Knowledge and Practice of the Referral System under the National Health Insurance Scheme among Medical and Dental Practitioners of A Large-Accredited Facility in Kano, Nigeria.

BACKGROUND: Studies on healthcare professionals' knowledge about the National Health Insurance Scheme (NHIS) are scarce. Therefore, we assessed the knowledge and practice of the NHIS referral system among Medical and Dental practitioners in a tertiary hospital in Northwest Nigeria. METHODS: This cross-sectional study involved 242 medical and dental practitioners randomly selected from nine departments for over 6-weeks. A structured self-administered questionnaire was used to collect data. Data were analyzed using descriptive and inferential statistics. RESULTS: The respondents' mean age was 35.7±6.0 years; they were predominantly males (64.9%). Their mean overall knowledge score was 58.9±23.0%, with 66.9% of respondents having inadequate overall knowledge of the NHIS referral system. Practice department (Fishers 2 exact, P=0.0019), perceived knowledge of the referral system (ꭓ =8.169, P=0.004), and having been referred as an enrolee (ꭓ2 = 6.358, P=0.012) were associated with overall-knowledge. Obstetrics-and-Gynaecology (odds ratio[OR]=0.29, 95% confident interval [CI] [0.88-0.98]), Dental and-Maxillofacial-Surgery (OR=0.08, 95%CI[0.01-0.98]), and Otorhinolaryngology (OR=0.18, 95%CI[0.04-0.80]) respondents were less likely to have adequate overall-knowledge.Although 56.2%, 50.4%, 20.7%, and 89.7% were enrolees, had received treatment as enrolees, had been referred as enrolees and treated other enrolees, respectively, an unimpressive proportion had sighted a referral letter (64.9%) or authorization code on the letter (25.2%), referred an enrolee from their department previously (51.2%) or used the NHIS referral form to write referrals (38.8%). CONCLUSION: The overall knowledge of the NHIS referral system was inadequate. The practice of the referral system was below expectation. Therefore, training medical and dental practitioners on the NHIS referral system is necessary. Training should target those who are least likely to have adequate overall knowledge.

CONTEXTE: Les études sur les connaissances des professionnels de la santé concernant le Régime d'assurance maladie national (NHIS) sont rares. Nous avons donc évalué les connaissances et la pratique du système de référence du NHIS parmi les médecins et dentistes d'un hôpital tertiaire du Nord-Ouest du Nigeria. MÉTHODES: Cette étude transversale a impliqué 242 médecins et dentistes sélectionnés de manière aléatoire dans neuf départements pendant plus de 6 semaines. Un questionnaire structuré auto-administré a été utilisé pour recueillir des données. Les données ont été analysées à l'aide de statistiques descriptives et inférentielles. RÉSULTATS: L'âge moyen des répondants était de 35,7 ± 6,0 ans ; ils étaient principalement des hommes (64,9 %). Leur score moyen global de connaissances était de 58,9 ± 23,0 %, avec 66,9 % des répondants ayant une connaissance globale insuffisante du système de référence du NHIS. Le département de pratique (test exact de Fisher, P=0,0019), la connaissance perçue du système de référence (ꭓ 2 =8,169, P=0,004) et avoir été référé en tant qu'adhérent (ꭓ 2 = 6,358, P=0,012) étaient associés à la connaissance globale. Les répondants en obstétrique-gynécologie (rapport des cotes [OR]=0,29, intervalle de confiance à 95 % [IC] [0,88-0,98]), en chirurgie dentaire et maxillo-faciale (OR=0,08, IC à 95 % [0,01-0,98]), et en oto-rhino-laryngologie (OR=0,18, IC à 95 % [0,04-0,80]) étaient moins susceptibles d'avoir une connaissance globale adéquate. Bien que 56,2 %, 50,4 %, 20,7 % et 89,7 % étaient adhérents, avaient reçu un traitement en tant qu'adhérents, avaient été référés en tant qu'adhérents et avaient traité d'autres adhérents, respectivement, une proportion peu impressionnante avait vu une lettre de référence (64,9 %) ou un code d'autorisation sur la lettre (25,2 %), avait référé un adhérent de leur département précédemment (51,2 %) ou avait utilisé le formulaire de référence du NHIS pour écrire des références (38,8 %). CONCLUSION: La connaissance globale du système de référence du NHIS était insuffisante. La pratique du système de référence était en deçà des attentes. Par conséquent, la formation des médecins et dentistes sur le système de référence du NHIS est nécessaire. La formation devrait cibler ceux qui sont moins susceptibles d'avoir une connaissance globale adéquate.

