Hello,
These Questionnaires are extensively used in both clinical and research settings. Berlin questionnaire has more questions and assists the patient snoring. But one disadvantage is that it only categorise patients to high or low risk. While STOP-bang questionnaire is shorter but it categorise patients to high , medium and low risk.
We are conducting a cross sectional study to find the prevalence of possible obstructive sleep apnea among dental patients based on sleep apnea questionnaire and oral findings (airway, tongue size...).
My question is: Which one of these questionnaires is recommended for such study?
Could fall down be the most common etiology of mandibular fractures especially in countries with rapid architectural urbanization? are there published articles or researches which support or have this result?
A research assistant told me that the mandibular anterior region is a safe region for implant placement despite the presence of mandibular incisive canal because of the nerve atrophies after the extraction of teeth in this region. But what if we put a single implant between some other anterior teeth or if we take a graft from anterior bone in the presence of the teeth?
Just Imagine... A Short Tribute to Nelson Mandela, the guest editorial by C Peter Owen (Int J Prosthodont 2010;23(6):491) is an unique one and something that's rare in the pages of a specialty journal. This impassioned piece is written on the eve of the 92nd birthday of Nelson Mandela and is adeptly connected to prosthodontics and how the industry driven hype can mire our ultimate goal as caring professionals. Check my blog post for details.

A 74 year old gentleman with severe anterior deepbite and generalised attrition, with severely attrited mandibular anterior teeth insisting on full mouth rehabilitation. Bite (vertical dimension) to be raised minimum by 5mm-6mm. Please give your opinions / suggestions/ experiences of such cases with possible prognostic outcomes. Thanks & regards
Literature revealed that this is a rare tumor of jaw. Prognosis are not very well described. Looking forward for any clinician/surgeon/researcher to share their experience in managing this tumor in an adult patient.
The partial impacted or fully impacted third molar significantly increase the incidence of mandibular angle fractures and decrease the incidence of condylar fractures. Due to the potentially challenges to the surgeons also more serious complications associated with condylar fracture, should the clinicians carefully consider the decision of mandibular third molar extraction?
How about the opinion that said, "the early removal of 3M is suggested to prevent the risks inherent in maintaining these impacted teeth as well as to limit future surgical risk and difficulties"?
How can we calculate the benefits and risks?
Intracapsular mandibular condylar fracture displaced more than 5 mm and more than 30 angulation.Is it always necessary to open TMJ capsule? Please give your idea. The patient may visit early, or it may be delayed case.Thank you.
In this case two ducts come out of the anterior border of Parotid gland, unite with each other to form a single duct. This duct resumbles english letter Y, So we named it as Y shaped parotid duct. A sound Anatomical knowledge of this duct is important to decrease post operative complications after parotid surgeries, as leakage of secretion from parotid duct may lead to delayed wound healing.

3. Measures to control bleeding & promote clot formation.
The general consensus in the field of head and neck oncology states that appropriate initial management of these tumors is surgical extirpation with adjuvant treatment. There is controversy in the field regarding the appropriateness of elective lymph node dissection.For maxillary alveolus and hard palate tumors, it has traditionally been believed that the risk of nodal metastases is not high enough to warrant elective lymph node dissection.In the majority of cases, in the absence of clinical evidence of cervical nodal metastases,neck dissection is generally not recommended, independent of the size or depth.
Dear all, deficient ridges are among the most challenging situations in the dental clinic; it is considered as a critical size defect. Therefore, it is of great value to find out a successful and predictable line of treatment to such a problem.
After radical neck dissection, I saw a few patients developing saliva collection under the flap, So, how could the case be managed?
During treatment of KCOT using either enucleation with or without ajuvant therapy or marsupialization with or without residual cystectomy, some authors advocate that excision of the overlying mucosa is necessary to eliminate epithelial and micro cysts with subsequent reducing recurrence?
Presurgically, as kcot is a benign tumor , we have to manage it drastically.are there reliable diagnostic features ( clinical, radiogrophic ) particularly in dentate patients?
The lower third molar surgery is the most common surgery performed by Oral and Maxillofacial Surgery. There are various method to do bone guttering or tooth sectioning to facilitate tooth delivery. The piezoelectric surgical technique is a promising method when compared to rotary burs. Unfortunately, there was a sold evidence to support the superiority of this promising technique over the rotary instruments.Thus , We have this evidence based on papers ( a systematic review and meta analysis) to resolve the issue concerning this matter. I am asking here to allow an expert Doctors and my colleagues to discuss this very interesting topic .

The surgical approach to cystic lesions of the jaws is either marsupialization or enucleation. The treatment of choice is dependent on the size and localization of the lesion, the bone integrity of the cystic wall and its proximity to vital structures.
The technique of marsupialization, or Partsch’s technique, consists of removing a window from the lesion and suturing the surrounding mucoperiosteum to the margins of the cyst wall. The ensuing cavity is filled with gauze, which is removed after seven to ten days. If necessary, the gauze is changed during this period. This procedure aims to reduce the size of the cyst: opening the cyst eliminates its osmotic pressure and bone apposition gradually occurs at the site previously occupied by the epithelial covering of the cyst. These procedures can be used as a single treatment for a cyst or as preliminary treatment for subsequent enucleation.
