Objectives: The term TMD refers to a group of disorders characterized by pain in the temporomandibular joint and associated structures. The aim of this study was designed to evaluate prevalence, severity and sex distribution of sign and symptoms of TMD and to evaluate their relation with anxiety and depression among the students. Material and Methods: A total of 1000 university students were enrolled in the study (550 females; 450 males), with ages ranged between 18 and 28 years. Helkimo anamnestic index (Ai) and clinical dysfunction index (Di) were used to determine symptoms and signs respectively. For the association of TMD with anxiety and depression, HAD (Hospital Anxiety and Depression) scale was used. Results showed that prevalence of one or more symptoms of TMD was 27.7%, while the prevalence of one or more signs of TMD was 64.4% which was mild in severity. Mild anamnestic symptoms (AiI) were found in 19.8% and severe symptoms (AiII) were found in 7.6%, while mild clinical sign (DiI), moderate clinical (DiII) and severe clinical sign (DiIII) were found in 49.7%, 12.2% and 2.4% respectively. Statistically there was no gender difference in these two scales. Regarding the association between TMD with anxiety and depression, 206 of the 311 students (66.2%) with TMD symptoms also had signs of anxiety and depression (P < 0.001). Conclusion: These findings confirmed that students had high prevalence of TMD which was significantly associated with anxiety and depression.

Ameloblastic fibroma (AF) is a rare tumour of mixed odontogenic origin that can occur either in mandible or maxilla but is most frequently found in the posterior region of mandible. Age of occurrence is generally between first and second decades of life. It is often mistaken for a dentigerous cyst due to presence of an impacted tooth. The diagnosis of AF usually occurs accidentally by routine radiographic examination for an impacted tooth. Histologically it consists of odontogenic ectomesenchyme resembling the dental papilla, epithelium resembling dental lamina and enamel organ without dental hard tissues. There is controversy in the literature as to whether the treatment should be conservative or a radical resection should be done. A conservative treatment strategy, such as enucleation and curettage, is usually sufficient. We describe a case of massive ameloblastic fibroma in a 5-year-old child with an unusual position in maxillary posterior region and without any impacted tooth. Surgical resection of the tumor through Weber Ferguson approach was done under GA with 2 years of follow-up without any recurrence.

Purpose: To describe a protocol for immediate placement of endosseous implant into debrided infected dentoalveolar socket. Patients and methods:A total of 21 implants were placed in 10 patients. The immediate placement protocol emphasized the meticulous debridement of the infected tissue in combination with periapical ostectomy of socket. Guided bone regeneration was accomplished to support bony healing of alveolar defects surrounding implantation site. Pre-and postsurgical antibiotic therapy was administered.Results: All implants, but one, were osseointegrated after 6 months follow-up and were functional 6 months postoperatively. One implant was mobile on exposure after 6 months and was removed.Conclusion: Successful immediate implantation in debrided infected alveolus depends on complete removal of all contaminated tissue and the controlled regeneration of alveolar defect.
