[Risk behavior associated with the manipulation of dental amalgam in Senegal].

Dental amalgam is a combination of mercury, silver, tin and copper used in the treatment of the dental decays. Amalgam is used in dentistry since many years. Actually a large discussion held according to environmental pollution and risk of intoxication for the patient and the dentist himself. The aim of our survey concerning 103 dentists was to determine the quantity of mercury used in a year, to see the risks linked with the equipment and the manipulation of amalgam and to study the incoming of the trashes of amalgam. Our results showed that among the dentists: 44.66% used 250 to 500 g of mercury by year, 14.56% used their hands for insertion of amalgam in the cavities, 10.68% used their hands for condensation of amalgam in the cavities, 87.38% throw their amalgam on the trash.

[Prevalence and etiologic factors of non-carious cervical lesions. A study in a Senegalese population].

The non carious cervical lesion (NCCL) is a loss of tooth tissue at the neck of affected teeth that is unrelated to tooth decay. They are commonly encountered in clinical practice and present in a variety of forms. The purpose of this paper is to determine the prevalence of the NCCL in a Senegalese population. From 655 patients, 112 with cervical lesions were identified i.e. a global prevalence of 17.10%. The prevalence rate for abrasion was reported to be 77.70%, 12.50% for abfraction and 9.80% for erosion. Etiological factors were studied for abrasion and erosion. 54% of the patients with abrasion used their toothbrush horizontally. For erosion, only external factors were identified: consumption of acidic drinks (9 patients) or alcohol (1 patient) and professional environment (1 patient). Dentists should consider these lesions in their daily practice.

[Awareness, attitudes, and practices of secondary school students in relation to HIV/AIDS in Abidjan, Ivory Coast].

In May 2001, we conducted a descriptive transversal survey with a single data collection phase in 13 schools in Abidjan, Ivory Coast. The purpose of the study was to evaluate the awareness, attitudes, and practices of teenagers with regard to HIV/AIDS. Most respondents (66.5%) were female. Mean age was 16.32 years (range, 13 to 19 years). Most respondents stated that they had heard about AIDS and demonstrated good factual knowledge. The most frequently mentioned method of prevention was condom use (89.2%). A total of 338 (56.1%) had already experienced sexual intercourse. However most sexually active respondents stated that they did no always use condoms.

[Apical foramen position on mesio buccal root of the maxillary first molar. Study in Senegalese population].

The maxillary first molar is submitted to frequent endodontic treatment and more over, it presents the highest failure rates, often in relation with his mesio-buccal root. Several studies about failures factors showed implication of root canal anatomy often in relation with the frequency of second canal. However, other failures factors, as the foramen situation, which is very important in endodontic practice, could increase the failure rate. The aim of this study was to determine the foramen situation in Senegalese people. The results showed 63.85% of excentric foramina (83 out of 130). 86% of excentric foramina were located at 1.5mm radiology apex.

[Limit of root canal obturation by gutta percha compaction technique in single rooted teeth. Clinical data apropos of 168 canals].

After the introduction of the lateral compactage of gutta percha in endodontic clinic of OdontoStomatology Institute of Dakar in 1995; the immediate evaluation of the quality and the limit of the canal obturation due to a prospective study on 157 monoradicular teeth so be 168 canals (11 supplementary canals) has shown that 75% of canals are of type I of Vertucci and that the apical limit of security is reached within 80.25% of cases. The manual step back canal preparation (79.17%) and the technique of canal obturation by lateral compactage of gutta percha [(64.88%); Apical limit of security: 59.52%] permit to obtain a densities (95.83%) and homogeneous (79.57%) canal obturation. The indication of gutta percha compactage on monoradicular teeth (hermetic and tridimensional root canal filling) must avail to apical curved roots of lateral incisive, the use of adapted instruments in case of canines (31 mm) and apical stop cone on necrotic pulp teeth.

[Hysterectomies in tropical zones: experience of one African maternal health service. 141 cases in Burkina Faso].

We conducted a retrospective study of all hysterectomies performed in our setting over a two year period (1995-1996). The objective was double: define the indications and precise the outcome. A total of 141 cases were recorded. The main characteristics of the patients were the following: a mean age of 38 years, mean gravidity and parity of 5 and an average number of living children of 3. Hysterectomy was performed by the abdominal route in 86.52% of the cases. The main indications were: uterine rupture (39.71%), uterine myoma (25.53%), genital prolapse (19.89%) and cervix cancer (7.09%). Adnexectomy was associated in 51 cases and it was bilateral in 22 cases. The following complications occurred: 5 deaths, 8 wound abcess, 2 bladder injury, 1 ureter injury and 1 case of post-operative hemorragea.

[Oral hygiene habits and dental caries among students. Investigation of 150 students in university housing in Dakar, Senegal].

The objective of this study is to describe the oral hygiene habits and the status of the teeth decay of 150 senegalese students living in a university campus. The results showed that the toothbrush as mean of oral hygiene supplanted the traditional means such as "cure dents" or water rinse with finger. Results showed also a high rate decay (60%) but the CAO index remained low (2.04%). We founded an improvement of dental decay status with an increasing daily number of tooth brushing: we noted a decreasing dental plaque deposition rate, a decreasing decay rate and a CAO index remaining low until adult age.

[Poverty and ignorance: the cause of late consultation in odontostomatology at the University Hospital Center in Yaounde].

