    In an adult patient with chronic adult periodontitis the most successful approach to treatment is:?

    • Surgery

    • Extreme initial treatment followed by reviews every year

    • Initial periodontal therapy followed by maintenance therapy alone

    Correct Answer
    A. Initial periodontal therapy followed by maintenance therapy alone
    Explanation
    The most successful approach to treatment for an adult patient with chronic adult periodontitis is initial periodontal therapy followed by maintenance therapy alone. This approach involves an initial deep cleaning and scaling of the teeth and gums to remove plaque and tartar buildup. After this initial treatment, regular maintenance therapy, including professional cleanings and proper oral hygiene practices, is crucial to prevent further progression of the disease and maintain the health of the gums and teeth. Surgery may be necessary in some cases, but it is not the most successful approach for all patients.

    In an adult patient with chronic adult periodontitis the most successful approach to treatment is?

    • Surgery

    • Extreme initial treatment followed by reviews every year

    • Initial periodontal therapy followed by maintenance therapy alone

    Correct Answer
    A. Initial periodontal therapy followed by maintenance therapy alone
    Explanation
    The most successful approach to treatment for an adult patient with chronic adult periodontitis is initial periodontal therapy followed by maintenance therapy alone. This approach involves a thorough initial treatment to remove plaque and calculus, followed by regular maintenance visits to prevent the recurrence of periodontal disease. This approach has been shown to effectively control the progression of periodontitis and maintain periodontal health in the long term. Surgery and extreme initial treatment followed by yearly reviews may be considered in more severe cases, but the initial periodontal therapy followed by maintenance therapy alone is the most successful approach in general.

    All the following are phases of periodontal treatment plan except: ?

    • Surgical phase

    • Maintenance phase

    • Non-surgical phase

    • Refractory phase

    Correct Answer
    A. Refractory phase
    Explanation
    The refractory phase is not a phase of periodontal treatment plan. The surgical phase involves surgical procedures to treat periodontal disease, while the non-surgical phase includes non-invasive treatments such as scaling and root planing. The maintenance phase focuses on regular check-ups and cleanings to prevent further progression of the disease. However, the refractory phase is not a recognized phase in periodontal treatment and is therefore not included in the options.

    During an acute gingival inflammation response, which of the following cell types can destroy virulent bacteria by phagocytosis and T-cell mediation?

    • Plasma cells

    • Mast cells and Polymorphonuclear

    • Limphocytes

    • Macraphage

    Correct Answer
    A. Macraphage
    Explanation
    Macrophages are a type of white blood cell that play a crucial role in the immune response. During acute gingival inflammation, macrophages can destroy virulent bacteria through phagocytosis, which is the process of engulfing and digesting pathogens. Additionally, macrophages can also mediate the immune response through T-cell activation, further aiding in the destruction of bacteria. Therefore, macrophages are an important cell type involved in the defense against virulent bacteria during acute gingival inflammation.

    Periodontal attachment loss detect clinically: ?

    • When there is recession only.

    • When there is radiographic alveolar bone loss.

    • When there is true pocket only.

    • When there is recession and/or true pocket.

    Correct Answer
    A. When there is recession and/or true pocket.
    Explanation
    The correct answer is "When there is recession and/or true pocket." Periodontal attachment loss can be detected clinically when there is either recession or a true pocket present. Recession refers to the exposure of the root surface due to the loss of gum tissue, while a true pocket is a deepening of the gum pocket around the tooth. Both of these conditions indicate a loss of attachment between the tooth and the surrounding tissues, which can be assessed during a clinical examination.

    Subgingival curettage should provide favourable results in?

    • Fibrotic gingivitis

    • Infrabony pockets

    • None of the above

    • Oedematous gingivitis

    Correct Answer
    A. Oedematous gingivitis
    Explanation
    Subgingival curettage involves removing the infected tissue and debris from the area below the gum line. It is an effective treatment for oedematous gingivitis, which is characterized by swollen and inflamed gums due to poor oral hygiene. By removing the infected tissue, subgingival curettage can help reduce inflammation, promote healing, and improve the overall health of the gums. However, it may not be as effective in treating fibrotic gingivitis or infrabony pockets, which may require additional treatments such as surgery or periodontal therapy.

