Literature reviews of oral lesions frequently lack an appropriate historical perspective, presuming that the mid- to late-twentieth century reports are the first valid reports available. The mid-nineteenth century dental journals, however, are replete with clinical, surgical, and microscopic descriptions of oral tumors and cysts. Most of these have never been referenced during the present century. The purpose of this article is to report the earliest dental journal references for a variety of odontogenic oral tumors and cysts. These references are derived from a canvas of all dental journals published from the first journal (American Journal of Dental Science) in 1839 to the appearance of Dental Cosmos and the organization of the American Dental Association in 1860.

Oral Pathology as a specialty of dentistry is traditionally presumed to have its origin in the 1930s and 1940s,[1] perhaps commencing with Bunting's Textbook of Oral Pathology,[2] Thoma's Oral Pathology,[3] or the first issues of the Archives of Clinical Oral Pathology,[4] and Oral Surgery, Oral Medicine, Oral Pathology.[5] The American Academy of Oral Pathology and the American Board of Oral Pathology were formed during this time period, preceded slightly by the first organizations devoted exclusively to Oral Pathology, the New York Institute of Clinical Oral Pathology and the American Dental Association's Registry of Dental and Oral Pathology.[6,7] An even earlier landmark was the 1915 comprehensive review by Bloodgood[8] of oral lesions, in the second volume of the Journal of the American Dental Association.

The first professorship of "Dental Pathology", however, originated much earlier, with the 1840 establishment of the Baltimore School of Dental Medicine.[9] The first text dedicated to Oral Pathology as we know it today was published shortly thereafter by Bond,[10] and, of course, Fouchard,[11], Jordain,[12] Hunter,[13] Bell[14] and others had reported even earlier on a variety of tooth anomalies.

In reality, it appears that the mid-nineteenth century was the time of the true birth of both Oral Pathology (Table 1). The age that saw an unprecedented, world-wide "mental stir" in consequence also saw the emergence of "modern" or organized dentistry.[30] This first "Golden Age" of dentistry, 1835-1860, began with dentistry "not a whit more respectable than the barber-surgeons of old times," and concluded with its establishment as an organized, science-based health profession with techniques and therapeutic successes not unlike those of the twentieth century.[30,31] The face of dentistry was absolutely changed to something unrecognizable from that which came before.[32]

A fascination for pathologic processes was an integral part of modern dentistry at its inception, as was a strong and apparently new belief that information should be openly and widely shared.[33] Approximately half of all scientific articles in the first volume of the earliest published dental journal were related to pathologic conditions of the mouth and jaws,[34] and the first truly comprehensive text for the dental profession in the United States, the 1829 classic by Bell,[14] dealt extensively with pathologic processes, including first reports of numerous oral diseases. Lester Cahn[1] believed that Sir Jonathan Hutchinson was the earliest Oral Pathologist, but the chairman of Baltimore's Department of Special Pathology, Thomas Bond, more correctly holds that distinction. Bond's insight was so remarkable that he was able to hypothesize etiologies and pathophysiologies which are still valid today. Leonard Koecker, an influential dental surgeon from London, was the first professional to actually be designated a Dental Pathologist in print.[20] He published an 1822 general text on dentistry, Principles of Dental Surgery, with observations said to be "based upon a correct knowledge of the laws of disease."[35]

Interest in pathology continued to grow as dentistry became a strong and independent health profession, and by 1860 many of today's well-established oral lesions had been reported in the various dental journals then publishing (Table 2). These accounts frequently anteceded the usually quoted "first reports" by several generations. Oral pyogenic granulomas, for example, were not well understood until Kerr's[36] 1951 analysis, yet Simon P. Hullihen, the "father of oral surgery", described one succinctly in an 22 year-old pregnant woman as early as 1844.[37] Hullihen documented a recurrence of his patient's gingival "aneurysm" with her second pregnancy. During the same year Westcott[38] described pregnancy gingivitis under the diagnosis of "uterine irritation"; Harris[15] had described it earlier as "hemorrhoidal discharge in dysmenorrhea."

Oral pathology papers frequently begin with historical reviews of the lesion or disease under discussion, usually mentioning the first cases identified. It seemed appropriate, therefore, to document the first actual dental journal reports of such entities. The attempt to do so is considerably facilitated by the fact that American dentistry, through its free exchange of innovative technology and scientific inquiry, its journals, national organizations, and its schools of dentistry, dominated the profession throughout the nineteenth century. Consequently, virtually all of the earliest journals were published in English and almost always in the United States (Table 2). While individuals from other countries published occasional textbooks of exceptional quality and insight, other countries lacked the cooperative spirit needed to assure a rapid expansion of professional knowledge. This first Golden Age of dentistry was a truly remarkable and uniquely American phenomenon, as declared in 1851: "dental surgery, as at present practiced, is almost an American creation, for although operations upon the teeth have been practiced since the days of the Pharaohs, and probably before, yet the rude and simple character of the early manipulations hardly give them a claim to be regarded among the effects of scientific art, and until comparatively lately, but very little improvement seems to have been made in this department of surgery."[39]

It is presumed that, because of this American dominance, references in early American dental journals are among the first reasonably accurate references to oral pathologic entities. It is hoped, however, that the present paper will stimulate additional investigation into early references of such lesions, especially in textbooks, which were much less widely circulated than journals and are much more difficult to obtain today.