Coming to consult a dentist implies a toothache. Bucco-dental diseases have an insidious evolution, starting from low sound that rapidly leads to complications that are primarily manifested as pain and gingivorhage in patients. Yet there are ways of detecting these in the early stages before the stage of pain. Treating enamel decay can also be considered late if we cannot pay the price. But leaving the teeth of children decay can affect their general health throughout life. What keeps patients far from bucco-dental consultation services? Among the raisons given by 14 patients chosen at random in the Stomatology unit at CHU-Yaounde, only poverty and lack of information have drawn our attention. And to conquer this education to prevention is the solution indicated.

[Taurodontism and the pyramidal tooth at the level of the molar. Prevalence in the Senegalese population 15 to 19 years of age].

This study was done to establish the prevalence of taurodontism and pyramidal molars in Senegalese people using the criteria of SCHIFFFMAN and CHANANNEL for taurodontism and the criteria of BRABANT for pyramidal molar, the first and second molars on the panoramic radiograph of 150 consecutive 15-19 year-old Senegalese people were assessed. Results have shown that taurodontism and pyramidal molars were present in 48.6% of patients (20% of teeth). Taurodontism was present in 48% (18.8% of teeth) of patients whereas prevalence of pyramidal molar was 4.6% (1.6% of teeth). Taurodontism was alone in 91.6% of case while pyramidal molar was alone in 8.6% of case.

[A clinical study of composite restorations in anterior teeth using the Ryge criteria. Apropos of 120 cases performed at the University Hospital Center in Dakar].

In this two years retrospective study the authors determined the rate of survival composite restorations and evaluated clinically the remaining restorations by the Public Health Service (P.H.S.) criteria of Ryge. These restorations were performed by students using Heliomolar composite with scotchbond 2 adhesive dentin system. Results have shown that after two years, 98 (81.67%) out of 120 restorations were present and 51.2% were still working. Clinical evaluation of the remaining restorations needed replacement mainly because of severe color mismatch. Anatomic form and marginal adaptation were well scored after two years (score Alpha or Bravo). This study has shown that composite material is a valuable and effective technology for conservative treatment of anterior teeth in Senegal to avoid tooth extractions and prosthetic. However the knowledge about the type of composite material used must be improved and the operative procedures should be more controlled.

[Pain in intracanal treatment. A clinical study apropos of 150 cases].

This study was conducted to determine the incidence of pain during and after root canal treatment. Complete debridement and root canal preparation was performed in first visit. The frequency of pain was recorded and evaluated in 150 patients receiving root canal treatment. Results has shown that incidence of pain was 6.66% root canal preparation in vital teeth and 21% in non-vital teeth (necrosis). Post-obturation pain occurred in 18.75% for vital teeth and 13.15% non-vital teeth (necrosis).

[Delayed root canal therapy. Data on the frequency and complications].

This retrospective study of 118 teeth receiving root canal treatment was conducted to determine the frequence and complications of delayed root canal treatment. Teeth were categorised into prompt treatment group and delayed treatment group according to the length time of treatment; prompt treatment group was defined as a group where root canal treatment was achieved within a period of 4 months or less, and delayed treatments group, a group where period of treatment was greater than 4 months or where canals were never obturated. Two types of complications were studied: postobturation pain and fracture involving tooth extration. The results of this study have shown that 34.5% of treatments were delayed. In this group we found also a higher rate of fractures involving tooth extraction, but the difference was not significant. The results have also shown that disappearance of pain was the essential factors in the frequence of delayed treatment, but the dental chair breakdown had some responsability. As well as in the two groups, the first reason of extractions was fracture and not pain. These results emphasize the necessity of focusing the patient's motivation on the risk of losing the tooth.

[Importance of the number of treatment sessions in the success of root canal therapy].

Root canal therapy is usually performed in single or multiple-visit treatment. The choice of single or multiple visit depend on dentist and patient available time. In general dentistry, multiple-visit is widely chosen by dentist whereas endodontic speciality recommend single-visit. In this study we analyzed 120 root canal therapy performed by students, to determine the number of visits needed to achieve treatment from endodontic-cavity-access to root canal filling and its possible, influence in the successful rate. Results showed that globally, 60% of treatments were performed in multiple-visit. Results showed also hat 89.3% of anteriors teeth were performed in single-visit but there is a higher rate of fail: 31.78%. Nevertheless, these results do not condemn endodontic single visit therapy.

[Incidence of postoperative pain in single session root canal therapy (study in black senegalese apropos of 96 cases)].

This prospective study was conducted during a period of 30 days in 96 patients to determine the incidence of postobturation pain after single-visit root canal treatment in black Senegalese people. The canals of all teeth were hand-prepared and filled with zinc-oxide-eugenol paste by a Lentulo spiral paste filler. Patients were asked to categorize their pain according to the following criteria: No pain, Slight pain, Moderate pain and Severe pain. The data were analysed statically with chi-square test to determine the relationship, if any, between the pain experienced and sex, age, tooth type, apical level of root filling and number of treatment performed in the single-visit. Results show that eighteen patients experienced pain (18.75%); our results are ranging between 10% and 25% described in the literature. No significant correlation was found between postobturation pain and any other factor with the exception of the apical length of canal filling. Characteristics of postobturation pain after root canal treatment performed in single-visit in Senegalese people presents the same features as described in international papers, that is, pain appears early and analgesic therapy is effective.