Predictive and Relative factors of Dental Anxiety among Third Molar Disimpaction Patients in a Northern Nigerian Hospital.

INTRODUCTION: Various factors influence the expression of dental anxiety (DA) among patients. Knowledge of these factors may aid the management of mandibular third molar (M3) dis-impaction patients. AIM: The study aimed to determine the predictive and relative factors of DA among Mandibular third molar (M3) dis-impaction patients at the Aminu Kano Teaching Hospital (AKTH), Kano, Nigeria. METHODOLOGY: The study was a cross-sectional type conducted at the Oral Surgery clinic of AKTH, Kano among M3 dis-impaction patients between September 2016 and August 2017. Biodata and information on the past dental history of the participants were collected and recorded. The level of anxiety of participants was assessed with the Modified Dental Anxiety Scale (MDAS). Data were analyzed using Statistical Package for Social Sciences (SPSS) for windows (IBM SPSS statistic version 23). The significance level in the study was set at p ≤ 0.05. RESULTS: One hundred and sixteen patients comprising 62(55.2%) males and 54(44.8%) females were recruited. The sample's median age was 27 years and the majority of the participants were students (n=49,42.2%). The participants' MDAS scores ranged from 5 to 22 with a median score of 11. Females (median MDAS score of 12.50) were significantly (p<0.0001) more anxious than males (median MDAS score of 9.00). Bivariate analysis showed statistically significant differences in DA of the categories of the following independent variables - gender (p<0.0001), ethnicity (p=0.041), occupational status (p=0.044), previous surgical extraction experience (p=0.006), previous bad dental treatment experience (p<0.0001) and history of postponement of dental treatment due to anxiety(p<0.0001). Binary logistic regression analysis with these variables as independent predictors of DA showed that only gender (p=0.013) and previous surgical extraction experience (p=0.042) had statistically significant odds of predicting dental anxiety among the patients. Females had significantly higher odds of being anxious than males [adjusted odds ratio (OR) = 4.180, 95% Confidence Interval (CI)=1.359 to 12.852] and patients with previous surgical extraction experience had higher odds of being anxious than those without surgical extraction experience [adjusted OR=3.65, 95% CI=1.02 to 13.03]. CONCLUSION: The predictors of DA in the study are female gender and previous surgical extraction experience. These and other DA-related factors such as patients' occupation and previous bad dental treatment experiences should be considered preoperatively to identify and manage anxious M3 dis-impaction patients.

