Angiolipoma of the cheek

Angiolipoma is a benign mesenchymal Lesion that is mainly occures on trunk, arm and forearm as a subcutaneous nodule. The occurrence on head and neck is rare.In this article, we are going to review and present a new and unusual care of angiolipama.

Ellis Von Creveld Syndrome

One patient with Ellis Von Creveld syndrome contains: dwarfism, congenital heart disease, ectodermal dysplasia, polyductyly, an abnormally wide labial renum and maxillary molars with single root.

Odontogenic Cysts

A. Forouzandeh

The goal of this review was to determine the prevalence of cysts in the oral and maxillofacial regions, specially odontogenic cysts, as determined by age, sex and location.This research reviewed 6826 biopsies from department of oral pathology school of dentistry at the medical sciences university of Tehran from 1360-1376 (1981-1997).The results obtained revealed that 19.48% of biopsy lesions were cysts of osseous structures, of which 81.9% were odontogenic cysts, 12.4% psuedocyst and 5.7% were Non- odontogenic in origin.The most common lesions of the oral cavity were odontogenic cysts of which the subgroup of radicular cysts (which belong to the category of inflammatory odontogenic cysts) consisted of 49.15% radicular cysts occurred with the higher incidence in males in their third decade of life and were found most commonly associated with the upper jaw.Dentigerous cysts fall in the second most common group at 25.71% of odontogenic cysts.These cysts had a male predilection with a peak incidence in the second decade and were most common in the lower jaw.In the third group were the keratinized odontogenic cysts at 19.25%. These cysts had a male predilection with a peak incidence in the third decade and the lower jaws were twice as likely to be involved as the upper jaw. Other types of odontogenic cysts were noted to be less common in occurrence.In this study it was discovered that mcoceles consisted of 63.5% of pseudocysts and were found most commonly in the lower lip, with surgical ciliated cysts at 33.7% were the most common Non- odontogenic cysts and were found exclusively in the upper jaw adjacent to the maxillary sinus.Over all it can be stated that about y5 of all oral and maxillofacial lesions were cysts.The most common cysts were odontogenic cysts which due to their higher prevalence and various types, most be carefully examined at the histopathological level to diagnose and therefore administer definitive treatment.

Evaluation prevalence of T cell dysfunction in adult children with chronic muco‌cutaneous candidiasis under 10 years in Pediatric Medical Center of Tehran

Z. Tohidast

Since 1800, it is known that fungican invade human tissues and from 1900, there is a great deal of information about incidence and epidemiology and geographic distribution and fungal infections.Because of increased incidence of fungal infections on recent years and importance of these organisms in producing of systemic and muco- cutaneous diseases, many investigations are performed about these fungal.22patients was evaluated immunological)' and it was revealed that, 77% of patients had increased immunoglubin serum level that was denoted of a normal B. lymphocytes function. As a matter of fact, both immune system are involved in anti- candidia defence, humoral immunity inhibits the penetration of Candida into mucous membranes, skin and internal organs.

Evaluation of the eruption lime of canine, first and second premolar between eight to fourteen years old Isfahanian students

Eruption is a kind of development move of tooth from the place of its formation to its functional position in the mouth.Time and sequence of permanent's teeth eruption from the point of health diagnosis and orthodontic treatments is very important.Because of this, we decided to evaluate and determine the mean eruption time of canine and premolars from gum penetrations toward occlusion and also their sequence of eruption.The average time of eruptions in this study was higher than other similar studies.Our findings showed that the mean eruption time of canine and premolars in girls is earlier than boys lower canines erupt earlier than upper ones and maxillary premolars erupt before mandibular premolars in boys.

Evaluation of statistical correlation between the skeletal angular analysis ANB with the linear analyses wylie, wit, harvold and schwarts

According to different studies - especially geometric ones - different factors have been proposed that can affect horizontal dimension parameters. The aim of this study is claimed on the title. The study is of a descriptive and cross- sectional type.Fourteen lateral cephalogerams were selected to the sample consisted of 21 boys and 19 girls with the mean age of 9.83 years who suffered from different skeletal & dental malocclusion and were selected by simple sampling method.The linear parameters of wit's and wylie (which depend on occlusal & FH planes), the harvold parameter (which is independent of reference planes) & the proportional parameter of Schwartz were selected & their correlation with angular parameter of ANB were evaluated.

The results showed:1- All of the horizontal analyses showed statistically significant correlation.2- The ANB parameter showed high correlation with wit's, wylie, harvold & shawartz analyses and the correlation between ANB & wit's was higher than others.

Evaluation the prevalence of permanent anterior crown fracture and its relevant between 7-14 years students in Tehran, year of 1375

Anterior tooth crown fracture in children is something that each dentist will confront many times during his professional career.We studied the prevalence of anterior teeth crown fractures between 7-14 years old students in Tehran and some relevant factors like sex, age, the traumatized tooth, amount of overbite and overjet, upper lip coverage, jaw that had fractured tooth or teeth and place of fracture in fractured crown.1338 boys and 1184 girls were in this study. Tooth fracture was almost the same in boys and 1184 girls with the prevalence of 8%. Fracture was mostly in enamel and average year of fracture was 10 years.Increased overjet and overbite had direct relation and indirect relation with fracture, also enough lip coverage showed less fracture.

The antero posterior relation of maxilla with saddle angle

Facial prognathism, which is a problem in some orthodontic patients, is characterized by a number of cephalometric changes. Most clinicians use SNA angle in lateral cephalometric analysis to evaluate the amount of maxillary prognathism. Since SNA angle is not a reliable measurement for maxillary prognathism, and taking into account that the amount of prognathism changes in relation to cranial anatomy, according to Bjork it's better to measure the facial prognathism by the angle between anterior and posterior cranial base. According, two angles are recommended NSBa and NSAr.In this study 80 lateral cephalograms from three malocclusion groups, were studied and the amount of maxillary prognathism in relation to SNA and NSAr angles and their relationship to each other were measured.

The results were as follows:
1- Studying facial prognathism in relation to SNA and NSAr angles it was found that SNA angle is influenced by cranial base shape
2- The mean value of anterior and posterior cranial bases didn't show significant differences.
3- The mean value of SNA angle didn't show significant statistical difference in various malocclusion groups.
4- The correlation coefficient of ANB angle and wit's measurement is low.
