Oral cancer is a growing public health problem, it is increasing worldwide since it is the sixth most common cancer overall. The highest rates of oral cancer occur in the most disadvantaged sections of the population. Early detection and screening have been shown to be effective in reducing mortality and morbidity caused by oral cancers. To ensure early detection of oral cancer measures such as mass screening or screening of high-risk group population; reducing the delay from patients´ side by creating awareness about signs and symptoms of oral cancer. Today, no national population-based screening programs for oral cancer have been implemented yet. The objectives of this project are to evaluate and educate Tunisian Dentists as well as health professionals to perform oral screening and early detection of suspicious oral lesions in order to reduce morbidity and mortality associated with oral cancer.

-Introduction:After radicular and follicular cysts, odontogenic keratocysts are the third most common cyst of the jaws. They can be unique or multiple when included in basal cell nevus syndrome. The odontogenic keratocyst is known for its high recurrence rate and local aggressiveness. It has been classified into two histologic variants: orthokeratinized or parakeratinized. The aim of this report is to highlight the clinical and radiological characteristics, the histopathological features, as well as the risk factors for recurrence of odontogenic keratocysts. Case report: Two clinical cases of odontogenic keratocysts with different histologic features are reported. Discussion: Radiological and histological features, localization, extension and evolutionary aspect of the lesion are risk factors for recurrence, and therefore have an impact on the treatment of keratocysts. Through critical analysis of the first case report, the authors identify therapeutic errors to avoid, particularly when histologic confirmation of the lesion has been obtained. Résumé -Introduction :Après le kyste périapical et le kyste folliculaire, le kératokyste odontogène est le troisième plus fréquent des kystes des maxillaires. Il peut être unique ou multiple s'il est associé à la naevomatose baso-cellulaire. Le kératokyste a un risque élevé de récurrence et une agressivité locale. Il a été classé en deux variétés histologiques : orthokératinisé ou parakératinisé. Observation : Deux cas de kératokystes odontogènes sont décrits sur un plan clinique, radiologique et histopathologique. Discussion : Le type histologique, l'image radiologique, la localisation, l'extension et l'aspect évolutif de la lésion sont des facteurs de risque de récidive. Ces facteurs doivent être pris en compte dans la décision thérapeutique. À travers une analyse critique du premier cas, les auteurs mettent en exergue les erreurs thérapeutiques à éviter, notamment lorsqu'une confirmation histologique a été obtenue.

A cutaneous sinus tract of dental origin may easily be misdiagnosed and incorrectly treated. This paper reported a case of a 20‐year‐old male patient referred for a productive cutaneous sinus tract misdiagnosed by medical doctors for more than 4 years. The clinical and radiographic examinations confirmed the odontogenic origin related to a mandibular first right molar presenting an infected radicular cyst. Surgical treatment was performed leading to a significant healing of the sinus tract.

Implant placement in patient with history of bisphosphonate therapy is still controversial due to the risks of osteointegration failure and Biphosphonate related osteonecrosis of the jaws. Very few cases are reported. This paper aimed to report the success at 3 years follow up of 4 implants placed in a female patient with history of breast cancer and zoledronate infu-sions ( twice yearly for 2 years).

Fanconi anemia (FA) is a rare autosomal recessive disorder characterized by multiple congenital abnormalities, bone marrow failure, and higher susceptibility to malignancies, especially to head and neck carcinomas. Only few reports about the oral manifestations of FA are available. The main reported oral conditions associated with FA are microdontia and advanced periodontitis. The aim of this paper was to report a case of a 10-year-old patient with FA presenting severe spontaneous gingival bleeding, as well as to discuss the role of the dentist in the management and treatment of this condition.
