Abstract
Cervical cancer (CC) is a multifactorial disease of which human papillomavirus (HPV) is the main etiological agent. Despite cervical Pap smear screening and anti‑HPV vaccination, CC remains a major public health issue. Identification of specific gene expression signatures in the blood could allow better insight into the immune response of CC and could provide valuable information for the development of novel biomarkers. The present study performed a transcriptomic analysis of peripheral blood mononuclear cells (PBMCs) from Senegalese patients with CC (n=31), low‑grade cervical intraepithelial neoplasia (CIN1; n=27) and from healthy control (CTR) subjects (n=29). Individuals in the CIN1 and CTR groups exhibited similar patterns in gene expression. A total of 182 genes were revealed to be differentially expressed in patients with CC compared with individuals in the CIN1 and CTR groups. The IL1R2, IL18R1, MMP9 and FKBP5 genes were the most upregulated, whereas the T‑cell receptor α gene TRA was the most downregulated in the CC group compared with in the CIN1 and CTR groups. The pathway enrichment analysis of the differentially expressed genes revealed pathways directly and indirectly linked to inflammation. To the best of our knowledge, the present study is the first large transcriptomic study on CC performed using PBMCs from African women; the results revealed the involvement of genes and pathways related to inflammation, most notably the IL‑1 pathway, and the involvement of downregulation of the T‑cell receptor α, a key component of the immune response. Several of the stated genes have already been reported in other cancer studies as putative blood biomarkers, thus reinforcing the requirement for deeper investigation. These findings may aid in the development of innovative clinical biomarkers for CC prevention and should be further replicated in other populations.

Abstract
BACKGROUND Helicobacter pylori plays a significant role in gastric disease. The aim of the present pilot study was to evaluate the prevalence of H. pylori detected by real-time polymerase chain reaction (real-time PCR) in the sub-gingival plaque of chronic periodontitis patients and to determine periodontopathogens profile of positive sites at H. pylori. METHODOLOGY 109 subgingival samples collected from 17 subjects with chronic periodontitis were studied. The DNA was extracted from the oral samples and analyzed for the presence of H. pylori by real-time PCR (LightCycler) using 16S rRNA#120 primers which targeted the 16S rRNA gene. DNA from H. pylori DSM 4867 was used as a positive control. Seven bacteria implicated in chronic periodontitis were selected to explore the presence of these periodontopathic species in the oral positive sites for H. pylori. RESULTS 16 of 109 samples (14.7%) were positives of H. pylori. All the positives sites were also positives to Fusobacterium nucleatum and Eikenella corrodens, 62.5% to Porphyromonas gingivalis, 31.25% to Treponema denticola, 25% to Prevotella intermedia, 12.5% to Aggregatibacter actinomycetemcomitans and 6.25% to Tannerella forsythia. CONCLUSIONS H. pylori may be present in the subgingival plaque samples of patients with chronic periodontitis who are resident in a developing country. F. nucleatum and E. corrodens could coaggregate with H. pylori in the subgingival dental plaque.

Abstract
Hormonal contraception is based on the use of synthetic hormones containing variable doses of oestrogen and progesterone making it possible to avoid pregnancy in a temporary and reversible way. The objective of this study is to evaluate the periodontal status of a sample of Senegalese women under hormonal contraceptive. One hundred women using contraception since at least 6 month were paired on the age, the socio-economic profile and oral hygiene with a control group. Oral hygiene (plaque index (PI) of Silness and Löe), the inflammation (gingival index (GI) of Löe and Silness), probing depth and clinical attachment loss were recorded. With equal hygiene, the scores of the gingival index were significantly higher among women under contraceptive (p < 0.001). Inflammation was significantly more marked for the women who used contraception in injectable form compared to the control group (p < 0.001). Probing depth (3.01 +/- 0.04) and clinical attachment loss (3.19 +/- 0.08) were significantly more important among women under contraceptive (p < 0.001). The women under contraceptive seem to set up a group at risk for developing a periodontal disease, it is thus necessary to systematise periodontal appraisal before and during contraceptive use period.

