PURPOSE The purpose of this in vivo study was to compare the accuracy of primary incisor length determined by direct digital radiography (straight-line measurement and grid superimposition) and measurement of the actual tooth length. METHODS Twenty-two primary maxillary incisors that required extractions were selected from 3- to 5-year-old children. The teeth were radiographed with an intraor...

OBJECTIVE The aim of this study was to detect the prevalence of selected bacterial species in intraoral sites of patients with chronic periodontitis (CP) using multiplex polymerase chain reaction (PCR). METHODOLOGY Samples were collected from the tongue dorsum, buccal mucosa, supragingival and subgingival plaque and saliva of 30 patients with untreated CP. Multiplex PCR was used to determine ...

OBJECTIVE To compare the use of the 5-year-olds' index on both dental study casts and intraoral photographs when measuring primary surgical outcome for children born with unilateral cleft lip and palate (UCLP). DESIGN A cross-sectional study. SETTING Models and photographs collected from cleft units across the UK as part of the CCUK (Cleft Care UK) study were scored by two clinicians at the...

Purpose: Root fracture is a clinical problem which often is difficult to detect and diagnose. As the root fracture detection is based on demonstration of a fracture line or lines, radiographic examination is important. The aim of this study was to compare diagnostic efficacy of direct digital radiography with conventional radiography for detecting experimental root fractures. Materials & Method...

The objective of this study was to evaluate the marginal and internal fit of zirconia copings obtained with different digital scanning methods. A human mandibular first molar was set in a typodont with its adjacent and antagonist teeth and prepared for an all-ceramic crown. Digital impressions were made using an intraoral scanner (3Shape). Polyvinyl siloxane impressions and Type IV gypsum model...

BACKGROUND To date, no studies have been published that evaluated histomorphometric data from a large number of patients while comparing different sites and methods of autologous bone grafting in sinus floor augmentation procedures. A meta-analysis of the English literature from January 1995 till April 2009 was carried out. MATERIALS AND METHODS PubMed search engine and the following journals...

Three-dimensional imaging may aid in complementing intraoral and panoramic radiography during the diagnosis of tooth eruption disturbances. The purpose this study was to investigate teeth affected by disturbances patients referred for cone-beam computed tomography （CBCT）. analysis included 134 113 ＜20 years age who demonstrated （excluding wisdom teeth） were CBCT imaging. Factors analyzed includ...
