Odontomas are benign jaw tumors composed of derivatives of odontogenic epithelium and ectomesenchyme. They are divided into two groups: compound odontoma and complex odontoma. A compound odontoma is made up of many rudimentary teeth, very small, grouped in a sac whose connective wall is identical to that of the normal tooth follicle. A young patient presented for the consultation for an anterior maxillary swelling that has progressed for 4 years. The patient reported that she suffered trauma as a child. The progression of the swelling was asymptomatic. The extra oral examination was unspecific. Intraoral examination showed the presence in the vestibular mucosa of the anterior maxilla, a swelling that was hard on palpation and painless. The covering mucosa was normal in appearance. CT showed radiopaque images surrounded by a radiolucent halo in the right anterior maxillary sector around the root of 11, with a rupture of the external cortex and without invasion of the nasal cavity. Clinical and radiological data have pointed to a compound odontoma. Surgical removal of the odontomas was performed. Odontoma is one of the benign mixed epithelial-mesenchymal odontogenic tumors. The etiology of odontoma is unknown. It can appear following an old trauma. Compound odontomas are asymptomatic and discovered during routine radiographic examination. Treatment consists of surgical extraction of the odontoma alone or followed by orthodontic treatment in the event of inclusion of a tooth.

The management of demineralized dental tissues has known a huge development from the restorative approach to a more preventive approach based on non invasive procedures.
In this article , we will put the light on the resin infiltration treatment, its indications, advantages and limitations, we will deal with a detailed protocol illustrated by a clinical case of infiltration.
Last, we will discuss the outcomes and follow-ups of the issue.
Resin infiltration treatment has shown its efficiency to be a minimally invasive treatment for some of dental discolorations. It might be recommended for an aesthetical improvement of disgracious lesions.

Background/purpose: The aim of this study is to investigate the prevalence of impacted teeth and to assess the outcomes of different treatment modalities of unerupted teeth among a group of individuals with Amelogenesis Imperfecta (AI).

Materials and methods: This was a retrospective study of 27 patients’ dental records who presented to the school of Dentistry University of Monastir Tunisia from January 2005 to December 2014 and for which the diagnosis of AI was confirmed. A standardized set was used to collect information from each record.

Results: Among 27 patients, 13 were male (48.14%) and 14 were female (51.86%). The mean age was 19 ± 7.8. The prevalence of impacted teeth was 85.2% with a total of 161 impacted teeth among the 23 patients affected. Considering the location of the impacted teeth, more of them were impacted in the mandible (53%) than in the maxilla (47%). The most prevalent impacted teeth were the canines (37%), followed by premolars (30%) and molars (23%), while the prevalence of impacted incisors was substantially lower (10.5%). Only six of the 161 impacted teeth were correctly positioned in the arch, representing 3.7% of the success rate. In contrast, 89.4% of the impacted teeth failed to erupt after a duration ranged from 2 to 24 months, depending on the treatment modalities.

Conclusion: The prevalence of tooth impaction among individuals with AI was 6 times higher compared with studies involving unaffected people. The number of impacted teeth did not differ significantly between the sexes, modes of inheritance and between different types of AI. Impacted teeth were 1.13 times more likely to occur in the mandible than in the maxilla. The success rate of spontaneous eruption of impacted teeth is considered substantially lower, and it is closely related to the initial vertical position of impacted teeth, causes of impaction and treatment options.

Necrotizing gingivitis are periodontal lesions of inflammatory origin, the symptomatology of which generally includes pain, halitosis, necrosis of the interdental papillae and spontaneous gingival bleeding.
But still, general signs can also be associated with the clinical picture, such as fever, asthenia or cervical lymphadenopathy.
The objective of our work is to report two clinical cases involving two young individuals who presented to the periodontology department complaining of pain. The treatment was carried out following the conventional method, encompassing the management of the main risk factors involved in the pathology in question

Introduction: Alveolar dental trauma (TAD) are local lesions caused by the violent action of an external agent on the dental arch generally associated with partial or total dislocation of a tooth or a group of teeth . The aims of this study were to determine the frequency of alveolar-dental trauma, to describe the different clinical forms and to describe their management.

Materials and Methods: This is a six-month descriptive retrospective study carried out in the Department of Odontostomatology and Maxillofacial Surgery at Donka National Hospital.

