The aim of this preliminary study was to evaluate the desirability of alternative models of artificial teeth versus extracted natural teeth for use in preclinical dental education. Specifically, the study was designed to compare the preparation time and perceptions of difficulty of undergraduate dental students and endodontists in carrying out root canal preparations on resin models (both clear...

Mature cystic teratomas are a form of ovarian germ cell tumor and often called ‘dermoid cysts’ because they are mostly cystic. Many teratomas have teeth with morphologically identifiable crowns and roots. The objective of this study was to carry out morphometric measurements of teratomatous teeth extracted from a mature cystic teratoma excised from a 28-year-old female patient. The extracted te...

The aim of this study was to evaluate the viability of periodontal ligament cells of avulsed teeth in three different storage media. Forty-five mature premolars extracted for orthodontic therapeutic purposes were randomly and equally divided into three groups according to the storage medium: milk (control), rice water and egg white. After placing extracted teeth for 30 min in storage media, the...

We examined the caries prevalence and treatment needs of medically compromised and healthy paediatric patients attending the dental clinic of a tertiary care institution in Saudi Arabia. The medical records of 175 healthy and 211 medically compromised 5-year-old Saudi children were reviewed. Data was extracted on clinical status and number of decayed, extracted and filled teeth (deft score). A ...

The consequences of premature loss of temporary teeth are complex, both of functional and morphological order and the clinical presentation depends on multiple factors: the temporary tooth loss rate as compared with permanent tooth eruption sequence and the number and topography of teeth extracted, so the clinical form of edentulous, which can be frontal or lateral, symmetric or asymmetric, iso...

Comparison between two ultrasonic units in shaping curved canals in teeth using macroradiography. cleaning effectiveness of two single-file systems in severely curved root canals of extracted teeth: Reciproc WaveOne versus Mtwo ProTaper. Fidel RAS. The ability of the Reciproc R25 instrument to reach the full root canal working length without a glide path.

People with intellectual disability (ID) usually have a poor quality of oral health, which include poor oral hygiene, untreated caries and high proportion of missing teeth. Due to their fear and repulsive attitude towards medical staff general anesthesia is often a useful method for dental treatment. One thousand and fifty four intellectual disability patients for the period of 1985-2009 who re...

BACKGROUND The purpose of this study was to investigate the reasons for and patterns of extraction of permanent teeth in a subset of the Saudi population. METHODS During a 3-month period, dentists were asked to record, using a specially designed survey form, the reasons for every extraction of a permanent tooth. The reasons for tooth extraction were assigned to different causes, ie, dental ca...

background & aim: regional odonto dysplasia (rod) is an unusual nonhereditary of teeth with significantly clinical and radiographic features. affected teeth usually remain unerupted or semi-erupted with a discolaration and irregular shape. radiographically these teeth have a large pulp chamber and thin layer of enamel and dentin with similar density. this article is introducing a female patient...

The purpose of this study is to determine the influence on four premolar extractions for upper and lower anterior tooth size discrepancy (for total Bolton index (TBI=Overall ratio) and for Bolton value (BV)) and to find out the differences of four first and second premolar extractions tooth size discrepancies (TSD). 148 pretreatment dental casts have been examined. It has been determined that u...
