- Amit Agrawal added an answer:Does it make sense to use the Platelet-derived in dentistry today?I'm writing a review and I just want to test the opinion of the network.When we are talking about PRP, one important thing to consider is that how much RICH the plasma should be? Say at least 3 times and original platelet concentrate in the blood. But how many of the articles have actually counted pre and post platelet conc. and then supported the results they got.
In a small in-vitro study done few years back at GDC Nagpur, India. Out of 10 samples of PRP, only 2 had more platelets in PRP, 3 had equal amount, and 5 samples actually had lesser concentration of platelet than the patients blood levels. Unbelievable right? This occurs because the procedure of obtaining PRP is followed differently at every setup, the technique is skill demanding and at the end rought handling of platelets can damage them reducing the actual potential of PRP.
PRF, comparatively is much easier to obtain. But can any body tell me how to count platelet conc. in PRF?Following
- Chiara Baroni added an answer:Why is diode laser irradiation used in intervals with multiple doses of laser?In a number of articles, diode laser is used along with scaling and root planing in moderate periodontitis cases. After the first diode laser application, it is used in intervals- on the 4th,7th,9th and 11th day (a total of 4 or 5 applications of diode laser in Periodontal pockets). Is there any standard criteria for using diode laser in intervals with multiple doses of laser?Does any of you have experience in diode laser remineralisation of hypomineralised enamel?May be using fluoride as an intermediate?How many applications would you suggest?Following
- Steven E Eckert added an answer:Is there any scientific evidence on the success of Laser-assisted new attachment procedure (the LANAP protocol) in periodontal surgical therapy?.The American dental Association has provided a statement on the use of lasers and dentistry. If you go to ADA.org and then search this topic you will find a pretty well thought out response.
Here is the section related to the LANAP protocol:
Laser-Assisted New Attachment Procedure
A 2007 publication compared the probing depth, attachment gain, and type of attachment from traditional mechanical therapy of advanced chronic periodontitis vs. traditional mechanical therapy that included two intrasulcular applications of Nd: YAG; one aimed at removing the sulcular epithelium and another said to “seal” the pocket.2 In this study, histology was performed on 6 pairs of single-rooted teeth at 3 months. Laser-treated pockets tended to show greater probing depth reductions and clinical attachment gains than non-lased pockets. Based on measurements from notches placed in periodontally involved root surfaces before treatment, lased teeth showed evidence of new cementum while 5 of the 6 control teeth showed a long junctional epithelial attachment. This study concluded that the Laser Assisted New Attachment ProcedureTM (LANAP) can be associated with cementum-mediated new connective-tissue attachment and apparent periodontal regeneration of diseased root surfaces in humans.
Although the Council is optimistic regarding the potential for lasers to enhance effectiveness in treating periodontitis, dentists should note that this study provides no more than pilot validation for this treatment concept. The study was not blinded, and the sample size was small thereby limiting extrapolation of the results to the general population. Further, pre-treatment notches in the teeth were difficult to place, hard to know exactly where they were placed and are difficult to clearly detect on histological specimens. Moreover, the advanced periodontal destruction initially present in these 6 test teeth make it difficult to extrapolate these results to cases of early and moderate chronic periodontitis, where the anatomic environment, laser energy distribution and clinical outcome may differ substantially. It is also unclear what laser-based “sealing” of a treated periodontal sulcus is and, if real, what benefits it might provide. Additional clinical data from properly designed clinical trials with adequate sample sizes are still required before it can be known to what extent LANAP is safe and effective across the spectrum of patients with chronic periodontitis. The Council therefore cautions clinicians to weigh the available evidence for LANAP when considering the options available for treatment of the periodontal diseases.
So my interpretation, using this statement from the American dental Association is that this procedure may have some potential but there is certainly no definitive hard scientific evidence to show that it is anything more than another way to address a problem.Following
- Amit Agrawal added an answer:Does anyone have information on drug induced gingival overgrowth in antihypertensive therapy?Identification of this problem as early as possible is very important in management. How do I do it?
There are many new antihypertensive drugs being used. Some of these might have a similar effect? Are there any research papers?Nifidipine, Amlodipine, Cyclosporine all are known to lead gingival overgrowth. But suppose a patient is taking all three drugs simultaneously, then how to proceed.Following

