Versatility of an 810 NM Diode Laser in Pediatric Dentistry
Purpose: During the last few years, the use of laser techniques has dominated the
dentistry world as an alternative to different traditional methods or in combination with
these. Diode laser is the most frequently used in dentistry due to its reliability, versatility
and convenience, together with its handiness and simple setting-up. The aim of this paper
is to review the use of diode laser (810 nm) in pediatric dentistry.
Methods: We illustrate, according to the recent literature review, the clinical
approach in deciduous teeth endodontics (like pulpotomy and root canal therapy) and in
soft tissues surgery with description of techniques used in labial and lingual fraenectomy,
operculectomy for tooth retention and hypertrophic lesions removal.
Results: 810 nm diode laser has been used in all these different therapies at 0,8 to 3
W power either in continuous or pulsed mode. Diode laser has one of the most versatile
ranges of wavelengths available due to the number of different therapies that can be
performed in several tissues
Riga-Fede Disease and Neonatal Teeth
AIM: The aim of this study is to present a case of Riga-Fede disease (RFD). RFD is a benign and uncommon mucosal disorder, characterized by an ulceration of the tongue, often caused by repetitive traumatic injuries due to backward and forward movements of the tongue over the mandibular anterior incisors. RFD is most commonly associated with the eruption of primary lower incisor in older infants or natal-neonatal teeth in newborns.
METHODS:
A 2-month-old female infant was referred to our Paediatric Dentistry Unit for ulceration (13 mm diameter) on the ventral surface of the tongue and neonatal teeth. The extraction of neonatal teeth was selected as treatment of choice, over more conservative treatments, for the rapid resolution of the lesion and for the limited risk of inadequate nutrients intake. The extracted teeth underwent a macroscopic/microscopic examination. The complete healing of the lesion took 4 weeks; subsequently, the infant, revised at the 1-year follow-up visit.
CONCLUSION: Early detection of RFD is recommended because such lesions properly may induce deformity or mutilation of tongue, dehydration, inadequate nutrients intake by the infant and growth retardatio
Black Stain: studio clinico e microbiologico
Aim of the work. Objectives of the study are the following: quantify and identify microorganisms in the dental plaque
of patients with black stain; test in vivo and in vitro efficacy of two mouthwashes; identify a protocol.
Materials and methods. The research protocol included a clinical and a microbiological stage. 63 patients between 2
and 15 years with black stain were selected, then divided into three groups. In Group 1 (19 patients) no mouthwash was
prescribed. In Group 2 (21 patients) was prescribed a fluoride mouthwash (Sodium Fluoride 0,05%). In Group 3 (23
patients) a chlorhexidine 0,12% mouthwash was prescribed. The microbiological stage provided analysis of pigmented
plaque through bacterial count and identification tests and aura of inhibition on agar plate to evaluate the inhibitory
power of the mouthwashes examined.
Results. It was highlighted a strong decrease in index of pigmented plaque in Group 3 than Groups 1 and 2. The
microbiological analysis revealed a decrease in bacterial count higher in Group 3 than Groups 1 and 2. The bacteria
identified the most were Clostridia. The chlorhexidine mouthwash was more effective than fluorine mouthwash on
bacterial growth.
Conclusions. The use of mouthwash in conjunction with periodic specialist visits is essential to assist oral hygiene at
home. It is assumed that the mouthwash with chlorhexidine 0,12% is the most effective in reducing black stain in vivo and
in vitro
Childhood obesity and skeletal-dental maturity
The aim of this cross-sectional study was to evaluate the skeletal maturation assessed through cervical vertebral maturation (CVM) and dental age, in normal weight, pre-obese and obese patients, using the Body Mass Index (BMI) and the Dual energy X-ray Absorptiometry (DXA)
Research of non-specific hyperreactivity of upper airways in subjects with gastro-esophageal reflux (G.E.R.): Preliminary reports
An association between asthma and gastro-esophageal reflux (GER) is well recognized but the underlying mechanism is still unclear. The authors suggest that could exist an association between GER and upper airways hyperreactivity and this association could represents the mechanism underlying the lower esophageal sphincter releasing, that determine the reflux. In fact they suppose that, the noxious injury of acid reflux follows a course that could be: pharynx → larynx → bronchi → 1/3 inferior of the esophagus → reflux. From these presuppositions the authors carried out a study on the possible relationship between GER and non-specific hyperreactivity of upper airways on 14 subjects, divided in 2 groups: 10 subjects with functional GER, 4 subjects suffering from GER caused by hiatus hernia as control group. All patients had a thorough medical history, ENT examination with rigid and flexible endoscope, anterior Rhinomanometry (RRM), skin-test for inhalant and alimentary allergens, RAST, audiometric exam, non-specific nasal provocation test (NSNPT) with histamine, using as control the number of sneezes. From a through analysis of objective examination and from the results of the NSNPT with histamine resulted that all subjects with functional GER were rhinopathics. In all tests both in vivo (Skin-test) and in vitro (RAST) for the most common allergens (pollens-inhalant-mycophites-alimentary) the results were negative. The authors also found an involvement of paranasal sinuses that raised: 91% in the patients with recurrents phlogosis due to non specific nasal hyperreactivity; 40.9% in the allergic subjects (20% in the Graminacee +; 32% in the Parietaria O. +; 76% in the Dermatophagoides Pt. +; others 4%); 100% in the ASA-intollerance subjects. The NSNSPT with histamine showed in the group with functional GER a hyperreactivity with sneezes in 6/10 subjects, and 1/4 subjects of the group with GER with hiatus hernia. The RRM variations showed an unilateral nasal hyperreactivity in 6/10, bilateral in 3/10 subjects of the group with functional GER. In the group with GER with hiatus hernia only 1/4 subject showed reliable unilateral RRM variation. From the analysis of data resulted that subjects with functional GER showed a completely involvement of the upper airways and not only of the pharynx and larynx, caused by non specific hyperreactivity at the NSNPT with histamine, associated with a chronic pathology
Thyroid surgery in geriatric patients: a literature review.
BACKGROUND: Thyroid disease is common in the elderly population. The incidence of hypothyroidism and multinodular goitre gradually increases with age. In view of a growth of aging population, we performed a literature review about the feasibility of thyroid surgery in the elderly. METHODS: We conducted a literature search in the PubMed database in September 2012 and all English-language publications on thyroidectomy in geriatric patients since 2002 were retrieved. The potential original articles mainly focusing on thyroidectomy in elderly patients were all identified and full texts were obtained and reviewed for further hand data retrieving. RESULTS: We retrieved five papers based on different primary end-point. Four were retrospective non randomized studies and one was prospective non randomized study. At last 65, 70, 75 and 80 years were used as an age cut-off. All studies evaluate the indications of thyroidectomy in geriatric patients, postoperative morbility and mortality. Only one study specifically assesses the rate of the rehospitalization after thyroidectomy among the elderly. CONCLUSIONS: Thyroid nodules are particularly important in elderly patients, as the incidence of malignancy increases and they are usually more aggressive tumors. An age of at least 70 years is an independent risk factor for complications after general surgery procedures. Thyroid surgery in patients aged 70 years or older is safe and the relatively high rate of thyroid carcinoma and toxic goiter may justify an aggressive approach. A programmed operation with a careful pre-operative evaluation and a risk stratification should make the surgical procedures less hazardous, specially in 80 years old patients with an high ASA score
