Guide to Diagnostic Services in Family Dentistry: Exam, X-ray, & More

Table of Contents

A shift towards proactive patient care requires a foundation in diagnostic dental services in family dentistry. This includes comprehensive oral examinations, digital radiography (bite-wing and panoramic X-rays), periodontal assessments employing probing depths and bleeding on probing (BOP) measurements, saliva testing for bacterial composition, and temporomandibular joint (TMJ) evaluations. But beyond the dental services are skilled and knowledgable family dentists to diagnose and conduct the procedures.  For quality dental care, a reputable ‘family dental near me’ in Maple Ridge can make all the difference.  

Dental Examinations

A 2020 study published in the Journal of Dentistry investigated the effectiveness of dental examinations in identifying early signs of caries (cavities) in children. The study found that visual inspection combined with bitewing X-rays during dental exams effectively detected invitations. This is particularly true in approximal surfaces, where detection can be challenging for a dental team. A dentist meticulously inspects all aspects of the oral cavity in a visual inspection, including:
  • Examining the teeth for signs of decay, fractures, wear and tear, enamel erosion, and tooth misalignment.
  • Assessing the gums for inflammation, redness, bleeding, and recession (gum loss).
  • Evaluating the tongue or oral mucosa for discoloration, lesions, and potential signs of oral cancer.
  • Inspecting the throat for abnormalities.

Oral Health Assessment

A medical and dental history review of the new patients provides valuable insights into potential risk factors for oral health problems. This includes:
  • Existing medical conditions
  • Dental visits
  • Medications
  • Allergies
  • Previous dental treatments (i.e. cosmetic dental services)
  • Oral hygiene practices

Extraoral vs Intraoral Examinations

During an extraoral examination, a Maple Ridge dentist examines the head and neck for facial asymmetry, swelling, tenderness, or abnormalities in the temporomandibular joint (TMJ) for optimal dental health. In the intraoral examination, it focuses on the inside of the mouth, including:
  • Tooth assessment for decay, fractures, wear patterns, tooth mobility, and potential malocclusion (misalignment) during the dental treatment.
  • Periodontium evaluation of the gums for inflammation, bleeding on probing, recession (loss of gum tissue), and probing pocket depths after cosmetic dentistry services.
  • Inspect oral mucosa for lesions, ulcers, discolouration, and potential signs of oral cancer.
  • Tongue examination for texture, colour, and any abnormalities.

Diagnostic Tests

Influenced by the results of the clinical examination, additional diagnostic tests may be employed, such as:
  • Dental X-rays: Offer insights into the underlying structures of the teeth and jawbone. It aids in the detection of cavities, bone loss, teeth whitening, and potential orthodontic issues.
  • Salivary Flow Tests: Measure the quantity and quality of saliva, which can indicate xerostomia (dry mouth), a condition that can increase the risk of cavities and gum disease.

X-rays in Oral Cancer Screenings

A research from the Oral Surgery, Oral Medicine, Oral Pathology, and Oral Radiology journal investigated the effectiveness of panoramic X-rays in detecting dental cancer. The study found that panoramic X-rays are helpful in identifying suspicious lesions requiring comprehensive dental care for patients of all ages.
X-Ray Type Technique Application
Bitewing Small sensor/film holder placed in the mouth, and the patient bites down Visualize interproximal surfaces of posterior teeth for caries detection, assess alveolar bone integrity, and monitor crestal bone levels for quality dental care
Panoramic Panoramic machine rotates around the head Capture a broad image of the entire jaw, including teeth, sinuses, and TMJs; evaluate wisdom teeth development, jawbone integrity, potential orthodontic issues, bony pathology; useful for initial examinations in a dental clinic
Periapical Small sensor/film holder positioned against teeth and gums Dental surgeons capture high-resolution images of one or two teeth and surrounding bone; diagnose complex root fractures, monitor root canal treatments, assess periodontal bone loss, evaluate periapical pathology

Periodontal Health

Periodontal disease, or gum disease, is a long-term inflammatory condition that attacks the tissues supporting your teeth. Left untreated, it can not only cause tooth loss but also potentially harm your overall health.

Components of a Periodontal Assessment

  • Dentist inspect the gums for signs of inflammation, including redness, swelling, and bleeding on probing (BOP). Changes in gum colour or texture are indicative of gingivitis.
  • A periodontal probe measures the depth of the sulcus (space) between the tooth and gum. Healthy sulcus depths range from 1-3 mm. Increased probing depths can indicate gum recession (loss of gum tissue) and potential bone loss, suggesting more advanced stages of periodontal disease.
  • Gently probing the sulcus with a periodontal probe should not cause bleeding. BOP is a clinical sign of inflammation and potential attachment loss between the tooth and gum.
  • Maple Ridge dentists evaluate the patient’s oral hygiene practices, including brushing and flossing techniques. Plaque accumulation on the teeth is a significant risk factor for gum disease.

