Can Commercial Orange Juice Destroy Baby's Teeth ?

Can Commercial Orange Juice Destroy Baby's Teeth ?

With the boom in health care products, many baby heath drinks have been launched in the market. The analysis showed that the pH of these drinks range from 3.5 to 4.0. In an experiment the authors found that 3.77 to 8.10 microns of enamel was destroyed in 1 hr. It is concluded that commercially available baby heath drinks pose a definite risk of excessive enamel erosion on continuous and long term use.

In Vitro Toxic Potential Of Compomers

Three different compomers were tested for their toxicity after applying different types of curing lights.The study concluded that the compomers are potentially toxic to human pulp. Type of light curing unit may also affect the degree of compomers toxicity. These results were obtained by adding compomers to human pulp fibroblast cultures.

Is PALS an Effective Child Management Technique ?

Child management in dental clinics can be done by various methods. PALS stands for passivity to activity through live symbolics. A study conducted on 5-10 year old dental patients showed that PALS is ineffective in modifying a child behaviour and response to interventional dental treatment.

Can Probiotics Bacteria Colonize The Mouth After Taking Such Products ?

Probiotics are in trend these days. Microbiologically probiotics are products fortified with Lactobacilus reuteri ATCC 55730. As documented they colonize the deuodenum and ilium of the subject and provide enhanced immunity. L. reuteri also induces a significantly higher number of CD4positive T-lymphocytes. The L. reuteri dimish in number very soon from the oral cavity and there is no danger of their colonization in the oral habitat.

Device To Administer Painless Anesthesia

It is very common to face difficulties in dental practice due the fear of pain during anethesia. Especially in pediatric patients it becomes too difficult to manage. This new device can deliver painless anesthesia to your pediatric patients. It is QuickSleeper (TM). It has an electronically controlled system that is capable of delivering intraosseus anesthsia without any thrust from the operators hand. Just place it near the required area and it automated system does the rest.

Interesting Facts About Bone Grafting

Can Bovine Spongiform Encephalopathy Affect Patients With Bone Grafts Of Bovine Origin ?

Bovine bone is one of the most popular xenogenic bone substitute used for regenerative procedures. Several patients and dentists are concerned over the transmission of cattle diseases to the human recipient. Risk assessment studies by A. Sogal and A.J. Tofe concludes that "Based on the risk analysis, it is evident that the risk of BSE infection from BGS is several orders of magnitude less than that posed by the risk of death related to, lightning, tornadoes, or similar remote events. However, this low risk can only be maintained as long as an effective and active risk management program is implemented in operations that involve processing xenogenic tissue for human use." Journal of Periodontology September 1999, Vol. 70, No. 9, Pages 1053-1063 , DOI 10.1902/jop.1999.70.9.1053

What Is The Thickness Of Cortical Plate ?

The average thickness of buccal cortical plate in dentulous mandible is 2.76 mm (± 0.13 mm) while in edentulous mandible is 2.52 mm (± 0.32 mm). The study was performed on cadevors.All these cases exposed the inferior alveolar nerve. So the safer side would be to keep the thickness below the mentioned data.

Can A Previous Donor Site Be Used Again For Bone Harvesting ?

5 patients underwent bone grafting from symphyseal region. 5 months later there was a need to harvest more bone for implant placement. As the are showed new bone formation in the previous site, once again the bone was harvested from the same area, months later the implants were placed. Both the areas, the donor site and implants site showed proper healing. It can be concluded that bone can be harvested once again from the previous donor site.

Novel Technique Of Bone Harvesting For Implant Placement

A new technique has been devised by Kyung-Gyun Hwang, Kwang-Sup Shim, Seung-Min Yang,and Chang-Joo Park that utilizes only the cortical bone of the ramus. This technique overcomes the drawbacks associated with conventional techniques e.g. postoperative pain and swelling to impaired inferior alveolar nerve function. The chances of inferior alveolar nerve damage are abolished because the strategic choice of the site. It is a safe, predictable and reproducible technique for bone harvesting.

Recent Advances In Implants Every Dentist Ought To Know

How To Manage Papillary Deficiencies Between Implants ?

A number of cases show deficiency of papilla in the interdental area, which may be between implants, or an implant and teeth. This can impose critical esthetic problem for the patient as well as the dentist. The most recent advancement in this field is the injection of hylauronic acid commercially availabel as Restylane (TM). The effect lasts for 6-24 months after which a new dose is required. (1)

Maxillary Sinus Floor Augmentation

Recently Calcium sulfate has been used for maxillary sinus floor augmentation. Calcium sulfate placement showed significant maxillary sinus bone formation. Placement of implants after this procedure led to successful implant placement and loading. (2)

Can Bone Regeneration Occur In Uncontrolled Diabetic Patients ?

Diabetic Patients reporting for implant placement with angular bone loss require bone regenerative techniques before proceeding with implants. Experiments on rats with artificially created bone defects and uncontrolled, drug induced diabetes were carried out. The results were encouraging as it showed significant de novo bone formation via GBR even in uncontrolled diabetics. (3)

Is Osseointegration Possible In Diabetics ?
A review study of MEDLINE/PubMed articles published from 1982 up to and including July 2009 were carried out by researchers. 33 articles were selected. It was concluded that proper glycemic control and HbAA1c in normal range will lead to successful implant osseointegration in diabetics similar to normal individuals. (4)

How Do Implants Fare In Periapically Infected Bone?
Placement of implants in fresh extraction sockets has been taking place for long. How ever a question was intriguing, that whether an immediate implant can survive if placed in an extraction socket of a periapically infected tooth. A 24 months follow up of patients showed 100% success rate in implants placed in the sockets of teeth previously infected at the periapical region. (5)
