    Thus, the former term, “acute necrotising ulcerative gingivitis” (ANUG) is summed up in necrotising gingivitis (NG(
    NG is a relatively rare disease and is generally described as existing in young adults between the ages of 18 and 30 years.
    It tends to emerge more frequently when the patient is under conditions of both physical and psychological stress.
    The disease is characterized by pain, bleeding and papillary necrosis with tendency to relapse

They do not displace teeth or resorb roots, and the lamina dura is left intact. They may range from very small (<1 cm) to very large (involving most of the mandible). They tend to occur above the inferior alveolar canal

    b-dentigerous cyct
    c- Odontogenic keratocyst
    Ameloblastomas, also known as adamantinoma, are the most common odontogenic tumor (35%). They are benign, locally aggressive neoplasms arising from ameloblasts, which typically occur at the angle of the mandible and are often associated with an unerupted tooth and must therefore be differentiated from a dentigerous cyst which will be centered around the crown. When in the maxilla (less common) they are located in the premolar region, and can extend up in the maxillary sinus.

    29. Child 12 years old with swelling in the mandibular premolars area, first premolar clinically missing, in X ray examination we found Radiolucent is cover the percoronal part of the 3rd molar is:
    1. Dentigerous cyst. ***

    30. Young pt came without any complain. During routine X ray appear between the two lower molar lesion diameter about 2mm & extend laterally with irregular Shape. What’s the type of cyst
    a) dentigerous cyst
    b) apical cyst
    c) radicular cyst

    The Dentigerous (Follicular) Cyst, the most common of the developmental of odontogenic cysts, develops by the accumulation of fluid within the follicular space of an unerupted tooth after its crown has fully formed.

    The epithelial covering of the cyst is a thin regular layer made of few cell layers; it is defined as a pluristratified non keratinized epithelium.
    The metaplasia of the mucous membrane occurs frequently and increases as patient gets older. The cyst epithelium is covered by a capsule made of fibrous connective tissue that is usually relatively uninflamed except close to the junctional epithelium where a chronic inflammatory cell infiltrate may occur. Inside the cyst It can be found a protein fluid.

    -10-15% of maxillary odontogenic cysts
    -Wide range of age, especially occurs among adolescents and over 50s
    -No difference between males and females
    -No difference between maxilla and mandible
    -Dentigerous cyst may occur more often in unerupted teeth
    – The teeth most commonly affected are third molars and maxillary cuspids. No tooth is immune, but decidious teeth are scarcely ever affected.
    Small cysts are without symptoms but large ones expand the affected jaw and may cause pain and less often paresthesia .
    Based on rx evidence Dentigerous cysts appears as a well-circumscribed,usually unilocular pericoronal radiolucency; they often are in contact with the crown of an included tooth which can be dislocated by the growth of the cyst itself.

    31. Most commonly dentigerous cysts are associated with:
    a. Unerupted permanent maxillary canines
    b. Unerupted mandibular third molars. ***

    Cortical integrity, periosteal reaction and soft tissue
    Slow-growing lesions often cause expansion with cortical bowing, while cortical destruction denotes aggressive inflammatory or neoplastic lesions. Presence of periosteal reaction and soft tissue is also suggestive of an inflammatory or malignant aetiology. Some types of periosteal reactions are quite specific, like the sunburst type in osteosarcoma.

    Periapical and occlusal radiography and orthopantomography revealed diffuse bone destruction on the left side of the mandible due to the presence of a lesion of variable appearance, presenting dense radiopaque, mixed and completely radiolucent areas. The lesion was extensive and poorly delimited, with the periosteum showing the classical “sunray” reaction on occlusal and periapical radiographs

    Perineural spread of malignant lesion in the parotid gland:
    – Worthin tumor
    – Ductal papilloma
    – Pleomorphic adenoma
    – Adenoid cystic carcinoma*****
    الجواب الصحيح هو الجواب الرابع متاكد من كتاب oral pathology and oral medicen page 267
    urrent research suggests that tumors play a more active role in perineural invasion than previously thought. NCAM is an immunoglobulin that has several functions (including adhesion, proliferation, and migration of neural cells) and is thought to play a role in perineural invasion. Several studies have shown that NCAM is expressed in a large percentage of patients with adenoid cystic carcinoma, although its role in perineural invasion associated with squamous cell carcinoma (SCCA) is not as well defined. Other studies have shown that a wide variety of neurotrophic growth factors and matrix metalloproteinases are also expressed in cancers that exhibit perineural spread.

