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...


Alterations in odontogenesis and tooth eruption resulting from exposure to hexavalent chromium in suckling animals.

Heavy metals including Cr VI are present in inadequately treated effluents that contaminate drinking water. Hence, Cr VI exposure can affect children through intake of breast milk from an exposed mother or bottle feeding formula prepared with contaminated water. To date, there are no reports on the effects of Cr VI exposure on tooth formation processes concomitant to tooth eruption.

Biological Effects of Anti-RANKL Antibody and Zoledronic Acid on Growth and Tooth Eruption in Growing Mice.

The anti-bone resorptive drugs denosumab, an anti-human-RANKL antibody, and zoledronic acid (ZOL), a nitrogen-containing bisphosphonate, have recently been applied for treatment of pediatric patients with bone diseases, though details regarding their effects in growing children have yet to be fully elucidated. In the present study, we administered these anti-resorptive drugs to mice from the age of 1 week and continued once-weekly injections for a total of 7 times. Mice that received the anti-RANKL antibody...


Development of the mandibular curve of spee and maxillary compensating curve: A finite element model.

The curved planes of the human dentition seen in the sagittal view, the mandibular curve of Spee and the maxillary compensating curve, have clinical importance to modern dentistry and potential relevance to the craniofacial evolution of hominins. However, the mechanism providing the formation of these curved planes is poorly understood. To explore this further, we use a simplified finite element model, consisting of maxillary and mandibular "blocks", developed to simulate tooth eruption, and forces opposing...

Distal Migration and Ectopic Eruption of the Mandibular First Premolar: A Case Report.

Migration describes the movement of an unerupted tooth within the bone when normal eruption is prevented and the tooth leaves its normal site of development. This report describes a case of distal migration and ectopic eruption of the mandibular first premolar in an 8.5-year-old boy. Following early extraction of the primary second molar, the first premolar migrated distally through the extraction site of the primary second molar and erupted into occlusion just mesial of the permanent first molar.

Eruption disturbance caused by an odontoma that was partially attached to the crown of the adjacent maxillary first molar, and step lesion excavation for the tooth preservation: A case report.

Despite the partial attachment of a complex odontoma to an impacted tooth, it is possible to guide the tooth to erupt normally and preserve it by step lesion excavation and the prevention of infection.

Can We Predict Bleomycin Toxicity with PET-CT?

Bleomycin is an antitumor antibiotic used successfully to treat a variety of malignancies, predominantly germ cell tumors and Hodgkin's lymphoma (HL). The major limitation of bleomycin therapy is the potential for life-threatening interstitial pulmonary fibrosis. Early identification of asymptomatic patients who may develop toxicity is important. We aimed to evaluate fluorodeoxyglucose positron-emission tomography (FDG-PET/CT) findings to predict bleomycin toxicity (BT) early after chemotherapy with doxorub...

Electrosclerotherapy as a Novel Treatment Option for Hypertrophic Capillary Malformations: A Randomized Controlled Pilot Trial.

Bleomycin sclerotherapy is ineffective for treating capillary malformations (CMs) because bleomycin cannot adequately be injected into the small-diameter capillary lumina. Electrosclerotherapy (EST) might be a new treatment modality for CMs, as it combines bleomycin sclerotherapy and "electroporation"-an electric field applied to the tissue. Electroporation disrupts the transmembrane potential, facilitating bleomycin transportation across the vessel wall, hypothetically leading to targeted drug delivery and...

A comparative study of intralesional injection of Candida Albicans Antigen, Bleomycin and 5- fluorouracil for treatment of plane warts.

Several therapeutic modalities for treatment of verruca plana (VP) are available, but none has achieved complete cure in all cases with associated risk of side effects. To evaluate efficacy and safety of intralesional injection of () antigen, bleomycin and 5- fluorouracil (5-FU) in treatment of VP. 60 patients with VP were randomly divided into 3 equal groups who were treated using antigen, bleomycin or 5- FU injections every 2 weeks till complete clearance of the lesions or for a maximum of 4 sessions ...

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, ...

Biomechanical stress regulates mammalian tooth replacement via the integrin β1-RUNX2-Wnt pathway.

Renewal of integumentary organs occurs cyclically throughout an organism's lifetime, but the mechanism that initiates each cycle remains largely unknown. In a miniature pig model of tooth development that resembles tooth development in humans, the permanent tooth did not begin transitioning from the resting to the initiation stage until the deciduous tooth began to erupt. This eruption released the accumulated mechanical stress inside the mandible. Mechanical stress prevented permanent tooth development by ...

Metformin protects from bleomycin-induced bactericide via enhanced generation of hydrogen peroxide.

Bleomycin is a glycopeptide antibiotic that is widely employed in the therapy of a range of lymphomas and germ cell tumours. But the therapeutic efficacy of bleomycin is limited by development of lung fibrosis. The cytotoxicity of bleomycin is mostly ascribed to mitochondrial DNA (mtDNA) damage, while a protective effect of metformin against bleomycin-induced lung fibrosis results from the inhibition of mitochondrial complex I. Since mitochondria and bacteria have certain similarities in structure and funct...

