Dental cone beam computed tomography: justification for use in planning oral implant placement

Jacobs, R. and Quirynen, M. (2014), Dental cone beam computed tomography: justification for use in planning oral implant placement. Periodontology 2000, 66: 203–213. doi: 10.1111/prd.12051


Intra-oral and panoramic radiographs are most frequently used in oral health care. Yet, the inherent nature of jaws and teeth renders three-dimensional diagnosis essential, especially in relation to oral surgery. Nowadays, this can be accomplished by dental cone beam computed tomography, which provides high-quality images at low radiation doses and low costs. Nonetheless, the effective dose ranges of cone beam computed tomography machines may easily vary from 10 to 1000 μSv, this being equivalent to two to 200 panoramic radiographs, even for similar presurgical indications. Moreover, the diagnostic image quality varies massively among available machines and parameter settings. Apart from the radiodiagnostic possibilities, dental cone beam computed tomography may offer a vast therapeutic potential, including opportunities for surgical guidance and further prosthetic rehabilitation via computer-aided design/computer-aided manufacturing solutions. These additional options may definitely explain part of the success of cone beam computed tomography for oral implant placement. In conclusion, dental cone beam computed tomography imaging could be justified for oral implant-related diagnosis, planning and transfer to surgical and further prosthetic treatment, but guidelines for justification and cone beam computed tomography optimization remain mandatory.

Los Angeles Dental Students take Carestream Dental Equipment to a Community that Needs it Most

ATLANTA—According to the World Health Organization, Honduras has only two dentists per 10,000 people; the United States has eight times that number. To address this need for dental professionals, Carestream Dental recently loaned an RVG intraoral digital imaging system to members of the American Student Dental Association (ASDA) Philanthropy Committee, comprised of University of California, Los Angeles dental students, for their 2014 dental mission trips to Guaimaca, Honduras.
Four fourth year dental students; three third year dental students; four pre-dental students; and two UCLA faculty—one periodontist and one prosthodontist—traveled to Guaimaca, June 14-26, 2014. The students will take the RVG sensor back to Guiamaca for two more dental mission trips in September.
“We first met these dedicated students at a student fair last fall and knew Carestream Dental could contribute to their work in Honduras,” Colby Ledbetter, regional director, Carestream Dental, said. “We were able to work out a loan of the equipment and now the students will be able to use the sensor for the rest of the year on each trip.”
Though the ASDA Philanthropy Committee has provided oral health instruction, cleanings, amalgam and composite restorations and extractions to the community in Guaimaca since 2010, this year was the first time the dental students had an intraoral sensor available to them.
“Having the digital X-ray made a difference between ‘mission-level’ care and professional-level care, without spending more than an extra 10 minutes per patient for X-rays while they were waiting,” Shane Chou, co-chair of the ASDA Philanthropy Committee, said. 
The sensor also aided in more accurate diagnoses, such as determining whether a simple extraction or restoration was necessary.
The RVG sensor features excellent image resolution, and the size 2 sensor, which Carestream Dental loaned to the dental students, is perfect for bitewing radiographs. Featuring rounded sensor corners and a rear-entry cable, the dental students were able to place the sensor quickly and easily, thus improving patient comfort
“The biggest difference the digital sensor made was our ability to do endodontic procedures,” Chou said. “We did a total of four endodontic cases, all anterior teeth, because we could restore them.”
In total, the students conducted 250 procedures, providing $15,000 worth of dental work, during their week in Honduras.
“We’re always thrilled to hear how Carestream Dental equipment changes people’s lives,” Marc Gordon, general manager, U.S. equipment and software, Carestream Dental, said. “Not only are these students gaining valuable experience, they’re taking professional-level dental care to a community that would otherwise go without, and that’s what’s truly important.”

The Tooth Decay Index

Did you know that starchy, refined carbohydrates–foods like chip, bread, pasta, and crackers — can be as harmful to teeth as candy? What about how important saliva is to tooth health? Find out how with out tooth decay index!
You are what you eat, your teeth are too.

The pH Scale affects bad breath, tooth decay

Common pH values:
Battery acid 1.0
Gastric acid 2.0

Tooth Decay Index

[#ranking] Components:
S = Sugary
A = Acidic
St = Starchy
ick = Sticky
M = Mouth Drying 1 = Best
40 = Worst
40 -Soft Drinks (S, A, ick, M) Soft drinks are probably the worst food for your teeth. They can cause dental erosion in short periods of time, are extremely sugary and have both phosphoric and citric acid.
39 -Sugar Free Soft Drinks (A, ick, M) People think that sugar-free soft drinks are better for your teeth. But they still have phosphoric and citric acid, and syrups stick to your teeth.
38 -Sugary Candies (S, ick)
37 -Chewy Candies (S, ick)
36 -Sweets that get stuck in your mouth (S, ick)
35 -Dried fruit (M) Dried fruits are sweet and sticky, They also are packed with non-soluble cellulose fiber which binds and traps sugars on teeth.
34 -Lemons (A, M) The high acidity in lemons can cause dental erosion. Compounding with acid reflux, and the ability to dry your mouth, lemons and lemon juice are harmful to dental health.
33 -Other citrus fruits (A,M)
32 -Pickles (A,M)
31 -Tomatoes (A)
30 -Pizza (A, St)
29 -Crackers (St,M) Starchy foods made from white flour are simple carbs that linger in your mouth and produce simple sugars. These feed bacteria causing tooth decay and bad breath.
28 -Coffee (A,M) Coffee stains teeth more than tobacco. With high acidity, and the ability to stick to your teeth, attracting food and bacteria particles, coffee is bad for dental health.
27 -Red and White Wine (M)
26 -Fruit juice (A,M,S)Fruit juices are sugary (often artificially), and many are more acidic than vinegar when consumed excessively. This wears down teeth and feeds bacteria in the mouth.
25 -Honey (S,M)
24 -White/Instant/Polished Rice (St)
23 -Beer (A, S, M,)
22 -Ketchup (St, M, S)Ketchup contains high levels of sugar, high fructose corn syrup, and acid. This allows ketchup to stick to teeth, erode enamel, and feed bacteria.
21-Pasta (St)

