As per Glickman’s classification, which furcation involvement is characterized by partial destruction of bone in one or more aspects of the furcation area?

Grades III and IV furcation involvement appear radiographically as a radiolucent area between the roots of a mandibular molar. This radiographic presentation can be challenging to see in the maxillary molars due to the three roots overlapping each other.

Which of the following is optimally achieved through treatment with root planning if the pocket depth is greater than 3.0 mm?

Plaque inhibition by chlorhexidine is dose-dependent. Nonetheless, lower concentrations are preferred due to fewer side effects and because higher concentrations don’t seem to be more effective in controlling plaque and gingivitis.

According to Seibert’s classification of alveolar ridge defects, which of the following describes a class III defect?

Apart from the traditional classification of furcation involvement by several authors, a subclassification that pertains to the amount of vertical bone loss has also been proposed. Which of the following describes a vertical bone loss of 4 to 6mm?

As per Glickman’s classification, which furcation involvement is classified as having only slight bone loss in the furcation area?

What is the minimum distance between a dental implant and the maxillary sinus?

After aggressive brushing, how much time is needed for plaque to form again?

Gain of clinical attachment level is greater with periodontal surgery than with root planing if the pocket depth is at least how many millimeters deep?

As per Horning and Cohen’s staging of oral necrotizing diseases, which stage is characterized by necrosis that perforates the skin of the cheek?

For pocket depths that are greater than 4.0 mm, the optimum gain of clinical attachment occurs through which treatment modality?

Apart from the traditional classification of furcation involvement by several authors, a subclassification that pertains to the amount of vertical bone loss has also been proposed. Which of the following describes a vertical bone loss of 7mm or more?

The period when plaque becomes easily visible and clinical signs of localized gingival inflammation can be observed is within:

What concentration of chlorhexidine is commonly used for mouthrinses?

As per Horning and Cohen’s staging of oral necrotizing diseases, which stage is characterized by necrosis affecting the entire papilla?

In the undisturbed areas of the dentition, after how many hours approximately does plaque start to become detectable?

The gingival crevicular fluid, or GCF, is a plasma-derived exudate found in the gingival sulcus. Its production increases as periodontal disease get worse.

Apart from the traditional classification of furcation involvement by several authors, a subclassification that pertains to the amount of vertical bone loss has also been proposed. Which of the following describes a vertical bone loss of 3mm or less?

The period when gingival inflammation starts to become generalized is within:

What is the mechanism of action of chlorhexidine?

Which of the following describes the threshold value of the probing depth, above which the outcome of therapy will result in attachment gain and below which the outcome of therapy will result in clinical attachment loss.

Which of the following most commonly used antiseptics have the greatest residual antimicrobial activity?

According to Seibert’s classification of alveolar ridge defects, which of the following describes a class II defect?

As per Glickman’s classification, which furcation involvement is characterized by through-and-through inter-radicular bone destruction that is not visible clinically?

Proxy brushes are used with which type of furcation?

What is the critical probing depth for root planing?

In electrosurgery, the voltage frequency range is:

Diameter of a perio probe is?

A patient complains of pain on biting and chewing, during examination there is a normal response to the cold and electric test, while there is severe pain on vertical and horizontal percussions, how should it be managed?

Which probe is shown in the picture?

1 to 3 mm pocket indicated