INTRODUCTION: Divers facteurs influencent l'expression de l'anxiété dentaire (AD) chez les patients. La connaissance de ces facteurs peut aider à la prise en charge des patients subissant l'extraction des troisièmes molaires mandibulaires (M3). OBJECTIF: L'étude visait à déterminer les facteurs prédictifs et relatifs de l'AD chez les patients subissant l'extraction des troisièmes molaires mandibulaires (M3) à l'Hôpital Universitaire Aminu Kano (AKTH) de Kano, au Nigeria. MÉTHODOLOGIE: L'étude était de type transversal et a été menée à la clinique de chirurgie buccale de l'AKTH, à Kano, auprès de patients subissant l'extraction des M3 entre septembre 2016 et août 2017. Les données biométriques et les antécédents dentaires des participants ont été recueillis et enregistrés. Le niveau d'anxiété des participants a été évalué à l'aide de l'Échelle d'Anxiété Dentaire Modifiée (MDAS). Les données ont été analysées à l'aide du logiciel Statistical Package for Social Sciences (SPSS) pour Windows (version IBM SPSS 23). Le seuil de signification de l'étude a été fixé à p ≤ 0,05. RÉSULTATS: Cent seize patients, dont 62 (55,2 %) hommes et 54 (44,8 %) femmes, ont été recrutés. L'âge médian de l'échantillon était de 27 ans et la majorité des participants étaient des étudiants (n=49, 42,2 %). Les scores MDAS des participants variaient de 5 à 22, avec un score médian de 11. Les femmes (score MDAS médian de 12,50) étaient significativement (p<0,0001) plus anxieuses que les hommes (score MDAS médian de 9,00). L'analyse bivariée a montré des différences statistiquement significatives dans l'AD des catégories des variables indépendantes suivantes : le sexe (p<0,0001), l'ethnicité (p=0,041), le statut professionnel (p=0,044), l'expérience d'extraction chirurgicale antérieure (p=0,006), l'expérience antérieure de mauvais traitement dentaire (p<0,0001) et l'histoire du report du traitement dentaire en raison de l'anxiété (p<0,0001). L'analyse de régression logistique binaire avec ces variables comme prédicteurs indépendants de l'AD a montré que seul le sexe (p=0,013) et l'expérience d'extraction chirurgicale antérieure (p=0,042) avaient des cotes de prédiction statistiquement significatives de l'anxiété dentaire chez les patients. Les femmes avaient des chances significativement plus élevées d'être anxieuses que les hommes [rapport de cotes ajusté (OR) = 4,180, intervalle de confiance à 95 % (IC) = 1,359 à 12,852] et les patients ayant déjà subi une extraction chirurgicale avaient des chances plus élevées d'être anxieux que ceux n'ayant pas d'expérience d'extraction chirurgicale [OR ajusté = 3,65, IC à 95 % = 1,02 à 13,03]. CONCLUSION: Les facteurs prédictifs de l'AD dans l'étude sont le sexe féminin et l'expérience antérieure d'extraction chirurgicale. Ces facteurs liés à l'AD et d'autres facteurs tels que l'occupation des patients et les expériences antérieures de mauvais traitement dentaire devraient être pris en compte en préopératoire pour identifier et prendre en charge les patients anxieux subissant l'extraction des M3.

Impact of COVID-19 on Management and Outcome of Cervicofacial Infections in a Maxillofacial Centre.

INTRODUCTION: Cervicofacial infections (CFI) are life-threatening and constitute some of the common emergencies seen by the oral and maxillofacial surgeon on a regular basis. The COVID-19 pandemic resulted in reduced human activities for most of 2020 including the first worldwide lockdown. At the height of the pandemic, it was expected that the number of patients presenting with cervicofacial infections would drop as with most health conditions. The purpose of this study was to determine the impact of COVID-19 on the management and outcome of cervicofacial infections in a tertiary maxillofacial institution. PATIENTS AND METHODS: A retrospective analysis of patients who presented at the Maxillofacial clinic with cervicofacial infections and were subsequently admitted into the ward during the lockdown (2020) was compared with those of the previous year (2019) and the year after (2021). RESULTS: The total number of patients seen and admitted with cervicofacial infections in 2020 was 39(31.2%) which was lower than that seen the preceding year 48(38.4%) but higher than 38(30.4%) of the year after. 116 patients were treated while nine patients left hospital without treatment. All patients presented with extensive cervicofacial infections, involving more than three fascial spaces and were treated using parenteral antibiotics with surgical incision and drainage under local anesthesia. There were more deaths in 2020 (n=10) than in the preceding year (n=8) and the year after (n=7). CONCLUSION: A high percentage of CFI was admitted during COVID-19 period compared to the previous and following years. Involvement of multiple fascial spaces was also noted.

