Isolated bilateral macrostomia: literature review and case report.

Aim: Macrostomia, or lateral cleft lip, which is known as Tessier cleft type 7, is one of the rarest facial anomalies. The purpose of this review is to describe the main characteristics, epidemiology, aetiology and treatment of this anomaly.

Methods: We present an overview of surgical techniques as well as a review of all 36 cases of bilateral asyndromic macrostomia reported to this da in the literature.

Remineralization effects of Er,Cr:YSGG and/or bioactive glass on human enamel after radiotherapy-an in vitro study.

The aim was to evaluate the effects of Er,Cr:YSGG and/or bioactive glass 45S5 (BG) on the chemical and physical properties of enamel after radiotherapy. Third molar crowns were cut in half (buccal-lingually), and the mid part of the labial/oral surface was subjected to different protocols. All samples were treated with standard 70 Gy.

Effect of adhesive coating on calcium, phosphate, and fluoride release from experimental and commercial remineralizing dental restorative materials.

This study investigated the potential of adhesive coating for hindering the reactivity of ion-releasing dental restorative materials. Experimental composites were prepared by replacing 10 or 20 wt% of reinforcing fillers with two types of bioactive glass. A glass ionomer, a giomer, and an alkasite were used as representatives of commercial ion-releasing materials.

Ion release and hydroxyapatite precipitation of resin composites functionalized with two types of bioactive glass.

Objectives: To prepare experimental composites with bioactive glass (BG) and investigate their release of calcium (Ca), phosphate (PO), and fluoride (F), as well as pH changes and apatite precipitation after immersion.

Methods: Experimental composites were prepared with 0, 10, or 20 wt% of either BG 45S5 or a customized low-Na F-containing BG. Three commercial ion-releasing materials were used for reference.

Direct Induced Effects of Standard and Modified Radiotherapy Protocol on Surface Structure of Hard Dental Tissue.

Introduction: Radiotherapy is used to treat neo plasmatic lesions and the common side effects of this process are pain, swelling and sensitivity of mucous membranes in domain of radiation, reduced salivation, caries, and periodontal disease and, in total, low life quality. The purpose of this research was to estimate the outcome of direct irradiation on physical and surface characteristics of hard dental tissues.

Materials And Methods: Twenty, caries free third molars were involved in the research.
