ABSTRACT
PURPOSE: The aim of this study was to determine the age, gender, and sites of different types of odontogenic cysts (OCs) and non-OCs (nOCs) (seen in eastern Anatolian population in Turkey. MATERIALS AND METHODS: The following data were collected from the clinical records and histopathology reports of the Department of Oral and Maxillofacial Surgery and the Department of Oral Pathology, Ataturk University, Turkey, during a period of 10 years. They were analyzed descriptively in terms of incidence, age, sex, cyst type, and site. RESULTS: A total of 526 cysts were diagnosed during a 10-year period. Of these, 330 (62.7%) were in males, and 196 (37.3%) were in females, the male:female ratio was 1.7:1. There were 509 (96.8%) OCs and 17 (3.2%) nOCs. There were 406 (77.2%) inflammatory OCs and 103 (19.6%) developmental OCs. Radicular cysts were the most frequent (66.4%), followed by dentigerous (19.2%) and residual (10.8%) cysts. Only nasopalatine duct cyst was found as nOC in this study (3.2%). CONCLUSION: The distribution of jaw cysts in the Turkish Eastern Anatolian population is relatively similar to that of other populations reported in previous studies in the literature, in which most OCs were of inflammatory origin. However, the relative rates of cysts were higher than those reported in other studies.

PURPOSE: The purpose was to examine the prevalence, gender, age and site(s) of odontogenic and nonodontogenic benign tumors, and tumor-like lesions occurring in the oral cavity and jaws in a Turkish population, particularly, in the Eastern Turkey, and to compare findings of this study with other reports. MATERIALS AND METHODS: The data were collected from the files of the Department of Oral and Maxillofacial Surgery and the Department of Oral Pathology, Ataturk University, Turkey, during a 10-year period from January 2005 to January 2015. They were analyzed descriptively regarding prevalence, age, sex, lesion type, and site. RESULTS: A total of 709 benign tumor and tumor-like lesions of the oral cavity, and jaws were selected during a period of 10 years. One hundred and twenty-one of these lesions (17%) were odontogenic benign tumors while 588 (83%) were nonodontogenic benign tumor and tumor-like lesions. CONCLUSIONS: This study revealed that the distribution and characteristics of benign tumors and tumor-like lesions of oral cavity and jaws in the Turkish population, particularly including the Eastern region of Turkey have some differences as well as similarities with the findings of studies in different populations.

Ligneous periodontitis (LP), a rare periodontal disease, is seen secondary to plasminogen deficiency and fibrin deposition. It is characterized by nodular gingival enlargements and progressive destructive membranous periodontal disease. It generally ends with the early loss of teeth. Defective fibrinolysis and abnormal wound healing is the main pathogenesis of this rare disease and should be considered different from other mucosal systemic disorders. In this case report, we describe the management of ligneous periodontitis and ligneous conjunctivitis developing secondary to plasminogen deficiency in a 6-year-old girl.

Morphological and biochemical changes in plant cells are known as important events for adaptation to stress. In this study, in Ctenanthe setosa leaves to which polyamines were applied during drought stress, changes in the activity of peroxidase, reducing sugar, proline and soluble protein levels were investigated. The three common polyamines, putrescine, spermidine and spermine were exogenously treated through the leaves. The polyamines were sprayed onto the leaves at 5 x 10(-5) M. In the leaves to which polyamines were applied the peroxidase activity decreased, soluble protein increased. Also, it was determined that putrescine and spermidine caused an increase in the amount of proline and in reducing sugar. However, increase was not observed in the leaves to which spermine was applied. In addition, we observed an increase in the activity of peroxidase, proline and reducing sugar levels, and a decrease in soluble protein level in the control ones and the leaves to which polyamines were applied during drought stress. As a result, the effect of polyamine on leaf rolling may be explained through the contribution to osmotic adjustment of the increase in proline, reducing sugar and soluble protein contents.