Saliva Testing for Bacterial Content

Techniques for Saliva Testing

Culture Methods Traditional culture methods involve collecting saliva samples and growing bacteria on specific media in a laboratory setting.
Molecular Techniques Advanced techniques like polymerase chain reaction (PCR) and next-generation sequencing (NGS) analyze bacterial DNA present in saliva.  Allows for a more comprehensive evaluation of the bacterial composition of the oral microbiome.
  In a study on saliva testing for bacterial content, researchers investigated the presence of ten bacteria associated with oral diseases in saliva samples from 214 people. Eight out of the ten bacteria tested were significantly higher in people with periodontitis compared to healthy individuals.  These bacteria included:
  1. C. rectus
  2. T. forsythia
  3. P. gingivalis
  4. S. mutans (also higher in caries compared to healthy)
  5. F. nucleatum
  6. T. denticola
  7. P. intermedia
  8. Oral Lactobacilli

Occlusal Analysis

A dentist performs an occlusal analysis, also called a bite analysis, to gauge how upper and lower teeth interact in both stationary and moving positions. A healthy bite ensures proper distribution of forces during chewing, speech, and swallowing, promoting optimal oral health and function.

The Power of T-Scan

Digital occlusal analysis, with tools like T-Scan, offers a more comprehensive understanding of a patient’s bite and its impact on oral health. It goes beyond the static information provided by articulating paper. It utilizes sensors placed in the mouth to capture real-time data on:
  • Force: T-Scan measures the level of force exerted on individual teeth during chewing. Allows dentists to identify areas of excessive force that could potentially damage restorations like crowns, bridges, or veneers.
  • Timing: T-Scan reveals the sequence in which teeth come together, helping dentists assess occlusal stability and identify potential issues like premature contacts that can contribute to discomfort or TMJ dysfunction.
By providing a more detailed picture of a patient’s bite, T-Scan allows dentists to:
  • Optimize implant placement and loading protocols.
  • Ensure proper tooth alignment during clear aligner therapy.
  • Minimize the need for remakes of crowns and other restorations by ensuring balanced occlusal forces.

TMJ Dysfunction

The temporomandibular joint (TMJ) enables the complex movements essential for eating, speaking, and facial expressions. However, dysfunction of the TMJ leads to a range of debilitating symptoms.
Examination Type Description Focus
Subjective Examination Gathering detailed information about the patient’s experience
  • Symptom onset and location (pain, clicking)
  • Mechanism of injury (trauma, jaw injuries, dental procedures)
  • Severity and irritability of symptoms
  • Aggravating and easing factors
  • Joint noises (clicking, popping, grating)
  • Medical history (fractures, dental work, bruxism)
  • Referral area questions (neck pain, headaches, dizziness)
Objective Examination Physically evaluating the TMJ and associated structures
  • Observation (facial asymmetry, swelling, jaw posture)
  • Palpation (tenderness, restricted movement)
  • Range of motion (jaw opening, closing, lateral movements)
  • Cervical spine assessment (posture, range of motion)

Special Tests and Outcome Measures

  • The Tongue Blade Test is a simple test assessing the presence of pain or discomfort caused by a sudden stretch on the superior joint capsule.
  • The Oral Behaviors Checklist (OBC) is a tool for identifying behavioural factors, such as nail biting or pen chewing, that may contribute to TMJ dysfunction.

Frequently Asked Questions

No, X-rays are not required at every visit. The frequency depends on your individual needs and risk factors. For example, healthy adults with no recent dental problems might only need X-rays every few years, while individuals with a history of cavities or gum disease might require them more often. Your dentist will use their clinical judgment and discuss the use of X-rays (e.g., bitewing X-rays for interproximal caries detection) based on your specific situation.

  • Dental Cleaning (Prophylaxis): Hygienists wield specialized tools to combat plaque and tartar, the enemies of clean teeth. This helps prevent gum disease and ensures optimal oral health.
  • Dental Exam: A dentist performs a thorough examination of your teeth, gums, and oral tissues. This may include checking for cavities, gum disease, and signs of oral cancer and evaluating your bite. Depending on your needs, X-rays may be included.

Obstetricians and Gynecologists advise postponing non-essential X-rays during pregnancy, particularly in the first trimester. If X-rays are deemed absolutely necessary, your dentist will take all precautions to minimize radiation exposure to your abdomen, such as using lead shielding for your dental goals.
