Abstract
BACKGROUND Mandibular fractures are universal in distribution, but its etiologies and presentation patterns differ from one country to another because of varying socioeconomic, cultural and geographical factors. We analyzed the etiological factors and presentation patterns of mandibular fractures in a tertiary hospital at Nigeria's second largest city. METHODS Patients with isolated mandibular fractures at Aminu Kano Teaching Hospital, Kano were prospectively reviewed over a 12-months period. Patients' demographic information and fracture characteristics (etiology, site, pattern and number of fracture) were recorded and analyzed. RESULTS One hundred and forty-eight patients presented with 180 mandibular fractures. There were eight-fold higher men with mandibular fractures than women (M: F =8.3:1) with highest incidence in third decade of life. Road traffic accidents (84.46%) was the major etiology while iatrogenic fracture (0.68%) was found in one patient. Mandibular body was the most fractured site (41.11%) with parasymphyseal and angle regions accounting for 27.78% and 23.89% of total recorded fractures respectively. CONCLUSIONS Mandibular fractures in Kano, Northwest Nigeria occurred predominantly in men in the third decade and are mostly caused by road traffic accidents. The majority of these fractures involved the mandibular body.

Abstract
Background Lingual nerve injury is a known complication of mandibular third molar (M3M) surgery, and retraction of the lingual flap is reported to reduce the incidence of this complication. However, there is no global consensus on the routine retraction of lingual flap. Aim The aim of the study was to assess the perception and practice of lingual flap retraction amongst oral and maxillofacial surgeons in Nigeria. Materials and Methods This cross-sectional national survey was conducted amongst 122 oral and maxillofacial surgeons in Nigeria from January 2023 to March 2023 using a validated, structured, self-administered questionnaire. The questionnaire had three sections and 14-item questions. Section A consists of the sociodemographic questions, Section B comprises questions on perception towards lingual flap retraction, whereas Section C consists of questions on the practice of lingual flap retraction. These questionnaires were deployed as an online survey and as hard copies. Both qualitative and quantitative data were analysed. A critical probability level (P < 0.05) was used as the cut-off level for statistical significance. Results Most of the participants (47.6%) belong to the age group of 31-40 years. The male-to-female ratio was 6:1. Only 12 (9.8%) participants had a positive perception towards routine lingual flap retractions following M3M surgery. Perception of lingual flap retraction was found not to be associated with the demographic variables of the participants (P > 0.05). A total of 95 participants (77.9%) did not raise nor retract the lingual flap during lower third molar surgery. The rate of practice of lingual flap retraction during third molar surgery was not influenced by any of the factors studied (P > 0.05). Conclusion The majority of oral and maxillofacial surgeons in Nigeria do not agree that routine retraction of the lingual flap is necessary to reduce lingual nerve injury and majority, too, do not practice this in their management of impacted lower third molar.

Abstract
Study Design This is a multi-centre retrospective study. Objective To determine the prevalence of blindness and pattern of facial trauma associated with blindness among Nigerians. Methods A multi-centre retrospective study of all patients with facial trauma resulting in blindness, that were co-managed by maxillofacial surgeons and ophthalmologists in 4 Nigerian public tertiary hospitals between January 2010 and December 2019 was undertaken. Data was analysed by IBM SPSS Statistics (version 21.0 for windows, IBM© Inc, Chicago, IL). Results Of 2070 patients who presented with major facial injuries during the study period, 61 eyes of 56 (2.7%) patients were blind. Blindness was bilateral and unilateral in 5 (8.9%) and 51 (92.1%) patients, respectively. The mean age (SD) at presentation was 36.2 (16.6) years, and 47 (83.9%) of these patients were males. Road traffic accident (n = 27; 48%) was the commonest mechanism of facial trauma, the cheek (n = 18; 40.9%) was the commonest site of associated soft tissue injury and zygomatic complex fracture (n = 19; 24.1%) was the commonest related fracture. Globe rupture (n = 34; 55.7%) was the leading cause of blindness. Enucleation (n = 7; 13.2%) and evisceration (n = 22; 41.5%) were performed on 29 eyes of which 12 (41.4%) patients had ocular prosthesis post-operatively. Conclusions Blindness was recorded in 2.7% of Nigerians with facial trauma. The commonest mechanism of trauma and cause of blindness in at least one eye were road traffic accident and globe rupture, respectively. Eye removal surgery was necessary in about half of the blind eyes.