Abstract
PURPOSE to confirm or infirm structural modification of oral mycosis at the summit after fifteen days of wearing removable resin partial dentures. METHODS our study took place at the health center of Rufisque in Senegal from January to July 1998, involved fourteen patients divided into two groups according to sex: seven males and seven females who came for removable resin partial dentures. The macroscopic examination was conducted through to inspection and touching of mycosis at the level of toothless summit before the wearing of the denture. A biopsy was conducted on each patient before and after the wearing of the resin dentures. Tissue reaction was appreciated qualitatively through morphological analysis. RESULTS Before the wearing of the removable resin partial dentures 92.9% of patients had epithelial hyperplasia; 7.1% epithelial hypoplasia and 85.7% keratosis at the level of the chorion the number of collagen fibbers (28.6% discrete, 50% moderate, 21.4% important), fibroblasts (35.7% discrete; 42.9% moderate ; 21.4% important), inflammatory cells (71.4% discrete; 28.6% moderate; 0% important) and for blood vessels (64% discrete; 35.70% moderate; 0% important) after fifteen days of wearing partial denture. After fifteen days of the wearing removable resin partial dentures: 85.7% of patients had epithelial hyperplasia; 14.3% normal epithelial and 100% de keratosis at the level of the chorion the number of collagen fibbers (14.3% discrete; 21.4% moderate; 64.3% important), fibroblasts (42.9% discrete; 42.90% moderate; 14.3% important), inflammatory cells (50% discrete, 35.7% moderate: 14.3% important), blood vessels (43% discrete; 28.6% moderate; 28.6% important). CONCLUSION Biopsies of the summit are reliable contribution; they provide precise information on the quality of tissue supporting resin partial dentures. This tissues may seem healthy appearance (inspection and touching) but show sign of suffering at this anatomy-pathological examination.

Abstract
Sickle cell anaemia is an inherited disorder of haemoglobin synthesis leading to haemolytic anaemia. It touches more than 50 million people in the world and 10% of the population in Senegal. Only the homozygous form is symptomatic and appears by painful crises of vaso-occlusive type. There is a lack of works carried out or published in Senegal about potential link between periodontal conditions and sickle-cell anaemia. The main objective of this study is to assess the gingival conditions in Senegalese children and adolescents homozygous sickle cell anaemic. Secondary, the gingival state is correlated with oral hygiene and rate of reticulocytes to determine their relationship. Fifty homozygous attending the Albert Royer Paediatric Hospital of Dakar and unscathed of other systemic pathologies, were examined. The patients are old between 3 and 16 years with an average age 9.4 years +/- 3.8. The gingival state is assessed by measurement of the gingival index (GI) and index of sulculary bleeding (SBI). Partial correlation is performed between the two indexes and average of reticulocytes. The gingival index mean is 1.7 +/- 0.6 and 66% of the patients present a severe inflammation, which is more frequent in the age bracket from 3 to 12 years. The SBI mean is 1 +/- 1.1 and 68% of the patients present gingival bleeding, which is moderate to severe in 18%, with a greater frequency in the age bracket from 13 to 16 years. Strong correlation is found between plaque index, GI and SBI. Damage of gingival state seems not to be linked to the high average of reticulocytes controlling for oral hygiene. Children and adolescent homozygous have an inflammatory periodontium associated to poor oral hygiene, which highlights their needs in periodontal treatments. Early tracking and preventive treatment of periodontal diseases during systematic oral visits must be required.

Abstract
AIM To evaluate the performance of bond strength and the compatibility of Prime &Bond NT self etching adhesive resins without activator on dentin surface with dual composite resin LuxaCore, and verify the contribution of a coactivator. MATERIAL AND METHODS twenty-four human teeth without decay, molars or pre-molar are used. The dental crowning is cut with diamond disc mounted on a hand piece; the roof surface is flattened and well humidified. Each tooth is embedded in cold self-etching resin (Plexil Excil). Samples are divided into two groups of 12. in the first group, self-etching Prime &Bond NT resin adhesive without activator is supplied on the flat mesial dentin roots, then dual cure composite resin LuxaCore) is bonded. The second group was subject to the same treatment but with addition of co-activator the Prime &Bond NT self-etching adhesive resin. Debonding was achieved with Universal testing machine and mean shear bond strengths were determined for each test group. The data were subjected to ANOVA (p < 0001). RESULT Bond strength obtained with self-etching Prime &Bond NT without activator is 10.635 MPa. With addition of activator it is 15.185 MPa CONCLUSION supplementing with an activator has significantly improved bonding strength.

