The aim of this study was to determine the relationship between inter canine width (ICW) and inter alar width (IAW), inter commissural width (ICoW), and inter canthal distance (ICaD) in Bantu population. Materials and Methods: It was a pilot study included all participants who were aged at least 18 years, without a history of orthodontics treatment from Prosthodontics Department, Faculty of Dental Medicine, University of Kinshasa. The Ethics committee of the National Center of Research for Dental Sciences in DR Congo approved the study protocol (CNRSB 1504.218). The participants medical records were obtained from the interview and dental examination. Nature of the study was explained with participant information sheet, and an informed consent of all participants was obtained. The inclusion criteria were no missing maxillary and mandibular teeth, no diastema, and no anterior restorations, 18 years old before enrollment in the study. The exclusion criteria were inability to meet the above requirements, pregnancy, and refusal to participate in the study. The inter-canine width (ICW), inter alar width (IAW), inter canthal distance (ICaD) and inter-commissural width (ICoW) of each participant were measured with a digital Vernier caliper (Mitutoyo, UK Ltd.,) (0.01 mm) three times and the average value was recorded. The inter canthal distance (ICaD) was measured without applying pressure by bringing the recording parts of the caliper just in contact with the medial angle. The inter alar width (IAW) was marked with a fine marked pencil on the widest outer surface of the alae of the nose on either side or width. Those two points were measured without applying pressure by bringing the recording parts of the caliper just in contact with the outer surface. The participant was told to stop breathing shortly to avoid any change in shape of the nose. The inter-commissural width (ICoW) was determined by measuring the maxillary lip vermilion from commissure to commissure without the

Background: There is paucity of literature on the determination of the root canal length of Bantu subjects in dental professional practicing in Africa and Democratic Republic of Congo in particular. Aims: The aim of the present study was to determine the root canal length of teeth of Bantu patients extracts attending the Teaching Hospital of Kinshasa University. Methods and Material: Prospective cross-sectional study was carried out in the service of Conservative Dentistry. The patients suffering with pulpitis of permanent teeth which were selected for root canal treatment during the period of January 2014 to December 2016 were included. All patients whose main root canals were inaccessible, teeth carrying prosthesis, teeth with large coronal decay, teeth having periapical periodontitis, supernumerary teeth, wisdom and primary teeth were excluded. Results: The upper canines presented some significant longer canals compared to the lower canine (23.4 ± 2.3 mm and 21.6 ± 1.8 mm). Palatal canals of the first and second molar were respectively longer as compared to the superior teeth canals (21.5 ± 1 mm, 21.3 ± 2 mm). The distal canals of the first and second molar were the longest in the mandibular arch respectively measuring 20.7 ± 2.0 mm and 21.5 ± 1.7 mm. Conclusion: Data obtained from Bantu patients show slightly shorter roots compared to some European populations, but longer than some Asian populations.

Objective:The purpose of this study was to report our experiences of thirty-five patients with mandibular odontogenic keratocyst(OKC) treated by radical resection over a 12-year period. Methods:A retrospective review of patients with OKC treated from 2003 to 2015 was carried out. Five hundred sixty-five patients were identified, of which 35 patients underwent segmental or marginal mandibulectomy. Radical resection plan was based on clinical and/or radiographic evidence of size, cortical perforation and subsequent soft tissue involvement, and history of the previous recurrence of the same lesion. Results:There were 26 OKCs in the mandibular molar-ramus, 8 in the mandibular anterior-premolar region, and 1 in the mandibular molar-ramus and anterior-molar. Twenty patients had primary OKCs and fifteen had recurrent OKCs. Segmental mandibulectomy was completed in 31 patients and 28 patients were immediately reconstructed with vascularized flap. Marginal mandibulectomy was performed in 4 patients. Functional and cosmetic outcomes of patients were satisfactory. Recurrence was found in one patient treated for marginal mandibulectomy. Conclusion:Radical resection is indicated for extensive OKC with locally aggressive features. Due to the high morbidity related to radical resection, immediate mandibular reconstruction with vascularized flap plays a key part in such treatment modality with decreasing the morbidity associated.

