Objective: The aim of this study was to determine the average values of width of the upper central incisor (WUCI) in Congolese Bantu and compare them to those of Caucasians and Asiatic. Material and Methods: It was a prospective cross-sectional study carried out at the Université de Kinshasa on the Congolese Bantu, Department of Dental Medicine, from March 2020 to March 2021. A The each Results: The Average Width of the UCI was 8.74 mm ± 0.56. The average width of the right Upper Central incisor (RUCI) and the left UCI (LUCI) was 8.71 mm ± 0.57 and 8.77 mm ± 0.56, respectively. The average width of the RUCI and LUCI was not the same for men and women (p 0.001). A significant difference was observed between the average of the RUCI and the 18 - 28 and 40 - 50 age group (p = 0.056) as well as for the average LUCI (p = 0.085). The width average of UCI between the Congolese Bantu with those of Caucasians and Asians was significantly different (p = 0.000 and p = 0.009). Conclusion: The average width of the RUCI and LUCI was different among sex and age group. The average width of UCI of the Congolese Bantu is different from that of Caucasians and Asians.

Background: Head and neck cellulitis of dental origin are polymicrobial bacterial infections involving the cellulo-adipose spaces of the face and neck. The objective of this work was to describe the epidemiological and clinical profile of patients with head and neck cellulitis. Methods: This was a cross-sectional study conducted from 1 January to 30 June 2020. All patients consulting for cervico-facial cellulitis of dental origin in 2 university hospitals in Ouagadougou were included in the study. The usual parameters of descriptive statistics were estimated for each variable. Results: Two hundred and ninety-two cases (184 men and 108 women), aged 3 to 85 years were collected. The 25 - 35 years old were the most affected (33%). Decay was the leading dental cause (95.6%). The delay in consultation was included within 7 days in 74.66% of cases. Ninety-one-point forty-four percent of patients had poor oral hygiene. Diffuse cellulitis was the most common (64.04%) and peri-mandibular regions were the most invaded (42.81%). Conclusion: The frequencies observed in our study allow us to conclude that cervicofacial cellulitis of dental origin is still frequent and affects a young and disadvantaged population.

Introduction: The management of nasolabial-palatal clefts in precarious environments is one of the topics most addressed by many humanitarian missions, especially in Africa and Asia. The aim of our study was to propose a humanitarian and not expensive care to the patients presenting with facial clefts during the fairgrounds in disadvantaged areas. Patients and Method: We carried out a prospective study on 32 patients who were operated with very limited means during the mobile clinics inside Togo during the year 2013. These patients were followed over a period of one year after their surgery. Included in our series were native patients with facial clefts, who had no means of managing their condition, and who therefore needed humanitarian support. We have reported the clinical history of some patients to illustrate our results. Results: Our study included 32 children, including 15 boys and 17 girls, with a sex ratio of around 1. The average age of patients was 5 years, with extremes of 6 months and 13 years. We performed 13 clefts (including 12 unilateral clefts and 1 bilateral cleft), 17 clefts palate (including 12 unilateral clefts and 5 bilateral clefts), and 2 velar clefts. We described the clinical history of a few patients in this humanitarian setting and showed the surgical results obtained.

Background: Cervicofacial cellulitis is a severe infection and is responsible for a major disruption of host homeostasis. The aim of this work was to describe the haematological and biochemical variations of cervico-facial cellulitis. Methods: This was a cross-sectional study conducted from 1 January to 31 December 2020. All patients hospitalized for cervico-facial cellulitis of dental origin were included in the study. The usual parameters of descriptive statistics were estimated for each variable. Results: Our sample consisted of 166 patients. The average age of patients with cervicofacial cellulitis in our study was 39.9 ± 15.39 years. Red blood cell count was low in 55.5% of patients and hyperleukocytosis was noted in 89.16% of patients. Platelets were normal in 43.14% of patients and 78.43% of patients had a low haematocrit (haemodilution). Anemia was noted in 64.7% of patients. In addition, 61.0% of patients had elevated uricemia and 31.17% had elevated creatinemia. Conclusion: Cellulitis is still a common condition in less privileged environments. Its diagnosis can be guided by clinical and biological findings. Consistent education of the population on oral health, and the control of biological disorders that result from it, are sufficient to greatly reduce its prevalence and the appearance of complicated forms.

