Anthropometry is defined as the scientific study of the measurements and proportions of the human body. To date, the most used methods for the acquisition of facial anthropometric parameters are direct method employing calipers and protractors tools, which are time-consuming, or indirect methods employing three-dimensional (3D) imaging systems, which are expensive. Despite the possible advantages of two-dimensional (2D) photography, it is not widely explored due to complications such as resolution and distortion of digital photos. The objective of this study is to
assess the accuracy of the Digital Single-Lens Reflector (DSLR) camera as an indirect method against direct method at different aperture and distance to subject. Adults aged 20-45 years were voluntarily recruited in this study (n=24). Twelve facial anthropometric parameters were measured for each participant using direct anthropometry (sliding caliper), and indirect anthropometry (DSLR camera). When placing the DSLR camera at 2.0 meters from subjects with f/6.3 aperture, nine facial anthropometric parameters were obtained accurately (p> .05). The findings suggested that
the accuracy of the DSLR camera as an indirect method for the acquisition of facial anthropometric parameters was established at the aperture setting of f/6.3 and the object distance at 2.0 meters. Therefore, it can be recommended as a facial anthropometry acquisition technique.
Platelet Rich Fibrin (PRF) is a natural autologous fibrin matrix and is an effective biomaterial product. The application of PRF in oral surgery is not limited to tissue regeneration, but it has been utilized in several minor and major oral surgical procedures. Numerous studies have proven that either alone or in combination with bone graft, PRF acts as bone and soft tissue regeneration and it is able to stimulate physiological wound healing. This case report will introduce the utilization of PRF combined with autogenous bone graft in restoring four walls dental socket defect due to post-surgical extraction complication and plan for implant placement in the future. It acts in the form of a resorbable membrane and stem cell connector to the bone. After 3 months post-surgery review, there was no signs of infection or tissue rejection and the harvested bone was still viable. The PRF is comparable to commercially available membrane in the market, where clinical results can be predicted and possibility of reduction in post-surgical complications is achieved. This is due to 1) its compatibility with bone graft materials notably autogenous type, 2) induced neovascularisation and 3) reduction in inflammatory reaction. Our team is confident that the result of PRF at the edentulous region for rehabilitation purposes is beneficial and cost-effective to our patients.
Anthropometric analysis provides the most reliable comparison of the body forms by using specific landmarks determined in respect of anatomical prominences. The knowledge of unique shape, anatomy and dimensions of the nose is very useful for surgeon undertaking its repair and reconstruction. Prosthetic rehabilitation also requires the ability to imagine the position and dimension of the nose within the facial proximity. Therefore, the access to nasal data for each
population are advantageous. The aims were to measure parameters of external nose of a Malay population and to determine the significant difference in nose value parameters between gender and age group. The direct anthropometric measurements were carried out in 86 Malay subjects within the age range of 18 to 55 years old who attended UiTM dental clinic. Nasal landmarks were
identified, and the nose parameters were measured using digital calliper. The values were expressed as mean, standard deviation and range. Nasal height, width and length of the nasal bridge were higher in male. The intercanthal width and philtrum length were statistically not significant for both genders. There were significant differences in nasal width, philtrum length, intercanthal width and outer intercommisural mouth width between the three age groups. However, the height of the nose, length of the nasal bridge and nasal index between age group were statistically not significant. The male population and the 41-55 years age group have higher nose value parameters. The most common type of nose was platyrrhine: broad. This study also suggested that Malay population have medium broad nose as the nasal index for both genders was ≤ 84.90.

The objective of this study is to assess Universiti Teknologi MARA (UiTM)
dental students’ perspective on a novel patient educational kit in helping them
to deliver post-dental extraction care instructions. All undergraduate clinical
year dental students of the Faculty of Dentistry, UiTM were recruited for this
cross-sectional study. 87.8% of these students have volunteered to participate
in this study. An 8-minutes introductory video of the Post-Dental Extraction
Care kit (PDEC-kit) was played when simultaneously showcasing the tools in
the PDEC-kit to the participants. The participants then answered a set of
validated self-administered questionnaires online on their perception and
suggestions for improvement of the PDEC-kit, which comprises of 20 items that
are rated by a 7-point Likert scale along with 7 open-ended questions. A total
of 216 students participated voluntarily in this study. A vast majority of
participants agreed that the PDEC-kit is useful (99.1%), easy to use (98.7%),
and can improve patient’s understanding regarding post-dental extraction care
instructions (99.1%). The information provided in the kit was also found to be
appropriate for the patients (97.2%). Interestingly, students who had clinical
experience in performing dental extractions have rated significantly higher
scores for half of the questions (p