A listing of nineteenth century dental journals [40] was supplemented by a four-year systematic perusal of journals in the libraries of West Virginia University, the University of Minnesota, the Mayo Clinic, and the National Library of Medicine. Table 2 lists all dental journals published, in any language, between 1839 and 1860. Almost all English-language articles published in all volumes of each journal in Table 2 were reviewed for references to oral pathologic entities. While most diagnoses were obvious, even though the lexicon was different from that in use today, educated guesses were occasionally made for several lesions since some early investigators neglected to provide detailed histologic descriptions. All lesions reported from 1839-1860 were recorded, whether first reports or not, and additional references are available upon request.

Odontogenic Neoplasms

The first dental journal reports of oral pathologic entities dealt with odontogenic anomalies (Figure 1). Dentists were beginning to share clinical information on a wide scale and the odd case noted in clinical practice was specifically sought by editors. One of the most well-accepted anomalies was then called "exostosis," an enlargement at the apex of the root or "bone" of an extracted "fang".[41] Such lesions were thought to be a major cause of tooth-ache pain and inflammation of the "dental nerve" (pulp), a natural assumption considering that they were only found upon extraction of painful, cariously destroyed teeth.[21,42-44] By 1851, Vandenburgh [45] hypothesized that pulpal inflammation caused this lesion and it was, therefore, not a true exostosis.

Harris[15] and Lee[46] believed that multiple cases in one individual were the result of "constitutional causes" rather than inflammation. Today we refer to this as hypercementosis and know it to represent excessive cementoblastic activity secondary to hypereruption of a tooth. We still accept one "constitutional" cause, Paget's disease of bone, for multiple hypercementoses.[47]

A few exostoses were much too large to conform to a hypercementosis diagnosis and were obviously benign cementoblastomas. Several were reported to have completely obliterated the ipsilateral maxillary sinus.[48,49] The very first dental journal reference to an odontogenic neoplasm was a 7 cm. cementoblastoma of a maxillary molar, reported in the inaugural volume of the American Journal of Dental Science (AJDS), the official publication of the first national dental association and the only dental journal accepted by the early American Medical Association as a legitimate medical journal.[50,51] This same entity became the first odontogenic lesion reported with microscopic confirmation (Figure 2), almost a century before Norberg[53] published the paper most usually quoted as the first report of this lesion.

Table 3 provides first reports of other odontogenic neoplasms. The first journal report of a complex odontoma was in a 25 year old female and was most unusual in that it erupted with the underlying tooth.[42] Without such eruption, of course, this lesion would not have been noted in a age without radiographs. The complex odontoma with the most definitive microscopic confirmation, however, was not reported until Forget's[49] superb paper translated in the first volume of Dental Cosmos (Figure 3). The first unequivocal cases of compound odontoma, one with at least 25 distinct teeth and another with a gross specimen drawing confirming the diagnosis, were reported in 1854 and 1858, respectively.[61,63] While these are the first journal reports of odontomas, it was probably Pierre Fouchard[11] who provided the first accurate description of these lesions. Oudet[64], in 1809, suggested that they were of dental origin, but the term "odontome" was not applied until 1868.[65] They were undoubtedly the oldest recorded odontogenic neoplasms, having been reported in a 500,000 year old fossilized horse.[66]

An earlier journal report of an intraosseous neoplasm might possibly have dealt with a complex odontoma, discovered only because of its large size.[59] But the surgical description is more appropriate to a central ossifying/cementifying fibroma. The first unequivocal case of the latter entity was one of considerable size, contained numerous microscopic foci of dark globular cementum, and was not published until 1865 (Figure 4).[67]

The odontogenic (nonossifying) fibroma is an entity which, until recently, was frequently confused with simple fibrous hyperplasia of the parafollicular connective tissues,[68] but Adams[60] reported a "circumscribed fibrous tumor" around the crown of an impacted mandibular molar which seems large enough to justify it as the first report of a true odontogenic fibroma. Also, Furgusson[62] reported a similar case which was gelatinous rather than fibrous, hence was likely an odontogenic myxoma.

Other odontogenic neoplasms were difficult or impossible to identify without detailed microscopic description. It is probable that none were actually reported, or were reported with so little descriptive detail as to defy proper diagnosis. Thoma[3] listed only four types of odontogenic neoplasms as late as 1947. Ameloblastomas, which had been reported in Europe by 1827 and inspired hundreds of publications after the first Golden Age,[68-70] were not reported between 1839 and 1860. Wedl[71] provided the first histopathologic description in 1853, indicating that this "cystosarcoma or cystosarcoma adenoides" possibly originated from a tooth bud or dental lamina. The first histologic drawing of an ameloblastoma was not published until 1871 and, ironically, depicted one of the most recently delineated types, the unicystic ameloblastoma.[72] In fact, the early study of this entity was considerably hampered by the apparent inability of investigators to separate odontogenic cysts from odontogenic tumors,[70] even though Neumann[73] seems to have made that distinction in 1867 when he described the first ameloblastoma arising in a dentigerous cyst.

