Moving on trial: protocol for a pilot randomised controlled trial of models of housing and support to reduce risks of COVID-19 infection and homelessness.

Background: It is estimated that around 160,000 households in Britain experience homelessness each year, although no definitive statistics exist. Between March and September 2020, as part of the initial 'Everyone In' government response to COVID-19 in England, 10,566 people were living in emergency accommodation and nearly 18,911 people had been moved into settled accommodation. However, some forms of temporary accommodation may not be suitable as shared facilities make it impossible for people to adhere to government guidelines to reduce the spread of COVID-19.

Dietary Habits and Abdominal Pain-related Functional Gastrointestinal Disorders: A School-based, Cross-sectional Analysis in Greek Children and Adolescents.

Background/aims: The abdominal pain-related functional gastrointestinal disorders (AP-FGIDs) affect a significant proportion of the pediatric population and consist 1 of the most frequent causes for seeking medical advice. In this study, we aimed to assess the relation of dietary habits with the likelihood of AP-FGIDs.

Methods: This was a school-based, cross-sectional study approved by the Greek Government authorities, after obtaining informed consent by the legal representatives of the children.

Oral health status in Greek children and teenagers, with disabilities.

Nowadays there is a sharp increase of population with disabilities. The aim of this investigation was a) to survey the dental health status, estimate the treatment requirements of children and adolescents with cerebral palsy, mental retardation and visual disorders and b) to compare the oral health status of these groups of individuals. The investigation entailed the clinical examination of 170 individuals, between 6 and 15 years old, who were attending four special schools in Athens, Greece.

A survey on supernumerary molars.

The contemporary literature concerning the etiology, frequency, and classification of supernumerary teeth, specifically molars, is reviewed in this article. Also, methods for their early detection, as well as the prognosis and treatment of supernumerary molars, are discussed. Eight cases at the University of Athens and 105 others obtained from the literature were subjected to statistical analysis to examine sexual dimorphism and the position, impactions, and bilateral presence of supernumerary molars.

Classification of human maxillar sinuses according to their geometric features.

119 casts of maxillary sinuses have been taken out of 60 dry skulls. In these specimens, the volume V, the area of the basal (i.e.

[Anatomical and radiographic study of the sinus floor distance from the alveolar crest in edentulous area of skulls].

The distance between the floor of the maxillary sinus and the alveolar crest in edentulous areas (where the 2nd bicuspid 1st and 2nd molars were previously located) were studied both anatomically and radiographically. The material consisted of 22 skulls in which 33 edentulous maxillary areas were found. Direct anatomical measurements were performed and measurements on periapical radiographs were made.

Orientation and eruptive patterns of the mandibular second premolar.

Distal migration of the mandibular second premolar into a first molar extraction site is a clinical finding often correlated with the early loss of a permanent mandibular first molar. Signs of this tendency can be detected radiographically as early as 6 to 7 years of age when the mineralization of the crown of the mandibular second premolar is almost complete. The results of a study of 2000 panoramic dental radiographs of children, aged 8 to 18 years, are reported.

[Radiographic study of odontomas].

Odontomas are the most common benign odontogenic tumors with a high degree of differentiation and an excellent biological behavior. Three histological types are recognised: a) ameloblastic odontoma, b) coplex odontoma and c) compound odontoma. Usually these tumors are asymptomatic and the most frequent cause of discovery is the retention or impaction of a permanent tooth.

[Morphology of the sphenoid bone in individuals with syndromes which affect the craniofacial complex].

Anatomically, the sphenoid bone can be characterized as the center of the skull. It represents the crossroads where various factors which contribute--each in its own way--to the craniofacial complex, are combined. The morphology of the sphenoid bone is changeable and the opinion that it serves the functional needs for the viability of the individual was formulated in the literature.

[The use of periapical X-rays in the identification of a corpse].

