Questions related to Periodontics and Oral Pathology
The systemic antioxidant therapy is one of the therapeutic options for oral mucosal lesions. In Localized delivery of antioxidant molecules to the oral mucosal lesion, will the oral mucosal cells uptake/absorb the antioxidant molecules? Will the antioxidant molecules perform their action when delivered locally? Which route of delivery (systemic/local) of antioxidant molecules can have better activity?
I have noticed gingival and periodontal ligament fibroblasts have differing morphologies when cultured with MTA.
The apical coronal or coronal apico is known, the decision depends on the presence of necrosis or irreversible pulpitis or acute periapical abscess.
Antibiotic resistant endodontic infection is a common finding in failed root canal treated tooth with history of long term medication.
As a part of a research proposal to the Indo-Norwegian collaborative research, we would like to have a norwegian team to do a part of this project.
Interested Norwegian researchers kindly contact.
We are aware of the discoloration of teeth by tetracycline administered during pregnancy and in young children. My question is, does tetracycline/doxycycline mouthrinse cause tooth discoloration?Any scientific studies/evidence on this please???
Just got a question concerning the total aplasia (primary + permanent) in the 4th quadrant of a 4-y-old boy. No more info available at the moment.
Don't know what to recommend.
1. Transplantation: seems from the radiograph that there is no bone as alveolar process. Would mean lateralisation of nerve. Never heared of such surgery in such a young patient. Any information???
2. Tx 2: Never done such surgery in that age. Earliest tx was a primary canine in a 6-y-old to replace a lost incisor, earliest tx of a pm to replace an aplastic pm was at about 11y.
3. Tx 3: Never done that in cases like this: Will there be the development of an alveolar process or will it stay as lower-jaw basis? I guess it should develop, at least in parts, but I don't know for sure...
4. Indication to treat: Definitely yes, I have the impression of muscular hypertrophy on the left. But when? Still some time, or tomorrow?
5. Indication 2: Any other treatment? Temporary? Definitive?
Dear ResearchGate Community,
I'm currently working on the implementation of the Ligature-Induced model of Periodontitis in Rats (Winstar - Sprague Dawley). Yesterday I had my first try... however I discovered rat molars are very distal and difficult to access. I tried to use a 4-0 silk suture (3/8 circle) but found it impossible to access!
Does someone has experience on this model? I need advice or guidance on how to reach the molars.
With best of Regards,
Ps. Sorry for my english, sadly I am not a native speaker.
The current imaging method of choice is conventional dental radiography. Needed information regarding impacted teeth cannot be obtained adequately by lower dose conventional (traditional) radiography. Should the indication to use cbct be emphasized?
There are various methods for the dental age assessment like the Nolla's, Demirjian's, Willem's etc. Nolla's method seems to be an easy method to assess the dental age of any given population. What are the merits and demerits of using Nolla's method for dental age assessment?
Is there any published literature which gives clear guidelines on when resective or regenerative periodontal surgery should be done ?
Cases of aggressive periodontitis are not plenty in number.
How to carry out a reliability study for an index on aggressive periodontitis?
Does Space analysis of TMJ by CBCT is an accurate method for discrimination between patients with clicking and normal patients?
I would like to know if any on e knows if there is anything out there in the market place that will help a dentist with this problem when using an air abrasion unit in clinical practice.
Does it aid the speed of recovery? Long-term vs short-term benefits?
Is it as effective in extraction socket as using of particulate graft material in socket preservation?
Itchy gums and periodontitis? What is the pathogenesis of the itchiness of the gums that periodontal patients sometimes complain about?
I am particularly concerned with the chance of brittle enamel getting chipped off while doing US scaling.
Also, noticed excessive sensitivity to cold water and air in these patients. How to overcome the stated problems.
What are the most recent host modulation therapies indicated in treatment of aggressive periodontitis? I am working on the anti-oxidant role of host modulation therapy.
A 31-year-old male patient with exophytic mass growing out from his left buccal mucosa, measured 3X2 cm. Incisional biopsy was taken from periphery and it was proved as SCC. After the incisional biopsy (after 14 days) the patient came with progressively enlarged tumor mass from the biopsy site.
Evidence based dentistry started 20 years ago (1). Most Cochrane Systematic Reviews still end with the conclusion that recommendations for clinical practice cannot be made based only on the results of these trials and that more randomised controlled trials are needed to elucidate the interventions for treating a certain kind of malocclusion. Turning the Cochrane reviews into a tool that is more relevant in clinical practice will require implementation of a methodology allowing inclusion of non-RCTs while controlling for possible bias.(2)

I look for any kind of academic institution worldwide to collaborate in dental/periodontal research or lecturing/teaching.
Topics: periodontology / implantology / halitosis / lasers in dentistry.

