Purpose: The purpose of the present study was to develop a novel selective medium (OVSM) and useful identification method for oral Veillonella species, to assess the prevalence of this species using the selective medium, and to investigate whether the monitoring of oral Veillonella species levels is useful as a clinical indicator for the diagnosis of halitosis. Methods: To examine bacterial populations in the oral cavity, a novel selective medium (OVSM) and multiplex PCR method were developed for isolating and identifying oral Veillonella species. OVSM consists of tryptic soy agar, sheep blood, sodium lactate, vancomycin, and oxacillin. Results: Oral Veillonella species grew well on OVSM. Oral Veillonella species accounted for 5.4% and 27.2%, respectively, of all bacteria in the tongue biofilm samples of healthy and halitosis subjects. Oral Veillonella species produced larger amounts of volatile sulfur compounds than other representative oral bacteria. Conclusion: These results indicate that monitoring the levels of these organisms is useful as a clinical indicator for the diagnosis of halitosis.

Introduction: Temporomandibular joint ankylosis (TMJA) is a fusion of joint surfaces by fibrous or bone tissue and the resulting limitation of mouth opening. The objectives of this study were to determine the frequency of TMJA, describe the clinical aspects and assess management. Materials and Method: It was a retrospective study that was carried out in the Department of Odontostomatology and Maxillofacial Surgery of Donka National Hospital for a period of 5 years (January 2016 to December 2020). Included were all records of inpatients and managed cases of TMJA during the study period. Sociodemographic, clinical and therapeutic variables were analyzed. Results: During the study 13 TMJA cases were collected with the frequency of 0.47%. The age group 1 9 was the most affected (61.54%) with extremes of 4 and 28 years. Men were the most concerned (53.87%). Restriction of mouth opening was the main reason for consultation (69.23%). The etiologies of ankylosis were dominated by infection including cellulitis of dental origin (53.85%) followed by facial trauma (30.77%). Arthroplasty was the most commonly used technique (73%), two cases of recurrence were noted (15.38%). Conclusion: TMJA affects mainly children and the etiology is dominated by cellulite of dental origin hence the interest of sensitization of the population for early management of oral diseases.

Context: Prosthetic treatments for partial edentulism aim to restore or improve oral functions such as mastication, phonation and aesthetics. They have an impact on nutritional status, general health and quality of life. Objectives: To determine the frequency and determinants of wearing dental prostheses in partial edentulous Congolese adults as well as the reasons of prosthetic non-rehabilitation. Methods: Partial edentulous patients attending five medical-dental centers in Kinshasa were included in this cross-sectional study. Each patient completed a questionnaire and underwent a clinical examination. Chi-square test was used for searching associations between variables and logistic regression for determinants. The significance level was 0.05. Results: Three hundred partial edentulous patients with an average age of 40.3 ± 15.9 years participated in this study. 11% (CI: 7.5% and 14.5%) of partial edentulous Congolese adults wore a dental prosthesis. Age was the independent determinant of denture wearing. Young adults (under 30) were 5 times more likely to not wear dentures than older people. The absence of discomfort was the major reason for not prosthetic rehabilitation (32%) followed by finances (30%). Conclusion: Very few partially edentulous Congolese adults were prosthetics wearer. Age was the only determinant.

The high frequency of dental extractions creates a high demand for prosthetic rehabilitation. Therefore, this study aimed to describe the profile of consumers of prosthetic care at the Institute of Odontology and Stomatology in Dakar. It was a descriptive and retrospective study of patients who had been consulted at the prosthetic clinic of the Institute of Odontology and Stomatology of Dakar. Data were collected from medical records from 09 November 2019 to 09 June 2020. The tools used to collect and process the information were the Sphinx software and the Excel spreadsheet. Out of the 101 patient records, 51% were male and 48% belonged to the age group of 18 to 39 years. Nearly 38.61% of the patients lived less than 5 km from the health care facility and 70.3% of the res-pondents had a monthly income of fewer than 100,000 FCFA. Clinically, 96% of patients came for functional reasons, 78.2% for aesthetic reasons, and partial edentulism was the most frequent diagnosis (96%). Chi-square tests were performed to find a dependency or non-dependency relationship between diagnosis and age, but also between income and treatment cost. In sum, age and diagnosis were independent of each other, just as patient income was not related to treatment cost. Proximity to health facilities, income, and cost of treatment are factors that influence accessibility to oral health care. It is important to integrate the profile of the consumer of care into global management.

Introduction: The endodontic management of necrotic permanent immature teeth is a challenge for the practitioner. These teeth are treated by apexification. However, because of the complications associated with this treatment, researchers have developed other therapies. Currently, a new technique called pulp revascularization has emerged. This technique allows the continuation of root completion thanks to a healthy tissue newly formed at the intra root canal level. Material and method: A literature search of articles dealing with pulp revascularization of immature permanent teeth was conducted using two types of search strategy, a literature search using keywords on databases and then a manual “bottom-up” search of references of previously identified articles. Results: 112 articles were identified based on inclusion and exclusion criteria. Discussion: This work showed that pulp revascularization is a new therapy that aims to restart root development on an immature permanent tooth. It is based on the principle of tissue engineering and uses the differentiation potential of stem cells. Conclusion: Currently, the literature values revascularization as it allows root development, sidewall thickening, apical closure and a decrease in periapical lesion and ensures a good sealing. Clinical and radiographic success rates appear to be encouraging, except that factors influencing treatment must be taken into consideration.