    Perineural spread is a well-recognized phenomenon in head and neck cancers. SCCAs are the most frequent neoplasms to exhibit this behavior, followed by adenoid cystic carcinoma (ACC), lymphoma, and rhabdomyosarcoma. Because of their extensive and intricate network of nerve fibers within the head and neck, the trigeminal and facial nerves are the nerves most commonly affected. In addition, these nerves have various interconnections between them that serve as a mechanism for widespread dissemination.

    Oral Pathology – 4th Ed. (2005) J. V. Soames Professor of Oral Pathology University of Newcastle upon Tyne UK
    J. C. Southam Emeritus Professor of Oral Medicine and Oral Pathology University of Edinburgh UK
    In dentistry, the epithelial cell rests of Malassez or epithelial rests of Malassez (frequently abbreviated as ERM) are part of the periodontal ligament cells around a tooth. They are discrete clusters of residual cells from Hertwig’s epithelial root sheath (HERS) that didn’t completely disappear. It is considered that these cell rests proliferate to form epithelial lining of various odontogenic cysts such as radicular cyst under the influence of various stimuli. They are named after Louis-Charles Malassez (1842–1909) who described them. Some rests become calcified in the periodontal ligament (cementicles)

    Dental secrets – page 66
    19. What is the difference between a lateral radicular cyst and a lateral periodontal cyst?
    A lateral radicular cyst is an inflammatory cyst in which the epithelium is derived from rests of Malassez (like a periapical or apical radicular cyst). It is in a lateral rather than an apical location because the inflammatory stimulus is emanating from a lateral canal. The associated tooth is always nonvital. The lateral periondontal cyst is a developmental cyst in which the epithelium probably is derived from rests of dental lamina. It is usually located between the
    mandibular premolars, which are vital.

    Clinical appearance Most often seen as a painless ulcer, although may present as a swelling, an area of leukoplakia, erythroleukoplakia or erythroplakia (A reddened patch), or as malignant change of long-standing benign tumours or rarely in cyst linings. Pain is usually a late feature when the lesion becomes superinfected or during eating of spicy foods. Referred otalgia is a common manifestation of pain from oral cancer. The ulcer is described as firm with raised edges, with an indurated, inflamed, granular base and is fixed to surrounding tissues.

If the collarbones are completely missing or reduced to small vestigesاثار, this allows hypermobility of the shoulders including ability to touch the shoulders together in front of the chest.A soft spot or larger soft area in the top of the head where the fontanelle failed to close.

    Bones and joints are underdeveloped. People are shorter and their frames are smaller than their siblings who do not have the condition.
    The permanent teeth include supernumerary teeth. Unless these supernumeraries are reabsorbed before adolescence, they will crowd the adult teeth in what already may be an underdeveloped jaw. In that case, the supernumeraries will probably need to be removed to provide space for the adult teeth.
    Permanent teeth not erupting

    – Eagle syndrome.
    – Gorlin – Goltz syndrome.***
    – Pierre Robin syndrome.
    – Non of the above.
    Gorlin-Goltz syndrome, also known as nevoid basal cell carcicoma syndrome, is caused due to a genetic alteration produced by a mutation in the “Patched” tumor suppressor gene, and it is inherited in a dominant autosomal way, though sporadic cases have been found. This syndrome shows a high penetrance and variable expressiveness. It is a multisystemic process that is characterized by the presence of multiple pigmented basocellular carcinomas, keratocysts in the jaws, palmar and/or plantar pits and calcification of the falx cerebri. Together with these major features, a great number of processes considered as minor features have also been described. The latter include numerous skeletal, dermatology related and neurological anomalies, among others. In some occasions, the presence of very aggressive basocellular carcinomas has been described as well as other malignant neoplasia. Due to the importance of oral maxillofacial manifestations of this syndrome, it is fundamental to know its characteristics in order to make a diagnosis, to provide an early preventive treatment and to establish right genetic advice. We report a rare association of Gorlin-Goltz syndrome with situs oppositus.

