diagrams to ease the orthodontic diagnosis and treatment of North-American patients. Subsequently, the system was adapted by different authors to other races and populations. The objective of this study is to provide a system of Moorrees-like mesh diagrams for the Romanian population, Caucasian race, which would help orthodontists, surgeons and prosthetists. Methods. 40 patients were introduced in the study, 20 males and 20 females, with ages between 12-33 years, permanent dentition and slight dental-maxillary abnormalities, class I and II Angle. For each patient, a lateral cephalometric radiograph was taken, with CRANEX 3D, head straight, maximum intercuspation. On tracing paper were drawn 35 anthropometric points and 3 planes, Frankfurt plane, as the horizontal landmark, a perpendicular line through nasion as the vertical landmark and the occlusal plane. From each point we measured the distance in millimeters to the horizontal landmark and to the vertical landmark, respectively. The obtained values were introduced into 40 tables, using Microsoft Office Excel 2007 and 3 arithmetic means were calculated, for males, for females and a general one, for children under 12 years old. The arithmetic means were transferred on millimetric paper and tracing paper, joining the obtained points and completing the templates. Results. Three different Moorrees-like mesh diagrams were obtained, one for male, one for female and a mixt one for children under 12 years, Romanian patients, Caucasian race, respectively. Conclusions. Mesh diagram comes in the support of a better perspective of the anatomical elements of the face and the facial growth, being a useful tool in predicting treatment. Computer based programs with Moorrees-like diagrams adapted to Romanian patients may be the object of further studies.

The aim of this study is to demonstrate the use and the effectiveness of cephalometry and golden proportions analysis of the face in planning prosthetic treatments in totally edentulous patients. In order to apply this method, latero-lateral and posterior-anterior X-rays must be performed in addition to the common procedure. Two main concerns for totally edentulous patients are the establishment of the vertical dimension and the new position of the occlusal plane. The divine proportion analysis was carried out by the use of a golden divider. The prosthetic protocol was divided into three steps and a case was selected for better understanding. Referring to the golden relations, if the distance from the chin to the wing of the nose is 1.0, the distance from the nose to eye is 0.618. This proportion is useful and effective in determining the correct prosthetic vertical dimension. The incisal margin of the lower incisor must be positioned between Point A (A) and protuberance menti (Pm) according to the gold ratio 0.618 of the total height A-Pm. Posteriorly the occlusal plane must be placed 2 mm below the divine occlusal plane (traced from the incisal margin of lower incisors to Xi point). A prosthesis made in accordance with cephalometric parameters and divine proportions of the face helps to improve the patient’s aesthetics, function and social personality.

Knowledge of the Eagle's syndrome shows that its symptoms can be very easily confused with other types of craniomandibular disorders, especially temporomandibular disorders (TMD). The aim of this study was to find a possible correlation between the presence of TMD and elongation of the styloid process as well relate to presence of calcification of the stilohyoid chain. Fifty patients with TMD, confirmed from the RDC/TMD, were examined clinically and radiographically. Radiographic documentation consisted of digital panoramic radiograph and digital lateral cephalometric radiograph. Radiocef software (Radiomemory) was used for the analysis of radiographs by means of specific cephalometric tracing and linear measurements of the styloid process. Each radiograph was traced and measured three times with intervals of 1 month to spread the error. Statistical analysis was performed by Pearson's test (p=0.001) using Biostat 4.0 statistical software. Result showed an incidence of 76% elongation of the styloid process in the sample. There was a correlation between the bilateral measures taken in panoramic radiographs (?<0.001) and also for measures of styloid process length carried out in different panoramic radiographs and lateral cephalometric radiographs (?<0.001). It was concluded that there is prevalence of elongated styloid process in patients with TMD. However, no relationship was found between measurements on the stylohyoid chain and symptoms of headache, orofacial pain, tinnitus and vertigo.

Cephalometric Study

Bonded maxillary expansion appliances have been suggested to control increases in the vertical dimension of the face after rapid maxillary expansion (RME). However, there is still no consensus in the literature about its real skeletal effects. The purpose of this prospective study was to evaluate, longitudinally, the vertical and sagittal cephalometric alterations after RME performed with bonded maxillary expansion appliance. The sample consisted of 26 children, with a mean age of 8.7 years (range: 6.9-10.9 years), with posterior skeletal crossbite and indication for RME. After maxillary expansion, the bonded appliance was used as a fixed retention for 3.4 months, being replaced by a removable retention subsequently. The cephalometric study was performed onto lateral radiographs, taken before treatment was started, and again 6.3 months after removing the bonded appliance. Intra-group comparison was made using paired t test. The results showed that there were no significant sagittal skeletal changes at the end of treatment. There was a small vertical skeletal increase in five of the eleven evaluated cephalometric measures. The maxilla displaced downward, but it did not modify the facial growth patterns or the direction of the mandible growth. Under the specific conditions of this research, it may be concluded that RME with acrylic bonded maxillary expansion appliance did promote signifciant vertical or sagittal cephalometric alterations. The vertical changes found with the use of the bonded appliance were small and probably transitory, similar to those occurred with the use of banded expansion appliances.

