Case Reports in Dentistry
|February 24, 2016
Summary
Prolonged thumb sucking can cause anterior open bite (AOB). While a palatal expander helped initially, habit relapse led to AOB recurrence, highlighting the need for multidisciplinary care.
Area of Science:
- Dentistry
- Orthodontics
- Pediatric Dentistry
Background:
- Anterior open bite (AOB) and posterior crossbite are common malocclusions.
- Prolonged sucking habits are frequently associated with these dental issues.
Purpose of the Study:
- To illustrate the use of a Haas-type palatal expander in managing thumb sucking.
- To discuss the challenges and outcomes of treating AOB related to persistent sucking habits.
Main Methods:
- A clinical case study focusing on a patient with AOB and thumb sucking.
- Application of a Haas-type palatal expander to deter thumb sucking behavior.
Main Results:
- Initial improvement in AOB was observed upon habit discontinuation.
- Relapse of AOB occurred due to habit recurrence and lack of patient cooperation.
Conclusions:
- Palatal expanders can aid in habit cessation, but are insufficient alone for persistent habits.
- Successful treatment of AOB requires a multidisciplinary approach, patient consent, and cooperation for a favorable prognosis.

01:16Psychosexual Stages of Personality: Oral
3.7K
The oral stage is the initial phase of Sigmund Freud's theory of psychosexual development, occurring from birth to approximately 12 to 18 months. During this period, the infant's mouth serves as the primary source of pleasure, with actions such as sucking, chewing, biting, and drinking playing a crucial role in reducing tension. These activities are essential not only for nourishment but also for the infant's psychological and emotional satisfaction.

In preparing for oropharyngeal airway suctioning, a nurse must gather all necessary equipment, including a suction unit with tubing, a prepackaged suction kit, sterile gloves, water or saline for irrigation, a water-soluble lubricant, and additional personal protective equipment (such as a gown, mask, and goggles) to control infections.
After assembling the equipment, the nurse should practice hand hygiene and don appropriate PPE according to infection control guidelines to avoid the...

Nasopharyngeal suctioning is a procedure to remove secretions from the upper part of the respiratory tract that the patient cannot clear independently. It helps maintain airway patency and prevents complications such as aspiration pneumonia.

01:25Deglutition
7.5K
Swallowing, otherwise known as deglutition, facilitates the transport of food from the mouth to the stomach. It is a multifaceted process that involves both the tongue and the muscles of the throat and esophagus. Saliva and mucus aid in this process, which takes approximately 4 to 8 seconds for semi-solid or solid food and around 1 second for liquids or very soft food.
Swallowing can be divided into three stages: the voluntary phase, the pharyngeal phase, and the esophageal phase. Although the...

Here are the steps to accurately measure oral temperature using an electronic thermometer:
Step 1:
Start by practicing proper hand hygiene to prevent the spread of microorganisms.
Step 2:
Take the thermometer out of the charging unit, switch it on, and wait for the ready sign.
Step 3:
Gently slide the probe cover until a click is heard. This simple action prevents cross-contamination and ensures the correct placement of the probe cover.
Step 4:

01:26Assessment of the Mouth
1.5K
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.