    Dentinogenesis imperfecta, classified into three subtypes, occurs in about 1 in 8,000 newborns in the U.S. The teeth can be bluish or brownish with a somewhat translucent appearance. On x-ray, the teeth of patients with dentinogenesis imperfecta III (DGI-III) appear as ‘shell teeth,’ with a layer of enamel, a thin layer of dentin, and very large pulp chambers. Because of the unstable dentin, the enamel can shear off and expose the dentin, which could then wear down to the pulp. Most of those severely affected with DGI-III are candidates for dentures or implants by age 30 despite dental intervention

    A clot may fail to form because of a quantitative or functional platelet
    deficiency. The former is most readily assessed by obtaining a platelet count. The
    normal platelet count is 200,000—500,000 cells/mm3 Prolonged bleeding may
    occur if platelets fall below 100,000 cells/ mm3. Treatment of severe
    thrombocytopenia may require platelet transfusion. Qualitative platelet dysfunction
    most often results from aspirin ingestion and is most commonly measured by
    determining the bleeding time. Prolonged bleeding time requires consultation with

    a. True.
    b. False. ***

    Although most HSV-1 infections are subclinical, a small percentage of patients develop primary herpetic gingivostomatitis.1 Typical symptoms include abrupt onset of fever, anorexia, irritability and intense mouth pain. Patients develop oral lesions of the attached and movable mucosal surfaces in which vesicles develop and quickly break down, coalescing to form large painful ulcerations. The gingivae become erythematous and tender.

    Anatomy of the Human Body – Henry Gray – page 27
    – The mandibular arch lies between the first branchial groove and the stomodeum; from it are developed the lower lip, the mandible, the muscles of mastication, and the anterior part of the tongue.
    – The ventral ends of the second and third arches unite with those of the opposite side, and form a transverse band, from which the body of the hyoid bone and the posterior part of the tongue are developed.
    Anatomy of the Human Body – Henry Gray – page 693
    During the third week there appears, immediately behind the ventral ends of the two halves of the mandibular arch, a rounded swelling named the tuberculum impar, which was described by His as undergoing enlargement to form the buccal part of the tongue. More recent researches, however, show that this part of the tongue is mainly, if not entirely, developed from a pair of lateral swellings which rise from the inner surface of the mandibular arch and meet in the middle line.

    Master Cone Will Not Fit to Length:
    • Dentine chips packed into the apical extent of the root canal preparation will lead to a decrease in working length, and consequently the master cone will appear to be short. This can be avoided by using copious amounts of irrigant during preparation.
    • A ledge in the root canal wall can prevent correct placement of the cone. If the cone hits an obstruction during placement then the end may appear crinkled. It may be possible to remove or smooth a ledge by refining the preparation with a greater taper instrument.
    • If the canal is insufficiently tapered, the master cone may not fit correctly because it is binding against the canal walls coronally or in the mid-third. The completed root canal preparation should follow a gradual taper along its entire length. Further preparation may be required with Gates-Glidden burs, orifice shapers or a greater taper instrument.

    This situation is often referred to as a “weeping canal” and is annoying in that the apical part of the canal cannot be dried properly. The right therapy is a discontinuation of the use of the tissue-irritating antiseptics followed by 2–3 weeks of calcium hydroxide in the root canal. The chemically-induced exudation will then have stopped and the root canal can be dried and obturated.

