Dental health behavior of children with BBTD treated using general anesthesia or sedation, and of their parents in a recall examination.

The aim of the study was to assess the dental status and dental health behavior of children with Baby Bottle tooth Decay treated using general anesthesia or sedation, and the dental health behavior of their parents in a recall examination. The study population consisted of sixty-five children, among whom thirty-four were treated using general anesthesia and thirty-one using sedation. The recall examination included a full dental examination from which the children's dif index could be drawn. Loe's plaque index was used to assess the amount of plaque on the teeth. Sociodemographic information and the dental health behavior of the parents and children were obtained. Plaque index was similar in the general anesthesia and sedation groups. The parents of the general anesthesia group were younger than the parents of the sedation group (35.0 +/- 6.7 and 38.8 +/- 6.2 for the fathers, and 32.4 +/- 5.9 and 34.9 +/- 5.3 for the mother, respectively). More firstborn children were treated using general anesthesia than using sedation. Significantly more siblings were treated in the sedation group. Children treated using sedation had significantly more siblings treated in the same mode. Parents of the children in the general anesthesia group were significantly more involved in brushing their children's teeth than the other group. In the sedation group, more children brush their teeth without parental help. Significantly more children in the general anesthesia group reduced their sweet consumption than in the sedation group. We conclude that preventive behaviors were more frequently adopted among the families of children treated using general anesthesia.

Management of the crying child during dental treatment.

The purposes of this study were: (1) To present parents' attitudes toward their child's crying in the dental environment. (2) To suggest a classification of crying children, and discuss its management implications. One hundred and four parents accompanying their children to dental treatment completed a questionnaire assessing the following: the tendency of the child to cry, the preferred approach of the operator to the crying child, and how the parents perceive their own role in such a case. Also the operator's assessment of the child's cooperation and of the child's tendency to cry were recorded. The sociodemographic variables of the parent were recorded, but no association was found with the dependent variables. Fifty-three percent of the parents assessed their children as having a tendency to cry, while only 25 percent children were assessed as such by the operators. Seventy-three percent of the parents preferred that the operator cease the treatment and calm the crying child before resuming. Sixty-nine percent of the parents stated that they should always help to manage the child, when crying takes place. Eleven children who were assessed by the operators as having a tendency to cry cooperated well during the treatment. The successful completion of dental treatment of a crying child is viewed as a partnership of the dentist and the parent. It is important that the dentist informs the parent about the method to be used, and have their consent. A new classification of the crying child is suggested.

The use of imagery suggestions during administration of local anesthetic in pediatric dental patients.

The aim of this study was to evaluate the effects of suggestion before and during the administration of local anesthesia to children. These effects were then observed and correlated with social, behavioral and dentally related variables. Eighty children between the ages of three and sixteen years and who required at least one injection of local anesthesia were monitored. Retrospective examinations of their dental records provided the information regarding the behavior and dental treatment histories of the patients. All other data were provided through observation during the dental treatment phase. During the first treatment session, before the injection, each child was asked to select a favorite, pleasant memory or image. Where children had difficulty in identifying an image, one was proposed by the dentist. After an image had been chosen, the patients were asked to concentrate on the image and to visualize it during the procedure. The majority of children had chosen their own images, and significantly visualized the same images throughout the injection procedures. Image selection and visualization had no association with gender, age, the parent's assessment of the child's behavior, previous dental experience, behavior (both past and present) or, management techniques (both past and present). We conclude that imaging techniques may be successfully utilized in the administration of local anesthesia to young children (from three years of age) in an effort to mitigate untoward, pain-related stress.

Tongue piercing and insertion of metal studs: three cases of dental and oral consequences.

"Body art" is a fashion that appears to be gaining popularity worldwide. There are many risks and potentially adverse results associated with tongue piercing. Pain (the procedure is performed without anesthetics), post-placement edema and the risk of prolonged bleeding, if the blood vessels are punctured during the piercing, and fracture of tooth structures, are but a few of the risks. The purpose of the present article is to describe the consequences of three cases of tongue piercing in which metallic barbell-shaped studs were inserted: the consequences include the fracture of tooth structure, caused by the device knocking against the teeth; and inflammation and edema occurred as a result of the piercing of the tongue.

Reactions of children to maxillary infiltration and mandibular block injections.

