Impacted third molars have been implicated in oral infections, neoplastic conditions and late onset dental crowding AIMS AND OBJECTIVES: To assess the prevalence of third molar impaction among a sample of adult orthodontic patients in relation to their antero-posterior and vertical craniofacial skeletal patterns. DESIGN: A descriptive cross-sectional study METHODS: Orthopantomograms and lateral cephalograms of 62 adult orthodontic patients were assessed. Presence and type of M3 impaction according to Winter's and the Pell and Gregory's classifications were documented and the relationships of these data to the vertical and antero-posterior cranio-facial skeletal patterns were assessed. All analyses were performed using the SPSS package, version 22. Level of significance was set at p<0.05 RESULTS: Median age was 23.5years. Disto-angular impaction was commonest in the maxilla while mesio-angular and horizontal impactions were limited solely to the mandible (p<0.001). There was a significant relationship between Winter's classification of M3 impaction and the antero-posterior skeletal pattern (p=0.007). Pell & Gregory class 3 impactions were found almost entirely among patients with class II malocclusion, (p<0.001 CONCLUSION: M3 impaction is prevalent among the sample, the ore more severe impactions occurring in skeletal pattern II subjects <![CDATA[<b>Knowledge, attitude and practices of alcohol and smoking among undergraduate oral health students at a South African University</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162018000100006&lng=pt&nrm=iso&tlng=pt BACKGROUND: The prevalence of alcohol consumption and smoking among university students is high AIM: To determine the knowledge, attitudes and practices of alcohol consumption and smoking among undergraduate oral health students at a South African university METHODS: A cross-sectional study was conducted among dental and oral hygiene students (n=344) who were registered at a South African University in 2015. A self-administered questionnaire was used to collect information on socio-demographic characteristics, knowledge, attitudes and practices regarding consumption of alcohol and smoking. Data analysis included frequencies and correlations using chi-square tests,at a level of significance of p<0.05 RESULTS: A total of 269 (78%) students agreed to participate. The mean age was 22 years and 74% were female. More than a third (41%) reported consuming alcohol regularly while 11% reported being current smokers. More males reported indulging in both habits as compared with females. More than half felt that alcohol was acceptable as a social drink. The majority of clinical students (86%) associated periodontal diseases with smoking compared with pre-clinical students (74% CONCLUSION: The overall knowledge on social and health implications of excessive consumption of alcohol and smoking was adequate. The majority associated alcohol consumption and smoking with social activity <![CDATA[<b>Comparison of two methods of predicting mesiodistal widths of permanent canines and premolars in a sample of black South Africans</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162018000100007&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Accurate tooth size prediction of permanent successor teeth is important for treatment planning during the mixed dentition stage OBJECTIVES: To compare and determine the accuracy of two methods used to predict mesiodistal widths of permanent canines, first and second premolars in a sample of Black South Africans METHODS: Measurements of teeth were performed on study models of a sample of 100 children (50 males and 50 females) aged between 17 and 21 years. Digital calipers, accurate to 0.05mm. were used. Estimations of the widths of the permanent canines, first and second premolars (C+P1+P2) were performed for mandibular and maxillary arches using the Schirmer and Wiltshire and the Modified Tanaka-Johnston prediction methods. The estimated (C+P1+P2) values were then compared with measurements of the actual teeth on the study models RESULTS: Males presented significantly larger mesiodistal tooth dimensions than females. The Modified Tanaka-Johnston equation is accurate for females but overestimates actual tooth measurements for males. The Schirmer and Wiltshire method is accurate for male maxillary and female mandibular tooth sizes but overestimates male mandibular and underestimate female maxillary tooth sizes CONCLUSION: Both methods have deficiencies; however the Modified Tanaka-Johnston equation proved preferable because it overestimates rather than underestimates actual tooth sizes <![CDATA[<b>Intraoral repair protocols for fractured metal-ceramic restorations - Literature review</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162018000100008&lng=pt&nrm=iso&tlng=pt Metal ceramic restorations are still widely used for prosthodontic rehabilitation of compromised teeth and in general are durable and long lasting. However, post-fitting complications in metal-ceramic crowns and fixed partial dentures do occur. One of the most frequently encountered complications in metal-ceramic systems is the fracture of veneering porcelain, becoming a dental emergency, especially when located in the anterior region. Replacing the entire restoration may not be the most practical solution. Intraoral repair of the fractured porcelain offers an easy and cost-effective alternative. The exact protocol for repair varies with the type of fracture that has occurred. This paper provides an overview of various methods of repairing different types of porcelain fractures with an aim to help clinicians manage these dental emergencies in a more effective and conservative manner. <![CDATA[<b>Masticatory, temporal and buccal space infection in an immunocompromised patient: a case report</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162018000100009&lng=pt&nrm=iso&tlng=pt 'AIDS' (Acquired Immunity Deficiency Syndrome) is a term used to describe the various clinical syndromes, specific opportunistic infections or malignancies that can occur with HIV infection. Oral manifestations of these diseases are common in people with Human Immunodeficiency Virus (HIV) infection and may be due to a decline in immune function. Hence patients with AIDS are subjected to recurrent, life threatening opportunistic infection. This is a case report of a 70yr old female who presented with infection of the right buccal, masticator and submandibular spaces. A routine blood report revealed seropositivity for HIV infection. She was treated with antibiotics and underwent an incision and drainage following hospitalization. <![CDATA[<b>Maxillofacial Radiology 157</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162018000100010&lng=pt&nrm=iso&tlng=pt 'AIDS' (Acquired Immunity Deficiency Syndrome) is a term used to describe the various clinical syndromes, specific opportunistic infections or malignancies that can occur with HIV infection.