    Clinical Endodontics textbook TRONSTAD – page 150
    Irrigation with copious amounts of 5 % sodium hypochlorite may have some effect, but the treatment of choice is to pack the canal and the resorption lacuna with calcium hydroxide paste. By the next visit, the calcium hydroxide will have necrotized any remaining tissue in the lacuna, and the necrotic remnants are readily removed by irrigation with sodium hypochlorite.

    method used to remove an
    existing root filling will depend on the type of the

    Gutta-percha is relatively simple to remove
    (Fig. I). A gap may be made between a poorly
    condensed filling and the root canal wall with an
    explorer. A Hedstroem file (size 20 or above) is
    then screwed into the space. A second and, if
    possible, a third files are inserted to engage the
    mass of the gutta-percha.. ….
    Metal points
    The method of removing silver or titanium
    points is dictated by their position within the root
    canal. Single point root fillings are easy to remove
    if they extend into the pulp chamber with the
    coronal end long enough to be grasped by either
    the Steglitz forceps, narrow-beaked artery forceps,
    or a pair of pliers with fine beaks. If the metal
    point lies in the root canal below the pulp chamber
    but in the straight part of the canal, the Masserann
    fragment remover kit may be used

    The noncommunicating fracture occurs in the apical or middle third of the root. Perform a vitality test, check for color change in the crown, and record the degree of mobility of each traumatized tooth. If the pulp is vital, then immobilize the tooth by splinting it to the adjacent teeth……………….
    …….If the fracture of any part of the root is coronal to the periodontal attachment,The fractured part should be removed during the emergency visit, and endodontic treatment should be done in one visit. Once the emergency has been taken care of, plans must be made for restoring the tooth.

    a. Require minimum interocclusal distance. ***
    b. Have a great range of jaw movement.
    c. Require careful occlusion, usually cuspless teeth are indicated. عديمة الحدبات

    Complete Denture 17th Ed – page 16
    RESIDUAL RIDGE RELATIONSHIP: Class II or retrognathic is usually difficult as the patient looks toothy, often holds the mandible forward to improve appearance with subsequent TMJ problems, usually have a great range of jaw movements in function, require careful occlusion, and usually needs a large interocclusal distance. Class Ill or prognathic is usually easier if not extreme. The patient usually functions on a hinge (little or no protrusive component) and requires a minimum of interocclusal distance. In any case, do not set the teeth for a retrognathic or prognathic patient in a normal relationship, unless there is only a moderate deviation from Class I.

    Gagging (nausea): loose denture – thick distal termination of upper denture – lingual placement of upper denture – occlusal plane low.
    Complete Denture 17th Ed – page 128
    3. Gagging:
    a. Psychogenic -starts in mind, very difficult to treat
    b. Stomatogenic -starts in body (usually dentures), treatable
    c. Dental causes:
    1. Lack of retention
    2. Poor occlusion
    3. Insufficient or excessive palatal seal. أي سد خلفي ناقص أو مفرط بالزيادة
    4. Crowded tongue due to a thick palate or poor tooth placement
    5. Excessive salivation
    6. Excessive vertical dimension (often seen in new dentures)
    Denture over-extension onto the soft palate may stimulate a gag reflex directly by continuous contact or indirectly by intermittent contact brought about by the activity of the soft palate or posterior third of the tongue.
    An under-extended denture (or an unstable denture from occlusal interferences) will lack a posterior seal, will dislodge intermittently, irritate the posterior third of the tongue and thus cause nausea.
    A palpable and thickened posterior border will also irritate the tongue. Interference with tongue space, as in an excessively large vertical dimension which causes compensatory protrusion of the tongue, or in a narrow arch which forces the tongue to occupy an unnatural position, may also manifest as nausea.
    الخيار الثالث لا يسبب منعكس إقياء (لأنه امتداد زائد قليلاً للخلف)

    Regardless of the method used in creating a harmonious
    functional occlusion, an evaluation of the
    existing relationships of the opposing natural teeth
    must be made and is accomplished with a diagnostic
    mounting. This evaluation is in addition to, and in
    conjunction with, other diagnostic procedures that
    contribute to an adequate diagnosis and treatment
    Diagnostic casts provide an opportunity to evaluate
    the relationship of remaining oral structures
    when correctly mounted on a semiadjustable articulator
    by use of a face-bow transfer and interocclusal
    records. Diagnostic casts are mounted in centric
    relation (most retruded relation of the mandible to
    the maxillae) so that deflective occlusal contacts can
    be correlated with those observed in the mouth.
    Deflective contacts of opposing teeth are usually
    destructive to the supporting structures involved and
    should be eliminated.