PURPOSE: The purpose of this study was to assess children's reactions to the administration of local anesthetic injection in the mandible and in the maxilla, and to study their sensation of pain after each type of injection. METHODS: Twenty-six children between the ages of 4 to 6 (mean age 5.3+/-0.7 years), and 34 children aged between 7 to 10 (mean age 8.1+/-1.1 years,) who were undergoing dental treatment in a pediatric dental clinic, were selected for this study. A random crossover design was used. Each patient was randomly assigned to receive either maxillary infiltration or mandibular block on the first visit, and the remaining local anesthesia on the second visit. During the injection, the modified Behavioral Pain Scale, was used. It comprised the following parameters: a) facial display, b) arm/leg movements, c) torso movements, and d) crying. Immediately after administering the local anesthesia, children were asked to rate their feeling according to the Facial Affective Scale. RESULTS: The children in each group responded positively to both techniques revealing that there was no difference in either one. Subjective and objective evaluation disclosed no difference when mandibular block was administered during the first or second visit. Regarding the objective evaluation, in all parameters, more children reacted positively during administration of mandibular block than during maxillary infiltration. CONCLUSION: a) mandibular block and maxillary infiltration are similarly accepted by children when first administered, and b) children may feel inconvenience or pain and react by crying, yet may report a positive feeling in general.

Long-term change of viability of neuron functioning and its possible behavioral consequences in the adult Aplysia.

1. In Aplysia of different ages, three well defined behavioral responses and their substrates were examined. 2. Two of the behaviors and their substrates are age-sensitive, the gill withdrawal reflex, and osmoregulation. They are sensory-dependent for their activation. The third, the gill respiratory pumping movements, GPM, and its substrates is age-invariant. It is initiated by a network in the CNS, and modulated by sensory input. 3. Age-sensitivity of a neuron appears dependent on its pathway: the pathways mediating sensory-initiated behavior are more vulnerable to aging than the pathway mediating CNS-initiated behavior. 4. a) The age-sensitive, GWR, gill withdrawal reflex, in unrestrained animals and in reduced preparations conforms to the age-dependent reduced functioning of L7, the major mediator of the reflex. b) Whereas, the age-invariant GPM conforms to the age-independent functioning of LDG1, a major contributor to GPMs. c) The age-related slowing of osmoregulation is consistent with the lack of response in the putative water balance neuron, R15, to stimulation of osmoreceptors by dilute seawater. 5. Age-sensitivity of L7 is defined by its reduced function, decreased facilitation at its terminals, reduced input resistance, and remodeling of junctions in the muscles it innervates. This is in contrast to the age-invariance of these properties in LDG1 and of the junctions in muscles it innervates. Thus far, the age-sensitivity of R15 is revealed by its reduced responsiveness to synaptic input, reduced input resistance, and little response to osphradial stimulation. 6. Age-sensitivity of the GWR, osmoregulation and of their substrates is not necessarily maladaptive.(ABSTRACT TRUNCATED AT 250 WORDS)

Baby bottle tooth decay and complications during pregnancy and delivery.

The purpose of the study was to investigate an association between maternal and/or fetal complications during pregnancy and/or delivery and the occurrence of baby bottle tooth decay (BBTD) in the infant. The study population comprised 50 mothers of infants with BBTD (BBTD+ mothers): 50 mothers of aged-matched children with similar eating and bottle-use habits but without BBTD (BBTD-) served as comparisons. Interviews with the mothers focused on pregnancy complications (vaginal bleeding, premature uterine contractions, viral or bacterial infections, hospitalization, diabetes, or other causes of high-risk pregnancy), mode of delivery (normal or instrumental), fetal distress, gestational age, birth weight, and mother's age at delivery. Chi-square analysis and the Student's t-test were used to analyze the data. Pregnancy complications and instrument delivery/cesarean section were significantly higher in the BBTD+ group than in the controls (P = 0.0001 and P = 0.0004, respectively). In the BBTD+ group, vaginal bleeding/premature uterine contractions were most frequent (50%), while in the BBTD- group high-risk pregnancy dominated (20%). Normal deliveries were more frequent in the BBTD+ mothers (68%) than in the comparisons (40%). Gestational age and baby's birth weight did not differ between the two groups. The mean age of the BBTD+ mothers was significantly lower than that of the controls (P = 0.013). The results suggest that babies born after maternal complications during pregnancy or babies who experience a traumatic birth must be considered to be at risk of developing BBTD when exposed to excessive bottle nursing.
