Comparison of Mineral Trioxide Aggregate and Calcium Hydroxide as pulpotomy agents in Primary Molars

Update Dental College Journal, 2014
Background: The greatest threats to developing teeth are dental caries and traumatic injury. If pulpal exposure occurs, then a pulpotomy procedure aims to preserve pulp vitality to allow for normal root development.

Pulpal sequelae after trauma to anterior teeth among adult Nigerian dental patients

BMC Oral Health, 2007
Background Epidemiological studies show that about 11.6% to 33.0% of all boys and about 3.6% to 19.3% of all girls suffer dental trauma of varying severity before the age of 12 years.

Decreased pH does not alter metamorphosis but compromises juvenile calcification of the tube worm Hydroides elegans [PDF]

Marine Biology, 2012
Using CO2 perturbation experiments, we examined the pre- and post-settlement growth responses of a dominant biofouling tubeworm (Hydroides elegans) to a range of pH. In three different experiments, embryos were reared to, or past, metamorphosis in seawater equilibrated to CO2 values of about 480 (control), 980, 1,480, and 2,300 μatm resulting in pH ...

Transmigrated Mandibular Canine and Impacted Maxillary Canines – A Distinctive Case Report

Journal of Indian Academy of Oral Medicine and Radiology
Migration of teeth is a well-known phenomenon, but dental transmigration, that is, pre-eruptive shifting of teeth across the midline, is a rare anomaly. Transmigration occurs mainly in impacted teeth and is almost seen primarily in canines.

Surgical Management of Calcific Metamorphosis of Pulp: A Case Report

BIRDEM Medical Journal, 2012
A case is reported which states calcific metamorphosis of pulp in a mandibular left lateral incisor and concomitant pulp necrosis of both central incisors for a single trauma. There was a large periapical lesion associated with the teeth. Conventional endodontic treatment was performed on teeth with pulp necrosis, but the canal with calcific ...

Guided endodontics for calcified teeth: A case of improved precision and treatment efficiency

Endodontology
Traumatic dental injuries, such as concussion and subluxation, can lead to significant pathological changes in the dental pulp, including calcific metamorphosis (CM) and inflammatory external root resorption (IERR).

Aesthetic management of complete calcific metamorphosis: a case report

International Journal of Research in Medical Sciences, 2018
Calcific metamorphosis teeth are a great challenge to the clinician. Its diagnosis and treatment procedures are of utmost importance in providing the best treatment. Understanding the mechanism behind the discoloration of teeth is the key to get the best treatment.

Atomic Layer Deposition Processes: Versatile Platforms for Engineering ZnO‐Chitosan Biointerfaces

Advanced Healthcare Materials, EarlyView.
Vapour phase metalation (VPM), multiplied pulsed vapour phase infiltration (MPI), and O2 plasma‑enhanced atomic layer deposition (PEALD) tailor Zn–chitosan (Zn‑CS) films. PEALD improves wettability and biocompatibility. MPI enhances semiconductor behavior. Antiseptic selectivity: VPM → E. coli; MPI → H. pylori.

Stage‐Specific H3K14 and H3K23 Succinylation Orchestrates Insect Metamorphosis and Oogenesis

Advanced Science, EarlyView.
Stage‐specific succinylation of histone H3 at lysine 14 and 23 differentially controls insect metamorphosis and oogenesis through distinct GPCR‐PKC signaling cascades, revealing an evolutionarily conserved epigenetic mechanism that coordinates key life‐history traits.

The tiger salamander as a promising alternative model organism to the axolotl for fracture healing and regenerative biology research

The Anatomical Record, EarlyView.
Abstract Scientists have been captivated by the ability to regenerate, focusing on uncovering the mechanisms of epimorphic regeneration and applying them to human medicine. The axolotl (Ambystoma mexicanum) has become the most intensively studied model in tetrapod regeneration research, particularly concerning limb regeneration.
