From Fear to Fragrance The Neuroscience of Scent and Patient Experience in Dentistry In a dental office, smell can significantly sway a
• Chamomile (Roman and German): Both types of chamomile have calming properties, but Roman chamomile is noted for its gentle and restorative effects. • Frankincense: This woody and spicy scent can help slow breathing and reduce stress and is often used for grounding and relaxation. • Ylang Ylang: This sweet, floral scent can help reduce anxiety and lower blood pressure and heart rate. • Sandalwood: Sandalwood is grounding and helps quiet the mind and reduce nervous tension. • Clary Sage: This herbaceous scent has sedative properties that may help induce relaxation and calmness. • Rose: Rose oil’s sweet, floral scent can help reduce stress and anxiety and promote emotional well-being. • Vetiver: Vetiver is known for its grounding and centering properties, helping to reduce overthinking and promote focus. • Neroli (Orange Blossom): This light, sweet,
the thalamus, olfactory information bypasses this relay station and heads straight to the amygdala, the brain region involved in processing emotions, and the hippocampus, which is crucial for memory. This direct pathway explains why smells evoke immediate emotional responses. An unpleasant dental odor might unconsciously trigger anxiety from past experiences, while a calming scent can foster positive associations and relaxation. Therefore, dental professionals should be mindful of the olfactory environment they cultivate. Strategically using subtle, pleasant scents can create a more welcoming and reassuring atmosphere, ultimately improving patients’ experience. The following scents are known to have calming effects on the nervous system: • Lavender: Lavender is believed to interact with neurotransmitters in the brain to promote calmness and improve sleep quality. • Bergamot: This citrusy oil has been shown to reduce stress, improve mood, and lower heart rate and blood pressure.
patient’s experience. A clean, subtly minty aroma can instill a sense of hygiene and care, easing anxieties. Conversely, the scent of harsh chemicals or a sterile, odorless environment can inadvertently trigger unease. The neuroscience behind this lies in the intricate connection between our olfactory system and the brain’s emotional centers. When odor molecules enter the nasal cavity, they bind to olfactory receptors. Unlike other senses, which are first processed by
and citrusy floral scent is calming, soothing, and uplifting, potentially relieving stress and anxiety. UNMASKING FAILURE Best Practices for Diagnosing Failing Dental Implants
• Peri-implant Soft Tissue Health: Even without bone loss visible on radiographs, inflammation or changes in the soft tissues surrounding the implant are red flags. Persistent BOP or increased probing depths warrant close monitoring. • Periapical Health: While less
Maintaining dental implant health is crucial for long-term success. While X-rays and CT scans are essential, relying solely on them can delay diagnosis. A combined clinical and radiographic approach is best practice. The initial stages of implant evaluation involve a thorough patient history. Asking about pain (even subtle discomfort), changes in bite, swelling, or mobility (even perceived movement) can provide vital clues. Also, always review implant history, complications, hygiene habits, and the patient’s overall health. Clinical examination is equally critical. Visual inspection of the peri-implant tissues can reveal inflammation, redness, recession, or suppuration. Gentle probing around the implant helps assess the peri-implant pocket depths and detect bleeding on probing (BOP), an early sign of peri-implantitis. Implant mobility should also be evaluated. While significant mobility is a late sign of failure, subtle movement may be detected with careful manipulation. Now, what about when radiographs appear normal? This is where a keen clinical eye and astute questioning become even more important. In these situations, consider the following. • Patient Symptoms: Never dismiss patient complaints, even if imaging is clear. Persistent discomfort, pressure, or a change in how the implant feels during function can be significant. • Functional Assessment: Evaluate the implant’s function. Is the patient experiencing any difficulty chewing or biting? Are there any occlusal discrepancies that might be overloading the implant?
common for implants, rule out any periapical pathology that might indirectly affect the implant’s stability. • Advanced Diagnostic Tools: In
some cases, dynamic loading tests or resonance frequency analysis (RFA) devices can provide objective data on implant stability even when radiographs are inconclusive.
These tools can detect subtle changes in implant osseointegration. Diagnosing implant failure without
radiographic signs requires a holistic approach. Combining patient history, meticulous clinical examination, and diagnostic tools improves early detection and timely intervention to support the long-term success of dental implants.
