How to Critique an article ..

Your final personal opinion about any scientific paper can be based on the collective answers of the following questions :
1. Title : is it appropriate and clear ?
2. Abstract : is it representative of the article and in correct form?
3. Purpose of the article : is it clearly stated ?
4. Errors of established facts or errors of interpretation of other’s work.
5. Is all the discussion relevant?
6. Are references the auther cited relevant to the topic?
7. Have any ideas been overemphasized or under emphasized?

TIPS : Interceptive Treatment

Weekly-Tips-ImageTips by Prof. Ali Habeeb :

When patients comes to clinic in early mixed dentition and after addressing the problems that patient has  , we should ask :

Is this  the RIGHT TIME to start treatment?

if not , then we should just go for two phases of treatment plan.

1st phase is to just interfere to prevent future problems like correcting anterior crossbite or urgently provide space for delayed unerrupted upper lateral incisor or using a lingual arch or TPA to prevent mesial migration of permenant molars if early loss of upper Es has occured ….etc.

Reproducibility of facial soft tissue landmarks on 3D laser- scanned facial images. 

Toma AM, Zhurov A, Playle R, Ong E, Richmond S. Reproducibility of facial soft tissue landmarks on 3D laser- scanned facial images. Orthod Craniofac Res 12:33-42, 2009.

SUMMARY :

Background – The three-dimensional (3D) measuring technology is useful to inspect facial shape in three planes of space (X, Y, and Z). Recent work has been directed to analyse craniofacial morphology using facial soft tissue landmarks to identify facial differences among population. The reproducibility of facial landmarks is almost necessary to ensure accurate 3D facial measurements.

Objective – The aim of this study is to assess the reproducibility of facial soft tissue landmarks using laser-scan 3D imaging technology.

Subjects and Methods – Facial landmarks were assessed for 30 15½-year-old British-Caucasian children (15 males and 15 females). The sample was recruited from the Avon Longitudinal Study of Parents and Children (ALSPAC). The 3D facial images were acquired for each subject using two high-resolution Konica ⁄ Minolta laser scanners. Twenty-one facial landmarks (63 X, Y, and Z coordinates) were identified and recorded on each 3D facial image by two examiners. The reproducibility of landmarks identification at 2-week interval was assessed for one of the examiners (intra-examiner). In addition, the reproducibility of landmarks was assessed between the two examiners (inter-examiner). Using Bland-Altman plots, both intra- and inter-examiner assessments had evaluated landmarks reproducibility in three dimensions for the sample divided by gender. The reproducibility of the 3D-coordinates for each landmark was considered under three categories (<0.5 mm, <1 mm, and >1 mm) for both intra- and inter- examiner reproducibility assessments.

Value of two cone-beam computed tomography systems from an orthodontic point of view.

Korbmacher H, Kahl-Nieke B, Schöllchen M, Heiland M. Value of two cone-beam computed tomography systems from an orthodontic point of view. J Orofac Orthop 68:278- 289, 2007.

SUMMARY by Dr. DALIA BASYONI :

* CBCT cannot replace OPG, which remains our primary imaging modality.

* In complex cases involving multiple findings in different regions, CBCT is more desirable than conventional radiographs.

*  Standard operating procedures (SOP) to use CBCT:

•  clefts of the lip, jaw and palate and cases of impacted teeth. Continue reading Value of two cone-beam computed tomography systems from an orthodontic point of view.

In the beginning, I would like to welcome all visitors of our specialized blog.This blog was mainly created to post , discuss and share scientific issues in Orthodontics especially what is related to periodic meetings held in King Abdulaziz University in Jeddah (Saudi Arabia ) as a part of the 4 to 5 years Saudi Board of Orthodontics program.The idea that led us to create this blog was inspired by our Professor ; Dr.Ali Habib who always spends his efforts for the success of this program.

In our weekly meetings we have a book review , literature review and one or two case presentations presented by the orthodontic residents and supervised by our great instructors.Summary of the articles presented as well as other scientific issues that were raised during the meetings will be posted in this blog and left open for comments.

I hope this blog will expand to include more activities in the future.

ENJOY Orthodontics .. It is a wonderful speciality 🙂
