Dentist fear kills 8 year old, kiss at your own peril, truth about Implants

Truth about Dental Implants Revealed
With inputs from prof. Björn U Zachrisson

"The better dentist you are, the fewer implants you insert"
by Dr. Jan Lindhe April 2007

From a long-term (esthetic) perspective, a tooth or root is almost
always better than an implant

Disadvantages of Implants (Advantages are well known)

Progressive infraocclusion even in adults, see fig below, look at the left max lateral incisor progressively appearing in infra occlusion.

This happens more often in following situations:
  • Young adults
  • Vertical growers
  • (high angle cases)
  • Gummy smiles
  • Open bites
  • Females
Blue-coloring of labial gingiva, very damaging in anterior zone, See fig



Visible abutment with time (metal, porcelain), see fig


Interdental recession particularly distal papilla, see how gingival margins differ, fig below


Don´t upright like natural incisors
Non-adjustable by orthodontic means
Not easy to make crown entirely natural
No long term observations (> 10-15 years))

Use pomegranate juice as mouthwash for healthy teeth/gums

Pomegranate components have properties that could promote oral health, including reducing the risk of gingivitis. The present study examined young adults (n = 32, split evenly among both genders), for the effects of 4 weeks of thrice daily mouth rinsing with the pomegranate (Punica granatum L.) extract PomElla® dissolved in water. This treatment changed salivary measures relevant to oral health including gingivitis. The changes were: reduced total protein (which can correlate with plaque forming bacteria readings), reduced activities of aspartate aminotransferase (an indicator of cell injury), reduced alpha-glucosidase activity (a sucrose degrading enzyme), increased activities of the antioxidant enzyme ceruloplasmin (which could give better protection against oral oxidant stress) and increased radical scavenging capacity (though this increase was significant only by nonparametric statistical analysis). A placebo of cornstarch in water did not affect these measures. These data raise the possibility of using pomegranate extracts in oral health products such as toothpaste and mouthwashes.

In India ayurveda has used pomegranate and its peel for various ailments and disorders and west is discovering it now.


Fear of Dentist killed 8 year old British girl ?

When 8-year-old Sophie Waller cracked a baby tooth eating candy, it set off a chain of events that led to her death.

Eight-year-old Sophie Waller from St Dennis, Cornwall, had an operation to remove her milk teeth after she stopped eating or speaking because of pain in one of them.

All eight of the teeth were removed so she would not have to undergo repeat operations. However she continued to refuse to eat solid food once discharged from hospital.

No kissing please, we are Indians


Look before you kiss in India. A smooch can get you in serious trouble in the world's largest democracy.
Earlier this week, a court in Delhi - ah, of all places, in the "happening" capital! - threw out the case against a young, married couple who were picked up by police allegedly for kissing near a railway station. More here

Overdrinking of soda increases risk for early kidney disease

Soda (carbonated cold drinks/colas etc) damage teeth and also cause kidney to fail.. read on
WASHINGTON, Feb. 9 (Xinhua) -- Women who drink two or more cans of soda pop per day are nearly twice as likely to show early signs of kidney disease, a recent study has found.

However, researchers did not find an elevated risk for men, or for people who drink diet soda, said lead researcher David Shoham of Loyola University Health System. The study was published in PLoSONE, a peer-reviewed journal of science and medical research published by the Public Library of Science. More here

Interalar Distance to Estimate the Combined Width of the Six Maxillary Anterior Teeth in Oral Rehabilitation Treatment: Journal of Esthetic and Rest Dent, Feb 2009

The purpose of this study was to analyze whether there is a consistent relationship between the interalar distance (IAD) and the combined mesiodistal width of the six maxillary anterior teeth.
Methods: Standardized digital photographs of 81 dentate Brazilian subjects were included in the sample. They were 37 men and 44 women (age 17 to 33). Through image processing software, the IAD and the distance between the tips of the maxillary canines were measured when viewed from the frontal aspect. Accurate casts were made to quantify the distance between the distal surfaces of the maxillary canines on a curve, by use of a flexible millimeter ruler. Nonparametric statistics were performed to analyze the results (p < style="font-weight: bold;">Results: The IAD when compared with the width of the six maxillary anterior teeth, on a straight line and on a curve, presented a ratio of 0.914 and of 1.305, respectively. The Wilcoxon test showed no significant difference between the calculated width values and the mesiodistal width measured on a curve and on a straight line (p = 0.986).
Conclusion: The IAD, when increased by 31% of its value, can suggest the circumferential distance of the six maxillary anterior teeth.
