Sequelae in permanent teeth after traumatic injuries to primary dentition.

Minerva Stomatol 2019 Dec;68(6):332-340

Department of Biotechnologies and Medical Surgical Sciences, Sapienza University, Rome, Italy.

Traumatic injuries to the primary dentition are critical events in dentistry not only due to the need for urgent care, but also since they have potential sequelae in the permanent dentition, with a prevalence ranging from 12% to 74%. The aim of this article was to provide an overview of the prevalence, etiology, and clinical and radiographic characteristics as well as the management of permanent teeth sequelae resulting from traumatic injuries to their deciduous predecessors. An extensive literature review was performed to reveal the current evidence on enamel discoloration with or without hypomineralization/hypoplasia, crown dilaceration, odontoma-like malformation, root anomalies, partial or complete arrest of root formation, sequestration of the permanent tooth germ, and eruption disturbances.

Comparative Evaluation of Esthetics after Microabrasion and Microabrasion followed by Casein Phosphopeptide-Amorphous Calcium Fluoride Phosphate on Molar Incisor Hypomineralization-Affected Incisors.

Contemp Clin Dent 2019 Jan-Mar;10(1):9-15

School of Dental Medicine, University of Colorado, Denver, Colorado, USA.

Background: Molar incisor hypomineralization (MIH) is an esthetic setback for the patient as well as for the dentist, treatment options for MIH includes minimally invasive techniques like microabrasion which has a limited literature of its effect. Furthermore, the effect of remineralizing such as casein phosphopeptide-amorphous calcium phosphate (CPP-ACP) agent on MIH-affected teeth is minimally studied.

Aim: Comparative evaluation of the esthetic after microabrasion and microabrasion followed by Tooth Mousse Plus on hypomineralized incisors of MIH-affected patients. Read More

Comparative analysis of tooth discoloration induced by conventional and modified triple antibiotic pastes used in regenerative endodontics.

Indian J Dent Res 2019 Nov-Dec;30(6):933-936

Department of Conservative Dentistry and Endodontics, Faculty of Dental Sciences, King George' Medical University, Lucknow, Uttar Pradesh, India.

Background: Success of the regenerative endodontic treatment depends upon the disinfection of the root canal system. Because almost no instrumentation is carried out, the disinfection protocol relies only on the medicaments used. The most commonly used medicament is triple antibiotic paste (TAP) composed of metronidazole, ciprofloxacin, and minocycline. Read More
