Comparison of electrosurgery and formocresol as pulpotomy techniques in dog primary teeth.

The primary teeth of four dogs were treated using either a conventional formocresol or electrosurgical technique following pulpotomy. Pulps of the treated teeth were evaluated histologically for the presence of inflammation, fibrosis, necrosis, resorption, and reparative dentin formation. Results indicated that conventional formocresol pulpotomy technique is histopathologically superior to electrosurgery pulpotomy technique.

Management of trauma to primary and developing teeth.

Traumatic dental injuries to the young child can present both diagnostic and therapeutic challenges. Luxation injuries to the primary dentition are the most common injuries. Yet, they are the most controversial with regard to definitive treatment, prognosis, and sequelae. Damage to the developing teeth subsequent to primary tooth injury is often unavoidable and has permanent effects on the dentition. Diagnostic criteria, treatment options, and outcomes are presented in this article; however, treatment decisions are often based on patient behavior.

Prevalence location and patency of accessory canals in primary molars using dye penetration under vacuum suction technique--an in vitro study.

A study conducted on 120 primary molars (30 each of maxillary and mandibular 1st and 2nd molars) to find out the prevalence, location and patency of accessory canals and furcation formina using safranin red dye revealed the presence of accessory canals in 46 teeth (38.33 percent) with the major site being the furcation and furcation region.

Conservative multidisciplinary treatment approach in an unusual odontodysplasia.

An unusual case of odontodysplasia is presented, involving both primary and permanent dentition, with oligodontia of permanent teeth and hypoplasia, taurodontism and incomplete eruption of a first permanent molar. In order to improve the patient's appearance, occlusion and function, his intra- and inter-arch relationships were altered. To accomplish this, a multidisciplinary treatment approach was adopted, involving restorative and prosthetic treatments by a pediatric dentist, accompanied by periodontal surgery, endodontics and orthodontics.

Orthopantomography and the determination of majority age.

The problem of determining a subject's age to ascertain whether he can be criminally charged brings to prominence all the methods of investigation which can be used to define a person's biological age. The methodologies used to determine dental age still represent today the most sensitive means of arriving at this end. Researchers in Turin in 1980 elaborated an equational formula to determine a subject's presumable age by means of orthopantomography, basing the examination on the mineralization times of 4.5, 4.7, 4.8. After thorough checks carried out on sample groups of urban inhabitants, it was noted that the phases of mineralization of the 3rd molar can provide an answer to the judicial authorities' query as to whether the subject in question has come of age. The phase of mineralization of the 3rd molar is evaluated according to the table we have proposed during a previous conference and in another paper, which establishes 12 phases of mineralization. Focusing our attention on the final 12th phase, corresponding to the complete mineralization of the tooth roots, it was noted that this was present in 93 subjects, of whom 43 male and 50 female. A check of the personal data of these subjects revealed that for the male group age was between 6875 and 9396 days (between 18 years 10 months and 25 years 9 months), whereas for the female group age was between 6711 and 9275 days (between 18 years 4 months and 25 years 5 months). In other words, none of the subjects was found to be under 18 years of age.

Preventive goals in oral implantology.

Preventive dentistry is mainly concerned with caries and periodontal disease and little or no attention is paid to the prevention of alveolar bone loss. An overdenture contributes to the preservation of alveolar bone and offers a number of advantages in comparison to a conventional complete denture. After tooth extraction the atrophy of edentulous lower jaws can be prevented or delayed by using implants supporting an overdenture or a fixed mandibular prosthesis. Hydroxyapatite implants have been studied as submerged tooth root substitutes and have proven to be able to preserve the bulk of the alveolar ridge. A drawback of this submucosal implant is that the ridge maintenance depends solely on the physical presence of the hydroxyapatite implants. If implants support an overdenture or a fixed prosthesis they also play a role in maintaining the function of the bone in the different stages of reduction of the mandible. In this paper a classification for the different resorption stages of the mandible is presented and is used to determine the correct moment for preventive implantology. In addition the use of a lingualised occlusion is discussed as a contribution to the preventive goals in oral implantology.
