The influence of cephalometrics on orthodontic treatment planning ?
Peter G. Nijkamp et al EJO Dec 2008

Since its introduction, cephalometrics, i.e. cephalometric radiography and analysis, has been used for orthodontic treatment planning. However, the effectiveness of this diagnostic method remains questionable. A randomized crossover study was designed to assess the influence of cephalometrics in orthodontic treatment planning of individual patients. Diagnostic records of 48 subjects (24 males and 24 females aged 11–14 years) were divided in two stratified groups and assigned to one of two combinations: A, dental casts only, and B, dental casts, cephalometric radiographs, and analysis. The records were presented to 10 orthodontic postgraduates and four orthodontists for formulation of orthodontic treatment plans containing a dichotomous decision regarding the use of a functional appliance (FUNC), rapid maxillary expansion (RME), and extraction (EXTR). The combination of FUNC + RME + EXTR was used as the basis of the outcome measure. Agreement on orthodontic treatment planning using all possible comparisons of diagnostic records of individual patients (AB, AA, and BB) was assessed and overall proportions of agreement (OPA) were calculated for orthodontic postgraduates and orthodontists separately.

Median OPA were 0.60 (AB), 0.65 (AA), and 0.60 (BB) for orthodontic postgraduates and 0.50 (AB), 0.75 (AA), and 0.50 (BB) for orthodontists. Irrespective of the level of experience, neither consistency of orthodontic treatment planning between both combinations of diagnostic records showed a statistically significant difference (P > 0.05) using Wilcoxon signed rank test nor did consistencies and agreement of orthodontic treatment planning after the addition of cephalometrics. It appears that cephalometrics are not required for orthodontic treatment planning, as they did not influence treatment decisions.

Stomach Ulcer Bug Causes Bad Breath

For the first time, scientists have found Helicobacter pylori living in the mouths of people who are not showing signs of stomach disease. More HERE

Relationship between halitosis and psychologic status
Triple O Nov 2008

Objective: To examine the psychosomatic aspects of patients complaining of halitosis.
Study design
Breath malodor in 165 patients was measured using an organoleptic test (OLT), sulfide monitoring, and gas chromatography. Clinical evaluation included oral examination, OLT, and volatile sulfur compound measurement. The psychologic condition of patients was assessed using the Cornell Medical Index (CMI).
Results
Every item in the CMI questionnaire was negatively correlated with the OLT scores. Nine of 21 subjects (42.9%) diagnosed with pseudohalitosis and approximately 20% of subjects diagnosed with genuine halitosis were considered to be provisionally neurotic. Subjects with pseudohalitosis reported significantly higher physical scores, but not mental scores, than those with genuine halitosis. Subjects with physiologic halitosis showed significantly higher symptoms of depression than those with oral pathologic halitosis.
Conclusion
The psychologic condition of patients complaining of halitosis was associated with the actual degree of malodor and the clinical characteristics.

Influence of bone density on implant stability parameters and implant success: a retrospective clinical study

Background
The aim of the present clinical study was to determine the bone density in dental implant recipient sites using computerized tomography (CT) and to investigate the influence of bone density on implant stability parameters and implant success.
Methods
A total of 300 implants were placed in 111 patients between 2003 and 2005. The bone density in each implant recipient site was determined using CT. The peak insertion torque values were recorded with OsseoCare machine. The implant stability measurements were performed with Osstell instrument immediately after implant placement, 6, and 12 months later.
Results
Of 300 implants placed, 20 were lost, meaning a survival rate of %. 93.3 after three years. The mean bone density, insertion torque and RFA recordings of all 300 implants were 620+/-251 HU, 36.1+/-8 Ncm, and 65.7+/-9 ISQ at implant placement respectively; which indicated statistically significant correlations between bone density and insertion torque values (p<0.001), style="font-weight: bold;">Conclusion CT is a useful tool to determine the bone density in the implant recipient sites, and the local bone density has a prevailing influence on primary implant stability, which is an important determinant for implant success.

