About

Oral health is defined as the state of being free from dental or periodontal diseases and discomfort of oral cavity. WHO considers that oral hygiene is a major public health problem whatever the countries (developed, developing, and underdeveloped).

The two main local medical problems are dental caries and periodontal diseases. Without appropriate treatments, both diseases can lead to local functional and esthetic damages, and can also have some negative repercussions on health.

Studies showed that there are great social disparities among people concerned by oral health issues. People in vulnerable situations (homeless and low incomes people, refugees) had less recourse to dental care. Those who consult do it less often and later. Reasons are mainly cost related, but also people in vulnerable situation don't perceive dental care as an important matter and don't know where and how to ask for help for having dental care.

PASS (french acronym for "Office of Access to Healthcare") departments, setting in both private and public health institutions, are intended to facilitate the access to care and the support of people in vulnerable situations, and their accompaniment in the steps necessary for the recognition of their rights.

Nurses of the Annecy PASS department had developed a questionnaire called "healthplan guide" that aim at helping them to screen and identify people with dental diseases among those in vulnerable situation, and to sensitize them about the importance of oral hygiene and how to improve it. This questionnaire is use in daily practice.

This study hypothesizes that more patients will be sensitized to benefit a dental examination in a dental practice if nurses use the "healthplan guide" questionnaire combined with an oral and dental evaluation.

Full description

Oral health is defined as the state of being free from dental or periodontal diseases and discomfort of oral cavity. WHO considers that oral hygiene is a major public health problem, as regard to number of people involved and the consequences either local (pain, functional deteriorations, teeth loss) or general (decreased quality of life, lower health status and increased mortality rate).

The two main local medical problems are dental caries and periodontal diseases ; among adults this is a major public health problem whatever the countries. Furthermore, the cost of these diseases is high, for example ranking fourth in developed countries health costs.

Dental caries is the most prevalent disease worldwide. The local production of organics acids by cariogenic bacteria located in the dental plaque, leading to the reduction of local pH, is responsible for enamel demineralisation and tooth decay. The local production of organic acids is due to the metabolism of fermentable sugars by bacteria of the dental plaque, saccharose being considered as the most cariogenic one. Dental caries occur when pH modification is durable. First, tooth decay affects only enamel and can be cured if appropriate measures favorising remineralisation are used. Second, when the enamel is totally destroyed, the hole inside dentin is irreversible and requires specific care.

Periodontal disease is also due to bacterias located in the dental plaque, with first, a local inflammatory reaction in the soft tissues of the tooth (gum and alveolar bone) that, second, lead to their destruction. This is a long lasting course disease.

Without appropriate treatments, both diseases can lead to local functional and esthetic damages, and can also have some negative repercussions on health, putting the patient at a higher risk of infectious endocarditis, cardiovascular or bronchopulmonary diseases, preterm deliveries, pre-eclampsias, poor control of diabetes, or increased rheumatoid arthritis exacerbations.

Furthermore, some other diseases are likely to favor bucco-dental diseases, such as diabetes, or immunosuppressive diseases for example AIDS.

Some medicines, particularly those inducing xerostomia increase the development of bucco-dental diseases. Alcohol and tobacco consumption is known to be an important risk factor.

Studies showed that there are great social disparities among people concerned by oral health issue. For example, people with low incomes have more missing teeth, dental caries needing care or avulsions, parodontal diseases and deficient oral hygiene. People in vulnerable situations (homeless and low incomes people, refugees) have less recourse to dental care. Those who consult do it less often and later. Reasons are mainly cost related, but also people in vulnerable situation don't perceive dental care as an important matter in absence of pain and don't know where and how to ask for help for having dental care.

In France, in 1998 an act (Loi d'orientation du 29 juillet 1998 "relative à la lutte contre les exclusions") implemented the permanent access to health care for people in vulnerable situations and created departments called PASS (french acronym for "Office of Access to Healthcare"). These structures, setting in both private and public health institutions, are intended to facilitate the access to care of people in vulnerable situations, and to support them throughout all the steps required to obtain recognition of their rights.

PASS-Annecy department was created in 2003 in Annecy hospital. In 2010, the French High Authority for Public Health published some recommendations on caries prevention; development of dental consultations for people in vulnerable situation in local structures such as PASS were encouraged.

After severe infections (endocarditis and face cellulitis) in two homeless people in Annecy hospital, nurses of the Annecy PASS department had developed a questionnaire called "healthplan guide" that aim at helping them to screen and identify people with dental diseases among those in vulnerable situation, and to sensitize them about the importance of oral hygiene and how to improve it. This questionnaire is use in daily practice. Nevertheless, despite sensitization with the "healthplan guide" use, few people among vulnerable one's went to the dental practice after the nurses made them an appointment.

This study hypothesizes that more patients will be sensitized to have a dental examination in dental practice if nurses will do an oral and dental evaluation combined with the use of the "healthplan guide" questionnaire.

Trial design

Primary purpose: Prevention

Allocation: Randomized

Interventional model: Parallel Assignment

Masking: Single Blind

---

183 participants in 2 patient groups

Healthplan guide alone

No Intervention group

Description:

Nurse applies the daily-practice questionnaire called "Healthplan guide" to screen and identify people with dental diseases, among those in vulnerable situation, and to sensitize them about the importance of oral hygiene and how to improve it. After that, the nurse has to state if, from her/his point of view the patient needs dental care or not. Whatever the answer, the nurse makes an appointment to a dental practice, in the 30 following days, and gives it to the patient with a free bus ticket. Randomization is done at that time. The dentist, blinded of the patient's group, makes a dental exam and says if the patient needs dental care or not. If care are indicated, they will be organized but outside this trial.

Oral and dental evaluation

Experimental group

Description:

After application of the "Healthplan guide", nurse statement of the need of dental care or not, making of an appointment to the dental practice and gift of a free bus ticket, if the patient is randomized in the experimental group, the nurse completes the evaluation with a mouth inspection in order to count missing, coloured, injured teeth, and evaluate dental plaque, halitosis, inflammatory gums, mucosal injuries, low masticatory surface. At the end of this exam, the nurse has to state again if, from her/his point of view the patient needs dental care or not. The dentist, blinded of the patient's group, makes a dental exam and says if the patient needs dental care or not. If care are indicated, they will be organised but outside this trial.

Other: Oral and dental evaluation
