introduction: the aim of this in vitro study was to compare the amount of apically extruded debris after root canal preparation using rotary and reciprocating systems in severely curved root canals. methods and materials: thirty six extracted human mandibular first molars with 25-35 ° curvature in their mesiobuccal (mb) canal (according to schneider’s method) were cleaned and shaped with protap...

Justification: the article describes application of a successful technique autotransplantation wisdom teeth as an additional method restoring dentition in patients with impending removal first or second molars.
 
 Objective: goal our work is to assess effectiveness instead extracted tooth (first molars).
 Methods: includes 30 aged 22 38 years who were treated (from January 2016 A...

Kissing molars (KM) or rosette formation is a term that is used to describe impacted teeth contacting occlusal surfaces in a single follicular space and their roots pointing in opposite directions. In some cases kissing molars can be seen but occurrence of bilateral kissing molars is extremely rare phenomenon in the dental literature and the aetiology of this phenomenon is still unknown. In thi...

AIM To determine the prevalence of MIH in 8- and 9 year-old children in the city of Kljuc, Bosnia-Herzegovina, and to describe the distribution and severity of the affected teeth. MATERIALS AND METHODS Study design: All 8- and 9-year-olds (n=104) living in Kljuc (born 2004/2005) were invited to participate, and 103 were examined by a calibrated clinician. Written, informed consent was obtaine...

BACKGROUND Scientific literature estimates that around 18 to 40 % of asymptomatic third molars are extracted. The aims of the present study were to determine the indications for extraction of asymptomatic lower third molars in a sample of Spanish and Portuguese dentists, and to relate these indications to the clinicians' training and professional experience. MATERIAL AND METHODS A survey cons...

AIM This was to evaluate the effect of different thicknesses of cavity walls on fracture strength of pulpotomized primary molar teeth with class II amalgam restorations. METHODS 80 carious extracted human primary molar teeth were selected for pulpotomy preparation. The teeth were divided into four groups. Mesio- or disto-occlusal (20 teeth) and mesio-occluso-distal (20 teeth); cavities were p...

BACKGROUND Successful treatment of molar furcation defects remains a challenge in clinical practice. Knowledge of anatomic factors facilitates predictable management of furcation involvement lesions. The degree of success in managing furcation involvement is inversely related to the horizontal probing depth. The depth of the horizontal component of attachment loss can vary depending on the exte...

BACKGROUND The aim of this study is to evaluate the change in pulp chamber temperature during the stripping technique. METHODS Seventy-eight proximal surfaces of 39 extracted human teeth were stripped by two techniques: double-sided perforated stripping disk (PSD) and handheld stripper (HS). The teeth were divided into three groups: incisors (group 1), premolars (2), and molars (3). A J type ...

This study evaluates the depth of sodium hypochlorite (NaOCl) penetration into dentinal tubules by using the GentleWave® System versus ultrasonic agitation. Forty extracted human molars were accessed and instrumented to size #15 with taper .04, cleaned to remove pulp tissue, immersed in crystal violet dye, and incubated (37°C) overnight. Samples were rinsed with distilled water for 30 minutes a...
