Clinical Trial Summary
Based on the changing understanding of carious biofilm development and caries progression,
Sealing carious dentine beneath a restoration deprives the caries biofilm of nutrients and
alters the environment sufficiently to slow or arrest lesion progression. This has the added
benefit of avoiding pulp exposure and subsequent treatment .The evidence base supporting the
biological approaches which include Hall technique has been steadily increasing in the last
few years. This has given rise to a growing trend towards a biological approach by Paediatric
dentists and has led to an increasing concern about the merits of conventional approach in
treatment of carious primary molars .
Description:
In orofacial development of the child, preservation of the primary dentition for as long as
possible is of great importance. As primary teeth maintain arch length and preserve
masticatory function. Unfortunately, the occurrence of cavitated caries lesions is still a
problem in developed and developing countries, with an increasing prevalence, particulary in
developing communities, conflicting with a general descending trend in prevalence worldwide.
The management of carious primary molars in children is problematic, additionally, primary
teeth commonly remain unrestored, especially in the younger children,The high levels of
dental disease in primary teeth, and its inadequate management, remains a major public health
issue for children, and one with a significant impact on their lives. In addition many
children are having to accept toothache as a part of their childhood. Set against this
background, there would seem to be some scope for the investigation of alternative approaches
to the management of carious primary teeth. If an alternative technique was found to be
simpler and more acceptable to children, their parents and general dental practitioners than
the conventional restorative approach, yet just as effective, then it might be more readily
applied in the general practice setting.
A novel, simplified method of using stainless steel crwons, the Hall Technique, has been
investigated. According to American Academy of Pediatric Dentistry, Hall technique calls for
cementation of a Stainless steel crown over a caries-affected primary molar without local
anesthetic, caries removal or tooth preparation, This technique was developed for use when
delivery of ideal treatment wasn't feasible.
As the crown is fitted with no occlusal reduction in the Hall technique, it was observed in
several studies that the occlusion would has been temporarily opened and returned to the
pretreatment situation within 2 weeks and no child reported Tempromandibular joint pain. This
goes in accordance with the study of Innes et al., as they stated that after placement of
stainless steel crowns using the Hall technique, the occlusion returns to the pretreatment
situation within 15-30 days. Also, Dr. Hall stated that the occlusion tended to equilibrate
by the next recall appointment and none of her patients reported Tempromandibular joint pain.
A published data from Dr Hall's practice records has indicated that Hall technique might have
similar survival rates to other, more conventional, restorative options currently being used
in Primary Care. In addition, avoiding the use of Local anesthesia and rotary instruments for
tooth preparation and caries removal might mean that the technique is less demanding of both
children and their dental team. The technique is therefore minimally invasive and can be
expected to cause less discomfort than conventional treatment approaches. This aspect could
be a considerable advantage as the Hall technique is a child centered approach and it is not
surprising that the first data published on patient perceptions of the hall technique are
promising. It was reported a clear difference in levels of discomfort, subjectively assessed
by the operators, between the Hall technique and a conventional treatment approach. The Hall
stainless steel crowns caused 'no discomfort' to 'mild discomfort' in comparison to the
conventional restorations. Several conducted studies showed that the majority of the
children, their caretakers and dentists expressed a preference for the Hall technique to the
conventional restorations.
The Hall Technique embraces changing concepts of managing dental caries, moving from the
dogma requiring its complete surgical excision, even at the expense of cavity size and pulpal
health, to the understanding that caries in dentine can be slowed, arrested, and possibly
even reversed, within a meticulously sealed environment. It is known that the microflora in
sealed carious dentine changes, with the predominating organisms no longer being cariogenic
having been sealed from the oral environment. This may be important in the apparent arrest of
caries progression.
Owing to its non invasive design, acceptance by patients and rate of restoration longevity,
the Hall technique maybe an improved treatment option to increase access to care, decrease
rates of untreated caries and provide a restoration that will allow for natural tooth
exfoliation.
In the last few years, conventional restorations including complete removal of carious tissue
with or without pulp therapy for the treatment of carious lesions in primary teeth have been
challenged and a more biological approach has been suggested. This has given rise to a
growing trend towards a biological approach by paediatric dentists and has led to an
increasing concern about the merits of the conventional approach and whether to retain this
treatment modality as the standard technique in restoring primary teeth or to adopt the
biological approach as the treatment norm.