The Good Guys

20 -Raisins-Raisins contain fructose and glucose, which aren’t the most harmful types of sugar. They also contain phytochemicals that help fight the bacteria in your mouth.
19 -Cranberries Cranberries contain compounds that reduce bacteria’s production of acid by up to 70%.
18 -Apples
17 -Carrots/Cucumbers
16 -Plain Yogurt
15 -Cheese
14 -Milk -The sugar in milk is lactose, which is the least damaging to teeth. Plus milk and dairy products are full of calcium.
13 -Beans
12 -Leafy Greens -Leafy greens, and other foods that force you to chew a lot literally scrub your teeth. They are rich in phytochemicals that fight bacteria, and some greens (collards, kale) are high in calcium.
11 -Spinach -Cleanses the mouth and scrubs teeth.
10 -Green and Black Teas -Combats bacteria
9 -Xylitol (sugarless chewing gum) -Xylitol is a natural sweetener derived from fibrous parts of plants. It doesn’t break down like sugar and can help keep a neutral pH level in your mouth. Xylitol also prevents bacteria from sticking to teeth.
8 -Chicken – Strengthens teeth
7 -Beef – Strengthens teeth.
6 -Walnuts -Walnuts are a powerhouse filled with fiber, folic acid, iron, thiamine, magnesium, niacin, vitamin E, vitamin B6, potassium and zinc.
5 -Almonds -Scrubs teeth and strengthens teeth.
4 -Cashews -Scrubs teeth and strengthens teeth.
3 Eggs -Eggs are high in phosphorus, a chemical needed for the formation of tooth enamel.
2- Fatty fish like Salmon Salmon is high in phosphorus and Vitamin D, which allows your body to absorb Calcium.
1-Water – Water is the primary component of saliva, and helps both teeth and gums to repair. It is also a final rinsing agent for foods and sugary drinks.
Saliva is important for dental health because of saliva’s ability to wash away bacteria, cleanse teeth, prevent bad breath, and help gums and tooth enamel grow.

Do’s and Dont’s for Tooth Health:

Crunch ice or popcorn
Don’t “swish” around acidic drinks
Don’t vigorously brush after acidic foods
Use a straw for acidic/sweet drinks
Use water as mouthwash

Immediate placement and loading of maxillary single-tooth implants: a 3-year prospective study of marginal bone level.

J Contemp Dent Pract. 2014 Mar 1;15(2):202-8.



The purpose of this study was to evaluate marginal bone level around single-tooth implants placed in anterior maxilla and immediately restored.


Twenty implants were placed in 20 patients (8 men and 12 women) that were selected for this study. Following atraumatic non-surgical extraction of tooth, all patients immediately received implants and the defnitive prefabricated abutment was placed. Implant position was transferred to the scanning unit of the CAD/CAM system using prefabricated surgical guide. Temporary crowns were immediately fabricated and cemented. Eight weeks later final crowns were luted. Outcome assessment as implant survival and level of marginal bone radiographic evaluations were performed at 8 weeks, 1 and 3 years time period after loading.


All implants placed osseointegrated successfully after 3 years of functional loading. The mean marginal bone loss was 0.16 mm (SD, 0.167 mm), 0.275 mm (SD, 0.171 mm) and 0.265 mm (SD, 0.171 mm) at 8 weeks, 1 and 3 years time period respectively. Four out of the 20 implants showed no bone loss.


Immediate loading technique using the final abutment directly eliminated the need for a second stage surgery and prevented interruption of soft and hard tissue at implant neck, which resulted in better soft tissue response and reduced marginal bone loss. Clinical signifcance: Immediately loaded implants, in fresh extraction sockets by insertion of a provisional restoration on the titanium abutment without any later manipulation, helped to protect the initially forming blood clot and presented a template for soft tissue contouring that resulted in signifcant reduction of marginal bone resorption and maintenance of soft tissue architecture.

The Influence of Acidogenic Challenge on Enamel Microhardness around Restorations

Journal of Dentistry for Children, Volume 81, Number 2, May/August 2014, pp. 67-71(5)


Purpose: The purpose of this study was to evaluate the influence of acidogenic challenge on microhardness of enamel adjacent to adhesive restorations in primary and permanent teeth.

Methods: Occlusal cavities were prepared and immediately restored with two adhesive systems and a composite resin. The specimens were divided into eight groups, according to the type of tooth (primary or permanent), adhesive system (etch-and-rinse or self-etching), and treatment (control or acidogenic challenge). The cariogenic challenge groups were submitted to pH cycling for 10 days. The teeth were prepared for a cross-section microhardness test. Analysis of variance and Tukey's post hoc test were used to analyze the data (α=5 percent).

Results: The adhesive systems did not influence the enamel microhardness (P<.27). Primary teeth were more susceptible to acidogenic challenge (P=.004). The microhardness values for control groups were statistically similar at different indentation depths (P>.05); however, in the acidogenic challenge groups, lower microhardness values were observed in superficial measurements (P<.05).

Conclusions: Acidogenic challenge negatively influenced the microhardness of the enamel surface adjacent to adhesive restorations. Mineral loss was higher in primary teeth and on the enamel surface.