引用

Open Journal of Stomatology 2015年第11期5卷 251-258页

作者： nyimi bushabu fidele Feng Duan Em Kalala Kazadi Jian Guan Mantshumba Milolo Augustin Yuwen Zhou Department of Oral and Maxillofacial Surgery (Unit I) Second Affiliated Hospital of Jiamusi University Jiamusi China Stomatology and Maxillofacial Service (Unit of Periodontology Surgery) Affiliated Hospital of Kinshasa University Kinshasa DR. Congo Prosthodontics and Orthodontics Service Affiliated Hospital of Kinshasa University Kinshasa DR. Congo Department of Prosthodontics Second Affiliated Hospital of Jiamusi University Jiamusi China

Many studies have been done about the treatment of KCOT, but the recurrence rate still remains high despite the combination of surgical techniques used, associated with or without the use chemical solutions such as Carnoy’s solution or Cryosurgery. Currently, there is no consensus concerning the therapeutic choice for the KCOT. The purpose of this study was to evaluate the different treatment methods used for the management of KCOT in the Second Affiliated Hospital of Jiamusi University and the results obtained from those treatment methods. Settings and Design: Clinical study was done at the Second Affiliated Hospital of Jiamusi University. Materials and Methods: Analytical retrospective review of 63 cases treated surgically from 2009 to 2015 at the Maxillofacial and Oral Surgery Department of the Second Affiliated Hospital of Jiamusi University. All cases diagnosed as KCOT and registered in the archives were used. The level of statistical significance was set at P < 0.05. Results: Of the 63 cases, 55.56% were male and 44.44% female. The sex ratio was 1.25 in favor of male and the average age was 42 years. 81% of the lesions were located in the mandible. Of 40 cases treated by enucleation with peripheral ostectomy, curettage and electric cauterization with application of 2% iodine tincture, no recurrence was found. Of 20 cases treated by the same surgical method but without the application of 2% iodine tincture, recurrence was found in 3 cases (4.76%). 3 cases treated by resection had no recurrence. Significant relation between recurrence and type of treatment was found (P < 0.05). Conclusion: In our series, those cases that were treated by combination of surgical methods used with 2% iodine tincture showed an “improvement” in the reduction of recurrence, suggesting a future question to be examined in experimental study is to test the effectiveness of 2% iodine tincture.

Correlation between the Bizygomatic Distance and the Width of the Upper Central Incisor in the Cameroonian Melanoderma Adult

引用

Open Journal of Stomatology 2022年第10期12卷 294-304页

作者： Achoundong Makeumo Ericka Flavie Kumpanya Ntumba Pierrot Njajou Omer Agbor Michael Sekele Isouradi Bourley Jean Paul nyimi bushabu fidele Faculty of Dental Surgery University of the Mountains Bangangte Cameroon Department of Prosthodontics and Orthodontics Faculty of Dental Medicine University of Kinshasa Kinshasa Democratic Republic of the Congo Department of Oral and Maxilla-Facial Surgery Service of Oral Maxillofacial-Head and Neck Oncology Surgery Faculty of Dental Medicine University of Kinshasa Kinshasa Democratic Republic of the Congo