Abstract
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.

Alkaline Phosphatase Profile of Patients with Fibro-Osseous Lesions. IRANIAN JOURNAL OF OTORHINOLARYNGOLOGY 2022; 34:311-318. [PMID: 36474492 PMCID: PMC9709386 DOI: 10.22038/ijorl.2022.63776.3185] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Subscribe] [Scholar Register] [Received: 02/27/2022] [Accepted: 09/19/2022] [Indexed: 01/25/2023]
Abstract
INTRODUCTION Although some studies on craniofacial fibro-osseous lesions have assayed serum alkaline phosphatase levels of affected patients, the findings of these reports are often inconclusive. The aim of this study was to determine the association between the serum ALP levels of individuals with craniofacial fibro-osseous lesions (CFOLs) and treatment outcome. MATERIALS AND METHODS Consecutive patients who presented at the Ahmadu Bello University Teaching Hospital, Zaria from May, 2016 to December, 2017 with lesions histologically diagnosed as CFOLs. The Speight and Carlos' (2006) classification of CFOLs was adopted, and the serum ALP level of patients and their age- and- gender matched apparently healthy controls were measured at presentation, and repeated at the 3rd and 6th post-operative months for subjects only. Treatment outcomes were assessed 6 months post treatment. RESULTS Fifty cases of CFOLs were recorded with a male preponderance, while fibrous dysplasia was the most prevalent lesion, and the maxilla was the most affected jaw (62%). Only 11 subjects had elevated serum ALP levels at presentation, and the mean serum ALP level of subjects with CFOLs was higher (341.2 ± 198.1 IU/L) than that of their age-and gender-matched controls (190.7 ± 110.2 IU/L). With the exception of subjects whose lesions recurred, there was a decrease in the mean serum ALP levels of subjects by the 3rd (245 ± 170.2 IU/L) and 6th (240.5 ± 172.7 IU/L) months post-treatment. Thirty three subjects had elimination of lesions, while three cases each recurred or developed morbidity. CONCLUSION The treatment outcomes of patients with fibrous dysplasia appear to be associated with their serum ALP level. Therefore, serial serum ALP level monitoring suggested in the management of patients with fibrous dysplasia of the craniofacial region.

Abstract
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.

Expectations, Experiences and Perceptions of Oral and Maxillofacial Surgery Residents to Training in Nigeria. EUROPEAN JOURNAL OF DENTAL EDUCATION : OFFICIAL JOURNAL OF THE ASSOCIATION FOR DENTAL EDUCATION IN EUROPE 2022; 26:248-253. [PMID: 33982385 DOI: 10.1111/eje.12693] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2020] [Revised: 01/25/2021] [Accepted: 04/30/2021] [Indexed: 06/12/2023]
Abstract
PURPOSE How surgical residents fare during their training could enhance job satisfaction and fulfilment post-training. But there is paucity of literature on the experiences of oral and maxillofacial surgery (OMS) trainees during residency training. The aim of this study was to report the expectations, experiences and perceptions of OMS residents towards training in Nigeria. METHODS Cross-sectional study of OMS residents in accredited Nigerian training institutions was conducted between September and December, 2017. Study tool was adapted from that used for general surgery residents in the United States. Results were analysed using Microsoft Excel for Windows 10. RESULTS Sixty-eight of seventy-three questionnaires were returned (response rate was 93%). More respondents were males (86.8%) than females (13.2%). 44.1% of all respondents were aged 35-39 years. Senior residents (n=31, 45.6%) were more than those in the junior cadre. The most important reason for choosing OMS residency training was for knowledge (72.1%) followed by the prospect of better pay (8.8%). Most residents believed their opinions were important (66.7%) and looked forward to their daily work (72.1%) but were dissatisfied with the didactic teaching aspect by consultants (57.3%) and felt the hours and stress of working were straining their family life, respectively (91.0% and 76.7%). CONCLUSION Most OMS residents were happy and expected to gain knowledge from the training. However, some were dissatisfied with the training duration and level of didactic teaching by consultants and the impact of residency training on family life. There is need to improve didactic teaching and ensure adequate work/family balance for better OMS residency training in Nigeria.

Abstract
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.