INTRODUCTION: Les infections cervico-faciales (ICF) mettent la vie en danger et constituent certaines des urgences les plus courantes que rencontre régulièrement le chirurgien buccal et maxillo-facial. La pandémie de COVID-19 a entraîné une réduction des activités humaines pendant la majeure partie de l'année 2020, y compris le premier verrouillage mondial. Au plus fort de la pandémie, on s'attendait à ce que le nombre de patients présentant des infections cervico-faciales diminue comme pour la plupart des problèmes de santé. Le but de cette étude était de déterminer l'impact de COVID-19 sur la gestion et le résultat des infections cervicofaciales dans une institution tertiaire maxillo-faciale. PATIENTS ET MÉTHODES: Une analyse rétrospective des patients qui se sont présentés à la clinique maxillo-faciale avec des infections cervico-faciales et ont ensuite été admis dans le service pendant le lockdown (2020) a été comparée à celles de l'année précédente (2019) et de l'année suivante (2021). RÉSULTATS: Le nombre total de patients vus et admis pour des infections cervico-faciales en 2020 était de 39 (31,2 %), ce qui était inférieur à celui de l'année précédente (48 (38,4 %)) mais supérieur à celui de l'année suivante (38 (30,4 %)). 116 ont été traités tandis que neuf patients ont quitté l'hôpital sans traitement. Tous les patients présentaient des infections cervico-faciales étendues, impliquant plus de trois espaces fasciaux et ont été traités à l'aide d'antibiotiques parentéraux, avec incision chirurgicale et drainage sous anesthésie locale. Il y a eu plus de décès en 2020 (n=10) que l'année précédente (n=8) et l'année suivante (n=7). CONCLUSION: Bien qu'un pourcentage élevé de FCI ait été admis pendant la période COVI-19 par rapport aux années précédentes et suivantes, l'implication de multiples espaces fasciaux a également été constatée.

Neurogenic Tumors of the Oral and Maxillofacial Region in a Nigerian Population.

BACKGROUND: Neurogenic tumors constitute a group of true and pseudo-tumors arising from tissues derived from embryonic neural crest cells. They are rare in the maxillofacial region. OBJECTIVES: To analyze the demographic, clinical presentation and histopathological spectrum of neurogenic tumors of the oral and maxillofacial region seen over a 28-year period. MATERIAL AND METHODS: A retrospective observational study which highlighted the demographic, clinical presentation and histopathological spectrum of neurogenic tumors of the oral and maxillofacial region seen between 1992 and 2020 in a tertiary health facility. RESULTS: A total of 56 patients were studied with a male to female ratio of 1:1.5 and the age spanned from 1 to 72 years (mean of 26.2 ± 17.9 yrs). The commonly involved sites were the cheek (n = 9; 16.0%), scalp (n = 9; 16.0%) and eyelid (n = 6; 10.7%). Histopathological data showed a preponderance (n = 38; 67.9%) of neurofibroma over other types of neurogenic tumors. The treatment modalities used were surgical (n = 37; 94.9%) and oncological (n = 2; 5.1%). Complications noted were recurrence in 2 patients and hypertrophic scar formation in 1 patient. CONCLUSION: In this environment, orofacial neurogenic tumors appear to be common in the second decade of life, affect the extraoral structures mainly and the most common form is neurofibroma.

CONTEXTE: Les tumeurs neurogènes constituent un groupe de tumeurs vraies et pseudo-tumorales provenant des tissus dérivés des cellules de la crête neurale embryonnaire. Elles sont rares dans la région maxillo-faciale. OBJECTIFS: Analyser la démographie, la présentation clinique et le spectre histopathologique des tumeurs neurogènes de la région orale et maxillo-faciale observées sur une période de 28 ans. MATÉRIEL ET MÉTHODES: Une étude d'observation rétrospective qui a mis en évidence la démographie, la présentation clinique et le spectre histopathologique des tumeurs neurogènes de la région orale et maxillo-faciale observées entre 1992 et 2020 dans un établissement de santé tertiaire. RÉSULTATS: 56 patients au total ont été étudiés, avec un rapport hommes/femmes de 1:1,5 et un âge compris entre 1 et 72 ans (moyenne de 26,2 ± 17,9 ans). Les sites les plus fréquemment touchés étaient la joue (n=9; 16,0%), le cuir chevelu (n=9 ; 16,0%) et la paupière (n=6 ; 10,7%). Les données histopathologiques ont montré une prépondérance (n=38 ; 67,9%) de neurofibromes par rapport aux autres types de tumeurs neurogènes. Les modalités de traitement utilisées étaient chirurgicales (n=37; 94,9%) et oncologiques (n=2; 5,1%). Les complications notées ont été la récidive chez 2 patients et la formation d'une cicatrice hypertrophique chez 1 patient. CONCLUSION: Dans cet environnement, les tumeurs neurogènes orofaciales semblent être fréquentes dans la deuxième décennie de vie, affectent principalement les structures extraorales et la forme la plus fréquente est le neurofibrome.

