IntroductionRecurrent Aphthous Stomatitis (RAS) is a common oral mucosal disorder which is characterized by recurrent ulcerations mainly confined to non-keratinized oral mucosa. Though the exact etiology is imprecise, stress and anxiety were found to be linked with the onset of RAS. The present study was directed to know the prevalence of RAS among female dental students in King Khalid University, to find out the association between RAS and psychological stress and the effectiveness of Hospital Anxiety and Depression scale (HADS) in finding out the psychological profile of RAS patients.Method122 female dental students of age group 17 to 25 years were selected for the study. Subjects with relevant medical problems and deleterious habits were excluded. A questionnaire comprising general stress related questions and HAD scale were used to assess stress. Those who were giving history of ulcer were diagnosed as RAS based on the clinical features. The questionnaire results were used for statistical analysis and processed.Result14% of the total students were having RAS. 70% could correlate the onset of ulcer with certain specific factors; stress being the major causative agent (91%). In HAD scale, 88% of students were having anxiety and 65% had depression; all patients with depression had anxiety.ConclusionThe prevalence of RAS in female dental students in KKU was around 14%. There is a strong relationship between psychological stress and RAS, as in most of the other studies. HAD scale alone can be used for detecting the psychological factor in RAS.

Background. Osteoblastoma is a rare benign tumor. This tumor is characterized by osteoid and bone formation with the presence of numerous osteoblasts. The lesion is more frequently seen in long bones and rarely involves maxilla and mandible. Due to its clinical and histological similarity with other bone tumors such as osteoid osteoma and fibro-osseous lesions, osteoblastoma presents a diagnostic dilemma. Case Report. Very few cases of osteoblastomas involving maxillofacial region have been reported in the literature. This case report involves osteoblastoma involving right maxilla in an 18-year-old male patient. Following detailed clinical examination, radiological interpretation, and histopathological diagnosis, surgical excision was performed. The patient was followed up for a period of 3 years and was disease free. Summary and Conclusion. Benign osteoblastoma involving jaw bones is a rare tumor. There is a close resemblance of this tumor with other lesions such as fibro-osseous lesions and odontogenic tumors and thus faces a diagnostic challenge. Surgical excision with a long-term follow-up gives good prognosis to this lesion—Benign Osteoblastoma.

Objective:To estimate the age of an individual between 13 and 23 years, using Demirjian method in Saudi male patients in the southern region of the Kingdom of Saudi Arabia.Materials and Methods:A total of 360 male patient's digital panoramic radiographs were used to evaluate the morphology of mandibular 3rd molar teeth roots according to the Demirjian method. Using descriptive statistical method, age was calculated.Results:Result showed a strong relation of age with stages of root development of 3rd molar teeth. The standard deviation of mean of root development stages is 1.47 years of age.Conclusion:This study suggests that age can be predicted with a statistical significant result for ages between 13 and 23. Further studies with large population are needed for better statistical results and for female age assessment.

Background: Pulp stones are calcification in the dental pulp which can be present either in deciduous or permanent teeth. Exact causes of pulp stones are not known and several elements have been associated. It can be seen in healthy, diseased or as a part of various syndromes. Frequency of pulp stones fluctuated from 8 to 95% depending on the population studied. Our study is an attempt to know the prevalence of pulp stones in radiographs of South Karnataka population and to assess probable relations between pulp stones and gender, type of tooth, dental arch and quadrant. Comparison of our results with published documents was done and our study statistics can be considered as an added information in the field of forensic dentistry. Materials and methods: One thousand panoramic radiographs were retrospectively evaluated which included 576 females 424 males aged between 18 and 70 years. A total of 27,184 teeth were examined for the presence of pulp stones. Associations of pulp stones with sex, tooth type, dental arch and side were noted. Results: Pulp stones prevalence was 7.5% of subjects. Out of 27,184 teeth examined, 394 teeth revealed pulp stones (1.45%). Occurrences were rare in premolars (2%) but significantly higher in molars (54.6%). Pulp stones were seen more in first molars than second molars and in maxillary first molars than in mandibular first molars. Pulp stones were commonly seen in 26 to 45 years age group. Conclusion: Pulp stones may provide useful forensic infor mation when examining dental records to identify deceased persons. Dental features vary among different population and thus knowing the prevalence is significant in the forensic aspect.