Abstract
INTRODUCTION Odontogenic fibroma (OF) is a rare benign tumor of mesenchymal odontogenic tissue with variable global incidence. Two variants comprising extraosseous /peripheral (POF) and intraosseous /central (COF) have been identified based on the anatomical origin of the tumor. OF isslow growing, and often asymptomatic with characteristic radiographic appearance of a unilocular or multilocular cyst frequently associated with unerupted or displaced teeth while histologically, varying amount of inactive odontogenic epithelium embedded in a mature relatively dense collagenous stroma is diagnostic. The absence of odontogenic epithelium does not exclude the diagnosis of odontogenic fibroma. CASE REPORT A 15 months old female presented with 3 months history of left lower jaw swelling which showed aggressive growth following incisional biopsy. Parents said lesion was noticed for the first time as pinpoint on the submandibular area and was too small to warrant any worries. Initial radiograph revealed absence of bony involvement but the second showed evidence of bony involvement. An impression of soft tissue sarcoma was made and incisional biopsy was sent for pathological diagnosis which revealed peripheral odontogenic fibroma. The rapidity of growth following incisional biopsy bellied a benign lesion. CONCLUSION An aggressive odontogenic fibroma with multifocal points in a 15months old girl.

Abstract
Objective: During pregnancy, changes occur in the oral environment with gingivitis predominating. The development of odontogenic infections within the period of pregnancy may endanger the life of the mother as well as that of her unborn baby. Materials and methods: A retrospective observational study of cases of cervicofacial infection in women during pregnancy was conducted at the oral and maxillofacial surgery clinic of a northern Nigerian tertiary health care center from January 2006 to June 2018. Results: Seventy women were managed for cervicofacial infection during the period reviewed, out of which 20 women (28.6%) presented during pregnancy. Their mean age was 33.8 ± 9.35 years with a range of 20 to 55 years. The 30-39 years age bracket had the highest frequency (40%) and the mean duration of pregnancy at presentation was 24.9 ± 11.12 weeks with a range between 10 to 36 weeks. Majority (n=15, 75.0%) presented in the 3rd trimester. At presentation, the frequently involved fascial space was unilateral submandibular space (n=10; 50.0%), All the patients had incision/drainage/decompression on the dental chair under local anesthesia (2% lidocaine with 1:80,000 adrenaline). The mean length of hospital stay was 13.9 ± 6.2 days with a range of 6 to 26 days. The mortality rate was 15% (n=3 cases). Conclusion: There is a need for oral health evaluation in pregnant women during ante-natal visits to prevent these complications. Oral health education should also form part of teachings received by women both in the ante-natal and postnatal clinics.

Abstract
Aim: The aim of the study was to report the etiology, pattern, and spectrum of ocular injuries in patients with maxillofacial injuries seen at a tertiary care hospital in northern Nigeria. Patients and Methods: This is a retrospective evaluation of the etiology, spectrum, and treatment of ocular injures seen in patients with midfacial fractures, who presented at Ahmadu Bello University Teaching Hospital, Shika-Zaria, Nigeria, a tertiary care hospital in northern Nigeria. Cases were seen at the oral and maxillofacial clinic for those presenting with midfacial fractures, whereas those presenting with ocular injuries due to midfacial injuries were referred from the ophthalmology department. Data were collected on their demographics, etiology of injuries, body part(s) involved, and treatment. Results: A total of 256 patients had midfacial injuries during the period, of which 219 patients had 357 associated ocular injuries. The age range was between 3 and 76 years. There were more males (83.8%) than females (16.2%), giving a male-to-female ratio of 5.2:1; the 21–30 years' age bracket was most frequently affected (38.4%). The predominant etiology of injuries was road traffic accidents (RTAs) (90.1%), followed by assault (4.9%). Zygomatic complex fractures (38.6%) and orbital wall fractures (24.7%) were the common midfacial injuries. There were 357 ocular injuries, giving a patient: injury ratio of 1:1.6, with subconjunctival hemorrhage (32.5%) and ruptured globe (20.0%) being common. Treatments performed were reduction and immobilization of midfacial fractures plus evisceration (32.0%), followed by reduction and immobilization of fractures alone (23.9%) and reduction and immobilization plus grafting of soft tissues (21.2%). Conclusion: Ocular injuries are quite common in patients with midfacial injuries, with a ratio of 1.6:1. RTA was the most common etiology, with zygomatic complex fractures as the most common midfacial injury. Subconjunctival hemorrhage was the most common ocular injury manifestation, with young adults (21–30 years of age) being most affected. Treatment often involved reduction and immobilization of midface fractures with evisceration and grafting of ocular tissues.

