Nickel Release and the Viability of Streptococcus mutans Corresponding to Low Risk of Dental Caries in Artificial Saliva Containing Orthodontic Appliances: In Vitro Study.

Objective: The aims of this study were to determine the effect of different levels of Streptococcus mutans that correspond to a low risk of dental caries on nickel release and to determine the viability of S. mutans.

Methods: Simulated fixed orthodontic appliances composed of copper nickel titanium, nickel titanium, or stainless steel were immersed in Klimek artificial saliva for 10 days with or without S.

Effects of Positioning Errors Onto the Ratio and Angle Measurements in Photographs of Patients With Unilateral Cleft Lip and Palate.

Background: Nasolabial esthetics is 1 of the most important issues in the evaluation of treatment outcomes in patients with unilateral cleft lip and palate (CLP). Frontal and basal view photographs are commonly used to evaluate nasolabial esthetics in patients with unilateral CLP. High-quality photography plays an important role in evaluating the treatment outcomes and poor quality photographs can result in errors, whereas evaluating the treatment results.

Effect of Cleft Width on the Outcome of Presurgical Nasoalveolar Molding in Patients With Unilateral Cleft Lip and Palate.

The purpose of this study was to investigate the short-term effects of presurgical nasoalveolar molding (PNAM) according to cleft width (CW) in patients with unilateral cleft lip and palate (UCLP). In this retrospective study, 32 newborns with nonsyndromic UCLP treated with PNAM were allocated to 2 groups based on CW (group A, CW ≤5 mm; and group B, CW >5 mm). The following measurements were carried out using standardized photographs taken before and after PNAM therapy (before primary lip surgery): nostril axis inclination of healthy (NAI-NC) and cleft sides (NAI-C), columellar angle (CA), nasal base inclination (NBI), nasal floor width ratio (NFWR), alar base height ratio (ABHR), and columellar length ratio.

A New Approach to Presurgical Nasoalveolar Molding in Patients With Unilateral Cleft Lip and Palate and Severe Cleft Width.

The aim of this study was to describe a new approach to the presurgical orthopedic treatment of unilateral cleft lip and palate patients with severe cleft width. Modified nostril retainers manufactured from soft acrylic were used for the nasal molding. This technique enables the separation of the nasal molding without having to reduce the cleft width to 5 mm.

Modifications in Presurgical Nasoalveolar Molding Treatment of Bilateral Cleft Lip and Palate Patients With Severely Malpositioned Premaxillae.

Objective: The aim of this study was to evaluate a modified presurgical nasoalveolar molding (PNAM) treatment for patients with bilateral cleft lip and palate (BCLP) with severely malpositioned premaxillae.

Setting: This study was conducted at the Faculty of Dentistry, Department of Orthodontics, Ege University, Bornova, Izmir, Turkey.

Method: Retention arms were manufactured using a mold that we developed, and prefabricated retraction apparatuses were applied to the plaster model obtained from the patient.

Presurgical Orthopedic Treatment Using Modified Nostril Retainers in Patients With Unilateral Cleft Lip With or Without Cleft Palate.

This study aimed to present a new technique for presurgical orthopedic treatment of patients with unilateral cleft lip with or without cleft palate (UCL±P) by means of modified nostril retainers manufactured using a special mold with soft acrylic or orthodontic acrylics material. Nasal molding with the modified nostril retainer is considerably effective and comfortable for the patient.
