Henri Lentulo (born November 17, 1889 in Nice , † January 27, 1981 in Gap ) was a French doctor of Italian descent and a pioneer of dentistry . He dedicated his whole life to dentistry and a large number of his treatment techniques are still used by dentists around the world to this day.

Life

childhood and education

Lentulo spent his childhood in Nice with six younger siblings and graduated from primary school in 1902 with a brilliant certificate. From 1904 to 1907 he completed an apprenticeship as a dental technician in Marseille . During these years he also dealt with socialism . In October 1908 he became laboratory manager at a dentist in Calais . After a change in the training regulations for dentists (duration now 3 to 5 years) Lentulo went to Paris in February 1909 to prepare for his studies. In September this year he began his studies at the Ecole Dentaire and put it in 1912 in Turin , where he in the same year at the Royal University his exams made.

Henri Lentulo as a Foreign Legionnaire in the First World War

First World War (1914 to 1918)

His socialist conviction led Lentulo to join the French army after the murder of Jean Jaurès (in July 1914) with the outbreak of World War I in August 1914 . Because he had Italian citizenship , he was a " second class legionnaire ". In October of the same year he became a medical assistant in the 4th  Infantry Regiment of the Legione Garibaldina of General Peppino Garibaldi . After several military posts ( Orléans (April 1915), Laon (June 1915), Saint-Dié (July 1915), Champagne (October 1915)) he fought in Verdun in June and July 1916 and was assigned to the department of in October 1916 Maxillofacial surgery transferred to the Montpellier hospital .

Henri Lentulo, 1936 in Vienna

In March 1925, Lentulo received French citizenship . At about the same time he began his research on tooth filling materials . In 1928 he presented his spiral-shaped root filler (later named after him) for the mechanical filling of root canals . He contacted the Maillefer company in Ballaigues ( Switzerland ) in order to industrially manufacture and market the root filling paste. There was immediate success. The patent was granted on April 7, 1928 . A patent has also been applied for in the USA . In 1930 Lentulo became a member of the École de Paris in Paris as a prosthodontist and in 1931 head of the clinic.

In August 1931, Lentulo was rapporteur at the 8th Congress of the FDI World Dental Federation (FDI). His topic: "The opening and closing of the root canals".

In August 1936 he again represented the École de Paris at the 9th FDI Congress in Vienna . His work and his lecture “Treatment of the Root Canals” received international recognition.

1939 to 1981

As a war veteran of the First World War, Lentulo was deeply shaken by the debacle of the French army in 1939.

From 1943 to 1956 he was a member of the board of directors and the management of the École de Paris and took this task very seriously.

In November 1948 Lentulo was appointed "ex officio" as President de la Société Odontologique de Paris (President of the Paris Society of Dentistry) . In 1951 he founded the l'Association d'Enseignement d'Odonto-Stomatologie (Society for the Training of Dentists) and became its President.

Although he refused to co-found the journal Actualités Odonto-Stomatologiques (AOS) in 1948 , he published numerous articles for this specialist body.
In 1952 the most important lecture of his career appeared in the AOS according to Lentulos own assessment: "Advice from practice: The probable mechanism of periapical infections ." (AOS No. 17 pp. 45–60).

In 1956 Lentulo ended his teaching activity at the age of 67, but continued to practice his dental work and published further articles in the AOS . When he was dependent on a wheelchair from 1969 onwards, the 80-year-old stopped working and retired to his property in Béthonvilliers .

In 1971 he was named Président d'honneur du 2 ème congrès des chirurgiens dentistes de France (Honorary President of the second congress of French dentists) and was awarded the silver Médaille de la Ville de Paris .

On January 27, 1981, Lentulo died at the age of 91 with his daughter in Gap. He was laid to rest in Béthonvilliers (about 150 km west of Paris 48 ° 13 ′ 19.1 ″  N , 0 ° 54 ′ 33.8 ″  E ).

Posthumous honors

On December 15, 1989 in Nice, in the St. Rochus Hospital in the center of dentistry that bears his name, a commemorative plaque was placed on the occasion of Lentulo's 100th birthday.
On February 6, 2003, the Senator and the Mayor of Nice, in the presence of the Prefect, Lentulos Family and Dental Associations, opened the Jardin Henri Lentulo (Henri Lentulo Park 43 ° 43 ′ 24.9 ″  N , 7 ° 17 ′ 5 ″  E ) inaugurated. The ceremony was performed by musicians from the Foreign Legion , who had come specially to honor one of their own.

Quotes

Henri Lentulo loved two sentences in particular:

  • "Return to the source and find your roof."
  • “If you're not a social anarchist at 20, then there's something wrong with your heart. If you're still 50, then something is wrong with your head. ” (Bernard Shaw)

Two statements by one of his students describe Henri Lentulo's personality very well:

  • “Henri Lentulo was above all a humanist - he was very sensitive to the social aspect of his invention: the root filler helped spread dentistry. He immediately understood its meaning, but always remained incredibly humble. "
  • "Deeply independent, gifted with a shining intelligence, a rare skill in operating, with remarkable experience and clinical understanding, that is how he became a master for all of us."
