Saliva has moved from the byproduct of the examination to the fluid that the modern practice can read, and the diagnostics that the salivary sample supports now reach from the caries risk to the periodontal inflammation and beyond. The fluid is easy to collect, safe to handle, and rich in the pro...

The narrow alveolar ridge is the common obstacle that the implant plan meets in the healed posterior site, and the ridge split technique is the approach that widens the crest without the block graft and the second surgical site. The technique uses the viscoelastic property of the bone, and the co...

The resin-bonded bridge is the conservative alternative to the conventional fixed prosthesis, and its place in the modern practice has widened as the adhesive dentistry matured. The prosthesis replaces the missing tooth with the minimal removal of the enamel from the abutment, and the retention i...

The systemic antibiotic has a defined and a narrow place in the periodontal therapy, and the clinician who respects its limits uses it well while the clinician who reaches for it routinely erodes both the result and the antibiotic stewardship. The mechanical debridement remains the foundation of ...

The bond failure of the bracket is the interruption that the fixed orthodontic treatment can tolerate in the small number but not in the pattern, and the clinician who understands the cause reduces the frequency that the repeated rebonding records. The failure that recurs on the single tooth poin...

The prescription pad is one of the most common sources of the oral complaint that the patient brings to the dental office, and the clinician who does not think of the medication may spend the appointment treating the symptom that the drug created. The list of the agents that affect the mouth grow...

The intraoral scanner has moved from the novelty of the early adopters to the standard equipment of the modern prosthodontic practice, and the comparison with the conventional impression has become a daily question rather than an academic one. The scanner captures the surface of the teeth and the...

The endodontic retreatment is the second chance that the tooth receives when the initial treatment fails to resolve the infection or the symptoms, and the procedure is both more demanding and more rewarding than the primary treatment. The clinician who retreats the tooth encounters the filling ma...

The access preparation is the gateway of every root canal treatment, and it is the step at which the outcome of the case is most often decided, for good or for ill. A well-designed access straightens the canal system, removes the coronal obstruction, and allows the instruments and the irrigants t...

The restoration that the laboratory returns is only as good as the information that the clinician sends, and the communication between the dentist and the technician is the step that determines whether the crown, the veneer, or the bridge meets the expectation of the patient. The shade, the form,...

The posterior maxilla is the most demanding site in implant dentistry, because the pneumatized maxillary sinus frequently leaves the clinician with less bone than the implant requires. Maxillary sinus augmentation, the surgical procedure that raises the sinus floor to create vertical bone, has be...

The rubber dam is the oldest and still the most effective isolation device in restorative dentistry, and its reputation as an inconvenient extra step survives among practitioners who have never measured the time it actually saves. The dam isolates the field from the saliva, the tongue, and the ch...

The margin is the most vulnerable line in fixed prosthodontics, because it is the only boundary between the prepared tooth, the restoration, and the oral environment that the clinician cannot fully seal by effort alone. A restoration that fits seamlessly at the margin resists leakage, caries, and...

The masticatory system is built for function, yet much of its damage comes from habits that serve no purpose. Parafunctional habits, the clenching, the grinding, and the tongue pressing performed outside of normal function, sit behind much of the tooth wear, the temporomandibular pain, and the my...

Chronic mouth breathing in the growing child is seldom a dental problem in origin and almost always a facial one in consequence. The child who sleeps with the mouth open bypasses the physiologic benefits of nasal respiration, and the posture that the airway forces upon the tongue, the mandible, a...

The immediate denture is the prosthesis placed on the day the teeth are extracted, sparing the patient the edentulous interval the conventional denture imposes and preserving the occlusal vertical dimension, the facial support, and the appearance through the transition. The clinical literature ha...

The Class III malocclusion in the growing child carries a special urgency, because the maxillary deficiency that marks the pattern does not correct itself and the window for the growth-modifying treatment closes with the skeletal maturity. Elastic protraction, the orthopedic therapy that pulls th...

The denture is the only prosthetic device in medicine that its owner is expected to wear daily and to clean personally, yet it is also the device most commonly neglected until the signs of disease appear. A biofilm that forms on the acrylic base within hours is a reservoir of candida and bacteria...

The complete denture stands or falls on the impression, because the impression determines how well the base follows the mucous membrane and how evenly the occlusal load is distributed across the basal seat. For a century the profession has argued about whether the impression should record the muc...

The all-ceramic crown has moved from a niche product to the default restoration for the anterior single tooth in a single clinical generation, driven by patient demand for metal-free appearance and by materials that now survive functional loading as reliably as their metal-ceramic predecessors. A...

The vertical root fracture is among the most frustrating diagnoses in dentistry: the tooth is often restored, asymptomatic for years, and then develops a sinus tract or a bone loss that no retreatment seems to cure. The fracture is a complete or incomplete longitudinal split of the root, frequent...