    Which of the incisions is not followed in periodontal flap surgeries?

    • Crevicular

    • Interdental

    • Internal bevel

    • External bevel

    Correct Answer
    A. External bevel
    Explanation
    Periodontal flap surgeries involve making incisions in the gum tissue to gain access to the underlying structures. Crevicular, interdental, and internal bevel incisions are commonly used in these surgeries. However, the external bevel incision is not followed in periodontal flap surgeries. This type of incision involves making a beveled cut on the external surface of the gum tissue, which is not typically done in periodontal flap surgeries.

    The primary aetiologic factor in the development of furcation defect is?

    • Calculus

    • Cemental caries

    • Root infection

    • Plaque

    Correct Answer
    A. Plaque
    Explanation
    Plaque is the correct answer because it is the main cause of furcation defects. Plaque is a sticky film that forms on teeth and contains bacteria. If plaque is not removed through proper oral hygiene practices, it can lead to gum inflammation and infection. Over time, this can cause damage to the supporting structures of the teeth, including the furcation area where the roots of multi-rooted teeth meet. This can result in furcation defects, which can lead to further complications such as tooth mobility and tooth loss.

    What are advantages of a positive knot when compared to a negative knot?

    • No memory

    • Hold the not better

    • Hold the not for longer

    • Better wound closer

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    A positive knot has several advantages over a negative knot. Firstly, it has no memory, meaning it does not retain any previous shape or form. This makes it easier to tie and untie without any complications. Secondly, a positive knot holds the knot better, ensuring that it stays in place and does not come undone easily. Additionally, it can hold the knot for a longer period of time, providing more durability and reliability. Lastly, a positive knot creates a better wound closer, ensuring that the wound is properly sealed and reducing the risk of infection. Therefore, all of the above advantages make a positive knot preferable over a negative knot.

    What is the crown-to-root ratio in a healthy dentition?

    • As a general rule, the crown-to-root ratio in a healthy dentition is 1:1 (for each tooth).

    • As a general rule, the crown-to-root ratio in a healthy dentition is 2:1 (for each tooth).

    • As a general rule, the crown-to-root ratio in a healthy dentition is 1:3 (for each tooth).

    • As a general rule, the crown-to-root ratio in a healthy dentition is 1:2 (for each tooth).

    Correct Answer
    A. As a general rule, the crown-to-root ratio in a healthy dentition is 1:2 (for each tooth).
    Explanation
    The crown-to-root ratio in a healthy dentition refers to the proportion between the visible part of the tooth (the crown) and the part that is embedded in the jawbone (the root). A 1:2 crown-to-root ratio means that the length of the root is twice the length of the crown. This ratio is considered ideal for maintaining the stability and support of the tooth within the jawbone, ensuring proper function and longevity of the tooth.

    The Lingual nerve ?

    • Can never be hurt during dental procedure

    • Is important for the mobility of the tongue

    • Is a branch of the mental nerve

    • Is very sturdy and recovers quickly from injury

    • Can easily be injured when cutting too lingually in the molar area

    Correct Answer
    A. Can easily be injured when cutting too lingually in the molar area
    Explanation
    The correct answer is "Can easily be injured when cutting too lingually in the molar area." The lingual nerve is a branch of the mandibular division of the trigeminal nerve and provides sensory innervation to the tongue. It runs along the lingual aspect of the mandible, close to the lingual surface of the molars. Therefore, when performing dental procedures in the molar area, there is a risk of injuring the lingual nerve if the cut is made too lingually.

    Acellular dermal grafts work best when they are completely submerged beneath a mucoperiosteal flap during healing. ?

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Acellular dermal grafts are most effective when they are fully covered by a mucoperiosteal flap during the healing process. This ensures that the graft remains protected and undisturbed, allowing for proper integration and optimal healing. By being submerged beneath the flap, the graft is shielded from external forces and can successfully regenerate and integrate with the surrounding tissues. Therefore, the statement "Acellular dermal grafts work best when they are completely submerged beneath a mucoperiosteal flap during healing" is true.