Background: The relationship between pregnancy and periodontal health had well documented in the literature. Of many studies of periodontal diseases in the Democratic Republic of Congo, no study had evaluated these diseases in pregnant women during Prenatal Consultation (PC). This study aimed to describe the occurrence and clinical profile of periodontal diseases in pregnant women admitted to the PC at the General Military Hospital of BOBILA. Materials and Methods: It is a cross-sectional and analytical study of pregnant women admitted to the PC from August to December 31, 2018, at the General Reference Military Hospital of BOBILA/Kinshasa City. The data were collected through a survey combined with the stomatological interview. Sociodemographic data, clinical and periodontal indices included Oral Hygiene Index Simplified (OHI-S), Bleeding on Probing (BOP), and Periodontal Disease Index (PDI) were assessed. The statistical analyses were carried out using the SPSS version 20.0 software. The Chi-square tests, Student t-test were used to determine differences in the distribution of variables, and the odd Ratio with a confidence interval (IC) at 95% was used to estimate the degree of association. The results were significant at p < 0.05. Results: Of the 105 pregnant women received at the PC, 83 were included in this study. The age group between 20 - 29 was the most represented, with a predominance of stay-at-home mothers (75.9%) and married cases (73.4%), they had an average economic status (56.6%) and a secondary education level (63.8%). Gingival bleeding (44.6%) was the main complaint of the pregnant. Gestational age was a significant factor associated with gum bleeding (p < 0.005). Most of the pregnant had poor oral hygiene, localized gravidities (69.6%) during the third semester. Conclusion: A significant proportion of women had experienced periodontal diseases during the pregnancy period, mostly in the third trimester, and was associated with a gestational age of pregnant women.

Purpose: To establish a simple and accurate photodynamic diagnosis (PDD) method for oral squamous cell carcinoma (OSCC). Methods: OSCC cell lines HSC-2, HSC-3, HSC-4, and Sa3, and normal human oral keratinocytes (HOK) were used. First, we examined the amount of cells needed to detect differences in fluorescence intensities for PDD. OSCC cell lines were adjusted to concentrations of 1 × 104 (104), 1 × 105 (105), and 1 × 106 (106) cells/ml. The experimental groups comprised a group with 5-aminolevulinic acid (5-ALA (+)), and a group without 5-ALA (5-ALA (-)). For each OSCC cell line, 100 μl of each concentration of cells of the 5-ALA groups was seeded onto fluorescence plates, and fluorescence intensity was measured at 60-min intervals for 240 min. Results are expressed as the ratio of fluorescence intensity in 5-ALA (+) to 5-ALA (-). As cells at the concentration of 106 cells/ml provided the clearest results, fluorescence intensities of all cell lines were measured using this concentration at 20-min intervals for 700 min using the same methods. Results: The 5-ALA (+) to (-) ratio increased in a cell concentration-dependent manner at 240 min; the ratio was highest with 106 cells/ml and lowest with 104 cells/ml. With 106 cells/ml in the 5-ALA (+) group, fluorescence intensity increased in a metabolic time-dependent manner; the increase was highest in HSC-2 cells, followed by HSC-4 cells, HSC-3 cells, Sa3 cells, and HOK. Fluorescence intensity was significantly enhanced after 40 min in HSC-2, HSC-3, and HSC-4 cells, after 60 min in Sa3 cells, and after 100 min in HOK compared to the 5-ALA (-) group (P < 0.05). Moreover, fluorescence intensity was significantly increased in OSCC cell lines compared to HOK after 40 min. Conclusion: Early detection of OSCC is possible by screening only microplate reader measurements of fluorescence intensity for PDD.