    Oxford Handbook of Clinical Dentistry – 4th Ed. (2005) – page 194
    Resting face height is assessed using:
    • A Willis gauge, to measure the distance between the base of nose and the underside of the chin. Is only accurate to ±1 mm.
    • Spring dividers, to measure the distance between a dot placed on both the chin and the tip of the patient’s nose. This method is less popular with patients and is C/I for bearded gentlemen (or ladies!).

    للمعلومية الخيار كان pt has extensive sever gag reflex
    الله اعلم بس تركيزهم على مدى سوء ال gag خلاني احس انو لو المشكلة extensive sever gag مش ممكن تروح في ايام لحالها من غير تدخل من الدكتور و ترجع فجأة لحالها بعد خمس سنين. و الله اعلم هذا رأي شخصي مش اكثر

    17) patient with 5 years old denture has a severe gag reflex , upon history he says he had the same symptoms in the first few days of the denture delievery and it went all alone:
    patient has severe gag reflex.
    patient has underlying systemic condition. ***
    denture is overextended.

    Nausea (gag reflex) is the urge to vomit. It can be brought by many causes including, systemic illnesses, such as influenza, medications, pain, and inner ear disease.
    لو كان الخيار الأول لما توقف منعكس الإقياء أبداً، ولو كان الخيار الثالث لبقي المنعكس حتى يتم إزالة الامتداد الزائد للجهاز، الخيار الثاني منطقي لأن بعض الأمراض العامة تسبب منعكس الإقياء.

    Patient have a complete denture come to your clinic he complain of gagging he wear the denture for 5 years he feel the gagging in the first few days and it disappear what is the cause:
    1. Extend of the upper denture.
    2. The patient has sensitivity to gagging.

    31. The posterior seal in the upper complete denture serves the following functions:
    a. It reduces Pt discomfort when contact occurs between the dorsum of the tongue and the posterior end of the denture base. ظهر اللسان
    b. Retention of the maxillary denture.
    c. It compensate for dimensional changes which occur in the acrylic denture base during processing.
    d. A& b are correct. ***

    أول جوابين لأن حسب:
    المرجع: التعويضات المتحركة الكاملة – جامعة دمشق 2006
    المهمة الرئيسية للختم الحنكي الخلفي هي تثبيت جهاز الفك العلوي، والسد الحنكي الخلفي الذي تم تشخيصه وتصميمه بشكل صحيح في الجهاز السني سوف يحد من إدراك المريض بهذه المنطقة مع اختفاء لاحق لمنعكس الإقياء، ويحافظ على التماس المستمر بين قاعدة الجهاز السني والحنك الرخو أثناء الحركات الوظيفية العادية، مما سيؤدي إلى عدم اندخال الطعام تحت الناحية الخلفية من الجهاز السني، إضافة إلى تأمين ختم جيد للحواف يؤدي إلى تشكيل صمامة هوائية تمنع تسرب الهواء إلى ما تحت قاعدة الجهاز، وبالتالي زيادة الثبات وكذلك التخفيف من حدة عدم راحة المريض عند ظهور التلامس بين ظهر اللسان ونهاية القسم الخلفي من قاعدة الجهاز السني لأن الحد الخلفي من الجهاز السني سوف يمس الأنسجة الحنكية ويصبح غير محسوس من قبل اللسان مما يؤدي إلى عدم انزعاج المريض وغياب منعكس الإقياء لديه.

    19. All relate to retention of maxillary complete denture except:
    a. Tongue movement.
    b. Type of saliva. الأصح
    جهاز علوي؟؟؟؟؟؟؟؟؟

    السؤال يخص جهاز كامل علوي، في جميع المراجع والصفحات التي وجدتها، يوجد تركيز أكثر على نوعية اللعاب، وبخصوص اللسان فالمذكور هو توضعه بالناحية الأمامية وإمكانية إثارة منعكس الإقياء إذا تحرك الجهاز أولاً ثم لامس اللسان.