There are many claims that abnormal breathing patterns alter facial growth; however, there are limited controlled data to confirm these claims. Thirty children with allergy, aged 6 to 12 years, who had moderate-to-severe nasal mucosal edema on physical examination and who appeared to breathe predominantly through the mouth and 15 children without allergy who had normal findings from nasal examination and who appeared to breathe predominantly through the nose were evaluated. All subjects received an intraoral clinical examination and cephalometric radiograph analysis. In comparison with children who breathed through the nose, children who breathed through the mouth had longer faces with narrower maxillae and retruded jaws. This supports the hypothesis that children with nasal obstruction and who appear to breathe through the mouth have distinctive facial characteristics.

Collaborative learning is an activity that takes place between a teacher and a learner, between learner and learner, and sometimes, one would hope, between learner and teacher. The free flow of ideas between the various parties can be inhibited by a variety of factors, including perceived or actual power barriers, language skills, previous learning experience, and personal factors such as shyness or dominance. Technology can be used as a way of overcoming, or reducing, some of these inhibitory factors, and this chapter outlines some of the computer-based technologies that can be used. The use of technology to support distant learners is well documented, and this chapter concentrates instead on the less well-reported use of technology in the face-to-face classroom. The chapter opens with a brief consideration of collaborative learning and then focuses on the technologies that can be used to support collaborative learning process in a variety of time and place settings. These technologies include audience response systems, electronic meeting systems, and more recently, and rapidly developing, blended versions of these technologies.

The research pertaining to two types of cognitive interventions is reviewed. Brain training, which utilizes a variety of computer based approaches, is designed to improve normal performance by developing cognitive skills. Cognitive remediation is designed to improve performance in the face of acquired deficits. Such programs are designed to help patients with existing mild cognitive impairment or dementia. Although not uniform, there is mounting evidence that these interventions have a beneficial effect. However, research also suggests the beneficial effect of such programs is often limited to the specific type of task trained, with generalization to real-life performance more questionable. Patients improve specific cognitive domains that do not necessarily correlate with improvements in activities of daily life. The findings and limitations of current research are discussed along with directions for future research.

Orientation of occlusal plane for complete dentures play a vital role as it affects all the basic requirements of complete dentures. Depending on soft tissue landmarks for orienting occlusal plane seems to be unreliable. Cephalometrics were introduced in Prosthodontics to orient the occlusal plane in the same position as it was with the lost natural teeth. In the present study, 60 lateral cephalometric radiographs of a group of male and female dentulous subjects of Indian and Nepali origin (30 subjects in each group) were obtained and tracings were made. All the subjects selected were in the age group of 20-30 years in whom the facial growth was completed. Angular measurements were made between FH (Frankfort Horizontal plane)- CP (Camper's Plane), FH-OP (Occlusal Plane) and CP-OP and subjected to statistical analysis to determine the degree of separation between these planes in Indian and Nepalese ethnic groups. The absolute parallelism between the natural occlusal plane and Camper's plane were not proven in both Indian and Nepalese subjects involved in this study. This significantly reduces the reference values of these planes in Prosthodontics.

Background. Vertical facial growth has a high prevalence. Nonspecialized professionals have shown low sensitivity to identify patients at risk. In the face of this difficulty, we designed and validated a screening checklist for vertical facial growth. Methods. A multidisciplinary team of 5 members developed the Vertical Facial Growth Screening Test. A sample of 160 evaluations was obtained. We consider as the gold standard the evaluation of 2 specialists in dentofacial orthopedics. Results. Consistency measured with Cronbach α was .675 for 10 items. Test-retest reliability was .956. The interobserver concordance was .886. The receiver operating characteristic curve has .987 area under the curve. Conclusion. This is the first study to design and validate a screening checklist for vertical facial growth for nonexpert evaluators. We think that given its good performance, ease of use, inexpensiveness, and availability, the test could be useful for nontrained professionals dealing with children.

The objective of this article is to evaluate the role of retinoids in the developing head and face. This article covers two lines of evidence that strongly support a role for retinoids in craniofacial development. First, the specific effects of exogenous retinoids on the head and face are covered and mechanisms for the specificity discussed. Second, the function of endogenous retinoids in facial development is discussed in relation to the distribution of retinoid-binding substances in the face. Finally, the interaction of retinoids with other genes known to be expressed in the face as well as other factors required for facial growth is discussed.