Growing attention is paying on macrophage in periodontitis. However, it seems too few macrophages exist in periodontitis, let alone in the tiny gingiva in mice. If I hope to immunostain macrophages in paraffin-embedding jaw from mice, what are the notes during decalcification, tissue processing and immunohistochemistry?Dear Antonius Bronckers, Thank you for your so kind advice in detail ! I'm itching to try the classical TRAP staining method in periodontal tissue. Could you give me a TRAP protocol for parraffin-embedding jaw from mice, since very few articles have descripted this condition in detail? Your suggestions on distinguishing macrophage from osteoclast in periodontal tissue is noticeable and very useful. But I wonder if the TRAP kit will stain any cells other than macrophage and osteoclast, e.g., if any, mast cell or plasma cell? As you said, osteoclast is multicleated (>3 nuleus could be seen as a threshold ) which might be excluded to count macrophage in periodontal tissue? Strictly speaking, there are no specific but more representative markers for macrophage, such as F4/80 and CD68, with which I would try. According to your experience, how many macrophages-like cells could be stained in subepithelial connective tissue?Following

- Nathan Alexander Moreau added an answer:What is the frequency we have malignant degeneration in odontogenic Cysts? How to do the right diagnosis?Odontogenic Cysts/CancerAccording to recent scientific literature, it seems that the occurence of a primary intra-osseous squamous cell carcinoma arising from degenerated odontogenic cysts is around 0.3 to 3% of cases. (Jain et al. 2013)
This malignant degeneration seems to occur more frequently in large old cysts, which have gone untreated for several years.
It seems that the only way to ensure proper diagnosis is through systematic histopathological analysis of "suspect" cysts. On that matter, follow up is paramount.Following

- Aaro Turunen added an answer:Which is the most common benign tumor of the oral cavity?Between fibroma, lipoma, hemangioma, and lymphangioma.Out of those 4 I agree with the fibroma being most common, however I also agree with Dr. Subramanyam - it arises as a reactive hyperplasia and actually if we want to be slightly cheeky, I´d say lipoma is the most common actual tumor from those four presented by Dr. Mohammed because there are many misdiagnosed vascular malformations labeled as "hemangioma" that are not actual monoclonal tumours :)
Dr Gianninis answer is also excellent: in order to diagnose disorders of certain parts of the body we must know what cells are present there - I was told a few weeks ago that upon showing a clinical and a histopathologic picture of an oral dysplasia to a student and asking what can be seen there, the student answered that there is cartilage present in the sample. Now, if this had been true from an oral sample it would almost certainly indicate a sarcoma of some sort since cartilage should not be found in the oral cavity at all and it would need to have come from somewhere else!Following

- George Michelinakis added an answer:Can anyone give me insight on the risk of developing osteonecrosis of the jaw in dental implant patients taking oral bisphosphonates?I’m aware that a higher risk is observed in patients receiving bisphosphonates by IV (Gen Dent. 2010 Nov-Dec;58(6):484-92), but am curious to know specifically if recent studies have demonstrated a relationship between oral bisphosphonates, implants and osteonecrosis of the jaw. Is there a risk/relationship? And should implant patients taking oral BPs be informed of this possible additional risk?Hi.
There is ongoing research on the issue of implant placement in patients receiving bisphosphonate treatment. The current data is rather weak, short-termed and further well-designed studies need to be conducted.
Nevertheless, as mentioned above, for patients taking the IV form, implant placement should be avoided.
For patients taking oral bisphosphonates, there seems to be a 3 year continuous treatment threshold beyond which, implant placement is not contra-indicated but should be performed under strict aseptic conditions, minimal trauma to the bone, suturing and two-stage procedure and antibiotic cover. CTX testing is not conclusive according to present data. For patients receiving oral bisphosphonates for less than 3 years, implant placement should be carried out as normal.
Hope it helped.Following

don't know whether there you got an answer to your question or not.
This your question should have been presented in Topic STAINING rather than this one (Periodontics and Oral Pathology), I guess.
Just to be short here: the requested water:powder ratio will depend on the mol-weight of the dye you use.... so you should at least define here (to the forum) which dye you intend(ed>) to use ;-): There are several forms of the dye (and therefore also different Mol-weights = g/mol) e.g. Rhodamine B (MW 442, water solubility: 2%; 1,8% in ethanol), Rhodamine 6G (MW= g/mol 479.02, water solubility: 20 g/l (25 °C) ), Sigma-Rhodamine 123 (MW 380.82, water solubility: at least 0.1 % (25 °C)), NHS-Rhodamine (W: 528)…(sources: Techn. Data Sheets, MSDS, and partially also CONN’s Biol.Stains,10th Ed, Handbook of Dyes, Stains and Fluorochromes for Use in Biology & Medicine (Horobin RW & Kiernan JA,,Eds) BIOS Scientifuic Publishers,Oxford UK, 2002,ISBN 1 85996 099 5).
I assume you can calculate 0.01mM of Rhodamine in g/L for your purposes. In water there should be sufficient solubility. If you have problems with dissolution, try ultrasonic treatment or heat water to 50-60°C, stir thoroughly(at least 3-4 hrs). Best regards and good luck, Wolfgang MUSS, SALZBURG, AUSTRIAFollowing
