By Ana Espino | Published on March 4, 2026 | 3 min readFear of blood and pain represents a major
barrier to dental care in children. This often underexpressed preoperative
anxiety negatively affects therapeutic adherence and has a lasting impact on
the perception of future care. In pediatric oral surgery, many
procedures—extractions, biopsies, or excision of benign lesions—are associated
with visible bleeding, which can heighten apprehension and negatively influence
the operative experience.
The
conventional scalpel, historically regarded
as the reference tool because of its precision and ease of use, nevertheless
presents limitations in pediatric practice. Intraoperative bleeding can reduce
visibility of the surgical field, prolong procedure time, and increase
postoperative edema or discomfort. These technical and psychological
constraints have encouraged the development of so-called “
bloodless” techniques
aimed at optimizing hemostasis while minimizing tissue trauma.
The review published in 2025 in the Journal
of Pharmacy and Bioallied Sciences analyzes the mechanisms of action,
clinical indications, as well as the benefits and limitations of the main
approaches used to achieve a bloodless operative field in pediatric dentistry:
electrosurgery, laser therapy, cryosurgery, and Apexum.
What if surgery became invisible to the child?
The authors present a
narrative review of
contemporary techniques that create a bloodless operative field in pediatric
dentistry. The objective is to assess their mechanisms of action, clinical
indications, and benefit–risk profiles.
Electrosurgery, introduced in the early
twentieth century, relies on the application of high-frequency electrical
current that enables simultaneous cutting and coagulation of soft tissues. It
is indicated for gingivectomy, frenectomy, exposure of impacted teeth, and
biopsy procedures. It provides
effective hemostasis, reduces operative time,
and limits postoperative discomfort. However, it is contraindicated in patients
with pacemakers and in certain procedures close to bone tissue.
Lasers, introduced into dentistry in the 1960s,
produce a photothermal reaction that induces protein coagulation above 60°C and
tissue ablation above 100°C. They are used for benign mucosal lesions, gingival
hyperplasia, mucoceles, and aesthetic procedures. Their precision reduces
peripheral necrosis, improves operative visibility, and decreases postoperative
pain. Nevertheless, caution is required in cardiac and immunocompromised
patients.
Cryosurgery, based on the cytotoxic effect of
extreme cold, allows controlled destruction of benign lesions such as fibromas,
leukoplakia, or lichen planus. It is associated with a
low rate of secondary
infection, minimal scarring risk, and generally does not require local
anesthesia. However, certain systemic conditions constitute formal
contraindications.
Finally, the
Apexum technique represents a
minimally invasive approach in endodontics. It enables removal of inflamed
periapical tissues through the root canal, without surgical flap elevation or
suturing. This method promotes faster healing and reduces postoperative pain
while preserving the benefits of traditional apical surgery.
A paradigm shift in pediatric dentistry
Pediatric oral surgery faces a dual imperative:
ensuring therapeutic efficacy while preserving the child’s emotional balance.
Control of intraoperative bleeding is not merely a technical issue but also a
major lever for reducing anxiety and improving treatment acceptance.
This review aimed to evaluate contemporary
approaches designed to limit or eliminate bleeding in pediatric practice. The
analyzed data indicate that
electrosurgery, lasers, cryosurgery, and the Apexum
technique improve operative field visibility, ensure effective hemostasis, and
reduce tissue trauma. These benefits translate into decreased postoperative
discomfort and an improved overall clinical experience.
Although their use requires careful case
selection and appropriate technical expertise, these technologies illustrate
the shift toward
less invasive and better-tolerated pediatric surgery. In the
long term, their rational integration may enhance treatment adherence, improve
procedural safety, and sustainably optimize clinical outcomes in pediatric
dentistry.
