non-dental-derived stem cell relates to the development of teeth and jaws which suggest us JBMMSCs could act as a new seed cell for tooth tissue engineering. To assess the odontogenic and osteogenic potential of JBMMSCs, cells were induced by TDM extraction in vitro and combined with TDM in vivo...
