Endodontic Treatment of Primary Molars with Antibiotic Paste: A Report of 38 Cases.

OBJECTIVE: This study presents 38 cases of primary molars with necrotic pulps treated with antibiotics-based paste. CASE REPORT: The technique consisted of necrotic tissue removal of the pulp chamber, using spoons excavators and low speed drills. Pulp cavity was washed with saline solution and dried with sterile cotton balls. Then an antibiotic paste composed of chloramphenicol, tetracycline, zinc oxide and eugenol - CTZ paste - was inserted at the entrance of root canals. Patients were evaluated clinically and radiographically at different times. The criteria that defined clinical success were the lack of periapical abscess and mobility compatible with chronological age. Radiographic assessments consisted in absence of radiolucency in the region of root bifurcation and pathological bone resorption. CONCLUSION: There were 100% and 93% of clinical and radiographic success, respectively. The results suggest that the CTZ paste is an optional therapy for pulp of primary molars.

[Spontaneous dental abscesses in familial hypophosphatemic rickets]. / Multipele spontane odontogene abcessen bij familiaire hypofosfatemische rachitis.

Symptoms of familial hypophosphatemic rickets are growth retardation, the formation of O- or X-legs, pain of the joints, spontaneous dental abscesses, and delayed tooth eruption. The dental symptoms are predominantly attributable to the demineralization of dentin. In absence of adequate preventive measurements,familial hypophosphatemic rickets may lead to spontaneous pulpal necrosis. The prophylactic application of occlusal sealants might be effective in preventing abscess formation.

In vivo evaluation of lesion sterilization and tissue repair in primary teeth pulp therapy using two antibiotic drug combinations.

AIM: The purpose of this study is to evaluate and compare the clinical and radiographic effectiveness of Ciprofloxacin, Minocycline, Metronidazole combination with Ciprofloxacin, Minocycline and Tinidazole combination when used for Lesion Sterilization and Tissue Repair in primary teeth. METHOD: 25 healthy children, visiting Dept. of Pediatric & Preventive Dentistry, D.A.P.M.R.V. Dental College, Bangalore, India, aged between 6-9 years who were having 30 infected primary teeth are selected and divided into 2 groups. In Group A, a mixture of 3mix-MP Ciprofloxacin, Metronidazole and Minocycline was placed on the floor of the pulp chamber covering the root canal orifices. In Group B a mixture of Ciprofloxacin, Tinidazole and Minocycline was placed as a layer on the floor of the pulp chamber. The procedure was completed in a single visit. Post operative clinical evaluation was done after 1,6,12 and 24 months. Postoperative radiographic evaluation was done at 6, 12 and 24 months. RESULTS: No statistically significant difference is observed between both the groups and a combination of Ciprofloxacin, Minocycline and Tinidazole antibacterial drugs can be used on teeth pulpally involved with physiologic root resorption. CONCLUSION: After a 24 Month follow up, we can conclude that primary teeth with the periradicular lesions, can be conserved by using combination of Ciprofloxacin, Minocycline and Tinidazole antibacterial drugs.

Familial hypophosphatemic vitamin D-resistant rickets--prevention of spontaneous dental abscesses on primary teeth: a case report.

Familial hypophosphatemic vitamin D-resistant rickets is a hereditary disease generally transmitted as an X-linked dominant trait and characterized by distinctive general clinical signs. Dental features include spontaneous dental abscesses that occur in the absence of a history of trauma or dental decay. The challenge for the dentist is to prevent and treat these lesions. This report describes the case of a young hypophosphatemic boy with abscesses. In this case, the application of fluid resin composites with a self-etching primer bonding system to all primary teeth prevented abscess formation for more than 1 year and thus avoided endodontic treatment or extraction. This constitutes a new approach to the prevention of spontaneous abscesses on primary teeth in children with familial hypophosphatemic rickets.

Effect of orifice plugs on periapical inflammation in dogs.

Gutta-percha (G) and sealer do not resist coronal leakage. In this study, the effect of orifice plugs using dentin-bonding/composite resin(C) or IRM on coronal leakage was evaluated in vivo. Sixty-one premolar roots in three beagle dogs were instrumented and filled with G and AH 26(S), or G alone. The coronal 2 mm was replaced with C or IRM, or left untreated. The access cavities were kept open for 8 months, the dogs were killed and the periapical regions of the roots were histologically examined. Periapical inflammation was observed in 89% of the group without plugs, but in those with plugs, the occurrence was decreased to 39% (C + G + S), 38% (IRM + G + S) and 58% (C + G), respectively. Furthermore, severe inflammation was observed in 50% of the former group but only 0 to 17% of the latter. The substantial reduction in apical periodontitis by the use of coronal plug underscores the clinical importance of providing an additional barrier to coronal leakage in comparison to that provided by gutta-percha and sealer alone.

Infected total knee replacement following a dental procedure in a severe haemophiliac.

This article documents the late infection of a total knee replacement in a haemophiliac following a dental procedure. It underlines the need for reconsideration of the current British guidelines regarding antibiotic prophylaxis for dental procedures in patients with total joint replacement.

[Rational use of antibiotics by the dentist can prevent microbial resistance]. / Rationeel antibioticagebruik door tandarts kan resistentie voorkomen.

Worldwide resistance of microorganisms to antibiotics is becoming a problem of major concern. An antibiotic policy which tries to control the development of resistance by rational use is needed in all fields where antibiotics are prescribed. In dental practice, apart from endocarditisprophylaxis, prophylaxis is leukopenic patients and prophylaxis after dental implants, antibiotics can be used to support local therapy of an dentoalveolar abscess or refractory periodontitis. In the majority of these cases, a small spectrum penicillin is therapy of choice.

Effect of methotrexate-induced neutropenia on rat periapical lesion.

We investigated the effect of methotrexate-induced neutropenia on periapical lesions in rats. Periapical lesions were prepared in all animals by pulpal exposure. The animals were injected with methotrexate three times a week 4 weeks before or after the pulpal exposure. The periapical lesion of each animal was examined histologically, histometrically, and immunohistochemically. The total leukocyte count and neutrophil count in the peripheral blood decreased after the injection. The methotrexate-induced neutropenia elicited after pulpal exposure did not change the status of the periapical lesion, whereas the neutropenia before the exposure inhibited the development of the lesion. Moreover, the neutropenia before pulpal exposure resulted in an inhibition of infiltration of neutrophils into the lesion.

Extension of dental abscess to the orbit.

A week after dental treatment, a dentoalveolar abscess developed in a 14-year-old boy. Surgical intervention was needed to evacuate pus and remove the cause of infection. It is suggested that initially establishing drainage after dental treatment would have prevented the sequela that ensued.

[Preventive removal of displaced teeth]. / Müssen verlagerte Zähne prophylaktisch entfernt werden, ja oder nein?

Using the data acquired from our catamnestic survey, we were able to establish a broad catalogue of complications involved with impacted and displaced teeth. Given these complications, it is not medically responsible to leave impacted and displaced teeth in the jaw, even if they are asymptomatic. The risks increase considerably with age. Late operative removal of such teeth can be a dangerous intervention due to local complications such as abscesses, cysts, osteomyelitis, tumors, systemic diseases, and age-related changes in the cardiovascular system.
