Study summary

Context: Acromegaly is the rare condition (3 to 4 new cases per million per year) due to Growth Hormone (GH) overproduction by a somatotrope pituitary adenoma, resulting in Insulin Growth Factor 1 (IGF-1) excess. Consequently, many tissues of the organism become hypertrophied. Hypertrophy of gingival and dental tissues can lead to alteration of oral health. However, there are very few published data concerning oral impact of acromegaly.

Objective: To do the most accurate clinical and radiological state of oral manifestations in the series of prevalent acromegaly patients followed in the endocrinology service of the CHU of Clermont-Ferrand.

Read the detailed description

Context/ study relevance: Acromegaly is a rare condition (3 to 4 new cases per million per year) due to Growth Hormone (GH) overproduction by a somatotrope pituitary adenoma, resulting in Insulin Growth Factor 1 (IGF-1) excess. Consequently, a dysmorphic syndrome prevailing at the level of face and extremities progressively develops associated with potentially severe general manifestations (cardiovascular, respiratory and metabolic complications). Oral manifestations of acromegaly are not well known, there is very few published data on this topic and a controversy about the existence of a parodontal disease, i.e. the presence of gingival sulcus deepening which can lead to tooth loss. IGF-1 excess could lead to gingival hypertrophy and then to gingival sulcus deepening. Otherwise, the dental cementum, the only dental tissue which can grow during all lifetime, could be influenced by an excess of IGF-1. It is likely that acromegaly is associated with pathological cementum hypertrophy.

Objective: To do the most accurate clinical and radiological state of oral manifestations in the series of prevalent acromegaly patients followed in the endocrinology service of the CHU of Clermont-Ferrand. Investigator will take a special interest in parodontal status i.e. the state of supporting tissues of the teeth and structural anomalies of dental cementum.

As secondary objective, investigator would make a histological characterization of gingival and dental (cementum) tissues when a surgical treatment of the oral condition is required. Investigator will search hypertrophic anomalies linked with GH/IGF-1 excess.

Material and methods: This is an observational, descriptive, cross-sectional, monocentric study conducted in the endocrinology/diabetology service of Clermont-Ferrand University Hospital (CHU), in France, where a series of about 70 prevalent acromegaly patients is annually followed. The participants will be adult acromegaly patients followed in this service, with proven diagnosis of acromegaly or previous acromegaly. They will be excluded of the study if they are totally toothless, if they take a medication associated with gingival hypertrophy if they are in a medical or chirurgical condition interacting with oral health so that the oral evaluation is not reliable or if there is no possibility of written informed consent. For each participant, investigator will collect demographic data and history of the pathology including previous and actual complications, biological tests results, imaging exams results and treatments. The participants will answer 3 questionnaires: AcroQol (quality of life in acromegaly patients), GOHAI (General Oral Health Assessment Index) and EPICES (evaluation of precariousness). The primary outcome will be a quantitative assessment of the oral health of the acromegalic patients with detailed assessment of 3 criteria:

  • Depth of gingival sulcus measured for of all teeth
  • CAO index (number of teeth with cavity or obturation or missing)
  • Thickness of dental cementum on orthopantomogram and all other abnormality on this exam.

The secondary outcome will be the histological analysis of gingival and dental tissues if available.

All these measures will be taken during a routine odonto-stomatological consultation, part of the annual pathology evaluation at the endocrinology/diabetology service.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. oral health of acromegal patients

    the periodontal status would be determinate by measuring the depth of gingival sulcus with a graduated periodontal probe on the four dental faces (mesial, distal, vestibular and lingual), on each tooth present in the mouth.

    Time frame: at day 1 (during the odonto-stomatological consultation)

Secondary outcomes

  1. study of the dental cementum

    the thickness of dental cementum would be measured on orthopantomogram. This characteristic could determinate the presence or not of hypercementosis

    Time frame: at day 2 (24h after receipt of sample)

  2. Determinate the CAO index

    The CAO index could be determinate by counting the number of teeth with cavity or obturation or missing

    Time frame: at day 2 (24h after receipt of sample)

  3. Analysis of pathological gingival tissues

    : if a gingival hypertrophy is determinate, a gingivectomy will be carried out and the tissue will be sent to the Anatomo-pathology laboratory to determinate its histological characteristics

    Time frame: at day 2 (24h after receipt of sample)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 17, 2018, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