    Which of the following is NOT a function of a provisional restoration ?

    • It communicates the desired gingival margin to the surgeon

    • It allows the patient to evaluate esthetics

    • It allows the patient to evaluate phonetics

    • It may acts as a permanent restoration

    Correct Answer
    A. It may acts as a permanent restoration
    Explanation
    A provisional restoration is a temporary restoration that is placed in the mouth while a permanent restoration is being fabricated. It is used to communicate the desired gingival margin to the surgeon, allowing them to shape the gum tissue accordingly. It also allows the patient to evaluate the esthetics of the final restoration and assess how it affects their speech (phonetics). However, a provisional restoration is not intended to act as a permanent restoration as it is not as durable or long-lasting.

    Autografts refer to ?

    • The transplantation of tissue from one individual to a different individual

    • The transplantation of tissue from an animal to an individual

    • The transplantation of tissue from one individual to the same individual

    Correct Answer
    A. The transplantation of tissue from one individual to the same individual
    Explanation
    Autografts refer to the transplantation of tissue from one individual to the same individual. Autografts are considered the ideal type of graft because they have a lower risk of rejection compared to grafts from another individual or an animal. This is because autografts use the individual's own tissue, which is genetically identical and therefore less likely to be recognized as foreign by the immune system. Autografts are commonly used in procedures such as skin grafts, bone grafts, and organ transplants.

    For human patients, all of these could be sources of xenografts except?

    • Pigs

    • Cows

    • Horses

    • Humans

    Correct Answer
    A. Humans
    Explanation
    Xenografts refer to the transplantation of living cells, tissues, or organs from one species to another. In the context of human patients, xenografts can be obtained from animals such as pigs, cows, and horses. However, humans cannot be a source of xenografts as it would involve transplanting tissues or organs from one human to another, which is known as an allograft. Therefore, humans are not a viable source of xenografts for human patients.

    • Premaxilla.

    • MaxillaryTubersity.

    • External oblique ridge of the mandible.

    • Maxillary Tubersity and External oblique ridge of the mandible.

    Correct Answer
    A. Maxillary Tubersity and External oblique ridge of the mandible.
    Explanation
    The maxillary tuberosity and external oblique ridge of the mandible are both anatomical areas that can be used as a source for bone graft harvest for periodontal regenerative surgical procedures. These areas provide sufficient bone volume and density to support the regeneration of periodontal tissues.

    Adult patient present clinically with irregular thickness of buccal gingiva, a round diamond bur used to correct and establish a physiological gingival contour. The type of this procedure is/are:?

    • Gingivectomy.

    • Combined gingivoplasty & gingivectomy.

    • None of the above.

    • Gingivoplasty.

    Correct Answer
    A. Gingivoplasty.
    Explanation
    The correct answer is Gingivoplasty. Gingivoplasty is a surgical procedure performed to reshape and contour the gingiva. In this case, the irregular thickness of the buccal gingiva is being corrected using a round diamond bur, which is a common tool used in gingivoplasty procedures. Gingivectomy, on the other hand, involves the removal of gum tissue, and combined gingivoplasty and gingivectomy refers to a combination of both procedures. None of these options accurately describe the procedure being performed in this scenario.

    Curettage comes under?

    • Phase-II

    • Phase-Ill

    • Phase-IV

    • Phase-1

    Correct Answer
    A. Phase-1
    Explanation
    Curettage is a surgical procedure that involves scraping or scooping out tissue from the lining of a body cavity or a wound. It is commonly used in gynecology, dermatology, and dentistry. In the context of the question, the term "Phase-1" refers to the initial phase or stage of a medical treatment or clinical trial. Therefore, the correct answer is Phase-1, as curettage is typically performed as a part of the initial treatment or evaluation process.

    A patient returned on week after scaling and prophylaxis. Hard black deposits of calculus are noted in gingival margin. This indicates?

