Summary
Across aesthetics-related clinical and translational research, a double-blind randomized trial showed superior medium-term relief of dentin hypersensitivity with bioactive glass or polyvalent metal toothpastes versus sodium fluoride varnish. A prospective phase 2 study demonstrated that three-fraction accelerated partial breast irradiation achieved excellent long-term cosmesis with minimal toxicity. A scoping review of cosmetic stature lengthening highlighted major gaps in validated patient-reported outcomes, urging standardization.
Research Themes
- Noninvasive management of dentin hypersensitivity
- Ultra-hypofractionated partial breast irradiation and cosmesis
- Standardizing patient-reported outcomes in cosmetic stature lengthening
Selected Articles
1. Metals, fluoride and bioactive glass on dentin hypersensitivity and quality of life: A 6-month double-blind randomized clinical trial.
In this double-blind RCT (51 patients; 241 teeth), all products reduced dentin hypersensitivity over 6 months, with both toothpastes outperforming sodium fluoride varnish at 3 months and Elmex Opti-namel maintaining superiority at 6 months for evaporative pain. Oral health-related quality of life improved modestly across groups.
Impact: Provides comparative clinical efficacy data for noninvasive DH treatments with validated outcomes, informing day-to-day decision-making in restorative/cosmetic dentistry.
Clinical Implications: For sustained DH relief, clinicians may preferentially recommend bioactive glass or polyvalent metal-containing toothpastes over sodium fluoride varnish, while setting expectations for modest OHRQoL gains.
Key Findings
- All tested products significantly reduced dentin hypersensitivity over 6 months (p < 0.001).
- For evaporative stimulus, both toothpastes outperformed NaF varnish at 3 months; Elmex Opti-namel remained superior at 6 months (p = 0.048).
- For tactile stimulus, Biomin F was less effective than NaF varnish immediately after application (p = 0.028), with no later between-group differences.
- Oral health-related quality of life improved in all groups, with overall improvement rated as low.
Methodological Strengths
- Double-blind randomized controlled design with multiple timepoints up to 6 months
- Use of both stimulus-specific VAS outcomes and validated OHIP-14 for OHRQoL
Limitations
- Modest sample size from a single trial and short (6-month) follow-up
- Product-specific comparisons may limit generalizability across formulations
Future Directions: Longer-term, multicenter RCTs comparing broader desensitizing technologies and dosing regimens with health-economic endpoints are warranted.
2. Three-Fraction External Beam Radiotherapy in Patients with Early Breast Cancer.
This single-institution phase 2 cohort (49 patients) found that three-fraction APBI (22.5 Gy over 3 days) achieved excellent/good cosmesis in 96% (physician-rated) and 92% (patient-rated) at 3 years, with minimal late toxicity and no local/regional recurrences at a median of 39 months.
Impact: Demonstrates feasibility and favorable cosmetic and oncologic outcomes of ultra-hypofractionated APBI, potentially reducing treatment burden while preserving aesthetics.
Clinical Implications: In carefully selected early breast cancer patients, a three-fraction APBI regimen may be considered to optimize convenience and cosmesis, pending comparative trials versus standard fractionation.
Key Findings
- Three-fraction APBI (22.5 Gy in 3 consecutive days) yielded excellent/good cosmesis in 96% (physician) and 92% (patient) at 3 years.
- Minimal toxicity: mostly grade 1 acute dermatitis; no significant late edema, induration, fibrosis, or pigmentation at 3 years.
- No local or regional recurrences at median 39 months; one distant relapse occurred at 46 months.
Methodological Strengths
- Prospective phase 2 design with predefined cosmetic endpoints and both physician- and patient-reported assessments
- Three-year follow-up with detailed acute and late toxicity profiling
Limitations
- Single-institution, single-arm cohort without randomization or comparator
- Modest sample size and selected low-risk population may limit generalizability
Future Directions: Randomized comparisons against standard hypofractionated whole-breast or partial-breast regimens, and incorporation of 3D cosmetic/functional assessments and cost-effectiveness analyses.
3. Measuring more than just centimeters: a scoping review of outcome measures in cosmetic stature lengthening.
In 20 CSL studies, 410 outcomes were reported but were heavily skewed toward physiological/clinical metrics (75%), with limited assessment of quality of life (25%) and frequent use of unvalidated satisfaction measures (55%). Social functioning was among the least reported domains, underscoring the need for standardized, validated PROs.
Impact: By mapping outcome-reporting gaps and emphasizing validated PROs, this review can recalibrate CSL research toward patient-centered endpoints and improve comparability across studies.
Clinical Implications: Clinicians and researchers should incorporate validated PRO instruments and a core outcome set capturing quality of life, psychosocial well-being, and function alongside traditional clinical metrics when evaluating CSL.
Key Findings
- Outcome reporting in CSL is dominated by physiological/clinical metrics (75%), with life impact outcomes comprising 21% and adverse events only 3%.
- Only 25% of studies assessed quality of life; 55% reported patient satisfaction, predominantly using unvalidated tools.
- Social functioning was among the least reported domains (15%), indicating underappreciated psychosocial sequelae.
Methodological Strengths
- Adherence to JBI and PRISMA-ScR standards with comprehensive multi-database search
- Systematic categorization using COMET taxonomy to benchmark outcome domains
Limitations
- Scoping review design without meta-analysis or formal risk-of-bias assessment
- Heterogeneity of instruments and reporting limits quantitative synthesis
Future Directions: Develop a CSL core outcome set with validated PROs (e.g., quality of life, social functioning) and implement standardized reporting to enable meta-analyses and guideline development.