Abstract
BACKGROUND Orofacial clefts are the most common orofacial congenital malformations and dental anomalies are more prevalent in such individuals. OBJECTIVES To assess the frequency and distribution of orofacial clefts and associated dental anomalies in a group of patients with orofacial clefts. MATERIALS AND METHODS A retrospective study involving the assessment of dental records of orofacial cleft patients who had their surgical repair at a health institution between March, 2013 and December, 2019. Their socio demographic characteristics, type of cleft, type of dental anomaly observed, teeth affected and number of teeth affected were reviewed. The records were analysed using IBM SPSS, version 21 and Chi square test to compare differences between groups while the level of significance was set at P < 0.05. RESULTS A total number of 62 records were studied. More than half were males 36(58.1%) with a mean age of 16 (+ 15.6) years. The most frequent type of cleft was unilateral cleft lip (64.5%), majority had their cleft (65.3%) and dental anomalies (80.7%) on the left side of the face (p=0.001). The most frequently recorded dental anomaly was hypodontia/missing teeth (62.9%) and there was a significant relationship between tooth rotations and cleft lip. CONCLUSION Unilateral left cleft lip was the most prevalent. Hypodontia/missing teeth was the most common dental anomaly among the study group. Tooth rotations were seen more in patients with cleft of the lip (CL). Individuals with orofacial cleft requires holistic health care so as to improve their quality of life.

Abstract
Background: Epidemiological studies despite their limitations provide information that is useful for the formulation of effective and efficient injury prevention strategies. Aim: The aim is to carry out epidemiology study of mandibular fracture in a Nigerian population. Setting: Department of Oral and Maxillofacial Surgery, Ahmadu Bello University Teaching Hospital, Shika-Zaria, Nigeria. Materials and Methods: A retrospective observational study was carried out at the Ahmadu Bello University Teaching Hospital, Shika-Zaria. Data retrieved from patients’ case notes and operating records were subjected to statistical analysis involving frequencies (count, percent), measures of central tendency (mean), and measures of dispersion (standard deviation) using Statistical Package for Social Sciences (SPSS) version 16 (SPSS Inc., Chicago, IL). Mandibular fracture was classified based on sites, and patients’ socioeconomic status was classified based on United Kingdom National Statistics Socio-economic Classification (NS-SEC, 2010). Results: There were 466 (89.9%) males and 53 (10.1%) females. Based on Socio-economic Classification (NS-SEC, 2010), there was a preponderance of analytical class 6 (n = 217; 54.9%) and 8 (n = 127; 32.2%). Road traffic–related accident (n = 385; 74.2%) was the most common aetiological factor, and a total of 215 (41.4%) patients had a record of loss of consciousness. The mandibular body (n = 225; 32.0%) followed by the parasymphyseal (n = 187; 26.6%) regions were the most fractured sites. Closed-reduction technique was the predominant treatment modality. Conclusions: A road traffic accident was the most common aetiological factor for mandibular fracture, and the mandibular body had the highest frequency of fractures. Measures aimed at injury prevention should be continually reviewed and updated to limit the morbidity and economic burden on individuals.

Abstract
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.

Abstract
Introduction Ameloblastoma is the most common odontogenic tumour in Nigeria. A definite geographic variation has been observed in the frequency of odontogenic tumors from different parts of the world. However, there is no study on the regional variations in Nigeria. Hence, this study was designed to document the ethnic and geographical distribution of jaw ameloblastoma in Nigeria. Methods Archival data on ameloblastoma from 10 health facilities were obtained. Global Moran's I detected geographic clustering in its distribution while Local Getis Ord indicated the location of ameloblastoma clusters. Chi-square tested associations between variables at 0.05 level of significance. Results A total of 1,246 ameloblastoma cases were recorded in Nigeria. Besides substantial state variations, a South-North gradient was noticed in its distribution. Significant positive spatial autocorrelation was observed in the three major groups while ameloblastoma hotspots were found in the SouthWestern and Northwestern Nigeria. The Igbos had a higher prevalence of ameloblastoma outside their home region than within. Conclusion The study hypothesized that the geographical distribution of ameloblastoma in Nigeria is the result of all or one of the following: the country's tropical climate, migration patterns and health seeking behavior. Hopefully, these claims should lead to further enquiry on the underlying causes.