A patient presented to us with multiple keratocysts. Work-up did not show features of Gorlin-Goltz syndrome. Before being diagnosed as nonsyndromic or Gorlin-Goltz with partial expression, I need to rule out other possible syndromes. Do you know such? or an article listing them. I couldn't find in PubMed.
Are there any dental consultations required before commencing chemo?
Any fluoride treatment during the course of chemo and later?
As invasive as it is, this technique, with its variants, seems interesting and promising. I would much appreciate learning from your critical opinions and experience.
I attach one article and list here others, equally easily available on the net.

Aggressive periodontitis attacks people at early age of life and causes extensive bone loss which might lead to early loss of dentition, early detection of patients at high risk to be attacked by this type of periodontitis will help them a lot to be involved in a strict professional and personal preventive program thus minimize the periodontal damage to a large extent .I wonder if any one has ideas about any chairside methods for early detection of risk factors and those who are at a high risk for developing this kind of periodontitis?
Looking for association of DAS 21 and periodontal status, also looking in to role of stress in Hbac1c levels, DAS 21 and periodontal status
I am conducting a research about Oral health related quality of life by using OHIP-14. One of my variable for conceptual framework is Knowledge,attitude and practice. I am having trouble with the literature part to support which model do I base on for the KAP part. Is there any model that support KAP and oral health related quality of life? I need to put something to support my variable for my literature review part. If anyone can help, please do. Thank you
Is there any scientific data or published article to show that cases of aggressive periodontal disease with positive family history have or are at more risk for increased periodontal breakdown?
An 11- year- old boy presented to the dental clinic with his father, complaining of poor esthetics and delaying of eruption of teeth. Examination revealed a suspicion of amelogenesis imperfecta ( clinically & radiographically). Teeth present: 11, 21, 31, 16, 26, 36, 46, all primary molars and canines and partially erupted 12,22, 42. Patient has also angle, class III. Outline the treatment plan for such a case.
In the treatment of gingival recession around lower incisors by applying free connective tissue graft along the area of recession, how it is possible to pull the alveolar mucosal flap from the vestibule and inner mucosa of lower lip with the purpose of covering the connective tissue graft over the gingival recession?
I have been using 910nm diode laser for treating the rct failure cases with periapical abscess forming a sinus tract into the sulcus, and I am seeing a very good prognosis.
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?
Does anyone have some experience in staining macrophage in periodontal tissue, especially in periodontally-infected (i.e., periodontitis) tissue in mice? 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?
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?
I am using 2% curcumin gel to treat experimental periodontitis. I wanted to assess the acute toxicity and chronic toxicity of this gel used to apply subgingivally in rat model. Please let me know the answer.
I am working on the effect of topical curcumin on ligature induced periodontitis in wistar albino rats. We have used a gel base which delivers curcumin for 24-48 hours. We confirmed the duration of activity using paw edema method, but the drug release rate is only 60% when the gel is applied and inflammation is induced using 0.1% carrageenan. We have treated 1 group with the same gel.
Recently, I have observed in my clinical practice a re-swelling of infected canal after antiseptic dressing. Sometime the tooth become mobile and extruded. Please suggest the possible solution.
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?
Discussion is welcome keeping in mind the pros and cons of these mouthwashes. If we recommend it, do we monitor the patient compliance regarding its usage.
Treacher Collins syndrome (TCS), also known as Treacher Collins–Franceschetti syndrome, or mandibulofacial dysostosis is a rare autosomal dominant congenital disorder characterized by craniofacial deformities, such as absent cheekbones. Treacher Collins syndrome is found in about 1 in 50,000 births. The typical physical features include downward slanting eyes, micrognathia (a small lower jaw), conductive hearing loss, underdeveloped zygoma, drooping part of the lateral lower eyelids, and malformed or absent ears.
What do you think the prognosis will be in case of endo ttt with custom made post & crown later (note the age of the patient)?
I'd like to know the experience of the researchers about the use, efficacy, safety and side effects of this therapy for large CGCG.
I've read several periodontal articles written in the '90s that mention pulpal and gingival periodontitis. Are these titles alternative terms for the pathological types referred to as periapical and planar (AC) periodontitis in more recent work? Thanks!