Although not true odontogenic neoplasms, ovarian teratomas or dermoid cysts were well known to frequently contain teeth, almost always within bony "sockets."[74] In his article, Cone also referred to the fact that Brodie had already reported a case of "a jaw with full grown teeth" by 1848.

Odontogenic Cysts

Cysts of the jaws were noted only when they produced cortical expansion or some other visible alteration of surface tissues. The single exception was also the first cyst reported in a dental journal: the periapical cyst (Table 3). These cysts were referred to simply as "sacs" and were a routine experience for busy dental surgeons extracting and examining carious teeth. By the 1830s dentists were almost as familiar with periapical pathoses as we are today, although many believed that the periapical lesion produced tooth death, rather than vice versa.[17] Noncystic periapical lesions were described as inflammations, granulations,, abscesses, and suppurations, and it was well known that facial or alveolar fistulae could result from them (Figure 5).

Dentigerous cysts were described as early as 1778 in France,[67] but were not well delineated until 1842, and were not illustrated in a journal until 1859 (Figure 6).[49,55] These cases were reported approximately a century after Scultet[75] first described jawbone cysts as "liquid tumors." The concept of a benign, epithelial-lined cystic space with internal pressures capable of producing bony expansion was formed during those early years.[75]

Several cystic lesions were aggressive enough to be classified today as odontogenic keratocysts or unicystic ameloblastomas. The first large cyst was Dornbluth's[57] 1844 description of a multilocular dentigerous cyst or "encysted tumor" which had entirely filled the antrum and distorted the orbital floor. This case has all the earmarks of an odontogenic keratocyst, but a microscopic description is lacking. The aggressive nature of such lesions is emphasized by contemporary diagnoses used, such as "cystic sarcoma" and "cystic carcinoma".[72] It is probable that the multilocular cyst found by Salama and Hilmy[76] in the mandibular ramus of a 2,800 B.C. Egyptian mummy was a keratocyst. It was not associated with an impacted tooth and had greatly expanded the overlying cortices, causing pathologic fracture. This skull also contained a dentigerous cyst around the crown of an impacted maxillary cuspid (Gorlin's syndrome, perhaps?).

The eruption cyst help special significance for early dental surgeons.[59] The anatomy of the trigeminal nerve had recently been described by the Englishman Charles Bell[77] and a direct connection between teeth and the brain was proven for the first time -- a connection first proposed by Aetius soon after Galen's treatise on teeth.[78] Since many children suffered from viral or other encephalitis and meningitis attacks at a period of life similar to the eruption of teeth, it was assumed that tooth eruption, and particularly its "severe" forms (with eruption cysts), was the cause of "brain fever".[79] The universal acceptance of this concept is perhaps best illustrated in Charles Dicken's[80] Bleak House, wherein a sickly child is assumed to be dying from "a difficult teething". The logical treatment for convulsions and stuporous fevers became, quite naturally, the surgical incision of gingival tissues overlying eruption cysts and erupting teeth. This treatment appeared to be successful, of course, because brain fevers typically lasted 7-14 days, presuming death did not intervene. Such treatment came to be known as "scarification" and was used also on Epstein's pearls or gingival cysts of newborns.[56]

It is hoped that the present paper will prove to be a stimulant to more extensive and more in-depth historical reviews of oral pathologic lesions. At the very least it offers early references which can be used in introductions to clinicopathologic investigations, references heretofore difficult to identify because they were in print several decades before Index Medicus began publication.[121] As a further aid, a databank of lesion-specific references has been created for the years 1839-1860. This material is available upon request and will be extended into later years as time permits. Additional references from outside the dental journals of the first Golden Age are welcome and will be incorporated into the databank upon receipt.

Legends for Figures (Figures are not yet placed on this page)

Figure 1: Case of dilaceration, shown from three angles is the first picture of an oral anomaly reported in a dental journal.[61] Such cases were thought to result from the fusion of the remnants of fractured roots, as with bone healing, and were initially called "osseous union."

Figure 2: Gross appearance of a benign cementoblastoma of a maxillary bicuspid.[52] The "considerable incrustation of hypertrophied tooth-bone" was destroying the normal tooth.

Figure 3: Gross and microscopic appearance of a complex odontoma in situ in the mandible.[49] Dentinal tubules, as depicted here, were a recently discovered phenomenon.

Figure 4: Gross specimen of central cementifying fibroma in a periapical location but not attached to the tooth. Microscopic drawings depict globular dark calcified structures, presumably cementum, in a dense fibrous stroma.[67]

Figure 5: A multitude of periapical pathoses, including fistula formation, was depicted in this 1840 composite drawing.[17] Note the external caries of the teeth, exemplifying the new acceptance of an external etiology for tooth decay.

Figure 6: Dentigerous cyst in situ in the posterior mandible.[49] The distinction between cysts and neoplasms, especially malignant neoplasms, was unclear, hence hemimandibulectomy was the treatment of choice for large "cystic carcinomas".