Abstract
Oral health as an integral component of overall health is provided by dental professionals (Dental surgeons/stomatologists, hygienists, dental nurses, technicians, community extension workers). Oral diseases in West Africa are dominated by gum/periodontal diseases, dental caries, orofacial trauma, cancrum oris/noma and oral cancer. Human resources and infrastructure for oral health services in West Africa are skewed towards the urban areas where the rich live, while the rural poor have relatively little or no human resources and infrastructure. The development of human resources for oral health started much later than for other health services in West Africa. In all countries, the training of dentists at undergraduate level started after independence. In Nigeria, postgraduate training in dental surgery took off more than 10 years after the graduation of the first set of undergraduate dental surgeons. To meet contemporary realities for improved dental services with a substantial reduction of all oral health diseases in the region, there is need to review the 1998 WHO health strategies.

Abstract
BACKGROUND Worldwide, it has been acknowledged that feedback from students and trainees is important for evaluation of training. However, there is limited data on the professional experiences, expectations and attitude of residents in dentistry to their training. AIM This study aimed to analyse the professional experiences, expectations, and attitudes of dentistry residents to training in Nigeria. DESIGN OF THE STUDY Cross-sectional study. SETTING All the accredited Nigerian Teaching Hospitals with dental surgeons undergoing residency training in any of the 10 specialties examined in West Africa. METHODOLOGY The study was conducted through a self- administered closed anonymous 46-items questionnaire adapted from that used for general surgery residents in the United States of America. The collected data included various aspects of the technical, human and professional domains of the expectations, attitudes and perceptions of dental residents to their training. Data from the questionnaires were collated and entered into Microsoft Excel version 10, 2002 (Microsoft, Redmond, WA, USA) and processed using STATA software (StataCorp LLC, Texas, USA). Categorical variables were calculated as proportions and percentages with 95% corresponding intervals. χ2 - test was used to analyse the association between selected demographic characteristics and some of the responses. Fischer's exact test was done where necessary. Statistical significance was set at p≤0.05 and tests were two- sided. RESULTS Nigeria has 11 accredited training institutions for residency in dentistry, of which 214 residents participated representing 93% of the estimated total. Most were males (133, 65.2%) with male to female ratio of 1.9:1. Residents aged between 30-34 years of age made up 41.5% while 77.4% were married. Close to one third (31.8%) were residents in oral and maxillofacial surgery. Residents expressed low level of satisfaction with the quality of residency training (64, 30.3%; 95% CI 24.5-36.9) and believe that they had appropriate level of operating skill from their training (96, 45.3%; 95% CI 38.6-52.1). Few agreed that the training programme had adequate support structures for struggling residents (64, 30.3%; 95% CI 24.5-36.9) but many (105, 65.2%; 95% CI 57.5-72.2) felt the residency programme took too long. More males (31.8%) than females (14.9%) expressed satisfaction with the level of didactic teaching during the residency programme with statistically significant difference (p=0.032). Orthodontic residents expressed the greatest approval (54.5%) for the support structures put by the training programme for struggling residents, while the least were in oral medicine (12.5%) with high statistically significant difference (p=0.014). The level of support from faculty/departmental member to struggling resident was felt to be most adequate by those who had passed the primaries exam (69.5%) with statistically significant difference from other residents (p= 0.021). CONCLUSION Overall, this study showed that Nigerian dentistry residents had low level of satisfaction with the quality of their training indicating the need for a holistic review of the training curriculum and conduct of trainers. There is need to reinforce motivating and tackle demotivating factors identified in this study to improve the response of dentistry residents to their training as these would improve the value of competency assessments undertaken by the postgraduate colleges while sustaining interest in the profession for the interest of the wider society.

