Decellularized human periodontal ligament for periodontium regeneration.

Regenerating the periodontal ligament (PDL) is a crucial factor for periodontal tissue regeneration in the presence of traumatized and periodontally damaged teeth. Various methods have been applied for periodontal regeneration, including tissue substitutes, bioactive materials, and synthetic scaffolds. However, all of these treatments have had limited success in structural and functional periodontal tissue regeneration. To achieve the goal of complete periodontal regeneration, many studies have evaluated th...


Tooth and consequences: Heterodonty and dental replacement in piranhas and pacus (Serrasalmidae).

Tooth replacement in piranhas is unusual: all teeth on one side of the head are lost as a unit, then replaced simultaneously. We used histology and microCT to examine tooth-replacement modes across carnivorous piranhas and their herbivorous pacu cousins (Serrasalmidae) and then mapped replacement patterns onto a molecular phylogeny. Pacu teeth develop and are replaced in a manner like piranhas. For serrasalmids, unilateral tooth replacement is not an "all or nothing" phenomenon; we demonstrate that both sid...

Extreme root resorption in orthodontic practice: teeth do not have to be replaced with implants.

The replacement of natural teeth that have extreme external apical root resorption, induced by orthodontic treatment, with osseointegrated implants is not justifiable biologically or clinically. These teeth should be preserved and keep their normal functions, as there is no greater mobility, pain or color change. They may undergo usual procedures, such as bleaching, restorations with veneers and other esthetic procedures that may be necessary along life. The pulp of these teeth is normal. If mobility of a t...


Getting out of an egg: merging of tooth germs to create an egg tooth in the snake.

The egg tooth is a vital structure allowing hatchlings to escape from the egg. In squamates (snakes and lizards), the egg tooth is a real tooth that develops within the oral cavity at the top of the upper jaw. Most squamates have a single large midline egg tooth at hatching, but a few families, such as Gekkonidae, have two egg teeth. In snakes the egg tooth is significantly larger than the rest of the dentition and is one of the first teeth to develop.

Influential factors related to the long-term effect of periodontal-orthodontic treatment in patients with aggressive periodontitis and malocclusion.

To investigate the influential factors related to the long-term effect of periodontal-orthodontic treatment in patients with aggressive periodontitis (AgP). A retrospective analysis was conducted in 25 AgP patients, who have received periodontal-orthodontic treatment in Peking University School and Hospital of Stomatology. Changes in the ratio of the residual alveolar bone height (RBH) was measured at three time points: baseline (T0), post orthodontic treatment (T1), and the last re-visit 3 years after ort...

Effects of bleomycin on tooth eruption: a novel potential application.

There are many kinds of potentially undesirable teeth. At present, surgical extraction is the most efficient way to eliminate these teeth, but it's very complex and invasive. In this study, we investigated the effects of bleomycin (BLM) on dental follicle and tooth eruption as a potential conservative therapy for undesirable teeth. Our data showed that local injection of 0.2 U/kg BLM had no significant effects on tooth eruption compared to the control group in Wistar rats. With higher dose of BLM (0.5or 2 U...

Stem cells in the periodontal ligament differentiated into osteogenic, fibrogenic and cementogenic lineages for the regeneration of the periodontal complex.

Human periodontal ligament stem cells (hPDLSCs) are promising for periodontal regeneration. However, to date, there has been no report of hPDLSC differentiation into the fibrogenic lineage. There has been no report demonstrating hPDLSC differentiation into all three (osteogenic, fibrogenic and cementogenic fibrogenic) lineages in the same report. The objectives of this study were to harvest hPDLSCs from the periodontal ligaments (PDL) of the extracted human teeth, and use the same vial of hPDLSCs to differe...

We report a case of generalized chronic periodontitis requiring periodontal treatment including regenerative therapy. The patient was a 57-year-old who man presented with the chief complaint of gingival swelling and mobile teeth in the right maxillary molar region. An initial examination revealed 55.3% of sites with a probing depth of ≥4 mm and 24.0% with bleeding on probing. Radiographic examination revealed vertical bone resorption in teeth #16, 17, 25, 26, 37, and 45; horizontal resorption was also not...

Use of Buccal Fat Pad in the Treatment of Peri-Implant Mucosal Defect: A Case Report.

The present study describes a clinical case in which the buccal fat pad (BFP) was used to improve the contour of the peri-implant mucosa. To our knowledge, this is the first case report of such application in the literature. A 58-year-old woman presented with teeth #2 and #3 missing and an indication for extraction of tooth #4. After clinical examination and CBCT analysis, immediate implants were placed in the region of the extracted tooth and of tooth #2 for prosthetic rehabilitation using a three-unit fix...

An enzyme-responsive membrane for antibiotic drug release and local periodontal treatment.

Periodontitis is a chronic, destructive inflammatory disease that injures tooth- supporting tissues, eventually leading to tooth loss. Complete eradication of periodontal pathogenic microorganisms is fundamental to allow periodontal healing and commonly precedes periodontal tissue regeneration. To address this challenge, we report a strategy for developing an enzyme-mediated periodontal membrane for targeted antibiotic delivery into infectious periodontal pockets; the unique components of the membrane will ...