    دور اللعاب دور مؤكد من خلال إفرازه من غدد قبة الحنك اللعابية في الرابط التالي:

    من حيث النوعية:
    § لعاب رقيق (غير لزج): ينقص ثبات واستقرار الجهاز / لعاب قليل: الجهاز سيسبب تخريش اللثة والتهابها.
    § لعاب كثيف ولزج (مخاطي): يُشكِّل طبقة يلتصق بالجهاز ويزعج المريض.

    وحسب كتاب التعويضات المتحركة الكاملة:
    “وأما الغدد الحنكية فكثيرة جداً، وتتجمع خاصة عند اتصال قبة الحنك الصلبة بالشراع الرخو، وهي ذات تأثير يعين على ثبات الجهاز وذلك لأنّها تفرز طبقة لعابية تحول دون احتكاك الجهاز بالغشاء المخاطي، وهي أشبه بوسادة مائية توزع الضغط توزيعاً متساوياً في المنطقة الخلفية ( السد الخلفي )، وتؤمن مرونة كافية للنسج التي تقع بتماس الجهاز المتحرك، فتساهم هذه المفرزات اللزجة بثبات الجهاز .”

    حسب كل هذا التحليل الخيار الأول هو الصحيح أي أن تأثير حركة اللسان أقل أهمية من تأثير اللعاب في ثبات الجهاز العلوي.

    Digital imaging
    This technique has been used extensively in general radiology, where it has great advantages over conventional methods in that there is a marked dose reduction and less concentrated contrast media may be used. The normal X-ray source is used but the receptor is a charged coupled device linked to a computer or a photo-stimulable phosphor plate which is scanned by a laser. The image is practically instantaneous and

    chlorohexidine has several disadvantages. One of the most important disadvantages is that if a patient rinses his mouth with chlorohexidine compositions regularly, his teeth and tongue obtain a brownish colour. This is off course a major disadvantage. Another disadvantage of chlorohexidine is that it has no significant anti-bacterial effect on gram positive bacteria at relatively low concentrations. This means that gram positive bacteria will not be effected by the rinse composition and may thus still cause periodontitis or produce the volatile sulphur compounds that cause the malodour.

    Atropine: It is classified as an anticholinergic drug
    Injections of atropine are used in the treatment of bradycardia (an extremely low heart rate), asystole and pulseless electrical activity (PEA) in cardiac arrest. This works because the main action of the vagus nerve of the parasympathetic system on the heart is to decrease heart rate. Atropine blocks this action and, therefore, may speed up the heart rate.
    Atropine’s actions on the parasympathetic nervous system inhibits salivary, sweat, and mucus glands.
    Atropine induces mydriasis by blocking contraction of the circular pupillary sphincter muscle, which is normally stimulated by acetylcholine release
    Dental Decks – page 2012 – 2192
    Scopolamine, atropine and benztropine are anticolinergic drugs. They decrease the flow of And salive.Cholinesterase inhibition is associated with a variety of acute symptoms such as nausea, vomiting, blurred vision, stomach cramps, and rapid heart rate.

    تصحيح أرجو الانتباه له:
    – Cholinergic يزيد اللعاب ويبطئ النبض ويزيد الإفراز المعدي
    – anticholinergic تنقص اللعاب وتوسع الحدقة وتزيد النبض وتنقص الإفراز المعدي

    • Up to 500 mg of hydrocortisone IV.
    • Up to 20 mg of chlorpheniramine slowly IV (if available).
    • O2 by mask.
    السلام عليكم يعطيك العافية دكتور ايهم كلامك صح انا وجدت مرجع بيقول انه العلاج الاساسي في هيك حالة هو الادرينالين الالفي نصف مل عضليا او تحت الجلد
    و ممكن اعطاء clorphinairamine ببطء 20 ملغ وريديا مع الادرينالين في الحالات الشديدة او كبديل اذا لم يتوفر الادرينالين وهو طبعا انتي هيستامين
    و للفائدة اذكر ان علاج الهجمة الحادة للربو Athma هو بالادرينالين الالفي ايضا نصف مل عضليا
    او بديل عنه للربو هو الامينو فيلين وريديا ببطئ شديد
    وشكرا الك دكتور ايهم