Giant Ameloblastoma and the Risk of Recurrence: Experiences from a Tertiary Hospital.

BACKGROUND: Ameloblastoma is an aggressive tumor of odontogenic epithelium that grows slowly with propensity for bone expansion. Sometimes it may grow to very large sizes also known as giant ameloblastoma (GA) which may affect function and even pose a threat to life. OBJECTIVE: To present the pattern of presentation of GAs seen in a tertiary centre in Northern Nigeria. PATIENTS AND METHODS: A retrospective study of patients seen with GA at the Oral and Maxillofacial Clinic of a tertiary health facility of Northern Nigeria between January 2006 to December 2019. All patients with complete documentation in the folder, theatre register and histopathologic records were recruited for the study. Data were analyzed using SPSS version 23. RESULTS: GAs accounted for 30.2% (48) of all the ameloblastomas operated during the period with a male dominance of 62.5% (30), giving a ratio of 1.7:1(M:F). The age range was between 12 and 65 years with a mean age of 35.04years (±14.5) and the mandible was the most affected jaw compared to the maxilla (12.5%). Lesions with lowest and highest weight were found on the mandible (77g and 1640g respectively). The treatment most given was mandibulectomy (unspecified) with 20.0% followed by Rt and Lt mandibulectomies with 14.0% each. CONCLUSION: GA was found to account for 30.2% of all lesions seen within the period under review, while the mandible was the most affected jaw bone.

CONTEXTE: L'améloblastome est une tumeur agressive d'épithélium odontogène qui se développe lentement avec une propension à expansion osseuse. Parfois, il peut atteindre de très grandes tailles aussiconnu sous le nom d'améloblastome géant (GA) qui peut affecter la function et constituent même une menace pour la vie. OBJECTIF: Présenter le modèle de présentation des AGvu dans un centre tertiaire dans le nord du Nigeria. PATIENTS ET METHODES: Une étude rétrospective des patients vu avec GA à la clinique orale et maxillo-faciale d'un tertiaire établissement de santé du nord du Nigéria entre janvier 2006 et Décembre 2019. Tous les patients avec une documentation complète dans le dossier, le registre des théâtres et les dossiers histopathologiques étaient recruté pour l'étude. Les données ont été analysées à l'aide de la version SPSS23. RÉSULTATS: Les AG représentaient 30.2 % (48) de tous les améloblastomes opérés pendant la période avec un home dominance de 62.5% (30), ce qui donne un rapport de 1.7:1 (M:F).la fourchette se situait entre 12 et 65 ans avec un âge moyen de 35.04 ans(±14.5) et la mandibule était la mâchoire la plus touchée comparéeau maxillaire (12.5 %). Lésions de poids le plus faible et le plus élevé ont été trouvés sur la mandibule (77g et 1640g respectivement). Le traitement le plus administré était la mandibulectomie (non spécifiée) avec 20.0 %, suivis des mandibulectomies Rt et Lt avec 14.0 % chacun. CONCLUSION: L'AG représentait 30.2 % de tous les lésions observées au cours de la période considérée, tandis que la mandibule était l'os de la mâchoire le plus touché.

The effect of dental anxiety on surgical time of mandibular third molar disimpaction.