Abstract
OBJECTIVES Orofacial cysts are broadly divided into odontogenic and nonodontogenic types, epithelial or non-epithelial, and developmental or inflammatory in origin. The odontogenic cyst is an osseous-destructive lesion that most commonly affects the jaw. It is formed by activation of odontogenic cell rests entrapped within the bone or gingival tissue of the jaws, such as the epithelial remains of Malassez, the dental lamina (cell rests of Serres), or the enamel organ. METHODS We performed a retrospective study of all histologically diagnosed cysts of the orofacial region seen at the Maxillofacial clinic of the Ahmadu Bello University Teaching Hospital, Nigeria, between January 2003 and December 2012. RESULTS Over the 10-year study period, 64 cases of cystic lesions of the orofacial region were seen in 1162 pathological specimens, representing 5.5%. Of these, there were 35 (54.7%) lesions in males and 29 (45.3%) in females giving a M:F ratio of 1.2:1. The age of the patients ranged from 4-64 years old (mean = 26.3 years). Dentigerous cyst (n = 21; 32.8%) was the most predominant lesion followed by periodontal (n = 12; 18.8%) and radicular cysts (n = 10; 15.6%). CONCLUSIONS Cysts of the orofacial region are common in this environment and like previous studies from Nigeria odontogenic cysts are not uncommon, the most predominant being dentigerous cysts.

Abstract
INTRODUCTION Adenomatoid odontogenic tumor (AOT) is a benign lesion originating from the dental lamina or its remnants. It is a relatively uncommon neoplasm representing about 3% of all odontogenic tumors. The aim of this study was to examine the clinical and radiological characteristics of AOTs in five major tertiary centres in Nigeria. METHODS Archival hospital-based data stores of five tertiary health facilities in Nigeria were accessed. Case files and biopsy records were retrieved to obtain relevant information. Data was collected according to a proforma for standardization and entered into and analysed using SPSS for Windows (version 20.0; SPSS Inc. Chicago, IL). RESULTS 61 (4.5%) cases of AOT were documented. The age range was 8-46 years with a mean age of 20.4±9.9 years. Male: Female ratio was 1:1.3. The anterior maxilla had 34 (55.8%) cases and the anterior mandible had 20 (32.8%) cases. 40 (65.6%) follicular cases, 20 (32.8%) extra-follicular cases and 1(1.6%) extra-osseous case were found. 31 cases (61.1%) were associated with impacted teeth and the upper canine was involved in 19 (57.6%) cases. CONCLUSION This study showed AOT to be more common in the maxilla, more in females, most often associated with impacted canines, however, the suggestion of AOT being a "Two third tumour" was not observed in this study.

Abstract
The two main forms of myositis ossificans are congenital and acquired. Either form is rare in the head and neck region. The acquired form is often due to trauma, with bullying as a fairly common cause. This report of myositis ossificans of the platysma in an 11-year-old female patient emphasizes the need for a high index of suspicion in unexplainable facial swellings in children and the benefit of modern investigative modalities in their management.

Abstract
Ameloblastic carcinoma is a malignant form of ameloblastoma defined by histological evidence of malignancy in primary, recurrent, or metastatic tumor. Such a tumor is rare, and the maxilla is an unusual site. Due to its rarity, the characteristics of this tumor in the maxilla have not been well described. Case 1: A 55-year-old, ill-appearing Nigerian male presented to our center with left maxillary swelling of seven-year duration. The swelling had been slow-growing and painless until one year prior, when the growth became rapid and was coupled with severe pain. The swelling affected both oral function and facial esthetics, and the patient reported difficulty breathing. There was a maxillary, ulcerated swelling extending from teeth 12 to 18 and blocking the left nostril. The involved teeth were moderately mobile. Case 2: A 32-year-old male farmer presented with recurrent right maxillary swelling of six-year duration. Prior to this episode, he had undergone surgery for ameloblastoma (follicular type). The present swelling was fungating through the skin and protruding into the right nostril. Ameloblastic carcinoma is an aggressive odontogenic tumor that requires aggressive surgical treatment.

Abstract
OBJECTIVES Infection involving the orbit, zygomatic space, lateral pharyngeal space, or hemifacial and oral floor phlegmon is referred to as cervicofacialvinfection (CFI). When diagnosis and/or adequate treatment are delayed, these infections can be life-threatening. Most cases are the result of odontogenic infections. We highlight our experiences in the management of this life-threatening condition. MATERIALS AND METHODS This was a retrospective study of patients who presented with CFI from December 2005 to June 2012 at the Oral and Maxillofacial Surgery Clinic or the Accident and Emergency Unit of Ahmadu Bello University Teaching Hospital (Zaria, Nigeria). The medical records of all patients who presented with either localized or diffuse infection of the maxillofacial soft tissue spaces were retrospectively collected. Data collected was analyzed using SPSS version 13.0 and are expressed as descriptive and inferential statistics. RESULTS Of the 77 patients, 49 patients (63.6%) were males, a male to female ratio of 1:7.5. The ages ranged from two years to 75 years with a mean of 35.0±19.3 years, although most patients were older than 40 years. The duration of symptoms prior to presentation ranged from 6 to 60 days, with a mean of 11.0±9.4 days. More than 90% of the patients presented to the clinic within the first 10 days. The most commonly involved anatomical space was the submandibular space (n=29, 37.7%), followed by hemifacial space (n=22, 28.6%) and buccal space (n=7, 9.1%). Ludwig angina accounted for about 7.8% of the cases. CONCLUSION CFI most commonly involves the submandibular space, typically affects individuals with a low level of education, and is influenced by traditional medical practices. Despite improved health care delivery, CFI remains a significant problem in developing countries.