Results / Discussion:In this study, 66% of the patients were men against 34% of women with a sex ratio (M / F) = 1.93. The 10–20 age group was the most affected, accounting for 30% of the cases, and road accidents were the main etiologies of these injuries in 55% of the cases. Pupils / students were the most affected (41%) and trauma to the maxillary incisors was the most frequently encountered in 77% of cases. The treatment was the reduction associated with restraint in the majority of cases (59%) and the results were considered good in 99% of the cases.

Conclusion: Alveolo-dental trauma presents clinical diversity, the complications and sequelae that can result are of great interest in their early management.

Introduction: Anesthesia is the abolition of spontaneous or therapeutic pain sensitivity.
The objective of this study was to assess the prevalence of failed anesthesia of the mandibular molars during endodontic treatment and to identify the causes of their failure.

Material and methods: This was a prospective descriptive study carried out at the dental center of the University of Conakry over a period of six months (from July 1 to December 31, 2016). It focused on patients received in consultation for odontalgia who benefited from anesthesia of the mandibular molars for endodontic care.
The evaluation criteria for anesthesia were based on:
- Vincent's sign (anesthesia of half of the lower lip)
- A negative response to the cold pulp sensitivity test
- The absence of pain / tenderness during the operative procedure. Pain was assessed before anesthesia and after surgery using the Analog Visual Scale (VAS).

Results: The study involved a sample of 306 patients. The male sex was more represented 52.6%, the average age is 30.44 years ± 12.45 years. The anesthetics used were Lidocaine 2% with Adrenaline 1/100 000 (14.71%), Lidocaine 3% without vasoconstrictor (76.14%), Mepivacaine 2% with Adrenaline 1/100 000 (9.15%). A failure rate of 39.2% of the anesthesia performed was recorded. The causes of anesthetic failures were mainly technical and material, 73.3% and 17.5% respectively.
Truncular spix plus supplement anesthesia was the most effective technique with a rate of 94%.

Conclusion: This study highlights the need to improve the practice of anesthesia of the mandibular molars through the continuing education of endodontic practitioners, in order to reduce failures and improve the quality of care.

Introduction: The fixed prosthesis is one of the technical acts commonly performed in a dental office. This is an epidemiological approach study and the objective is to assess the approach to the prosthesis fixed by clinicians in everyday practice in order to identify the difficulties of design and realization frequently encountered by practitioners.

Materials and Methods: This is a cross-sectional survey that targeted dental surgeons in the city of Ouagadougou practicing in private and public dental offices. A self-administrated questionnaire allowed to collect data.

Results : The majority of practitioners (72.7%) performs an average of 1.5 fixed prostheses per month. The realization of the fixed prosthesis is affordable for 54.5% of practitioners. The motivation and the requests of the patients represent 45.5%, and seem to be the sessions most worried by the clinicians the stage of preparation of the abutment teeth is difficult for 54.6% of the practitioners questioned and represented the main cause of failure of the prosthetic part.

Conclusion : Difficulties persist in mastering the prosthetic act fixed in dentistry.

Dental extractions constitute the vast majority of the activities of dental surgeons in our developing countries [1,2]. This observation, linked in part to late dental consultations, causes major aesthetic and functional damage. These include, among other things, a decrease in the masticatory coefficient and self-esteem, a disturbance of phonation and a dysfunction of the mandator apparatus with motors on the general health of the individual. toothless…) [3]. These teeth loss or edentulousness, thus constituting a real state of infirmity of the edentulous person. Their lack of prosthetic rehabilitation is nowadays a public health problem [4]. The lack of study on this problem and the increasing number of dental consultations of edentulous people at the University Hospital of Odontostomatology of Bamako (CHU-OS), reason for the present study whose objective is to take stock of the situation. the causes of this edentulousness and the dental prosthetic restorations performed.
Our study thus observed that out of 4489 subjects consulted, 1313 or 29.25% presented edentulousness. The distribution of these subjects by gender revealed 517 men or 39.4% and 796 women or 60.6%. Dental caries and their complications represent 70% of the causes of extractions leading to edentulousness.
Prevention and access to oral health care are essential elements in the conservation of the dental capital of our populations.