A first case of fixed drug eruption due to Tamsulosin.

Fixed Drug Eruption (FDE) is a drug reaction involving the skin and less commonly the mucosal membranes. Tamsulosin is an alpha-1 adrenergic receptor blocker used to treat benign prostatic hyperplasia. Dizziness and headache are among its most common side effects (Singapore Med J, 2018;59:336). Although cutaneous drug eruption has been reported with other alpha-1 adrenergic receptor blockers.

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.

Oral Manifestations of Magnesium and Vitamin D Inadequacy.

Adequate nutrition is essential for maintaining good oral health. Minerals such as magnesium, calcium, and phosphorus found in the diet constitute the main structural components of the tooth. Their inadequacy leads to absorption impairment, increased bleeding tendency, bone resorption, looseness, and premature tooth loss. Inadequacy of those essential minerals is associated with delayed tooth eruption and with enamel or dentin hypoplasia. Taking calcium without magnesium results in soft dental enamel, which...

Does Potassium Iodide application following Silver Diamine Fluoride reduce staining of tooth? A Systematic Review.

To assess if using potassium iodide (KI) immediately after application of Silver Diamine Fluoride (SDF) significantly reduces the staining of tooth structure.

Ganoderic Acid A Inhibits Bleomycin-Induced Lung Fibrosis in Mice.

To study the protective effects of ganoderic acid A (GAA) on bleomycin (BLM)-induced pulmonary fibrosis.

Bleomycin in Hodgkin's Lymphoma - A Boon or a Bane? - A Retrospective Study of Bleomycin Pulmonary Toxicity in Hodgkin's Lymphoma.

Hodgkin's lymphoma (HL) is one of the most curable malignancies with cure rates of above 85% across all stages. Bleomycin containing regimen is routinely employed in the treatment of HL. Pulmonary toxicity due to this drug is the most feared side effect in these regimens where the mortality rate is approximately 2%-3%. We have conducted this study to assess the genetic susceptibility among the Indian HL patients to bleomycin pulmonary toxicity (BPT).

Enhanced in vitro efficacy for inhibiting hypertrophic scar by bleomycin-loaded dissolving hyaluronic acid microneedles.

Hypertrophic scarring is a widespread skin disorder that affects a patient's confidence and quality of life. Intralesional injection of bleomycin is one of the most commonly employed treatments for hypertrophic scars, which, however, always brings pain and requires long-term treatment. To overcome these limitations, new methods for bleomycin delivery enabling painlessness, self-administration, the fast onset of action, and good bioavailability are urgently needed. In this study, we developed bleomycin-loade...

Effects of different light sources on tooth shade selection.

Differences in lighting conditions can make matching the shade of a single porcelain tooth to the natural adjacent teeth very challenging.

Tooth wear in Swedish adults - a cross-sectional study.

Tooth wear, has been recognized as a growing oral health problem in children and adolescents, with erosion often cited as the main cause of the tooth wear. Most studies on tooth wear have been conducted on children and adolescents, and only few studies focus on adults. Our aim was to study the prevalence of different types of tooth wear in an adult population and investigate related factors to tooth wear.

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.

To extract or not to extract? Management of infraoccluded second primary molars without successors.

Infraocclusion is a term used to describe a tooth which has stopped its relative occlusal growth into the arch after the period of active eruption; as a result, the tooth becomes depressed below the occlusal plane. Although many aetiological mechanisms have been proposed, ankylosis is considered the primary cause of infraocclusion. Complex cases benefit from multidisciplinary management. This paper concentrates on the diagnosis and management of infraoccluded second primary molars, without permanent success...

Long-term outcomes with intensive induction chemotherapy (carboplatin, bleomycin, vincristine and cisplatin/bleomycin, etoposide and cisplatin) and standard bleomycin, etoposide and cisplatin in poor prognosis germ cell tumours: A randomised phase II trial (ISRCTN53643604).

Up to 50% of men with poor prognosis, non-seminoma germ cell tumours (GCTs) die with standard BEP (bleomycin, etoposide and cisplatin) chemotherapy. An intensive regimen, CBOP/BEP (carboplatin, bleomycin, vincristine and cisplatin/BEP), met response targets in a randomised, phase II trial (74% complete response or partial response marker negative, 90% confidence interval (CI) 61%-85%).

Notch Coordinates Periodontal Ligament Maturation through Regulating Lamin A.

Tooth eruption is a continuous biological process with dynamic changes at cellular and tissue levels, particularly within the periodontal ligament (PDL). Occlusion completion is a significant physiological landmark of dentition establishment. However, the importance of the involvement of molecular networks engaging in occlusion establishment on the final PDL maturation is still largely unknown. In this study, using rat and mouse molar teeth and a human PDL cell line for RNAseq and proteomic analysis, we sys...