BACKGROUND: Dental treatment of anxious patients induces stress due to the patients' expectation of pain. This may prolong treatment due to such patients' inability to cooperate during treatment. AIM: The aim of the study was to determine the effect of dental anxiety on surgical time of mandibular third molar (M3) disimpactions at a Nigerian hospital. SUBJECTS AND METHODS: A prospective study was conducted at the Oral Surgery clinic of Aminu Kano Teaching Hospital, Kano, between October 2016 and September 2017 to assess the effect of dental anxiety on surgical time of M3 disimpactions using the Modified Dental Anxiety Scale (MDAS). The Patients' biodata, clinical and M3 radiologic data were recorded. Surgical durations were also recorded. Data were analyzed with Statistical Package for Social Sciences for Windows (IBM statistics 23 software). RESULTS: One hundred and sixteen subjects (64 males, 52 females) were studied. Forty-two subjects (36.2%) were mildly anxious, 67 (57.8%) were moderately anxious, and 7 (6.0%) were highly anxious. The females were more anxious and the overall surgical time (OST) of disimpaction correlated with the anxiety levels of the subjects. The OST increased by approximately 0.8 min with every unit rise in the anxiety score. Other factors that affected OST in the study were M3 depth, type of impaction, and root curvature. CONCLUSION: The patients' dental anxiety increased the surgical time of M3 disimpactions. Clinicians should consider the patients' anxiety among the factors that affect the surgical time of M3 disimpactions. Verbally soothing anxious patients and administering anxiolytic when necessary, may help to reduce the patients' anxiety, and hence, prevent surgical time prolongation.

Descriptive Epidemiology of Odontogenic Tumors in Nigeria: An African Oral Pathology Research Consortium Multicenter Study.

BACKGROUND: Many studies have investigated the burden of odontogenic tumor (OT) in Nigeria; however, the true burden and prevalence of these lesions are not known because these studies are based on a center/region. AIMS: Hence, the aim of this study is to evaluate the true burden of OTs in Nigeria, using a multicenter approach. MATERIALS AND METHODS: This is a 10-year retrospective cross-sectional study of OT seen in eight tertiary health institutions in different geographic locations in Nigeria. RESULTS: A total of 990 cases were included in this study. The highest prevalence of OT was in the third decade of life (n = 274, 27.7%). Most lesions were benign (n = 961, 97.1%), with a slight male preponderance; and the mandible was the commonest site (n = 814, 82.2%). There were a significant association between the diagnosed OTs and the age group and site (P = 0.002 and 0.031, respectively). CONCLUSION: OTs showed a slightly higher preponderance in males, occurring mostly in the third decade. Benign lesions were frequent and ameloblastoma was the commonest OT. Variations exist in the occurrence of OTs from the different geographic locations in Nigeria. This study essentially sheds a broader light on the clinicopathological distribution of OTs across Nigeria, using a large multicenter approach.

ORO-FACIAL FASCIAL SPACE INFECTION IN A PAEDIATRIC GAMBIAN POPULATION: A REVIEW OF 93 CASES.