The authors describe the procedure followed in the identification of a corpse by means of findings gathered from periapical X-rays. The interesting point about this identification is that it was practically based on one single tooth; The dental periapical X-rays of the person to which the body was suspected to belong, revealed certain peculiarities in the root outline and the endodontic treatment of an upper second right premolar. An X-ray of the corresponding tooth of the corpse was taken and the same identical findings were seen, thus documenting the identity of the corpse.

[Changes in the radiographic picture of various locations of the mandible, after long-term use of oral contraceptives].

The vast use of oral contraceptives by a large percentage of women, in our days, has caused increased interest as regards the side effects that these "pills" might have. The purpose of this article was firstly, to review the mechanism of action of the estrogens contained in the contraceptive pills and to emphasize the possibilities that longterm use of these drugs may have in producing changes in the bones of the jaws. Subsequently, the authors describe the results of observations made in periapical X-rays taken for this matter at the Dental School of Tufts University.

[Three cases of Rubinstein-Taybi syndrome].

Manifestations from the craniofacial complex in patients presenting with the Rubinstein-Taybi syndrome, are of a special interest to the dentist as they involve structures of the oral cavity. On the occasion of three cases that exhibit some of the characteristic signs of this syndrome, the authors provide an extensive review of the related literature. Also, the specific morphology of the face, fingers, and oral structures of these patients is described, as well as, the findings from their cephalometric radiographs.

[A clinical and epidemiological study of Tori mandibularis].

This is a study aiming at: a) reviewing the information found in the relevant literature as regards the etiology, incidence, distribution, implication and management of the tori mandibularis, b) evaluating the incidence, location and morphology of this bony mass in a sample of Greek population and c) comparing the findings with those of other investigators. The material consisted of 357 patients, from 20 years old and onwards, who had consecutively visited the Clinic of Removable Prosthodontics for some problem. After clinical examination and tabulation of the findings, the following conclusions were drawn: a) the etiology of appearance of tori mandibularis remains unknown; b) in our sample, 12.

[The incidence of superimposition of permanent teeth in the orthopantomographs and in radiographs Status-X].

In this study 82 orthopantomographs and 82 Status-x radiographs of the same patients were evaluated in order to determine the incidence of superimposition of teeth in the two kinds of panoramic radiographs. The patients were 10 to 20 years of age and presented no crowding as judged clinically or from respective plaster casts. The results of this study showed that the superimposition occurs in 71.

[Ten cases of supernumerary premolars and review of the literature].

In this study, the modern literature concerning the classification and the incidence of supernumerary teeth and specificly premolars, is reviewed. Extensive reference is given to the aetiology and pathogeny of the existence of supernumerary teeth and the main theories that have been stated until now are described. The diagnostic problems that may result from these are discussed, as well as the methods and ways of their early detection.

[Comparative study concerning the magnification of anterior permanent teeth of the upper jaw in the Status-X radiograph and in the orthopantomograph].

Measurements of the mesiodistal diameters and the total length of anterior permanent teeth of the upper jaw were performed in 82 status-X radiographs and in 82 orthopantomographs of the same patients, in order to determine the difference of magnification in the two kinds of radiographs. The findings proved that the difference of magnification of the mesiodistal diameters ranges from 82.08% to 90.

[Identification of a body from dental findings].

The author starts by briefly reviewing the meaning and applications of Forensic Dentistry emphasizing the ethical and legal responsibility of the dentist who is called upon by the police and the Service of Forensic Medicine to contribute to the identification of a dead person. Next, the author describes an interesting case where the identification was possible by documenting more than ten points coinciding between the dental record of the person suspected to be the dead and the findings from the examination of the oral cavity of the body.

[Findings from the clinical examination of the oral cavity of one hundred drug addicts].

The authors studied the findings from the clinical examination of the oral cavity of one hundred drug addicts that were prisoners at Korydalos prison, in order to evaluate the incidence and the possible correlation of these findings to the drug abuse. This study revealed that drug addicts present lesions of the oral mucosa such as redness of the pharyngeal mucosa (57%), melanchromatic spots on the lips (35%) and hairy tongue (57%). Also, a high incidence of carious lesions was found (46%), of missing teeth (42%) and of periodontal disease (57%).