Abstract
The authors try to appreciate the perception by student and non student population of dental care throughout fear of dentist, pain and dentist-patient relationship, also the patient preventive attitude. Results show more fear of the dentist by students and expressed pain. Dental cares are expensive according both students and non students but seem to be comfortable. Dentist-patient relationship is more appreciated at the Odontologic Institute which form future dentists and 80 per cent of patients consult for prophylactics care against 29 at the medico-social centre of the university. Dental care accessibility in developing country is a real problem and rate of dental diseases cannot be taken down without support of information and communication waves.

Abstract
INTRODUCTION The strong prevalence of schistosomiasis in the school population is correlated with underperformance in educational outcomes in Senegal. The geoclimatic conditions and bad socio-economic conditions facilitate transmission of these infections. This study was to define t he prevalence of these infections in sites throughout the country in school age children. MATERIALS AND METHODS This study was undertaken from November 2002 to January 2003 and included 63 schools; (n=2245) for an effectif of 30 000 pupils, means 7.4%. These pupils underwent urine examination for schistosomiasis in children with hematuria using millipore filtration method. RESULTS The results of the study are: overall there were 364 cases (16%). Prevalence rates: Tambacounda 27.8%, Bakel 21.5%, Kédougou 21.8%, Matam 13%, Podor 22.5%, Dagana 28.3%, and Saint-Louis 0%. This study demonstrates a high prevalence of parasites in school age children. Notably there is unique infection patterns in each village and this data will help direct public health interventions. CONCLUSION These results show a high rate prevalence of urinary schistosomiasis in school population in these departments. It explains the underperformance in educational outcomes in these a reas.

Abstract
Most of parodontal diseases have a bacterial aetiology. Their episodic and asynchronic evolution differs from site to site. The "in situs" antimicrobian used in the parodontal bags reduces the systemic administration. Various antibiotics or antiseptics slow liberation systems were experimented. Two patients suffering from advanced parodontitis were treated after radicular scraping by subgingival irrigation with a syringe filled with chlorhexidine. Each patient presented at last four parodontal bags more or less six millimetres (6 mm) deep. The following clinical parameters were noted: Patch index, bleeding index, bag depth. A bacteriological analysis was realized at the beginning and of the treatment. Controls were made at D60. Results showed a significant improvement of clinical parameters. It seems that the chlorhexidine irrigation improves the parodontal treatment efficiency.

Abstract
Among several factors in preterm low birth weight, we can find pre-conceptional causes and others depending on pregnant women's behaviour. In 1996 a scientific team composed by periodontists, gynaecologists and epidemiologists found that 18% of preterm low birth weight in 250,000 babies are due to periodontal infection. In our survey we used 113 pregnant women in gynaecological clinic in university hospital. By using Community Periodontal Index Treatment Needs (CPITN) in pregnant woman and by weighting babies as soon as accouchement done. In spite of percentage of preterm low birth weight, we registered 33.9% babies of normal birth weight with mother's CPITN under 1.

Abstract
Senegal, in middlewest Africa, has an estimated area of 197,000 km2 with a population of about 8.3 million of whom 45 per cent are less than 14-years of age. Apart from densely populated areas around the capital, Dakar, and other large towns, the population is scattered sparsely in rural areas. In the absence of any recent and representative oral health data, two cross-sectional studies on caries prevalence were conducted in 1989 and 1994 respectively to assess and compare the caries status among 12-year-old schoolchildren living in the urban and rural areas of Senegal. The results of the study are presented in this paper.

Abstract
Gingival mucus in an older patient is the site of the slowing-down of the cellular turnover, of a lessening of metabolic activity and of keratinisation. The resistance to mechanical attacks and bacteria lessens thus its potential for repair. Thus one notes a worsening state of parodontal complaints during old age. By means of a study carried out at the Clinique de Parodontie of the Institut d'Odonto-Stomatologie in Dakar, we propose to attempt to see if the presence of gingival retraction can be linked with parodontal senescence by means of observing 318 patients.

Abstract
Therapeutic acts often surgically practised in the dental office can lead to the transmission of infectious diseases such as A.I.D.S. To prevent this, the authors propose guideline base acts for antisepsis and asepsis. In conclusion, the authors exhort for an integration of these antiseptic acts in the efficient working of the dental office for an effective prevention of these infectious diseases in the area.