BACKGROUND: Oro-facial fascial space infection is known to be a clinical presentation of neglected dental care. The proportion of children with dental sepsis has also been known to increase markedly with caries experience. Such fascial space infection in the paediatric age group is known to progress rapidly within a short period and is thus potentially more fatal than in the adult population. AIM: This study aimed to document and evaluate the pattern of oro-facial fascial space infection amongst paediatric Gambian population. PATIENTS AND METHODS: The study was a 4-year descriptive retrospective survey of all patients with oro-facial fascial space infection seen and managed at the dental unit of the polyclinic attached to the Edward Francis Small Teaching Hospital in Banjul, The Gambia from May 2015 to April 2019. The information collated were patients' sociodemographic data as well as clinical features related to their medical and dental condition. The extracted data were analyzed using Statistical Package for Social Sciences (SPSS) version 15.0 (SPSS Inc, Chicago, IL). Absolute numbers and simple percentages were used to describe categorical variables. Quantitative variables were described using mean (with standard deviation), median and range. Categorical variables were compared using chi square test and numeric variables compared using student t-test. Differences were considered significant if p<0.05. RESULTS: A total of 322 patients with oro-facial fascial space infection were managed within the period of the study out of whom 93 patients that met the inclusion criteria were studied. Their ages ranged from 3 months to 16 years, with a mean age of 8.5(SD2.1) years. There were 54 males and 39 females with a gender (M: F) ratio of 1.4: 1. All the patients presented with painful facial swelling and fever. Eighty-one (87.1%) had a history of toothache. The median number of fascial space involvement was 1 space; the submandibular space was involved unilaterally in 43 (46.2%) and bilaterally in 8 patients (8.6%). Eighty-one (87.1%) were odontogenic in origin and 12 (12.9%) were non-odontogenic. Seventy-two (88.89%) of odontogenic cases involved posterior teeth and 45 (62.5%) of these were the first permanent molars. Incision and decompression and teeth extraction were done for all the odontogenic cases. Staphylococci and/or streptococci were cultured from six patients. All the patients had inpatient treatment with a combination of intravenous amoxicillin, metronidazole and gentamicin treatment. Mortality rate was 5.4% (5 out of 93) and the mean age of patients who died, 3.0 (SD0.3) years, was significantly lower than that of those who survived, 8.3 (SD1.4) years, (p<0.0001). CONCLUSION: The commonest symptoms of oro-facial fascial space infection in the Gambian paediatric population were fever, facial swelling and toothache. Most of the infections were odontogenic and affected most commonly the submandibular space. Posterior teeth were more commonly involved than the anterior, with the first permanent molar being the most commonly affected tooth. Incision and decompression were performed in all odontogenic cases, with extraction of all culprit teeth. All patients had in-patient treatment with intravenous amoxicillin, metronidazole and gentamicin. The mortality rate was 5.4%. The burden of dental caries with its complications is huge in the paediatric population of the Gambia. Training of dental surgeons and specialists and their auxiliaries with advocacy on the need for regular dental checkup for children, as well as prompt attention to dental diseases will help to reduce this scourge.

REASONS FOR LOSS OF THE PERMANENT TEETH IN PATIENTS IN KANO, NORTH WESTERN NIGERIA.

BACKGROUND: Loss of permanent dentition is often of great concern to patients, apart from the aesthetic consequences in the anterior region of the mouth, such loss has no natural form of replacement. AIM: To determine the pattern of tooth loss among patients attending the Dental Clinic at a Nigerian teaching hospital. MATERIAL AND METHODS: The case files of patients who attended the Dental Clinic of Aminu Kano Teaching Hospital, Kano between January and December 2012 with one or more missing tooth were retrospectively analyzed. The information collected included age, gender, educational level, residential area, missing tooth/teeth and reasons for the loss. The data were analyzed using SPSS version 13.0 (Chicago, Illinois). A p-value of less than 0.05 was considered significant. RESULTS: A total of 1100 missing teeth were recorded involving 960 patients within the period of one year. Males comprises 520(54.2%) and females 440(45.8%). The most predominant age group was the 21-30 years with a mean of 29.53 +12.41 years and this comprised 48.2% of the cases. Caries related extractions (65.6%) were the most common cause of tooth loss followed by periodontal disease in 13.1% of cases and symptomatic impacted tooth in 9.8%. Gender affects the etiology of tooth loss was significant with males having more tooth loss (X2=52.93, df=6, P=0.001). There was a significant association between age and the pattern of tooth loss with tooth loss due to periodontal diseases occurring in the older age groups (X2=1071.67, p=0.001). CONCLUSION: Dental caries and periodontal diseases still remain the main causative factors for tooth loss in this environment, more common in men and rural dwellers.

Prospective study of the quality of life after treatment of mandibular fractures.

