Summary
A case report shows successful root coverage using an acellular dermal matrix (ADM) and tunneling. Over 90% of recession defects were resolved, with creeping attachment observed within six months.
Area of Science:
- Periodontology
- Regenerative Dentistry
Background:
- Gingival recession poses a significant clinical challenge.
- Root coverage procedures aim to restore lost soft tissues and improve aesthetics.
- Acellular dermal matrix (ADM) is a common biomaterial for root coverage.
Observation:
- A 50-year-old male patient presented with approximately 6 mm of gingival recession on teeth #6–#11.
- The patient underwent root coverage using an acellular dermal matrix (ADM) with a tunneling technique.
- Clinical measurements and photographs documented the treatment outcomes.
Findings:
- Over 90% root coverage was achieved at all treated sites after 24 months.
- Creeping clinical attachment was observed starting at 6 months post-therapy on teeth #7–#11.
- Delayed creeping attachment is likely related to ADM vascularization time and thickness.
Implications:
- This case highlights the efficacy of ADM combined with tunneling for substantial root coverage.
- The findings suggest that creeping attachment is a significant factor in long-term root coverage success.
- Understanding ADM vascularization dynamics can optimize treatment planning for periodontal regeneration.

01:22Creep in Concrete
1.2K
Creep refers to the time-dependent increase in strain under a sustained load, excluding other time-dependent deformations associated with shrinkage, swelling, and thermal expansion in concrete. The primary mechanism behind creep involves the loss of physically adsorbed water from the calcium silicate hydrate within the hydrated cement paste. This process is further exacerbated by concrete's non-linear stress-strain relationship, microcrack development in the interfacial transition zone, and...

01:28Factors Affecting Creep
431
In normal-weight aggregate concrete, the hardened cement paste is the primary contributor to creep, whereas the aggregates, being stiffer than the cement paste, are more resilient to stress-induced deformation. The stiffness of the aggregates is defined by their modulus of elasticity, and the more voluminous they are in the concrete, the less it will creep.
Further, the water/cement ratio is critical, as a lower ratio increases concrete strength, thus reducing creep. The strength of the...

01:25Effects of Creep
411
Creep in concrete, the gradual deformation under prolonged stress, significantly impacts the integrity of structures. For reinforced concrete beams, it can be a vital design consideration, as it increases deflection, sometimes necessitating additional design measures. In columns, especially slender ones under eccentric loads, creep can cause buckling, compromising their stability. However, creep can be beneficial in indeterminate structures by mitigating stresses that arise from shrinkage,...

Vascular plants, which account for over 90% of the Earth’s vegetation, all undergo primary growth—which lengthens roots and shoots. Many land plants, notably woody plants, also undergo secondary growth—which thickens roots and shoots.
