Effect of screw diameter on orthodontic skeletal anchorage AJODO Aug 09
Ninety-six titanium alloy screws were placed into 24 hemisected maxillary and 24 hemisected mandibular specimens between the first and second premolars. Specimens were randomly and evenly divided into 2 groups. In the first group, 24 large-diameter screws (2.5 × 17 mm) and with 24 small-diameter screws (1.5 × 15 mm) were placed monocortically. In the second group, 24 large-diameter screws (2.5 × 17 mm) were placed monocortically and 24 small-diameter screws (1.5 × 15 mm) were placed bicortically. All screws were subjected to tangential force loading perpendicular to the miniscrew with lateral displacement of 0.6 mm.
Conclusions
In vitro, larger-diameter (2.5 mm) monocortical screws provide greater anchorage force resistance than do smaller-diameter (1.5 mm) monocortical screws in both the mandible and the maxilla. Smaller-diameter (1.5 mm) bicortical screws provide anchorage force resistance at least equal to larger-diameter (2.5 mm) monocortical screws. An alternative to placing a larger-diameter miniscrew for additional anchorage is a narrower bicortical screw.

Poor Endo may lead to Coronary Heart Disease
J Am Dent Assoc, Vol 140, No 8, 1004-1012
Results from numerous studies have suggested links between periodontal disease and coronary heart disease (CHD), but endodontic disease has not been studied extensively in this regard.
The authors evaluated the relationship between self-reported history of endodontic therapy (ET) and prevalent CHD in the Atherosclerosis Risk in Communities (ARIC) Study, aprospective epidemiologic study sponsored by the National Heart, Lung, and Blood Institute. The authors used multivariable logistic regressionto analyze data obtained from oral health questionnaires, medical evaluations and clinical dental examinations.
Results. Of 6,651 participants analyzed, 50.4 percent reported never having had ET; 21.5 percent reported having had ET one time; and 28.0 percent reported having had ET two or more times. Final multivariable regression models indicated that among participants with 25 or more teeth, those reporting having had ET two or more times had 1.62 (95 percent confidence interval [CI], 1.04–2.53) times the odds of prevalent CHD compared with those reporting never having had ET. Among participants with 24 or fewer teeth, no significant differences in CHD prevalence were observed among groups regardless of their history of ET.
Conclusions. Among participants with 25 or more teeth, those with a greater self-reported history of ET were more likely to have CHD than were those reporting no history of ET.
Clinical Implications. More accurate epidemiologic quantification of endodontic infection and inflammation is required before definitive conclusions can be made about potential relationships between endodontic disease and CHD. Get the BEST APICAL SYSTEM
Labial access opening in mandibular anterior teeth—An alternative approach to success
Objective: To compare the conventional lingual access to labial access preparation in mandibular anterior teeth in terms of achieving a straight-line access to the apex with maximum conservation of coronal tooth structure. Method and Materials: One hundred extracted human mandibular incisors with intact crowns and patent root canal configuration were collected, numbered, and weighed in a microbalance. Each tooth was radiographed in a labiolingual direction, traced, evaluated, and assigned into 1 of 5 classes as per the classification given by Zillich and Jerome (1981).The frequency of types of canal configuration in each class was determined as a percentage. The teeth were randomly divided into 2 groups of 50 teeth. Access was prepared lingually in group 1 and labially in group 2 to achieve a straight-line access to the apex. The amount of tooth tissue lost as a result of access preparation was measured for all teeth. Results: A total of 71 teeth had their tracing projections buccal and buccoincisal. The tooth tissue lost during lingual access was significantly more than that lost during labial access preparation (P < .001). Conclusion: A labial access opening for endodontic treatment of mandibular incisors would facilitate straight-line access to canals more consistently and conservatively.

Neurological deficit of the facial nerve after root canal treatment
Oral Surgery, Oral Medicine, Oral Pathology, Oral Radiology, and Endodontology
Volume 108, Issue 2, August 2009, Pages e46-e48
Here we report the unusual case of a patient who suffered neurological deficit of the facial nerve as a complication of a root canal treatment. During the canal treatment, 3% hydrogen peroxide and 90% ethanol rinses were performed. The present case demonstrated rinse toxicity to vital tissue as evidenced by severe clinical damage. Chlorhexidine can be used instead of potentially toxic rinses with good antimicrobiological results. Furthermore, special attention should be paid to determination of the root canal length and the integrity of the canal system before rinsing. Also irrigation should be applied at a low pressure.
Magnification in Dentistry, A useful tool ?
In spite of their significant cost, the relatively long learning curve associated with their use,
frustrations during use, their occasional need for being replaced and their peculiar appearance to patients, magnifying loupes assist all types of clinical dentists in producing higher-quality dentistry. Read full JADA article Here

"Dr. Mitra's extraordinary inventions have changed the field of dentistry for dentists and patients around the world," said Fred J. Palensky, Ph.D., executive vice president, Research and Development and chief technology officer at 3M. "Her discoveries will influence and benefit society for decades. The financial impact of her work is enormous and far-reaching. To date, her research has resulted in commercialized products that have contributed nearly $2 billion to 3M's revenue." MORE HERE
