OBJECTIVES The aim of this study was to investigate the possibility to use high-frequency ultrasound imaging for the assessment of periodontal structures. MATERIAL AND METHODS A commercially available ultrasound scanner (Ultrasonix SonoTouch) with a linear 1.5 cm footprint, wideband 8 - 40MHz transducer was used, with external transcutaneous approach. A number of 4 patients with healthy perio...

UNLABELLED AIM The purpose of this study is to present a new clinical approach for the treatment of upper lateral incisor agenesis. MATERIALS AND METHODS A new treatment option was conceived and applied: posterior space opening as a safeguard of occlusal integrity and dental and periodontal aesthetics of the front teeth. This is acheved by means of the anterior space closure, with the mesi...

This study investigated the change in interproximal force (IPF) in mandibular anterior teeth during retention and the relationship between the irregularity index before orthodontic treatment and the IPF. The effect that an erupting third molar had on IPF was also examined. Forty treated patients (40 with extraction of four bicuspids) were followed for 18 months during the retention phase. The i...

The slow adoption of sealants into dental practice is attributed partly to the fact that few prepayment plans pay for sealants. An important concern of insurers is how a sealants benefit will affect premiums. In this analysis, caries rates for various surfaces and teeth, failure rates for both sealants and amalgam restorations, fees and copayments, interest rates, reimbursement policies for rep...

Stains and stained incipient lesions can be challenging to differentiate with established clinical tools. New diagnostic techniques are required for improved distinction enable early noninvasive treatment. This in vitro study evaluates the performance of artificial intelligence (AI)-based classification hyperspectral imaging data occlusal lesion detection differentiation from stains. Sixty-five...

OBJECTIVE The aim of this study was to compare the consumption of dental treatment among patients with Crohn´s disease (CD) or ulcerative colitis (UC) compared to age and gender matched control groups. DESIGN The study group comprised 2085 patients with CD and 3161 with UC from the Uppsala-Örebro region and from the Stockholm region. The patients in the cohort were diagnosed between 1960 and ...

BACKGROUND A new fibrin adhesive made of buffalo plasma-derived fibrinogen and a thrombin-like snake venom enzyme, has been successfully used to immobilize free gingival grafts. This case series histologically compared sutured grafts (control group) with others immobilized by using the fibrin adhesive (experimental group). CASE DESCRIPTION The grafts were placed in the contralateral mandibula...

The purpose of this study was to assess the healing of periapical tissues using three different materials (IRM [L.D. Caulk Inc, Dentsply International Inc, Milford, DE], Geristore [Den-Mat, Santa Maria, CA], and MTA [ProRoot MTA; Dentsply Tulsa Dental Specialties, Tulsa, OK]) after endodontic microsurgery in an animal model. Using beagle dogs as a study model, 48 bicuspids were accessed, instru...

OBJECTIVES The aim of this report is to present the results of a scanning electron microscopic study on the presence of matrix vesicles (MVs) found in human dentine. STUDY DESIGN Dentin tissue from 20 human bicuspids was analyzed by means of scanning electron microscopy. RESULTS MVs were found as outgrowths of the cellular membrane of the odontoblastic body, the more proximal portion of the...

The aim of this study was to compare the quality of image registration of two computer programs by means of digital subtraction radiography (DSR). The sample comprised 294 direct digital periapical radiographs. This sample was obtained from a previous study in which 49 mandibular teeth (central incisors, laterals incisors, cuspids and bicuspids), were radiographed with 6 different x-ray beam an...