Health-related quality of life (QoL) has become increasingly important, but few studies have dealt with that of patients who have been treated for mandibular fractures. Our aim was to assess this. Patients with mandibular fractures (n=148) were studied prospectively and QoL after treatment was assessed using the General Oral Health Assessment Index (GOHAI). The male-female ratio was 8.3:1 and their ages ranged from 14 to 70 years. QoL after treatment of the fractures declined initially (on the first postoperative day) but thereafter improved steadily. There was no significant difference between the mean QoL of those treated by closed, and those treated with open, reduction. Limitations in the options of food to eat, and difficulty in chewing and swallowing, were identified as their most important concerns in the early postoperative period. The improvement in QoL after the first postoperative day was similar however the patients were treated.

EXPERIENCE WITH miniplate osteosynthesis in THE MANAGEMENT OF mandibular fractures IN NORTHWEST NIGERIA.

BACKGROUND: Fractures of the mandible are the commonest facial fractures and various treatment modalities exist like wire osteosynthesis and the use of miniplates and screw with most of the industrially developed world leaning towards the use of miniplates in the treatment of these fractures. The use has however been limited in developing countries (including Nigeria) mostly due to the cost of the plates and screws. AIM AND OBJECTIVES: To identify the versatility of miniplates in the treatment of mandibular fractures at a tertiary care centre in a developing country. METHODS: All Subjects aged 16 years and above in whom mandibular fractures were diagnosed were recruited over a two year period. Patients were treated under general anesthesia using either the miniplates and screws or wire osteosynthesis while some patients had both miniplates and maxillo-maxillary fixation. RESULTS: A total of 94 patients were recruited for the study of which 89.4% were males while the age group 16 to 25 years constituted the majority. Though 29.8% of the study population was involved in business, only 9.6 % were professional motorcyclists. Motorcycle-related road traffic crashes constituted the commonest aetiologic agent with 41.5%, while combination fractures were the commonest fracture types seen in 54.3% of the study participants. Of the 94 patients, 77.7% had treatment of mandibular fractures by open reduction and immobilization with mini plates, while 7.4% had mini plates with Maxillo-maxillary fixation and 14.9% had wire osteosynthesis only. The site of fracture was significantly associated with the treatment modality (p= 0.02). CONCLUSION: This study showed that the choice of fixation appliances in mandibular fractures was influenced by the number of fractures and the multiplicity of fracture sites. Miniplates offered functionally stable fixation with minimum complications.

Management of Odontogenic Fibromyxoma in Pediatric Nigerian Patients: A Review of 8 Cases.

Odontogenic fibromyxoma (OFM) is a benign, locally invasive and aggressive nonmetastasizing neoplasm of jaw bones. They are considered relatively rare and known to be derived from embryonic mesenchymal elements of dental origin. Treatment of OFM depends on the size of the lesion and on its nature and behavior. Varying treatment modalities ranging from curettage to radical excision have been documented. Aim; This paper is a review of management of 8 pediatric patients with histologically diagnosed OFM at a Nigerian tertiary health care facility. This was a retrospective study of all patients aged 15 years and below who presented to the Oral and Maxillofacial Surgery Clinic of Aminu Kano Teaching Hospital, Kano, over a 5-year period (January 2008 to December 2012), with a histologic diagnosis of OFM. The information obtained included patients' demographics, as well as their clinical characteristics such as the anatomical site and side of lesions. Other information collated included presenting features, the onset of symptoms, type of treatment carried out, as well as treatment outcome. The data were analyzed and the results presented as frequencies and percentages. Among the 8 patients with OFM, more males (n = 5/8; 62.5%) were affected than females (n = 3/8; 37.5%). The mandible (n = 5/8; 62.5%) was the most frequent site of occurrence, and the anterior mandible was the most favored location (n = 4/8; 50%). Seven patients had excision of the lesion with peripheral ostectomy of the underlying bone while only one patient had a bone resection. These patients have been followed up for at least 1 year, and no recurrence was observed throughout the follow-up period. OFM causes gross facial disfigurement and may result in the destruction of the entire jaw bone; the impact of which may be grave for a growing child. Prompt surgical intervention and follow-up have proven to be adequate management protocol.
