Le Fort I fractures involve a horizontal fracture of the maxilla at the level of the nasal floor. The maxillary antra are located within the maxilla above the upper teeth, and this type of fracture commonly involves bleeding into these antra. Bleeding from the ear is usually temporal bone related, and CSF rhinorrhea is seen in Le Fort II or III fractures.

Conservative DentistryExplanation: In modified Class III cavity restorations, particularly those involving composite materials, retention is often achieved through acid etching. This process creates micro-retentive features on the enamel and dentin surfaces, allowing the bonding agent to penetrate and create a strong bond with the tooth structure. While retentive grooves, points, and pins can also be used, acid etching is a fundamental technique that enhances retention in adhesive dentistry.

Public Health DentistryStratified sampling is a probability sampling technique where the population is divided into homogeneous subgroups or "strata". A sample is then randomly selected from each stratum, which ensures that each subgroup is adequately represented in the final sample. This method helps to reduce sampling error and ensures more precise estimates of population characteristics compared to simple random sampling, especially when the population has natural variations or subgroups

Physiology
Pancreatic amylase is an enzyme that plays a key role in the digestion of carbohydrates. It is secreted into the duodenum in response to food and breaks down complex starches into simpler disaccharides like maltose and isomaltose. These disaccharides are then further hydrolyzed by other enzymes into glucose for absorption.