    • Patient is a heavy tea drinker

    • Poor maintenance and formation of new calculus

    • Blood clots which are not removed from tooth surface

    • Shrinkage of tissue due to reduction in inflammation after scaling

    Correct Answer
    A. Shrinkage of tissue due to reduction in inflammation after scaling
    Explanation
    The presence of hard black deposits of calculus in the gingival margin one week after scaling and prophylaxis suggests that there has been a reduction in inflammation after the procedure. This reduction in inflammation can cause the gingival tissue to shrink, making the calculus more visible. This explanation is supported by the fact that the other options (heavy tea drinking, poor maintenance and formation of new calculus, and blood clots not being removed) do not directly explain the presence of hard black deposits of calculus in the gingival margin.

    The only valid method to assess periodontal regeneration is?

    • Radiographic analysis

    • Clinical attachment level

    • Reentry operation

    • Histologic analysis

    Correct Answer
    A. Histologic analysis
    Explanation
    Histologic analysis is the only valid method to assess periodontal regeneration because it involves the microscopic examination of tissue samples. This allows for a detailed evaluation of the quality and quantity of regenerated periodontal tissues, including the formation of new bone, cementum, and periodontal ligament. Radiographic analysis can provide information about bone levels, but it cannot differentiate between newly formed and existing bone. Clinical attachment level measures the distance between the base of the pocket and the cemento-enamel junction, but it does not provide information about the quality of regenerated tissues. Reentry operation involves surgical access to evaluate the healing process, but it is invasive and may disrupt the newly formed tissues. Therefore, histologic analysis is the most accurate and reliable method to assess periodontal regeneration.

    What is the most common indication for Coronally Positioned Flap?

    • Ridge augmentation

    • Primary wound closer

    • Secondary would closer

    • Non of the above

    • Root coverage

    Correct Answer
    A. Root coverage
    Explanation
    The most common indication for a Coronally Positioned Flap is root coverage. This surgical technique is commonly used in periodontal therapy to treat gingival recession and expose more of the tooth's root surface. By repositioning the gum tissue, the flap helps to cover and protect the exposed root, improving aesthetics and reducing sensitivity.

    What kind of tissues should compose of Full Thickness Flap?

    • Epithelium, Connective Tissue

    • Epithelium only

    • Periosteum only

    • Connective Tissue, and Periosteum

    • Epithelium, Connective Tissue, and Periosteum

    Correct Answer
    A. Epithelium, Connective Tissue, and Periosteum
    Explanation
    A full thickness flap should consist of epithelium, connective tissue, and periosteum. This is because a full thickness flap is a surgical technique used in procedures such as skin grafts or flap reconstructions, where a piece of tissue is completely detached from its blood supply and moved to another location. In order for the flap to survive and heal properly, it requires all layers of tissue including the outermost layer of epithelium, the underlying connective tissue, and the periosteum which is the specialized connective tissue covering the bones.

    What is (are) the most important anatomical structures to be respected during surgery?

    • Mental foramen

    • Greater palatine foramen and neuromuscular bundle

    • Incisive foramen

    • Lingual artery and nerve

    • All of the above

    Correct Answer
    A. All of the above
    Explanation
    During surgery, it is crucial to respect and be aware of the important anatomical structures to avoid any potential complications. The mental foramen is a vital structure located in the mandible, through which the mental nerve and vessels pass. The greater palatine foramen and neuromuscular bundle are significant structures in the hard palate, responsible for sensory innervation. The incisive foramen is an anatomical landmark in the maxilla, where the nasopalatine nerve passes through. Lastly, the lingual artery and nerve are essential structures in the tongue that need to be respected during surgery. Therefore, all of the above structures are crucial and should be considered during surgical procedures.

    Which bony defect is most likely to repair or fill naturally after treatment?

    • Two wall periodontal defects

    • One wall Periodontal defects

    • All above are repaired or filled naturally after treatment

    • Three-wall periodontal defects

    Correct Answer
    A. Three-wall periodontal defects
    Explanation
    Three-wall periodontal defects are most likely to repair or fill naturally after treatment. This is because three-wall defects have better blood supply and a more favorable environment for bone regeneration compared to two-wall or one-wall defects. The presence of three walls provides better stability and support for the regeneration process, allowing for natural healing and filling of the defect.
