The eruption of primary teeth usually begins around 4-8 months of age with the eruption of the lower incisors, and is complete at around 30-36 months of age when second primary molars erupt. However, the timing of tooth eruption varies by as much as six months.

Halitosis originates from the Latin word “halitus,” which means breath, and the Greek suffix osis refers to a condition or pathologic process. This prevalent disorder, also referred to as bad breath, used to explain the unpleasant breath emitted from the mouth of either oral or nonoral origin that seems unpleasant or offensive to others.

Grooves or pits and fissures on occlusal surfaces of primary and permanent posterior teeth trap food debris and promote the presence of bacteria due to their deep and morphological complexity thereby increasing the risk of developing cavities. Effectively penetrating and sealing these surfaces with a dental material like pit-and-fissure sealants providing a physical barrier that inhibits microorganisms and food particles accumulation can prevent lesions.