Abstract
BACKGROUND The salivary glands consist of three major paired glands (the parotid, submandibular and sublingual) as well as numerous minor salivary glands, situated mostly in the oral cavity but also found in the pharynx, larynx, trachea, and sinuses. Tumours of salivary glands show a wide variety of pathologic types varying from benign to malignant. More salivary gland tumours are benign than malignant. PATIENTS AND METHODS Data for this study were obtained from retrospective survey of case notes of all patients with Salivary gland tumours seen at the Maxillofacial Unit, Ahmadu Bello University Teaching Hospital, Shika, Zaria between January 2003 and August 2013. RESULTS There were 135 patients 73 (54.1%) females and 62 (45.9%) males within the age range of 2.5 to 80 years (41.85 years). Thirty nine (28.9%) were benign while 96 (71.1%) were malignant. Major salivary glands were involved in 60.7% of tumours; the rest 39.3% involved minor salivary glands. Pleomorphic adenoma (86.7%) formed the bulk of benign tumours while adenoid cystic carcinoma (47.5%) was the predominant malignant tumour of salivary glands. Of 135 patients (n=,57.1% had surgery in our institution and were followed up. Those with malignancy also benefited from radiotherapy, chemotherapy or palliative oncology treatment. CONCLUSION Management of salivary glands tumours in our environment is a challenge due to late presentation and the size of the tumour.

Abstract
INTRODUCTION Pleomorphic adenoma or mixed tumour is a benign salivary gland tumour, presenting usually in the parotid or submandibular glands. This tumour contains elements of both epithelial and mesenchymal origin. They are the most common tumours (50%), (60-65%) of the major and minor salivary glands. The palate is considered as the most common intraoral site (42.8-68.8%), followed by the upper lip (10.1%) and cheek (5.5%). CASE REPORT A 37 year old female Nigerian house wife was seen with a four year history of painless slowly progressive upper lip swelling. Prior to her presentation, she had surgery for same swelling in a peripheral hospital. All other histories were not significant. CONCLUSION PA remains the commonest benign minor salivary gland neoplasm and excision with safe margins the treatment of choice.

Abstract
INTRODUCTION Post operative care of sutured wound is important after surgery. Sutured wounds within the oral cavity are kept clean through frequent rinses with either normal saline, chlorhexidine mouth rinses, hydrogen peroxide diluted with saline, or fresh tap water. PATIENTS AND METHODS The patients were randomised into 3 groups (A, B and C). The container used had 34 chlorhexidine, 34 warm saline and 32 warm water mouth rinses. The latter served as control. All selected patients had scaling and polishing done preoperatively when needed. All participants in each group did not receive antibiotics but received analgesics (paracetamol 1 g 8 h for 5 days,). RESULTS There were 49 females and 51 males, in the age range between 18 and 50 years. Microorganisms were found to grow on sutures with streptococcus viridians predominating followed by staphylococcus epidermides. The effects of chlorhexidine, warm saline and warm tap water mouth washes were not statistically significant. CONCLUSION Chlorhexidine, warm salt water and warm tap water averagely produced the same number of colony forming units of bacteria, which shows that the three different mouth washes are equally effective as post-operative mouth rinses after oral surgery.

