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 and aim: formocresol (fc) is yet, the most common medication used for pulpotomy of primary teeth. however, its potential hazards including toxicity, mutagenicity and even some degrees of carcinogenicity are the remaining sources of concern to clinicians. this investigation was aimed at comparing the clinical success level of mta (case) treated pulps of primary teeth to that of formoc...

OBJECTIVES The purpose of the present study was to retrospectively analyze 170 case series of patients with 200 impacted first and second permanent molars. STUDY DESIGN Records of 104.408 patients were retrospectively screened in this multicenter study. The chosen study population consists of 170 patients who presented with impacted or retained first and second permanent molar. All patients w...

The radiographic anatomy of the superior borders of pulpal chambers of primary molars was studied to clarify interpretation of superimposing cuspal images. First and second maxillary and mandibular molars were sectioned transaxially in the cervical region. The pulpal tissue was replaced by radiopaque resin before embedding the crowns in clear plastic blocks and obtaining buccolingual radiograph...

introduction: adequate seal of iatrogenically perforated area within the root canal system can improve the long term treatment prognosis. this in vitro study evaluated the sealing ability of mineral trioxide aggregate (mta), calcium-enriched mixture (cem) cement and biodentine in repair of furcation perforation in primary molars. methods and materials: a total of 61 freshly extracted primary ma...

statement of the problem using cbct to determine root morphology minimizes rate of treatment failure and adverse effects, such as gouging and perforations. purpose the aim of this study was to assess morphology of root canals using cbct scans. materials and methods in this cross-sectional study, conducted in the radiology department of hamadan dental school in 2011‒2012, 66 cbct scans were stud...

Introduction: Composite resins undergo microleakage due to polymerization shrinkage particularly when located in enamel free margins. The purpose of this study was to assess and compare the  microleakage of two nanohybrid  flowable composites and resin modified glass ionomer in class V restorations of primary mandibular second  molars.  Materials and Methods: This in vitro, experimental study ...

UNLABELLED Need for the study: The most important procedure for a successful endodontic treatment is the cleaning and shaping of the canal system. Understanding the internal anatomy of teeth provides valuable information to the clinician that would help him achieve higher clinical success during endodontic therapy. AIMS To evaluate by computed tomography-the internal anatomy of mandibular sec...

Fluoride-containing restorations were placed on the distal surface of primary second molars to evaluate their effectiveness in controlling caries on the mesial surface of the approximating permanent first molars. A half-mouth study design was used with the control primary second molars in the same arch, either restored with amalgam or left sound. After two years, radiographs of 56 pairs of perm...

Acute inflammation is frequently seen in the elderly around incompletely impacted molars located apart from molars or premolars. To identify the factors causing acute inflammation in the solitary molars without second molars or without second and first molars, ages of patients and rates of acute inflammation in 75 horizontal incompletely impacted mandibular molars in contact or not in contact w...