Introduction: Orbital floor fractures are a significant pathology among maxillofacial injuries. They can cause oculomotor, sensory, and sometimes esthetic disorders. The goal of this study was to determine the epidemiological profile of orbital floor fractures and show their clinical and therapeutic approach in Lome. Patients and method: This was a descriptive retrospective study of orbital floor fractures collected in the ENT and maxillofacial surgery department of Sylvanus Olympio University Hospital in Lome over 8 years (January 1, 2011 to December 31, 2018). Results: We reviewed 63 cases of orbital floor fractures out of 552 cases of facial trauma. According to the inclusion and non-inclusion criteria, we retained 51 cases. The hospital frequency of orbital floor fractures was 9.24% of facial fractures. The average age of the patients was 35 ± 10.34 years. Males were predominant (ratio = 7.5). The main etiology was road accidents (92.16%). Ophthalmological signs were dominated by vertical diplopia (31.37%), limited eye movement (25.49%), and enophthalmia (29.41%). The sensory sign was dominated by suborbital hypoesthesia (13.73%). Surgical treatment was performed in 86.27% of patients. The average intervention time was 17.84 ± 12.69 days after the trauma. The main approach was the subciliary route (65.91%). The surgical procedures consisted of muscle and fat removal (20.45%) and orbital floor repair by mesh plate (50%). The average length of hospitalization was 9.63 ± 5.23 days. Surgical site infection was the main postoperative complication observed in 3.92% of patients. The main sequelae were diplopia (4.55%), suborbital hypoesthesia (4.55%), and enophthalmos (4.55%). Conclusion: Orbital floor fractures are mainly due to road accidents. Management must be multidisciplinary and adequate in order to avoid irreversible functional and/or morphological sequelae. Their prevention consists of effective combat of road accidents.

They can cause oculomotor, sensory, and sometimes esthetic disorders. The goal of this study was to determine the epidemiological profile of orbital floor fractures and show their clinical and therapeutic approach in Lome. Patients and method: This was a descriptive retrospective study of orbital floor fractures collected in the ENT and maxillofacial surgery department of Sylvanus Olympio University Hospital in Lome over 8 years (January 1, 2011 to December 31, 2018). Results: We reviewed 63 cases of orbital floor fractures out of 552 cases of facial trauma. According to the inclusion and non-inclusion criteria, we retained 51 cases. The hospital frequency of orbital floor fractures was 9.24% of facial fractures. The average age of the patients was 35 ± 10.34 years. Males were predominant (ratio = 7.5). The main etiology was road accidents (92.16%). Ophthalmological signs were dominated by vertical diplopia (31.37%), limited eye movement (25.49%), and enophthalmia (29.41%). The sensory sign was dominated by suborbital hypoesthesia (13.73%). Surgical treatment was performed in 86.27% of patients. The average intervention time was 17.84 ± 12.69 days after the trauma. The main approach was the subciliary route (65.91%). The surgical procedures consisted of muscle and fat removal (20.45%) and orbital floor repair by mesh plate (50%).

Introduction: The aim of this study was to determine whether there was a significant difference in shear bond strength between metal and ceramic brackets when exposed to acidic dietary components (beverages) and to observe the chromogenic potential of each in vitro. Methods: Metal and clear orthodontic brackets were placed on extracted maxillary second premolars and exposed to select beverages three times daily for four weeks. Shade was taken using a colorimeter device at seven intervals and the shear bond strength of each bracket was recorded. Results: There was a variable change in tooth shade with respect to the various beverages in which they were submerged. Coffee and Dr. Pepper had the most pronounced change, whereas Red Bull and water produced little to none, respectively. Compared to controls, brackets submerged in coffee had the greatest reduction in shear bond strength, followed by Dr. Pepper, then Red Bull. Overall, clear brackets showed higher shear bond strength than metal brackets. Conclusion: Acidic dietary components have a negative effect on the shear bond strength of orthodontic brackets, and more pigmented beverages have a higher chromogenic staining potential.