Bizygomatic distance is a relevant reference used to assist and to guide the choice of antero superior prosthetic teeth, especially when no information about the natural teeth was available. The aim of the present paper was to determine the distance between the canine tips from a bizygomatic distance and to estimate the width of the upper central incisor in normal-dental-facial indices of Cameroonians. Materials and methods: A cross-sectional study of 900 normal Cameroonians of both sexes was conducted. Measurements of bizygomatic distance, distance between the two upper pointers and the mesio-distal width of the upper central incisor were made with a manual and a digital caliper respectively. The equation for calculating the distance of higher canine pointers from the bizygomatic distance was DCT = 0.081 (BZD) + 26.201. The width prediction of the central incisor was obtained by the following formula: WUCI = 6.252 + 0.019 (BZD) + 0.035(DCT) + 0.062 (Reg cul) + (?0.479) sex. *** represents the cultural region of origin. Results: Female sex was represented by 56.6% against 43.30% males. The average age was 37± (32 SD) years. The average value of the bizygomatic distance was 130.23 mm, the width of the upper central incisor was 9.39 mm while the distance between the two upper canine pointers was 36.70 mm. Significant correlations between bizygomatic distance, the distance between the two canine pointers, and the width of the upper central incisor were found (P = 0.000). Conclusion: The width of the central incisor and the distance between the two upper canine pointers may be determined by the non-invasively method of the bizygomatic distance in the perspective of choosing the teeth for dental prosthesis.

Congo Unit of Oral Surgery Stomatology and Maxillofacial Service Affiliated Hospital of Kinshasa University Kinshasa DR. Congo

Aims: The objective of the current research was to determine the prevalence of supernumerary teeth and investigate its characteristic and complications in the Chinese population from the North-East Heilongjiang region. Materials and Methods: It was a descriptive and retrospective study which used registered notes and panoramic radiographs of 12,984 patients who visited the Department of Oral and Maxillofacial Surgery in the 2nd Affiliated Hospital of Jiamusi University, China between June 2011 to November 2015. Patients diagnosed with any syndrome or hereditary diseases were excluded from the study. The features of supernumerary teeth were noted and the data were analyzed using SPSS program, (version 20, Inc., Chicago, USA). The Chi-square test was used to determine the differences in the distribution of supernumerary teeth. It was tested at the 5% level of significance. Results: The prevalence was 5.2% and the most prevalent supernumerary teeth was incisor with 3.39% (n = 441). The supernumerary teeth were seen more in maxilla than mandible. The male to female ratio was 2.9:1. Specifically, higher prevalence of supernumerary teeth in male gender was statistically significant (p = 0.03). The supernumerary teeth mostly occurred in children of 5 - 10 years (62.3%), followed by young adolescent between 11 - 16 years (26.5%). Conclusion: The prevalence of supernumerary teeth was widely seen in children and young adolescent of Chinese population. The occurrence was mostly seen in maxilla than mandible and significantly higher in male than female.

Periodontitis is a prevalent destructive gum disease, characterized by loss of tissues supporting the teeth. The two main forms, chronic and aggressive have not been assessed in Kinshasa, DR Congo. Aim: The aim of this study was to investigate the Prevalence and the pattern of chronic periodontitis (CP) and aggressive periodontitis (AP) in order to improve its management. Materials and Methods: A cross sectional study of 404 subjects attending the dental services of the four hospitals of Kinshasa city, from October 2013 to April 2014 was carried out. The plaque index (PlI), bleeding on probing (BOP), probing pocket depth (PPD) and frequency of tooth brushing (FTB) were the parameters assessed. The SPSS software version 20.0 was used. Results: Out of 404 patients examined, 322 (79.7%) had chronic periodontitis versus to 44 (10.9%) of aggressive periodontitis. The female was higher than males with a sex ratio of 1.49:1 and the age group between 20 and 29 was the most represented. PPP of ≥6 mm was found in 24.6%, 5 or 5.5 mm in 27.3% and PPP of 3.5 to 4.5 mm in 48.1% of patients with periodontitis. Significant difference was found between CP and AP according to age variable, p-value < 0.001. PlI for CP was 0.97 (SD ± 0.38) while that for AP was 0.90 (SD ± 0.43). No significant differences were found between PlI, p-value = 0.47;FTB (p = 0.055) and BOP of subjects with AP and those with CP (p = 0.105). Conclusion: The two main forms of periodontitis diseases are more prevalent in patients attending dental services in Kinshasa and affect male as well as female. Age remains an essential variable to distinguish between CP and AP.
