OrthodonticsSOLUTION
Altered respiratory pattern, such as breathing through the mouth rather than the nose, could change the posture of the
head, jaw, and tongue. This in turn could alter the equilibrium of pressures on the jaws and teeth and affect both jaw growth and tooth position.
In order to breathe through the mouth, it is necessary to lower the mandible and tongue, and extend (tip back) the head.
If these postural changes were maintained, face height would increase, and posterior teeth would super-erupt;
unless there was unusual vertical growth of the ramus, the mandible would rotate down and back, opening the bite
anteriorly and increasing overjet; and increased pressure from the stretched cheeks might cause a narrower maxillary dental arch.

PathologyCells die by one of two mechanisms – necrosis or
apoptosis
• Two physiologically different processes
– Necrosis – death by injury
– Apoptosis – death by suicide
Appoptosis:
Disintegration of cells into membrane-bound particles that are then eliminated by phagocytosis or by shedding.

PeriodonticsExplanation:The success of a laterally positioned flap in periodontal surgery is influenced by several factors, including the presence of sufficient bone support at the donor site, the thickness of attached gingiva at the donor site, and the width of attached gingiva at the donor site. All these factors contribute to the healing and stability of the flap.

PeriodonticsExplanation:
For effective calculus removal, a tight instrument grasp combined with firm lateral working strokes is essential. This technique allows for better control and application of force, which is necessary to effectively dislodge calculus from the tooth surface.