Vitamin Cand eggshell membrane facilitate orthodontic tooth movement and induce histological changes in the periodontal tissue.

Collagen remodeling of the periodontal tissue is an important mechanism that involves several biologically active substances to accelerate orthodontic tooth movement. It is known that Vitamin C (VC) enhances collagen production and induces tooth movement. Moreover, the eggshell membrane (ESM) is an integral component of various formulations used to promote wound healing. The purpose of our study was to determine the effects of combined treatment with VC and ESM on periodontal tissues during tooth movement.

The extraction of first, second or third permanent molar teeth and its effect on the dentofacial complex.

The extraction of permanent molar teeth was first introduced in 1976 as a substitution for premolar extraction in cases with mild crowding. Since then, a number of studies have investigated the effect of permanent molar extraction on dentofacial harmony. Undertaking the procedure of molar extraction is most commonly recommended in response to factors such as: gross caries, large restorations and root-filled teeth, along with its application in the management of anterior open bite and reduction of crowding i...

Tooth Regeneration: Insights from Tooth Development and Spatial-Temporal Control of Bioactive Drug Release.

Tooth defect and tooth loss are common clinical diseases in stomatology. Compared with the traditional oral restoration treatment, tooth regeneration has unique advantages and is currently the focus of oral biomedical research. It is known that dozens of cytokines/growth factors and other bioactive factors are expressed in a spatial-temporal pattern during tooth development. On the other hand, the technology for spatial-temporal control of drug release has been intensively studied and well developed recentl...

Regrowing a tooth: in vitro and in vivo approaches.

Biologically oriented regenerative dentistry in an attempt to regrow a functional tooth by harnessing the natural healing capabilities of dental tissues has become a recent trend challenging the current dental practice on repairing the damaged or missing tooth. In this review, we outline the conceptual development on the in situ revitalization of the tooth replacement capability lost during evolution, the updated progress in stem-cell-based in vivo repair of the damaged tooth, and the recent endeavors for i...

Is selective protein adsorption on biomaterials a viable option to promote periodontal regeneration?

Periodontitis is an inflammatory condition that can induce significant destruction of the periodontium, the set of specialized tissues that provide nourishment and support to the teeth. According to the guided tissue regeneration principles, the periodontium can be regenerated if the spatiotemporal control of wound healing is obtained, namely the tune control of cell response. After material implantation, protein adsorption at the interface is the first occurring biological event, which influences subsequen...

Unintentional removal of a developing permanent premolar during primary molar extraction: a 10-year case report.

A 14-year-old girl underwent extraction of an ankylosed primary left second molar as requested by her orthodontist. The developing mandibular left second premolar (tooth 20) was unintentionally removed during extraction of the primary molar. Immediate measures were taken to reimplant tooth 20. Recall appointments over the next 10 years included monitoring of tooth 20. The patient also was followed up closely by her orthodontist during this time. Tooth 20 was monitored for proper eruption, root development, ...

Evolution of high tooth replacement rates in theropod dinosaurs.

Tooth replacement rate is an important contributor to feeding ecology for polyphyodont animals. Dinosaurs exhibit a wide range of tooth replacement rates, mirroring their diverse craniofacial specializations, but little is known about broad-scale allometric or evolutionary patterns within the group. In the current broad but sparse dinosaurian sample, only three non-avian theropod tooth replacement rates have been estimated. We estimated tooth formation and replacement rates in three additional non-avian the...

A Rare Case of Nasolacrimal Duct Partial Obstruction After Extraction of an Impacted Maxillary Canine.

The main complications of tooth extraction include jaw fracture, maxillary sinus damage, adjacent teeth damage, nerve damage, root fracture, infection, bleeding, and swelling. Despite the theoretical possibility that tooth extraction could result in nasolacrimal duct obstruction, to the best of our knowledge, no cases have yet been reported. In the present study, we have described a case in which the nasolacrimal duct was partially obstructed after extraction of an impacted maxillary canine, causing paranas...

Management of immature necrotic permanent teeth with regenerative endodontic procedures - a review of literature.

Immature necrotic permanent tooth presents a distinctive challenge for the endodontist. Various treatment modalities have been employed to create hard tissue barrier at the apex, which includes non-vital pulp therapy with calcium hydroxide, apexification with mineral trioxide aggregate, pulp revascularisation and regeneration. Regenerative endodontics is a novel modality which involves physiological replacement of the damaged structures of tooth like dentin, root and cells of the pulp-dentin complex. Numero...

Dental Injuries and Management.

Traumatic dental injuries affect 1 to 3% of the population, and disproportionately affect children and adolescents. The management of these injuries incorporates the age of patients, as children between 6 and 13 years of age have a mixed dentition. This helps to preserve the vitality of teeth that may be salvaged after a traumatic event. The clinical examination of these cases involves a thorough examination of the maxilla and mandible for associated fractures and any lodged debris and dislodged teeth or to...
