OBJECTIVE To explore how many millimeters of tooth size discrepancy (TSD) are clinically significant, to determine what percentage of a representative orthodontic population has such a tooth size discrepancy, and to determine the ability of simple visual inspection to detect such a discrepancy. MATERIALS AND METHODS The sample comprised 150 pretreatment study casts with fully erupted and comp...

PURPOSE This study investigated the relationship between the roots of the maxillary molars and the maxillary sinus using cone beam computed tomography (CBCT), and measured the distances between the roots of the maxillary molars and the sinus floor as well as the thickness of the bone between the root and the alveolar cortical plate. MATERIALS AND METHODS The study sample consisted of 83 patie...

Bacteriologic samples from 31 young men were cultured quantitatively for aerobes and anaerobes; these samples included 31 specimens of tonsils (16 infected and 15 healthy), 16 specimens from pericoronal pockets of lower third molars (11 infected and 5 symptom-free), and 6 postoperative specimens from lower-third-molar extraction sockets. Anaerobes were isolated more often from infected third mo...

OBJECTIVE To evaluate the Forsus Fatigue Resistant Device (FRD) as a compliance-free alternative to Class II elastics. MATERIALS AND METHODS A sample of 34 (14 female, 20 male) consecutively treated nonextraction FRD patients (12.6 years of age) were matched with a sample of 34 (14 female, 20 male) consecutively treated nonextraction Class II elastics patients (12.2 years of age) based on fou...

The presence of asymptomatic third molars can represent a potential problem in the mandible when these teeth are retained and the patient has lost all normally erupted teeth. Once the mandibular first and second molars are removed, the mandibular body becomes weaker with time, increasing the complexity, morbidity and incidence of complication in the surgical procedure to remove the retained thi...

greater palatine foramen (GPF) is important for enhancing the anesthetic injection technique in the posterior palate for optimal pain control in maxillofacial and dental surgeries. The morphometric measurements of GPF along with distances from midline maxillary sutures were recorded, which are helpful for nerve block. The morphometric study was carried out on 100 adult dry human unsexed skulls ...

background: with the introduction of skeletal anchorage system, recently it is possible tosuccessfully intrude molar teeth. on the other hand, there have been concerns about periodontal changes associated with intrusion and there are few studies on this topic, especially for posterior teeth. materials and methods: ten female patients were enrolled in this study. maxillary molar intrusion was ac...

The objective of this study was to measure the effectiveness of fluoride varnish as a public health intervention to prevent caries on partially erupted first and second permanent molars among 6-11 year old children at high risk for caries. In a six-month clinical trial, 105 children were randomly divided into a fluoride varnish (Duraphat) group (117 molars) or a control group (117 molars). The ...
