Epidemiological surveys typically involve a cross-sectional or longitudinal approach (2) and often use dental indices (3) for data collection. Clinical trials generally involve control/experimental groups and smaller controlled samples.

Probing depth measurements provide historical data on periodontal attachment levels, reflecting the past and present condition of periodontal health. Tracking changes in probing depth is critical for assessing treatment success and disease progression

Resin teeth are more ductile than porcelain teeth, which means they can absorb and distribute forces better, making them less prone to chipping or fracturing on impact.

Endodontic treatment can be performed without removing orthodontic appliances. Access can be gained through the lingual surface or by carefully working around brackets. Removing arch wires interrupts orthodontic treatment unnecessarily.

The normal plasma concentration of glucose that does not lead to its excretion in the urine is approximately 100 mg/100 ml, below which glucose is typically reabsorbed completely.

The frozen section procedure is the examination of tissue to make a rapid microscopic diagnosis of a specimen while surgery is taking place. It is often used in oncological surgery to inform the surgeon if the surgical margin is clear of residual cancer, or if residual cancer is present at the surgical margin. 

The technical name for this procedure is cryosection. The report given by the pathologist is usually limited to a "benign" or "malignant diagnosis, and communicated to the surgeon operating via intercom. When operating on a previously confirmed malignancy, the main purpose of the pathologist is to inform the surgeon if the surgical margin is clear of residual cancer, or if residual cancer is present at the surgical margin

Bone graft procedures are most successful in treating narrow three-wall defects. These are defects that extend from the crest of the alveolar bone to the alveolar crest and involve only one surface of the tooth root. The success of a bone graft in such cases is due to the presence of three walls of intact bone that can provide stability and support for the graft material, allowing for predictable and effective regeneration of the missing bone tissue.