Advancements in Digital Imaging
What Is New and on the Horizon? JADA Nov 08

Cone beam computed tomography (CBCT) is a diagnostic imaging technology that is changing the way dental practitioners view the oral and maxillofacial complex. CBCT uses radiation in a similar manner as does conventional diagnostic imaging and reformats the raw data into Digital Imaging and Communications in Medicine (DICOM) data. DICOM data are imported into viewing software that enables the manipulation of multiplanar reconstructed slices and three-dimensional volume renderings. DICOM data also may be used in third-party software to aid in dental implant placement, orthognathic surgery and orthodontic assessment. Full paper here

Got A Headache? It Is Your Dentist, Not Doctor Who Could Fix It!

Headaches, migraines, pain behind our eyes, sinus, and even neck and shoulder pain are all ailments that would warrant a trip to the doctors - that is until now. As Rahul Doshi and Ashish B. Parmar, award-winning cosmetic dentist's from Extreme Makeover and Partners at The Perfect Smile Studios & Academy in the South East, United Kingdom, explain, it could well be your dentist who holds the key to your pain relief.

As the cosmetic dentistry specialists outline, pains such as headaches are often classic symptoms of poor dental occlusion - the way your teeth meet when your jaw bites together. So, instead of popping paracetamol or visiting the GP, harmonising your teeth and jaw joints could affect more than just your smile. More HERE

Optical coherence tomography ? (OCT)

OCT is a noninvasive and nondestructive method for imaging the microstructural detail of oral tissue in situ, providing clinicians with quantitative and qualitative information. It is capable of evaluating the health of hard and soft tissue by providing a cross-sectional “optical biopsy” of tissue up to 3 mm in depth from the surface. The resultant imaging has an axial resolution of 1–10 µ, capturing structural details not possible with x-rays (and without the use of ionizing radiation). OCT imaging has the potential to detect and diagnose very early stages of disease in teeth, periodontal tissue, and mucosa. Early demineralization, remineralization, recurrent caries, tooth and restorative failures, root canals, periodontal disease, soft tissue dysplasias, and precancerous lesions can be imaged and monitored in real time on a computer monitor.

Distalize Your Molars EASY way

This works by use of Miniscrew implant supported distalization system (MISDS). This case report illustrates the use of MISDS to distalize the maxillary molars and retract the anterior teeth, providing noncompliance, nonextraction, and efficient approach for the orthodontic treatment of patients with Class II malocclusion, which is initially invisible. This report is published in AJODO in Nov 2008 issue.

You may not be aware we Indians started using Mini implants much before it became popular in western world. Indian mini implants (titanium) are much cheaper and have the same function as all other. See the case below which was distalised / corrected in 6 months. To order or see more CLICK HERE

Dental erosion linked to dysmenorrhea.
Department of Restorative Dentistry, Temple University, School of Dentistry, Philadelphia, Pennsylvania, USA. In Gen Dent Nov. 2008 This article examines the case of a woman with hard dental tissue loss that was similar to perimolysis caused by bulimia nervosa; however, the patient's health history, signs and symptoms, and dietary habits refuted any eating disorder. All extrinsic causes and the majority of intrinsic causes were examined carefully and eliminated. The patient had undergone endometrial surgery 32 years earlier to remove a tumor, a procedure that was believed to be unrelated to the dental professionals' realm; however, a detailed patient history revealed severe pain associated with abdominal cramps that were in concert with the menstrual cycle.

Over a period of nearly three decades, these cramps frequently caused forceful purging of stomach contents during episodes of dysmennorhea. The mechanism, force, direction, and frequency of purging closely resembled that of bulimia, producing similar (if not identical) consequential damage to the dental hard tissues. The process of identifying, differentially diagnosing, and finally determining the etiology of the erosion lesions was based on an in-depth knowledge of systemic disorders, recognition of various characteristics and causes of erosion lesions, and an accurately detailed systemic and dental health history.
