Little research has evaluated the orthopanto-mograph for these purposes AIM: To compare the data taken from orthopantomographs and lateral cephalograms in the investigation of vertical jaw relationships and to assess correlation between measurements MATERIALS AND METHODS: The gonial angle, ramus height and condyle angle were measured for each patient on the two radiographs and these data compared for the three different facial growth types, dolichofacial, mesofacial and brachyfacial. RESULTS: In subjects with normal (meso-) or horizontal (brachy-) growth patterns, there were no significant differences between the mean and median values for the gonial and condyle angles, but the ramus heights showed significant differences The data of the vertical (dolicho-) growth pattern patients recorded significant differences only between the data for the gonial angles and the ramus heights. Significant correlations were found between the gonial angles and the condyle angles for all three growth patterns, but not for ramus heights. CONCLUSION: in comparing the data from the two radiographs, the angular measurements showed high correlation and predictability whilst linear measurements showed inconsistency <![CDATA[<b>The effectiveness of a tooth brushing programme for children in the Ehlanzeni district of Mpumalanga</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162018001000004&lng=pt&nrm=iso&tlng=pt PURPOSE: To evaluate the effectiveness of a tooth brushing programme in a community trial in the Ehlanzeni district, Mpumalanga METHODOLOGY: Two samples of 250 children, 8-10 years old and in grade 3, were randomly selected from schools in the district. The intervention group comprised children who had taken part in the brushing project since it was incepted in 2012. The control group comprised children who had not participated. Caries was scored according to WHO Criteria (1997) and odontogenic infections using the PUFA/ pufa index. These data and the treatment needs of the two groups were compared statistically RESULTS: The prevalence of dental caries (primary and permanent teeth) was 57.2%, intervention group and 74.8%, control group. The intervention group recorded DMFT of 0.15 and a dmft of 1.82, whilst the control group recorded 0.38 and 2.50 respectively Odontogenic infections occurred in 22% of the intervention group (mean 0.40), compared with 36% in the non-intervention group (mean 0.82). The intervention group presented with 30.8% less dental caries and 63.6% less odontogenic infections than the control group. CONCLUSION: The results of the study show that this targeted population approach resulted in significantly less caries in the intervention group than in the control group <![CDATA[<b>The perception of patients of the professionalism of dental students at a Tertiary Oral Health Centre, South Africa</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162018001000005&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Professionalism in the healthcare setting refers to the standards a patient can expect from his/her healthcare practitioner (HCP). Appearance, behaviour, attitude and communication skills are all attributes of professionalism AIM: To assess the perceptions of patients of the professionalism of oral health students at an South African Tertiary Oral Health Care Centre (SA-OHC METHODS: A cross-sectional, analytical study was conducted using an interviewer-administered questionnaire. Photographs depicting various dress codes were included in the questionnaire given to patients RESULTS: A total of 118 patients with a mean age of 44 years (sd-18.16) were interviewed. The majority (n=76; 65%) were previously booked patients; 72% female; 53% black; and 85% in the earning category of up to R3000 p/m. The Cronbach alpha score was good at 0.7. 96% of patients agreed that the students looked professional in lab coats (79.5%), then surgical gowns (55.9%) and thirdly scrubs (50.9%) although not in formal wear (66%. In terms of communication skills and behaviour, students were highly rated (91%-99%). Payment classification, education level and gender influenced patient perceptions (p<0.05 CONCLUSION: Students were highly regarded by patients generally, and patients perceived lab coats and surgical gowns to be more professional than formal garb <![CDATA[<b>Effect of aging in artificial saliva on the shear bond strength of resin composite</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162018001000006&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Artificial saliva as an in vitro aging medium may be an effective method of simulating the clinical degradation of resin composite restorations. The composition and desirable properties of artificial saliva are not yet standardised. Incorporation of oral bacteria may more closely approximate the intra-oral effect of saliva on composite restorations. Surface deterioration on an old broken restoration repaired with fresh composite may result in a weak adhesive interface, measureable, in vitro, by a shear bond strength test AIM OF THE STUDY: To evaluate whether artificially aged composite affects the shear bond strength of the adhesive interface with fresh composite. MATERIALS AND METHODS: A silicone mould was used to fabricate 240 composite cylinders. 120 were aged in a solution of artificial saliva for 28 days. The remainder served as controls. The specimens were divided into seven groups of twenty, each group being subjected to a different repair protocol. Shear bond strength testing was then carried out on the repaired composite blocks. RESULTS: Aging in artificial saliva resulted in a reduction of 15.04% to 21.1% in shear bond strengths compared with un-aged composite CONCLUSION: Composite samples aged in artificial saliva had a significantly weaker repair interface compared with non-aged samples <![CDATA[<b>Maxillofacial Radiology 166</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162018001000007&lng=pt&nrm=iso&tlng=pt INTRODUCTION: Artificial saliva as an in vitro aging medium may be an effective method of simulating the clinical degradation of resin composite restorations.

Subsequently pulpal necrosis, internal resorption and mobility of the tooth occurred, complicating the case. A repeat pulpotomy was performed together with the use of triple-antibiotic paste (TAP). At the 10-month follow-up no clinical signs of disease were found. Complete healing of the furcal radiolucency was demonstrated, with bony infill, no mobility and resolution of the previous widening of the periodontal ligament. It appears that TAP may be a viable treatment modality to enable retention of necrotic primary teeth with a poor prognosis. <![CDATA[<b>The jaw muscles and central sensitization in migraine</b>]]> http://www.scielo.org.za/scielo.php?script=sci_arttext&pid=S0011-85162018001000009&lng=pt&nrm=iso&tlng=pt Sensitization of the trigeminal subnucleus caudalis (Vc) is an important process in the generation of migraine pain.