Abstract
OBJECTIVES Dislocation of the temporomandibular joint may occur for various reasons. Although different invasive methods have been advocated for its treatment, this study highlights the value of non-invasive treatment options even in chronic cases in a resource-poor environment. MATERIALS AND METHODS A seven-year retrospective analysis of all patients managed for temporomandibular joint dislocation in our department was undertaken. Patient demographics, risk factors associated with temporomandibular joint dislocation and treatment modalities were retrieved from patient records. RESULTS In all, 26 patients were managed over a seven-year period. Males accounted for 62% of the patients, and yawning was the most frequent etiological factor. Conservative treatment methods were used successfully in 86.4% of the patients managed. Two (66.7%) of the three patients who needed surgical treatment developed complications, while only one (5.3%) patient who was managed conservatively developed complications. CONCLUSION Temporomandibular joint dislocation appears to be associated with male sex, middle age, yawning, and low socio-economic status, although these observed relationships were not statistically significant. Non-invasive methods remain an effective treatment option in this environment in view of the low socio-economic status of the patients affected.

Abstract
INTRODUCTION Chondromyxofibroma (CMF) is exceedingly rare, accounting for 0.5% of the 10,065 bone tumors categorized by Unni and Inwards and 1.6% of their catalog of benign bone tumors. Only 2 of the 50 chondromyxoid fibromas included in their study occurred in the skull. Chondromyxoid fibroma of the maxillofacial region is typically seen in patients in the 2nd-3rd decade of life with slight female predominance. It is more commonly seen in the maxilla and is unusual in the sphenoid and ethmoid sinuses. The tumor is composed of hypocellular chondroid or myxochondroid tissue with multinucleated giant cells. CASE REPORT A 30 year old Nigerian house wife was seen at the Oral and Maxillofacial clinic of the Dental and Maxillofacial Department of the Federal Medical Centre Lokoja with a 4 year history of Rt mandibular swelling which was initially slow growing and painless and difficulty in eating. The whole lesion was removed and result confirmed the previous biopsy of chondromyxofbroma of the jaw. CONCLUSION Patients with CMF need close monitoring due to high rate of recurrence with cases of malignant transformation at rate of 1-2%, and this seems to have occurred following irradiation.

Abstract
INTRODUCTION The objectives of this prospective randomized study were to clinically evaluate the longevity of resorbable sutures (chromic catgut and vicryl) and determine the effect of chlorhexidine mouth wash on their absorption time in oral surgical procedures. Both sutures were of size 3/0 with round body needle and were placed using the standard technique. METHODS AND MATERIALS One hundred patients selected for the study were divided into two groups of 50 patients each (vicryl and chromic catgut groups). Each group was subsequently subdivided into chlorhexidine (17 cases); warm saline mouth wash (17 cases) and warm water mouth wash (16 cases (control). RESULTS The sutures were placed during various minor surgical procedures e.g. third molar surgery (65 cases), incisional biopsy (7 cases), excisional biopsy (8 cases), sutured lacerations (10 cases) and malar elevations through intraoral upper buccal sulci approach (8 cases) and 2 cases of cystic enucleations. The mean longevity of chromic catgut for chlorhexidine was 11.4 days with a range of 5-16 days. The patients, who used warm saline mouth wash, had a mean longevity of 11.7 days with a range of 7-24 days. The mean longevity of vicryl in patients that used chlorhexidine was 22.7 days, with a range of 14-36 days and that of warm saline mouth wash was 24.5 days with a range of 14-47 days. CONCLUSION The resorbable sutures investigated have a mean longevity, which was slightly shorter than the figure stated by the manufacturer. Chlorhexidine was found to have no appreciable effect on absorption time of the sutures.

Abstract
Spontaneous bone regeneration is an uncommon condition following traumatic or iatrogenic bone loss. The factors responsible for its occurrence are yet to be fully elucidated. This report presents spontaneous bone regeneration following mandibular resection for a giant odontogenic myxoma in a 16-years-old Nigerian male. New bone formation was observed at the postoperative fourth week and has continued for one year after. Likely factors that favor this occurrence are critically examined. The advantages of spontaneous bone regeneration in resource-poor settings include low biologic and economic costs as compared to bone grafting.

Abstract
INTRODUCTION Ameloblastoma is rare worldwide. Delayed treatment can result in significant morbidity from facial deformity and infiltration of adjacent tissues. Mortality can occur from invasion of vital structures in the head and neck, super infection, recurrent and even distant metastases. Recurrence after radical treatment is not common. CASE REPORT This paper presents a case of soft issue recurrence in the chin 21 years after radical resection of the mandible for ameloblastoma. The iliac crest bone grafted to the site was not involved in the tumour recurrence. Conclusion. Radical surgical resection is accepted treatment for solid/multicystic ameloblastoma. However, the surgical review should be for life as recurrence can occur after a long interval.
