Objectives The study was designed to evaluate the efficacy of performing a second, repeat anterior maxillary distraction (AMD) to treat residual cleft maxillary hypoplasia. Materials and Methods Five patients between the ages of 12 to 15 years with a history of AMD and with residual cleft maxillary hypoplasia were included in the study. Inclusion was irrespective of gender, type of cleft lip ...

OBJECTIVES Impacted teeth, if left untreated, have a potential to induce various complications. The aim of the current study was to determine the prevalence and pattern of impacted mandibular third molar in the Iranian population. STUDY DESIGN This cross-sectional study was performed in patients who were referred to the Department of Oral Radiology between July 2009 and October 2010 to obtain...

BACKGROUND Retromolar trigone squamous cell carcinoma is relatively uncommon and due to its complex anatomy has always remained a challenge in terms of loco-regional control and survival. Surgery, radiotherapy, and chemotherapy as combined modalities have been used but high recurrence rates result in poor outcome. METHODS We have retrospectively evaluated records of 62 patients treated in Hea...

AIM A cross-sectional radiographic orthopantomogram (OPG) survey was done to determine the prevalence of apical periodontitis (AP) in root canal-treated teeth in a selected population, and to evaluate the influence of the coronal restorations (CR) and root canal fillings on the periapical status. MATERIALS AND METHODS A total of 250 OPGs were evaluated out of which root canal treatment (RCT) ...

The aim of the present investigation was to reconstruct the chronological age based on the dental developmental stages of third molars evaluated on orthopantomograms. A total of 1175 orthopantomograms were assembled from patients of Caucasian origin between 16 and 22 years of age. Each third molar present was scored by two observers according to a 10-stage developmental scale. The kappa statist...

The Purpose of current study is that Osteoporosis is a systemic disorder characterized by low bone mass leading to fractures reported commonly in females after menopause. The investigations for osteoporosis most commonly used DEXA are very costly and not easily available. Few studies have proposed the use of orthopantomogram as a diagnostic marker for osteoporosis as it is simple, quick, easy, ...

ackground and aim: It is important to evaluate the effect of the type of filling material on deformation and strength of tooth after filling and also the effect of filling depth on quality of restoration of a decayed tooth. Material and Methods: The Orthopantomogram (OPG) of the first and second molars of a 28-year-old man was made and the teeth were 3D modeled. The stress-deformation analysis ...

Today, the diagnosis of orthodontic patients is carried out according to generally accepted method using orthopantomogram, lateral and direct cephalogram with their subsequent analysis, as well linear angular measurements various parameters.
 However, reliability depends quite strongly on position head 2D radiography, need obtain additional radiographs this, because there are significant l...
